The graphs below have the same shape. What is the equation of the red graph?

We claim that the answer is $y=-x^2.$ Since the two graphs both open down, and all the answer choices, in addition to the equation of the blue graph, are quadratic polynomials, the leading coefficient must be negative. This immediately rules out answer choices A, B, and C, leaving D as the answer.

Classify each pair of labeled angles of a complementary, supplementary, or neither.

Vsevolod [243]

Answer:

The first one is neither: 90+89=179

The second one could be either supplementary or neither: 63+47=110, but if you add the final angle measure it would be 180

The last one is complementary: 62+29=90

At a local amusement park, 70% of the rides are made for kids who are 48 inches and taller. If there are 80 rides in total, how

Musya8 [376]

Answer:

56

Step-by-step explanation:

Basically you want to find out what is 70% of 80.

first you have to set up your problem

$\frac{n}{80}$ = $\frac{70}{100}$

the first fraction would be the percent (70) over 100. (you always use 100)

The fraction to the left would be n over 80. the denominator (the number on the bottom) would be the whole amount. n would be the unknown number

To solve you would use the butterfly method. 80 x 70 and 100 x n. 80 x 70 is 5600 and 100 x n is 100n.

The final step is dividing. 5600 divided by 100 giving you 56

Write an equation of the line that passes through (2, -3) and is perpendicular to the line y=-2x-3

Natalija [7]

Answer:

$y=\frac{1}{2} (x-2)-3$ or $y=\frac{1}{2} x-4$

Step-by-step explanation:

The perpendicular slope is the opposite-reciprocal of the original slope:

Perpendicular slope of -2 is $\frac{1}{2}$

Write the equation in point-slope form ( $y=a(x-h)+k$ ):

$y=\frac{1}{2} (x-2)-3$

Convert to slope-intercept form if needed:

$y=\frac{1}{2} x-1-3$

$y=\frac{1}{2} x-4$
