Answer:

c

Step-by-step explanation:

160 = 16 * 10 =  4 * 4 * 2 * 5 = 2 * 2 * 2 * 2 * 2 *5

-4\sqrt{160} = -4\sqrt{2*2*2*2*2*5}\\\\= -4*2*2\sqrt{2*5}\\\\= -16\sqrt{10}

How would you graph the following systems of equations ? <br><br> y= -3x -7<br> x- 2y=-14
andrey2020 [161]
Solve both formulas to y=mx+b (slope intercept formula) where m=slope and b=y-intercept

y=-3/1x+-7

x-2y=-14
-2y=-14-x
y=7+1/2x

Start with the b variable so for problem 1 put a dot on 0,-7 and for problem 2 put a dot on 0,7

Then from -7 for problem 1 depending on whether the slope is negative or positive go down 3 and over right 1 therefore another point for problem one is marked, at 1,-10; for problem 2 up 1 and to the right 2; 2,8

For problem one connect the dots of 0,-7 and 1,-10

For problem two connect the dots of 0,7 and 2,8

Solve the following equation for x.<br>m (2-x)=3-y​
Evgesh-ka [11]

Answer:  m=−y+3−x+2

x=2m+y−3m

Step-by-step explanation:  

m(2−x)=3−y

Step 1: Factor out variable m.

m(−x+2)=−y+3

Step 2: Divide both sides by -x+2.

m(−x+2)−x+2=−y+3−x+2

m=−y+3−x+2

__________________________________________________

m(2−x)=3−y

Step 1: Add -2m to both sides.

−mx+2m+−2m=−y+3+−2m

−mx=−2m−y+3

Step 2: Divide both sides by -m.

−mx−m=−2m−y+3−m

x=2m+y−3m
