7. The graph to the right represents the distance (y) Kirk has walked after x seconds.
a. What is the slope-intercept equation for the graph?
b. Predict how far Kirk will have walked after 72 seconds.
Answer:
a). y = 1.6x
b). Distance traveled = 115.2 feet
Step-by-step explanation:
From the graph attached,
A). Distance traveled by Kirk ∝ Duration of walk
D ∝ t
D = kt
Or y = kx
Since a point (5, 8) lies on the line given in the graph,
8 = 5k
k = [tex]\frac{8}{5}[/tex] = 1.6
Therefore, equation will be,
y = 1.6x
B). We have to find the distance walked after 72 seconds.
By putting x = 72 seconds
y = 1.6 × 72
= 115.2 feet
Distance traveled by Kirk = 115.2 feet
In exercise 14 and 15, the value of the surface area of the cylinder is equal to the value of the volume of the cylinder. Find the value of x. then find the surface area and volume of the cylinder. 14)With the height of x and base of 6ft 15) with the height x and base of 10 m
Answer and explanation:
Volume of a cylinder = π r² h
Surface area of a cylinder = 2π r h + 2π r².
Since volume of cylinder = surface area of cylinder
π r² h=2π r h + 2π r²
Solving 14)
Given height x and base 6ft, radius will be 3ft
π r² h=2π r h + 2π r²
22/7*3²*x= 2*22/7*3*x+2*22/7*3²
=22/7*9*x= 2*22/7*3*x+2*22/7*9
= 28.286x=18.857x+2*28.286
=28.286x=18.857x+56.572
=9.429x=56.572
x=5.999ft( x cannot be a negative value)
15) Given height x and base 10 m, radius will be 5m
π r² h=2π r h + 2π r²
22/7*5²*x= 2*22/7*5*x+2*22/7*5²
78.5714x= 31.429x+157.1428
47.1424x=157.1428
x=3.333m( because x cannot be negative)

1. Which equation represents a line that is perpendicular to the line represented by 2x - y =7
The equation that represents a line that is perpendicular to the line represented by 2x - y = 7 is y = -1/2x + 6
Equation of a lineThe equation of a line in slope-intercept form is expressed as;
y = mx + b
where;
m is the slope
b is the y-intercept
For two lines to be perpendicular, the product of their slope must be -1
Given the equation 2x - y =7
Rewrite
y = 2x - 7
The slope of the line is 2, the slope of the line perpendicular must be -1/2. Hence from the given option, the equation that represents a line that is perpendicular to the line represented by 2x - y = 7 is y = -1/2x + 6

Translate (in terms of x) then solve the algebraic equation: Five times the sum of 6 and some number is 20. HELPPPPP PLEASE HELP I REALLY NEED HELP
Answer:
The answer is 5 ( 6 + x ) = 20
Step-by-step explanation:
Five times = You are multiplying 5 to a number(s)
Sum of 6 and some number = Sum means to add. You are adding 6 to an unknown number.
In terms of x = You do not know what you are adding 6 with. Therefore 6+x.
is 20 = The total is 20.
To solve:
5 ( 6 + x ) = 20
30 + 5x = 20 Use the distributive property and multiply 5 to the 6 and the x
-30 + 5x = -30 Subtract the 30 on both sides
5x = -10 The 30's would cancel each other out and this is what's left
5x/5 = -10 / 5 Divide 5 on both sides.
x = -2 The 5 cancels each other on the left side.
x = -2 Is your answer

jada has already taken 4 pages of notes on her own, and she will take 2 pages out during each class session. In all, how many classes did jada attend if she rae out 56 pages ? explain how you know
Answer:
26
Step-by-step explanation:
I don't totally understand you question but if its 4 pages originally then she takes 2 pages every class, then
56-4= 52 (56 pages minus the 4 she already took).
52/2= 26 (52 pages divided by 2 pages per class)

Step-by-step explanation:
1. Well first I had to reduce 8/10. I found out that it is, when reduced, is 4/5. 4/5 is bigger than 3/8.
2. 10/10 and 8/8 are both equal to 1. So they are both equal.
3. none of those fractions had to reduced. Now 5/8 is bigger than 3/16.
1.8 -0.4y = 2(1.1 - Y)
Answer:
y=0.25
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
1.8−0.4y=2(1.1−y)
1.8+−0.4y=(2)(1.1)+(2)(−y)(Distribute)
1.8+−0.4y=2.2+−2y
−0.4y+1.8=−2y+2.2
Step 2: Add 2y to both sides.
−0.4y+1.8+2y=−2y+2.2+2y
1.6y+1.8=2.2
Step 3: Subtract 1.8 from both sides.
1.6y+1.8−1.8=2.2−1.8
1.6y=0.4
Step 4: Divide both sides by 1.6.
1.6y/1.6 = 0.4/1.6
Please help - find the orthocenter.
Answer:
Step-by-step explanation:
The line RS has a vertical line running through S. The line has the equation of x = - 1
The line running through R (the origin) has a slope to be determined by the points TS
T=6,0
S=-1,4
m = (y2 - y1) / (x2 - x1)
m = (4 - 0)/(-1 - 6)
m = 4/-7
The line you want going through 0,0 has a slope of m1 * m2 = -1 where m1 = -4/7
-4/7 * m2 = - 1
m2 = -1/(-4/7) = 7/4
Since the line goes through 0,0 the equation is y = 7/4 x
====================
The orthocenter must be on a y value determined by x = - 1
The orthocenter is (-1,-7/4)
y = 4/7
The orthocenter is (-1,4/7)

Which ordered pair is in the solution set of the system of equations shown below? Y^2-x^2+32=0 and 3y-x=0. A. (2,6) B. (3,1) C. (-1,-3) D. (-6,-2)
Answer:
The ordered pair (-6, -2) is in the solution set of the system of equations shown below ⇒ D
Step-by-step explanation:
To find the ordered pair that is in the solution set of the system of the equation substitute x and y in each equation by the coordinates of the ordered pair, if the two sides of equations are equal, then the ordered pair is in the solution set of the system of equations
∵ The equations are y² - x² + 32 = 0 ⇒ (1) and 3y - x = 0 ⇒ (2)
∵ The 1st ordered pair is (2, 6)
∴ x = 2 and y = 6
→ Substitute them in equation (2) first
∵ The left side = 3y - x
∴ The left side = 3(6) - 2 = 18 - 2 = 16
∵ The right sides = 0
∴ Left side ≠ Right side
∴ (2, 6) is not a solution to the system of equations
∵ The 2nd ordered pair is (3, 1)
∴ x = 3 and y = 1
→ Substitute them in equation (2) first
∵ The left side = 3y - x
∴ The left side = 3(1) - 3 = 3 - 3 = 0
∵ The right sides = 0
∴ Left side = Right side
→ Substitute them in equation (1)
∵ The left side = y² - x² + 32
∴ The left side = (1)² - (3)² + 32 = 1 - 9 + 32 = 24
∵ The right sides = 0
∴ Left side ≠ Right side
∴ (3, 1) is not a solution to the system of equations
∵ The 3rd ordered pair is (-1, -3)
∴ x = -1 and y = -3
→ Substitute them in equation (2) first
∵ The left side = 3y - x
∴ The left side = 3(-3) - (-1) = -9 + 1 = -8
∵ The right sides = 0
∴ Left side ≠ Right side
∴ (-1, -3) is not a solution to the system of equations
∵ The 4th ordered pair is (-6, -2)
∴ x = -6 and y = -2
→ Substitute them in equation (2) first
∵ The left side = 3y - x
∴ The left side = 3(-2) - (-6) = -6 + 6 = 0
∵ The right sides = 0
∴ Left side = Right side
→ Substitute them in equation (1)
∵ The left side = y² - x² + 32
∴ The left side = (-2)² - (-6)² + 32 = 4 - 36 + 32 = 0
∵ The right sides = 0
∴ Left side = Right side
∴ (-6, -2) is a solution to the system of equations
The ordered pair (-6, -2) is in the solution set of the system of equations shown below
