Which expression is equivalent to 9–2? –81 –18 startfraction 1 over 81 endfraction startfraction 1 over 18 endfraction

Answer:

Step-by-step explanation:

f(-2)= x^2+2x-10= (-2)^2+2(-2)-10= 4-4-10= 0-10 = -10

The Correct answer is D because when you have 2 non value numbers and you go off the subtraction it is a sum

Answer:

D. Their Sum is Zero

Step-by-step explanation:

Answer:

4 Hours and 32 minutes

Step-by-step explanation:

Let's first find the amount between 9:15 to 2:17

The difference between 9:00 and 2: 00 is 5 Hours

Now the minutes ->  17-15 = 2

Thus, the difference is 5 Hour and 2 Minutes

Then She took a 30 minutes break for lunch.

Let's convent all to minutes:

1 Hour = 60

Then 60  x 5  = 300

Plus the 2 minutes is

302

Now 302 minutes - 30 minutes = 272 minutes

Now convent back to Hour

Thus, 272/60 =4 with a remainder of 32.

Hence, it took stephanie 4 hour and 32 minutes to finish her SOL test.

Answer:

[tex](4;3)[/tex]

Step-by-step explanation:

Add the two equations together

[tex]I+II: x+7y+2x-7y=25-13 \rightarrow 3x=12\rightarrow x =4[/tex]

At this point i'd rather replace x=4 in the first equation to get [tex]4+7y=25 \rightarrow 7y=21 \rightarrow y=3[/tex]

To keep eliminating you multiply the first by 2 and subtract the second

[tex]2\times I -II: 2x+14y-2x-(-7y)=50-(-13)\rightarrow 21y=63 \rightarrow y=3[/tex]

Answer:

hope you have understood

A rotation is a circular movement of an object around a center of rotation. A three-dimensional object can always be rotated about an infinite number of imaginary lines called rotation axes. If the axis passes through the body's center of mass, the body is said to rotate upon itself, or spin.

so for what type of girl did you give brainlist

D

if u use deductive reasoning you'll know. so u know looking at the line it's a positive slope cause the line is going up and u know the y intercept is positve 1 so u know it will be +1 knowing this and going through the answer choices D is the only one that fits that!

The correct explanation of the graph is;

y = 3/2 x + 1

Option D is true.

What is Equation of line?

The equation of line with slope m and y intercept at point b is given as;

y = mx + b

Given that;

The graph is shown in figure.

Two points on the graph are (2, 4) and (4, 7).

Now, Take two points on graph and find the slope of the graph as,

Two points on the graph are (2, 4) and (4, 7).

Hence, Slope of graph = (7 - 4) / (4 - 2)

                                   = 3/2

Thus, Slope of graph is 3/2.

Since the slope of graph is same as slope of equation.

Hence, In option D;

The equation is given as;

y = 3/2 x + 1

Slope of equation is find as differentiate with respect to x,

Slope of equation is;

dy/dx = m = 3/2

So, The correct explanation of the graph is;

y = 3/2 x + 1

Answer:

X is about 14.1

Step-by-step explanation:

Hi!

In order to solve this problem, we just have to take the square root of both sides:

x²=200

x times itself should equal 200.

And the answer is

x≈14.1

Answer: 211 miles

Step-by-step explanation: An equation for this could be:

base fee + additional charge (miles driven) = total charge

19.99 + 0.86(x) = 201.45

0.86(x) = 201.45 - 19.99

0.86(x) = 181.46

x = [tex]\frac{181.46}{0.86}[/tex] = 211 miles

Answer:

$134.40

Step-by-step explanation:

The markup is 28% of 105, or .28(105) = $29.40

Thus the retail price is $105 + $29.40 = $134.40

The price of the bookcase in the furniture store, after a 28% markup on the wholesale price, is $134.40.

To find the price of the bookcase in the furniture store after a 28% markup on the wholesale price, we need to add the markup amount to the wholesale price.

The markup amount is calculated by multiplying the wholesale price by the markup percentage (expressed as a decimal). In this case, the markup percentage is 28%, which is equivalent to 0.28 as a decimal.

Markup amount = Wholesale price * Markup percentage

Markup amount = $105 * 0.28

Markup amount = $29.40

Now, to find the price of the bookcase in the furniture store, we add the markup amount to the wholesale price:

Price in the furniture store = Wholesale price + Markup amount

Price in the furniture store = $105 + $29.40

Price in the furniture store = $134.40

Answer:

75 km

Step-by-step explanation:

Given the following :

Scale on first map = 1cm to 20 km

Distance fromFresno to San Francisco = 15km on first map

Scale on 2nd map = 1cm to 100 km

1cm / 20km = 15km

Let of Distance from Fresno to San Francisco on 2nd map = d

1cm / 100km = d

1 : 20 = 15

1 : 100 = d

20/ 100 = 15/d

1/5 = 15/d

d = 15 * 5

d = 75 km

Hey there!

C=πd

Where

C=Circumference

π=pi (3.14...)

d=diameter

So all we have to do is plug in the value of d and multiply π times 6:

C=π×6

C≈18.84 in

hmmm.

the picture tries to tell me that the 2 more or less horizontal lines are not parallel.

yet the answer options seem to indicate that they are parallel. otherwise none of the answer options make any sense.

so, assuming the 2 lines are meant to be parallel :

1 and 3 : corresponding angles.

2 and 7 : alternate interior angles.

8 and 3 : vertical angles.

4680 dollars

Step-by-step explanation:

Hello, I'd love to help you!
We know that:

-Original price is 7200 dollars

-Manuel only paid for 65% of it

   -> think of it this way: think of the overall price as a pie; Manuel only ate              65% of it

To calculate how much Manuel paid, we can multiply 7200 times 0.65 (percentage in decimal form), which equals 4680 dollars.
