Answer:
Step-by-step explanation:
1) First, distribute the 10 and the -8 to the terms in the parentheses next to them. Remember, don't distribute to the -4h since it is not in the parentheses.
2) Next, combine like terms. (Any terms that have the same variables must be added together by their coefficients.)
There are no more like terms to combine, so is the answer.
Answer:
(6,26)
Step-by-step explanation:
You will take the points and graph them since these are both positive equations they will go up and to the right.
both intersect at (6,26)
also if you forgot how to graph it, I got you
1. find the rate of change (as I will call it) THIS IS YOUR NUMBER NEXT TO THE X!!! this means that the line will go up 4 and over 1 then your whole number, in this example would be 2 is your y-intersect (the place on the y-axis where the line passes) after that you should be able to draw your lines and find the poi!
Please comment if I got something wrong! I don't want to be giving bad advice
The answer is B x = -4. x= 3
You must factor the equation by find what 2 numbers can multiply to equal -12 and add to equal 1.
-3 and 4 are the two numbers. Now to put it in factor form would be:
(x - 3)(x + 4) = 0
They y also must equal zero.
Since its equals to 0, we must solve for x for the binomial.
x - 3 = 0 ; x = 3
x + 4 = 0 ; x = -4
The answer you get from solving x, is that answer
You'll have to be more specific, like what is each side, as in height, width or length. Sorry!
step 1
Find out the slope WX
W(2,-3) and X(-4,9)
m=(9+3)/(-4-2)
m=12/-6
m=-2
step 2
Find out the slope YZ
Y(5,y) and Z(-1,1)
m=(1-y)/(-1-5)
m=(1-y)/-6
m=(y-1)/6
step 3
Remember that
If two lines are perpendicular
then
their slopes are negative reciprocal
that means
(y-1)/6=1/2 -----> because the negative reciprocal of -2 is 1/2
solve for y
2y-2=6
2y=6+2
2y=8
<h2>y=4</h2>
