Answer:

Step-by-step explanation:

1 is linear with 138, and they must add to 180, so 180 - 138 = 42

It’s A. 42° Because together, the 138° angle and angle two need to equal 180°. So do 180-138=42

The difference between two number is 9 and the product of the number is 162 find the 2 number

erik [133]

Answer:

18 and 9

-18 and -9

Step-by-step explanation:

Let:

first number = x

second number = y

According to given conditions:

x - y = 9 ---------- eq1

x * y = 162 ------- eq2

From eq1:

x = 9 + y

Put it in eq2:

(9+ y)*y = 162

9y + y^2 - 162 = 0

y^2 + 9y -162 = 0

By factorizing we get:

y^2 -9y + 18y - 162 = 0

Taking common:

y(y - 9) + 18(y - 9) = 0

(y - 9)(y + 18) = 0

So:

y = -18 and y = 9

ignoring negative integer

Putting values of y in eq1:

x - 9 = 9

x = 9 + 9

x = 18

So the two numbers are:

18 and 9

-18 and -9

i hope it will help you!

M (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. Switch the x- and y-coordinates: (6, –3) 2. Multiply the new x-co

GalinKa [24]

Answer:

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation is rotation, reflection, translation and dilation.

If a point (x, y) is rotated 90° counterclockwise, its new coordinate is (–y, x).

Give point M (3, –6) is rotated 90° counterclockwise:

Step 1: Interchange the x- and y-coordinates to get (-6, 3)

Step 2: Multiply the new x-coordinate by –1 to get (-6(–1), 3)

Step 3: Simplify to get (6, 3)

Therefore she made an error in step 1

3/4a−16=2/3a+14 PLEASE I NEED THIS QUICK and if you explain the steps that would be geat:) Thank youuuuuuu

Jlenok [28]

Answer:

360

Step-by-step explanation:

3/4a - 16 = 2/3a + 14 ⇒ collect like terms
3/4a - 2/3a = 14 + 16 ⇒ bring the fractions to same denominator
9/12a - 8/12a = 30 ⇒ simplify fraction
1/12a = 30 ⇒ multiply both sides by 12
a = 30*12
a = 360 ⇒ answer
