What is the answer to this
stealth61 [152]
Hello!

The angle is a right angle, which measures 90°. 

3x + x = 4x

Angle = 4x + 10 = 90

Switch that around

90 - 10 = 4x

90 - 10 = 80

80 = 4x

Divide by 4

\frac{80}{4} =  \frac{4x}{4}]

\framebox{x = 20 \°}

PLEASE HELP 100 POINTS<br> write an equation of the horizontal line that passes through (-7,-10)
Vedmedyk [2.9K]

Answer:

y + 10 = 0

Step-by-step explanation:

Slope of horizontal line is zero (0)

m = 0

By point slope form of a line.

y-y_1 =m(x - x_1) \\  \\ y - ( - 10) = 0 \{x - ( - 7) \} \\  \\ y + 10 = 0 \{x + 7\} \\  \\y + 10 = 0 \\  \\

Which calculation should be used to calculate s9 for the arithmetic sequence an=3n-1
Ganezh [65]

Answer: Choice A

S9 = (9/2)*(2+26)

===============================================

The formula is

Sn = (n/2)*(a1+an)

where

Sn = sum of the first n terms (nth partial sum)

n = number of terms

a1 = first term

an = nth term

In this case,

n = 9

a1 = 2 (plug in n = 1 into the formula an = 3n-1 and simplify)

an = a9 = 26 (plug n = 9 into the formula an = 3n-1 and simplify)

So,

Sn = (n/2)*(a1+an)

S9 = (9/2)*(2+26)

will help us find the sum of the first 9 terms of this arithmetic sequence
