(0,0), what is the x-coordinate of E'?
Please help 20 points

Answer:

x=142, y=-360. (142, -360).

Step-by-step explanation:

5x+2y=-10

3x+y=66

----------------

5x+2y=-10

-2(3x+y)=-2*66

-----------------------

5x+2y=-10

-6x-2y=-132

-------------------

-x=-142

x=142

3(142)+y=66

426+y=66

y=66-426

y=-360

Answer:

1- 5x+2y+−2y=−10+−2y

5x=−2y−10

[tex]\frac{5}{5}[/tex]= [tex]\frac{-2y-10}{5}[/tex]

x= [tex]\frac{-2}{5}y-2[/tex]

2-  3x+y+−y=66+−y

3x=−y+66

[tex]\frac{3x}{3} = \frac{-y+66}{3}[/tex]

[tex]x=\frac{-1}{3}y+22[/tex]

Step-by-step explanation:

Answer:

-119

Step-by-step explanation:

Substitute a for 2.7 since a = 2.7

Then multiply -20 by 2.7 = -54

Next subtract -54 by 65

Finally, you have your answer!

Answer: 1

Step-by-step explanation:

4m + 8 = 12

=> 4m = 4

=> m = 1

Answer:

Subtract 8 from both sides now your left with 4m and 4. Divide 4 from both sides to get 1. 1 is your answer

Answer:

sine D = 0.9459

sine E = 0.3243

Step-by-step explanation:

Mathematically, sine is the ratio of the opposite to the hypotenuse

The hypotenuse is the longest side and we have it as 37 in the diagram given

the opposite to angle E is 12

So the sine of E = 12/37 = 0.3243

For D , its opposite is 35

The sine of D = 35/37

sine of D = 0.9459

Answer: Percent" or "%" means "out of 100" or "per 100", Therefore 7% can be written as 7100 . Because 7 is a prime number and cannot be factored this is the simplest form.

Answer:

19 feet

Step-by-step explanation:

first, identify which is length and which is width. length is always longer than the width.

in order to do so, we need the measures in the same units, so let's convert . 12 yards to feet and 204 inches to feet:

there are 3 feed in a yard, so let's multiply 12 by 3:

12 • 3 = 36 feet

there are 12 inches in 1 foot, so let's divide 204 by 12

204 ÷ 12 = 17 feet

which is longer? 36 feet! so that's the length

finally, subtract the width(17 ft) from the length (36 ft)

36 - 17 = 19ft

Answer:

In a graph, the x-intercept will be the point in which the line crosses the horizontal line of the plane.

The y-intercept is found when the line crosses the vertical line of the plane.

In an equation, y = mx + b, the y-intercept is the value of b, and the x-intercept is shown when y = 0. (substitute y for 0 and find the value of x)

Answer:

2

Step-by-step explanation:

(4 - 5) - (13 - 18 + 2)

According to PEMDAS, we should simplify the parentheses first.

= (-1) - (-3)

When you subtract a negative number, you are actually adding.

= -1 + 3

Now, add.

= 2

Answer: 15

Step-by-step explanation:

Lets name the missing point as "x"

8^2 + x^2 = 17^2

=> 64 + x^2 = 289

=> x^2 = 289 - 64

=> x^2 = 225

=> x = 15

Answer:

0.07 (7/100) is closer to 0.

1.150 (1150/1000) is closer to 1.

0.391 (391/1000) is closer to 1/2.

0.0999 (999/10,000) is closer to 0.

0.99 (99/100) is closer to 1.

0.599 (599/1000) is closer to 1/2.

Put everything as a fraction. The first spot after the decimal means you put the number over 10, the second place means you put it over 100, the third 1,000, fourth 10,000 and so on. Hope I helped! ^^Step-by-step explanation:

The closeness of the given function is found to be by writing it in the simplest form as 1.

A fraction is a number written in the form a / b, where a and b are integers and b ≠ 0.

The number a is called as the numerator and b is the denominator.

The given fraction is 15/20.

It can be simplified as below,

Divide numerator and denominator by the common factor 5 as,

(15 ÷ 5)/(20 ÷ 5)

⇒ 3/4

The given fraction 3/4 is greater than zero and closest to 1.

Hence, the given fraction is closest to integer 1.

Answer: 260 minutes.

Step-by-step explanation:

This represents the ratio between the minutes he reads and the pages he reads: 40 : 52

The book Miguel is reading is 338 pages long. Miguel also reads 52 pages in 40 minutes. You can divide 338 by 52, which is equal to 6.5.

If it takes Miguel 40 minutes to read 52 pages, then we can multiply that by 6.5. 40 x 6.5 = 260.

In conclusion, it will take Miguel 260 minutes to read the entire book, or 4 hours and 20 minutes.
