Answer: f(4) = 8,                     f(-5) = -19,                 f(2-x) = -3x+2

Step-by-step explanation:

Let's start by analyzing what we are given:

f(x)=3x-4

In this equation, f is the name of the function.

The number in the parentheses represents x.

The 3x-4 tells us what the equation does. In this instance, we multiply x by 3 and then subtract 4.

Let's start with (a).

f(4)

Since we have established that the number in the parentheses is x, we can plug 4 in for x into the equation f. We must abide by the order of operations. Therefore, we can obtain the following:

f(4) = 3(4) -4

f(4) = 12 -4

f(4) = 8

We can continue this for part (b).

f(-5) = 3(-5) -4

f(-5) = -15-4

f(-5) = -19

Part (c) is slightly different, but applies the same principles we established previously. On this part, we must recall the distributive property. The 3 multiples the 2 and the x. We must also remember to combine like terms.

f(2-x) = 3(2-x) -4

f(2-x) = 6 - 3x -4

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

The primary difference between expression and equation has an equal sign. An equation has a left side , a right side and an equal symbol separating the sides. But an expression by contrast does not have any sides and equal symbol.

An expression is a combination of numbers, variables, functions (such as addition, subtraction, multiplication or division etc.) Expressions can be thought of as similar to phrases.

The primary difference between expression and equation is an equal sign. An equation has a left side , a right side and an equal symbol separating the sides. But an expression by contrast does not have any sides and equal symbol.

For example

It should be noted that if your coefficient is a negative number, this indicates for a real life scenario that C. the starting amount is negative.

A negative coefficient indicates that the dependent variable tends to drop as the independent variable rises. The coefficient value is the amount that a one-unit change in the independent variable affects the mean of the dependent variable while keeping all other model variables constant.

If the correlation coefficient is negative, the two parameters you evaluated may have an inverse relationship.

Therefore, it should be noted that if your coefficient is a negative number, this indicates for a real life scenario that the starting amount is negative

The simple interest that Su Young paid for borrowing $2,900 for 15 months at 5.5% per year is $199.375.

Simple interest is interest that is not compounded.

Compounding involves adding earned interests to the principal when computing the next period's interest.

Principal = $2,900

Period = 15 months or 1.25 years

Interest Rate = 5.5%

Simple interest amount = Principal x Period x Rate

= $199.375 ($2,900 x 1.25 x 5.5%)

Thus, based on simple interest, Su Young paid $199.375.

Answer: Change = - 2.8 gallons

Step-by-step explanation:

Let X be the starting amount of paint in the can, in gallons.

"Removes 5/8 gallon" can be written -(5/8)gal

"Adds 3/8 gallon" becomes +(3/8)gal

The result is :  X - (5/8)gal + (3/8)gal = Remaining Paint (gallons)

Consolidating:  Remaining (gallons) = X - (2/8)gal

If we want the overall increase/decrease, subtract the initial volume:

Initial - Remaining = Change in amount of paint in can

Change =  (X-(2/8)gal) - X = - (2/8) gallons

The height of the rectangular pyramid will be 5 centimeters.

The volume of any solid body is defined as the space covered by the object in the three-dimensional space. For a rectangular pyramid, the volume will be the space covered by a pyramid in a three-dimensional space.

Given that the volume of 70 cubic centimeters, length of 7 centimeters, and width of 6 centimeters.

The height of the rectangular pyramid is calculated by using the formula:-

V = ( l w h ) / 3

70 = ( 7 x 6 x h ) / 3

h = 70 / 14

h = 5

The expression as a single logarithm is log (2/3).

In mathematics, the inverse function of an exponent is a logarithm. This means that the logarithm of a fixed number, such as a, at base b, is used to represent the exponent to which the fixed number must be raised in order to create the number x.

The general properties of logarithm for a fixed base are:

Now from the above properties of logarithms we can calculate:

log 8-2 log 6+log 3

=log 8 + log 3 - 2log6

We know that logₐx+logₐy=logₐxy and logₐxⁿ=n logₐx

∴log(8×3) -log(6²)

=log 24 - log 36

Again we know that logₐx-logₐy=logₐ(x/y)

=log(24/36)

=log(2/3)

Therefore the given expression written as a single logarithm is log(2/3).

The measures of the angles are

1. Angle TLN, MZQ and NLM

The angles TLN and NLM are supplementary angles

So, we have

TLN + NLM = 180

This gives

3x - 18 + y = 180

Also, we have

TLN + MZQ = 180

So, we have

3x - 18 + 5x + 14 = 180

Evaluate the like terms

8x -4 = 180

This gives

8x = 184

Divide

x = 23

Substitute x = 23 in 3x - 18 + y = 180

3 x 23 - 18 + y = 180

Evaluate

51 + y = 180

So, we have

y = 129

The above computations imply that:

TLN = 3 x 23- 18 = 51

NLM = y = 129

MZQ = 5 x 23 + 14 = 129

2. Angle JZQ and TLN

The above means that

JZQ = TLN

So, we have

9x + 9 = 8x + 19

Evaluate

x = 10

So, we have

JZQ = TLN = 9 * 10 + 9

JZQ = TLN = 99

3. Angle ZMR, LMO and LMR

The angles ZMR and LMO are congruent angles

So, we have

ZMR = LMO

This gives

x + 14 = 2x - 6

Evaluate

x = 20

Also, we have

LMR + LMO = 180

So, we have

y + 2x - 6 = 180

y + 2 x 10 - 6 = 180

y + 14 = 180

So, we have

y = 166

Step-by-step explanation:

Hey there!

To find the price for 308 bags of chips FOR 308 people, we need to first know what the price for 1 bag is

It says that it is 2 dollars for 5 bags

Now, we need to divide 2 by 5 to see how much money 1 bag is

2/5 is 0.4 and in this case 0.40 since we're dealing with money

Now that we know this, all we need to do is multiply 0.40 by 308 because we are buying for 308 people

0.40 x 308 is 123.2

This means that for 308 people, it would cost $123.20 to supply them all with a bag of chips!
