can someone help me with this please

Answer:

  (-1, 3)

Step-by-step explanation:

Only the first question is complete.

You want to solve ...

  2x +y = 1

  3x -y = -6

You can add these two equations to get ...

  5x = -5

  x = -1 . . . . . divide by 5

This matches the first choice: (-1, 3).

Answer:

A: (-1,3) is the correct answer to the problem.

Step-by-step explanation:

Answer:

A   x < 3

Step-by-step explanation:

[tex]\frac{5(9-x)}{3} + 1 < 11[/tex]

[tex]\frac{5(9-x)}{3} < 11 - 1[/tex]

[tex]\frac{5(9-x)}{3} < 10[/tex]

5(9-x) < 10*3

5(9-x) < 30

9-x < 30/5

9-x < 6

-x < 6 - 9

-x < -3

x < 3

Answer:

9

Step-by-step explanation:

If three magazines cost $15 then that means that each magazine costs $5. So we do 5 divided by 45 which equals 9. SO the answer is 9!

Answer:

44%

Step-by-step explanation:

Suppose the original number is 100.

It is increased by 20 %, so the result will be 120.

The resulting number is again increased by 20%, which is increased by 120 *20/100, which is increased by 24. The final result will be 120+24 that is 144.

The final result is increased by 44 compared to the original number 100.

So, increase by 44%.

Answer:

1/4

Step-by-step explanation:

The probability that the number rolled is 3 is, 1/4.

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Given that;

A die is tossed.

And, The number rolled is greater than 2.

Here, The number rolled is greater than 2.

Hence, Total outcomes are 3, 4, 5, 6

So, The probability that the number rolled is 3 is,

⇒ 1 / 4

Answer:

Step-by-step explanation:

We are expected to solve for the change given the following values of x

0,h

so we substitute x= 0 and x=h in the given expression, get the result, and subtract the results from each other

for x=0

[tex]g(x) = 4 x + 7\\\\g(0)=4(0)+7\\\\g(0)=0+7\\\\g(0)=7[/tex]

for x=h

[tex]g(x) = 4 x + 7\\\\ g(h)=4(0)+7 \\\\g(h)=4h+7 \\\\g(h)=4h+7[/tex]

The change would be

[tex]g(h)-g(0)= (4h+7)-7\\\\g(h)-g(0)= 4h+7-7\\\\g(h)-g(0)= 4h[/tex]

Step-by-step explanation:

Answer:

x + y = 103 Subtract 2nd from 1st EQ

-10y = -90

y = 9 and x = 94 9%2A9%2B13

and...checking

sum = 103

Step-by-step explanation:

The two numbers are 9 and 94.

In mathematics, a set of simultaneous equation, also known as a system of equations or an equation system, is a set of equations for which common solutions are sought.

Let the two numbers be x and y.

Then according to question,One number is 13 more than the product of 9 and another number we have ,

13 + 9x = y  

or,9x - y = -13...(i)

Also,the sum of the two numbers is 103. So we have,

x + y = 103 ...(ii)

Adding equation (i) and (ii) we get,

10x = 90

or, x = 9

Put the value of x in equation (ii), we get

9 + y = 103

or, y = 103 - 9

or, y = 94

Hence the two numbers are 9 and 94.

Answer:

4n-8

Step-by-step explanation:

With n representing the unknown number.

The expression that represents "8 less than the product of 4 and a number" will be 4n - 8.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

Translate this phrase into an algebraic expression. 8 less than the product of 4 and a number.

Let the number be n.

Then the product of 4 and n will be 4n.

Then the expression that represents "8 less than the product of 4 and a number" will be

4n - 8

The expression that represents "8 less than the product of 4 and a number" will be 4n - 8.

Answer:

[tex]d = 2\sqrt{145}[/tex]

Step-by-step explanation:

Use the Distance Formula to help you determine the distance between the two following points ( [tex](-12, 1)[/tex] and [tex](12, -1)[/tex] ):

-Distance Formula:

[tex]d = \sqrt{(x_{2} - x_{1}) ^2 + (y_{2} - y_{1})^2}[/tex]

(where [tex]( x_{1}, y_{1})[/tex] represents the first point, and [tex](x_{2}, y_{2})[/tex] represents the second point)

-Apply the following points to the equation:

[tex]d = \sqrt{(12 + 12) ^2 + (-1 - 1)^2}[/tex]

[tex]( x_{1}, y_{1})[/tex] = [tex](-12, 1)[/tex]

[tex](x_{2}, y_{2})[/tex] = [tex](12, -1)[/tex]

-Solve the equation:

[tex]d = \sqrt{(12 + 12) ^2 + (-1 - 1)^2}[/tex]

[tex]d = \sqrt{(24)^2 + (-2)^2}[/tex]

[tex]d = \sqrt{576 + 4}[/tex]

[tex]d = \sqrt{580}[/tex]

[tex]d = 2\sqrt{145}[/tex]

Therefore, the distance is [tex]2\sqrt{145}[/tex].

The probability that it is neither diet nor caffeine-free is 0.13.

Probability is the likeliness of an event to happen.

The number of total sodas = 100

The number of diet soda = 65

The number of Caffeine free sodas = 30

The number of caffeine free sodas out of diet sodas = 22

The number of soda that are neither caffeine nor soda is 100 -65-22 = 13

The probability that it is neither diet nor caffeine-free is 13/100 = 0.13
