Answer:

-7

Step-by-step explanation:

  • -a - 2 = -5 + -2 (different sign- keep the first number same, change the sign to         addition and the additive inverse of the second number)
  • -5 + -2 = -7

Hope this helps

A(1)=20
Paladinen [302]

Answer:

-14

Step-by-step explanation:

You've got a(1)=20

a(1) means a(n) when n=1

the sequence is telling you to take the previous value of a(n), which is a(n-1) and subtract 17

then:

a(2) = a(1)-17 = 20 - 17 = 3

a(3) = a(2) - 17 = 3-17 = -14

A line passes through the point (1, - 6) and has a slope of 8. Write an equation in slope-intercept form for this line.
Annette [7]

Answer:

\boxed {\boxed {\sf y=8x-14}}

Step-by-step explanation:

We are asked to find the equation of a line in slope-intercept form. We are given a point and a slope, so we can use the point-slope formula.

y-y_1= m(x-x_1)

In this formula, m is the slope and (x₁, y₁) is the point the line passes through. The slope of the line is 8 and it passes through the point (1, -6). Therefore,

  • m= 8
  • x₁= 1
  • y₁= -6

Substitute these values into the formula.

y- (-6) = 8(x-1)

Remember that 2 back to back subtraction signs are the same as an addition sign.

y+6=8(x-1)

The line must be in slope-intercept form or y=mx+b (m is the slope and b is the y-intercept. We must isolate the variable y on one side of the equation. First, distribute on the right side of the equation. Multiply each term inside the parentheses by 8.

y+6 = (8*x) + (8*-1)

y+6= (8x)+ (-8)

y+6=8x-8

6 is being added to y. The inverse operation of addition is subtraction, so we subtract 6 from both sides of the equation.

y+6-6=8x-8-6

y=8x-8-6

y= 8x-14

The equation of the line in slope-intercept form is <u>y=8x-14</u>. The slope is 8 and the y-intercept is -14.
