Write and solve an equation to find the number n. Six times the sum of a number and 15 is -42.
Answer:
8
Step-by-step explanation:
6*(n + 15) = -42
Divide both sides by 6
6*(n - 15)/6 = -42/6
n - 15 = -7
n = -7 + 15
n = 8
The equation is solved and the number is n = -22
Given data ,
The sum of a number and 15 can be written as (n + 15)
Six times the sum of a number and 15 can be expressed as 6(n + 15).
According to the given information, this expression is equal to -42. So, we can write the equation:
6(n + 15) = -42
To solve for n, we need to simplify and isolate the variable.
Distribute 6 to the terms inside the parentheses:
6n + 6(15) = -42
Simplify:
6n + 90 = -42
Next, we want to isolate the variable term. Subtract 90 from both sides of the equation:
6n + 90 - 90 = -42 - 90
Simplify:
6n = -132
Finally, divide both sides of the equation by 6 to solve for n:
n = -132 / 6
Simplify:
n = -22
Hence , the number n is -22

y=-7x-2 through (-4,6)
what is the equation in slope-intercept form?
Answer:
the equation that passes through this is y= -7x-22
Step-by-step explanation:
You want to find the equation for a line that passes through the point (-4,6) and has a slope of -7.
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
To start, you know what m is; it's just the slope, which you said was -7. So you can right away fill in the equation for a line somewhat to read:
y=-7x+b.
Now, what about b, the y-intercept?
To find b, think about what your (x,y) point means:
(-4,6). When x of the line is -4, y of the line must be 6.
Because you said the line passes through this point, right?
Now, look at our line's equation so far: b is what we want, the -7 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specifically passes through the point (-4,6).
So, why not plug in for x the number -4 and for y the number 6? This will allow us to solve for b for the particular line that passes through the point you gave!.
(-4,6). y=mx+b or 6=-7 × -4+b, or solving for b: b=6-(-7)(-4). b=-22.

5/3
sqrt(5)
greatest: 2.5
Step-by-step explanation:

What is the number?A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.
As we know,
The integer can be defined as the whole number it can be a negative whole number or a positive whole number for example 2, 4, 1, -8, 0, etc.
It is defined as the numbers in all real numbers which cannot be represented as rational numbers, in other words, the irrational number cannot be expressed in the form of p/q form.
A rational number is a sort of real number that has the form p/q and does not equal zero.
Thus, the least to greatest order is √9/4, 5/3, √5, and 2.5 after simplification the numbers.

Step-by-step explanation:
A function is defined as a relation between a set of inputs having one output each.
The values of the function r(x) at x = -2, 0 and 5 are -5, -7, and -12.
What is a function?A function is defined as a relation between a set of inputs having one output each.
The inputs are called the domain of the function.
The outputs are called the range of the function.
We have,
A function r(x)
r(x) = x - 7
The value of r(x) at x = -2:
r(-2) = - ( -2) - 7
r(-2) = 2 - 7 = -5
The value of r(x) at x = 0:
r(0) = -0 - 7 = -7
The value of r(x) at x = -2:
r(5) = -5 - 7 = -12
We see that,
Domain = -2, 0, and 5.
Range = -5, -7, and -12.
Thus,
The values of the function r(x) at x = -2, 0 and 5 are -5, -7, and -12.

[tex]15x=10x+15[/tex]
Subtract 10x from both sides:
[tex]15x-10x=10x+15-10x[/tex]

Given the function f(x) = –5|x + 1| + 3, for what values of x is f(x) = –12?
Answer:
x = 2, -4
Step-by-step explanation:
To find the answer to this question, we will have to find the values of x where:
-5|x + 1| + 3 = -12
We can solve this equation for x to find the values of x that satisfy this equation.
-5|x + 1| + 3 = -12
Subtract 3 from both sides.
-5|x + 1| = -15
Divide both sides by -5.
|x + 1| = 3
Now here, the equation will split off into two different equations. These two are:
x + 1 = 3
x + 1 = -3
Lets solve the first one first.
x + 1 = 3
Subtract 1 from both sides.
x = 2
Now we solve the second one.
x + 1 = -3
Subtract 1 from both sides.
x = -4
So now we have the answers x = 2 and x = -4.
So the values of x are x = 2, -4
I hope this helps.

There are 680 raisins in 8 bags. If each bag has the same number of raisins, how many raisins are in 12 bags? a. 900 raisins b. 935 raisins c. 1,020 raisins d. 1,056 raisins
Answer:
C
Step-by-step explanation:
We can divide the number of raisins by 8 because there are 8 bags (680÷8) which would be 85. Next we multiply the 85 by 12 because we need to find out the number of raisins in 12 bags (85×12), which would give us 1,020.
