(0,3.75)(15,0)
slope(m) = (0 - 3.75) / (15 - 0) = -3.75/15 = - 0.25 or -1/4
y = mx + b
slope(m) = -1/4
(15,0)...x = 15 and y = 0
now we sub
0 = -1/4(15) + b
0 = -15/4 + b
15/4 = b
y = -1/4x + 15/4
1/4x + y = 15/4....multiply by 4
x + 4y = 15.....and since it is a solid line, it contains an equal sign...and since it is shaded above the line, it is greater.
so ur inequality is : x + 4y > = 15 (thats greater then or equal)
Answer:
5cm+6cm=11cm
Step-by-step explanation:
Adding the two,
Vertical angles are where the top equals the bottom or the left equals the right angle. So we would do:
8x - 13 = 5x + 8
And then substitute.
3x = 21
x = 7
Answer:
Linear, y=6x-21
Step-by-step explanation:
Graph the answer to get an idea of the shape: linear.
Use y=mx+b and m=y2-y1/x2-x1 to find formula
m=y2-y1/x2-x1=3-(-9)/4-2=12/2=6
y=6x+b
9=6(5)+b
9-30=b=-21
y=6x-21
