solve the following system by substitution y=5x-4 y=6x
Answer:
Step-by-step explanation:
y = 5x - 4
y = 6x $\Rightarrow$ x = y/6
y = 5*y/6 - 4
y = 5y/6 - 4
6y = 5y - 24
y = -24.
So, x = -4

Jerome deposits $3,700 in a certificate of deposit that pays 1.8% interest, compounded
annually. How much interest does Jerome earn in 1 year?
Answer:
$66.60
Step-by-step explanation:
Find out how much money Jerome earns from the 1.8% interest.
100% = 3700
1% = 3700 ÷ 100 = 37
1.8% = 37 x 1.8 = 66.60

Can a set of data have more than one line of best fit? Why or why not?
Line of best fit refers to a line through a scatter plot of data points that best expresses the relationship between those points. Statisticians typically use the least squares method to arrive at the geometric equation for the line, either though manual calculations or regression analysis software. A straight line will result from a simple linear regression analysis of two or more independent variables. A regression involving multiple related variables can produce a curved line in some cases.
one thanks give me motivation for answering
plz follow me
plz mark me brainliest
What is the slope of the line that passes through the points (48, 10) and (-36, 17)?
Answer:
y = m x + b equation of a straight line
m = (y2 - y1) / (x2 - x1) slope of line
m = (17 - 10) / (-36 - 48) = 7 / -84 = -1 / 12
y = -x / 12 + b equation of line
Or b = y + x / 12
If y = 10 and x = 48 then b = 10 + 48 / 4 = 14
if y = 17 and x = -36 then b = 17 - 36 / 12 = 14
So b = 14 and y = -x / 12 + 14

Is 3 a factor of 245 - 16?
yes
no
HELPPP
Answer:
No
Step-by-step explanation:
For 3 to be factor your finale number has to be divisible by 3, so with that information all you have to do is subtract 245-16 which is 229, and if you divide 229 by 3 it does not equal a whole number so 3 cannot be a factor.
I hope this helps, and have a great day! :D
