Answer:

No the answer is incorrect

Step-by-step explanation:

2*1.5-5=-1

3-5=-1

-2=-1

-1 and -2 are not the same

The correct answer is 2,5

Place the x (1.5) and y (5) values into the equation, and solve. If the statement you get is true, it is a solution.

2x - y = -1​

2(1.5) - 5 = -1​

3 - 5 = -1

-2 ≠ -1

Since this is a false statement, negative 2 is not equal to -1, the ordered pair is NOT a solution. I hope this helps and have a great day!

PLZ HELP SCALE FACTOR TRIANGLE<br><br> A. 10.5 cm<br> B. 31.5 cm<br> C. 63 cm<br> D. 189 cm
Anarel [89]

If two similar triangles have sides in the ratio a : b, then their areas are in the ratio a² : b².

We have the ratio:

54:18=\dfrac{54}{18}=3:1

Area of the smaler triangle = x

Area of the larger triangle = 567 cm²

Therefore we have the equation:

567:x=3^2:1^2\\\\\dfrac{567}{x}=\dfrac{9}{1}\qquad|\text{cross multiply}\\\\9x=567\qquad|\text{divide both sides by 9}\\\\x=63

<h3>Answer: C. 63 cm²</h3>

How do you write an equation of a line that is parallel line to y=8x-8 through the point (5,2)
Andreyy89
Parallel means that the two equations have the same slope,

so we have y = 8x + b so far.

Then we can just apply the slope to the given point by taking the y value and decreasing it by 40, due to the x value being 5

So in short, the equation that runs parallel to y = 8x-8 and intersect the point (5,2) is y = 8x -38

Y=-x+2 <br> y=-5x-6 <br> What is y and x
tatyana61 [14]
To solve this system of equations, since y is already isolated in both equations, you can set the expressions to equal each other to solve for x:

-x + 2 = - 5x - 6
-x + 5x = -6 - 2
4x = -8
x = -2

Now that we have x, we can substitute it into one of the equations to find y:

y = -(-2) + 2
y = 2 + 2
y = 4

The last step is to substitute both values into both equations to see if they are correct:

4 = -(-2) + 2    -->    4 = 2 + 2    <--True
4 = -5(-2) - 6    -->    4 = 10 - 6    <--True

Answer:
x = -2
y = 4
