4^(x- 3) = 18

ln[4^(x- 3)] = ln(18)

ln4(x - 3) = ln(18)

ln4x - ln4(3) = ln18

ln4x = ln18 + 3ln4

x = [ln18 + 3ln4]/ln4

x = 5.0849625007

x is approximately 5.085.

marshall27 [118]
First, find the function that represents x and y.

x is the number of 8 oz jars
y is the number of 16 oz jars

function: 8x + 16y = 240

x-intercept: y = 0 => 8x = 240 => x = 30 => (30,0)
y-intercept: x = 0 => 16y = 240 => y = 15 => (0, 15)

Answer: (0,15) and (30,0)

Answer:

7*6-x

or

42-x

Step-by-step explanation:

decrease means subtraction,

product means multiplication

let x be the number you are decreasing by.

I am not really sure how to explain this, but here I go.

you take away x from the number that equals 6*7.

6*7 is 42 and you take away x from that, you get 42-x

or if you want to leave it unsimplified,

6*7-x

Rewrite the following equation in slope-intercept form.<br> 6x + 13y = -10
Sedbober [7]

Answer:

y= -6x/13 -10/13

Step-by-step explanation:

first you'll subtract 6x from both sides

6x+13y=-10

-6x .      -6x

13y=-6x-10

then you divide by 13 to get y by itself

y= -6x/13 -10/13
