9 Can Someone Please Explain This

Answers

Answer 1

Answer:

D

Step-by-step explanation:

The vertex of the triangle is adjacent to 90° on a straight line, so

vertex = 180° - 90° = 90°

The triangle has 2 congruent sides and is therefore isosceles with 2 congruent base angles, then

x = [tex]\frac{180-90}{2}[/tex] = [tex]\frac{90}{2}[/tex] = 45° → D

Write an equation that shows the relationship between the number of practices Larry attends, x, and the total number of miles he runs, y.

Y=

Answers

Answer:

8x=y or y=8x

Step-by-step explanation:

So 8 is the number of hours,

we can interpet x for the amount of practice he goes to. For example if hee goes,

for example if he goes to 2 practices the equation will be =

8(2)=Y.... 8(2)=16

16 is the number of miles he runs for 2 practice

We can insert the number of practice he goes to into X

Answer:

Swimming Pool: $5000Caribbean: $15000

Step-by-step explanation:

Let p and c represent the costs (in thousands) of swimming pool and Caribbean weddings, respectively. We have ...

  5p +2c = 55 . . . . . total cost of the weddings

  p = c -10 . . . . . . . . the difference in their cost

Substituting for p in the first equation gives ...

  5(c -10) +2c = 55

  7c -50 = 55

  7c = 105

  c = 15

  p = 15 -10 = 5

The Swimming Pool weddings cost $5000; the Caribbean weddings cost $15,000.

Christian has been offered a new job that pays $24,000 a year plus 3% of sales. For what total sales would this new job pay more than his current job which pays $60,000?

Answers

Answer:

$1,200,000

Step-by-step explanation:

Let x = sales

Since he gets 3% of a sale, we multiply x by 0.03

24,000 + 0.03x = 60,000

Subtract 24,000 from both sides

24,000 + 0.03x = 60,000

- 24,000            - 24,000

0.03x = 36,0000

Divide both sides by 0.03

0.03x/0.03 = 36,0000/0.03

x = 1,200,000

Answer:

29

Step-by-step explanation:

Insert 2 in all the x's so, 2(2)^4+(2)^3-4(2)-3

Answer:

f(2)= 29

Step-by-step explanation:

f(x) = 2x^4 + x^3 - 4x -3

all you need to do is to place "2" anywhere you see x in f(x)

2(2)^4 + (2)^3 + 4(3) - 3

32+ 8 - 8 - 3

1 chain = 66 feet

Length ( l ) = 66 feet

Breadth ( b ) = 10 feet

To find :

The area of a cricket pitch in square feet = ?

The area of a cricket pitch in square feet will be in the shape of rectangle.

660 square feet is the area of a cricket pitch.

Can you find the point-slope equation of the line that is parallel to y = -2x - 3 that passes through (0, 5)?

Answers

Answer:

y= -2x + 5

Step-by-step explanation:

Parallel equations share the same slope so, you need to take the x coordinate and multiply it by the slope which is -2, and you should get 0. To get from 0 to 5 we need to add 5, so 5 is your y-intercept.

Complete the table to find the rule for the reflection, the coordinates of triangle A′B′C′, and the coordinates of the reflected image, triangle A″B″C″.

Answers

When we reflect a point across an axis, the distance between the point and the axis stays the same, but is flipped to the opposite side.  

We know that the coordinates of point A are (4,1), the coordinates of point B are (6,3), and the coordinates of point C are (2,4).  

In this case, Triangle ABC is a reflection of point A'B'C' across the y-axis.
