Answer:

a = 0 and b = literally any number

Step-by-step explanation:

because anything to the power of 0 = 1,

so e.g. 2^0 = 1 or 8^0 = 1

this is just a rule in powers that you just have to know

and for part b anything × 0 = 0, so it can be anything

Answer:

x = 2.5

Step-by-step explanation:

y varies directly with x means the times that y increases, the times x increases and vice versa.

If y increases from 3/5 to 12 is being increased:

12 / 3/5 = 20 times

Thus, the value of x is being increased by definition, also 20 times. The value of x is:

x = 0.125 * 20 = 2.5

Answer:

5×4= 20+100=120

10×4=40+40=80

120 is more than 80

After 4 weeks , Josiah has 40 dollars more in his savings account.

Given :

Josiah starts with $100 in his savings account and adds 5 per week.

Let x be the number of weeks they started saving

Total money in savings account = 5 (number of weeks) + initial amount

Total money = [tex]5x+100[/tex]

Kiri starts with 40 in her savings account and adds 10 each week.

Total money = 10x+40

Now we need to find out how much money each have after 4 weeks

lets replace x by 4

Josiah have [tex]5(4)+100=120[/tex]

Kiri have [tex]10(4)+40= 80[/tex]

120-80=40

So , Josiah have 40 dollars more  in his savings account.

[tex]\boxed {\boxed {\sf 9 \ arrangements }}[/tex]

Step-by-step explanation:

Let's set up a proportion using the following setup:

[tex]\frac{arrangements}{minutes} =\frac{arrangements}{minutes}[/tex]

We know that the florist can arrange 4 in 92 minutes.

[tex]\frac{4 \ arrangements}{92 \ minutes} = \frac{arrangements}{minutes}[/tex]

We don't know how many the florist can arrange in 207 minutes, so we say x arrangements can be completed in 207 minutes.

[tex]\frac{4 \ arrangements}{92 \ minutes} = \frac{ x \ arrangements}{ 207 \ minutes}[/tex]

[tex]\frac{4}{92} =\frac{x}{207}[/tex]

Solve for x by isolating it on one side of the proportion.

x is being divided by 207. The inverse of division is multiplication. Multiply both sides of the proportion by 207.

[tex]207*\frac{4}{92}=\frac{x}{207}*207[/tex]

[tex]207*\frac{4}{92}=x[/tex]

[tex]207*0.0434782609=x[/tex]

[tex]9=x[/tex]

The florist can arrange 9 arrangements in 207 minutes.

Mathematical functions are analogous to vending (soda) machine operations. When you put in a certain amount of money, you can choose from a variety of sodas. Similarly, when we use functions, we enter different numbers and get new numbers as a result. The primary characteristics of functions are domain and range. A soda can be purchased with quarters or one-dollar bills. If you put in pennies, the machine will not give you any soda flavor. As a result, the domain represents the inputs available here, which are quarters and one-dollar bills. A cheeseburger will not be served from a soda machine, no matter how much you pay.

Answer:

m<FAB = 75°

m<BAC = 105°

Step-by-step explanation:

First, find the value of x.

(13x - 3)° = (3x + 2)° + 55° (exterior angle theorem of a ∆)

Solve for x

13x - 3 = 3x + 2 + 55

13x - 3 = 3x + 57

Collect like terms

13x - 3x = 57 + 3

10x = 60

Divide both sides by 10

x = 6

✔️m<FAB = 13x - 3

Plug in the value of x

m<FAB = 13(6) - 3 = 78 - 3

m<FAB = 75°

✔️m<BAC = 180 - m<FAB (angles on a straight line/supplementary angles)

m<BAC = 180 - 75 (substitution)

m<BAC = 105°

Step-by-step explanation:

x=4 and y= 1 because of 4+1=5 and add 2y to both sides

x-2y+2y=2+ 2y

x=2y+2

4-2=2

[tex]\left \{ {{x+y=5} \atop {x-2y=2}} \right.[/tex]

Here we have 2 equations in one system.

System of Equations/Simultaneous Equations are for finding the intercepts of both graphs.

We can solve these Simultaneous Equations in many ways. However, I'll be solving by substitution.

To solve by using substitution, we need to move either x or y to the another side. I'll move x term to another side for the first equation. (We'll substitute the first equation in the second.)

[tex]\left \{ {{y=-x+5} \atop {x-2y=2}} \right.[/tex]

Now we substitute y = -x+5 in x-2y = 2

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

Then distribute -2 in (-x+5) | Note that multiplying the negative will get positive. |

[tex]x-2(-x+5)=2\\x+2x-10=2\\3x=2+10\\3x=12[/tex]

We should get this. When we get this, we move 3 to divide 12 (Opposite when moving to another side so from plus to minus and from multiply to divide.)

[tex]x=4[/tex]

But we are not done yet. We have to find the y-value. After all they are two variables equations.

If we want to find the y-value then we have to substitute x = 4 in any given equations. I'd suggest to substitute in the equation that doesn't have a coefficient with high value.

So I'll be substituting in x + y = 5 instead.

Substitute x = 4 in x + y = 5

[tex]4+y=5\\y=5-4\\y=1[/tex]

Thus, we get both x and y value. Answer in either coordinate point or writing form.

Therefore, the answer is

x = 4 when y = 1 or (4,1)

Both works. Hope this helps.

Answer:

Space Explorer B travels 6800 miles more than Space Explorer A in one hour.

Step-by-step explanation:

Space Explorer A travels 7000 miles less than Space Explorer B in one hour.

Two or more expressions with an equal sign are defined as an equation.

Given that, Space Explorer A flies 28800 miles in 24 hours.

24 hours = 28800 miles

1 hour = 28800/24 miles

1 hour = 1200 miles

Hence, Space Explorer A travels 1200 miles in 1 hour.

Now, the equation representing the distance, y, traveled by Space Exploral B in x hours is:

y = 8200x

Substitute x = 1:

y = 8200

Therefore, Space Exploral B travels 8200 miles in 1 hour.

The difference between the distance traveled by Space Exploral B and Space Exploral A is:

8200 - 1200

= 7000

Hence, Space Explorer A travels 7000 miles less than Space Explorer B in one hour.

The annual interest rate on a loan of $ 25,500 if the interest payments are $ 956.25 will be equal to 3.75 %.

We are given that the principal loan amount is equal to $ 25,500

That is

Principal = p = $ 25,500.

The interest payments is $ 956.25

That is the amount of interest = SI = $ 956.25.

Let the rate of interest on the loan amount be r.

Time period = t = 1

Simple Interest = p r t / 100

956.25 = 25,500 × r × 1 / 100

956.25 = 255 r

r = 956.25 / 255

r = 3.75 %

Therefore, the annual interest rate on a loan of $ 25,500 if the interest payments are $ 956.25 will be equal to 3.75 %.
