Ren was trying to solve a system of linear equations. He correctly argued that he could replace one equation by the sum of that

equation and a multiple of the other. H
produce a system that has the same solution as the original system.
To show this, Ren wrote down a system of equations. He then determined which other systems of equations would have the same solution as his original system. Rem
below.
-2x - 5y = -47
4x - 2y = -2
Complete the table below to determine which system(s) of equations has the same solution as the original system shown above. Choose Has the Same Solution or Do
for each system of equations.
Has the Same Solution Does Not Have the Same Solution
-14x + y = -41
4x - 2y = -2
-2x - 5y = -47
6x + 3y = 45
-2x - 5y = 47
8x - 5y = -8

Using a chart of values, graph the function f(x)=3^x
Citrus2011 [14]
Hey there!

For this problem, I would assume that you must make your own chart of values. You can do this by simply plugging in numbers like 1, 2, 3, etc... Since your graph won't be linear, you might want to do some negative numbers, as well. 

Also because your graph isn't linear, you might want to figure out or determine on your own just how far your curve will go. You can then figure out how many times you need to plug in an additional numbers for your function to then graph. 

I've attached a digital graph of this function, perhaps you can find it useful. 

Hope this helped you out! :-)

PLS HELP WILL MARK BRAINLIST IF ANSWER IS CORRECT !! :) FILL IN THE BLANKS
andrew-mc [135]

Answer:

Part 1) The volume of the storage body is 576 cubic feet

Part 2) To find out how many boxes can she fit in the storage body, divide the volume of the storage body by the volume of each box

Part 3) Sheila can fit 64 boxes into the truck

Step-by-step explanation:

step 1

Find the volume of the storage body

we know that

The volume of the of the storage body is equal to the volume of two rectangular prism

The volume of a rectangular prism is equal to

V=LWH

First rectangular prism (top)

V=(15)(6)(8-6)=180\ ft^3

Second rectangular prism (bottom)

V=(15-4)(6)(6)=396\ ft^3

The volume of the storage body is

V=180+396=576\ ft^3

step 2

we know that

To find out how many boxes can she fit in the storage body, divide the volume of the storage body by the volume of each box

step 3

substitute the given values

\frac{576}{9}= 64\ boxes

therefore

Sheila can fit 64 boxes into the truck

Howard is standing 87 yards from the bottom of a water reservoir. He estimates that the angle of elevation to the top of the wat
nekit [7.7K]
He is 174 yards from the top.

Since we have a 60° angle and a right angle, this is a 30-60-90 triangle.  In these triangles, we can label the sides as t, t√3 and 2t, with t being the side opposite the 30° angle (the smallest side); t√3 being the side opposite the 60° angle (the middle side); and 2t being the hypotenuse (the longest side).

Our 87 yard side is across from the 30° angle, so it is t.

The side we are looking for is the hypotenuse, which would be 2t; 2(87) = 174.
