Solve 4^3x=8 by graphing

1 answer:

5 0

Y = mx + b

mx is the slope, with m being the actual slope and x being there to signify that that is the slope. b is the y-intercept. 
-- 
y = 4/3x + 8 

In this case, 8 is the y-intercept. Plot a point at (0,8). 

4/3 is the slope. After you plotted the y-intercept, go up 4 spaces, then go to the right 3 spaces. 

Then draw a line connecting the dots.

Answer:

Step-by-step explanation:

You know that the length of the lines are equal, therefore the value of the angles should also be equal.

Think of it this way:

The greater the angle, the greater the line and vice versa.

Hope this helps.

Answer:

l = 2.25 cm

Step-by-step explanation:

given l is inversely proportional to w² then the equation relating them is

l = $\frac{k}{w^2}$ ← k is the constant of proportion

(i)

to find k use the condition w = 1.5 , l = 16 , then

16 = $\frac{k}{1.5^2}$ = $\frac{k}{2.25}$ ( multiply both sides by 2.25 )

36 = k

l = $\frac{36}{w^2}$ ← equation of proportion

(ii)

when w = 4 , then

l = $\frac{36}{4^2}$ = $\frac{36}{16}$ = 2.25 cm

A skateboarding park charges $7 per session to skate and $4 per session to rent safety equipment. Your friend rents safety equip

beks73 [17]

He spent $36 on safety equipment.
The total cost each time was $11, meaning he had to pay 9 times for each skate session. 4x9=36! ( 7x9= 63 so if you add 36 you'll get 99 just as a way of checking)

love history [14]

Answer:

4 feet by 3 feet

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

Please have a look at the attached photo.

My answer:

width-to -height ratio of 16:9

Let analyse all possible answers:

4 feet by 3 feet

16 divided by 4 is the same as 9 divided by 3 => it is true

28 inches by 21 inches

16 divided by 28 is different as 9 divided by 21 => it is wrong

48 centimeters by 27 centimeters

16 divided by 48 is different as 9 divided by 27 => it is wrong

26 inches by 19 inches

16 divided by 26 is different as 9 divided by 219=> it is wrong

We choose A.

Hope it will find you well.
