Answer:

  (x, y) = (0, -26)

Step-by-step explanation:

The y-intercept is the y-value that corresponds to x=0. Here, we have a table that has x-values that differ by 12 and 24. We want to find the y-value that corresponds to an x-value 24 less than the lowest one on the table:

  24 -24 = 0

We notice that when x-values differ by 24, the y-values differ by 10 -(-8) = 18. So, the y-value we want is 18 less than the lowest one in the table:

  y = -8 -18 = -26

The (x, y) coordinates of the y-intercept are (0, -26).

Which term of series1 +4+7+10+...is43
Jlenok [28]

Answer:

a = 4

d = a2 - a1

d = 7 - 4

d = 3

an = 43

an = a + (n - 1)d

43 = 4 + (n - 1) 3

43 = 4 + 3n - 3

43 = 1 + 3n

43 - 1 = 3n

3n = 42

n = 42 ÷

n = 14

So, 14th term is 43

Given the figure below, find the values of x and z.<br> (5x + 86)<br> (10x + 34)<br> X =<br> Z=
kolezko [41]

Answer:

x = 4 \\ z = 106

Step-by-step explanation:

(5x + 86) + (10x + 34) = 180 \\ 15x + 120 = 180 \\ 15x = 180 - 120 \\ 15x = 60 \\  \\ x =  \frac{60}{15}  \\  \\ x = 4

(5x + 86) = 5(4) + 86 = 20 - 86 = 106

Z= 106 —> Opposite angles
