Answer:

x = 128 degrees

Step-by-step explanation:

So we know that a triangle's interior angles should add up to 180 degrees.

We also know that when a triangle has that little square in a corner, that corner is equal to 90 degrees.

With these clues, we can figure out that the last interior angle is equal to:

180 - (38+90) = 52, however this isn't the answer we are looking for.

We also know that a straight line is 180 degrees. Therefore, to find the exterior angle we just subtract the interior angle from 180 degrees:

180 - 52 = 128

x = 128

X = 120 minutes

(0.10)*(120) = 12

I'm pretty sure you just do 21 times 2. So your answer should be 42.

Answer: -7, 12

Step-by-step explanation:

a+b = 5

a*b = -84

a = 5-b

(5-b)*b = -84

-b^2 + 5b + 84 = 0

(-b - 7)(b + 12) = 0

The roots are -7 and 12.

Rounding 96.26 off to just 96  and then rounding 62.74 off to 62, you can subtract the two in your head real quick.

96 - 62 = 34

So using this estimation you can see that the answer of 159 is no where near correct.

Answer: y = -1/2x+15/2

Step-by-step explanation:

Hope this helps!

Answer:

y=3/2x+3/2

Step-by-step explanation:

point at (-6,-5)

slope = m = 3/2

y = mx+b

(-6)=(3/2)(-5)+b >>> substituting x & y to solve for b

-6 = (-15/2)+b >>> simplify previous equation

-6 + (15/2) = b >>> isolate and solve for m

3/2 = b

therefore, the equation of the line passing through the point (-6,-5) with a slope of 3/2 is y=(3/2)x+(3/2)

What is remainder R when the polynomial p(x) is divided by (2x - 1)? is (2x - 1) factor of p(x)?

p(x) = 2x² + 3x + 1

Answer :

R = 3

and (2x - 1) not factor of p(x) because, if (2x - 1) factor of p(x) remainder R when the polynomial p(x) divided by (2x - 1) is R = 0

∴ so the answer is option A
