Answer:

Step-by-step explanation:

well i dont know what you are asking the measurment for but as you can see it is a circle which is automatically 360 degrees and than theres a line through the middle which is measurments F TO E which will make each side of the equation 180 automatically so for example;

CAE would be something that equals 180 hope this helps

<h3>Answer: Choice D) 56 degrees</h3>

How I got that answer:

Angle DCE is given to be 62 degrees. By the inscribed angle theorem, It doubles to 124 degrees, which is the measure of central angle DAE.

Note how angles DAF and DAE are a linear pair. This means they are adjacent supplementary angles. So they add to 180

(angle DAF)+(angle DAE) = 180

(angle DAF) + (124) = 180

angle DAF = 180-124

angle DAF = 56

(7x-y=7<br>(x+2y=6 estimate the solution to the system of equations

jolli1 [7]

Multiply the first equation by 2 to then use elimination by adding the 2 equations.

So, 14x-2y=14

+. x+2y=6

Equals 15x=20 so x=20/15=4/3

Plug in to first equation to get y

7(4/3)-y=7

28/3-y=7

28/3-y=21/3

So y=7/3

Plug both x and y into second equation to check

4/3+2(7/3)=

4/3+14/3=18/3=6 it works

So x=4/3, y=7/3

Hope this helps! Have a blessed day!

The graphs of f(x)=2x+4 and g(x)=10−4x intersect at (1,6) . What is the solution of the equation 2x+4=10−4x ? Enter your

nordsb [41]

X = 1, since they intersect at (1,6) and are thus equal at that point

If f(x)=4-11 what is the value of f(5)

Sveta_85 [38]

f(5) = 9

Do this by substitution:

f(x) = 4x - 11

f(5) = 4(5) - 11

f(5) = 20 - 11

f(5) = 9
