Answer:
a) 160 meters short
b) d = 200x +80y
c) (run, walk) = (2, 15), (4, 10), (6, 5)
d) see attached
Step-by-step explanation:
You're being asked to write an equation describing the gym class requirement, and to find several values of the variables that satisfy the equation.
It is convenient to write the equation first (part b).
__
b)At 200 meters per minute, in x minutes, Eric will run 200x meters. At 80 meters per minute, Eric will walk 80y meters in y minutes. His total distance covered will be ...
d = 200x +80y
__
a)In the given times, Eric's distance covered is ...
d = 200(4) +80(8) = 800 +640 = 1440 . . . meters
Eric is 160 meters short of the 1600-meter goal.
__
c)It is convenient to simplify the equation to one that lets us find one value in terms of the other.
200x +80y = 1600
5x +2y = 40 . . . . . . . . divide by 40
This will have integer solutions for even values of x in the range 0 to 8.
y = (40 -5x)/2
For x={2, 4, 6}, we have ...
y = (40 -5{2, 4, 6})/2 = {30, 20, 10}/2 = {15, 10, 5}
Eric can cover 1600 meters in (run, walk) times of ...
(run, walk) = (2, 15), (4, 10), (6, 5)
__
d)The graph is attached. We'll let you read as many values from it as you may wish.
What is the area of this rectangle? and brainleist
16 m
36 m
32 sq m
39 sq m
Answer:
39 sq m
Step-by-step explanation:
Since it asking for area:
Formula for area: A = Lw {Length x Width}
Thus,
A =wl = 3·13=39
We can also do
13 + 13 + 13 = 39
Hence, Answer is 39 sq m

Evaluate the expression 43 ÷ (7 − 3) × 2.
Answer: 21.5
Step-by-step explanation:
The order of operations are:
1) Parenthesis and Brackets
2) Exponents
3) Multiplication and Division (from left to right)
4) Addition and Subtraction (from left to right)
Parenthesis are first so let's solve them first
43 ÷ (7 − 3) × 2
43 ÷ (4) × 2
Now we only have division and multiplication
So we must do this from left to right, starting by 43 ÷ 4
43 ÷ 4 × 2
10.75× 2
Finally, multiply
10.75× 2
21.5

Linear Function K passes through points (-3,7) and (3,3). What is the rate of change of function K?
A) -3/2
B) -2/3
C) 3/2
D) 2/3
- 2/3 is the correct answer
Step-by-step explanation:
The rate of change of function K is -2/3. Therefore, option B is the correct answer.
What is rate of change a function?The rate of change, or the slope, is calculated as Δy/Δx , or (y2−y1)/(x2−x1). The slope-intercept equation of a line is y=mx+b , where m is the slope and b is the initial value.
Given that, linear function K passes through points (-3,7) and (3,3).
Now, the rate of change
= (3-7)/(3+3)
= -4/6
= -2/3
Therefore, option B is the correct answer.

Suppose a one year subscription to a magazine cost $12.99 and a three-year subscription cost $25.98 the cost and length of the subscription are related write an equation to a model the cost of a subscription for any period of time
Answer:
y = $38.97
y = 6.495(5) + 6.495
Step-by-step explanation:
So for this problem, since it states the cost and length of the subscription are related, you can use the two subscription costs as data (or coordinate) points.
1 year = 12.99, 3 year = 25.98; so (1,12.99), (3, 25.98) use these points to calculate the average rate of change (or the slope (m)).
(y - y1)/(x - x1) = m so, (25.98-12.99)/(3 - 1) = 6.495, this is the slope, m
y = 6.495(x) + b now just pick one of the points and put in the x and y values to solve for b
12.99 = 6.495(1) + b solve for b and you discover it also = 6.495 = b
so y = 6.495(x) + 6.495 is the equation of the line, to answer their question, just pop in x=5 for the 5 years subscription cost
y = 6.495(5) + 6.495
y = $38.97

Answer:
C. f(x) > g(x) for x > 2
Step-by-step explanation:
Using a graph is probably the easiest way to compare an exponential function with a polynomial function. There are no algebraic methods for finding points of intersection. ("Trial and error," or "table of values" will work.)
A graph of these two functions shows f(x) > g(x) except on the interval [1, 2]. That is, f(x) > g(x) for x > 2.
paula bought an electric drill at 75% of the regular price.She paid 32.90 for the drill. What was the regular price?(round to the nearest cent)
Answer:
$43.87.
