Answer:

  -14x² +19x

Step-by-step explanation:

You want the sum of the expressions (-8x² +9x) and (-6x² +10x).

The sum is found by adding like terms: terms with the variable to the same power.

  (-8x² +9x) + (-6x² +10x)

  = (-8 -6)x² +(9 +10)x

  = -14x² +19x

To graph the logarithmic function y = log₂(x), we can use the key point (1,0) and the fact that the logarithmic function is the inverse of the exponential function y = 2ˣ.

Starting at the key point (1,0), we can move to the right by increasing x by a factor of 2, since log₂(2) = 1. This takes us to the point (2,1). Similarly, we can move to the right by a factor of 2 again to get to the point (4,2), and then to (8,3), (16,4), and so on.

If we instead move to the left from the key point (1,0) by a factor of 2, we get to the point (1/2, -1), since log₂(1/2) = -1. We can continue moving to the left by dividing x by 2 to get to (1/4, -2), (1/8, -3), and so on.

The given graph of y = log₂(x) using only integer points.

The graph is symmetric about the line x=1, since log₂(x) = log₂(1/x) = -log₂(x).

The total measure of angles in a triangle is 180°.

3x° + 2x° + 4x° = 180°

9x° = 180°

x° = 180° ÷ 9

x° = 20

Our 3 angles are:

3(20) = 60°

2(20) = 40°

4(20) = 80°

Done.

Answer:

14[tex]\frac{2}{7}[/tex]%

Step-by-step explanation:

We can just follow the hint.

Amount of discount = $84 - $72

                                 = $12

Percentage of discount = [tex]\frac{12}{84}[/tex] × 100%

                                       = 14[tex]\frac{2}{7}[/tex]%

Answer:

14.3% discount.

Step-by-step explanation:

Heya! So by the hint that they gave us, I subtracted 72 from 84, and then divided the 12 by 84. The true answer is 0.143 (rounded to the hundredth), getting you close to the initial 12. I hope this helped at least a little bit!

Hey there!

“-3 < x - 10”

SOME people treat the “<” “>” as an equal sign to make these types of problems easier to solve!

-3 = x - 10

Flip the equation around

x - 10 = -3

ADD both of your sides by 10

Like: x - 10 + 10 = -3 + 10

CANCEL out: -10 + 10 because it gives us 0

Keep: -3 + 10 because it gives us the value of x

-3 + 10 = x

Solve that above and you have your answer: x = 7 ☑️

Overall answer: x < 7

Good luck on your assignment and enjoy your day!

Using creamers rule of determinants, we have;

D =

|1 1|

|2 3|

Thus; D = (1 × 3) - (1 × 2)

D = 1

Dx =

|2 1|

|4 3|

Dx = (2 × 3) - (1 × 4)

Dx = 2

Dy =

|1 2|

|2 4|

Dy = (1 × 4) - (2 × 2)

Dy = 0

Thus;

x = Dx/D = 2/1

x = 2

y = Dy/D = 0/1

y = 0

Answer: 100√6

Step-by-step explanation:

Start out by multiplying the 2 by the 10 to get 20.

Then, multiply √5 and √30 together to get √150. The largest perfect square within √150 is √25 (don't forget about your √6)

√25 is 5. Multiply your 20 and 5 together to get 100, and then put your √6 next to the 100 since it cannot be added or multiplied since they are not like-terms.

Thus, leaving you with an answer of 100√6.

Answer:

4(n + 3) = 60

Step-by-step explanation:

In the question it says '3 more than the usual' and that is a big hint that it is 4(n + 3) = 60

Grant will make $63 commission on 12 trees he sold.

Given that, Grant works as a salesperson at a seasonal market. He gets a 15 percent commission on every tree he sells. If he sold 12 trees then we have to calculate the amount of commission he will get if the average sales price of a tree is $35.

So, first we will calculate the amount of commission Grant will get if he sold one tree.

∴ The commission on one tree will be equals to 15 percent on the sales price of a tree i.e., $35.

⇒ 15% of $35

= 15/100 x 35

= 5.25

Therefore, Grant will get $5.25 commission on selling one tree.

He sold 12 trees on that day. So, the total amount of commission he will get on 12 trees will be equal to,

= 12 x 5.25

= 63

Therefore, $63 is the amount of commission Grant will made on the sale of 12 trees.

Answer:

12 dark chocolates

Step-by-step explanation:

Let there are 2x milk chocolates and 3x dark chocolates.

Total no of milk chocolates = 8

ATQ,

2x = 8

x = 4

Dark chocolates = 3x

= 3(4)

= 12

Hence, there are 12 dark chocolates.

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.

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.
