Solve the following inequalities.
Airida [17]

1

-4x-2

Add 2 to both sides:

-4x

Divide both sides by -4 (this is negative, so we have to swap the inequality sign):

x>\dfrac{5}{2}

2

2(y-4)\leq 10-y

Expand the left hand side:

2y-8\leq 10-y

Add 8 and y to both sides:

3y\leq 18

Divide both sides by 3

y \leq 6

3-4

Nothing different from 1 and 2, apply the same logic (expand sides, gather constant and non-constant terms together, solve for the variable) and you will solve them

If q(x)=7x^2-1 find q(-9)
liq [111]

For this, we are just going to plug in -9 for every x and then solve the equation:


q(x)=7x^{2} -1


q(-9)=7(-9)^{2} -1


q(-9)=7(81)-1


q(-9)=566


Now we know that q(-9) is equal to 566.

At 55 mph it will take you approximately _____ feet to stop the car. A. 5 feet B. 100 feet C. 228 feet
ololo11 [35]

Answer:

The correct answer is option C, 228 feet

Step-by-step explanation:

As per Newton’s third law of motion:

V2 – U2 = 2 x a x S

Where V = final velocity

U = Initial Vlocity

a = acceleration (-ve)

S= distance travelled

V= 0 mph

U= 55 mph = 80.6667 ft /sec

0 – (80.6667 ft /sec)2 = 2 x (-g/2) x S

S = (80.6667 ft /sec)2 /(32.2 feet per second per second x0.5)

S = 202.1 feet

So the most nearest option is option C
