Answer:

y=-1/4x +3

Step-by-step explanation:

See the attached above.

Hope it helps :-)

Answer: for the first one it’s y= -6/5x -4

for the second one it’s y=1/5x-2

for the 3rd one it’s y=1/4

for the 4th one it’s y=-x+1/2

Step-by-step explanation:

1)

[tex]y = - \frac{6}{5} x - 4[/tex]

2)

[tex]y = \frac{1}{5} x - 2[/tex]

3)

[tex]y = \frac{1}{4} x[/tex]

4)

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

[tex] \sqrt{48} + \sqrt{108} \: \: in \: \: \: form \: \: of \: \: k \sqrt{6} \\ \sqrt{48} + \sqrt{108} = \sqrt{(4 \times 4 \times 3)} + \sqrt{(9 \times 3 \times 4)} = \\ 4 \sqrt{3} + 6 \sqrt{3} = 10 \sqrt{3} [/tex]

Answer:

  y = 1/2x - 4

Step-by-step explanation:

y = mx + b

-3 = 1/2(2) + b

-3 = 1 + b

b = -4

y = 1/2x - 4

Answer:

7.50 x 3= 22.50

22.50+9= 31.50

Step-by-step explanation:

If each necklace was $7.50 and she got one for each of her 3 sisters then we need to multiply $7.50 by 3. Finally, she has $9 left over. So if we add the total she spent on the necklaces and the 9 she has left over then we will get the total she started with.

Answer:

a = 0

Step-by-step explanation:

a + 5 = −5a + 5

subtract the 5a and bring it to the left and take the 5 on the left and bring it to the right then solve.

6a = 0

divide and you get

a = 0

Answer:

5

Step-by-step explanation:

Did you mean length instead of tenth? If so, 22*2=44, 64-44=20, 20/2=10. The length of the rectangle is 10 so to find the value of x, divide 10 by 2 so, 10/2=5, and x is equal to 5. : )

1. The total amount of candy is 1,080 pieces of candy.

2. Each student would get 72 pieces of candy.

Answer:

each student will get 5 pieces of candy

Step-by-step explanation:

20+15+25+12 =72

72 divided by 15 = 5

13. You are correct. You multiply the outer 5 with each term inside, and add.

-----------

14. The number 0 goes in the first blank and 8 goes in the second blank. So we have 8+0 = 8. The identity property of addition says that adding 0 to any number leads to the same result. In terms of algebra, x+0 = x.

-----------

15. The fraction 1/8 goes in the first blank and 1 goes in the second blank. We have the equation 8(1/8) = 1. Multiplying any nonnegative number x with its reciprocal 1/x leads to 1.

----------

16. The number 1 goes in the first blank and -4 goes in the next blank. This property is similar to the property mentioned in problem 14. This time we're working with the multiplicative version. We have the equation -4*(1) = -4

----------

17. The letter a goes in the first blank and x+3 goes in the second blank. So the last equation is a = x+3. The transitive property is the idea of us chaining equations together. It's like saying "if A goes to B, and B goes to C, then A goes to C". Think of it like taking a shortcut bypassing B entirely.

Step-by-step explanation:

Answer:

y = 3

Step-by-step explanation:

Slope = 0/-6 = 0

y-int. = 3

The linear function [tex]f[/tex] with [tex]f(0) = 3[/tex] and [tex]f(-6) = 3[/tex] is [tex]y = 3[/tex].

Given two distinct points on cartesian plane, we can determine the linear function associated to those points as follows:

[tex]y = m\cdot x + b[/tex] (1)

[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] (2)

[tex]b = y_{1}-m\cdot x_{1}[/tex] (3)

If we know that [tex]f(0) = 3[/tex] and [tex]f(-6) = 3[/tex], then we have the linear function below:

[tex]m = \frac{3-3}{0-(-6)}[/tex]

[tex]m = 0[/tex]

[tex]b = 3 - 0\cdot (0)[/tex]

[tex]b = 3[/tex]

The linear function [tex]f[/tex] with [tex]f(0) = 3[/tex] and [tex]f(-6) = 3[/tex] is [tex]y = 3[/tex].
