Answer:

StartFraction 7 over 2 EndFraction can be used to find the unit rate if one divides 7 by 2 and compares the result to 1

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

we have the points

B(2, 7) and D(4, 14)

substitute the values

The unit rate is

therefore

StartFraction 7 over 2 EndFraction can be used to find the unit rate if one divides 7 by 2 and compares the result to 1

When 5x^2 + 2= 4x is written in standard form, what are the values of a, b, and c
goblinko [34]

The standard form of a quadratic equation is

ax^{2}+bx+c=0,

where a, b, and c are coefficients. You want to get the given equation into this form. You can accomplish this by putting all the non-zero values on the left side on the equation.

In this case, the given equation is

5x^{2}+2=4x

Since 4x is on the right side of the equation, we subtract that from both sides. The resulting equation is

5x^{2}-4x+2=0

Looking at the standard form equation ax^{2}+bx+c=0, we can see that

a=5, b=-4, c=0

At noon, Bradley began steadily increasing the
barxatty [35]

Answer:

25.5 mph

Step-by-step explanation:

So Bradley's speed can be modeled by the equation y=2x+40 where y=speed, x=time in hours after noon, and b=initial speed

So 12:15 is 15 minutes after noon, which is also 0.25 or 1/4 of an hour after noon. This is the x-value. Plug this into the equation to get his speed at 12:15

y=2(0.25)+40

y=0.5+40

y=40.5

So his speed was 40.5 at the time and since he was going 15 miles over the speed limit, the speed limit is 15 less than his speed

40.5 - 15 = 25.5

Jake has two pet guinea pigs named fluffy and scruffy. Fluffy is8 1/8 inches long. Scruffy is 10 1/4 inches long. How much longe
miss Akunina [59]

Answer:

Scruffy is 2\frac{1}{8} inches longer than Fluffy.

Step-by-step explanation:

Length of Scruffy = 10\frac{1}{4} inches

Length of Fluffy = 8\frac{1}{8} inches

We have to calculate how much Scruffy is longer than Fluffy.

Difference of their lengths = 10\frac{1}{4}-8\frac{1}{8}

                                            = (10 - 8) + (\frac{1}{4}-\frac{1}{8})

                                            = 2 + (\frac{2-1}{8})

                                            = 2 + \frac{1}{8}

                                            = 2\frac{1}{8} inches

Therefore, Scruffy is 2\frac{1}{8} inches longer than Fluffy.
