Answer:

m = $\frac{-9}{13}$

Step-by-step explanation:

I'm assuming by m, you mean the slope.

You have two points. (-11, 5) and (2, -4)

m = change in y-value ÷ change in x-value

1) Substitute in the points.

m = $\frac{(-4)- 5}{2 - (-11)}$

2) Solve.

-4 - 5 = -9

2 - (-11) = 13

So, the slope would equal $\frac{-9}{13}$ .

Answer:

225

Step-by-step explanation:

60 x 3 = 180 ($60 for each charity and there's 3 charities)

180 / (4/5) = 225 (if $180 is four fifths of his total just divide 180 by 4/5 to get the answer)

XYZ has coordinates X(2, 3), Y(1,4), and Z(8,9). A translation maps X to X'(4,7). What are the coordinates for Y' and Z' for thi

Rashid [163]

Answer:

The coordinates are $Y'(x,y) = (3, 8)$ and $Z'(x,y) = (10, 13)$ .

Step-by-step explanation:

First, we have to derive an expression for translation under the assumption that each point of XYZ experiments the same translation. Vectorially speaking, translation from X to X' is defined by:

$X'(x,y) = X(x,y) + T(x,y)$ (1)

Where $T(x,y)$ is the vector translation.

If we know that $X(x,y) = (2,3)$ and $X'(x,y) = (4,7)$ , then the vector translation is:

$T(x,y) = X'(x,y)-X(x,y)$

$T(x,y) = (4,7) - (2,3)$

$T(x,y) = (2, 4)$

Then, we determine the coordinates for Y' and Z':

$Y'(x,y) = Y(x,y) + T(x,y)$

$Y'(x,y) = (1,4) + (2,4)$

$Y'(x,y) = (3, 8)$

$Z'(x,y) = Z(x,y) + T(x,y)$

$Z'(x,y) =(8,9) + (2,4)$

$Z'(x,y) = (10, 13)$

The coordinates are $Y'(x,y) = (3, 8)$ and $Z'(x,y) = (10, 13)$ .

FOR BRAINLIEST Express 0.64 as a fraction in lowest terms. 5/32 64/10 16/25 4/5

Nadusha1986 [10]

Answer:In its decimal form, it says ' 64 / 100 '.

In order to change it to its lowest terms, we look to see whether the

numerator and denominator have a common factor greater than ' 1 '.

If they do, then we can divide numerator and denominator by their

common factor, and have the same fraction in lower terms.

The common factors of 64 and 100 are 1, 2, and 4 .

We could divide top and bottom by 2, but that wouldn't finish the job.

It's always best to divide them by their greatest common factor, and

once you do that, you're done.

Dividing the numerator and denominator both by 4,

we get the fraction in its lowest terms:

0.64 = 64/100 = 16/25

-3x + 4y = 12; 3x - 5y = 18 Solve

viktelen [127]

X = -44
y = -30

Solve for y in equation 1.
Plug in the new value for y into equation 2 to solve for x.
Next, plug your x value into either equation to find y. You can choose either, but I picked the 1st equation.
