Answer:
B) $16.25
Step-by-step explanation:
$1.25 x 13=$16.25
Answer:
An infinite number.
Step-by-step explanation:
There are many, many rational fractions between -6 and -5.
For example, take the numbers - 5 2/7 and - 5 4/7. there is another rational between these - 5 3/7.
Then we have another between - 5 2/7 and - 5 3/7 which is - 5 5/14, - and we could go on doing this all day and never coming to an end!!
I'm not sure what you're asking here but if something's a parallelogram, all of the sides across from each other are parallel
Answer:
-1/4
Step-by-step explanation:
We can find the slope of the line given two points
m = (y2-y1)/(x2-x1)
= (-9- -6)/(3- -9)
= (-9+6)/(3+9)
=-3/12
= -1/4
Answer:
(- 4, - 12 ) , (4, 12 )
Step-by-step explanation:
Given the 2 equations
y = 3x → (1)
y = x² + 3x - 16 → (2)
Substitute y = x² + 3x - 16 into (1)
x² + 3x - 16 = 3x ( subtract 3x from both sides )
x² - 16 = 0 ( add 16 to both sides )
x² = 16 ( take the square root of both sides )
x = ± = ± 4
Substitute these values into (1) for corresponding values of y
x = - 4 : y = 3 × - 4 = - 12 ⇒ (- 4, - 12 )
x = 4 : y = 3 × 4 = 12 ⇒ (4, 12 )
