which pints are solutions tot he equation y=11x?
select all that apply
(-9,99)
(11,144)
(3,33)
(-17,-187)
(3/11,3)
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)

1. 2(x+3)=5x+6−3x
2. x−3=2x−3−x
3. 3(x−5)=2(x−5)+x
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

All real numbers are solutions.

Esther is participating in a walk-a-thon. She will raise 5 dollars for her charity for each lap she walks.
Let l = the number of laps she walks
Let d = the number of dollars she raises
independent variable = number of dollars; dependent variable = number of laps
independent variable = number of charities; dependent variable = number of people
independent variable = number of dollars; dependent variable = number of people
independent variable = number of laps; dependent variable = number of dollars
Answer: independent variable = number of laps; dependent variable = number of dollars
Step-by-step explanation:
The number of laps walked isn't influenced by anything so it is the independent variable while the number of dollars is influenced by the number of laps making it the dependent variable.
Marsha deposited $7,000 into a savings account years ago. The simple interest rate is 4%. How much money did Marsha earn in interest?
interest= $___ · ___ · ___x years.
Answer:
280$ per year
Step-by-step explanation:
The interest earn by Marsha is $280 a year and interest = $280x for x years.
What is Simple Interest?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.
