What is the answer and what are the steps to solving it?
Answers
7=−16t+16t+3
Step 1: Simplify both sides of the equation
.7=−16t+16t+3
Simplify: (Show steps)7=3
Step 2: Subtract 7 from both sides.
7−7=3−7
0=−4(no answer)

8-3<5 is already false so the answers are (0,0)and (-2,-3)

remember that the y axis runs up and down and the x axis runs left to right
on the y axis, up is positive and down is negative
on the x axis, right is positive and left is negative
they are written in (x,y) form
notice that there are not points to the left side of the origin (0,0) or the center so therefor there are no points/solutions where x is negative (remember that x is the left number)
so we can cross out (-1,0)
remember that if the second number (x,y) y=second number is equal to zero, then he point is on the x axis
(2,0) is in the part of the screen shown so that is the answer
answers are
1. (0,0) and (-2,-3)
2. (2,0)

Answer:
4. y+3=-1/3(x-9) 6a. 15x-y=0 6b. $150
Step-by-step explanation:
4.
Point slope form formula: y-y1=m(x-x1)
Includes origin and point (9,-3)
m= y2-y1/x2-x1
-3-0/9-0= -3/9=-1/3
slope= -1/3
Since we already have the point (9,-3),
enter the information above into the point slope form formula.
y-(-3)=-1/3(x-9)
y+3=-1/3(x-9)

3h--> $75
1h--> $15
a)
Standard form: Ax + By = C
m(slope)=15
y=15x
y-15x=0
-15x+y=0
15x-y=0
b)
