Answer:

The first three statements are correct, the other two are wrong

Second to last problem: WRONG - Since the second to last problem is marked down by 40% we subtract 40% from 100% to get 60%. Now we just do 0.60*28 = 16.8 which makes the statement wrong.

Last problem: WRONG - The last one is marked down by 50% so that is 100% - 50% to get 50%. We do 0.50 * 28 to get 14, making the statement wrong.

The first 3 statements are correct, and the 2 last ones are wrong

- Hope this helped! :)

Brainiest is most appreciated:)

A theorem in geometry states that the measure of an inscribed angle is half the measure of its

RoseWind [281]

Answer:

The first option is the correct option

Step-by-step explanation:

From the question the slope AC is evaluated as

$m_1 = \frac{b-0}{a- (-c)}$

$m_1 = \frac{b}{a+c}$

And the slope of line CB is mathematically evaluated as

$m_2 = \frac{0-b}{c-a}$

$m_2 = \frac{b}{c-a}$

Now for lines that are perpendicular to each other then the product of their slope should be equal to -1

So if $m ZC$ $= 90^o$

Then

$m_ *m_2 = -1$

i,e

$[\frac{b}{a+ c} ] [\frac{b}{a-c} ] = -1$

How can you tell that a system of linear equations will have infinitely many solutions without computation?

Contact [7]

If you can manipulate the two equations so that they have exactly the same coefficients (e. g., 3x + 4y = 8 and 2x + 4y = 8), then you conclude that the two lines coincide (overlap), and that there are thus infinitely many solutions.

What is the vertex of the graph of y + 2x + 3 = –(x + 2)2 + 1? (–3, –33) (–3, 3) (3, –24) (3, 21)

Arte-miy333 [17]

ANSWER

(-3,3)

EXPLANATION

The given function is

$y + 2x + 3 = - (x + 2) ^{2} + 1$

Expand

$y + 2x + 3 = - x ^{2} - 4x - 4 + 1$

Rewrite in the form:

$y =a {x}^{2} + bx + c$

This implies that,

$y = - x ^{2} - 4x - 2 x - 4 + 1 - 3$

$y = - {x}^{2} - 6x - 6$

Complete the square to get,

$y = - ( {x}^{2} + 6x) - 6$

$y = - ( {x}^{2} + 6x + {(3)}^{2} ) - - {(3)}^{2} - 6$

$y = - {(x + 3)}^{2} +9 - 6$

$y = - {(x + 3)}^{2} +3$

The function is now in the form:

$y = a {(x - h)}^{2} +k$

where (h,k) =(-3,3) is the vertex

The winner of the "Biggest Loser" lost 0.952 ounces per hour. Convert this to pounds per week. There are 16 ounces in one pound

stealth61 [152]

Answer: 10.0 lb/wk

Step-by-step explanation:

1. Calculate the number of days

1 week = 7 days

2. Convert days to hours

24 h = 1 days

No. of hours= 7 days* 24h/1 day= 168h

3. Convert hours to ounces

1h = 0.952 oz

No. of ounces= 168h* 0.952 oz/ 1h=159.9 oz

4. Convert ounces to pounds

1 lb = 16 oz

No. of hours= 7 days* 24h/1 day= 168h

Therefore the biggest loser lost 10.0 lb per week.

Please may I have brainliest?

stay safe!!!!!!!!
