Answer:
<em>the desired new equation is y = -3x - 5</em>
<em />
Step-by-step explanation:
The desired equation of this new (parallel) line has exactly the same form as the given line y = -3x - 7. Only the y-intercept will be different.
Starting with y = -3x - 7, replace x with the x-coordinate of the given point (1, -8) and y with the y-coordinate. We get:
-8 = -3(1) + C, where C is the new y-intercept and is to be determined.
Then C = -5, and <em>the desired new equation is y = -3x - 5</em>.
Answer:
The number of months cost same is 9
Step-by-step explanation:
Given:
Equation for the first plan y = 38x + 15
Equation for the second plan y = 31x + 78.
where x is the number of month
Solution:
38x + 15 = 31x + 78
7x + 15 = 78
7x = 63
x = 9
Answer:
1/18.
Step-by-step explanation:
P(A) = 1/3 (as there are 3 cards with one marked A).
P(3 on the die) = 1/6 (as there are 6 sides on a die).
P(A then 3) = 1/3 * 1/6 = 1/18.
Note: the probabilities are multiplied because the 2 events are independent.
n^3 + 6
I'll make n stand for the number
Six more means adding extra 6 onto our number cubed.
So, n x n x n = n^3
(n^3 means n cubed)
Thus, answer is n^3 + 6

We can represent the pizza as 1. And every time we take a slice, we take percentage away. This pizza is cut up equally into 10 slices. So, if we take away a slice, we take away 1/10 of the pizza. What if Sally ate 6 slices? Same difference. She took away 6/10 of the pizza.
And to answer the question, "What <span>percentage of the pizza did Sally eat if she had six slices?"
We will convert the 6/10 into a percentage. First convert the fraction into a decimal then into a percent.
To convert a fraction into a decimal, simply divide it's numerator by it's denominator.
6/10 = 0.60
And to convert a decimal into a percentage, move the decimal point two places to the right and change it into a % sign.
0.60 = 60%
So, the answer to this question C) 60%
