Answer:
y= -12x - 42
Step-by-step explanation:
slope intercept form is y=mx +b
y-6 = -12(x+4) simplify
y - 6 = -12x - 48 separate y by adding 6 to both sides of the equation
y = -12x - 42

This graph shows the distance vs. time relationship for the Lane 1 and Lane 2 turtles. Here are their equations:
Lane 1: d= 6+ 1t
Lane 2: d = 3t
Select all of the true statements.
(Select all that apply.)
1. The Lane 2 turtle is faster than the Lane 1 turtle.
2. At 3 seconds, the turtle in Lane 2 is 12 feet from the start.
3. At 12 seconds, the turtle in Lane 1 is 6 feet from the start.
4. The Lane 1 turtle has a head start.
Answer:
True statements are:
(i) The lane 2 turtle is faster than the lane 1 turtle.
(iv) The lane 1 turtle has a head start.
Step-by-step explanation:
Now we proceed to check the value of truth for each choice:
(i) The lane 2 turtle is faster than the lane 1 turtle.
Speed of the turtle is the slope of the linear function, the greater the slope, the faster the turtle. Hence, the lane 2 turtle is faster than the lane 1 turtle. (Answer: TRUE)
(ii) At 3 seconds, the turtle in Lane 2 is 12 feet from start.
Let the position of the turtle in Lane 2 be represented by [tex]d = 3\cdot t[/tex]. For [tex]t = 3\,s[/tex], then [tex]d = 3\cdot (3) = 9[/tex]. Hence, the turtle in Lane 2 is just 9 feet from the start. (Answer: FALSE)
(iii) At 12 seconds, the turtle in Lane 1 is 6 feet from the start.
Let the position of the turtle in Lane 1 be represented by [tex]d = 6 + t[/tex]. For [tex]t = 12\,s[/tex], then [tex]d = 6+12 = 18[/tex]. Hence, the turtle is 12 feet from the start. (Answer: FALSE)
(iv) The lane 1 turtle has a head start.
According to graph, Lane 1 turtle starts at a position of 6 feet, whereas Lane 2 turtle start at a position of 0 feet. Hence, Lane 1 turtle has a head start. (Answer: TRUE)

Lucy, Mary and Nora's father leaves them an inheritance in the
ratio 5: 3:2. Mary gets £4500, How much was there in total?
Answer:
£15000
Step-by-step explanation:
Lucy, Mary and Nora's father leaves them an inheritance in the
ratio 5: 3:2. Mary gets £4500, How much was there in total?
Giving the ratio of inheritance 5:3:2
5+3+2 = 10
Mary's ratio = 3
Marys share = £4500
Total share x can be gotten as thus
3/10 × x = 4500
3x/10 = 4500
3x = 45000
x = 45000/3
x = 15000
Hence £15000 was there in total

A sketch of the graph y = 2x² - 4x – 7 is shown.
Find the values identified as a, b, c, d and e on the sketch.
Answer:
a = (0, -7)
b = (1, 0)
c = (-9, 0)
d = (1 - 3√2 / 2, 0) ≈ (-1.1213, 0)
e = (1 + 3√2 / 2, 0) ≈ (3.1213, 0)
Step-by-step explanation:
----- points d and e ----
d and e we can find by solving for y = 0:
2x² - 4x - 7 = 0
2x² - 4x = 7
x² - 2x = 7/2
x² - 2x + 1 = 9/2
(x - 1)² = 9/2
x - 1 = √(9/2)
x = 1 ± 3√2 / 2
x ≈ 1 ± 2.1213
x ≈ 3.1213, -1.1213
So d is at approximately (-1.1213, 0), and e (3.1213, 0)
--- point a ---
Much easier to do, we simply need to solve for x = 0:
y = 2 × 0² - 4 × 0 - 7
y = -7
So point a is at (0, -7)
--- points b and c ---
We can find these in a couple of interesting ways. We've actually found b already, as it's halfway between points d and e. You'll recall that those are calculated as 1 ± 3√2 / 2, meaning that the midway point between them is just 1.
An alternate way of doing it is to apply some basic calculus, finding the point at which the curve has a slope of zero, which will give us b's x coordinate:
y = 2x² - 4x - 7
dy/dx = 4x - 4
0 = 4x - 4
4x = 4
x = 1
So b is equal to (1, 0).
To find c, we simply plug that x = 1 into the original function:
y = 2x² - 4x - 7
y = 2(1)² - 4(1) - 7
y = 2 - 4 - 7
y = -9
so c lies on (0, -9)
a = (0, -7)
b = (1, 0)
c = (-9, 0)
d = (1 - 3√2 / 2, 0) ≈ (-1.1213, 0)
e = (1 + 3√2 / 2, 0) ≈ (3.1213, 0)
What is co-ordinate geometry?A coordinate system in geometry is a method for determining the precise location of points or other geometrical objects on a manifold, such as Euclidean space, using one or more numbers, or coordinates.
Given
----- points d and e ----
d and e we can find by solving for y = 0:
2x² - 4x - 7 = 0
2x² - 4x = 7
x² - 2x = 7/2
x² - 2x + 1 = 9/2
(x - 1)² = 9/2
x - 1 = √(9/2)
x = 1 ± 3√2 / 2
x ≈ 1 ± 2.1213
x ≈ 3.1213, -1.1213
So d is at approximately (-1.1213, 0), and e (3.1213, 0)
--- point a ---
Much easier to do, we simply need to solve for x = 0:
y = 2 × 0² - 4 × 0 - 7
y = -7
So point a is at (0, -7)

y = -9
so c lies on (0, -9)

It costs $525 for seven adult tickets and twelve
youth tickets to the basketball game. If the
difference in price between an adult ticket and
a youth ticket is $18, find the cost of a youth
ticket.
Answer:
Youth ticket = $21
Adult ticket = $39
Step-by-step explanation:
We'll call adult tix x and child tix y. Based on the information given, we can make these two equations:
7x + 12y = 525
x - y = 18
Start by putting x in terms of y with that second equation
x = y + 18
Then substitute that into the first equation:
7(y+18) + 12y = 525
Then solve for y
7y + 126 + 12y = 525
19y = 399
y = 21
If we want the adult price as well, we know
x - 21 = 18
x = 39
Checking the math:
7(39) + 12(21) = 273 + 252 = $525

Triangle QRS is rotated 180° about the origin. On a coordinate plane, triangle Q R S has points (negative 4, 1), (negative 4, 4), (2, 1). What are the coordinates of point S'?
Answer:
D. (2, -1)
Step-by-step explanation:
I took the test and got it right.
Triangle QRS is rotated 180° about the origin. On a coordinate plane, triangle Q R S has points (-4, 1), (-4, 4), (2, 1). So, the coordinates of point S will be (2, -1).
How does rotation by 90 degrees changes coordinates of a point if rotation is with respect to origin?Let the point be having coordinates (x,y).
If the point is in first quadrant:
Subcase: Clockwise rotation:
Then (x,y) → (y, -x)
Subcase: Counterclockwise rotation:
Then (x,y) → (-y, x)
If the point is in the second quadrant:
Subcase: Clockwise rotation:
Then (x,y) → (y, -x)
Subcase: Counterclockwise rotation:
Then (x,y) → (-y, x)
Triangle QRS is rotated 180° about the origin.
On a coordinate plane, triangle Q R S has points (-4, 1), (-4, 4), (2, 1).
So, the coordinates of point S will be (2, -1).
