Answer:
3: x = 3 4: y = 8
Step-by-step explanation:
Problem 3:
Because of the lines on each side of the rhombus, that shows you that all of those lines are congruent with each other, meaning they are all the same length. So since one side equals the other, you can equal one of the equations on one side to another equation on another side. EX: x+5 = 3x-1. And then you solve that through multi-step equations.
Problem 4:
Just like on Problem 3, due to the little dashes going through the sides of the rectangle, the sides are congruent (the same length) as one another. Except the sides with one dash are not congruent with the sides with two dashes. But if you equal 2y and y+8, then you can solve that through multi-step equations again and get y = 8 since they are congruent with each other (due to the singular dashes running through their sides).
Hope this helped!
Equation for line: y=mx+b where m is the slope and b is the y-intercept
We have the slope. We just need to find the y-intercept. Plug in the point and the slope and solve for b.
y=mx+b
1=4(-5)+b
b=21
Answer: y=4x+21
Simplify the equation as best you can and then graph it. When you have graphed it, the x-coordinate when y=0 is x.
Given the following question:
Lable all the sides of the triangle:
Hypotenuse is the missing side
Right angle is the opposite
Adjacent is equal to 21
We have all of our sides so now we won't get them mixed up when finding the missing value of this triangle.
sin =
opp/hyp
cos =
adj/hyp
tan =
opp/adj
Since we are given the adjacent side and we are trying to find the hypotenuse we will solve for cos since we have the adjacent side but we need the hypotenuse
cos(35)=21/x
Now solve:

I don't get the question well,so if u can reframe it
