Answer:
Step-by-step explanation:
y = -4x + 7
perp. 1/4
y - 3 = 1/4(x + 8)
y - 3 = 1/4x + 2
y = 1/4x + 5
Answer:
6.45
Step-by-step explanation:
The answer=2.5*7.5-(2.75+9.55)=18.75-(12.3)=6.45
Answer:
54
Step-by-step explanation:
30,42,54,66,78
counting by 12
Fist, in the equation y=mx+b, b is the y-intercept. The y-intercept is the poin on the line that crosses the x-axis; the y-intercept is the value of yThese equations follow that format.
Y=mx+b
y

3x-4. <-----In this equation, the slope(m)=3 b= -4.
On the graph, we can see that the line crosses the x-axis at y=-4. Knowing that, we can eliminate the answer choices with +4 in the inequality.
The next step, is to pick an (x,y) coordinate that is in the shaded region and plug it into the remaining 2 inequalities. Which ever inequality is true after you solve it, that is the correct answer.
For example, I'll choose to plug in (-4,4) into the y

3x-4.
y

3x-4.
(4)

(3(-4))-4.
(4)

(-12)-4.
(4)

-16
So, this statement is true becasue -16 is less than positive 4. Therefore, the correct answer would be
y
3x-4. Hope that helped! Comment back with any further questions!
Answer:
8.6
Step-by-step explanation:
5.16 x 10 = 51.6 , 0.6 x 10 = 6, 6 divided by 51.6 = 8.6
