Answer:
(a) y=8x-46
(b) 8x-y=46
Step-by-step explanation:
-y=-8x+4
y=8x+4
We know that 8 is the slope, and if we need a equation parallel to this line, then it will have the same slope.
Substitute (6,2)
2=8(6)+b
2=48+b
b=-46
The final answer is y=8x-46
Answer:
r<=-8 or r is less than or equal 8
Step-by-step explanation:
-2r+3>=19
-2r>=16
r<=-8
you flip the sign when the variable is a negative. To plot this on a number line place a close circle on -8 moving to the left direction.
I believe it’s B since both A and B are the same angle so the rest wouldn’t make sense
Answer:
The ball will be the 7 ft high at 2 different times.
Step-by-step explanation:
The height in meters of the ball is given by the following equation:

7 feet high
The height, by the equation, is given in meters, so we have to work in meters. Since each feet has 0,3048 meters, 7 feet have have 2.1336 meters. So, we have to solve the following equation


At how many different times will the ball be 7 ft. High?
We have to find the number of solutions for the equation above.
It is given according to the value of
. If it is positive, there are two solutions, zero one solution and negative no solutions.
In this equation
. So

Since the coefficient is positive, the ball will be the 7 ft high at 2 different times.
Step-by-step explanation:
Given
Slope (m) = 2/3
y - intercept ( c ) = 5
Now
Writing in slope intercept form
y = mx + c
y = 2/3 x + 5
Hope it will help :)❤
