Answer:

x= 102 degrees

Step-by-step explanation:

It is an isosceles triangle, which means that it has two equal sides and angles, so the angles opposite of 3.3 are going to be the same or 39 degrees, which means, 39 + 39 is 78 and 180 - 78 is 102 and x=102 degrees.

Look at the picture and solve the equations
ch4aika [34]

Answer:

1. a= 7, one solution

2. x=x, infinitely solutions

3. y=3, one solution

4. x=6, one solution

5. no solution

6. k = 2, one solution

Step-by-step explanation:

1.

7a - 6 = 43

7a = 49

one solution

a = 7

2.

3x + 4 = 3x + 4

3x = 3x

x = x

infinitely solutions

3.

4(2y - 4) = 5y + 2

8y - 16 = 5y + 2

3y -16 = 2

3y = 18

one solution

y= 6

4.

multiply 2 on both sides

5x + 6 = x + 30

4x = 24

one solution

x = 6

5.

4e - 19 = 4(e-4)

4e - 19 = 4e -16

-19 ≠ -16

no solution

6.

10k - 2(k+3) = 10

10k -2k - 6 = 10

8k - 6 = 10

8k = 16

one solution

k = 2

The function f(x) = –x2 − 2x + 15 is shown on the graph. What are the domain and range of the function?
Makovka662 [10]
The function is a parabola which opens downwards.
-x^2 - 2x + 15
-(x^2 + 2x) + 15
= -[(x + 1)^2 - 1 ]+ 15
= -(x + 1)^2 + 16

The domain is all real numbers and the range is {y|y <= 16}
Its the second choice.
