A simple algebra equation!

You have to replace each x with 4, so the equation would look like this:

-4·4+1.5·4-2.5-2·4-6.5

Evaluate the terms, you get:

-16+6-2.5-8-6.5

Then you add and subtract where needed:

-10-16 = -27

And that's the final answer!

ANSWER: 27

Answer:

Step 1 - Find Whole Number

Calculate out how many times the denominator goes into the numerator. To do that, divide 6 by 5 and keep only what is to the left of the decimal point:

6 / 5 = 1.2000 = 1

Step 2 - Find New Numerator

the answer from Step 1 by the denominator and deduct that from the original numerator.

6 - (5 x 1) = 1

Step 3 - Get Solution

Keep the original denominator and use the answers from Step 1 and Step 2 to get the answer. 6/5 as a mixed number is:

Answer as a compound inequality: [tex]-4 \le y < 2[/tex]

Answer in interval notation:  [-4, 2)

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

Explanation:

The range is the set of all possible y outputs of a function. When dealing with a graph like this, we just look at the highest and lowest points to determine which y values are possible.

The lowest point occurs when y = -4. We include this value. So far we have [tex]y \ge -4[/tex] which is the same as [tex]-4 \le y[/tex]

The upper ceiling for the y value is y = 2. We can't actually reach this value because of the open hole at (-3,2). So we say that [tex]y < 2[/tex]

Combine [tex]-4 \le y[/tex] and [tex]y < 2[/tex] to get the compound inequality [tex]-4 \le y < 2[/tex]

This says y is between -4 and 2, including -4 but excluding 2.

To convert this to interval notation, we write [-4, 2) where the square bracket says to include the endpoint and the curved parenthesis says to exclude the endpoint.

Answer:

Step-by-step explanation:

The first probability of it being red = 5/11

The key to the question is that you replace the red marble you took out. So there are still 5 red marbles.

You still have a 5/11 chance of getting a red marble.

P(red + red) = 5/11 * 5/11

Answer

P(red + red) = 25 / 121

Answer:

Step-by-step explanation

Perpendicular lines have slopes that are negative reciprocals of one another.

so, in this case, the given slope is 2.

The negative reciprocal of that would be -1/2.

so far, our equation looks like: y=-1/2x+b

now, take the point given to us, (-4,2) and plug it into the y and x values.

2= -1/2(-4) +b

2= b+2

b=0

Our y intercept is zero, so our final answer will be:

[tex]y=-\frac{1}{2} x[/tex]

Answer:

C 13

Step-by-step explanation:

2 right-angled triangles. so, Pythagoras applies for both.

c² = a² + b²

with c being the Hypotenuse (the side opposite of the 90° angle).

starting with the small triangle we have

5² = 3² + x-part²

x-part² = 5² - 3² = 25 - 9 = 16

x-part = 4 cm

the markers indicate that x-part as the third side of the small triangle is exactly as long as the other part of x.

that means

x = 2 × x-part = 2 × 4 = 8 cm

for the large triangle we then get

y² = x² + 15² = 8² + 225 = 64 + 225 = 289

y = 17 cm

and so,

y - x = 17 - 8 = 9

but that is not an answer option.

and now it dawned on me : x was not meant to be the whole third side of the large triangle. x is supposed to be only the upper part of that side, above the small triangle.

in essence, x is what I originally called "x-part".

so, the Pythagoras calculations remain basically the same, but we should name things differently like

5² = 3² + small-side²

small-side = 4 cm

x = small-side = 4 cm

long-side = 2 × small-side = 2 × 4 = 8 cm

y² = long-side² + 15² = 8² + 15² = 64 + 225 = 289

y = 17 cm

and the actual y - x = 17 - 4 = 13 cm

The inequality which is used to find the number of cups of yogurt Monica can buy is,

[tex]1.20x+2.5\leq20[/tex]

Inequality equation is the equation in which the two expressions are compared with greater than, less than or other inequality signs.

Monica needs to buy a gallon of milk that costs $2.50. She also wants to buy yogurt, which costs $1.20 a cup. Let suppose the number of cups of yogurt bought by Monica is x.

As she has only $20. Thus, the inequality expression which can be used for this condition is,

[tex]1.20x+2.5\leq20[/tex]

Solve the above equation and find the value of x,

[tex]1.20x\leq20-2.5\\1.20x\leq17.5[/tex]

Divide both side with 1.20,

[tex]x\leq\dfrac{17.5}{1.20}\\x\leq14.58\overline3[/tex]

Hence, the number of cups she can Monica is 14.

Thus, the inequality which is used to find the number of cups of yogurt Monica can buy is,

[tex]1.20x+2.5\leq20[/tex]

Answer:

HOPE THIS HELPS

Step-by-step explanation:

You need to first plot the points on the graph.

Since, it says you need to reflect across x axis, you need same number of square units.

For example, P has the coordinates( -2,3 ). -2 lies on the x axis, so the point doesn't go neither left nor right. It is 3 squares above the x axis, so the reflected point should be 3 squares below the x axis. Likewise, you can do the other points.

The Carlos pay in service charges is $1721.3  

We have given that the Carlos took seven years to pay off his loan by making identical quarterly payments.

The loan had a principal of $22,375 and 5.49% interest, compounded quarterly.

P=22375 and interest rate =5.49%

Carlos paid a total of $28,821.67.  

We have to find how much did Carlos pay in service charges

First we find the monthly payment of the loan

The formula for monthly payment is,

[tex]M=\frac{amount}{discount}[/tex]

Discount factor

[tex]P=\frac{1-(1+i)^{-n}}{i} \\[/tex]

Where, Amount = $22,375 and r=0.0549 and compounded quarterly therefore n=4

[tex]i=r/n=0.0599/4[/tex]

i=0.0137

Time =7 years

[tex]n=4\times 7=28[/tex]

Now put all the values in above formula we get

[tex]P=\frac{1-(1+0.01372)^{-28}}{0.01372}\\\\P=\frac{1-(1+0.1372)^{-28}}{0.01372}\\\\P=\frac{1-0.6827}{0.01372}\\\\P=\frac{0.3172}{0.01372}\\\\P=23.11[/tex]

Monthly payment,

Use the value in the formula of monthly payment

[tex]M=\frac{22375}{23.1177}[/tex]

[tex]M=967.871[/tex]

The payment he has for for 7 years compounded quarterly that is  for 28

Therefore the payment,

[tex]Payment= 967.871 \times 28 = $27100.39[/tex]

[tex]Service charges = Total payment - payment[/tex]

                           [tex]= $28,821.67 - $27100.39[/tex]

                           [tex]= $1721.27[/tex]

Therefore, Carlos pay in service charges is $1721.3

Length of board will be 32 1/2 inch.

What is Addition?

A process of combining two or more numbers is called addition.

Given that;

Length of board after cutting are;

7 1/2 inches, 10 1/2 inches, 9 inches, and 5 1/2 inches.

Now, Total length of board is calculated as sum of all cut lengths.

So, Total length of board = 7 1/2 +10 1/2 + 9 + 5 1/2

                                      = 15/2 + 21/2 + 9 + 11/2

                                      = 47/2 + 9

                                      = 65/2

                                      = 32 1/2

Thus, Length of board will be 32 1/2 inch.
