Which ordered pair is the solution to the system of equations? {−3x+4y=−20y=x−4 (−4, −8) (4, 8) (−2, −6) (0, −5)

Answer: -4c+12

all real numbers

Step-by-step explanation:

6) 28-(3c+4) =2 (c+6)+c

When there is a - in front of an expression in parentheses , change the sign of each term of the expression.

28-3c-4=2(c+6)+c

Distribute 2 through the parentheses

28-3c-4=2c+12+c

Now we do the same thing only different way

2(c+6)

Multiply each term in the parentheses by 2

2c+2×6

Multiply the numbers

2c+12

_____________

28-3c-4=2c+12+c

subtract the numbers

24-3c=2c+12+c

Collect like terms

24-3c=3c+12

It's the same thing only different way ok

2c+c

If a term doesn't have a coefficient , it is considered that the coefficient is 1.

2c+1c

Collect like terms by adding their coefficients

(2+1)c

Add the numbers

3c

________

24-3c=3c+12

Move variable to the left hand side and change its sign

24-3c-3c=12

Move constant to the right  by adding its opposite to both sides

-3c-3c+24-24=12-24

eliminate the opposites

-3c-3c=12-24

Collect like terms

-6c=12-24

Calculate the difference

-6c=-12

so the same thing only different way ok

12-24

Keep the sign of the number with the larger absolute value and subtract the smaller absolute value from the larger.

-(24-12)

Subtract the numbers

-12

__________

-6c=-12

divide both sides of the equation by -6

-6c÷(-6)=-12÷(-6)

Any expression divided by itself equals 1

c=-12÷(-6)

Dividing two negatives equals a positive

(-)÷(-)=(+)

c=12÷6

Calculate the quotient

c=2

Step-by-step explanation:

14. Question wise,

In ΔRST,

∠R=2x+5

∠S=x+1

∠T=7x-16

we know,

∠R+∠S+∠T=180 [sum of 3 angles of a triangle is 180°]

2x+5+x+1+7x-16=180

10x-10=180

10(x-1)=180

x-1=18

x=19

so,

∠R=(2×19)+5=43

∠S=19+1=20

∠T=(7×19)-16=117

15. Question wise,

In ΔABC,

∠A=∠C-13

∠B=4∠C-11

we know,

∠A+∠B+∠C=180 [,,]

∠C-13+4∠C-11+∠C=180

6∠C-24=180

6∠C=180+24

∠C=204÷6=34

so,

∠A=34-13=21

∠B=(4×34)-11=125

16. Question wise,

In ΔJKL

∠K=∠J+9

∠L=2∠J-21

we know,

∠J+∠K+∠L=180

∠J+∠J+9+2∠J-21=180

4∠J-12=180

4∠J=180+12

∠J=192÷4=48

so,

∠K=48+9=57

∠L=(2×48)-21=75

Answer:

46. or 45.5 if not rounded

Step-by-step explanation:

We know she makes $72.85 at selling cookies if she sales 17 cupcakes for $3.25 she'll make $55.25 but were trying to find how many she sales with $1.60 so $72.85 divided by 1.60 is 45.5 and if not then it's 46. rounded.

Answer:

FV= $22,536.5

Step-by-step explanation:

Giving the following information:

Growth rate (i)= 1% monthly

Present value (PV)= $20,000

Number of periods= 12 months

To calculate how much will the employee earn after a year, we need to use the following formula:

FV= PV*(1+i)^n

FV= 20,000*1.01^12

FV= $22,536.5

I need to see answer choices, but things that don’t describe a slop is anything that aren’t points, graphs or tables.

Step-by-step explanation:

If you show the answers I can tell you the exact answer.

Answer:

Please provide answer choices. As I have nothing to look off of, I cannot answer accurately. However, I can provide a definition to the word, "slope".

Explanation:

The equation for slope can most often be written out as y=mx+b, where m is the slope, and b is the intercept. The slope of a line is the number that shows the rise and run of the line.

2/5

Answer:

[tex]P=150+150t[/tex]

Step-by-step explanation:

Let P denotes the total cost and t denotes the time.

Total cost for 2 hours = $300

So,

Cost for 1 hour = [tex]\frac{300}{2} =\$150[/tex]

Also,

Fixed fee to use the studio = $150

The studio charges an initial studio-use fee plus an hourly fee for each hour in the studio.

Therefore,

Total cost = Fixed fee to use the studio + Hourly fee for each hour in the studio

[tex]P=150+150t[/tex]

Your small pepperoni pizza would need to bake for 19 minutes

Step-by-step explanation:

Since the small pepperoni pizza has to bake 7 minutes longer that a small plain pizza which takes 12 minutes all you have to do is add 12 + 7

Answer:

B

Step-by-step explanation:

So from the first graphs equation is

2x-y=-1

therefore if we made y the subject of the formula, the equation would be

2x+1=y , this is also the same as y=2x+1

from this, the equation is clearly in the form y=mx+c so we can get the gradient

The gradient of graph one would be 2

The perpendicular gradient would be the negative reciprocal of graph one's gradient which would be -1/2

Now we look at our options and see which one has the gradient as -1/2

Using linear function concepts, it is found that the equation parallel to 2x - y = -1 is given by:

C. y − 1 = 2(x − 3)

The equation of a line has the following format:

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

The equation of the line given is:

[tex]2x - y = -1[/tex]

[tex]y = 2x + 1[/tex]

Which has slope [tex]m = 2[/tex]

If we look at option C:

[tex]y - 1 = 2(x - 3)[/tex]

[tex]y = 2x - 6 + 1[/tex]

[tex]y = 2x - 5[/tex]

It also has slope of [tex]m = 2[/tex], the same as the line given, thus, they are parallel.
