Please help urgent 168 ≥7(-8x+8)

Mathematics
1 answer:
zhuklara [117]3 years ago

Answer:

\boxed {x \geq -2}

Step-by-step explanation:

Solve for the following inequality:

168 \geq 7(-8x + 8)

-Divide both sides by 7:

\frac{168}{7} \geq -8x + 8

24 \geq -8x + 8

-Switch sides:

24 \geq -8x + 8

-8x + 8 \leq 24

-Subtract 8 to both sides:

-8x + 8 - 8 \leq 24 - 8

-8x \leq 16

-When you are dividing an integer by a <u>negative</u> integer, then the inequality sign changes. So, divide both sides by -8:

\frac{-8x}{-8} \leq  \frac{16}{-8}

\boxed {x \geq -2}

vampirchik [111]

Answer:

x = -4.59, -7.41.

Step-by-step explanation:

x^2 + 12x + 34 = 0

(x + 6)^2 - 36 +34 = 0

(x + 6)^2 = 36 - 34 = 2

x + 6 = +/-√2

x =   +/-√2 - 6

x = -4.59, -7.41

alex41 [277]
GIVEN:
total length of the banner = 30 ft.
perimeter of the banner = 96 ft.
total width of the rectangle = ?
Let,
the perimeter be "p"
the length be "L"
the width be "w"
We know,
Perimeter (P) of a rectangle = 2 (L + w) 
Substituting the values of P, L and w , we get,
                                      96  = 2 (30 + w)  
                                  96 / 2 = 30 + w
                                       48 = 30 + w
                                48 - 30 = w
                                       18 = w

So, the width of the rectangular banner is 18 ft.
