Answer:
First quadrant will the line not pass.Step-by-step explanation:
The given line has a negative slope. It means with increasing value of x, y will be decreasing. It has a negative y-intercept that is at x = 0, y is less than 0.
If the value of x will be greater than 0, the value of y will be going downwards continuously.
If x > 0, y < 0, as the line has a negative y-intercept.
A point in first quadrant means x > 0 as well as y > 0.
Hence, the line cannot pass through the first quadrant.
A line with a negative slope and a negative y-intercept will not pass through Quadrant I.
A line with a negative slope indicates that as the x-value increases, the y-value decreases. A negative y-intercept means that the line intersects the y-axis below the origin.
Quadrant I is the region of the coordinate plane where both x and y are positive. Since the line has a negative slope and a negative y-intercept, it will not intersect Quadrant I.
As the x-value increases in Quadrant I, both x and y will be positive, which contradicts the line's negative slope. Additionally, the line's negative y-intercept places it below the x-axis, further preventing it from intersecting Quadrant I.
Therefore, the line will pass through Quadrants II, III, and IV, but not Quadrant I.

what is 3y+14-2=0 in substitution
Answer:
y=-4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3y+14−2=0
3y+14+(−2)=0
(3y)+(14+(−2))=0 (Combine Like Terms)
3y+12=0
3y+12=0
Step 2: Subtract 12 from both sides.
3y+12−12=0−12
3y=−12
Step 3: Divide both sides by 3.
3y/3= −12/3
y=−4
Answer:

the perimeter of a square is 66.8 cm. What is the side lengh of the square
Side length = 16.7 cm
Solution:
Perimeter of a square given = 66.8 cm
In a square four sides are equal.
The perimeter of a square = 4 × side
⇒ 4 × side = 66.8 cm
Divide both sides of the equation by 4 to equal the expression.
⇒ side = 66.8 ÷ 4
⇒ side = [tex]\frac{66.8}{4}[/tex]
⇒ side = 16.7 cm
Hence, the side length of the square is 16.7 cm.

m=(2-(-4))/(-1-0)
m=(2+4)/(-1)
m=6/-1
m=-6
the answer is B, -6, because if you graph it the line goes down and it rises up 6
Line V has a slope of 8/9. Line w is perpendicular to V. What is the slope of line W?
Answer:
W = -9/8
Step-by-step explanation:
for two perpendicular lines
W*V = -1
W = 9/8*(-1)
W= -9/8
Final answer:
The slope of line W, which is perpendicular to line V with a slope of 8/9, is -9/8.
Explanation:
The slope of a line perpendicular to another in a two-dimensional plane is the negative reciprocal of the original line’s slope. Given that line V has a slope of 8/9, the slope of the perpendicular line W would be -9/8. This is because the product of the slopes of two perpendicular lines is -1 (negative one). Therefore, the slope of the line W, which is perpendicular to V, is -9/8.

26.35 rounded to the nearest hundred
Answer:
Nearest hundred: 0
Nearest hundredth: 26.35
Step-by-step explanation:
The hundred place value is three numbers to the left of the dot.
The two hundreds that are nearest to 26.35 are 0 and 100. To decide if you should round up (to 100) or round down (to 0), use the place value that is to the right of the hundred place: the number you are using is 2.
The rule for rounding:
Round up if the place value is 5 or more
Round down if the place value is 4 or less
Since 2 is "4 or less", round down to 0.
Since 26.35 is closer to 0 than 100:
26.35 => 0 when rounded to the nearest hundred
In case you meant hundredth:
The nearest hundredth means two decimal places, or two numbers right of the dot.
The number 26.35 already has two decimal places, so rounded to the nearest hundredth is still 26.35.
26.35 => 26.35

15x-4y=62

Answer:
y = 7 and x = 6
Step-by-step explanation:
15x-4y=62 ---------------------------(i)
5x+8y=86-----------------------------(ii) X 3
15x+24y=258---------------------------(iii)
(iii)-(i)
28y = 196
y = 7
Sub. for y in (I) to get x
x = 6
Final answer:
The system of equations 15x - 4y = 62 and 5x + 8y = 86 is solved using the method of elimination, yielding the solution x = 6 and y = 7.
Explanation:
We are asked to solve a system of equations:
15x - 4y = 625x + 8y = 86We will use the method of elimination to solve this system, which involves manipulating the equations so that adding or subtracting them will eliminate one of the variables, allowing us to solve for the other.
Multiply the second equation by 3: 15x + 24y = 258.Subtract the first equation from the modified second equation: 15x + 24y - (15x - 4y) = 258 - 62.This gives us 28y = 196, and solving for y gives us y = 7.Substitute y = 7 into the first original equation to find x: 15x - 4(7) = 62.Solve for x: 15x - 28 = 62, which gives x = 6.Therefore, the solution to the system of equations is x = 6 and y = 7.

10 minus three times a number is no more than 61
Answer:
n ≥ -17
Step-by-step explanation:
Writing a symbolic inequality, we get:
10 - 3n ≤ 61
Solve this for 3n by adding 3n to both sides of this equation:
10 ≤ 61 + 3n
Solve for n by subtracting 61 from both sides and then dividing all of the resulting terms by 3:
-51 ≤ 3n (divide both sides by 3):
-17 ≤ n, or
n ≥ -17

A) A 90 degree counterclockwise rotation about the origin followed by a translation 1 unit to the left
Step-by-step explanation:
The formula to do a 90 degree counterclockwise rotation is (x, y) to (y, -x) so if the ordered pair is (5, 3) and you were to rotate it counterclockwise it would be (3, -5). Once you do this to all of the values, you are one unit to the right of what you should be, so then you would have to translate it 1 to the left in order to match up both of the trapezoids.

Answer:
ok so im going give the equation to fiqure this along with the awnser,
the basic equation is A=P (1+R/N)N(T)
P= Principle (Starting amount)
R= Interest rate
N= Amount of time compounded PER YEAR
T= amount of years
Step-by-step explanation:
so this would be A=$7500 (1+ 0.055/12)12(3)
which come to A=$7500 (1.178948602)
which comes to a total of $8842.11
hope this helps
Final answer:
The balance of a savings account with an initial deposit of $7500 and an annual interest rate of 5.5%, compounded monthly, will be approximately $8863.52 after 3 years.
Explanation:
The question involves the concept of compound interest, more specifically how much the balance of a savings account with an initial deposit of $7500 and an annual interest rate of 5.5%, compounded monthly, will be in 3 years. To calculate this, we use the compound interest formula: A = P(1 + r/n)^(nt), where:
A = the amount of money accumulated after n years, including interest.P = the principal amount (the initial amount of money).r = the annual interest rate (decimal).n = the number of times that interest is compounded per year.t = the time the money is invested for, in years.For the given problem:
P = $7500r = 5.5% or 0.055 (as a decimal)n = 12 (since it's compounded monthly)t = 3 yearsWe can substitute the values into the formula:
A = 7500(1 + 0.055/12)^(12*3)
Calculating this out, we find:
A = 7500(1 + 0.0045833)³⁶
A = 7500(1.0045833)³⁶
A = 7500(1.1811360235)
A = $8863.52 (approximately)
Therefore, the approximate balance of the savings account after 3 years will be $8863.52.

$8.00. If five have hamburgers and two have hot dogs,
the bill will be $9.50. What is the price of a hamburger?
Answer:
1.50$
Step-by-step explanation:
2 hamburgers would equal 3$ and if the hot dogs are 1$ each it woul make the equation true
To find the price of a hamburger, set up a system of equations and solve for the price using the given information. So, the price of a hamburger is $2.50
Explanation:To find the price of a hamburger, we can set up a system of equations based on the given information.
Let x be the price of a hamburger.
From the first scenario, we have 2x + 5(0.50) = 8.00.
From the second scenario, we have 5x + 2(0.50) = 9.50.
Simplifying these equations gives us 2x + 2.50 = 8.00 and 5x + 1.00 = 9.50.
Solving these equations, we find that x = $2.50.
Therefore, the price of a hamburger is $2.50.

The endpoints of cd are C (-4,10) and D (-4,10) the coordinates of the midpoint M of CD are
The endpoints C and D has no midpoint M.
Step-by-step explanation:
step 1: The given endpoints of C and D are (-4,10) and (-4,10)
step 2: Midpoint formula = ((x1+x2)/2 , (y1+y2)/2)
step 3: Here, C(-4,10) = (x1,y1)
D(-4,10) = (x2,y2)
step 4: The midpoint represents the half distance of the line CD. Since C and D are same points, they cannot form a line. Therefore, the endpoints CD have no midpoint.
