Solve the system of equations down below Y-15=3x
-2+5y=-3

Answers

Answer 1

Answer:

Step-by-step explanation:

-5(y-15=3x) = -5y+75=-15x

add 15x to both sides and subtract 75 to both side

-5y+15x=-75

5y-2x=-3

13x=-78

and then both side divide by 13

x=-6

y-15=3(-6)

y-15=-18

Y= (-18) - 15 =  -3

y=-3

and the answer will be  (-6,-3)

hope that help you

Solving systems of equations using substitution/eliminationSolving systems of equations by graphing

Step-by-step explanation:

Step 1: Define Systems

y - 15 = 3x

-2x + 5y = -3

Step 2: Rewrite Systems

y - 15 = 3x

Add 15 to both sides:                    y = 3x + 15

Step 3: Redefine Systems

y = 3x + 15

-2x + 5y = -3

Step 4: Solve for x

Substitution

Substitute in y:                         -2x + 5(3x + 15) = -3Distribute 5:                              -2x + 15x + 75 = -3Combine like terms:                13x + 75 = -3Isolate x term:                          13x = -78Isolate x:                                   x = -6

Step 5: Solve for y

Define equation:                    y - 15 = 3xSubstitute in x:                       y - 15 = 3(-6)Multiply:                                  y - 15 = -18Isolate y:                                 y = -3

Step 6: Graph Systems

Check the solution set.

how do you find the domain and range on a graph

Answers

Look at the values on the axes of the graph.

Step-by-step explanation:

Domain can be found by looking at the x-axis of a graph. Range can be found by looking at the y-axis of a graph. You have to find at what point on the axis is the graph stopping.

For example, if I wanted the domain of y=x, I would say it is all real numbers. Why? Because when we look along the x-axis, from left to right, we can see that it continues going until infinity. That means that there are no stopping points in the graph of y=x.

Rani ate 2/7 of the cake while her brother ate 4/5 part of the remaining. part of the cake left is?​

Answers

Answer:

Nothing left

Step-by-step explanation:

Nothing left

2/7+4/5=38/35

1 3/35

Answer:

[tex]\frac{1}{7}[/tex]

Step-by-step explanation:

Amount of cake Rani ate = [tex]\frac{2}{7}[/tex]

You need to understand that her brother ate 4/5 of the remaining part, not of the entire cake, so we need to figure out the actual amount out of the entire cake first before calculating how much is left.

Amount of cake brother ate = [tex]\frac{4}{5}[/tex] × ([tex]\frac{7}{7}[/tex] - [tex]\frac{2}{7}[/tex])

                                               = [tex]\frac{4}{5}[/tex] × [tex]\frac{5}{7}[/tex]

                                               = [tex]\frac{4}{7}[/tex]

Amount of cake left = [tex]\frac{7}{7}[/tex] - [tex]\frac{2}{7}[/tex] - [tex]\frac{4}{7}[/tex]

                                 = [tex]\frac{1}{7}[/tex]

Which graph shows the solution set of the inequality 2.9 (x + 8) less-than 26.1

Answers

Answer:

the solution set of inequality 2.9 (x + 8) less-than 26.1 is [tex]x<1[/tex]

Option D is correct.

Step-by-step explanation:

We need to find the graph that shows the solution set of the inequality 2.9 (x + 8) less-than 26.1

First we will solve the inequality to find value of x

[tex]2.9 (x + 8) <26.1[/tex]

Divide both sides by  2.9

[tex]\frac{2.9 (x + 8)}{2.9} < \frac{26.1}{2.9} \\x+8 < 9[/tex]

Subtract both sides by -8

[tex]x+8-8<9-8\\x<1[/tex]

So, the solution set of inequality 2.9 (x + 8) less-than 26.1 is [tex]x<1[/tex]

The graph would be:

A number line goes from negative 10 to positive 10. An open circle appears at positive 1. The number line is shaded from positive 1 toward negative 10.

Option D is correct.

Answers

Answer:

[tex]B = 69[/tex]

Step-by-step explanation:

Given

[tex]A = 2x +27[/tex]

[tex]B = x +27[/tex]

Required

Determine B

First, we need to solve for x

Since both angles are supplementary, then

[tex]A + B = 180[/tex]

Substitute values for A and B

[tex]2x + 27 + x + 27 = 180[/tex]

Collect Like Terms

[tex]2x + x = 180 - 27 - 27[/tex]

[tex]3x= 126[/tex]

Divide through by 3

[tex]x = 42[/tex]

Recall that:

[tex]B = x +27[/tex]

Substitute 42 for x

[tex]B = 42 + 27[/tex]

[tex]B = 69[/tex]

the rate of interest of the investment.
(5 marks)​

Answers

Answer: 2=2

Step-by-step explanation:

Without any more information, it sounds like interest is compounded continuously, in which case the value of the investment A is given by

[tex]A=Pe^{rt}[/tex]

where P is the principal investment, r is the interest rate, and t is the number of years.

At the end of the second year (t = 2), the value is A = 60,500, and after the fourth year (t = 4), the value is A = 73,205. So solve the system

[tex]\begin{cases}60,500=Pe^{2r}\\73,205=Pe^{4r}\end{cases}[/tex]

for r. You can eliminate P by dividing

[tex]\dfrac{Pe^{4r}}{Pe^{2r}}=\dfrac{73,205}{60,500}\implies e^{2r}=\dfrac{121}{100}[/tex]

Take the logarithm (log here means natural log) of both sides to get

2r = log(121/100)

r = 1/2 log(121/100)

r ≈ 0.0953

So the interest rate is about 9.53%.

10x + 12x + 9x + 10x + 10x + 5 - 9 + 9 + 14 + 133 + 136 = 900

add liket terms

22x + 29x + 19 + 269 = 900

51x + 288 = 900

subtract 288 from both sides

What is the common difference in the following arithmetic sequence? 2/3,1/6,-1/3,-5/6,...

A -4
B-1/2
C1/9
D4

Answers

Answer:

B.- [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

The common difference is the difference between the numbers in your arithmetic sequence. In this case, we see that the numbers are getting smaller, so we can start by setting up this equation:

[tex]\frac{2}{3} - \frac{1}{6}[/tex]

Because these fractions don't have a common denominator, you make them equal by changing the fractions to have a common denominator. The LCM is 6, so we multiply the first fraction by 2/2:

[tex]\frac{4}{6} - \frac{1}{6} = \frac{3}{6}[/tex]

3/6 can be simplified to be 1/2, and we know we're subtracting, so the answer is b.
