Answer:
This is linear equation you're asked to find C I guess so collect like terms and find X
x=-6-14
x=-20
Answer: Ok so I'm not sure what your question is but if you are looking for y then the answer is y= 3 - x, if you are looking for x then the answer is x = 3 - y.
4)
Non linear:
y = 6 -x^2
y = 2x^2 + 2
y = x^3
5)
Rate of change is also the slope
= (72 - 69) / (51 - 48)
= 3/3
= 1
Rate of change = 1
6)
First you need to find slope
(3,0) and (5,2)
Slope = (2 - 0)/(5-3) =2/2 = 1
Equation
y - 0 = 1(x - 3)
y = x - 3
Answer:
Tyler's function is correct as y = x - 3, it matched the above.
The answer is C.) 62.
Subtract 28 from 180, leaving 152, then subtract 90 since it's a right triangle because 2 sides are equivalent, leaving 62.
Answer:
Speed of car B is 33 km/h and speed of car A is ![45\,\,km/h](https://tex.z-dn.net/?f=45%5C%2C%5C%2Ckm%2Fh)
Step-by-step explanation:
Let speed of car B be
km/h
Speed of car A is 12 km/h more than car B.
Therefore,
Speed of car A =
km/h
Distance = Speed × Time
Distance travelled by car A in 4 hours =
km =
km
Distance travelled by car B in 4 hours =
km
Also, cars A and B are 312km apart after 4 hours.
![48+4x+4x=312\\48+8x=312\\8x=264\\\\x=\frac{264}{8}\\\\x=33\,\,km/h](https://tex.z-dn.net/?f=48%2B4x%2B4x%3D312%5C%5C48%2B8x%3D312%5C%5C8x%3D264%5C%5C%5C%5Cx%3D%5Cfrac%7B264%7D%7B8%7D%5C%5C%5C%5Cx%3D33%5C%2C%5C%2Ckm%2Fh)
Speed of car B is 33 km/h and speed of car A is ![12+x=12+33=45\,\,km/h](https://tex.z-dn.net/?f=12%2Bx%3D12%2B33%3D45%5C%2C%5C%2Ckm%2Fh)
