1) slope and y-intercept from tables

Answer:

Q1.Let's solve your equation step-by-step.

2(x+3)=5x+6−3x

Step 1: Simplify both sides of the equation.

2(x+3)=5x+6−3x

(2)(x)+(2)(3)=5x+6+−3x(Distribute)

2x+6=5x+6+−3x

2x+6=(5x+−3x)+(6)(Combine Like Terms)

2x+6=2x+6

2x+6=2x+6

Step 2: Subtract 2x from both sides.

2x+6−2x=2x+6−2x

6=6

Step 3: Subtract 6 from both sides.

6−6=6−6

0=0

Answer:

All real numbers are solutions.

Q2.x−3=2x−3−x

Step 1: Simplify both sides of the equation.

x−3=2x−3−x

x+−3=2x+−3+−x

x−3=(2x+−x)+(−3)(Combine Like Terms)

x−3=x+−3

x−3=x−3

Step 2: Subtract x from both sides.

x−3−x=x−3−x

−3=−3

Step 3: Add 3 to both sides.

−3+3=−3+3

0=0

Answer:

All real numbers are solutions.

Start with your $22.50 subtotal (cost without tax)

Then, solve for 6.5% of $22.50

Set your equation up like so: 6.5/100=x/22.50

Cross multiply then you should have 100x=146.25

Solve to get 1.4625% (If you need it rounded, it's 1.5%)

1.5% ----> $1.46

$22.50+$1.56=$23.96

She spent $23.96

I'm pretty sure the answer's $1.46.

($1.46 is the amount of tax, not the total)

The solutions of the equation y = 11x are;

⇒ (3, 33)

⇒ (-17, -187)

⇒ (3/11, 3)

What is Equation of line?

The equation of line passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;

y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The equation is,

y = 11x

Now,

The solutions of the equation is always satisfy the equation of line.

So, we check all the points as;

First point (x , y) = (- 9, 99)

Substitute in the equation, we get;

y = 11x

99 = 11 x - 9

99 ≠ - 99

Thus, This is not a solution.

Second point (x , y) = (11, 144)

Substitute in the equation, we get;

y = 11x

144 = 11 x 11

14 ≠ 121

Thus, This is not a solution.

Third point (x , y) = (3, 33)

Substitute in the equation, we get;

y = 11x

33 = 11 x 3

33 = 33

Thus, This is a solution.

Fourth point (x , y) = (- 17, - 187)

Substitute in the equation, we get;

y = 11x

- 187 = 11 x - 17

- 187 = - 187

Thus, This is a solution.

Fifth point (x , y) = (3/11, 3)

Substitute in the equation, we get;

y = 11x

3 = 11 x 3/11

3 = 3

Thus, This is a solution.

Therefore, The solutions of the equation y = 11x are;

⇒ (3, 33)

⇒ (-17, -187)

⇒ (3/11, 3)

Answer:

280$ per year

Step-by-step explanation:

The interest earn by Marsha is $280 a year and interest = $280x for x years.

Simple interest is a quick and simple approach to figure out how much money has accrued interest. Interest is always applied to the original principal amount and is calculated at the same rate for each period of time. Any bank where we deposit money will pay us interest on that amount.

Given amount deposited = principal = $7,000

rate = 4%

simple interest = PRT/100

where p = principal, T = time, R = Rate

Interest for 1 year  = PRT/100 = (7000 x 4 x 1)/100

Interest for 1 year  = 28000/100

Interest for 1 year = $280

and interest for x years =  $280x

Hence $280x is interest for x years.

I am not sure if this is exactly how you do it.

Answer:

Sorry if I'm wrong but...…..

I think the first one is an equation and it's a fraction with powers. (4 and 5).

The next one is a fraction and it is to the power of the number above you have to figure out if you have to multiply the powers with the number under it add them and divide or multiply them by the other number.

The third one is a multiplication problem you have to figure out what "r" is to figure it out you have to do 6 to the 2nd power to get r and you have to do 2 to the 6th power to get the other r. Then multiply the numbers together tp get the answer.
