What is x?

x/y= 8/y - 1/y

Answer:

i think the answer is b

because,

if x+22=90

x=90-22=68

we know that the sum of the three angles of a triangle is 180

so, that means

90+22+68 should be 180

and it is 180, so the answer must be b

Answer:

x = -2 or -12

The perimeter of the rectangle is got increased by a factor of 2. The correct option is A.

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In rectangle opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at mid-point.

Given

A rectangle has a width of 12.5 m and a length of 105 m.

We know the perimeter of the rectangle is given by

Perimeter = 2 (Lenght + Width)

Let x be the length and y be the width. Then

Perimeter = 2 (x + y)

If the dimensions are multiplied by 2. Then the effect on the perimeter will be

Perimeter = 2 (2x + 2y)

Perimeter = 2 [2 (x + y)]

The perimeter is increased by a factor of 2.

Thus, option A is correct.

Answer: x=4 and y=1

Step-by-step explanation:

From the first equation, we get y = 9 - 2x. Substitute this into the second equation we get

3x - 4(9 - 2x) = 8

3x - 36 + 8x = 8

11x = 44

x = 4

y = 9 - 2(4)

y = 1

1. Observe problem

1-(1/8+1/12+1/2)

Make all common denominator

The Least common multiple of 8,12, and 2 is 24

1-((3+2+12)/24)=

1-17/24=

7/24

Therefore, 28 years make up 7/24 of his life.

Simplifying, he grows 4 years for every 1/24 of his life

200 divided by 30,000 equals

"0.00666666666"

hope this helps!

Answer: 0.006666667 = 1/150

Step-by-step explanation: Reduce the fraction 200/30,000 to lowest terms by extracting and canceling out 200.

The solution is,  the slope of the line that passes through G(−3, 2) and

H(7, 2) is 0.

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

here, we have,

given that,

G(−3, 2) and H(7, 2).

now, we have to find, the slope of the line that passes through G(−3, 2) and H(7, 2).

now, we know that,

Slope = (y2-y1) / (x2-x1)

here,

G(-3,2) = (x1,y1)

H(7,2) = (x2,y2)

Substitute these values to find the slope.

Slope = (2-2)/(7-(-3))

          = 0/10

          = 0

Hence, The solution is,  the slope of the line that passes through G(−3, 2) and  H(7, 2) is 0.

Answer:

It is a linear function because there is a constant rate of change in both the input and output values

Step-by-step explanation:

To determine if the function is linear, calculate the differences between the y values.

If the differences are constant, or the same value, the equation is linear and has a constant slope. If the differences are not the same, the equation is not linear.

difference between y values (output)

7 - 4 = 3

3 - 1 = 3

1 - -2 = 3

⇒ the function is linear

difference between x values (input)

-2 - -5 = 3

-5 - -8 = 3

-8 - -11 = 3

⇒ the function is linear as there is a constant rate of change in both the input and output values

Answer:

[C] 29 Miles

Step-by-step explanation:

Given that the vessel sails 41 miles S 45° E.

We need to determine the how far south the vessel has sailed.

Let us use the Pythagorean theorem to find the distance of the vessel has sailed.

Thus, we have,

[tex]Cos 0= \frac{adj}{hyp}[/tex]

Substituting [tex]0 = 45[/tex]° , [tex]adj = x[/tex], and [tex]hyp = 41[/tex]

Hence, we get,

[tex]cos[/tex] [tex]45 = \frac{x}{41}[/tex]

Simplifying, we have,

[tex]0.71 = \frac{x}{41}[/tex]

Multiplying both sides by 41, we have,

[tex]29.11 = x[/tex]

Rounding off to the nearest integer, we have,

[tex]29 = x[/tex]

Thus, the vessel has sailed 29 miles South.

Therefore, Option C is the correct answer.

[RevyBreeze]

Answer:

y = x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = 1 , then

y = x + c ← is the partial equation

To find c substitute (- 8, - 7 ) into the partial equation

- 7 = - 8 + c ⇒ c = - 7 + 8 = 1

y = x + 1 ← equation of line
