Write the equation for the following graph (Hint: y= mx + b) Write the slope as a simplified fraction, not a decimal. Please Hel

Natali5045456 [20]

Answer:

y = (-5/2)x + 1

Step-by-step explanation:

We can see that the line intersects (0,1) and (2, -4). We use these points to find the slope: m = (-4-1)/(2-0) = -5/2. Also, the y-intercept is (0,1), so b = 1. Substituting these values into y=mx +b, we get y = (-5/2)x + 1.

I hope this helps! :)

Kala drove 250 miles using 9 gallons of gas. at this rate how many gallons of gas would she need to drive 275 miles

Rus_ich [418]

Answer:

9.9 gallons

Step-by-step explanation:

To solve this problem, we need to cross multiply. Lets input the values (250, 275, 9) as shown below:

$\frac{9}{250} = \frac{x}{275}$

Next we cross multiply. We multiply 250 and x, and we multiply 9 and 275.

$250(x) = 250x\\$

$275(9) = 2,475$

Now, lets put the values above back into the equation:

$250x = 2,475$

Lets solve this equation. First we divide 2,475 by 250, making x by itself.

$\frac{2,475}{250} =x$

$9.9 = x$

This means that to drive 275 miles, Kala would need to use 9.9 gallons of gas.

(x + 7)^2 – 11 = 0<br> lesser =<br> greater =

Andreyy89

Answer:

Lesser = - $\sqrt{11}$ - 7 = -10.317

Greater = + $\sqrt{11}$ - 7 = -3.683

Step-by-step explanation:

I am assuming you are asking for the lesser x solution and greater x solution.

(x + 7)^2 – 11 = 0

(x + 7)^2 = 11

x+7 = ± $\sqrt{11}$

x = ± $\sqrt{11}$ - 7

Lesser = - $\sqrt{11}$ - 7 = -10.317

Greater = + $\sqrt{11}$ - 7 = -3.683
