Answer:
B and C
Step-by-step explanation:
(-7)•8z = -56z
(-4)•(-7)=28
and
40•(-1.4)= -56z
40•0.7= 28
I am not certain of what you wrote for the function but will assume that is likely exponential function or quadratic function.
First, (quadratic function) To solve this, you must know the quadratic formula. The x-intercept is value(s) that has the output value(y) of 0.
If the vertex of the quadratic function of (0,0), there is only one x-intercept. The number and value of the x-intercept depends on the slope and vertical displacement.
Second, (exponential function) note that there is no x-intercept. For instance, if a is 2, is there such value y that 2^y is 0? The smallest exponential value that is an integer is 1. Even broadening the limit to rational numbers, no such exponential value can have the result of 0. Therefore, in the basic form of exponential function, there is no x-intercept.
Answer:
The Arch is 630 ft tall
Step-by-step explanation:
The answer is A.
If a redundant conclusion is reached in basic algebra this states that the variable holds all possible real values.
If you algebraically solve Kendra's you do achieve the true statement 5 = 5 (leaving out D). And if you test any value of x for the equation it does hold true (getting rid of B).
Hopefully this makes sense.
Answer:
D. x = 8
Step-by-step explanation:
MNOP is a trapezoid with a meadian QR
So
QR = 1/2(NO + MP)
2(QR) = NO + MP
2(16) = 8 + 2x + 8
32 = 2x + 16
2x = 16
x = 8
