Answer:

Step-by-step explanation:

[tex]f(x)=-4x+7[/tex]

To find f(1) , substitute the value of x that's 1 into f(x), that is for every x in f (x) replace it with 1

We have

[tex]f(1) = - 4(1) + 7 \\ = - 4 + 7 \\ = 3 \: \: \: \: \: \: \: \: \: \: \: [/tex]

We have the final answer as

[tex]f(1) = 3 [/tex]

Answer:

$5

Step-by-step explanation:

You will multiply $8 by 3 and subtract 44 by that number. You will then divide that number by 4.

Answer:

$5 each

Step-by-step explanation:

total of $44.00

3 adults * $8.00 = $24

$44.00 - $24.00 = $20

$20 * 4 children = $5 each

Answer:

Step-by-step explanation:

A.

Option A is correct. The property that justifies step 4 based on the calculation is the Commutative property of addition.

Equations are expressions separated by an equal sign.

Given the equation:

2(x-3) + 3x = 19

Expand the parenthesis using the distributive law

2x - 2(3) + 3x = 19

2x - 6 + 3x = 19

Collect the like terms

2x + 3x -6 = 19

Step 4

Since 2x+3x = 3x+2x = 5x (according to the commutative law), the expression becomes:

5x-6 = 19

Step 5

Add 6 to both sides

5x-6+6 = 19+6

5x = 25

x = 25/5

x = 5

Hence the property that justifies step 4 based on the calculation is the Commutative property of addition.

Answer:

(0,-16)

Step-by-step explanation:

Answer:

y = 4x - 19

Step-by-step explanation:

Find the y-intercept

y = mx + b

-11 = 4 * -2 + b

-11 = -8 + b

-19 = b

Now, rewrite the equation

y = 4x - 19

Answer:

6

Step-by-step explanation:

You substitute the points into the distance formula. There aren't decimals in this answer, so I don't think you need to round to the nearest tenth. You can also check by plotting these points down on a graph.

(4, -1) (-2, -1)

The y coordinates are the same, you just need to count from -2 to 4. There are 2 steps before 0 and 4 steps after 0. So 2 + 4 is 6.

===========================================

Work Shown:

[tex]\text{Distance Formula}\\\\d = \sqrt{(x_1-x_2)^2 + (y_1-y_2)^2}\\\\d = \sqrt{(4-(-2))^2 + (-1-(-1))^2}\\\\d = \sqrt{(4+2)^2 + (-1+1)^2}\\\\d = \sqrt{(6)^2 + (0)^2}\\\\d = \sqrt{36}\\\\d = 6\\\\[/tex]

This value is exact. No rounding is needed.

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

A shortcut is to subtract the x coordinates and apply absolute value

So either |x1-x2| = |4-(-2)| = |4+2| = |6| = 6

Or |x2-x1| = |-2-4| = |-6| = 6

This shortcut only works because the y coordinates the same for both points.

On a graph, you can plot the two points and count the spaces between them. You should count out 6 spaces.

Answer:

No Solution

Step-by-step explanation:

8x-3(1+6x) -2>5(1+2x)

-10x-5>-5-10x

(Add 5 to both sides)

-10>-10x

(Add 10x to both sides)

-10x+10x>-10x+10x

Therefore , this equation has no solutions.

Answer:

Answer:

Step-by-step explanation:

100800

1008 can s can be produced in a 7 hour day.

Just divide 1 second by 1000 which is 0.001 secs.It can also be called as 1 millisecond.

According to the given question aluminium, inc. produces cams at a rate of  0.04 per hundredth of a second. this can be numerically expressed as

0.04 cans produced in 0.01 seconds.

We know 7 hour is = (7×3600) seconds which is = 25200 seconds.

∴ In 7 hours aluminum, inc. can produce (25200 × 0.04) which is

= 1008 cans.

Step-by-step explanation:

The first step is to line it up in the Pythagorean theorem, then you want to move the [tex]6^{2}[/tex] to the other side of the equation via subtraction from both sides in order to isolate the [tex]x^2[/tex]. After that, you'll end up with [tex]x^{2} =64[/tex] then you'll want to square root both sides and end with [tex]x=8[/tex].

Answer:

Here's how to solve it.

Step-by-step explanation:

Okay,

from what I understand she has 20 train cars total.

She uses 5 for each train.

So to solve you use simple division.

20 / 5 = 4

To check your answer substitute 4 in the equation so 4 × 5 does equal 20.

So it would be 4.

5) =========================

Answer:

1.) C

2.) C

3.) A

5.) B

Step by-step explanation:

1.) because 14 is positive and the opposite of 12 is -12. So 14+-12=2!

2.) to get to 7 from -7 you would have to take 7 units to get there.

3.)Given that a football player caught the ball and made a gain of 8 yards on the first play. On the next play the team lost 12 yards.we are to find the number of yards needed to gain on the next play to get back to their original position.Let, x be the number of yards that the team had originally.On the next play, the team lost 12 yards, let 'k' be the number of yards  needed to gain on the next play to get back to their original position.Thus, the number of yards needed to gain on the next play to get back to their original position is 4.

5.) We have been given that on Monday morning the temperature was 38°F, but by the afternoon the temperature had risen 22°F. We are also told that on Tuesday morning the temperature had dropped 27°F since Monday afternoon.Since the temperature rose  by the Tuesday noon, so temperature by Tuesday noon will be 10 degrees greater than temperature by Tuesday morning.To find the number of degrees temperature is above or below 38°F on Tuesday at noon we will subtract 38°F from the temperature on Tuesday at noon. Since the difference between temperature is positive, therefore, the temperature on Tuesday at noon was 5 above .

Answer:

No solution.

-22x      -22x

52=89                   The answer comes out as 52=89, but 52 is not equal to 89.

When this happens, there is no solution.

The third pattern because you can divide 12 by the number of shapes in the sequence and start counting from the remainder.

In this case choice C has 5 shapes. 12/5 is 2, with a remainder of 2.

The second term in choice C is Circle, so choice C is the answer.

Of course, you can also list them all out.

If there is no remainder when you divide then the 12th term is the last term in the sequence.

Answer:

yes

Step-by-step explanation:

Answer with step-by-step explanation:

M = 32

Step 1: Simplify both sides of the equation.

3(m+2)=5m−58

(3)(m)+(3)(2)=5m+−58(Distribute)

3m+6=5m+−58

3m+6=5m−58

Step 2: Subtract 5m from both sides.

3m+6−5m=5m−58−5m

−2m+6=−58

Step 3: Subtract 6 from both sides.

−2m+6−6=−58−6

−2m=−64

Step 4: Divide both sides by -2.

−2m/−2=−64/−2

m=32
