A square has a side length of 4\19x - 9 units. what is its perimeter in terms of x?a) 4\19x - 36

b) 16\19x-9

c) 16\19x-36

d) 16\19x +36

Answers

16/19 x-36 is the perimeter of square whose side length is 4\19x - 9 units

What is Square?

square, in geometry, a plane figure with four equal sides and four right (90°) angles. A square is a special kind of rectangle (an equilateral one) and a special kind of parallelogram

We need to find the perimeter of square whose side length is 4\19x - 9 units.

Perimeter of square=4a

Where a is length of side

a=4\19x - 9

Perimeter of square=4(4\19x - 9)

Apply distributive property

=16/19 x-36

Hence 16/19 x-36 is the perimeter of square whose side length is 4\19x - 9 units

The answer is c because you add 4/19x four time because it is a square. That will be 16/19x. Then you add -9 four time for the same reason and end up with -36.

the ratio of blue marbles to red marbles in a bag is 11:9.If there are 99 blue marbles in the bag,how many red marbles are there?

Answers

Let the number of red marbles be x.

We have: 99/x = 11/9

Cross multiply:
11x = 99*9
⇒ x= (99*9/11)= 81

There are 81 red marbles~

What graph best represents y=2^x + 1

Answers

Answer:

The graph that best represents the given equation in the attached figure

Step-by-step explanation:

we have

$y=2^x+1$

Find the y-intercept

Remember that the y-intercept is the value of y when the value of x is equal to zero

For x=0

substitute

$y=2^0+1=2$

The y-intercept is the point (0,2)

The given function is increasing, because the y-value increases as the x-value increases. The function tends to go up as it goes along

therefore

The graph that best represents the given equation in the attached figure

Passing through (-2, -9) and (6, 7) write in slope intercept form

Answers

Answer:

y = 2x - 5

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 )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 2, - 9) and (x₂, y₂ ) = (6, 7)

m = (7 + 9) / (6 + 2) = 16/8 = 2

y = 2x + c ← is the partial equation

to find c use either of the 2 points

using (6, 7), then

7 = 12 + c ⇒ c = 7 - 12 = - 5

y = 2x - 5 ← equation in slope-intercept form
