y = x +13 solve for x if y =5
Answer:
If you were solving for x, then it would be -8. If you were solving for why it would be 18.
Step-by-step explanation:
-6(-2n - 2) - 8(5 + 4n) = -2n - 11n
Answer:
n= -4
Step-by-step explanation:
-20n-28=-13n
-20n=-13n+28
-20n+13n=28
-7n=28
n=-4

When multiplying two negative integers what what is the sign of the product
A menu has 5 choices of appetizers, ten main courses, and seven desserts. How many meals are possible?
Using the Fundamental Counting Theorem, it is found that 350 meals are possible.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
Considering the menu described in the problem, we have that:
[tex]n_1 = 5, n_2 = 10, n_3 = 7[/tex].
Hence the number of meals possible is given by:
N = 5 x 10 x 7 = 350.

Percy has $100 in a savings account. The interest rate is 5% per year and is not compounded. How much will he have in 1 year?
Answer:The compound interest formula is an equation that lets you estimate how much you will earn with your savings account. It's quite complex because it takes into consideration not only the annual interest rate and the number of years but also the number of times the interest is compounded per year.

This table gives a few (x,y) pairs of a line in the coordinate plane.
x y
48 -30
61 -45
74 -60
What is the x-intercept of the line?
Answer:
22
Step-by-step explanation:
First, find the equation of the line in slope-intercept form, y = mx + b.
Using the coordinates of these two pairs, (48, -30) and (61, -45), the slope (m) can be calculated as follows:
[tex] m = \frac{y_2 - y_2}{x_2 - x_1} = \frac{-45 -(-30)}{61 - 48} = \frac{-15}{13} [/tex]
[tex] slope (m) = -\frac{15}{13} [/tex]
Find the y-intercept (b) by substituting x = 48, y = -30, and [tex] m = -\frac{15}{13} [/tex] into y = mx + b:
[tex] -30 = -\frac{15}{13}(48) + b [/tex]
Solve for b.
[tex] -30 = -\frac{720}{13} + b [/tex]
Add [tex] -\frac{720}{13} [/tex] to both sides
[tex] -30 + \frac{720}{13} = b [/tex]
[tex] \frac{-390 + 720}{13} = b [/tex]
[tex] \frac{330}{13} = b [/tex]
[tex] b = \frac{330}{13} [/tex]
Substitute [tex] m = -\frac{15}{13} [/tex] and [tex] b = \frac{330}{13} [/tex] into y = mx + b
[tex] y = -\frac{15}{13}x + \frac{330}{13} [/tex]
The x-intercept of the line with the above equation, would be the value of x when y = 0. This is the value of x where the line cuts across the x-axis. To calculate this, substitute y = 0 into [tex] y = -\frac{15}{13}x + \frac{330}{13} [/tex].
[tex] 0 = -\frac{15}{13}x + \frac{330}{13} [/tex]
Subtract [tex] \frac{330}{13} [/tex] from both sides
[tex] -\frac{330}{13} = -\frac{15}{13}x [/tex]
Divide both sides by [tex] -\frac{13}{15}x [/tex]
[tex] \frac{-\frac{330}{13}}{-\frac{13}{15}} = x [/tex]
[tex] -\frac{330}{13}*-\frac{13}{15} = x [/tex]
[tex] -\frac{330}{1}*-\frac{1}{15} = x [/tex]
[tex] \frac{330}{15} = x [/tex]
[tex] 22 = x [/tex]
The x-intercept = 22
