Please help me simplify this equation!

Answer: E

Step-by-step explanation:

(-3^2) multiply -3 by itself to get -9

Now you have -2 x -9 or -2(-9)

Remember that multiplying a negative by a negative will get you a positive because the two negative signs are canceled out.

So -2(-9) gives you 18

Answer:

the answer is 1 and 7

Step-by-step explanation:

4 times 2 is 8 -7 =1

6 times 2 =12 -5 =7

Answer:

First problem equals 1 and second problem equals 7.

First multiply 4x2 to get 8, then subtract it by 7.  That would leave you with 1.

Now, 6x2 would be 12 minus 5 which would equal 7.

Answer:

In simplified/simplest form and in descending order, your answer would be: -4x^3 - 4y^2. Hope this helps!  

Answer:

options 3 and 4 are correct

Step-by-step explanation:

And form the remainder of the problem, you isolate x by just multiplying by the negative reciprocal, which is -3/2, or just dividing by the number in front off x, which is -2/3, which makes statements three and four true. so this makes this three and four options

I hope this helps you :)

Two options namely " After adding 4 to both sides, the equation is negative two-thirds negative 2" and the statement " the equation can be solved for x using exactly one more step by multiplying  both sides by Negative three-halves."

A linear equation is an algebraic equation where each term has an exponent of 1 and when this equation is graphed, it always results in a straight line. This is the reason why it is named as a 'linear equation'.

Given here  -4-2/3x +4=-6+4

                 ⇒-2/3x = -2

                 ⇒ -2/3x ×3/2 = -2 ×3/2

                 ⇒ x = 3

Hence the final answer is 3.

Answer:

(At least) 68 hours

Step-by-step explanation:

So we already have $55 in our bank account.

And we earn $5 per hour.

In other words, the total amount of money in our account after working x hours is represented by the equation:

[tex]y=5x+55[/tex]

We want to buy a new phone that costs $395. To find out how many hours we need to work, substitute 395 for y. Thus:

[tex]395=5x+55[/tex]

Subtract 55 from both sides:

[tex]340=5x[/tex]

Divide both sides by 5:

[tex]x=68[/tex]

Therefore, we must work for (at least) another 68 hours in order to earn enough money to purchase the phone.

Answer: The real numbers include natural numbers or counting numbers, whole numbers, integers, rational numbers (fractions and repeating or terminating decimals), and irrational numbers. The set of real numbers is all the numbers that have a location on the number line. Integers …, −3, −2, −1, 0, 1, 2, 3, and so on. All whole numbers are integers, so since 0 is a whole number, 0 is also an integer.

Answer:

169 cm^2

Step-by-step explanation:

Right surface (rectangle)

A = LW = 7 cm * 5 cm = 35 cm^2

Left surface (hidden rectangle)

A = LW = 7 cm * 5 cm = 35 cm^2

Bottom surface (hidden rectangle)

A = LW = 9 cm * 5 cm = 45 cm^2

Front face = back face = 2 * triangle

A = 2 * bh/2 = 2 * 9 cm * 6 cm/2 = 54 cm^2

total surface area = 35 cm^2 + 35 cm^2 + 45 cm^2 + 54 cm^2 = 169 cm^2

Answer:

x = 0.2

Step-by-step explanation:

Order of Operations: BPEMDAS

Step 1: Write out equation

3.5 + 1.2(6.3 - 7x) = 9.38

Step 2: Parenthesis (distribute)

3.5 + 7.56 - 8.4x = 9.38

Step 3: Combine like terms (constants)

11.06 - 8.4x = 9.38

Step 4: Subtract 11.06 on both sides

-8.4x = -1.68

Step 5: Divide both sides by -8.4

x = 0.2

Answer: Wrong

Step-by-step explanation:

Continuous means every value is included. Since fractions of people do not exist, it cannot be continuous.

Wen is wrong.

It is given that ; according to Wen a function is continuous because number of people are unlimited.

We have to tell that whether Wen is right or wrong ?

What is a continuous function ?

A continuous function, is a function whose graph is continuous without any breaks or jumps.

We know that ;

A continuous function in calculus is continuous at a point x = a ; if the curve of the function does NOT break at the point x = a.

We can also say that , continuous means every value is included.

Since fractions of people don't exist, i.e., unlimited , So, it cannot be continuous.

Answer:

Step-by-step explanation:

We can form a table for the relation between muffins sold and days of the week given in the graph.

Days                    Muffins sold

Monday                       5

Tuesday                      6

Wednesday                 5

Thursday                     8

Friday                          10

Saturday                      13

Sunday                        15

This data reflects the sales of muffins are increasing continuously in the given week.

Therefore, number of muffins sold are directly proportional to the number of days of the week.

[tex]\huge\boxed{\sf Volume = 384 \ cm^3}[/tex]

Step-by-step explanation:

Slant Height = 10 cm

Base Edge = 12 cm

Finding the Height using Pythagorean Theorem:

[tex]\sf c^2 = a^2 + b^2 \\\\Where \ c = 10\ cm , b = 6\ cm [Half of 12] \ and \ a \ is \ height\\\\10^2 = a^2 + 6^2\\\\100=a^2 +36\\\\100-36 = a^2\\\\64 = a^2\\\\Taking \ sqrt \ on \ both \ sides\\\\Height= 8 \ cm[/tex]

Now, Finding the volume:

[tex]\sf Volume = a^2 \frac{h}{3}\\\\ Where \ a \ is base \ edge \ and \ h \ is \ height\\\\Volume = (12)^2 \frac{8}{3} \\\\Volume = 144 \frac{8}{3} \\\\Volume = 48*8\\\\\bold{Volume = 384 \ c m^3}[/tex]

To make the equation go through (0,-4) the new equation would be 9x + 5y = 20. We needed to change it from subtracting to adding so the direction of the line would go from going down to up too up to down. In slope-intercept form the original equation would be found by the following.

9x - 6y = 20

-6y = 20 - 9x

y = -20/6 - (-9/6x)

y = 9/6x - 20/6

y = 3/2x - 10/3

To make the perpendicular line, take the slope and apply the opposite and reciprocal.

y = -2/3x - 10/3
