 <span>(y + 9)(y - 2) = 0  would be the correct answer .</span>

For this case we have the following equation:


y ^ 2 + 7y = 18

Rewriting the equation we have:


y ^ 2 + 7y-18 = 0

Then, we must factor the equation:


We are looking for two numbers that are equal to 7 and multiplied equal to -18.


We have then:


(y + 9) (y-2) = 0

Answer:


An equation that could be used to solve y^2 + 7y = 18 by factoring is:


(y + 9) (y-2) = 0

Answer:

C

Step-by-step explanation:

We want to find the inverse of g(x). One way to do this is to switch the g(x) and x in the original equation and then solve for g(x); that will give you the inverse.

Here, g(x)=\frac{3}{5} x-9. Switch the g(x) and x to become: x=\frac{3}{5} g(x)-9. Now solve for g(x) by isolating it:

x=\frac{3}{5} g(x)-9

x+9=\frac{3}{5} g(x)

\frac{5}{3} * (x+9)= g(x)

g(x)=\frac{5}{3} x+15

Thus, the answer is C.

Hope this helps!

Joe and Josh each want to buy a video game. Joe has $14 and saves $10 a
Aleks [24]

Answer:

Number of week they have same amount = 4 week

Step-by-step explanation:

Given:

Amount Joe have = $14

Joe's saving per week = $10

Amount Josh have = $26

Josh saving per week = $7

Find:

Number of week they have same amount

Assume;

Number of week they have same amount = a

So,

(14 + 10a) = (26 + 7a)

3a = 12

a = 4

So,

Number of week they have same amount = 4 week

Hey can I have some help with this I am very confused
aniked [119]

#a

m<5=40°

  • Reason-Its Given

#b

m<2=140

  • Reason-Given

#c

<5 and <2 are linear pair(looked properly in diagram) Hence they are supplementary.

#d

<5 and 2 are same side interior angles (Clearly shown on diagram .

  • We can call them co responding interior angles and their sum will be 180 if lines are parallel

#e

a||b

Let's verify

Let the angle below <1 be <3

Now

<2+<3=180

<5+<4=180

  • <5=<2

\\ \sf\longmapsto

Hence verified

Enter an inequality that represents the graph in the box.
ANTONII [103]

The inequality that represents the graph in the box  is

y>-3x+6

Given :

The graph of the linear inequality

Lets pick two points from the graph to frame the linear equation

Slope intercept form of the equation is

y=mx+b

Where m is the slope and b is the y intercept

y intercept is (0,6) from the graph

so b=6

Now we find out slope m  using formula

Pick two points (0,6) and (2,0)

slope = \frac{y_2-y_1}{x_2-x_1} \\m=\frac{0-6}{2-0} =-3

m=-3

So the equation is y=-3x+6

Now we check the inequality sign by testing any point on shaded area

lets pick (4,0)

lets plug in 4 for x  and 0 for y

y=-3x+6\\0=-3(4)+6\\\\0=-6\\0>-6

The inequality for the given graph is

y>-3x+6

we cannot use >= sign because we have dotted lines
