Use the order of operations to evaluate this expression: 7 + (5 – 9)2 + 3(16 ÷ 8).​

Answer:

You have to multiply the last number by 3. So 9 times 3 equals 27 and 27 times 3 equals 81 and so on. The answer would be 59,049

Answer:

25 i think

Step-by-step explanation:

1 Remove parentheses.

3d-2=d+5

2 Add 22 to both sides.

3d=d+5+2

3 Simplify  d+5+2  to  d+7.

3d=d+7

4 Subtract d from both sides.

3d-d=7

5 Simplify  3d-d to  2d.

2d=7

6 Divide both sides by 2.

7/2=d

7 Flip sides.

d=7/2

(Optional decimal form)

d=3.5

So 7/2 or 3.5

Answer:

-145/88z+4

Step-by-step explanation:

Answer: -4/11z - 4

Step-by-step explanation: We can combine like terms to simplify the expression 2/11z - 5/11z + 4 - 1/11z - 8. The terms 2/11z, -5/11z, and -1/11z are like terms because they all have the same variable part z. When we add them together, we get (2 - 5 - 1)/11z = -4/11z. The constants 4 and -8 are also like terms. When we add them together, we get 4 + (-8) = -4. So the simplified expression is -4/11z - 4.

Answer:

$68,213

Step-by-step explanation:

The median is the middle value number.

So you need median for Virginia.

First lets see how index and income are connected.

To do this divide the income by the index to see if you have a constant value you can use.

535.434783 = Arkansas

535.381944 = Alabama

535.58 = Arizona

535.669236 = Alaska

535 is constant in all of these.

Let's multiply the index by 535.

127.2*535 =68212.5

For median income, you need a whole number so lets round up.

68213

So Virginia would have a median income rate of $68,213

Given:

Candle A comes out of the mold at 211 ​mm, and is expected to be at 187 mm after 8 hours of burning.

The model for Candle B is

[tex]h=210-5t[/tex]

where, h is the height in millimeters and t is the time in hours.

To find:

The initial values for each​ candle and its interpretation.

Solution:

Candle A comes out of the mold at 211 ​mm, and is expected to be at 187 mm after 8 hours of burning.

So, initial value of candle A = 211 mm

The model for Candle B is

[tex]h=210-5t[/tex]

Putting t=0, we get

[tex]h=210-5(0)[/tex]

[tex]h=210-0[/tex]

[tex]h=210[/tex]

So, initial value of candle B = 210 mm

Initial values for each candle tell​ you about the height of the candles before they start burning.

Initial value of candle A is greater than B, so the height of candle A is greater than B before they start burning.

Therefore, the initial value of candle A is 211 mm and initial value of candle B is 210 mm.

Answer:

The cost of one daylily is $10 and the cost of one pot of ivy is $11

Step-by-step explanation:

To solve the question we will form a system of equations

Assume that the cost of 1 daylily is x and the cost of 1 pot of ivy is y

∵ Sumalee spent $93 on 6 daylilies and 3 pots of ivy

→ Multiply x by 6, y by 3, then add the products and equate the sum by 93

∴ 6x + 3y = 93 ⇒ (1)

∵ Scott spent $196 on 13 daylilies and 6 pots of ivy

→ Multiply x by 13, y by 6, then add the products and equate the sum by 196

∴ 13x + 6y = 196 ⇒ (2)

Now we have a system of equations to solve it

→ Multiply equation (1) by -2

∵ -2(6x) + -2(3y) = -2(93)

∴ -12x - 6y = -186 ⇒ (3)

→ Add equations (2) and (3)

∵ (13x + -12x) + (6y + -6y) = (196 + - 186)

∴ x + 0 = 10

∴ x = 10

→ Substitute the value of x in equation (1) to find the value of y

∵ 6(10) + 3y = 93

∴ 60 + 3y = 93

→ Subtract 60 from both sides

∵ 60 - 60 + 3y = 93 - 60

∴ 3y = 33

→ Divide both sides by 3

∴ y = 11

∴ The cost of one daylily is $10 and the cost of one pot of ivy is $11

Answer:

The image coordinates are:

A'(0, 0)

B'(-8, -8)

C'(4, -8)

The graph of the image coordinates attached below.

The image triangle A'B'C' is illustrated in green color.

Step-by-step explanation:

Let the points of a triangle be

We need to determine the graph of the image of this triangle after a dilation with a scale factor of 2 centered at the origin.

A dilation by a scale factor of 2 centered at the origin means the coordinates of the image can be obtained by multiplying the original coordinates with 2.

Next, the rule of dilation by a scale factor of 2 is given by

Dilation: (x, y)  →  (2x, 2y), centered at (0, 0)

P(x, y)  → P' (2x, 2y)

A(0, 0) → A' (2(0), 2(0)) → A'(0, 0)

B(-4, -4) → B' (2(-4), 2(-4)) → B'(-8, -8)

C(2,-4) → C' (2(2), 2(-4)) → C'(4, -8)

Therefore, the image coordinates are:

The graph of the image coordinates attached below.

The image triangle A'B'C' is illustrated in green color.

Answer:

Mia's score is 10

Step-by-step explanation:

Mia and Evette played a game in which they scored 10 points for each correct answer and lost 20 points for an incorrect answer. Mia answered 7 questions correctly and 3 questions incorrectly. What was Mia's overall score? *

We are told that:

Correct points = 10 per answer

Incorrect points = 20 per answer

Mia answered 7 questions correctly and 3 questions incorrectly.

Hence:

7 (10) + 3(20)

= 70 points - 60 points

= 10 points

Mia's score is 10

since the number in the thousandths place is greater than four, you round the number in the hundredths place up to the number that would come after that. In this case, 8 rounds up to 9

Step-by-step explanation:

I'm going to explain this in standard slope intercept form (y=mx+b) because it is easiest for this situation. I will also include converting it to point slope form. I will also show how to do straight into point slope form if you find that more helpful.

First thing is to identify difference in x and y in both points. From point 1 to point to, the x changes -4 and the y changes +4. We can rapresent this in rise over run fraction

[tex] \frac{4}{ - 4} = - 1[/tex]

So the slope is -1 because the slope is the simplified rise over run fraction.

Our next step is to find the y-intercept. This is easy because the first point is the y-intercept, so -3 is our y-intercept.

Now we know the equation.

[tex]y = - x - 3[/tex]

All we have to do now is convert it into point-slope form. So here is point slope form: y + y1 = m(x + x1). Y1 is the y-intercept and m is the slope.

[tex]y - 3 = - 1(x + x1)[/tex]

So x1 is the x intercept, so to find this you find the x value when y is 0. You can do this by using the standard form I've done because it is easiest.

[tex]0 = - x - 3 \\ x = - 3[/tex]

So when y is 0, then x is -3. Here is the complete point slope form of the line.

[tex]y - 3 = - 1(x - 3)[/tex]

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

To put the line directly into point slope for you need to find the slope, y-intercept, and x-intercept and place the values in accordingly. If you aren't given the y-intercept and x-intercept straight away it can be difficult for some putting it directly in point slope form. That is why I recommend putting it into standard form then point-slope form.

Answer:

y=-1x-3

Step-by-step explanation:

First, you have to find the slope using the formula I attached. Using this formula, you will subtract the second y from the first y, which is 1-(-3) for this problem. That equals 4, so that will be the numerator of the slope. Next, you have to subtract the second x from the first x, which is -4-0 for this problem. That equals -4, so that will be the denominator for this slope. the fraction now is [tex]\frac{4}{-4}[/tex], which is -1. The slope is -1. The current equation looks like this: y=-1x+b. Now we can solve for b, or the y-intercept. To do this, you have to use the x and y of one of the coordinates, it doesn't matter which one, the answer will be the same. Use the first one, for example. The x is 0 and the y is -3, so the our equation to find b is -3=-1(0)+b, which is -3=0+b, which is -3=b, or b=-3. So now we know what b is. Now we have to two components we need to write the equation, the slope (-1) and the y-intercept (-3). Now we can write the equation. y=-1x+(-3), or y=-1x-3.
