The answer is x=4because 4x-2 is 2x and 10x-12 is 2x and 2x plus 2x is 4x so x=4

Which congruence theorems or postulates could be given as reasons why ABC =XYZ HELP !!!!

Answers:
A) SAS
B) ASA
E) LL

============================================================

Explanation:

Let's go through each possible answer choice

A. We can use SAS because we know that AC = XZ (horizontal sides) is one pair of congruent sides, the angle pairing is C = Z, and the other pair of sides is BC = YZ (vertical sides)

B. We can also use ASA. Note how A = X is one pair of angles, AC = XZ is the middle pair of sides, and C = Z is the second pair of angles. The side is between the angles.

C. We can't use SSS as we don't know AB = XY is true or not. There are no tick marks indicating congruence.

D. We can't use LA here because we don't know the altitudes (LA = leg altitude)

E. We can use LL here because we have two right triangles. The two pairs of legs (AC = XZ and BC = YZ) are congruent based on the tickmarks.

F. We can't use HL similar to the reasoning for choice C. We don't know the hypotenuses are congruent or not. If we knew that AB = XY, then we could use HL (hypotenuse leg).

Stephen found the line of best fit to be p=-23+0.13y predict the average points per game to the nearest tenth for values of 350,

NISA [10]

P = -23 + 0.13y

For y = 350:
p = -23 + 0.13(350) = -23 + 45.5 = 22.5

For y = 400:
p = -23 + 0.13(400) = -23 + 52 = 29

For y = 450:
p = -23 + 0.13(450) = -23 + 58.5 = 35.5

Can someone please answer these questions?

Keep in mind that you can gather only like terms. Two terms can be summed/subtracted if they involve the same powers of the same variables.

So, going point by point:

We can subtract the terms, because they both involve the variable $b$ , and we have $3b-7b = (3-7)b = -4b$
We can sum the terms, because they all involve the variable $a$ , and we have $a+a-5a = (1+1-5)a = -3a$
We can't sum this terms: 3 is a pure number, while 3r involves the variable r.
We can only sum the two terms: we have $7t-8t-8 = (7-8)t-8 = -t-8$
We can't sum this terms: -20 is a pure number, while -15p involves the variable p.
We can sum the terms, because they all involve the variable $g$ , and we have $-g-g-g = (-1-1-1)g = -3g$
