2 answers:

7 0

Answer: -7/5 which is choice D

Explanation:

The term "zeros" refers to the x intercepts.

Plug in y = 0 and solve for x.

y = -5x-7

0 = -5x - 7

5x = -7

x = -7/5

The worlds two highest dams are both in Tajikistan. The rogue dam is 35 meters taller than the Nurek dam. together they are 635

galina1969 [7]

This is a sum and difference problem, with the equations
R-N=35
R+N=635
The solution of which is
R=(635+35)/2=335
N=(635-35)/2=300

In general, the sum and difference problem can be solved (most of the time mentally) using
Larger number = (sum + difference)/2
Smaller number = (sum - difference)/2

2 easy math questions!!!!!! Show work! Multiple choice!

elena55 [62]

Greetings!

<u>Question Seven:</u>
To find the slope given two points, we can use the slope formula:
$m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Input the points: (-11,5) (-6,1)
$m= \frac{1-5}{-6-(-11)}$

Simplify the equation:
$m= \frac{-4}{5}$

A parallel slope would be identical to this slope.

Therefore, the answer is B:
$\boxed{m_{2}= \frac{-4}{5}}$

-----------------------------------------------------------------------------------------------------------------

<u>Question Eight:</u>
This question essentially asks you to rearrange the equation into slope y-intercept form:
$y=mx+b$

Rearrange the equation:
$8x+7y=51$

$7y=-8x-51$

$y=\frac{-8x-51}{7}$

$y=\frac{-8}{7}x-\frac{51}{7}$

The slope (rate of change) is $\frac{-8}{7}$

Therefore the answer is F:
$\boxed{m=\frac{-8}{7} }$

I hope this helped!
