Answer: x=(c-k) over 3
Step-by-step explanation:Here we are given the equation 3x+k =c
Here in order to solve for x , first let us bring k to the right side.
k is in addition on the left , so when we bring it to the right it gets subtracted
now we have to isolate x on the left side , 3 is in multiplication with x , so when we bring it to the right side we divide by 3
Answer=x=(c-k) over 3
Answer:
Adult tickets = 276
Step-by-step explanation:
a + s = 491 Eq. 1
a = s + 61 Eq. 2
a = adult tickets
s = student ticket
Replacing Eq. 2 in Eq. 1:
(s+61) + s = 491
2s + 61 = 491
2s = 491 - 61
2s = 430
s = 430/2
s = 215
from the Eq. 2
a = s + 61
a = 215 + 61
a = 276
Check:
from Eq. 1:
a + s = 491
276 + 215 = 491
Answer:
It cannot be the line of best fit because it is not closest to most of the points; and (0, 15) and (10, 1)
Step-by-step explanation:
A screenshot of the first question is attached.
Graphing the points and drawing the line that is supposed to be the line of best fit, we can see that it is not very close to the majority of the points. This means it should not be used as the line of best fit.
For the second question, if we graph the points and draw a line between the first two, we get the second screenshot I've attached. It goes through the majority of points. However, if we draw a line through any of the other pairs of points, it does not go through the majority of points and thus would not be a line of best fit.
a function is a relationship or expression involving one or more variables. It has a set of input and outputs. Each input has only one output. The function is the description of how the inputs relate to the output.
