(i) Not true for any cases, (ii) True for some cases, (iii) True for some cases, (iv) True for all cases.

Step-by-step explanation:

Now we proceed to check each statement in terms of concepts of function from Analytical Geometry:

(i) Two lines that have the same y-intercept and the same slope intersect at exactly one point.

False, two lines that have the same y-intercept and the same slope intersect at every point. Both lines are coincident. (Answer: Not true for any cases)

(ii) Two lines that have the same y-intercept intersect at exactly one point.

Conditionally true, two lines that have the same y-intercept intersect at exactly one point if and only if slopes are different. (Answer: True for some cases)

(iii) Two lines that have the same slope do not intersect at any point.

Conditionally true, two lines that have the same slope do not intersect at any point if and only if they share the same y-intercept. (Answer: True for some cases)

(iv) Two lines that have two different slopes intersects at exactly one point.

True, two lines that have two different slopes intersects at exactly one point no matter what y-intercepts they have. (Answer: True for all cases)

Answer:

i hope this helps

Step-by-step explanation:

3% is the interest rate. Using the formula I=PRT, you can simply derive the rate by putting the given numbers in.

I = 450P = 3,000R = ?T = 5 Years

The equation now goes,450 = 3,000 * R * 5450 = 15,000 * R450/15,000 = R0.03 = R

multiply it by 100,

R = 3%

First begin with the interest formula.

Interest = Principal x Rate x Time

The $250 is the principal is the amount of money invested.

The rate is 4% which translates to the decimal .04.

The time is 5 years.

So we have I = (250)(.04)(2).

Multiplying, (25)(.04) is 10 and we have 10(2) which is 20.

This means that the interest earned in 2 years is $20.

Answer:

y=1

Step-by-step explanation:

Let's solve your equation step by step.

Step 1: Simplify both sides of the equation.

−4(2y−4)−4y=4

(−4)(2y)+(−4)(−4)+−4y=4(Distribute)

−8y+16+−4y=4

(−8y+−4y)+(16)=4(Combine Like Terms)

−12y+16=4

−12y+16=4

Step 2: Subtract 16 from both sides.

−12y+16−16=4−16

−12y=−12

Step 3: Divide both sides by -12.

y=1

Answer:

x = 4

Step-by-step explanation:

3x + 2y = 26

y = x + 3

Plug in the equation for y

3x + 2(x + 3) = 26

Multiply the 2 with what is in the parantheses

3x + 2x + 6 = 26

Combine like terms and solve for x

5x + 6 = 26

5x = 20

x = 4

Answer

x=4, Y=7

Step-by-step explanation:

3x + 2y = 26

Y=x + 3

3x+2(x+3)=26

3x+2x+6=26

5x=20

x=4

Y=4+3

Y=7

Check

3(4)+2(7)=26

12+14=26

26=26

Answer:

12 ≤ x

Explanation:

Kids 12 and under, meaning that the age of someone who enters the restaurant has to be less than or equal to 12 to eat free

The inequality which represents the age of the people who do not get the discount is x > 12.

Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.

Given that,

Children 12 and under eat free at a local restaurant.

Let x represents the age of the people.

Since the children who are 12 and under will get the discount, the age of the people who do not get the discount is the people with age greater than 12.

That is the inequality representing this situation is,

x > 12

Hence the required inequality is x > 12.
