Answer:Assuming the problem is for the linear functions:

f(x) = -1-50-113 g(x) = -51-113*(2x-7) = -226x+740  

g(x) = 2x-7

Step-by-step explanation:

Answer:

x = 20

Step-by-step explanation:

2(x - 5) = 9 - 3x + 6 + 8 + 3x + 7

2x - 10 = 9 - 3x + 6 + 8 + 3x + 7

2x = 10 + 6 + 8 + 7 + 9

2x = 40

x = 40 ÷ 2

x = 20

Thus, x = 20

Hope it helps if it does pls give me brainly :)

Answer:

y>1/3x-3

Step-by-step explanation:

Answer:

Step-by-step explanation:

m = [tex]\frac{rise}{run}[/tex] = [tex]\frac{1}{3}[/tex]

y-intercept is (- 3)

y > [tex]\frac{1}{3}[/tex] x - 3

Answer:

it would be 16u2-81s2 using a2-b2 formula

Answer:

She is correct because 30 percent of 30 is 9 or in other words if you multiply 30 by 30 percent you get 9.

Step-by-step explanation:

Answer:

Yes she is correct cause 30 times 30 percent is 9

Step-by-step explanation:

Answer:

Explained below.

Step-by-step explanation:

(A)

Use two-point form to determine the equation for the total monthly cost of the NextFell plan.

[tex](y-y_{1})=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\cdot (x -x_{1})\\\\(y-247)=\frac{247-114}{640-260}\cdot (x-640)\\\\(y-247)=0.35x-224\\\\y=0.35x+23[/tex]

(B)

Compute the total monthly cost if 949 minutes are used as follows:

[tex]y=0.35x+23\\\\=(0.35\times 949)+23\\\\=355.15[/tex]

Thus. the total monthly cost if 949 minutes are used is $355.15.

Answer:

Step-by-step explanation:

If the age of a cat is represented by 'x' and human years by 'y', relation between the age of cat and human years will be,

y = 4x + 16 [multiplying cat's age by 4 and by adding 16]

Now from the given table,

If x = 2,

y = 4×2 + 16

  = 24

If y = 3,

y = 4×3 + 16

  = 28

If x = 4,

y = 4×4 + 16

  = 32

If x = 5,

y = 5×4 + 16

  = 36

If x = 6,

y = 6×4 + 16

  = 40

Cat age             2            3           4            5            6

Human years   24          28        32          36          40

Answer: So if you do 50 dollars - 70% you get, 15 U.S. dollars

Hope this helps :)

Step-by-step explanation:

Answer:

Step-by-step explanation:

Divide 100 by 16 and you get 6.25 then turn it into a mixed number which would be 6 25/100 then reduce 25/100 by dividing 100 by 25 and 25 by 25 which will give you 1/4 so the answer is 6 1/4.Welcome!

Answer:

8m > 4

Step-by-step explanation:

8m, (the amount of money Demarcus has), is more than how much money his older sister has, (4), so 8m is greater than (>) 4

Answer: 17

Step-by-step explanation:

2x + 56=22

- 56 -56

2x = -34

divide 2x by both sides

x = -17

Answer:

Step-by-step explanation:

Given the equation

[tex]\frac{1}{5}x-\frac{2}{3}y=30[/tex]

putting y=15

[tex]\frac{1}{5}x-\frac{2}{3}\left(15\right)=30[/tex]

[tex]\frac{1}{5}x-10=30[/tex]

add 10 to both sides

[tex]\frac{1}{5}x-10+10=30+10[/tex]

[tex]\frac{1}{5}x=40[/tex]

[tex]x=200[/tex]

Therefore, the value of x:

Answer:

Step-by-step explanation:

Answer:

if you ment to say 2 is 12.5% of what number the answer would be 16

Step-by-step explanation:

Write down what you know with x as the number you need to find.

Of is always "multiply"

Choose another way to write 12.5%

2 =12.5% of x

So 2 = 0.125xx

x= 2 *over*0.125

x=16

Answer:

x=16

Step-by-step explanation:

Let the number be x.

if they say 12.5% of a number, this means that 12.5/100 *x which will be :

12.5/100x

make it an equation (a true one)

12.5/100x=2

divide.

2 divided by 12.5/100x would be

x=16!

Cheers, I hope you can understand it well!

add the odes and sonnets, and find the percentage of 78/124 which is 62.9% rounded to 63%.

Answer:

∠AMC  = 75

Step-by-step explanation:

ΔABC,

∠C = 90°  ; ∠B = 30°

∠A + ∠B +∠C  = 180   {Angle sum property of triangle}

∠A + 30 + 90 = 180

       ∠A + 120 = 180

                 ∠A = 180 - 120

                 ∠A  = 60°

In ΔACM,

∠ACM = 90/2  =  45°         { CM is angle bisector}

∠ACM + ∠AMC +∠A =  180   {angle sum property}

   45 +  ∠AMC + 60 = 180

            ∠AMC + 105 = 180

                     ∠AMC = 180 - 105

∠AMC  = 75

the reciprocal of 1/3 is 3

the opposite of 3 = -3

Answer: It would be B 9/50

Step-by-step explanation: if you take 3/7 and x it by 0.1 you get 0.04285714285 and then if you divide that by 5/21 you get 0.18 which equals 9/50 as a fraction
