PLEASE HELP ME ASAP!!!!! I ONLY HAVE 2 ATTEMPTS LEFT!!!!

Mathematics
1 answer:
Simora [160]3 years ago
5 0

Answer:

m∠1 = 105°

m∠2 = 75°

Step-by-step explanation:

Lines a and b are parallel.

1. Angles 1 and 75° are the same side angles when two parallel lines a and b are cut by transversal t.

The same side angles add up to 180°, so

m∠1 + 75° = 180°

m∠1 = 180° - 75°

m∠1 = 105

2. Angles 2 and 1 are supplementary (add up to 180°), then

m∠1 + m∠2 = 180°

m∠2 = 180° - 105°

m∠2 = 75°

Multiply<br> (x-6)(4x + 3)<br> A. 47-32-18<br> B. 4) - 24%-18<br> C. 47 - 21%-18<br> D. 4/2 - 18
PilotLPTM [1.2K]

Answer:

4x² - 21x - 18

Step-by-step explanation:

Use FOIL.

(x-6)(4x+3)\\\\x*4x = 4x^2\\\\x * 3 = 3x\\\\-6 * 4x= -24x\\\\-6 * 3 = -18\\\\\\4x^2+3x-24x-18\\\\\boxed{4x^2-21x-18}

Hope this helps.

What are the coordinates of P' if P (-5,-4) undergoes a dilation, centered at the origin, with a scale factor of K=2?
Margaret [11]

Answer:

P' = (-10,-8)

Step-by-step explanation:

Given

P = (-5,-4)

k =2

Required

Determine the image P'

P' is calculated by multiplying P and k.

i.e.

P' = P * k

This gives:

P' = (-5,-4) * 2

P' = (-5* 2,-4* 2)

P' = (-10,-8)

<em>Hence, the image P' after dilating P is (-10,-8)</em>
