Xxx yyy -12−12minus, 12 141414 -2−2minus, 2 212121 888 282828 What is the xxx-intercept of the line?

Answers

Answer:

-12

Step-by-step explanation:

Let the equation of the line be x = y - 12

The x intercept occurs at y = 0

Substitute y = 0 into the equation

x = 0 -12

x = -12

Hence the x intercept of the line is -12

Note that the equation was assumed. The same calculation can be employed for any equation given

Find the solution of the system of equations -7x-3y=-20 3x+6y=-15

Answers

9514 1404 393

Answer:

(5, -5)

Step-by-step explanation:

I like a graphing calculator for quickly finding a solution to a system of equations. It shows the solution to be (5, -5).

We can add the second equation to 2 times the first to eliminate the y-variable.

2(-7x -3y) +(3x +6y) = 2(-20) +(-15)

-11x = -55 . . . . . collect terms

x = 5 . . . . . . . . . divide by -11

Substituting this value into the second equation, we have ...

3(5) +6y = -15

6y = -30 . . . . . . . . subtract 15

y = -5 . . . . . . . . . . divide by 6

The solution is (x, y) = (5, -5).

Jo sold 132 mugs. One quarter of the mugs were small. The rest were large. How many small mugs did Jo sell? * 1 point

Answers

Answer:

33 small mugs

Step-by-step explanation:

Given:

Total number of mugs sold by Jo = 132

One quarter of the mugs were small. The rest were large.

To find: Number of small mugs sold by Jo

Solution:

Number of small mugs sold by Jo = [tex]\frac{1}{4}[/tex] (Total number of mugs sold by Jo)

Therefore,

Number of small mugs sold by Jo [tex]=\frac{1}{4}(132)=33[/tex]

The angle of a triangle are in the ratio 3:7:8. Find the angles.

Answers

Answer:

30°, 70°, 80°

Step-by-step explanation:

Let the measures of the angles be 3x, 7x and 8x.

Since, sum of the measures of all the three angles of a triangle is 180°.

Therefore,.

3x + 7x + 8x = 180°

18x = 180°

x = 180°/18

x = 10°

3x = 3*10° = 30°

7x = 7*10° = 70°

8x = 8*10° = 80°

Thus, the measures of the angles are 30°, 70°, 80°.

It took the football team 5 h to travel from Titletown, a total distance of 1320 km. Part of the trip was by bus and the remainder by plane. The bus averaged 40 km/h and the plane 600 km/h. How many hours were spent travelling by bus?

Answers

Answer:

It took 2 hours by plane

Step-by-step explanation:

let bus is represented by x and plane is represented by y

the total distance of bus and plane will be represented by equation:

40 x + 600 y = 1320 (1)

the total time taken by bus and plane will be represented by:

x + y = 5 (2)

solving equations (1) and (2) simultaneously:

Multiply by 40 on both sides in eq (2) and then subtract (1) and (2)

40 x + 600 y = 1320

40 x + 40 y = 200

_______________

560 y = 1120

y = 1120/ 56

y= 2

since plane is represented by y so, the time they spent travelling by plane is 2 hours.

D) the winning time increased by an average of 0.267 second per year from year 2 to year 4.

Answers

Answer:

The winning time increased by an average of 0.4 second per year from year 2 to year 4.

Step-by-step explanation:

I just took the quiz

The winning time for a race displayed in the table would be:

A). The winning time increased by an average of 0.4 seconds per year from year 2 to year 4.

Find the increase in winning time:

Given that,

Year Winning Time(seconds)

1 27.5

2 28.4

3 28.7

4 29.2

5 29.44

The total change in the time = (0. + 0.3 + 0.5 + 0.24)/4

= 0.485 seconds

If we round off, it becomes 0.5 seconds.

Therefore, it can be considered that an average of 0.5 seconds changes every year from year 2 to 4.

Thus, option A is the correct answer.
