H(x) = 16 - x
plug -4 in as x
H(x) = 16 - (-4)
solve 16 - (-4)
H(x) = 20
your answer is A)20
Hi!
You can find the value of x by the fact that as triangle CBE and CKE are congruent. The reason you can see the triangles are congruent is because of the AAS congruence postulate, where if two angles are the same and a non included side are congruent, the triangles are similar. In this case, angle CKE and angle CBE, are congruent, and CEB and CEK are congruent as well. (They're marked out as congruent.) The line CE is congruent to the other CE in the other triangle, because they are the same line.
Since you know the triangles are congruent, according to CPCTC (corresponding parts in congruent triangles are congruent), and line CK is congruent to line CB, line CK is congruent to CB, and has the same measure.
Therefore, you can set the measures of CB (5x - 3) and CK (3x + 1) equal to another and solve for x.
5x - 3 = 3x + 1
5x -3 + 3 = 3x + 1 + 3
5x = 3x + 4
5x - 3x = 3x - 3x + 4
2x = 4
2x / 2 = 4/2
x = 2, or choice C.
Hope this helps!
Answer:
Number of ways to chose bracelet = 2 ways
Step-by-step explanation:
Given:
Total number of bracelet = 3
Y is chosen first
Find:
Number of ways to chose bracelet
Computation:
Y is chosen first so remain number of bracelet is 2
So,
Number of ways to chose bracelet = !2
Number of ways to chose bracelet = 2 × 1
Number of ways to chose bracelet = 2 ways
Answer:
Slope = 9
Step-by-step explanation:
(-7 , -2) ; x₁ = -7 and y₁ = -2
(-6 , 7) ; x₂ = -6 and y₂ = 7
Slope = 
![=\frac{7-[-2]}{-6-[-7]}\\\\=\frac{7+2}{-6+7}\\\\=\frac{9}{1}\\\\= 9](https://tex.z-dn.net/?f=%3D%5Cfrac%7B7-%5B-2%5D%7D%7B-6-%5B-7%5D%7D%5C%5C%5C%5C%3D%5Cfrac%7B7%2B2%7D%7B-6%2B7%7D%5C%5C%5C%5C%3D%5Cfrac%7B9%7D%7B1%7D%5C%5C%5C%5C%3D%209)
Starting point: (0, 2) and can go to (1, 6).
This shows the slope and y-intercept. Hope this helps.
