Yosune walked her dog 5 miles today and plans to walk her dog 2.5 miles everyday from now on. The total number of miles walked y can be represented by y=2.5x+5 where x is the number of days walkef
Answer:
The answer is below
Step-by-step explanation:
Yosune walked her dog 5 miles today and plans to walk her dog 2.5 miles every day from now on. The total number of miles walked y can be represented by y = 2.5x + 5, where x is the number days walked after today. a. State the x- and y-intercepts and then graph the equation. b. Interpret the x- and y-intercepts.
Solution:
The equation for a linear function is given by:
y = mx + b; where m is the slope of the function and b is the y intercept.
Given the equation y = 2.5x + 5, the y and x intercept can be found by substituting x = 0 and y = 0. Hence:
a) x intercept is the value of x when y = 0. Therefore:
0 = 2.5x + 5
2.5x = -5
x = -2
y intercept is the value of y when x = 0. Therefore:
y = 2.5(0) + 5
y = 5
b) The x-intercept is at the point (–2, 0). But there cannot be a negative number of days walked, hence the x intercept does not apply in this situation.
The y intercept is at the point (0, 5). This means that Yosune has initially walked her dog 5 miles.

Answer:
A. 86.7
first, the base. length x width.
it's square, so
5.1 x 5.1= 26.01
then the sides. formula for a triangle is base times height divided by 2.
5.1 x 5.95= 30.345 divided by 2 is 15.1725
there are 4 sides, so multiply times 4
4 x 15.1725= 60.69
now, add the base to the sides
26.01 + 60.69= 86.7

1.5 times 8 =12The sum of two numbers is 59 and the difference is 11
Answer:
35 and 24
Step-by-step explanation:
35 + 24 = 59
35 - 24 = 11
Answer:
24 and 35
Step-by-step explanation:
x + y = 59
x - y = 11, then x = y + 11
substitute for x:
y + 11 + y = 59
simplify:
2y + 11 = 59
subtract 11 from each side of the equation:
2y = 48
divide both sides by 2:
y = 24
x = 35

Answer:
No, 16t -3t equals 13t while 3t - 16t equals -13t
Answer:
No,
16t= 16x2=32
3t=3x2=6
32-6=26
3t=3x2=6

Write a function that represents the total cost of your family's outing to the soccer game after x hours.
Answer:
Please attach an image.
f(x) = (cost)x
Answer:
c=s*x
Step-by-step explanation:
C will be the total cost of our family's outing to the soccer game
While x will be the hours
and S will be the soccer game
So s*x will equal the cost
Making c=.

Answer:
36
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees
<A+ <B+ <C = 180
2x+6x+2x = 180
10x = 180
Divide by 10
10x/10 = 180/10
x = 18
We want to find <C
<C = 2x
= 2*18

Joe buys 6 adult tickets and 4 child tickets for the movies. Each adult ticket cost $9. Each child ticket cost the same amount. Joe pays with a $100 bill and gets $22 in change. How much does each child ticket cost?
Answer:
Each child ticket cost = $6
Step-by-step explanation:
Joe has = $100
His balance after tickets purchase = $22
Actual amount spent on tickets = $100 - $22 = $78
But,
Each adult ticket cost = $9
Total no of adult = 6
Total amount spent (adults) = $9 x 6 = $54
Balance remaining = $78 - $54 = $24
Amount spent of 4 child tickets = $24
No of children = 4
Therefore,
Amount spent on 1 child (1 ticket),
= $24/4 = $6.
It could be seen that each child ticket cost six dollars.

The value of the function f(x) is 600 when x=0 and decreases by 9% for every one-unit increase in x. Complete the equation that represents the function f(x)
its a open answer please help
Answer:
[tex]f(x)=600(0.09)^x[/tex]
Step-by-step explanation:
Since f(x) decreases by 9% for every one unit increase in x, it means that f(x) is an exponential decay function. An exponential function is given by:
f(x) = [tex]ab^x[/tex]; where a is the value of f(x) at x = 0, b is the multiplier and is less than 0 for a decay.
Therefore since at x = 0, f(x) = 0. Hence a = 600. Also, b = 9% = 0.09.
The function f(x) can hence be represented as:
[tex]f(x)=600(0.09)^x[/tex]

Determine a pair of angles (one positive and one negative) in degree measure coterminal to the angle 117°.
Answer:
Option B.
Step-by-step explanation:
When we have an angle A, in degrees, the coterminal angles are all the angles that can be written as:
B = A + n*360°
Where n is a positive or a negative integer (if n = 0, then B = A, which means that A is coterminal with itself, which is trivial).
Now we want to find two coterminal angles to 117°, such that one is positive and the other negative.
Then we can do:
for the positive one, use n = 1.
B = 117° + 1*360° = 477°
For the negative one, use n = -1
B = 117° - 1*360° = -243°
Then the two angles are 477° and -243°
The correct option is B.
