Determine the x- and y- intercepts for the graph defined by the given equation.
x = -9

Answers

Answer 1

Answer:

Answer:

a. x - intercept = (-9, 0)

No, y-intercept

Step-by-step explanation:

Since equation of line is x = - 9,

If we draw a graph of it, we will find that line will go parallel to y-axis intersecting x-axis at (- 9, 0).

Hence,

x - intercept = (-9, 0)

No, y-intercept

is the correct answer.

Answer 2

Answer:

Step-by-step explanation:

No y-intercept

X-intercept is (-9,0)

A) 3

Step-by-step explanation:

We know that the diagonals of the parallelogram intersect in half.

Therefore we hawe the equation:

x - 30 = -9 - 6x add 30 to both sides

x = 21 - 6x add 6x to both sides

7x = 21 divide both sides by 7

x = 3

X=3 hope this helps sorry if I’m wrong

katie has read 34% of her book. if she has read 85 pages, does she have more than or fewer than 125 pages left to read?

Answers

Okay so first I just go to the wording of the first part, reading it again as something like "85 is 34% of what number?" Then I translate it by putting an = for the "is", an x (times) for the "of", and a variable, w for "what number". Because it's a percent, we get rid of the % sign by writing 34/100, or .34 . Then we just have:
85=.34 x a
Divide off the .34
a=250
Now for the second part. 250 is the total number of pages, so subtract 85 to get the number of pages she hasn't read.
250-85=165
So she has more than 125 pages left.

Consider this composite figure.
