Answer:

7% was the interest rate

Answer:

y=0

Step-by-step explanation:

Simplifying

y + y = 0

Combine like terms: y + y = 2y

2y = 0

Solving

2y = 0

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Divide each side by '2'.

y = 0

Simplifying

y = 0

Answer:

The correct answer is,

Answer:

y = 4/5x

y = 4/5x - 3.2

Step-by-step explanation:

The equation for slope is y=mx+b, the mx stands for the slope which is 4/5x. The b stands for where the line goes through the y axis, in this equation the first line crosses the y axis at the origin (0) and the second one crosses at -3.2, these are also called y-intercepts because they intercept the y axis.

Answer:

There are 102 children

Step-by-step explanation:

Let us solve the question

∵ There are 272 people in an audience

∴ The total number of people = 272

∵ The ratio of adults to children is 5: 3

→ Find the sum of the two parts of the ratio

∴ The sum of the parts of the ratio = 5 + 3 = 8

→ By using the ratio method

→  Adults:  Children:  People

→  5        :   3            :  8

→  A        :   C           :  272

→ By using the cross multiplication

∵ C × 8 = 3 × 272

∴ 8C = 816

→ Divide both sides by 8

∴ C = 102

∵ C represents the number of children

∴ There are 102 children

Answer:

(-10; 60)

Step-by-step explanation:

y = -6x

(12; -2)

-2 = -6 · 12

-2 = -72 - no

(3; -9)

-9 = -6 · 3

-9 = -18 - no

(-10; 60)

60 = -6 · (-10)

60 = 60 -  yes

(18; -3)

-3 = -6 · 18

-3 = -78 - no

Answer:

37 degrees

Step-by-step explanation:

Answer: (x+4)(x−9)

Step-by-step explanation:

Answer:

(X - 9) is one factor

(X + 4) is the other factor

Step-by-step explanation:

You can factor polynomials with guess work or with polynomial division

To factor using guess work search for a number that will multiply with -9 to equal -36 and add with -9 to equal -5.

In order for -9 to add with another number and equal -5 you need to add 4 to it. And because -9 will multiply with 4 to equal -36 as well, 4 is confirmed to be the other factor. You can write out the factor as (x + 4)

[tex] \sf \dfrac{24}{2} = \dfrac{t}{7} [/tex]

[tex] \sf \dashrightarrow \:\dfrac{24}{2} = \dfrac{t}{7} [/tex]

[tex] \sf \dashrightarrow \: \cancel{\dfrac{24}{2}} = \dfrac{t}{7} [/tex]

[tex] \sf \dashrightarrow \:12 = \dfrac{t}{7} [/tex]

[tex] \sf \dashrightarrow \:12 \times 7 = t[/tex]

[tex] \sf \dashrightarrow \:84 = t[/tex]

[tex] \sf \dashrightarrow \:t = 84[/tex]

Answer: Variable: y= Number of sour straws.

Inequality: 7.50+1.50y ≤ 15

Solution: y ≤ 5

Step-by-step explanation:

Let  y= Number of sour straws.

Cost for nachos = $7.50

Cost per sour straw = $1.50

Total cost = 7.50+1.50y

Money he has $15

Total cost must be less than orequal to the money he has.

So required inequality: 7.50+1.50y ≤ 15

Subtract 7.50 from both sides

[tex]1.5y\leq 7.5\\\\\Rightarrow\ y\leq\dfrac{7.5}{1.5}\\\\\Rightarrow\ y\leq 5[/tex]

He can buy at most 5 sour straws.

Answer:

16 + 104 = 120 square inches

Step-by-step explanation:

13 x 8 = 104

17 - 13 = 4

4 x 8 =32

32 divided by 2 is 16

so 16 +104 = 120

None of them is right.

The concept of proportionality in mathematics denotes the linear relationship between two numbers or variables. The size of one item increases by twofold, whereas the size of the other quantity decreases by one-tenth of the earlier amount.

Given a table that has work and time spent on that theoretical work has to be proportional to the time such as the Spend time ∝ number of pages read but none of the options match the criteria. Therefore no option is correct for this problem.

Answer: Eva's dog actually gained 3/8 pounds ( 0.375pounds)

Step-by-step explanation:

Step 1

Given that

old weight = 1 7/8  pounds

New weight = 2 1/4 pounds

weight gained = New weight - Old weight

Step 2

 weight gained = New weight - Old weight

                  2 1/4  pounds - 1 7/8 pounds

      2.25 pounds - 1.875 pounds

         0.375pounds = 3/8 pounds

Answer:

Yes, (2, 10) is a solution to this system:

y = 4x + 2

y = x + 8

Step-by-step explanation:

When graphed, the two equations cross at (2,10) making it a solution.

Answer:

Yes

Step-by-step explanation:

If y=4x+2 and y=x+8, then 4x+2=x+8

4x+2=x+8

4x=x+6

3x=6

x=2

Plugging this into the original equation "y=x+8", we obtain the result that y=10.

This means, (2, 10) is a solution  to the system.
