Answer:
y = 60 *x
Step-by-step explanation:
The rate is 180 miles / 3 hours = 60 miles per hour
Check by dividing 300 miles / 5 hours = 60 miles per hour
y = 60 *x where y is miles and x = time
Hey there!
For the left side, we are going to use the distributive property, which means:
a(b+c) = ab+ac
Therefore, we have:
4y + 8 = 32
Subtract 8 from both sides.
4y = 24
Divide both sides by 4 to get:
y = 6

Answer:
Line is y = -3x + 3
Slope = -3
y-intercept = 3
Step-by-step explanation:
Slope is the movement up or down, and left or right. Y-intercept is the point in which the line crosses the y-axis. In slope-intercept form (y=mx+b), m represents the slope, while b represents the y-intercept.
So since the line crosses the y-axis at positive 3, that will be the y-intercept. Now if we go from that very same point, and do rise/run, we'd move downwards 3 units and to the right 1 unit, to get our slope of -3/1 (it's written as just -3 though).
So now we plug it in: y = -3x + 3
Hope this helps you :)
Answer:
<h2>S.A. = 66m²</h2>
Step-by-step explanation:
Look at the picture.
We have :
4 rectangles 3m × 4m → A₁ = 3 · 4 = 12 m²
2 rectangles 3m × 3m → A₂ = 3 · 3 = 9 m²
Therefore the Surface Area of the rectangular prism is:
S.A. = 4A₁ + 2A₂
Substitute:
S.A. = 4(12) + 2(9) = 48 + 18 = 66
