A swimming pool is 12 metres long. how many metres would you swim if you swam 8 lengths. ​

Answers

Answer 1
Answer:

Answer:

96m

Step-by-step explanation:

12m * 8 = 96m

unless lengths are counted as to one side and back then it would be double 96

Answer 2
Answer: You would do 12 times by the amount of lengths which is 8 and the answer would be 12 times 8= 96

Answers

Answer:

D

Step-by-step explanation:

If we look at the right side of the equation we see that the y-intercept is 2, so we will place a point on (0,2).

Next, we look to see if the slope of the graph if positive or negetive, and to see what is the slope (2x).

Finally, we look at the inequality if it is greater than (>), less than (<), greater than or equal to (_>), or less than or equal to (<_).

*Note the following:

if < then the line is dotted and the shading will be under the line.

if > then the line is dotted and the shading will be above the line.

if <_ then the line is solid and the shading will be under the line.

if _> then the line is solid and the shading will be above the line.*

It is a lot of information if you look at it, but with practice it can be made easier.

Can someone help me for this

solve for invers
switch x and y and solve for y
y=2x+5
x=2y+5
x-5=2y
(x-5)/2=y

y=(x-5)/2

it is a function is true

it is true that is the reflecttion of y=2x+5, but not y=2x so don't select this option

slope is 1/2, true

slope is defined, so it is false

y intercept s where x=0
y=(0-5)/2=-5/2
true

36 is 0.9% of what number w?

Answers

We set up an equation: 36/?= 0.9/100

Cross multiply: 0.9*?= 36*100
⇒ ?= 36*100/0.9= 4000

36 is 0.9% of 4000.
36 x 0.9 = answer

what is the equation, in slope- intercept form, of the line that contains the points (-3,4) and (5,7)

Answers

Answer:

y = (3)/(8) x + (41)/(8)

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 the slope use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 3, 4) and (x₂, y₂ ) = (5, 7)

m = (7-4)/(5+3) = (3)/(8), hence

y = (3)/(8) x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

using (5, 7 ), then

7 = (15)/(8) + c ⇒ c = 7 - (15)/(8) = (41)/(8)

y = (3)/(8) x + (41)/(8) ← equation in slope-intercept form
