Answer:

3/4

Step-by-step explanation:

.74(75%) is equal to 75/100

The greatest common factor is 25, so divide 75 by 25 and 100 by 25.

75/25=3 100/25=4

So, 75/100 simplified is 3/4.

Answer:

3/4 is 75% as a fraction

Step-by-step explanation:

Every percent is over 100.

To convert, you would to 75/100 and divide both top and bottom by 5

$\frac{75}{100} / \frac{5}{5}$ and you would get 15/20

You answer would be 15/20 UNLESS its asking you to put it in simplest form.

To put it into simplest form, you would divide both sides by 5 again.

Write an exponential equation in the form y = abx whose graph passes through points (−3, 24) and (−2, 12). y = 3x y = 3(0.5)x y

Bingel [31]

Answer:

Option B.

Step-by-step explanation:

The given exponential equation is

$y=ab^x$ ...(1)

It is given that the graph of above equation passes through points (−3, 24) and (−2, 12).

The graph passes through the point (-3,24), so substitute x=-3 and y=24 in equation (1).

$24=ab^{-3}$ ...(2)

The graph passes through the point (-2,12), so substitute x=-2 and y=12 in equation (1).

$12=ab^{-2}$ ...(3)

Divide equation (3) by equation (2).

$\dfrac{12}{24}=\dfrac{ab^{-2}}{ab^{-3}}$

$0.5=b$

Substitute b=0.5 in equation (2).

$24=a(0.5)^{-3}$

$24=\dfrac{a}{(0.5)^{3}}$

$24=\dfrac{a}{0.125}$

$24\times 0.125=a$

$3=a$

Substitute a=3 and b=0.5 in equation (1).

$y=3(0.5)^x$

Therefore, the correct option is B.

Given that the line is x/3 + y/2 =1 i ) make y the subject ii ) gradient of line

miss Akunina [59]

Answer:

see explanation

Step-by-step explanation:

(i)

$\frac{x}{3}$ + $\frac{y}{2}$ = 1 ( multiply through by 6 to clear the fractions )

2x + 3y = 6 ( subtract 2x from both sides )

3y = - 2x + 6 ( divide through by 3 )

y = - $\frac{2}{3}$ x + 2

(ii)

The equation of a line in slope- intercept form is

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

y = - $\frac{2}{3}$ x + 2 ← is in slope- intercept form ( that is part (i)

with gradient m = - $\frac{2}{3}$

PLS I NEED HELP! Which graph grows the fastest as x gets larger?

jok3333 [9.3K]

Answer:

y=5^x

Step-by-step explanation:

5 to whatever power will always be larger than 4, 3, or 2.

For example:

3 squared = 9

5 squared = 25

4 squared = 16

2 squared = 4

25 is greater than 9, 16, and 4
