Answer:

the answers are d and b

Step-by-step explanation:

d. 19x - 18 = -19x + 18

38x - 18 = 18

38x = 36

x= 36/38= 18/19

b. 19x + 18= -19x + 18

38x + 18 = 18

38x = 0

x =0

Angles 1 and 2 are complementary, and angle 1=3x+3 and angle 2=10x-4, find the degree measure of each angle
tensa zangetsu [6.8K]

Answer:

The measure of the angles:

24°  and   66°

Step-by-step explanation:

Complementary angles sum 90°

then:

(3x + 3) + (10x-4) = 90

3x + 10x + 3 - 4 = 90

13x - 1 = 90

13x = 90+1

13x = 91

x = 91/13

x = 7°

then:

  • angle 1:

3x+3 = 3*7 + 3 = 21+3 = 24°

  • angle 2

10x - 4 = 10*7  - 4 = 70 - 4 = 66°

Check:

66° + 24° = 90°

Need help please don't know this no links
abruzzese [7]

Answer:

  $551

Step-by-step explanation:

The maximum profit is found where the derivative of the profit function is 0.

  y' = -2x +62 = 0

  x = 62/2 = 31

Then the maximum profit is ...

  y = (-x +62)x -410

  y = (-31 +62)(31) -410 = 961 -410 = 551

Assuming the profit is in dollars, the maximum profit the company can make is 551 dollars.

Y=2x+5 and y=3x+11 solve by substitution.
kondaur [170]

Answer:

Answer: x= -6 and y= -7

Step-by-step explanation:

Substitute 2x+5 for y in y=3x+11:

y=3x+11

2x+5=3x+11

2x+5+−3x=3x+11+−3x(Add -3x to both sides)

−x+5=11

−x+5+−5=11+−5(Add -5 to both sides)

−x=6

−x−1=6−1(Divide both sides by -1)

x=−6

Step: Substitute −6 for x in y=2x+5:

y=2x+5

y=(2)(−6)+5

y=−7(Simplify both sides of the equation)
