-0.8b^2+7.4b+(5.6b-0.2b^2)

Answer: 25%

Step-by-step explanation:

From the question, we are told that a stuffy normally costs $12, but that this week it is on sale for $9.

The Percent of Change on the stuffy will be calculated as:

= Change / Normal cost × 100

= (12 -9) / 12 × 100

= 3/12 × 100

= 1/4 × 100

= 25%

Answer:

YES. (2, 7) is a solution of the system.

Step-by-step explanation:

System of linear inequalities has been given as,

y ≥ -x + 1 --------(1)

y < 4x + 2 ------(2)

If (2, 7) is a solution of the given system of inequalities, it will satisfy both the inequalities.

By substituting the coordinates of point (2, 7) in inequality (1),

7 ≥ -2 + 1

7 ≥ -1

True.

By substituting the coordinates of point (2, 7) in inequality (2),

7 < 4(2) + 1

7 < 9

True.

Therefore, point (2, 7) lie in the solution area of system of inequalities.

YES. (2, 7) is a solution of the system.

Answer: x = 3

Step-by-step explanation:

we subtract 2 from both sides, in order to get the variable by itself.

x + 2 (- 2) = 5 (- 2)

x = 3

Answer: The answer is 8

Step-by-step explanation: first you solve 16 to the 1.5 power (3/2=1.5) and that gives you 64. Then 64 to the .5 power (1/2=.5) and that gives you 8.

Answer:

70x

Step-by-step explanation:

8x8 = 64x then +6x = 70x

Answer:

[tex]2x(4x+3)[/tex]

Step-by-step explanation:

The first thing to factorising this expression is to find the greatest common factor (GCF). For 8x² and 6x the gcf is 2x. So now we divide the 8x² and 6x by the 2x. Which comes out to 4x and 3, these will be inside the parentheses.

So it'll factorise to [tex]2x(4x+3)[/tex] and remember when we are dividing with exponents we subtract the exponents. So [tex]\frac{8x^2}{2x}[/tex] we will divide the coefficients together that'll be 4 and now for the exponents the 2 on the x² minus the 1 on the x will equal 1 so it'll be just x we don't place a one or anything.

Answer:

A. 5cm, 6cm, 7cm

Step-by-step explanation:

Answer:

The correct option is;

A. It is a one-to-one function

Step-by-step explanation:

A function f(x), is a one to one function when each value in the range is given by each unique value in the domain such that each "x" value produces a unique "y" value.

The given graph has a domain of -2 ≤ x < ∞

Within the domain plotted in the graph, all lines with equation "x" = -2, -1, 0..., 4, 5 crosses the graph only once, therefore, for each value of "x", there is only one value of "y", which gives the relationship between the "x" and "y" values as one to one function

Answer:

B x = 7

Step-by-step explanation:

You know based on the ratio that it's being scaled by 4 times because the one side 4 is 16 in the bigger pentagon.

So if you go the side that matches the one you need to solve, it's 2.5.

2.5 times 4 = 10 so that bigger pentagon side should equal 10.

The equation x-3 = 10

which means x is 7

Answer:

A, D

Step-by-step explanation

A

2^2 = 4

4^2 = 16

D

2^2=4

2^4 = 16

Answer:

A and D

Step-by-step explanation:

A.) plug in 2 first then 4

2^2= 4 and 4^2= 16 so it applies

B.) does NOT apply bc 2+6=8 and not f(2)=4 and also does not equal to 16

4+6=10

C.) does NOT apply bc 4(2)+2=10 and not to 4 and also does not equal to 16; 4(4)+2=18

D.) does apply 2^2=4 and 2^4=16

Answer:

180

Step-by-step explanation:

If 40% = 72, 100% can be found like so:

40% = 72

100% =  [tex]\frac{100}{1}[/tex] * [tex]\frac{72}{40}[/tex]

You can reduce 40 and 100 by 20 (or probably more, but I'll use 20)

So now we have:

Divide, and you get 180.

To check, we can find 40% of 180.

(I looked it up)

Answer:

75

Step-by-step explanation:

because if you minus 155 and 80 then add 10 because its a trianagle s so you have to use the polymerson method so     you get 85

Answer:

360

Step-by-step explanation:

A quotient is the result of a division problem.

We must multiply -4 and -90.

-4 • -90 = 360

(There is no - because a negative multiplied by a negative equals a positive.)

Answer:

The slope is 2.

Step-by-step explanation:

You can take the second plotted point of the graph. (2,4)

Since slope is y/x, the equation is 4/2.

Answer: 192 in2

AL=(a+b+c)h=(10+8+6)·8=192

Answer:

$32

Step-by-step explanation:

First, find 20% of 40.

20% as a decimal is 0.20 (20/100)

0.20 x 40 = 8

Now, subtract 8 from the original price.

40 - 8 = 32

Answer:

$32

40 decrease 40%

40 x (1-20%) = 40 x (1-0.2) =32
