Answer is A
if x+y=5
y= -x+5
2x + (-x+5) =-2
2x -x +5 = -2
x+5 = -2
x=-7
Answer:
12.5%
Step-by-step explanation:
% increase = (new value - initial value)/initial value x 100
= (90-80)/80 x 100
=10/80 x 100
= 12.5%
Answer: Square
Step-by-step explanation:
A cross section cut parallel to a base will be the same shape as the base itself, and the base of a cube is a square. :)
Yes, the graph is a function and it does pass the vertical line test because when you hold a ruler up to it, you can see that the graph only hits one point at a time.(im not so sure about this, im sorry :/ )
Yes, your range is 2, since that is your y-intercept.
And your other answer choices are incorrect.
<span>The goal in simplifying numbers
is to reduce it that can be best seen in the eye. In here, you are given 5a²x(-3b²)x2c. Note that 5, -3 and 2 are
coefficients and a², b² and c are variables. Multiply first the coefficients 5, -3
and 2 and you get -30. Always remember that in multiplying numbers, especially
variables, the base of the exponent must be equal. However, you have variables
of a²,
b²
and, c. You cannot multiply or add them because they are different. So the
answer is -30a² b²c.</span>
