Answer:
C
Step-by-step explanation:
The range is the values of y from the vertex upwards
The vertex = (- 2, - 4) → y = - 4
The range is from - 4 upwards in the direction of the parabola, that is
range is [ - 4, ∞ )
7 7/8= 63/8
3 1/4= 13/4
63/8 -13/4 we bring to the same denominator
(63-26)/8= 37/8
Answer:
0
Step-by-step explanation:
The five smallest prime numbers are 2, 3, 5, 7 and 11.
2 × 3 × 5 × 7 × 11
= 2310
Divide by 42.
2310/42
= 55, Remainder 0
Answer:
the length of the table is 108 inches
Answer:
x = 42
Step-by-step explanation:
The marked angles are supplementary, so their sum is 180°.
(2x +8) +(2x +4) = 180
4x +12 = 180 . . . . . . . . . simplify
x +3 = 45 . . . . . . . divide by 4 (because we can)
x = 42 . . . . . . subtract 3

<em>Additional comment</em>
A "two-step" linear equation like this one is usually solved by subtracting the unwanted constant, then dividing by the coefficient of the variable. Here, we have done those steps in reverse order. This makes the numbers smaller and eliminates the coefficient of the variable. Sometimes I find it easier to solve the equation this way.
