Answer 1

Answer:

Step-by-step explanation:

The first one (0,7) tells you that when x isn't there, the amount of money is 7.

That means that the y intercept is 7.

When x = 1 the total is 15

Money saved = ax + 7

15 = a*1 + 7 Subtract 7

15-7 = a + 7-7

a = 8

The equation is f(x) = 8x + 7

Answer:a 750g bag is better.

Step-by-step explanation: 3 bags would be more G the 2kg and less money 0.23/100 grams 700 g would be 1.4$ for that so 750 g is the best.

Answer:

750 grams at $1.39

Step-by-step explanation:

To make it easy to see, determine how much each option costs per gram.

750 grams cost 1.39. Divide 1.39 by 750 which gives you 0.001853

2 kg is 2000 grams costing 3.99. Divide 3.99 by 2000 which give you 0.001995

100 grams cost $0.23. Divide 0.23 by 100 which gives you 0.0023

So the 750 grams is the best price.

First, notice that (a + 1/a)2 = 42 = 16. But also, (a + 1/a)2 = a2 + 2a(1/a) + 1/a2 = a2 + 2 + 1/a2 = a2 + 1/a2 + 2

So a2 + 1/a2 + 2 = 16, so a2 + 1/a2 = 14.

Now, do that again...

(a2 + 1/a2)2 = 142 = 196, but also (a2 + 1/a2)2 = a4 + 2(a2)(1/a2) + 1/a4 = a4 + 2 + 1/a4 = a4 + 1/a4 + 2

So a4 + 1/a4 + 2 = 196, so a4 + 1/a4 = 194

You can see the pattern... E.g., a8 + 1/a8 = 1942 - 2, etc.

Pass through (-6,-6) parallel to y= 4/3x+8

Answers

Answer:

Step-by-step explanation:

The equation of the line is y = ( 4/3 )x + 2.

What is an equation of a line?

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

Given that the equation is parallel the line y = ( 4 / 3 )x + 8 and passes through the point ( -6 , -6 ).

The general equation of the line is

y = mx + c

The slope of the required line will be the same as the slope of the line parallel to the required line.

m = ( 4 / 3 )

The equation of the line will be written:-

y = mx + c

y = ( 4 / 3 )x + c

-6 = ( 4 / 3 ) x -6 + c

c = 2

y = ( 4/3 )x + 2

Therefore, the equation of the line is y = ( 4/3 )x + 2.

what tis -2(x-6) + 7= 35
. Im am very need of help.
ten points

Answers

You weren't clear with your question, but I am assuming you want to solve for the variable "x."

-2(x - 6) + 7 = 35

-2x + 12 + 7 = 35; distribute the -2

-2x + 19 = 35

-2x = 16; isolate the x variable (the variable you want to solve)

x = -8; divide by -2 to isolate the x variable

Answer:

[tex]x=-8[/tex]

Step-by-step explanation:

1) Distribute

[tex]-2(x-6)+7=35\\-2x+12+7=35[/tex]

2) Add the numbers

[tex]-2x+12+7=35\\-2x+19=35[/tex]

3) Subtract 19 from both sides of the equation

[tex]-2x+19=35\\-2x+19-19=35-19[/tex]

4) Simplify

A. Subtract the numbers

[tex]-2x+19-19=35-19\\-2x=35-19[/tex]

B. Subtract the numbers

[tex]-2x=35-19\\-2x=16[/tex]

5) Divide both sides of the equation by the same term

[tex]-2x=16 \\\frac{-2x}{-2} =\frac{16}{-2}[/tex]

6) Simplify

A. Cancel terms that are in both the numerator and denominator

[tex]\frac{-2x}{-2} =\frac{16}{-2}[/tex]

B. Divide the numbers

[tex]x=-8[/tex]
