y = 5x + 4 is the equation of the line whose slope is 5 and y intercept is (0,4)
Solution:
Given that we have to write the equation of the line whose slope is 5 and y intercept is (0,4)
The equation of line in slope intercept form is given as:
y = mx + c -------- eqn 1
Where, "m" is the slope of line and "c" is the y - intercept
Given that,
Slope = m = 5
Also, y intercept is (0,4)
Therefore, c = 4
Substitute c = 4 and m = 5 in eqn 1 to get equation of line
y = 5x + 4
Thus the equation of line is found

please help What is the domain of the following function?
Answer:
Let's use these two sets given to explain what is the domain.
Each value from the left set is x, and from the right is f(x).
If we plug any x from the left set in the function, we'll get f(x) that corresponds to it and that's exactly what the arrows are showing.
Domain of the function is, basically, a set of all values x can have.
In this case, it's easy to see, those are all members of the left set (-6, 1, 5, 8), but sometimes this set can have lots and lots of members, even infinity.
Are the ratios 3:7 and 1:2 equivalent
Answer:
Step-by-step explanation:
no they are not equivalent
Answer:
No
Step-by-step explanation:
3 divided by 3 gives you 1, whatever you do on top you have to do in the bottom .
7 divided by 3 does not give you 2. Since you cant apply the same rule of divided by 3 and getting a whole number. They are not the same.
Two expressions are below.
M = 4(2x + 6)
N = 8x + 10
Part A:
Apply the distributive property to write an expression that is equivalent to expression M.
Part B:
Explain whether or not expressions M and N are equivalent for any value of x.
Label your answers to both parts of the problem in the response box.
Answer:
part A:
M = 4(2x + 6)
= 8x + 24
part B:
option 1) i think the x value is equal for both M and N since they have the value 8.
option 2) If you meant to solve M and N with an EQUATION then here's your answer:
8x+24 = 8x+10
24≠10 (you subtract 8x when taken to the other side)
So, the answer would be NO SOLUTION
Final answer:
To apply the distributive property to expression M, multiply each term inside the parentheses by 4, resulting in M = 8x + 24. Comparing this to expression N, which is N = 8x + 10, one can see that M and N are not equivalent because their constant terms differ.
Explanation:
Part A: Equivalent Expression for M
To find an equivalent expression for M, we use the distributive property which states that multiplying a sum by a number is the same as multiplying each addend by the number and then adding the products. Therefore:
M = 4(2x + 6)
Apply the distributive property to get:
M = (4 × 2x) + (4 × 6)
M = 8x + 24
Part B: Are M and N Equivalent?
To determine if M and N are equivalent expressions, we must compare the expressions that we have for M and N:
M = 8x + 24
N = 8x + 10
Since the coefficients of x are the same but the constant terms are different, the two expressions are not equivalent for any value of x.

Step-by-step explanation:
A square and a circle are used as sample designs for a tiling project. The length of an edge of a square is two times the length of the radius of a circle.
Find the ratio of the area of the circle to the area of square using the given radii.
Select either Choice 'A' or Choice 'B'
For radius x, Choice 'A' π/4 is the correct answer.
For radius 10x, Choice 'B' π/4 is the correct answer.
For radius 100x, Choice 'B' π/4 is the correct answer.
Step-by-step explanation:
The Area of the circle = πr^2, where "r" is the length of the radius.
The Area of square = a^2, where "a" is the length of an edge of a square.
CASE 1 :
Substitute radius r = x and edge length a = 2x,
Area of circle = π*x*x = πx^2
Area of square = 2x*2x = 4x^2
The ratio of the area of the circle to the area of square = πx^2 / 4x^2 = π/4
Choice 'A' π/4 is the correct answer.
CASE 2 :
Substitute radius r = 10x and edge length a = 20x,
Area of circle = π*10x*10x = 100πx^2
Area of square = 20x*20x = 400x^2
Ratio of the area of the circle to the area of square = 100πx^2 / 400x^2
= π/4
Choice 'B' π/4 is the correct answer.
CASE 3 :
Substitute radius r = 100x and edge length a = 200x,
Area of circle = π*100x*100x = 10000πx^2
Area of square = 200x*200x = 40000x^2
Ratio of area of the circle to the area of square = 10000πx^2 / 40000x^2
= π/4
Choice 'B' π/4 is the correct answer.
Find the indicated side of the triangle !!!
Answer:
The correct answer is b = 6 √3 units
Step-by-step explanation:
Let's recall that we can use the following ratio for the sides of a 90 - 60 - 30 triangle:
1 : √3 : 2, where 2 is the hypotenuse.
Upon saying that, we have that in our triangle:
Hypotenuse = 12 units
a = 6 units
b = 6 √3 units
The correct answer is b = 6 √3 units
Answer:
b = 6
Step-by-step explanation:
The above questions is trigonometry where hypothenus = 12; opposite = b; and adjacent = a. Applying SOHCAHTOA principle, the appropriate is
Sine = opposite/hypothesis, since we are to find the value of b. Thus,
Sine 30 = b/12
0.5 =b/12
By cross multiplying,
b = 0.5 × 12
b = 6

A puppy finds a rawhide bone and begins to pull it with a force, Ft. The free-body diagram is shown. A free body diagram with 4 force vectors. The first vector is pointing downward, labeled F Subscript g Baseline = negative 8 N. The second vector is pointing right, labeled F Subscript t Baseline = 6 N. The third vector is pointing upward, labeled F Subscript N Baseline = 8 N. The fourth vector is pointing left, labeled F Subscript f Baseline = negative 4 N. The up and down vectors are the same length. The right vector is longer than the left vector. Which describes what happens to the bone? It begins to move toward the right. It stays in static equilibrium. It stays in dynamic equilibrium. It begins to move toward the left.
Answer:
It begins to move toward the rightExplanation:
The given information can be summarized in this way:
First force vector: Fg = - 8N (vertical down)Second force vector: Ft = 6N (horizonal right)Third force vector: FN = 8N (vertical up)Fourth vector: Ff = - 4N (horizontal left)Following Newton's second law, net force equal mass times acceleration:
Net force = mass × accelerationTo predict the motion, you apply Newton's second law in each direction (vertical and horizontal)
Vertical force balance:Net vertical force = 8N - 8N = 0. This means there is not motion in the vertical direction.
Horizontal force balance:Net horizontal force = 6N - 4N = 2N. This means there is a net force of 2N to the right, which lets you predict that the bone starts to accelerate to the right; this is, the bone begins to move toward the right.
Answer:
A. It begins to move toward the right.

The difference between two numbers is 9. The first number plus twice the other number is 27. Find the two numbers.
Answer:
The two numbers are 15 and 6.
Step-by-step explanation:
Given:
The difference between two numbers is 9.
The first number plus twice the other number is 27.
Now, to find the two numbers.
Let the first number be [tex]x.[/tex]
And the other number be [tex]y.[/tex]
So, the difference between two numbers is 9.
[tex]x-y=9[/tex]
[tex]x=9+y[/tex] ............(1)
As, given the first number plus twice the other number is 27.
According to question:
[tex]x+2y=27[/tex]
Substituting the value of [tex]x[/tex] from equation (1):
[tex](9+y)+2y=27\\9+y+2y=27\\9+3y=27[/tex]
Subtracting both sides by 9 we get:
[tex]3y=18[/tex]
Dividing both sides by 3 we get:
[tex]y=6.[/tex]
The other number = 6.
Now, substituting the value of [tex]y[/tex] in equation (1):
[tex]x=9+y\\x=9+6\\x=15.[/tex]
The first number = 15.
Therefore, the two numbers are 15 and 6.

For what value of the variable the value of the expression 4(5x–8) is 4 more than the value of the expression 2(4–x)?
The value of the expression 4(5x–8) is 4 more than the value of the expression 2(4–x) for x=2
Step-by-step explanation:
We have to write the given problem mathematically to solve it
So,
[tex]4(5x-8) = 2(4-x)+4[/tex]
First of all, distributive property will be applied
[tex]20x-32 = 8-2x+4\\20x-32 = 12-2x[/tex]
We have to isolate the variable on one side of the equation
Adding 2x on both sides of equation
[tex]20x-32+2x = 12-2x+2x\\22x-32 = 12[/tex]
Addition property of equality with 32
[tex]22x-32+32 = 12+32\\22x = 44[/tex]
Division Property of Equality (22)
[tex]\frac{22x}{22} = \frac{44}{22}\\x = 2[/tex]
Hence,
The value of the expression 4(5x–8) is 4 more than the value of the expression 2(4–x) for x=2

The sum of four consecutive even integers is 28
Answer:
The four consecutive even integers are 4, 6, 8 and 10.
Step-by-step explanation:
Let the four consecutive even integers be [tex]x, x+2, x+4, x+6[/tex]
It is provided that the sum of these consecutive even integers is 28.
Solve for x as follows:
[tex]x+ x+2+ x+4+ x+6=28\\4x+12=28\\4x=16\\x=4[/tex]
The four consecutive even integers are:
[tex]x=4\\x+2=4+2=6\\x+4 = 4 +4 =8\\x+6=4+6=10[/tex]
Thus, the four consecutive even integers are 4, 6, 8 and 10.
The Skittles jar has a radius of 3.5 cm and a height of 11.5 cm. Using the two given boxes for reference what would be a good estimate for the number of jelly beans in the jar?
Answer:
1052
Step-by-step explanation:
The two given boxes for reference are presented below.
Since we know the dimensions of the first container, we can calculate its volume.
[tex]V_1= 5 \text{cm} \cdot 4 \text{cm} \cdot 4 \text{cm} = 80 \text{cm}^3[/tex]
The first container held 192 skittles. Using that fact, now that we know the volume of the first box, we can calculate the volume of a single skittle.
[tex]v = \frac{80}{192} = 0.416 \approx 0.42 \text{cm}^3[/tex]
The second container held 258 skittles.
The volume of the second box is:
[tex]V_2 = 12 \text{cm}\cdot 3 \text{cm} \cdot 3 \text{cm} = 108 \text{cm}^3[/tex]
Using this facts, the volume of a single skittle would be
[tex]v = \frac{108}{258} = 0.418 \approx 0.42 \text{cm}^3[/tex]
Therefore, the volume of single skittle is around to 0.42 cm³.
A skittle jar is a cylinder. Its volume is calculated by the formula
[tex]V = r^2h \pi[/tex],
where [tex]r[/tex] is the radius and [tex]h[/tex] is the height. From the given data, we have [tex]r = 3.15 \text{cm}[/tex] and [tex]h = 11.5 \text{cm}[/tex]. Hence, the volume of the jar is
[tex]V = 3.5^2 \cdot 11.5 \cdot 3.14 = 442 \text{cm}^3[/tex]
Now, we can determine the number of skittles in the jar. Let [tex]n[/tex] be the number of skittles in the jar. Then,
[tex]n = \frac{\text{volume of the jar}}{\text{volume of a skittle}} = \frac{V}{v} = \frac{442}{0.42} = 1052.38 \approx 1052\\[/tex]
Final answer:
The best estimate for the number of jelly beans in the jar is approximately 1,000 beans, calculated based on linear dimensions and volume estimation.
Explanation:
The best estimate for the number of jelly beans in the jar would be approximately 1,000 beans.
To estimate this, we first look at linear dimensions and consider a rectangular jar. Assuming the jar is about 10 beans deep, 10 beans wide, and 10 beans high, the volume would be around 10 x 10 x 10, giving us ~ 1,000 beans inside.

9c − 10 = –10c − 10
The equation has only one solution, c = 0.
Explanation:To determine the number of solutions for the given equation, we need to solve it and see if there is a unique solution, infinitely many solutions, or no solution at all.
First, we can simplify the equation by combining like terms:
9c - 10 = -10c - 10
Adding 10c to both sides, we get:
19c - 10 = -10
