Answer:
The first
The third
The fifth
Step-by-step explanation:
To be able to count the units, either the x coordinates need to be the same
or the y coordinates need to the the same
The first has the same y coordinates
The third has the same y coordinates
The fifth has the same y coordinates
The others required the distance formula since both x and y change
Answer:
C.) y = 3(x - 3)(x - 7)
For the function:
- x intercept: (3, 0), (7, 0)
Writing equation:
y = a(x - h)² + k
15 = a(8 - 5)² - 12
15 = 9a - 12
9a = 15 + 12
9a = 27
a = 3
So the equation is:
y = 3(x - 5)² - 12
y = 3(x² - 10x + 25) - 12
y = 3x² - 30x + 63
y = 3(x - 3)(x - 7)
Answer:
Step-by-step explanation:
<u>Let the length be x:</u>
A = lw ⇒ formula for the area of rectangle
A = 255 cm²
- x(x+2) = 255
- x^2 + 2x + 1 = 256
- (x+1)^2 = 16^2
- x + 1 = 16
- x = 15
l = 15 cm, w = 17 cm
10-8= 2. 6+4=4. the answer is B
