Answer:

2x⁴ + 2x + 10

Step-by-step explanation:

Step 1: Write out expression

-7x - 5x⁴ + 5 + 7x⁴ + 5 + 9x

Step 2: Combine like terms (x⁴)

2x⁴ - 7x + 5 + 5 + 9x

Step 3: Combine like terms (x)

2x⁴ + 2x + 5 + 5

Step 4: Combine like terms (constants)

2x⁴ + 2x + 10

Given that <span>For a certain model of car the distance $d$ required to stop the vehicle if it is traveling at $v$ mi/h is given by the formula $d=v+\frac{v^2}{20}, where [tex]d$ is measured in feet.

If Kerry wants her stopping distance not to exceed 75 ft, then the range of speeds (in mi/h) can she travel is obtained as follows:

$v+ \frac{v^2}{20} \leq75 \\ \\ 20v+v^2\leq1,500 \\ \\ v^2+20v+100\leq1,500+100 \\ \\ (v+10)^2\leq1,600 \\ \\ |v+10|\leq\sqrt{1,600} \\ \\ -40\leq v+10\leq40 \\ \\ -40-10\leqv\leq v\leq40-10 \\ \\ -50\leq v\leq30$

Therefore, the range of speed she can travel is $v\leq30\ mi/hr$

ANSWER PLEASE 40 POINTS!

tangare [24]

Answer: |10 - (-8)|

The absolute value is 18

Step-by-step explanation:

The distance between two numbers is a subtraction equation.

10 - (-8) Subtracting a negative is like adding a positive

10 + 8 = 18

If you look at it as the first negative sign means -1 multiplied by the next negative number, "Remember that a negative times a negative is a positive!"
