Rajib wrote the equations y = 8 x minus 2 and y = negative 4 x minus 5. What can Rajib conclude about the solution to this system of equations? The point (2, 14) is a solution to this system of equations. The point (14, 2) is a solution to this system of equations. The point (Negative 4, negative one-fourth) is a solution to this system of equations. The point (Negative one-fourth, negative 4) is a solution to this system of equations.

Answers

Answer:

The point (Negative 4, negative one-fourth) is a solution to this system of equations

Step-by-step explanation:

y = 8x - 2

y = - 4x - 5

y - 8x = - 2 - - (1)

y + 4x = - 5 - - - (2)

Subtract 1 and 2

-8x - 4x = - 2 - (-5)

-8x - 4x = 3

-12x = 3

x = - 1/4

y = 8(-1/4) - 2

y = - 2 - 2

y = - 4

(-1/4, - 4)

They need to make 70 baggies of cookies that each have 4 cookies in them. The recipe they are using says that one batch will make 2 dozen cookies.

Answers

Answer:

They need to make at least 12 batches.

Step-by-step explanation:

First, we need to find how many cookies in total, so we multiply 70 by 4.

70*4 = 280.

Secondly, 1 batch makes 2 dozen cookies, or technically 24 cookies. So we need to find how many batched with 280 divided by 24. This results in 11.6 repeating. But if you round it up, you get 12.

Time to check:

12 * 24 = 288. So it's the amount of cookies needed with 8 remaining.

What is wrong with this solution? -6t + 16 = -8 Step One: -6t + 16 = -8 - 16 Step Two: -6 • -6t = -24 • -6 Solution: t = 144

Answers

Answer:

t = 4

Step-by-step explanation:

In step two, instead of multiplying by -6 on both sides, you need to divide by -6 to isolate t.

-6t = -24

÷-6    ÷-6

t = 4

When you multiply by -6 on both sides, the equation would be 36t = 144, which is not what we want. The opposite of multiplication is division, and in order to get the answer, you divide by the number multiplied.

A.24 7/12 sq. inches
B. 24 7/12 cubic inches
C.175/6 sq. inches
D. 175/6 cubic inches

Answers

Answer:

Volume of rectangular prism = 175 / 6 inch³

Step-by-step explanation:

Given:

Base area of rectangular prism = 23 ¹/₃ inch² =  70 / 3 inch²

Height of rectangular prism = 1 ¹/₄ inch = 5 / 4 inch

Find:

Volume of rectangular prism

Computation:

Volume of rectangular prism = Base area of rectangular prism x Height of rectangular prism

Volume of rectangular prism = [70 / 3] x [5 / 4]

Volume of rectangular prism = [350 / 12]

Volume of rectangular prism = 175 / 6 inch³

General rules for shifting graphs:

Shift y = f(x) up by a units: y = f(x) + aShift y = f(x) down by a units: y = f(x) - aShift y = f(x) left by a units: y = f(x + a)Shift y = f(x) right by a units: y = f(x - a)
