Answer:

The rate of change is 0.75 gallons per minute

Step-by-step explanation:

The rate of change of the linear relation is represented by the slope of the line which represents this relation

The rule of the slope of a line is

m = Δy/Δx, where

From the given graph

∵ The line passes through points (0, 0) and (4, 3)

∴ Δx = 4 - 0 = 4

∴ Δy = 3 - 0 = 3

→ Use the rule of the slope above to find the slope of the line

∴ m = [tex]\frac{3}{4}[/tex] = 0.75

∵ The x-axis represents the time in minutes

∵ The y-axis represents the amount in gallons

∵ m represents the rate of change

∴ The rate of change = 0.75 gallons per minute

She will need  68 ounces in total for all three ingredients.

It is given that

For chocolate chips, she has  =  [tex]\dfrac{11}{4}[/tex] pounds

For walnuts, she has = [tex]\dfrac{3}{4}[/tex] pounds

For raisins, she has=  12 ounces

We know that,

[tex]\rm 1 \ pound = 16 \ ounces[/tex]

[tex]\rm For \ chocolate \ chips, she\ has = \dfrac{11}{4} \times 16 }=44 \ ounces[/tex]

[tex]\rm For \ walnuts,\ she\ has = \dfrac{3}{4} \times 16 }=12\ ounces[/tex]

[tex]\rm For\ raisins, she \ has= 12\ ounces[/tex]

so the total number of ounces she has will be the sum of all

[tex]=44+12+12 =68\ ounces[/tex]

Thus she will need  68 ounces in total for all three ingredients.

Answer:

x = 33°

explanation:

The interior angles sum up to 180°

solve:

x + 20° + 4x - 5° = 180°

x + 4x + 20° - 5° = 180°

5x + 15° = 180°

5x = 180° - 15°

5x = 165°

x = 33°

Answer:

x = 33

Step-by-step explanation:

Sum of consecutive interior angles = 180°

⇒ (x + 20) + (4x - 5) = 180

⇒ 5x + 15 = 180

⇒ 5x = 165

⇒ x = 33

Answer: The number of books she should put on each shelf = 7

Step-by-step explanation:

Given: Total books = 116

Total shelves = 16

To determine : The number of books she should put on each shelf, we first divides the total number of books by the total shelf.

[tex]116\div 16=7\dfrac14[/tex]

So she can put 7 books in each shelf such that (7x16=) 112 books got placed and (116-112=)4 books left.

Hence, The number of books she should put on each shelf = 7.

Answer: x= 4/3 but in decimal form =1.333

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    4-(2*(3*x-2))=0

4 -  2 • (3x - 2)  = 0

Pull out like factors :

  8 - 6x  =   -2 • (3x - 4)  

Solve  :    3x-4 = 0  

Add  4  to both sides of the equation :  

                     3x = 4

Divide both sides of the equation by 3:

                    x = 4/3 = 1.333

Answer:

x= undefined

Step-by-step explanation:

In order to make u understand , if u multiply 2(3x-2) it becomes 6x-4 which is the exact same as the left hand side . Therefore u cant find x from here in this manner .

For this however we can try the method bellow .

Lets say f(x)=y=6x-4=2(3x-2)

we can get the followig points for inserting domains and finind the domains . we can make graph for each . (We will not do them however)

As we have seen that both of those parts of the equation are one and the same so they will produce the exact same Line or curve .

Therefore every signle points on them r the same exact points and there fore they are the same exact line .

So the value of x is undefined and can be anything between every points on that line (Which can be infinit amounts of points) .

Answer:

f(-8) = 57

Step-by-step explanation:

When x = - 8

f(-8) = 2 x (-8)² + 7 x (-8) - 15

f(-8) = 2 x 64 - 56 - 15

f(-8) = 128 - 56 - 15

f(-8) = 128 - 71

f(-8) = 57

[tex]\sf f(x) = 2x^2 + 7x - 1[/tex]

Just substitute the value of x as (-8) .

[tex]\sf f(-8) = 2(-8)^2 + 7(-8) - 15[/tex]

[tex]\sf f(-8) = 2(64) - 7(8) - 15[/tex]

[tex]\sf f(-8) = 128 - 56 - 15[/tex]

[tex]\sf f(-8) = 128 - 71[/tex]

[tex]\sf f(-8) = 57[/tex]

Answer:

-2

Step-by-step explanation:

Open the brackets on both sides

12r + 16 = -16r - 40

collect like terms

12r + 16r = -40 - 16

28r = -56

r = -56/28

r = -2

The solution of the given equation [tex](4x-16)^{1/2} = 36[/tex] is 328.

The given equation is:

[tex](4x-16)^{1/2} = 36[/tex]

The solution of an equation is to find out the numeric value of the variable such that Left-hand side and Right-hand side becomes equal.

Squaring both sides of the given equation.

[tex][(4x-16)^{1/2} ]^2= (36)^2[/tex]

[tex]4x-16 = 36^{2}[/tex]

[tex]4x -16 =1296[/tex]

[tex]4x =1296+16[/tex]

[tex]4x = 1312[/tex]

x= 328

Therefore, The solution of the given equation [tex](4x-16)^{1/2} = 36[/tex] is 328.

The length of a rectangle is 5 more than twice the width. If the perimeter of the rectangle is 34 cm find the length?

In this question we are provided with the perimeter of the rectangle = 34 cm and it is given that the length of the rectangle is 5 more than the twice it's breadth and asked to find out the length of the rectangle.

[tex] \small \orange{ \underline{\rm \blue{length \: of \: a \: rectangle \: is \: 5 \: more \: than \: twice \: the \: width.}}}[/tex]

Let us assume breadth as x then length = 2x +5

We know,

[tex] \star \: \large\boxed{ \rm{ Perimeter_{(rectangle)} = 2(length + breadth)}}[/tex]

Substituting the values we get

34 = 2(2x +5 + x)

→ 34 = 2(3x + 5)

→ 34 = 6x + 10

→ 34 - 10 = 6x

→ 24 = 6x

→ [tex]\dfrac{24}{6}[/tex] = x

x = 4

Length = 2x + 5 = 2 × 4 + 5 = 8 + 5 = 13 cm

Breadth = x = 4cm

Length = 13 cm.
