D=collector value of a dime
H=collector value of a half dollar
S=collector value of a silver dollar
Write a linear equation showing the number of each coin
A) 0.50d+1.50h+8s=231
B) 5d+3h+8s=231
C) d+h+8s=231
D) 0.10d+0.50h+1s=231
PLS HELP! I’ll give brainliest
Answers
The amount in equation is 5d + 3h + 8s = 231.
What is linear equation?A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.
Given:
Jeremy had 5 Roosevelt dimes,
3 Kennedy half dollars,
and 8 silver dollars in his coin.
Total amount = $231
As, let d be the collector value of a dime
let h be the collector value of a half dollar
let s be the collector value of a silver dollar
Now, to represent the amount in equation
5d + 3h + 8s = 231

Step-by-step explanation:
The mean absolute deviation of the data is 11.
The mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean.
To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values.

John recorded the weight of his dog Spot at different ages as shown in the scatter plot below.
Part A:
Write an equation that would describe the line of best fit.
Part B:
Using the line of best fit, make a prediction of Spot's weight after 18 months.
Answers
Answer:
A) y = 1.875x + 1.25
B) 35 pounds
Step-by-step explanation:
A) We need two points to define a line. To find an equation that would describe the line of best fit, we can use one of the first points and one of the last points. Let's use (2, 5) and (10, 20).
General equation of a line:
y = mx + b
Slope of the line:
m = (20 - 5)/(10 - 2) = 1.875
y-intercept is found replacing a known point and the slope into the general equation:
5 = 1.875*2 + b
b = 5 - 1.875*2 = 1.25
The final equation is:
y = 1.875x + 1.25
where y represents weight (in pounds) and x represents age (in months)
B) At x = 18:
y = 1.875*18 + 1.25 = 35

to the line representing the equation y = - 5/7x + 2?
Answers
Answer:
y = 7/5x + 4
Step-by-step explanation:
use the slope from the equation -5/7 and take the negative reciprocal to get the perpendicular slope = 7/5. Then use the equation y=mx+b. Plug in x and y from the point given and the new slope and solve for b.
(-3) = (7/5)(-5) + b, (-3) = -7 + b, add 7 to both sides. b = 4. Rewrite the equation now to be y = 7/5x + 4
