-3x + 2y = 56
-5x - 2y= 24

Answers

Answer 1

Answer:

x = -10 and y = 33

Step-by-step explanation:

just plug them in for x and y, you'll see that they're correct

Answer 2

Answer:

(- 10, 13 )

Step-by-step explanation:

Given the 2 equations

- 3x + 2y = 56 → (1)

- 5x - 2y = 24 → (2)

Adding the 2 equations term by term eliminates the y- term, that is

- 8x = 80 ( divide both sides by - 8 )

x = - 10

Substitute x = - 10 into either of the 2 equations and solve for y

Substituting into (1)

- 3(- 10) + 2y = 56

30 + 2y = 56 ( subtract 30 from both sides )

2y = 26 ( divide both sides by 2 )

y = 13

Solution is (- 10, 13 )

Find the slope of the line y=1/6x+3/2

Answers

y = mx + b

The coefficient of x is the slope.

So the slope is 1/6. m = 1/6

The slope of the given line is  [tex]\frac{1}{6}[/tex].

The slope of a line is the ratio of the amount that y increases as x increases some amount. Slope tells you how steep a line is, or how much y increases as x increases.

When a linear equation is written in slope intercept form, the slope of the line can easily be identified. The slope is "m" or the coefficient of x in the equation.

According to the question ;

The given line is

[tex]y = \frac{1}{6} x + \frac{3}{2}[/tex]

By comparing with the standard equation of the line .

y = mx + c

[tex]m = \frac{1}{6} \\ c = 6 \\[/tex]

Now ; slope of the line = m =   [tex]\frac{1}{6}[/tex]

The slope of the line is  [tex]\frac{1}{6}[/tex] .

1. For every 1/4 mi Pascal walks, Lucien runs 2/3 mi. How many miles does Pascal walk for every 1 mi Lucien runs? Write your answers in the blanks. Write a complete sentence to answer the question.​

Answers

Answer:

Step-by-step explanation:

1/4:2/3 = x:3/3

cross multiply

1/4         x

2/3       1

2/3x=1/4

divide by 2/3 on both sides..

when you divide a fraction you multiply by its reciprocal

Jessica earns 800 each month working a part time job. she wants to save a total of 2,400 for collage over a one- year period. what percentage of Jessica's total monthly budget should go to her collage savings to meet her goal

Answers

Answer:

25%

Step-by-step explanation:

Given parameters:

Amount earned by Jessica per month = 800

Total savings target per year  = 2400

Unknown:

Percentage of savings = ?

Solution:

The total earning per year will be the amount earned per month multiplied by the total number months;

 Amount earned in a year = 12 x 800  = 9600

Let the percentage of savings per year  = y%

  Now;

              2400 = [tex]\frac{y}{100}[/tex] x 9600

                  y = 25%

Describe the slope of the line.

Answers

the slope of the line is positive.
the slope is 4/3.

it’s positive because the line is rising/going up
the slope is 4/3 because it rises 4 units and goes to the left 3 units.

The slope of line from the given graph is 4/3.

The coordinates of line from the given graph are (4, 3) and (1, -1).

What is slope of a line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

Now, put (x1, y1) = (4, 3) and (x2, y2) = (1, -1) is slope formula, we get

Slope = (y2-y1)(x2-x1)

= (-1-3)/(1-4)

= 4/3

Therefore, the slope of line from the given graph is 4/3.

Is 7,8,10 linear or non linear and why and pls don’t use big words cuz I don’t and then the teacher gonna ask why hahahah

Answers

Answer:

9 and 8 are linear and 10 is non linear

Step-by-step explanation:

an = dn - c

The an stands for the nth term of the pattern. So a1 is the first term and a2 is the second term of the pattern. The d is the difference between each of the terms. The n stands for the term you're calculating. If you're calculating the third term, then n is 3. And c is a constant that you'll need to calculate.

For example, the linear number pattern of 1, 3, 5, 7, 9, … has an equation of:

an = 2n - 1.
