Answer:
A
Step-by-step explanation:
A shift along the x-axis is the opposite in the graph than in the equation. Rather than the x-intercept(s) being negative if the equation is x - n, they become positive; likewise for the other way around. A is the only answer that follows this rule. However, the y-intercept is y = n, so if n is negative, y gets shifted down rather than up.
To the nearest foot, how many feet is the object in front of the whale? (image included)
[tex]\bf \begin{array}{ccll} feet&seconds\\ \cline{1-2} 4752&1\\ x&0.8 \end{array}\implies \cfrac{4752}{x}=\cfrac{1}{0.8}\implies 3801.6=x\implies \stackrel{\textit{rounded up}}{3802=x}[/tex]
so, we can conclude that since the wave went and came back in 0.8 seconds, it travelled the distance of 3802 feet, however that's the whole trip, we want to know how far the object is, and that'd be only the distance it took on its way forth, namely half the trip, namely 3802/2 = 1901.
Given: f(x) = x - 7 and h(x) = 2x + 3
Write the rule for h(f(x)).
h(f(x)) = 2x - 11
h(f(x)) = 2x - 7
h(f(x)) = 2x - 4
h(f(x)) = 3x - 4
Answer:
h(f(x)) = 2x - 11
Step-by-step explanation:
Answer:
h(f(x)) = 2x - 11 and the next one is f(h(x)) = 2x - 4 or A and B
If the area of a triangle is 18 units (squared 2 to the power), and a side of a triangle is 6, what is the other side?
Answer:
The other side is 6 units long.
Step-by-step explanation:
Area of a Triangle = (1/2)(Base)(Height)
18 = (1/2)(6)(x)
Note that x is the other side of the triangle.
18 = 3x
x = 6
The other side is 6 units long.

if it take 10 hours to get 50% how many hours are 32%
ANSWER
6.4 hours
EXPLANATION
if it takes 10 hours to get 50%, then it will take less number of hours to get 32%
We use proportion to solve this question.
If less more divides.
The number of hours it will take to get 32% is
[tex] = \frac{32\% \times 10}{50\%} [/tex]
[tex] = 6.4[/tex]
Hence it will take 6.4 hours to get 32%

A 5 inch × 7 inch photograph is placed inside a picture frame. Both the length and width of the frame are 2x inches larger than the width and length of the photograph. Which expression represents the perimeter of the frame?
Answer:
48in
Step-by-step explanation:
We know that the photograph is
Width photo = 5in
Lenght photo = 7in
The length and width of the frame are 2x inches larger than the width and frame of the photograph so:
Width frame = 5in x 2 = 10 in
Lenght frame = 7in x 2 = 14 in
The perimeter is the distance around a two-dimensional shape. Then, the perimeter of the frame is:
Perimeter = 10 in + 14 in + 10 in + 14 in = 48in
What is the base of the largest triangular flag can make?
Answer:
9.36cm
Step-by-step explanation:
We can add up all the sides to find the perimeter.
[tex]x+2x+2x=5x[/tex]
So the perimeter, 46.8, is equivalent to 5x.
Solve.
[tex]5x=46.8 \\ \\ x=9.36[/tex]
So [tex]x[/tex] is 9.36.
Since the base is [tex]1x[/tex], the base is 9.36cm.
We can plug back in to check our answers.
[tex]2x=18.72\\9.36+18.72+18.72 = 46.8[/tex]
The answer is 9.36cm hope u do well :)
A go-cart has a maximum weight limit of 240 pounds. Which inequality correctly represents this weight limit,w?
Answer:
w<240 pounds
Step-by-step explanation:
The inequality of weight is w≤250 pounds.
What is inequality?A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions
Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), larger than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
A go-cart has a maximum weight limit of 240 pounds.
let the weight is represented by 'w'
We can use inequality sign here as ≤.
Now, in the given situation weight should be less than or equal to 250 pounds.
Hence, the equality is w≤250 pounds.

27 Units
Please help and show work!!!!! Will mark brainliest!!!!!
Answer:
13 square units.
Step-by-step explanation:
We can find the area of the parallelogram using the formula:
[tex]Area=2\times \frac{1}{2}[|x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)|][/tex]
where [tex]A(x_1,y_1)[/tex], [tex]B(x_2,y_2)[/tex]. and [tex]C(x_3,y_3)[/tex] are the vertices of one of the triangles created by the diagonals.
[tex]Area=[|x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)|][/tex]
We use A(5, 3), B(8, 4), C(7, 8) to obtain:
[tex]Area=[|5(4-8)+8(8-3)+7(3-4)|][/tex]
[tex]Area=[|-20+40-7|][/tex]
[tex]Area=|13|=13[/tex]
The area of the parallelogram is 13 square units.
Write 7 over 10 as a percentage
70%
A percentage is the same thing as a fraction with a denominator of 100. To make our current denominator change to 100, we must multiply it by 10. So, we must do the same thing to the numerator. 7 times 10 is 70, and 10 times 10 is 100. This means 7/10 equals 70/100, which is 70%.
A 25ft ladder is placed 7 feet from the wall, as shown. How high up the wall with the ladder reach?
Answer:
24 ft up the wall
Step-by-step explanation:
We can use the Pythagorean theorem to solve, letting the 25 ft ladder be the hypotenuse
a^2 +b^2 = c^2
7^2 +b^2 = 25^2
49 + b^2 = 625
Subtract 49 from each side
49-49 +b^2 = 625-49
b^2 = 576
Take the square root of each side
sqrt(b^2) = sqrt(576)
b = 24
We only take the positive solution since length cannot be negative
The ladder will reach 24 ft up the wall
Consider the graph of the quadratic graph y=-x^2 -10x+24 ,what is the y-value of the vertex
-51
First, find the axis of symmetry, or the x value where the line switches directions. This is also the x value of the vertex. Find this by using the equation -b/2a. In this case, -10 is b, and 1 is a.
-(-10)/2(1)
10/2
5
So, the x value of the vertex is 5. Now, find the y value by putting the x value back into the equation.
y = -(5)^2 - 10(5) + 24
y = -25 - 50 + 24
y = -75 + 24
y = -51
So, the y value of the vertex is -51.

∠1 and ∠2 are complementary. If m∠1 = 4m∠2, find m∠1
Answer:
∠1 = 72°
Step-by-step explanation:
Complementary angles sum to 90°, thus
∠1 + ∠2 = 90, substitute ∠1 = 4∠2 , thus
4∠2 + ∠2 = 90
5∠2 = 90 ( divide both sides by 5 )
∠2 = 18°
Hence ∠1 = 90 - 18 = 72°
given a triangle with sides measuring 18 inches,21 inches 14 inches find the measure of the anglewith the greatest
ANSWER
[tex]A = 80.98 \degree[/tex]
EXPLANATION
The angle with the greatest measure corresponds to the longest:
Since we know the three side lengths, we use the cosine rule to obtain;
[tex] {a}^{2} = {b}^{2} + {c}^{2} - 2bc \cos(A) [/tex]
where a=21, b=18 and c=14
[tex] {21}^{2} = {18}^{2} + {14}^{2} - 2 \times 18 \times 14\cos(A) [/tex]
[tex]44 1= 324+ 196 - 504\cos(A) [/tex]
[tex]44 1= 520 - 504\cos(A) [/tex]
[tex]44 1 - 520 = - 504\cos(A) [/tex]
[tex] - 79 = - 504\cos(A) [/tex]
[tex]\cos(A) = 0.1567[/tex]
[tex]A = \cos ^{ - 1} (0.1567) = 80.98 \degree[/tex]

If the function rule is to add 6, and an output value is 6, what is the input value?
The answer is 0! The input value would be 0!
the function rule is to add 6, so:
y = x + 6 (y is the output, x is the input)
Since they gave you an output value of 6, you can plug it into the equation
y = x + 6 Plug in 6 for y
6 = x + 6 Subtract 6 on both sides to find the input value
0 = x

8x+2y=38
---------------------
15x/15=75/15
x=5
[4(5)+y=19]
y=-1
Final answer:
The solution to the given system of equations using elimination is x = 5 and y = -1. This was achieved by multiplying the second equation by 2 and then adding both equations to eliminate y.
Explanation:
We are given a system of linear equations and are asked to solve it using the method of elimination. We have the following equations:
1) 7x - 2y = 37
2) 4x + y = 19
To eliminate one of the variables, we can multiply the second equation by 2 to make the coefficient of y the same in both equations (but with opposite signs). After this step, our system looks like:
1) 7x - 2y = 37
2) 8x + 2y = 38
Now, adding the two equations will eliminate y, and we get:
7x + 8x = 37 + 38
15x = 75
x = 5
We can then substitute the value of x into one of the original equations to solve for y:
4x + y = 19
4(5) + y = 19
20 + y = 19
y = -1
So, the solution to the system is x = 5 and y = -1.
