The answer is the first one . A
Answer:
<u>True:</u>
The solution is the product of two factors.
The second factor is itself the sum of three terms.
<u>False:</u>
The solution is the sum of two terms.
The coefficient is 3. (This one I'm confused about. There is no x/letter term, so there shouldn't be a coefficient in this problem at all.)
The second factor is the sum of two terms.
Answer:
P’ = (4, 5)
Q’ = (5, 3)
R’ = (1, 1)
Step-by-step explanation:
Answer:
(4,4)
Step-by-step explanation:
y = 2x - 4 -------eqn 1
4y = x + 12 ------eqn 2
From eqn 1 y = 2x - 4; insert in eqn 2
4 (2x-4) = x + 12 (open the bracket)
8x - 16 = x + 12 (taking like figures to the same side, sign changes)
8x - x = 12 + 16
7x = 28
x = 28/7
x = 4
From eqn 1
y = 2x - 4
y = 2(4) - 4
y = 8 - 4
y = 4
(x,y) = (4,4)
Step-by-step:
1. Identify the coefficients a and b (a=1/2, b=2)
2. Then put those numbers in the vertex formula which is x= -b/2a (-2/2*1/2)
3. Solve for x (x= -2)
4. Find the y-coordinate of the vertex by plugging in x= -2 (y= 1/2(-2)^2+2(-2)- 3)
5. Calculate all of that (y= -5)
6. Put those to coordinates together (Remember: x= -2, y= -5)
7. So your vertex would be (-2, -5)
I hope that made sense ☺️!
