Answer:

Option A

Step-by-step explanation:

Bag A: 30 cents per bag

Bag B: 31 cents per bag

In order to find Cents per bag divide the number of bags from the amount it costs.

Bag A: 6 ÷ 20 = 0.30

Bag B: 9.92 ÷ 32 = 0.31

Answer:

B

Step-by-step explanation:

I say B cost the least per bag. I divided 32 by 9.92 and 20 by 6. That gives me the answers to what each bag costs. bag A costs 3.34 for each bag and bag B costs 3.22. So bag B is cheaper.

Answer: x = (-2,0) y = (0,-3) slope is -3/2

Step-by-step explanation: graph the line  by  using the slope and y intercept

The graph for the points (0, -3) and (2, -6) is plotted on the graph below.

The given equation is y-3= -3/2(x+4).

Graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them. The length of the lines and position of the points do not matter.

Graph the line using the slope and y-intercept, or two points.

Slope: -3/2

y-intercept: (0, -3)

Plot the points (0, -3) and (2, -6) on the graph

To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.

x-intercept(s): (−2,0)

y-intercept(s): (0,−3)

Therefore, the graph for the points (0, -3) and (2, -6) is plotted on the graph below.

Answer:

8.925 minutes or 0.14875 hours..?

Step-by-step explanation:

I feel like I'm missing something here... The 3.4 x 105 words seems off. Why didn't they just say 357 words?

Assuming that he types 40 WPM and they're looking for how long it would take for him to type 357 words:

[tex]3.4*105 = 357[/tex] words total

[tex]\frac{357}{40} = 8.925[/tex] minutes

Answer:

67/18 is 3.72 as a decimal.

Step-by-step explanation:

I know this because, to turn a fraction into a decimal, you must divide the numerator by the denominator.

67 ÷ 18 = 3.72

Therefore, 3.72 is my answer.

[tex]q = 6[/tex]

⇒ Step-by-step explanation:

Lets solve!

[tex]3q -5 = 13[/tex]

⇒ First we add 5 to both sides.

[tex]3q -5 = 13[/tex]

   [tex]+ 5[/tex]     [tex]+ 5[/tex]

    [tex]3q = 18[/tex]

⇒ Next we divide both sides by 3.

 [tex]\frac{3q}{3} = \frac{18}{3}[/tex]

[tex]q = 6[/tex]

⇒Woohoo! Brainliest Appreciated! Hope I helped!

Answer:

q = 6

Step-by-step explanation:

To solve for q, isolate the variable.

3q - 5 = 13

Move -5 to the right side and perform the inverse operation. Since you were subtracting on the left, add on the right.

3q = 13 + 5

3q = 18

The last step is to isolate the variable by dividing 3 by 18. The reason you divide on the right is because you were multiplying on the left, and you need to perform the inverse operation.

q = [tex]\frac{18}{3}[/tex]

q = 6

8x⁹⁶ is the simplified form of the expression.

Polynomial is made up of two terms, namely Poly (meaning “many”) and Nominal (meaning “terms.”). A polynomial is an expression composed of variables, constants, and exponents, combined using mathematical operations such as addition, subtraction, multiplication, and division (No division operation by a variable). Based on the number of terms present in the expression, it is classified as monomial, binomial, and trinomial. For example P(x) = x2-5x+11

Given here, the expression as (256x²⁵⁶)^³/₈

=(256)^³/₈ × (x²⁵⁶)^³/₈

=(2⁸)^³/₈ × (x³²)^³

=2³ × x⁹⁶

Hence, the answer is 8x⁹⁶

Answer:

The solution to these two equations is (3, 1)

Step-by-step explanation:

So for the elimination method, we are basically multiply each equation by a factor that would allow us to cancel them out..

We could rewrite the equations as the following to make the elimination method easier:

-2y + 3x = 7

y + 4x = 13

We could multiply the second equation by positive 2 in order to cancel out the y from the first equation when we add.

-2y + 3x = 7

2y + 8x = 26        --->  Now we have 11x = 33, when we simplify, we have x = 3.

Now to find our y value in order to find the solution, we would just plug in our x value and solve for y. **We can use either equation to find the answer for this...

-2y + 3x =7.

-2y + 3(3) = 7

-2y + 9 = 7

-2y = -2

y = 1.

We can double check our answer by plugging in both x and y values into the second equation.

4(3) + 1 = 13.

12 + 1 = 13, so we are correct.

The solution to these two equations is (3, 1)

Answer:

(f-g)(x) would be 2x-3

Answer:

y= 8x +7

Step-by-step explanation:

slope-intercept form:

y= mx +c, where m is the gradient (or slope) and c is the y-intercept.

Since it is a linear function, the gradient of any 2 points would be equal.

[tex]gradient = \frac{y1 - y2}{x1 - x2} [/tex]

Thus, gradient of the line

[tex] = \frac{39 - 23}{4 - 2} \\ = \frac{16}{2} \\ = 8[/tex]

Subst. m=8 into the equation:

y= 8x +c

To find the value of c, substitute a pair of coordinates.

When x=0, y= 7,

7= 8(0) +c

c= 7

Thus, the equation of the linear function is y= 8x +7.
