Answer:

C) {12, 4, −6}

Step-by-step explanation:

$\displaystyle 4 - 2[5] = 4 - 10 = -6 \\ \\ 4 - 2[0] = 4 ∓ 0 = 4 \\ \\ 4 - 2[-4] = 4 + 8 = 12$

I am joyous to assist you anytime.

12(5+2y)=4y-(6-9y) How to Solve

kvv77 [185]

Answer:

y = -6

Step-by-step explanation:

12 (5 + 2y) = 4y- (6 - 9y)

= 60 + 24y = 4y - 6 + 9y

= 60 + 24y = 13y - 6

= 24y - 13y = -6 - 60

= 11y = -66

y = -6

In triangle XYZ, angle Y = 45º and angle Z = 60º. If XZ = 4, then what is XY?

Katena32 [7]

Answer:

$XY = 4.9$

Step-by-step explanation:

Given

$XZ= 4$

$\angle Y = 45$

$\angle Z = 60$

Required

Determine the measure of side XY

To do this, we make use of sine law. This is as follows:

$\frac{a}{\sin\ A} = \frac{b}{\sin\ B} = \frac{c}{\sin\ C}$

In this case:

$\frac{4}{\sin(45)} = \frac{XY}{\sin(60)}$

Cross Multiply

$XY * \sin(45) = 4 * \sin(60)$

$XY * 0.7071 = 4 * 0.8660$

Make XY the subject

$XY = \frac{4 * 0.8660}{0.7071}$

$XY = \frac{3.4640}{0.7071}$

$XY = 4.89888276057$

$XY = 4.9$ -- <em>approximated</em>
