Answer:
The answer is D. Vertex at (-7,-9).
Step-by-step explanation:
The equation is in vertex form, so you take the opposite of x and the constant stays the same. So, the opposite of 7 is -7 and -9 stays the same.
1. Which equation represents a line that passes through the point (-2,6) and is parallel to the line whose equation is 8x – 4y = 6?
Answer:
y=2x+10
Step-by-step explanation:
First, let's put the equation into slope-intercept form. We get y=2x-3/2.
Parallel lines have the same slope, so the slope of the line will be 2.
We then substitute the point into the equation to find the y-intercept.
We get y=2x+10

Ms. W has 400 followers on Twitter and is gaining 75 followers each day. Mrs. Hill has 1,000 followers on Twitter, but is losing 25 followers a day. How many days will it take them to have the same number of followers?
Answer:
It takes 6 days.
Step-by-step explanation:
First, you have to form expressions for both of them in terms of x. Let x be the number of days :
Ms. W = 400 + 75x
Mrs. Hill = 1000 - 25x
Next, you have to compare it as we want to find out how many days in takes for them to have the same number of followers :
400 + 75x = 1000 - 25x
75x + 25x = 1000 - 400
100x = 600
x = 6

Devaughn is 13 years younger than Sydney. The sum of their ages is 79 . What is Sydney's age?
Answer: 46 years old
Step-by-step explanation: If Devaughn is 13 years younger than Sydney,
we can represent Sydney's age as x and Devaughn's age as x - 13.
Since the sum of their ages is 79, we have x + x - 13 = 79.
This simplifies to 2x = 92.
Dividing both sides by 2, we have x = 46.
So sydney is 46 years old.

Answer:
x=60
Step-by-step explanation:
Answer: The equation 60 + x= 3x -70 could be set up to solve for x.
Step-by-step explanation:
The two remote interior angles sums will equal to the exterior angle .
Meaning that angle 60 plus angle x has to equal to angle 3x -70.
60 + x= 3x -70 Now solve for x by adding 70 to both sides
+70 +70
130 + x = 3x Now subtract x from both sides
-x -x
130 = 2x Divide both sides by
x = 65
what's y intercept on a graph of y = -5x + 6
The y-intercept on a graph of y = -5x + 6 is 6.
What are intercepts?The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively.
We have a linear equation,
y = -5x + 6.
The general slope-intercept form,
y = mx + b.
Where m is the slope and b is the y-intercept.
Comparing,
b = 6.
Therefore, 6 is the y-intercept.
