7x-3y=21 Find the intercept

Mathematics
1 answer:
Cerrena [4.2K]2 years ago

Y-intercept:

Plug in 0 for 'x' to find the y-intercept:

7x - 3y = 21

7(0) - 3y = 21

0 - 3y = 21

-3y = 21

Divide -3 to both sides:

y = -7

So the y-intercept is -7.

x-intercept:

7x - 3y = 21

Plug in 0 for 'y' to find the x-intercept.

7x - 3(0) = 21

7x - 0 = 21

7x = 21

Divide 7 to both sides:

x = 3

So the x-intercept is 3.

3(6d-24)=6(12+3d)<br> i need help
Alexxandr [17]

Answer:

No solutions

Step-by-step explanation:

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

3(6d−24)=6(12+3d)

Step 1: Simplify both sides of the equation.

3(6d−24)=6(12+3d)

(3)(6d)+(3)(−24)=(6)(12)+(6)(3d)(Distribute)

18d+−72=72+18d

18d−72=18d+72

Step 2: Subtract 18d from both sides.

18d−72−18d=18d+72−18d

−72=72

Step 3: Add 72 to both sides.

−72+72=72+72

0=144

Answer:

There are no solutions.

A survey asked people of different ages whether they get their news by reading the paper. What is the probability that a person
Bingel [31]

C. 60%

The probability that a person surveyed is 40 or older and gets the news by reading the paper is 60%.

Step-by-step explanation:

In our case, we have to find the probability of a person getting their news by reading the paper. But we are given with a condition that the person must be 40 or older.

The survey is conducted among 80 people.

Number of people aged 40 or older = 40

No of people aged 40 or older and read paper = 24

Probability formula is the ratio of number of favorable outcomes to the total number of possible outcomes.

Probability of a person aged 40 or older reads a paper =

(No. of People aged 40 or older and read paper)/(No. of people aged 40 or older)

= 24/40

= 0.6

= 60%
