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

The answer is y= 23/4
Solve this equation. Enter your answer in the box.
75 – 3.5y – 4y = 4y + 6
y=6
Step-by-step explanation:
[tex]75 - 3.5y - 4y = 4y + 6[/tex]
Collect like terms and simplify
[tex] - 3.5y + 4y - 4y = 6 - 75 \\ - 11.5y = - 69[/tex]
Divide both sides of the equation by-3.5
[tex] \frac{ - 11.5y}{ -11.5} = \frac{ - 69}{ - 11.5} [/tex]
Simplify
[tex]y = 6[/tex]
The value of the y in the given equation is 6.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
For example, 3x – 5 = 16 is an equation.
Given that, an equation, 75 - 3.5y - 4y = 4y + 6, we need to find the value of y,
75 - 3.5y - 4y = 4y + 6
Combining the like terms,
75 - 6 = 4y + 4y + 3.5y
69 = 11.5y
y = 6
Hence, the value of the y in the given equation is 6.

The gas tank in Daniel's car has a capacity of 19.1 gallons.
On a trip to see his best friend Daniel begins with 12.8 gallons of gas in the tank.
He stops after driving for 2 hours and fills the tank to capacity with 14.4 gallons.
When Daniel arrives at his friend's house, he has 3.7 gallons of gas left.
Total amount of gas filled was (12.8 + 14.4) = 27.2 gallons.
The amount of gas remaining after the trip was 3.7 gallons
The amount of gas, in gallons, used by Daniel on his trip was 27.2 - 3.7 = 23.5 gallons

Step-by-step explanation:
Hannah works at an electronics store as a salesperson. Hannah earns a 7% commission on the total dollar amount of all phone sales she makes, and earns a 7% commission on all computer sales.
How much money would Hannah earn in
commission on a day that she sold $1000 worth of phones and $1700 worth of computers?
How much money would Hannah earn in commission on a day that she
sold $p worth of phones and $c worth of computers?
Answer:
Step-by-step explanation:1000x.07 70
1700x.07. 119
119+70. 189
The amount of commission earned on a day that she sold $1000 worth of phones and $1700 worth of computers is $189.
The amount Hannah earns in commission on a day that she
sold $p worth of phones and $c worth of computers is 0.07 ( p + c).
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Commission on phones = 7%
Commission on computers = 7%
Now,
Sold phones worth = $1000
Computer sold worth = $1700
Now,
The total commission earned.
= 7/100 x 1000 + 7/100 x 1700
= 70 + 119
= $189
Now,
The total commission earned.
= 7/100 x p + 7/100 x c
= 7/100(p + c)
= 0.07 (p + c)
Thus,
$189 commission was earned.
0.07 ( p + c) commission was earned.

Determine if the two lines y = 2x - 3/2 and y = -2x + 2/3 are parallel, perpendicular or neither. Explain
Answer:
Neither
Step-by-step explanation:
For two lines to be parallel, they must have the same slope. 2 and -2 are not the same. For lines to be perpendicular, their slopes must be negative reciprocals (ex 5 and -1/5) The slopes of these lines are not the same or negative reciprocals, so they are not parallel or perpendicular.

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
