Should it be facing left or right ?
riadik2000 [5.3K]

Answer:

Facing Right

Step-by-step explanation:

Given inequalities are:

4-x≤-1

Subtracting 4 from both sides

4-x-4≤-1-4

-x≤-5

Multiplying both sides with -1. Multiplying with a negative number changes the sign of the inequality

So,

x≥5

Second Inequality:

2+3x≥17

Subtracting 2 from both sides

2+3x-2≥17-2

3x≥15

Dividing both sides by 3

x≥5

Union of both solutions:

x≥5 ∩ x≥5

=> x≥5

Hence the solution will be facing right on the number line towards all numbers greater than or equals to 5 ..

Am I right ? Because I need help with this please thanks.
bazaltina [42]

to find the hypotenuse (or the ramp in question 4) you can use the equation

a^{2} +b^{2} =c^{2}

with a and b being the 3 feet and 9 feet and c being the unknown (ramp).

So if you plug 3 and 9 into the equation, it looks like this.

3^{2} +9^{2} =c^{2}

then square them.

9+81=c^{2}

simplify.

90=c^{2}

take the square root of both sides.

\sqrt{90} = c

\sqrt{90} is approx. 9.5 so the answer would be H.

If x = -1, what is the value of y in the equation?y = 8x3 + 12x2 - 6x - 3
Bezzdna [24]
<h3>Answer:   y = 7</h3>

Work Shown:

y = 8x^3 + 12x^2 - 6x - 3\\\\y = 8(-1)^3 + 12(-1)^2 - 6(-1) - 3\\\\y = 8(-1) + 12(1) - 6(-1) - 3\\\\y = -8 + 12 + 6 - 3\\\\y = 7\\\\

Explanation:

I replaced every x with -1. Then used the order of operations (PEMDAS) to simplify. Keep in mind that (-1)^2 = (-1)*(-1) = 1 and not (-1)^2 = -1
