Solve for x, which can be done by moving x to the other side.
2(x-5)^2+8

So, x = 5

The y value is the number at the end and we can see that it is positive 8.

y = 8

Write it out as a coordinate pair and you would get (5,8) or answer choice D

Broccoli costs $ 1.50 per pound at a grocery store. How much money does 64 ounces of broccoli cost, before tax?

Ber [7]

Note that 1lb=16oz and set up multiplication/division to cancel out units that you do not need for the final answer. (Units cancel just like numbers, this is fundamental to dimensional analysis)

64oz($1.50/16oz)=$6.00

Solve for w. | – w|≥2 Write a compound inequality like 1 < x < 3 or like x < 1 or x > 3. Use integers, proper fracti

Eduardwww [97]

Answer:

$-2 \geq w \geq 2$

Step-by-step explanation:

Given

$|-w| \geq 2$

Required

Solve for w

$|-w| \geq 2$

In absolution functions;

$|-w| = |w|$

So, the given expression can be rewritten as

$|w| \geq 2$

Removing the absolute sign, will gibe

$w \geq 2$ or $w \leq -2$

When the second inequality os rewritten, it gives

$w \geq 2$ or $-2 \geq w$

Reorder both inequalities

$-2 \geq w$ or $w \geq 2$

Lastly, both inequalities are combined

$-2 \geq w \geq 2$

(y+3):(y+5)=k:1<br><br> show that y=(5k-3)/(1-k)<br><br> hence y=(5k-2)/(1-k)

luda_lava [24]

hi,

Express the ratios in fractional form, that is

= ( cross- multiply )

y + 3 = k(y + 5) ← distribute

y + 3 = ky + 5k ( subtract ky from both sides )

y - ky + 3 = 5k ( subtract 3 from both sides )

y - ky = 5k - 3 ← factor out y from each term on the left side

y(1 - k) = 5k - 3 ← divide both sides by (1 - k)

y = 5k- 3

____

1 - k
