Answer:
B. (1,5) and (5.25, 3.94)
Step-by-step explanation:
The answer is where the 2 equations intersect.
We need to solve the following system of equations:
y = -x^2 + 6x
4y = 21 - x
From the second equation:
x = 21 - 4y
Plug this into the first equation:
y = -(21 - 4y)^2 + 6(21 - 4y)
y = -(441 - 168y + 16y^2)+ 126 - 24y
y = -441 + 168y - 16y^2 + 126 - 24y
16y^2 + y - 168y + 24y + 441 - 126 = 0
16y^2 - 143y + 315 = 0
y = [-(-143) +/- sqrt ((-143)^2 - 4 * 16 * 315)]/ (2*16)
y = 5, 3.938
When y = 5:
x = 21 - 4(5) = 1
When y = 3.938
x = 21 - 4(3.938) = 5.25.
Answer:
The answer is A
Step-by-step explanation:
Answer:
It’s y2-y1 over x2-x1
Y2 is 5 and y1 is 5
5-5
X2 is 7 and x1 is -2
7- negative 2
5-5 is 0
7- negative 2 is 9
Slope is 0

The answer is 2.5 because you need to divide it and then you get your answer
Answer:
The value of x for the given expression is (95/27)
Step-by-step explanation:
Here, the given expression is:

Now here solving for the value of x , we get

Now, taking the variable terms on 1 side, we get

or, 
Hence, the value of x = (95/27)
