Answer:

y = -x +4

Step-by-step explanation:

The y-intercept of the line is at +4, so the only viable choice is the last choice.

___

Each of the equations is shown in slope-intercept form:

y = mx + b

where b is the y-intercept, the y-value when x=0. The graph shows that as point (0, 4). So, the equation you're looking for is ...

y = (some x-term) +4

If you want to spend more brain power on the problem, you can compute the slope of the line as ...

m = ∆y/∆x = (1-4)/(3-0) = -3/3 = -1

Now, you know for sure the equation of the line is ...

y = -x +4

A number y is 5 times the value of a number x. A line graphed in a coordinate plane represents the relationship between x and y.

VLD [36.1K]

Answer:

Step-by-step explanation:

If we know that y is 5 times x then we can say for everytime x goes up 1, y goes up 5.

Which comes to the slope of 5/1 which can be simplified to just 5.

each cube inside the rectangular prism has an edge length 3/4 inch.What is the volume of the rectangular prism?

NNADVOKAT [17]

Answer:

$\frac{27}{64}n\,\,cubic\,\, inches$

Step-by-step explanation:

Given: Edge length of cube = $\frac{3}{4}\,\,inch$

To find: Volume of the rectangular prism

Solution:

A cube is a three-dimensional solid object which has 12 edges, 8 vertices and 6 faces.

A rectangular prism is a solid three-dimensional object which has six faces that are rectangles.

Let n denotes number of cubes inside the rectangular prism

Volume of one cube = $(edge)^3=(\frac{3}{4})^3 =\frac{27}{64}$ cubic inches

So, volume of rectangular prism = volume of n cubes = $\frac{27}{64}n\,\,cubic\,\, inches$

Ada, Betty, Chris, and David have $45 in total. If Ada gets $2 from Betty, Chris triples his money, and David's money is cut by

masya89 [10]

The amount of money Ada have initially is $9.25 and this can be determined by forming the linear equation.

Given :

Ada, Betty, Chris, and David have $45 in total.
If Ada gets $2 from Betty, Chris triples his money, and David's money is cut by half, four of them have the same amount.

The following steps can be used in order to determine the money Ada have initially:

Step 1 - Let the total money of Ada be 'a', Betty be 'b', Chris be 'c', and David be 'd'.

Step 2 - The linear equation that represents the total money they have is given by:

a + b + c + d + = 45 -- (1)

Step 3 - Now, after Ada gets $2 from Betty, Chris triples his money, and David's money is cut by half, four of them have the same amount of money.

Step 4 - Let the amount of money they all have be 'x' then:

4x = 45 ---- (from equation (1))

x = $11.25

Step 5 - The initial amount of money Ada have is:

x = a + 2

11.25 = a + 2

11.25 - 2 = a

a = $9.25

So, Ada have $9.25 initially.
