What is the slope plz help plz

Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

To find slope you need to take two points from the line and use the slope formula ( $m = \frac{\text{rise}}{\text{run}} = (y_2 - y_1)/(x_2 - x_1)$ )

Im going to take the points (0,3) and (-2,3) So now lets put these coordinates into the formula:

$(3 - 3)/(-2 - 0)$

this would give us 0

(Edit* tbh i think the line might not even exist - ya know it says ¨Find the slope of the line if it exists¨ anyway ~_~ hope this helped...!)

Answer 2

Answer:

Answer:

Slope m=-5/3

Step-by-step explanation:

Slope is m =(y2-y1)/(x2-x1)

You need to use two points

(x1,y1)= (0,3)

(x2,y2)= (3,-2)

m=(-2-3)/(3-0) = -5/3

Answer:idk

Step-by-step explanation:

Answer:

9x > 18

Step-by-step explanation:

Answer:

(i) x<3

(ii) x > 2

Step-by-step explanation:

4x - 4 < 8

Add 4 to both sides of the equation , that is

4x - 4 + 4 < 8 + 4

4x < 12

divide through by 4

x<3

Also

9x + 5 > 23

subtract 5 from both sides , that is

9x > 18

x > 2

Benito spent $1837 to operate his car last year. Some of these expenses are listed below. Benito's only other expense was for gasoline. If he drove 7600 miles, what was the average cost of the gasoline per mile?

Answers

Operating Expenses
Cost Insurance $972
Registration $114
Maintenance $105

1837 - 972 - 114 - 105 = 646 cost of gasoline

646 / 7600 = 0.085 or 8.5 centavos

Answer:

8.5 Cent

Unknown g (x) = ax + b and g (g (x)) = 16x - 15. Calculate the value of a and b.

Answers

g(g(x))=16x-15
means that when you subsituted g(x) for x in g(x), you got 16x-15

a(ax+b)+b=16x-15
distribute
xa^2+ab+b=16x-15d
we look at the x terms
therefor
xa^2=16x
a^2=16
a=-4 or 4
we will find out

look a constant terms
ab+b=-15
undistribute b
b(a+1)=-15

if a is -4 then
b(-4+1)=-15
b(-3)=-15
b=5

if a=4 then
b(4+1)=-15
b(5)=-15
b=-3

so
g(x)=-4x+5 or
g(x)=4x-3

if a=-4, b=5
if a=4, b=-3
