(9r - 5 ) - ( -4r + 9 ) Can you subtract the expression

Answer:

(-4,22)

Step-by-step explanation:

Answer:

(- 4, 22 )

Step-by-step explanation:

To determine which point lies on the graph, substitute the x- coordinate of the point into the equation and if the value obtained is equal to the y- coordinate of the point then it lies on the graph.

(1, - 2 )

y = - 4(1) + 6 = - 4 + 6 = 2 ≠ - 2 ← not on graph

(- 4, - 10 )

y = - 4(- 4) + 6 = 16 + 6 = 22 ≠ - 10 ← not on graph

(- 4, 22 )

y = - 4(- 4) + 6 = 16 + 6 = 22 ← lies on graph

(1, - 10 )

y = - 4(1) + 6 = - 4 + 6 = 2 ≠ - 10 ← not on graph

Answer:

[tex]y=\frac{5}{4}x+7[/tex]

Step-by-step explanation:

We can start by setting up what we know of the slope-intercept equation, which is the slope.

[tex]y=\frac{5}{4}x+b[/tex]

Now, we can use the given point to find the y-intercept.

[tex]2=\frac{5}{4}(-4)+b\\ 2=-5+b\\b=7[/tex]

And now we are able to write the slope-intercept equation.

[tex]y=\frac{5}{4}x+7[/tex]

I hope this helps!

Answer:

[tex]V= 2x^3[/tex]

The volume is 128cm^3

Step-by-step explanation:

Given

[tex]Cubes = 2[/tex]

[tex]Sides = 4cm[/tex]

Required

Determine an expression for its volume

Find the volume

Volume of a cube is:

[tex]Volume = x^3[/tex]

Where x represents the length of a side

So, volume of 2 cubes would be:

[tex]V= x^3 + x^3[/tex]

[tex]V= 2x^3[/tex]

Solving (b): Volume when x = 4

Substitute 3 for x in [tex]V= 2x^3[/tex]

[tex]V = 2 * 4^3[/tex]

[tex]V = 2 * 64[/tex]

[tex]V = 128[/tex]

Hence, the volume is 128cm^3

Answer:

1. y-4=2(x-2) 2.y-4=1/3(x- -4)

Step-by-step explanation:

Point slope form can be written as y-y1=m(x-x1)

(x1,y1) represents the coordinates provided

m= the slope, which is also provided in the question

Simply fill in the provided numbers into the point slope form equation

hope this helps and take care

Answer: I found the perimeter of the rectangle I got: 10x+4

Step-by-step explanation:

Answer:

13 units

Step-by-step explanation:

It is an equilateral triangle, so all sides have the same length

so you're going to need to find the slope. in order to do that use (y2-y1)/(x2-x1)

(7-(-2))/(0-8)

simplify

9/-8

simplify -9/8

now using y=mx+b, we need to find b. so we can plug in the coordinates of (0,7) or (8,-2). let's use (8,-2) because it involves more math.

y=mx+b

-2=(-9/8)(8)+b

multiply (-9/8) by 8 to get -9

-2=-9+b

add 9 to both sides

7=b

so our equation is now

y=-(9/8)x+7

Step-by-step explanation:

sqrt(i^2*16*3) = 4i[tex]\sqrt{3\\}[/tex]

sqrt(i^2*9*7) = 3i[tex]\sqrt{7}[/tex]

sqrt(i^2*36*2) = 6i[tex]\sqrt{2}[/tex]

sqrt(i^2*6*4) = 2i[tex]\sqrt{6}[/tex]

sqrt(i^2*4*3*7) = 2i[tex]\sqrt{21}[/tex]

sqrt(i^2*9*11)= 3i[tex]\sqrt{11}[/tex]

Answer:

32 gallons

Step-by-step explanation:

A standard showerhead in Marty's house dispenses 7 gallons of water per minute. If he showers for 8 minutes, he uses:

1 minute = 7 gallons

8 minutes = x

x = 7 × 8 minutes = 56 gallons of water

We are told that:

Marty changed this showerhead to an energy-saving one. The equation shows the amount of water dispensed, y, as a function of the number of minutes, x, for the new showerhead. y = 3x

The equation for the energy saving shower:

y = 3x

Where x is the number of minutes spent in the shower

For 8 minutes

y = 3 × 8

y = 24 gallons

The gallons of water Marty saved each day with the change in showerheads if he uses the shower for 8 minutes each day is calculated as:

56 gallons - 24 gallons

= 32 gallons
