Answer:
y=3x-21
Step-by-step explanation:
a line is parallel if the slopes of the lines are the same
so that means that out line should look something like this
y=3x+b
then, we use our point given to find b
-3=18+b
b=-21
the equation of out line is y=3x-21
In order to get the total price, we can multiply the 4 dollars by .05 to find 5 percent of the object's cost and add it to the sales tax. So, .05 times 4 is 0.2, meaning there is a sales tax of 0.2 dollars. We add that to the four, so the total price is 4.20 dollars. Hope this helps.
Answer:
Step-by-step explanation:
They have different y intercepts.
They have the same slope.
Here are 2 examples
y = 3x + 5
y = 3x + 19
The slopes are both three. The y intercepts are 5 for the top equation and 19 for the bottom equation.
They are both lines. That means their domain is -infinity <x < + infinity
Their range is - infinity <y < + infinity.
We are excluding examples like x = 3 and x = 5 and y = 1 and y = 3.
It is true that they both are parallel in both cases, but the discussion for each pair is a little different.
Answer:
an = 3n +4
Step-by-step explanation:
Eliminate parentheses and combine terms.
an = 7 + 3n -3
an = 3n +4
Answer:
length = cm
Step-by-step explanation:
Perimeter is the sum of the length of all of the sides of a figure. A rectangle has 2 pairs of sides with equal length, which is a 4 sides. Two of those sides have the measure of the width and the other 2 sides have the measure of the length. Since we know the width is , we can multiply that value by 2 (since 2 of the sides are long) and subtract it from the perimeter, 13:
The sum of the 2 sides that have the measure of the length is cm. To find the length, divide the measure by amount of sides:
÷ 2 =
The length is cm.
