Y = -1/2x + 4
2y = -x + 8
x + 2y = 8: the standard form
She earned 10 donations.
2.50 ÷ .25 = 10
To double check you can go 10 × .25 = 2.5 then you just add the zero at the end and it becomes 2.50
Answer:
8y= -16
7x= -7
so 1y =-2 meaning 8y is -16 + 7x and if 1x is -1 then it is -7 altogether so if you add -16 and -7 you get -23
The measure of angle QPS in circle C is 112°
<h3>What is a
circle?</h3>
A circle is the locus of a point such that its distance from a fixed point known as the circle center is always constant. The sum of angles in a circle is 360 degrees.
From the circle:
PQ is parallel to SR, hence: ∠PQR + ∠QRS = 180°
∠PQR + 68 = 180
∠PQR = 112°
Also, PS = QR (from the endpoint of the diameter), hence:
∠QPS = ∠PQR = 112°
The measure of angle QPS in circle C is 112°

Answer:
-136
Step-by-step explanation:
This series can be written as: (14 - 3*0) + (14 - 3*1) +...+ (14 - 3*n)
The sum of the first 16 terms is:
14*16 <u>- 0 - 3 - 6 - 9 -...</u> = 224 - 360 = -136
This underlined bit can be calculated in many ways, I personally used my calculator, but there are formulas to do so.
