Answer:
x - intercept = 6
y - intercept = 3
Step-by-step explanation:
To find x - intercept, substitute y = 0 in the equation and solve for x.
x = 6
Similarly, To find y - intercept, substitute x = 0 in the equation and solve for y.
y = 3
Answer:
Step-by-step explanation:
<u>The x- intercept is the point when y = 0:</u>
- 3x + 4*0 = 32 ⇒ 3x = 32 ⇒ x = 32/3
<u>The y- intercept is the point when x = 0:</u>
- 3*0 + 4y = 32 ⇒ 4y = 32 ⇒ y = 8
Answer:
she took 13 classes that were worth 3 credits
Step-by-step explanation:
well we know that some of the classes are worth 3 and some are worth 4 and that all of these together = 59 so your first equation would be
3x+4y=59
x would be the number of classes worth 3 credits and y would be the number of classes worth 4 credits.
then it says the total number of classes that they took was 18 so we know that
x + y =18.
you want to solve for the number of 3 credit classes so lets go ahead and get rid of the y values. SO you need you multiply the x+y equation by 4
4x+4y=72
then subtract 4x+4y=72 from 3x+4y=59 to get
-x = -13
and then x is a negative so you need to divide -1 from both sides and you get that she took 13 classes that were worth 3 credits.
Answer:
x = 6
Step-by-step explanation:
The equation to solve is:

We can convert it to exponential form and find the answer. Below we show log to exponential form formula:

Now, we convert the log to exponential:

We now solve for "x",

We know the base number of log cannot be negative, so we disregard x = -6 and take x = 6 as our answer
