Answer:

r =5 miles per hour

Step-by-step explanation:

rt = d

We want to solve for r

Divide each side by t

rt/t = d/t

r = d/t

We know the distance is 7.5 miles and the time is 1.5 hours

r = 7.5 miles / 1/5 hours

r =5 miles per hour

Answer:

The rate is 5 miles per hour

Step-by-step explanation:

First thing off we need to get r alone. We can do this by dividing both sides by t. Lets do so

rt/t=d/t

Simplfy

r=d/t

Now input the known value for d and t

r=7.5/1.5

Divide

r=5

The rate is 5 miles per hour

What is the function rule represented by the following table?
Romashka-Z-Leto [24]

Answer:

y=-4x+3

Step-by-step explanation:

as x=0

put in y= -4x+3

y= -4(0)+3

y=3

now put x=1 in y= -4x+3

y= -4(1)+3

y= -1

now put x=2 in y= -4x+3

y= -4(2)+3

y=-5

Which shows the correct substitution of the values a, b, and c from the equation 0 = 4x2 + 2x – 1 into the quadratic formula bel
lidiya [134]
0 = 4x²<span> + 2x – 1

this equation is already ordered by degree, so it's in the correct form. the standard form of a parabola is like so: 0 = A</span>x² + Bx - C

that's exactly how you plug values into the quadratic formula. the coefficient for your squared value, A, is 4. take the coefficients from your other numbers as well.

a = 4
b = 2
c = -1

Given the following graph what is the slope?
balandron [24]

Answer:

slope = \frac{1}{4}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 4, 1) and (x₂, y₂ ) = (0, 2) ← 2 points on the line

m = \frac{2-1}{0-(-4)} = \frac{1}{0+4} = \frac{1}{4}
