Answer:

Perimeter is sum of all side,

Step-by-step explanation:

=2X+7 + 6X-5 + 4X+1

=12X+3

BUT VALUE OF X IS NOT GIVEN IN QUESTION

Answer:

9

Step-by-step explanation:

since all the sides are equal, set two of the sides equal to each other. I did 2x+7 = 6x-5

6x-2x = 7+5

4x = 12

x = 3

Then you multiply 3 by 3 because it is an equilateral. And you get 9.

I not a 100 percent sure. Hope this helped.

Only column 3 - Trina's numbers represent proportional relationship

Equation for it is: y = 2.5x

Calculation is provided on the table

Answer:

the answer is x equals 22 and y equals 8

Step-by-step explanation:

first equation is x+y=30

Second equation is x-y/2=7 that simplify's to x-y=14

then you add then so they will cancel out and you are left with 2x=44 so divide two by both sides which gives x=22

then you subsitute the 22 in the first equation. It will be 22+y=30 then you subtract 22 from the 30 that gives you y=8

so the two numbers are 22 and 8

Hope this helps!!!!

The numbers satisfying the given conditions are 22 and 8.

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

We have the following problem -

Two numbers have a sum of 30. Half of their difference is 7.

We can write the equations as -

x + y = 30

1/2(x - y) = 7

Rearranging, we get -

y = - x + 30

y = x - 14

Plot the graph, the point of intersection is the solution. The number will be 22 and 8.

y = - x + 30

y = x - 14

Equating both, we get -

- x + 30 = x - 14

30 + 14 = 2x

2x = 44

x = 22

and

y = 22 - 14

y = 8

Therefore, the numbers satisfying the given conditions are 22 and 8.

Answer:

(x+8)(5x2−2)

Step-by-step explanation:

Hope this helps have a nice day :)

Answer:

Proportionality constant can be used with any representation to determine how a variable is changing with respect to others.

Variation is a method comparing the nature of a variable with another variable using a constant called the proportionality constant

For instance, if a variable y is directly proportional to x, it is expressed as;

y ∝ x

y = kx

k is the proportionality constant relating y to x and shows that as the value of y is increasing, the value of x is also increasing and vice versa.

Answer: y= 25+2.5x

Step-by-step explanation:

Let a = base pay , b = additional amount per newspaper.

Given: Last week, Pedro delivered 5 newspapers and earned $37.50.

i.e. 37.50=a+5b      (i)

This week, he delivered 20 newspapers and earned $75.

i.e. 75=a+20b         (ii)

Eliminate (i) from (ii)

37.50=15b

[tex]\Rightarrow\ b=\dfrac{37.50}{15}\\\\\Rightarrow\ b=2.5[/tex], i.e. additional amount per newspaper= $2.5

Put b= 2.5 in (i)

[tex]37.50=a+5(2.5)\\\\\Rightarrow\ 37.50=a+12.5\\\\\Rightarrow\ a=37.50-12.5\\\\\Rightarrow\ a=25[/tex], i.e. base pay = $20

Let x= Number of newspapers Pedro delivers.

y=  Earnings he receives in dollars.

y= 25+2.5x will be the required function.

Answer:

3 solutions

Step-by-step explanation:

To solve g(x) = 2

The solutions are at the points of intersection of g(x) and y = 2

y = 2 is the equation of a horizontal line parallel to the x- axis and passing through all points with a y- coordinate of 2

If you draw the horizontal line using say (0, 2) and (2, 2)

Then g(x) intersects y = 2 at 3 places

Thus there are 3 solutions to g(x) = 2

Answer:

(x^4) - 64x

Step-by-step explanation:

zeros at 4 and 0 are the roots so can be factor as x*(x-4) and the multiplicity tels to what power you have to raise those factors

[tex]x^{1} *(x-4)^{3}[/tex] becuase multiplicity of 1 for root at 0, and multiplicity of 3 at root 4

now to write this in standard form

[tex]x*(x-4)^{3} = \\x*(x-4)(x^{2} +4x+16)= \\(x^{2} -4x)(x^{2} +4x+16) = \\x^{4} +4x^{3} +16x^{2} -4x^{3} -16x^{2} -64x = \\x^{4} -64x[/tex]

Step-by-step explanation:

7x÷2+5=8

divide by 2 on both sides:

7x/2+5=8(it's a fraction)

subtract 5 on both sides

7x÷2=3

multiply 2 on both sides

7x=6

divide by seven on both sides

x=6/7

Answer:

Step-by-step explanation:

Bowls of Punch = 6

Each bowl holds 2 1/2 gallons of punch

6 bowls = 2 1/2 gallons × 6

= 5/2 × 6 gallons

= 30/2

= 15 gallons

6 bowls of Punch = 15 gallons of Punch

1 gallon = 4 quarts

15 gallons = 4 × 15 quarts

= 60 quarts

6 bowls of Punch = 15 gallons of Punch = 60 quarts of punch

She thinks each person will drink about 1 quart of punch.

How many people will the 6 bowls of punch serve?

6 bowls of Punch = 15 gallons of Punch = 60 quarts of punch

60 quarts of punch / 1 person

= 60 people

The 6 bowls of punch will serve 60 people
