Determine the y-intercept of the following parabola:
y = 3x2 - 12x - 5
Answer:
-5
Step-by-step explanation:
Find the y-intercept by plugging in x = 0:
y = 3x^2 - 12x - 5
y = 3(0^2) - 12(0) - 5
y = 0 - 0 - 5
y = -5
(0, -5)
Um I kinda need help on this and how to do it
Answer:
m = 1
Step-by-step explanation:
Slope is defined by the change in y over the change in x, [tex]\frac{\Delta y}{\Delta x}[/tex]. A trick here is to find where 2 points where the slope intersects a corner of the square grids. For example, here, it can be (0,1) and (1,0). Then, you count how many squares you needed to go up or down by and divide by the number of square you needed to move right or left by. If you move up or right, the value will be positive and vice versa for down and left. Which direction you go will depend on which point you start on. Here, we can see between (0,1) and (1,0), we need to move up 1 and right 1. Meaning 1/1 is the slope or m = 1. If this doesn't make sense, just ignore it but it may come in handy when you move to more complex problems where the slope is a fraction or something.
Answer:
b= -1
m=1
Step-by-step explanation:
the equation for a linear graph is y=mx+b
your y intercept would be -1 because thats where the line crosses on the y axis. The slope which would be 1 is because when you are on the point (0,-1) you go up one and one to the right and get (1,0)
therefore the equation would be
y=1x-1 or y=x-1

Parker is working two summer jobs, making $11 per hour lifeguards and $22 per hour tutoring. Last week Parker worked a total of 16 hours and earned a total of $242. Determine the number of hours Parker worked lifeguarding last week and the number of hours he worked tutoring last week
Answer:
lifeguarding: 6 hours
tutoring: 10 hours
Step-by-step explanation:
First, to be able to tell apart the two jobs, use the variable x and y for them. use x for lifeguarding and y for tutoring. Since you have the pay per hour, you can create an expression for his pay:
11x + 22y
Then, write a system of equations to be able to find both variables.
If Parker worked a total of 16 hours, then you know that the combined amount of worked hours will be:
x + y = 16
If Parker earned a total of $242, then you know that his combined pay will be:
11x + 22y = $242
Now, you solve the system of equations (IMAGE.A):
First, solve for x:
11x + 22y = 242
11x = 242 – 22y
x = 22 – 2y
Now, plug in the x-value in the other equation:
x + y = 16
22 – 2y + y = 16
22 – y = 16
–y = –6
y = 6
This means that he has worked 6 tutoring hours.
Now, plug in the y-value to find the x-value:
11x + 22y = 242
11x + 22(6) = 242
11x + 132 = 242
11x = 110
x = 10
this means that he has worked 10 lifeguarding hours.
Answer:
10 hours lifeguarding, 6 hours tutoring

write the next three terms of the sequence.
Answer:
25, 34, 43
Step-by-step explanation:
-11 + x = -2, -11 + 9 = -2 -2 + x = 7, -2 + 9 = 7, 7 + 9 = 16 -2 - x = -11, -2 - 9 = -11 7 - x = - 2, 2 + x = 11, 11 - 2 = 9, 9 = x 7 - 7 = 0 - 2 = -2, 7 + 2 = 9, 7 - 9 = -2
16 + 9 = 25, 25 + 9 = 34, 34 + 9 = 43

Which of the following are true statements about any regular polygon? Check all that apply.
Answer:
A regular polygon has these characteristics:
3 or more sidesClosed shapeA polygon can not have one or two sides because that would be a line. It must have more than three sides, or else it is not a polygon.
A polygon is always a closed shape - it can not be an open shape or else it would not be a polygon, it would be considered an outline.

In last weekend's track meet, Lakeland High School had 30 individual-
event placers score a total of 111 points. First-place finishers score 7 points, second-place finishers score 4 points, and third-place finishers score
1 point. The number of first- and second-place finishers was twice the
number of third-place finishers. Find the number of runners that finished in
each place.
Answer:
The number of runners that finished in first place , second place and third place are 7 , 13 and 10 respectively.
Step-by-step explanation:
Let the no. of runners fished at first place be x
Let the no. of runners fished at second place be y
Let the no. of runners fished at third place be z
We are given that Lakeland High School had 30 individual- event placers
So, x+y+z=30 -----1
First-place finishers score 7 points
So, Total score of x runners = 7x
Second-place finishers score 4 points
So, total score of y runners = 4y
Third-place finishers score 1 point.
So, total score of z runners = z
We are given that 30 individual- event placers score a total of 111 points
So, 7x+4y+z=111 ----2
We are also given that The number of first- and second-place finishers was twice the number of third-place finishers.
x+y=2z ---3
Substitute the value from 3 in 1
x+y+z=30
2z+z=30
z=10
Substitute the value of z in 1 and 2
x+y=20 ----4 and 7x+4y=101 ---5
Substitute the value of x from 4 in 5
7(20-y)+4y=101
140-7y+4y=101
140-3y=101
39=3y
`13=y
Substitute the value of y and z in 1
x+13+10=30
x=7
Hence the number of runners that finished in first place , second place and third place are 7 , 13 and 10 respectively.

Lines l and m are vertical with l to the left of m. Transversal t intersects them both slanting down and right. The angles formed above t with l and m from left to right are angles 1, 3, 5, and 7. The angles formed below t with l and m from left to right are angles 2, 4, 6, and 8. Select all the angles that are supplementary to ∠1. Group of answer choices ∠3 ∠4 ∠6 ∠5 ∠7 ∠8
Answer:
∠6 and ∠7
Step-by-step explanation:
To be complementary, they both in total have to sum 180°, and that mean that they have to form a com pleat and straight line. ;)
The supplementary angles of angle 1 are angles 2 and 3.
Two Angles are Supplementary when they add up to 180 degrees.From given figure,
It is observed that sum of angles 1 and 2 is equal to 180 degrees.The sum of angles 1 and 3 is equals to 180 degrees.[tex]\angle1 +\angle2=180\\\\\angle1 +\angle3=180\\[/tex]
Thus , the supplementary angles of angle 1 are angles 2 and 3.

Given these processes: 1. cartilage ossification 2. bony callus formation 3. hematoma formation 4. fibrocartilaginous callus formation 5. remodeIing of woven (spongy) bone into compact bone Which sequence best represents the order in which the processes occur during repair of a fracture?
Answer:
The sequence that best represents the order during repaid of a fracture as as
follows
3. hematoma formation
4. fibrocartilaginous callus formation
2. bony callus formation
1. cartilage ossification
5. remodeling of woven (spongy) bone into compact bone
Step-by-step explanation:
When a bone is fractured, the first step following a bone fracture is hematoma formation.
Hematoma formation is formed when a little blood escapes from the blood vessels and remains in the skin's thickness, creating a blue spot. The hematoma is an effusion of blood that occurs deeper under the skin.
From there, the formation of tissues begins from end to end of the broken bones. It is a reorganization of the bone tissue (the bone itself), allowing the consolidation of a fractured bone. This bone formation welds the two parts of the broken bone together for a particular period depending on the patient's bone tissue condition. This bone callus will form in two episodes.
1) There first appears a fibrocartilaginous callus, also called connective callus, which allows the fracture to heal in a few weeks. It is an immature bone.
2) In a second step, this immature bone is gradually replaced by another bone (calcified/bony) resembling the bone which has been fractured.
From there, the ossification of the callus occurs where the bony callus is further replaced by woven spongy bones to form a stronger stabilizing collar.
Finally, the remodeling of woven (spongy) bone into compact bone takes place. Lamellar bones are replacing these woven spongy bones.

Answer:
13 seconds
Step-by-step explanation:
Since distance is directly proportional to time,
distance = time * a constant
Lets make A the constant
So, 54 = 9A
A = 6
Now, since distance = 78,
78 = time * A
From above, we can see that A = 6, so
78 = time *6
time = 13
Answer:
13
Step-by-step explanation:
54/9=6, 6 is the rate at which the car travels. 78/6 is 13 so that is how far the car traveled
