Mathematics

Answer:

x =   - \frac{9}{2}

Step-by-step explanation:

1) Add 5 to both sides.

- 2x = 4 + 5

2) Simplify 4 + 5 to 9.

- 2x = 9

3) Divide both sides by -2 to get the answer.

x =  -  \frac{9}{2}

hence, the answer is x = -9/2.

Write an equation in slope Intercept form for the line with slope
aivan3 [116]

Answer:

y= \frac{2}{5}x -3

Step-by-step explanation:

slope-intercept form is y=mx+b

m= slope

b= y-intercept

so plugin your numbers with the given data...

and you get y=2/5x-3

For the graph, you start at -3 on the <u>y-intercept</u> and then <em>move right 5</em> and<em> up 2</em>

Graph is the picture below :)

Please answer correctly !!!!!!! Will mark brainliest
Sauron [17]

Answer:

option 1

Step-by-step explanation:

y = 3x + 3   ie       3x -y +3 =0     a1= 3  , b1=-1  ,  c1=3

y = -2x + 3   ie      -2x -y+3 = 0    a2=-2 , b2=-1 , c2=3

on comparing the ratios ,

a1/a2 = 3/2

b1/b2 = -1/-1= 1/1 =1/1= 1

a1/a2 ≠ b1/b2

therefore the pair of linear equations will have exactly one solution

mark me as the brainliest...

Find the average rate of change between f(-7) and f(-1) in the function f(x)=x^2+2x -8
Viktor [21]

Solve the equation by replacing x with -7 and then -1.

Then subtract the two to find the difference and divide that by the difference between -7 and -1.

f(-7) = -7^2 + 2(-7) -8 = 49 -14 -8 = 27

f(-1) = -1^2 + 2(-1) -8 = 1 -2 - 8 = -9

Difference between 27 and -9 = -36

Difference between -1 and -7 = -6

Rate of change = -36 /-6 = 6
