Which of the coordinate pairs is a point on the line y = -2/5x + 4?

A.) (2, 3)
B.) (-5, 6)
C.) (6, 2)
D.) (-2/5, 4)​

Answers

Answer:

B.) (-5, 6)

Step-by-step explanation:

to solve algebraically, test the coordinate pairs in the equation [tex]y = -\frac{2}{5}x + 4[/tex]

to solve graphically, enter the equation [tex]y = -\frac{2}{5}x + 4[/tex] into a graphing calculator and graph the coordinate pairs as well to see which one is on the line.

(2, 3) is NOT a solution.

steps for solving algebraically:

first, identify the x and y values in your coordinate pair.

2 is the x-value and 3 is the y-value. coordinate pairs are always written as (x, y).

plug in 2 for x in [tex]y = -\frac{2}{5}x + 4[/tex] (it doesn't matter if you plug in x or y first, i personally always start with the x-value but it really doesn't matter what order you do it in.)

y = -2/5x + 4 ⇒ y = -2/5(2) + 4

now plug in 3 for y.

y = -2/5(2) + 4 ⇒ 3 = -2/5(2) + 4

your equation is now 3 = -2/5(2) + 4. begin simplifying by multiplying -2/5 and 2.

3 = -2/5(2) + 4 ⇒ 3 = -0.8 + 4 (i converted my answer to a decimal because i'm better at dealing with decimals as opposed to fractions lol)

now add -0.8 + 4 to simplify the rest of the right side of the equation.

3 = -0.8 + 4 ⇒ 3 = 3.2

3 and 3.2 are not equal, therefore (2, 3) is not a solution.

(-5, 6) IS a solution.

steps for solving algebraically:

first, identify the x and y values in your coordinate pair.

-5 is the x-value and 6 is the y-value. coordinate pairs are always written as (x, y).

plug in -5 for x in [tex]y = -\frac{2}{5}x + 4[/tex] (it doesn't matter if you plug in x or y first, i personally always start with the x-value but it really doesn't matter what order you do it in.)

y = -2/5x + 4 ⇒ y = -2/5(-5) + 4

now plug in 6 for y.

y = -2/5(-5) + 4 ⇒ 6 = -2/5(-5) + 4

your equation is now 6 = -2/5(-5) + 4. begin simplifying by multiplying -2/5 and -5.

6 = -2/5(-5) + 4 ⇒ 6 = 2 + 4

now add 2 + 4 to simplify the rest of the right side of the equation.

6 = 2 + 4 ⇒ 6 = 6

6 and 6 are equal, therefore (-5, 6) is a solution.

although we have identified (-5, 6) as a solution, i'm still going to check the rest of the points just to be sure! :)

(6, 2) is NOT a solution.

steps for solving algebraically:

first, identify the x and y values in your coordinate pair.

6 is the x-value and 2 is the y-value. coordinate pairs are always written as (x, y).

plug in 6 for x in [tex]y = -\frac{2}{5}x + 4[/tex] (it doesn't matter if you plug in x or y first, i personally always start with the x-value but it really doesn't matter what order you do it in.)

y = -2/5x + 4 ⇒ y = -2/5(6) + 4

now plug in 2 for y.

y = -2/5(2) + 4 ⇒ 2 = -2/5(2) + 4

your equation is now 2 = -2/5(6) + 4. begin simplifying by multiplying -2/5 and 6.

2 = -2/5(6) + 4 ⇒ 2 = -2.4 + 4 (i converted my answer to a decimal because i'm better at dealing with decimals as opposed to fractions lol)

now add -2.4 + 4 to simplify the rest of the right side of the equation.

2 = -2.4 + 4 ⇒ 2 = 1.6

2 and 1.6 are not equal, therefore (6, 2) is not a solution.

(-2/5, 4) is NOT a solution.

i see that they want to trick you with this one by using the values that are in other spots in the equation... that's crafty

steps for solving algebraically:

first, identify the x and y values in your coordinate pair.

-2/5 is the x-value and 4 is the y-value. coordinate pairs are always written as (x, y).

plug in -2/5 for x in [tex]y = -\frac{2}{5}x + 4[/tex] (it doesn't matter if you plug in x or y first, i personally always start with the x-value but it really doesn't matter what order you do it in.)

y = -2/5x + 4 ⇒ y = -2/5(-2/5) + 4

now plug in 4 for y.

y = -2/5(-2/5) + 4 ⇒ 4 = -2/5(-2/5) + 4

your equation is now 4 = -2/5(-2/5) + 4. begin simplifying by multiplying -2/5 and -2/5.

4 = -2/5(-2/5) + 4 ⇒ 4 = 0.16 + 4 (i converted my answer to a decimal because i'm better at dealing with decimals as opposed to fractions lol)

now add 0.16 + 4 to simplify the rest of the right side of the equation.

4 = 0.16 + 4 ⇒ 4 = 4.16

4 and 4.16 are not equal, therefore (-2/5, 4) is not a solution.

as for finding the solution on a graph, enter the equation for the line as well as the coordinate pairs into a graphing calculator. here i used a handy little site called desmos in order to graph all of this. the first photo i attached contains what i entered into the calculator, and the second photo i attached shows the graph. as you can see, the only point that is actually on the line is (-5, 6), which is why (-5, 6) is a solution to [tex]y = -\frac{2}{5}x + 4[/tex] , and the other coordinate pairs are not solutions to that equation because they are not on the line.

No, I don't think so.

I don't think this is a function because the triangle is made of multiple points. Some of these points share the same x point, so this concludes that a triangle on a graph is not a function.

Jocelyn was given a box of assorted chocolates for her birthday. Each night, Jocelyn treats herself to some chocolates. The number of chocolates remaining in the box tt days after Jocelyn's birthday can be modeled by the equation C= -3t+30. What is the x-intercept of the equation and what is its interpretation in the context of the problem?

Answers

9514 1404 393

Answer:

"x-intercept": t = 10the chocolates will be gone after 10 nights

Step-by-step explanation:

The "x-intercept" is the value of the independent variable (t, in this case) such that the value of the dependent variable (C) is zero. We can find it by solving the equation ...

  0 = C

  0 = -3t +30

  0 = -t +10  . . . . .  divide by 3

  t = 10 . . . . . . . . . add t

The value of t is the number of days Jocelyn has been eating the chocolates. When t=10, C =0. The number of chocolates remaining in the box will be zero after 10 days.

Answer:

The x-intercept of the function is 10 which represents the number days after Jocelyn's birthday until all of the chocolates are gone.

Step-by-step explanation:

Since there were 0 chocolates remaining after 10 days, the x-intercept of 10 represents the number of days until the box of chocolates was empty.

Have a good day :)

Answers

When you divide you get 6.666667 then in fraction it is 20/3 so in mix number 6 2/3.
either use a calculator or convert into improper fractions

7 1/2=15/2
1 1/8=9/8

so now do 15/2 divided by 9/8

turn 9/8 into reciprocal
its gonna be 8/9
then multiply

15/2 times 8/9

15*8=120
2*9=18

120/18 is your answer but simplify it or else teachers will be annoying

simplify it by 6 cause its the gcf (greatest common factor)
