Y = 3x + 3 this is equation 1
y = x -1 this is equation 2
since equation 1 and 2 already defined y in terms of x, we're just gonna substitute y into the other equation. as 2 is shorter I'm going with that today
x - 1 = 3x +3
-1 - 3 = 3x - x
-4 = 2x
x = -2
now we've got x just sub it in equation 2
y = -2 -1
y = -3
so the answer is (-2,-3)
Answer: 45
Explanation: two angles that form a Line always equal 180 degrees, so we start with the equation 180-u+47, which is the measure of the missing interior angle measure. All of the angles inside of a triangle also equal 180 degrees, so we can set up this equation to find U:
u-18+u+(180-u+47)=180
We can start to simplify by first simplifying what’s inside the parenthesis:
u-18+u+153-u=180
Then you solve the equation to get
U=45 degrees
Answer:
4(5 - 7x) = 6 - 12
20-28x=6-12x
Subtract 20 from both sides
20-28x-20=6-12x-20
Simplify
-28x=-12x-14
Add 12x to both sides
-28+12x=-12x=-12x-14+12x
Simplify
-16x=-14
Divide both sides by -16
-16/-16 = -14/-16

Answer:
Step-by-step explanation:
If the projectile is hitting something on the ground, it has a height of 0. Sub in a 0 for the h and factor to solve for t:
Factor out a -16t to get
0 = -16t(t - 2.5) which means that either t = 0 or t = 2.5
I'd say it has to be t = 2.5, don't you? ; )
