Can someone help?<br> Need to find x, and measure of angle DEF
Colt1911 [192]

Answer:

x = 5

m\angle DEF = 90\degree

Step-by-step explanation:

GE is the angle bisector of quadrilateral DEFG,

Thus, by angle bisector property:

9x°= (5x + 20)°

9x = 5x + 20

9x - 5x = 20

4x = 20

x = 20/4

x = 5

m\angle DEF = 9x\degree + (5x+20)\degree

m\angle DEF = (14x+20)\degree

m\angle DEF = (14\times 5+20)\degree

m\angle DEF = (70+20)\degree

m\angle DEF = 90\degree

Answer:

C. The rate of change of Function 1 is the same as Function 2.

Step-by-step explanation:

The rate of change in an equation is the slope. In this case, function 1's slope is 1/2 and in function 2 - y=1/2x+3,  the slope, or rate of change, is also 1/2. This means that statement C. is correct. Hope this helps :) Good luck!!

Yuri [45]
Since she had $35.48 on her card.

Amount spent in buying coffee = $70 - $35.48 = $34.52

Cost of coffee = $8.63 per pound

No of pounds = Amount spent / cost per pound

= 34.52 / 8.63 Use your calculator.

= 4
