What’s the answer to this?

Answer:

2x-8

Step-by-step explanation:

The word "from" tells you that the first part of the sentence should be at the back of the equation because you're taking from the product of 2 times a number, the number is unknown so it is known as "x."

Answer:

8.06

Explanation:

For this question, you have to use the distance formula

Answer:

8.06

Step-by-step explanation:

To find the distance between two points, you would use the distance formula.

The distance formula is:

[tex]\sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2}}[/tex]

where (x₁, y₁) and (x₂, y₂) are two points.

Lets plug in the points (3, -1) (x₁, y₁) for  (7, -8) for (x₂, y₂):

[tex]\sqrt{(7-3)^{2}+((-8)-(-1))^{2}}[/tex]

= [tex]\sqrt{4^{2}+(-7)^{2}}[/tex]

= [tex]\sqrt{16+49}[/tex]

= [tex]\sqrt{65}[/tex]

≈ 8.06225775

Rounded to the nearest hundredth, it is 8.06.

So the distance between the points B and C rounded to the nearest hundredth is 8.06.

I hope you find my answer helpful.

Answer:

470.273

Step-by-step explanation:

Given the following :

Amount of loan = $15,000

Interest rate = 2.5%, compounded monthly

Period = 1 year, 2 months, 25 days

Using the compound interest formula:

A = P(1 + r/n)^(n*t)

A = final amount, p = principal

r = interest rate ; n = number of times Interst is compounded per time period

t = number of time period elapsed

Period = 1 year, 2 months, 25 days since the

Hence, t = 1+(2÷12)+(25÷(30×12))

A = 15000(1 + 0.025 / 12)^(12×1.2361111)

A = 15000(1 + 0.0020833)^14.833333

A = 15000(1.0020833)^14.833333

A = 15000(1.0313515)

A = 15470.273

Hence, Interest equals :

15470.273 - 15,000

= 470.273

Step-by-step explanation:

Answer:

perpendicular

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3x = y - 5 ( add 5 to both sides )

3x + 5 = y ← in slope- intercept form

with slope m = 3

------------------------------------------------

9y + 4x = x - 9 ( subtract 4x from both sides )

9y = - 3x - 9 ( divide all terms by 9 )

y = - [tex]\frac{1}{3}[/tex] x - 1 ← in slope- intercept form

with slope m = - [tex]\frac{1}{3}[/tex]

-----------------------------------------------

Parallel lines have equal slopes

The product of the slopes of perpendicular lines = - 1

Thus

the slopes are not equal, thus not parallel lines.

3 × - [tex]\frac{1}{3}[/tex] = - 1 , hence lines are perpendicular

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = F(2, 11) and (x₂, y₂ ) = G(5, 16)

d = [tex]\sqrt{(5-2)^2+(16-11)^2}[/tex]

   = [tex]\sqrt{3^2+5^2}[/tex]

   = [tex]\sqrt{9+25}[/tex]

   = [tex]\sqrt{34}[/tex] ≈ 6 ( to the nearest whole number )

Given:

The absolute value equation is

[tex]|x|-2=5[/tex]

To find:

The distance Mary can walk forward, i.e., x.

Solution:

We have,

[tex]|x|-2=5[/tex]

Add 2 on both sides.

[tex]|x|-2+2=5+2[/tex]

[tex]|x|=7[/tex]

[tex]x=\pm 7[/tex]

[tex]x=-7[/tex] and [tex]x=7[/tex]

Here, negative sign represents the distance Mary can walk reverse direction.

Therefore, the correct option is A.

Answer:

8

Step-by-step explanation:

Number x Square x2 Cube x3

2          4                       8

Answer: X=-3

Step 1) Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

5*(x-4)+3*x-9*x-(6-(2*x+5)+8*x)=0

Step 2) ((5 • (x - 4) +  3x) -  9x) -  (6x + 1)  = 0

Step 3)  Pull out like factors :   -7x - 21  =   -7 • (x + 3)

Step 4)  -7 • (x + 3)  = 0

Step 5)  Solve :    -7   =  0  This equation has no solution.

A a non-zero constant never equals zero.

Step 6) Solve  :    x+3 = 0  

 Subtract  3  from both sides of the equation :  

x = -3

Answer:

The humpback whales are 37 times bigger than the krills they eat

Step-by-step explanation:

In this question, we are interested in knowing how much bigger are humpback whales compared to krill.

what is simply happening here is to divide the weight of the humpback whales by the weight of the krills.

From the question, weight of humpback whales = 8 * 10^4 while the weight of the krills are 2.1875 * 10^3

So the number of times the humpback whales are bigger is;

(8 * 10^4)/(2.1875 * 10^3) = 36.57 which are approximately 37 times bigger

Answer:

(-0.5, 3)

Step-by-step explanation:

You can take the midpoint of the x and y separately, the same way as you calculate an average.

for x: (2 + -3) / 2 = -0.5

for y: (4 + 2) / 2 = 3

Answer:

No.

Step-by-step explanation:

A function must pass the Vertical Line Test. The equation given is a circle on the coordinate plane. Therefore, since there will be 2 points for the same x value, it will not be a function.

Answer:

2.6%

Step-by-step explanation:

CP of each phone =2000

total cp = 4000

in 1st case

profit = 10 %

so,sp = cp + 10 % of xp

= 2000 + 10/100 ×2000

= 2200

in 2and case

loss =5%

so sp=cp - 5% of cp

=2000 - 5/100 × 2000

=1900

so total sp = 4100

so profit % = sp - cp/cp ×100%

= 2.5

Step-by-step explanation:

if both y and x are 0 than it is true that they equal each other since 0=0

Explanation:

p(-6) = 0 means that plugging x = -6 into p(x) leads to p(x) = 0.

If (x+6) was a factor of p(x), then we can say

p(x) = (x+6)q(x)

where q(x) is some other polynomial. Now let's replace x with -6

p(x) = (x+6)q(x)

p(-6) = (-6+6)q(-6)

p(-6) = 0*q(-6)

p(-6) = 0

The value of q(-6) doesn't matter as multiplying 0 with any number leads to 0.

This is all based on the special case of the remainder theorem that says "if p(k) = 0, then (x-k) is a factor of p(x)".

(x+6) is a factor of p.

The answer is option C.

p(-6) = 0 means that plugging x = -6 into p(x) leads to p(x) = 0.

If (x+6) was a factor of p(x), then we can say

p(x) = (x+6)q(x)

where q(x) is some other polynomial. Now let's replace x with -6

p(x) = (x+6)q(x)

p(-6) = (-6+6)q(-6)

p(-6) = 0*q(-6)

p(-6) = 0

The value of q(-6) doesn't matter as multiplying 0 with any number leads to 0.

This is all based on the special case of the remainder theorem that says "if p(k) = 0, then (x-k) is a factor of p(x)".

Answer:

x = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

Given

[tex]\frac{3}{2}[/tex](4x - 2) - 3x = 5 - (x + 2) ← distribute parenthesis on both sides

6x - 3 - 3x = 5 - x - 2 , that is

3x - 3 = 3 - x ( add x to both sides )

4x - 3 = 3 ( add 3 to both sides )

4x = 6 ( divide both sides by 4 )

x = [tex]\frac{6}{4}[/tex] = [tex]\frac{3}{2}[/tex]
