Angle A and angle B are complementary angles. If m angle A = (x + 8) and m

1 answer:

7 0

Answer:

17

Explanation:

(x + 8) + (8x + 1) = 90

Combine like terms to get:

9x + 9 = 90

Subtract 9 on both sides:

9x = 81

Divide by 9:

x = 9

Plug in 9 for x in
9 + 8 = ?

9 + 8 = 17

Please help I'm really stuck

Anit [1.1K]

First factor the numerator
b^2-6b+8/b-4 * b+8/b-2

u will get
(b-2)(b-4)/(b-4)*(b-2)*b+8
those will cancel out each other will left only
b+8<span />

How do I find angle a?

vfiekz [6]

The slope of the line is 2/3, so the angle is arctan(2/3) ≈ 33.69°.

A truck can travel 80 miles in the same time that ot takes a car to travel 90 miles. If the truck’s rate is 5 miles per hour slo

SIZIF [17.4K]

The truck was going 40 miles per hour

The amount of time was 2 hours:
(90-80: 10)(10/2=5)

80 divided by two is 40

The car was going 45 miles per hour

(90-80:10)(10/2=5)

90 divided by two is 45

Hey, Its the same person. This is Algebra 2. Please Help!

Answer:

first option

Step-by-step explanation:

Given

f(x) = $\frac{2x^2+5x-12}{x+4}$ ← factorise the numerator

= $\frac{(x + 4)(2x-3)}{x+4}$ ← cancel (x + 4) on numerator/ denominator

= 2x - 3

Cancelling (x + 4) creates a discontinuity ( a hole ) at x + 4 = 0, that is

x = - 4

Substitute x = - 4 into the simplified f(x) for y- coordinate

f(- 4) = 2(- 4) - 3 = - 8 - 3 = - 11

The discontinuity occurs at (- 4, - 11 )

To obtain the zero let f(x) = 0, that is

2x - 3 = 0 ⇒ 2x = 3 ⇒ x = $\frac{3}{2}$

There is a zero at ( $\frac{3}{2}$ , 0 )

Thus

discontinuity at (- 4, - 11 ), zero at ( $\frac{3}{2}$ , 0 )
