THIS IS WORTH 50 POINTS WILL MARK BRAINLYEST PLEASE HELP

Since the first equation says y= x-4, substitution that for the y value in x + y = 6

x + x - 4 = 6

add up the x’s to get 2x - 4 = 6

add 4 to both sides to get 2x = 10

divide both sides by 2 to get x = 5

the x value is 5

then, to figure out the y value, substitute 5 for the x value in y = 5-4

the y value is 1

final answer: x = 5 and y = 1

hope this helped!!

In order to apply the law of sines to find the length of the side of a triangle, it is enough to know which of the following?

larisa86 [58]

Answer:

We must have two angles and a side.

A is the correct option.

Step-by-step explanation:

For any triangle ABC, the law of sine is given by

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

From this formula it is clear that in order to find the length of the side of the triangle, we must have two angles and a side.

Let us understand this by assuming that we need to find a (length of the side). From the formula, we have

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

Thus, to find the length a, we must have b, sin A and sin B.

Hence, o find the length of the side of the triangle, we must have two angles and a side.

I believe you just add all the numbers then divide by how many were there. You would divide by 16.

Through (-1,-1), slope of 4 what is the standard form equation of the line through the given point with a given slope

Vinvika [58]

Answer:

The equation of the line is -4x + y = 3

Step-by-step explanation:

Since we have the slope, we can use it and either point in point-slope form and solve for the standard form of the equation.

y - y1 = m(x - x1)

y - -1 = 4(x - -1)

y + 1 = 4(x + 1)

y + 1 = 4x + 4

-4x + y + 1 = 4

-4x + y = 3

Convert: a. 48 m^2 to ________________ cm^2

Lubov Fominskaja [6]

Step-by-step explanation:

1 m = 100 cm So

48 × 100 = 4800 cm

1m = 1000mm

456 mm into m

= 456 ÷ 1000

= 0.456 m
