Answer:

Step-by-step explanation:

(a)  27 degrees:  <em>complementary angle</em> is (90 - 27) degrees, or 63 degrees; recall that complementary angles add up to 90 degrees.  

(b)  Since supplementary angles add up to 180 degrees, we subtract 105 degrees from 180 degrees, obtaining the supplementary angle 75 degrees.  There's <em>no complementary angle here</em>, because 105 degrees is greater than 90 degrees.

(c) <em>complementary angle is (90 - 18) degrees, or 72 degrees</em>; <em>supplementary angle is (180 - 18) degrees, or 162 degrees</em>.

4x^2-400=0<br><br> square roots and solving quadratics
posledela

Answer:

x = ±10

Step-by-step explanation:

4x² - 400 = 0

Add 400 to both sides

4x² = 400

Divide both sides by 4

x² = 100

Take the square root of both sides

x = ±10

Write an<br> equation of a line that passes through each pair of points.<br> (-2,6) (0,0)
arlik [135]
Answer: y= -3x

(there is no y-intercept in the points you listed so if you can find one on a picture of your question, do so. but since i do not see a given y-intercept, i assume it is 0)

To find the slope, use the two points given.

1st: subtract the y-values. 0-6= -6.

2nd: subtract the x-values. 0-(-2)= 2

3rd: you have -6/2.

4th: simplify to get a slope of -3.

Two teams are selling candy bars to raise money. Team A has $165 saved and they are selling each candy bar for $2. Team B has $7
devlian [24]

Answer: Each have to sell 91 candy bars to have the same amount of money.

Step-by-step explanation: Suppose x represents the amount of candy bars.

Team A already have $165 and they are selling each candy bar for $2. The mathematical equation that represents the amount of money they have is

A: 165 + 2x

Team B initially has $74 and will sell each candy bar for $3. Then, the mathematical equation representing their amount of money is

B: 74 + 3x

So, to have the same amount of money:

165 + 2x = 74 + 3x

x = 165 - 74

x = 91

<u>Teams A and B will have the same amount of money when each of them </u><u>sell 91 candy bars</u>.
