what is an equation of the line that passes through the point (-2,-8) and has a slope of 3?
a) y=3x-2
b) y=3x-22
c) y=3x+2
d) y=3x+22
Answer:
y = 3x -2
Step-by-step explanation:
General equation of a line in the slope intercept form is
y = mx + b ,
where m is the slope and b is the y-intercept ( where intercepts the y-axis)
y = 3x + b ,
because is given slope is m = 3
For point (x = -2, y = -8) we have
-8 = 3 (-2) + b
-8 = -6 + b
-8 + 6 = b
-2 = b
The equation of the line that passes through the point (-2,-8) and has a slope of 3 is
y = 3x -2

Rachel currently has $836 in a savings account that has earned 4. 5% annual compound interest for the past year. What was Rachel’s beginning balance one year ago if she has made no other deposits during the year?
Rachel's beginning balance one year ago was $800.
What is compound interest?Compound interest is applicable when there will be a change in the principle amount after the given time period.
For example, if you give anyone $500 at the rate of 10% annually then $500 is your principle amount. After 1 year the interest will be $50 and hence principle amount will become $550 now for the next year the interest will be $550, not $500.
Given that,
The current balance is $836 which is the result of compound interest of 4.5 % annually.
The original amount was a priciple amount P on which interest was applied and the final amount $836 made.
Compound interest formula;
A = P[ 1 + RT/100]^T
Where A is the final amount and T is the time period.
Here,
A = 836 , R = 4.5% and T = 1 year.
So,
836 = P[1 + 4.5/100]^1
P = 836/1.045 = $800
Hence "Rachel's beginning balance one year ago was $800".

ABC ~ DEF. What sequence of transformations will move ABC onto DEF?
The transformation that is implemented is clockwise rotation by 270° about the origin and dilation by a scale factor of 1/2 .
The process of transformation an existing graph or equation into a new graph is known as graph transformation . The alteration of algebraic equations is a typical form of algebraic challenge.
A transformation modifies the graph of a parent function. Dilations, reflections, and translations are the three distinct types of transformation . The y-values of a function can be changed vertically, or the x-values can be changed horizontally (affects the x-values).
In the given figure we can see that the length of the side BC of the figure is 4 units, where as the length of the corresponding side in the image is
2 units . Hence the image is dilated buy a scale factor of 1/2 .
And from the transformation figure it is clear that the image has rotated either 270° clockwise or 90 ° counterclockwise.
Hence the second option on transformation is correct.

The total of Melinda's expenses for the week is $93.04 option (c) $91.94 is correct.
What is expenses?It is defined as the money spends on the utility, the amount of money is required to buy something in other words it is the outflow of money from the solely earners income or the money incurred by any organization.
Melinda kept a record of her spending for the week as follows:
The amount she spent money to put gas in the car = $25
The amount to buy a new shirt = $22.38
The amount to play putt-putt golf with some friends = $6.95
The amount to buy groceries = $38.71
To calculate the total expenses for the week, we must add all the expenses:
= $25+$22.38+$6.95+38.71

Noah says the second lake is generally deeper than the first lake. Do you agree with Noah?
No, I do not agree with Noah because the second lake has greater variability with a higher MAD so even though the mean depth is deeper the data is very spread out away from that mean.
No, I do not agree with Noah. The MAD tells us how deep it is and the 1st MAD is more.
Yes, I agree with Noah. The MAD tells us how deep it is and the second MAD is more.
