Answer:

3

Step-by-step explanation:

Note that adding a negative quantity is equivalent to subtracting the negative quantity, that is

7 + (- 4) = 7 - 4 = 3

Answer:

[tex]f(a) = 4(a + 4) - 3 = 4a + 16 - 3 \\ f(x) = 4a + 13 \\ f(5) = 4(5) + 13 = 20 + 13 \\ \boxed{f(5) = 33}[/tex]

Answer:

slope is 1/3

Step-by-step explanation:

In between the points, you go up one, and forward 3. it can't be a negative slope cause it aint going down. And the slope of 3 is steep last time I checked.

Answer:

m=1/3

Step-by-step explanation:

you can do rise over run or y2-y1/x2-x1 with two coordinate points

Answer:

C. Mario should have multiplied the x-values by $6.50 to get the y values.

Step-by-step explanation:

Let's do it the way they said. If we were to multiply 1 by 65, it would be $65. If we did the same thing for 2, 2 x 65 is $130. This is incorrect because these values do not match up with the ones on the graph.

Decimal points are important in this case because it completely changes your answer. When you multiply 1 by 6.50, you get 6.50. Which is what's on the graph. Multiply 2 by 6.50 and you'll get $13, and so on.

So now we can conclude that the mistake Mario made was that he multiplied x by the wrong value (65), when it should have been $6.50.

Note: Hope this helps! Good luck on your test. :)

Answer:

Factoring the term [tex](5x^5) - (80x^3)[/tex] we get [tex]\mathbf{5x^3(x-4)(x+4)}[/tex]

Step-by-step explanation:

We need to factor the term [tex](5x^5) - (80x^3)[/tex]

First we can see that [tex]5x^3[/tex] is common in both terms

So, taking [tex]5x^3[/tex] common:

[tex](5x^5) - (80x^3)\\=5x^3(x^2-16)[/tex]

We can write [tex]x^2-16[/tex] as [tex](x)^2-(4)^2[/tex]

[tex]=5x^3((x)^2-(4)^2)[/tex]

Now we can solve [tex](x)^2-(4)^2[/tex] using the formula: [tex]a^2-b^2=(a+b)(a-b)[/tex]

We can write:

[tex]=5x^3((x)^2-(4)^2)\\=5x^3(x-4)(x+4)[/tex]

So, factoring the term [tex](5x^5) - (80x^3)[/tex] we get [tex]\mathbf{5x^3(x-4)(x+4)}[/tex]

Step-by-step explanation:

Answer:

Shape 1: 197.04

Shape 2: 125.44

Shape 3: 62.72

Step-by-step explanation:

For shape 1, you first need to find the radius to then find the area of a circle. Which is 394.08. Since this isn't a full circle, you will need to divide it by 2 to get 197.04. For shape 2(Easiest to find) You do 11.2*11.2 to get the answer of 125.44. And lastly for shape 3, you can basically do the same as what you did for shape 2. But since it is a triangle, you divide your answer by 2, to get the answer of 62.72.

Answer:

30%

Step-by-step explanation:

Answer:

15%

Step-by-step explanation:

To determine the percentage of the girls with blonde hair...it means we will have to use this formula

Number of girls with blonde hair/total numbers of girls ×100

Number of girls with blonde hair is 12

Total number of girls is 80

Therefore,12/80 ×100

1200/80

120/8

15

Therefore the percentage of the girls with blonde hair is 15%

Answer:

x=-3.14

or -3 with -.5 remainder

Step-by-step explanation:

PEMDAS

Parenthesis Exponent Multiply Divide Add Subtract

parenthesis  3.5*x=3.5x 3.5*2=7

3.5x+7=-4

subtract 7 from both sides

3.5x=-11

divide both sides by 3.5

x=-3.14

or -3 with -.5 remainder

Answer:

x=-22/7

Step-by-step explanation:

multiply 3.5 and x then multiply 3.5 and 2. this will get you 3.5x+7=-4. next you need to subtract the 7 from the -4, resulting in 3.5=-11. finally divide -11 and 3.5, after that you get the answer of x=-22/7 or -3 1/7. if you need decimal form that will be -3.142857

Answer:

Option (4)

Step-by-step explanation:

x              g(x)            Ist difference          IInd difference        Ratio

1              13                      -                                   -                        -

2              3                3 - 13 = -10                         -                       [tex]\frac{3}{13}[/tex]  

3             -3               -3 - 3 = -6                   -6 - (-10) = 4            [tex]\frac{-3}{3}=-1[/tex]

4             -5               -5 - (-3) = -2                -2 - (-6) = 4             [tex]\frac{-5}{-3}=\frac{5}{3}[/tex]

5             -3               -3 - (-5) = 2                   2 - (-2) = 4            [tex]\frac{-3}{-5}=\frac{3}{5}[/tex]

This table depicts,

1). Ist difference is not common

2). IInd difference is common

3). Ratio is not common

Therefore, this table represents a quadratic function because the second difference are all the same value.

Option (4) will be the answer.

Answer:

3/50

Step-by-step explanation:

Well according to the information we have the fraction would be

6/100 being 6% as 6/100

Then simplified is 3/50

Answer:

Step-by-step explanation:

6% = [tex]\frac{6}{100}[/tex]=[tex]\frac{3}{50}[/tex]

Answer:

1,620,000 meters

Step-by-step explanation:

Speed-   450 meter----- 1 second

1 minute = 60 seconds

60 minutes (1 hour) = 3600 seconds

Distance in 1 hour

1 ------ 450

3600---- X

X= 3600 x 450

x= 1,620,000 meters

Step-by-step explanation:

8 Times Table

8 × 1 = 8

8 × 2 = 16

8 × 3 = 24

8 × 4 = 32

8 × 5 = 40

8 × 6 = 48

8 × 7 = 56

8 × 8 = 64

8 × 11 = 88

8 × 12 = 96

Answer:

10/27 cups

Step-by-step explanation:

y = how much flour is needed

set up proportion of water to flour equals water to flour

[tex]\frac{3/5}{2/3}[/tex] = [tex]\frac{1/3}{y}[/tex]

cross-multiply:  3/5 y = 2/9

multiply each side by the reciprocal of 3/5

5/3 · (3/5)y = 2/9 · (5/3)

y = 10/27

Answer: 10/27 cups flour.

Step-by-step explanation:

Compare fractions 3/5 and 1/3:

[tex]\dfrac{3}{5}=\dfrac{3 \times 3}{5 \times 3} =\dfrac{9}{15} \\\\ \dfrac{1}{3}=\dfrac{1 \times 5}{3 \times 5} =\dfrac{3}{15}\\\\\dfrac{3}{15} < \dfrac{9}{15}[/tex]

1/3 is less than 3/5 because 3/15 is less than 9/15.

Find how many times 1/3 is less than 3/5:

[tex]\dfrac{3}{5} \div \dfrac{1}{3} =\dfrac{3}{5} \times \dfrac{3}{1}=\dfrac{9}{5}[/tex]

This means that flour should also be taken 9/5 times less:

[tex]\dfrac{2}{3} \div \dfrac{9}{5} =\dfrac{2}{3} \times \dfrac{5}{9} =\dfrac{10}{27}[/tex]
