Step-by-step explanation:

The total money would Gavin have after 10 weeks of savings is $ 170 and the required expression is 100 + 7w  

A mathematical expression is a combination of numbers, symbols, and operators that represents a mathematical relationship or calculation. It is written in a way that follows specific rules of mathematical notation, such as using parentheses to indicate the order of operations.

Here we have

Gavin is saving up to buy a new phone.

He already has $100 and can save an additional $7 per week using money from his after-school job

Let us assume that he worked for 'w' weeks  

The amount earned for 'w' weeks = 100 + 7w

Hence, the required expression is 100 + 7w  

The total amount saved in 10 weeks = 100 + 7(10) = $ 170

Therefore,

The total money would Gavin have after 10 weeks of savings is $ 170 and the required expression is 100 + 7w

Answer:

The slope is 3 and the y-intercept is 7. The equation of the line is 3y - 7.

Step-by-step explanation:

The equation of the line works such that y = mx + b where m is the slope and b is the y-intercept. Thus,

slope = m

         = 3

y-intercept  = b

                   = 7

B.) 1 and 3; 2 and 4 in the picture are not supplementary.

Supplementary angles refers to the type of angles whose sum is 180°. It is not mandatory for the division of angle to be in half. The angles can be 60° and 120°, 130° and 50°, 90° and 90° and so on.

In the figure, we can see two lines intersect each other. Angle 1 and 2 are present on straight line, and hence, their sum will be 180°. Angle 2 and 3 are present on straight line, and hence, their sum will be 180°. Angle 3 and 4 are present on straight line, and hence, their sum will be 180°. Angle 1 and 4 are present on straight line, and hence, their sum will be 180°.

Angle 2 and 3 and angle 1 and 4 are opposite angles, that are not present on same straight line. Therefore, they are not supplementary angles.

Answer: x = 29

Step-by-step explanation:

The four angles of a Parallelogram equal to 360. Its name is derived from the fact that its made up of two sets of parallel lines which means that its opposite angles are equivalent. Fortunately, you are given the values for the angles that are not equivalent which means you can create an equation and solve for x.

5x - 23 + 5x - 23 + 2x + 2x = 360

14x - 46 = 360

14x = 406

A percentage is a way to describe a part of a whole. The cost of the car is $12,412.

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Given that Wayne's country has a sales tax rate of 5%. The total cost of the car plus tax is $13,032.60. Therefore, the total cost of the car can be written as,

The total cost of the car = Cost of the car + Tax on the car

$13,032.60 = Cost of the car + 5% of the cost of the car

Let the cost of the car be represented by x.

$13,032.60 = x + 5% of the x

$13,032.60 = x + 0.05

$13,032.60 = 1.05x

x = $13,032.60 / 1.05

x = $12,412

Hence, the cost of the car is $12,412.

Answer:

Given a function y=f(x) its first derivative – the rate of change of y with respect to x – is defined by: dydx=limh→0[f(x+h)−f(x)h]. Finding the derivative of a function by computing this limit is known as differentiation from first principles

and put the formula answer will be there

Answer:

see explanation

Step-by-step explanation:

Given f(x) then the derivative f'(x) is

f'(x) = lim( h tends to 0 ) [tex]\frac{f(x+h)-f(x)}{h}[/tex]

      = lim( h to 0 ) [tex]\frac{\frac{3}{x+h}-\frac{3}{x} }{h}[/tex]

     = lim( h to 0 ) [tex]\frac{3x-3(x+h)}{hx(x+h)}[/tex]

     = ( lim h to 0 ) [tex]\frac{3x-3x-3h}{hx(x+h)}[/tex]

     = lim( h to 0 ) [tex]\frac{-3h}{hx(x+h)}[/tex] ← cancel h on numerator/ denominator

     = lim( h to 0 ) [tex]\frac{-3}{x(x+h)}[/tex] ← let h go to zero, then
