Step-by-step explanation:

solve for c: 16c - 7 = 13.32

Answers

16c - 7 = 13.32

16c = 13.32 + 7

16c = 20.32

c = 20.32/16

c = 1.27

solve for x: 5x - 2 = 3x + 8

Answers


5x-2=3x+8


X=5

That's your answer

Answer:

x = 5

Step-by-step explanation:

To solve for x in 5x - 2 = 3x + 8 start by getting the variables on the same side. To do this, subtract 3x from 5x. (you always do the opposite of the term's operation)

2x - 2 = 8 now add 2 to 8

2x = 10 now divide 2

x = 5

Answer:

A and D are functions

Step-by-step explanation:

A is a function because each output is going down the same amount each time, in this case, going down by 4. (the function here is y = -x + 11)

B is not a function because there isn't a constant for y.

C isn't a function either because two x's are 0 with different y values, and you can't have that in a function.

D is also a function because of the equation on the right side.

The red line of the attachment below in A's function graphed, and the lime curve represents D's function graphed.

What is the equation of the line that has a slope of m = 2 and passes through the point (-5, -6)?

Answers

Answer:

[tex]y=2x+4[/tex]

Step-by-step explanation:

You can solve this two ways: insert the values into point-slope form and simplify to solve for y, converting it to slope-intercept form, or insert the values into slope-intercept form, solve for b, and insert b. We'll do both :)

Point-slope form:

[tex]y-y_{1}=m(x-x_{1})[/tex]

Where:

[tex]m[/tex] is the slope[tex]x_{1}[/tex] and [tex]y_{1}[/tex] are corresponding coordinate points [tex](x,y)[/tex]

Insert the given values:

[tex]m=2\\\\(-5_{x_{1}},-6_{y_{1}})\\\\y-(-6)=2(x-(-5))\\\\y+6=2(x+5)[/tex]

Solve for y. Expand the right sie using the distributive property:

[tex]y+6=2(x)+2(5)\\\\y+6=2x+10[/tex]

Isolate the variable. Subtract 6 from both sides, canceling out the 6 on the left:

[tex]y+6-6=2x+10-6\\\\y=2x+4[/tex]

OR

Slope-intercept form:

[tex]y=mx+b[/tex]

Where:

[tex]m[/tex] is the slope[tex]b[/tex] is the y-intercept[tex]x[/tex] and [tex]y[/tex] are corresponding coordinate points [tex](x,y)[/tex]

Insert the given values:

[tex]m=2\\\\(-5_{x},-6_{y})\\\\-6=2(-5)+b[/tex]

Simplify the multiplication:

[tex]-6=-10+b[/tex]

Solve for b. Add 10 to both sides, canceling out the 10 on the right:

[tex]-6+10=-10+10+b\\\\4=b[/tex]

The value of b is 4. Insert the appropriate information into the equation. When using slope-intercept form, you don't plug in the coordinate points:

[tex]y=2x+4[/tex]

:Done
