2x-4=x^2-4 
-4=x^2-2x-4 (start moving everything to one side)
x^2-2x=0 (the 4 cancel out)
x(x-2)=0 (factor out an x)
x=0 & x=2 (solved for x)

y=2x-4 (pick one of the equations)
y=2(0)-4 (plug in x)
y=-4
(0,-4)

y=2(2)-4 (plug in the second point)
y=0
(2,0)

The greatest possible value of s is 2. (2,0)

What is the answer to this question? <br> 1.4a^2+4a-63
LUCKY_DIMON [66]

Answer:

Step-by-step explanation:

Δ = 4^{2}  - 4 * 4 * (-63)  =  16 + 16 * 63 = 16 * (1 + 63) = 16 * 64

VΔ = 4 *  8 = 32

a = (- 4 ± 32) * \frac{1}{8}

a' = 7/2

a''= 9/2

Write an equation in point slope form of the line that passes through the given point and the given slope m
victus00 [196]

Answer:

The answer is

\huge y - 8 =  4(x + 9) \\

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

y -  y_1 = m(x -  x_1)

From the question we have the final answer as

y - 8 =   4(x + 9)

Hope this helps you

12) This one would be (b) because if you were reading it out loud it would be 2 is less than 3x, and 3x is greater than 5.

13) To make this easier for you I would change everything to a decimal.
Peaches: 3.25 pounds
Mangos: 4.35 pounds
Since the peaches are .89 per pound you times
3.25(.89)=2.8925 (which rounds to 2.89)
Since the magpies cost 1.26 per pound you would times
4.375(1.26)=5.5125 (rounds to 5.51)
Then 5.51-2.89=2.62
So the answer is A

14)3x is greater than or equal to nine
In this case x would have to be three or greater. So the answer would be B

15) The answer is B

16)c
— -5=20
2
You first get rid of your constant which in this case is -5, so you add 5 to both sides.
C
— -5=20
2
+5 +5
Then you would get
C
— =25
2
Now you want to try to get the variable alone, so you cancel the twos out, what you do to one side you have to do to the other.
2 C
— =25(2)
2
C=50
The answer is D
