3. Francis has an unpaid balance of $480 on his credit card.
The annual percentage rate is 12%. What is the finance
charge on his next monthly statement?

Answer:

b=16

Step-by-step explanation:

1) Divide 3 on both sides.

2) 3 divided by 3 and 48 divided 3.

3) Now you're left with 16, so the value of b is 16.

Answer:

1) Divide both sides by 3

2) b=16

Step-by-step explanation:

To solve the equation, we want to find out what b is. In order to do this, we have to get b by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.

3b=48

3 and b are being multiplied (3b=3*b). The opposite of multiplication is division. Therefore, divide both sides by 3.

3b/3=48/3

The 3s on the left will cancel, and we are left with:

b=48/3

b=16

hey question do you still need help answering this cuz I noticed you posted this a while ago so I'm not sure.....let me know!

Answer:

Option A

Step-by-step explanation:

If a football team gains 15 yards on a play, it will be recorded as '+ 15' or '15'.

All other options would be represented by '-15', and not '15' that is asked in the question. A withdraw is taking away money, a number 'below zero' would be negative, and losing 15 points would be represented as '-15'.

Option A should be the correct answer.

Answer:

The answer to your problem is Option A or 1: A football team gains 15 yards on a play.

Step-by-step explanation:

This is the answer because all of the other situations have an integer of -15. Like LOSING points, or 15 meters BELOW all signify that those situations include a negative number. Your question is asking for a positive 15 not negative so Option 1 is the correct answer.

Answer:

c

Step-by-step explanation:

(4 + 6i)(7-2i)=

28-8i+42i-12i^2

i^2=-1, so

28+12-8i+42i

40+34i

answer is c

Answer:

We have axis of symmetry in [tex]x=-1[/tex]

The vertex point is [tex](-1, -9)[/tex]

The roots by factoring are

[tex]x=-4[/tex]

[tex]x=2[/tex]

Step-by-step explanation:

We have the function:

[tex]f(x)=x^2+2x-8[/tex]

Factoring the quadratic equation:

[tex]y=(x+4)(x-2)[/tex]

When [tex]y=0[/tex]

[tex]0=(x+4)(x-2)[/tex]

[tex]x=-4[/tex]

[tex]x=2[/tex]

The vertex point is [tex](h, k)[/tex]

From the equation, we have [tex]a=1,\:b=2 \text{ and }\:c=-8[/tex]

[tex]$h=-\frac{b}{2a}$[/tex]

[tex]$h=-\frac{2}{2\cdot \:1}$[/tex]

[tex]h=-1[/tex]

We also got the axis of symmetry

In order to find [tex]k[/tex] just use the [tex]$h=x_{vetex}$[/tex]:

[tex]k=(-1)^2+2(-1)-8\\k=1-2-8\\k=-9[/tex]

Once [tex]a>0[/tex], we have the minimum at [tex](-1, -9)[/tex]

Answer:

x = -1  axis of symmetry

(-1,-9) vertex

x = -4           x=2   are the roots

Step-by-step explanation:

y = x^2 + 2x - 8

The axis of symmetry is

h = -b/2a

h = -2/ (2*1) = -2/2 =-1

x = -1

The x coordinate of the vertex is at the axis of symmetry

To find the y value substitute into the function

y = (-1)^2 +2(-1) -8

y = 1-2-8

y = -9

The vertex is at ( -1,-9)

Factor

What 2 number multiply to -8 and add to 2

4*-2 = -8

4+-2 = 2

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

Using the zero product property to find the roots

0 = ( x+4) (x-2)

x+4 =0    x-2 =0

x = -4           x=2   are the roots

Answer:

You will pay $18 for a item with original price of $90 when discounted 80%. In this example, if you buy an item at $90 with 80% discount, you will pay 90 - 72 = 18 dollars.

Step-by-step explanation:

Answer:

Original Price is $450

Step-by-step explanation:

(Discounted price) = (100 percent - discount percent) x (original price)

90 = (100%- 80%) x y

y = 90 / 0.20

= 450

r Radius

19

cm

Solution

A=πr2=π·192≈1134.11495cm²

Answer: 1133.54

Step-by-step explanation:

The formula of area of a circle: A = [tex]\pi[/tex]r squared

All you have to do is plug the numbers in, so A= 3.14 (19) squared. Solve

19 times 19 = 361, and 3.14 times 361 = 1133.54

Step-by-step explanation:

Answer:

Cost, C = $28410.72

Step-by-step explanation:

We have, a concrete pillar has the shape of a cylinder.

Diameter of pillar is 8 m and ts height is 9 m

If concrete costs $87 per cubic meter, it is required to find the concrete cost for the pillar. For this lets find the area of cylindrical shape. So,

[tex]A=2\pi rh+2\pi r^2\\\\A=2\times 3.14\times 4\times 9+2\times 3.14\times 4^2\\\\A=326.56\ m^2[/tex]

The cost of pillar at the rate of $87 per cubic meter will be :

[tex]C=326.56\times 87\\\\C=\$28410.72[/tex]

Answer:

Question 7: Distributive

You multiple the outside element by each element inside the parenthesis

Question 5: 1.2x + 12.3y

2.4(3x + 2y) - 1.5(4x - 5y)  = 7.2x + 4.8y - 6x + 7.5y  = 1.2x + 12.3y

Question 3: 1 (3/5)x - (3/10)y

(2/5)(4x - 3y/4) = (8/5)x - 6y/20 = 1 (3/5)x - (3/10)y

Question 2: 1 (7/15)x

(4/5)x + (2/3)x = (12/15)x + (10/15)x = (22/15)x = 1 (7/15)x

Question 1: -2x + 3y

(3/4)(8x-4y) - (2/3)(12x - 9y) = 6x - 3y - 8x + 6y = -2x + 3y

Hope this helps!

Answer:

Question 7: Distributive

Question 5: [tex]1.2x+12.3y[/tex]

Question 3: [tex]$1\frac{3}{5}x -\frac{3}{10}y $[/tex]

Question 2: [tex]$1\frac{7}{15} x$[/tex]

Question 1: [tex]-2x+3y[/tex]

Step-by-step solution:

Question 7

[tex]4(x-5)=4x-20[/tex]

Distributive property, [tex]a(b + c) = ab + ac[/tex]. It says that multiplying the sum of two or more addends (numbers or terms added together) by a number (a) will give the same result as multiplying each addend individually. It is the same as the distributive property of multiplication over subtraction, except it will give the difference.

Question 5

[tex]2.4(3x + 2y) - 1.5(4x - 5y)[/tex]

Use the distributive property:

[tex]7.2x+4.8y-6x+7.5y[/tex]

[tex]1.2x+12.3y[/tex]

Question 3

[tex]$\frac{2}{5} \left(4x-\frac{3}{4}y \right)$[/tex]

Use the distributive property again:

[tex]$\frac{8}{5}x -\frac{6}{20}y $[/tex]

[tex]$\frac{8}{5}x -\frac{3}{10}y $[/tex]

Now you have to convert [tex]$\frac{8}{5} $[/tex] to mixed form:

It will give 1 with remainder 3, therefore

[tex]$\frac{8}{5} = 1\frac{3}{5} $[/tex]

[tex]$1\frac{3}{5}x -\frac{3}{10}y $[/tex]

Question 2

[tex]$\frac{4}{5} x +\frac{2}{3} x$[/tex]

[tex]$\frac{4(3)}{5(3)} x +\frac{2(5)}{3(5)} x$[/tex]

[tex]$\frac{12}{15} x +\frac{10}{15} x$[/tex]

[tex]$\frac{22}{15} x$[/tex]

Mixed form again:

[tex]$1\frac{7}{15} x$[/tex]

Question 1

[tex]$\frac{3}{4} (8x-4y) -\frac{2}{3} (12x - 9y)$[/tex]

[tex]$6x-3y -8x +6y$[/tex]

[tex]-2x+3y[/tex]

Answer:

slope =2

y intercept = (0,-4)

Step-by-step explanation:

y = 2x - 4

Since this is in the form y = mx+b where m is the slope and b is the y intercept

The slope is 2 and the y intercept is -4

slope =2

y intercept = (0,-4)

List the factors of 12

1,12

2,6

3,4

That is the side lengths of the 3 rectangles

All the areas will be 12 because they are the factors 12

factors multiply to be a number

(length + width) x 2 = perimeter

1+12=13x2=26

1 by 12 has a perimeter of 26 and area of 12

2 by 6 has a perimeter of 16 and area of 12
