The y-intercept for the cubic function: 4x^3-3x^2+7 is (0, 7)
Given the polynomial function 4x^3-3x^2+7, the y-intercept of the function occurs where the value of x is zero
Substituting x = 0 into the polynomial function will give;
y = 4x^3-3x^2+7
y = 4(0)^3-3(0)^2+7
y = 0 - 0 + 7
y = 7
Hence the y-intercept for the cubic function: 4x^3-3x^2+7 is (0, 7)

the locus of all points that are the same distance from (3,-2) and (3,4) is one straight line. Draw this straight line
Answer:
No answer i can provide
Step-by-step explanation:
If you need to make a line on a graph, you need to plot at least 2 points. Luckily, the two points have been given.
Plot the points on your graph. for your first coordinate, go 3 over and down 2. for your second point, go over 3 and up by 4. for the line, draw it through your 2 points.
Hope this helps!
Answer:
line is y = 1
Step-by-step explanation:
the question is talking about loci, in this case 2 point
these 2 points are (3,-2) and (3,4)
draw a line to connect these to points and bisect the line.
to do this use a compass : put the compass more than half way and place it one the first point - draw an arc .
then draw another arc at the sencond point
were the 2 arcs meet draw a line - this straight line will be the answer.
y = 1
Write an equation in slope-intercept form of the line please help me
Answer:
The formula is generally represented equationally as ( y - Y1 ) = m( X - X1 ) so now let's substitute the points plotted on the graph.
it is equal to (y - 4) = m(x - 0)
and now we look for the slope
m = y2 - y1/ x2 - x1
which can be directly substituted according to every line connecting each x value to a certain y value.
Solving the quadratic equations using by completing the square.

Show ALL your work to receive credit
Answer:
78
Step-by-step explanation:
You use the formula
[tex] \frac{f(b) - f(a)}{b - a} [/tex]
with a=2 and b=5 plug it in to the formula
[tex] \frac{f(5) - f(2)}{5 - 2} [/tex]
find the values
[tex]f(5) = {3}^{5} + 4 = 247 [/tex]
[tex]f(2) = {3}^{2 } + 4 = 13[/tex]
put it all together
[tex] \frac{247 - 13}{5 - 2} = \frac{234}{3} = 78[/tex]

Is this right? Please let me know
Answer:
See below:
Step-by-step explanation:
No, it appears to be incorrect if its based off the image you have provided.
I can help you make it correct though.
I'll take you through 2 steps to solve the problem, one being Equations and another being Graphing.
Equations
So, to find the slope, we need to get an equation. Most slope's are in the [tex]y=mx+b[/tex] form which have a few components that we need to know to figure it out.
[tex]m[/tex] is the slope of the line.[tex]b[/tex] is the y intercept: (0,b)Now that we know this, we can start breaking i down and soon begin graphing.
The y intercept is one point that we can use to start the line, as the question says to graph the line, we need to start by using the y intercept as one point on the line which would be (0,6) so that would be one point.
Graphing
To graph the line, we need to find the y intercept and another point. For example, we found the y intercept in the previous section, and it was (0,6). We can find another point by just looking at the slope. The slope of the line is 3 so we would go up 3 right 1 from our point to get our second point.
So, our points would be:
(0,6)(1,9)Cheers!
you're so cool! I hope you have an awesome day!
Answer:
The functions each have a positive Slope
a.)True, False
Step-by-step explanation:
Function A Slope: (y2-y1)/(x2-x1) = (7-3)/(2-1) = 4
Function B Slope: Count Four Boxes up from the 2 intercepts and then 2 over --> 4/2 = 2
These are both positive but 4 does not equal 2
a.) We have just proved that they have different slopes now we must determine if they have the same b. Because we know the slope of Function A we can simply move backward to get to x=0
When X=0 y= 3-4 = -1 And because in Function B we can clearly see the b at y=4 this is false.
Hope this helps and makes you have an Awesome Day!

8. Twice the greatest of three consecutive integers is 10 more that the smallest integer. Find the 3 integers.
Answer:
6, 7, 8
Step-by-step explanation:
Let the smallest integer be x.
The next greater one is x + 1.
The greatest of the three is x + 2.
Now we use the sentence "Twice the greatest of three consecutive integers is 10 more that the smallest integer." to write an equation.
2(x + 2) = x + 10
Solve the equation for x to find the smallest of the integers.
2x + 4 = x + 10
x = 6
The next one is x + 1.
x + 1 = 7
The greatest is x + 2.
x + 2 = 8
Answer: 6, 7, 8
Answer:
6, 7, 8
Step-by-step explanation:
You can set up variables to represent each of these integers.
For example: x, x+1, and x+2. Next find out what x is by using what the question has told you.
Since twice the greatest of three consecutive integers is 10 more than the smallest integer, you can set up this equation: (x) + 10 = 2(x + 2). x represents the smallest integer while x + 2 represents the greatest integer.
Next solve for x using PEMDAS.
1. (x) + 10 = 2(x + 2)
2. x + 10 = 2x + 4
3. 2x - x = 10 - 4
4. x = 6
Now you can find the other integers by adding 1 and 2 to 6.
The correct answers should be 6, 7, 8.

If a bag contains 10 blue marbles, 5 green Marbles, and 3 red marbles, What is the ratio of red marbles to all Marbles? be sure to simplify/ an equivalent ratio
Answer:
1 red marble to 6 total marbles
Step-by-step explanation:
There are 3 red marbles, and (10 + 5 + 3) total marbles.
There are 3 red marbles to 18 total marbles
therefore the ratio is 3 to 18 which can be simplified by dividing both sides of the ratio by 3
the ratio is 3/3 : 18/3 which is 1:6

Find the perimeter. Simplify your answer.
Answer:
10u-16
Step-by-step explanation:
Formula for perimeter of a rectangle is 2l+2w, where l and w represent length and width respectively. Applying this formula here, we get 2(5u-10)+2(2), which is a simple expression to simplify:
2(5u-10)+2(2) = 2(5u)-2(10)+2(2) = 10u-20+4 = 10u-16
Answer:
10u - 16Step-by-step explanation:
Perimeter = 5u - 10 + 5u - 10 + 2 + 2

Solve each given equation and show your work. Tell whether each equation has one solution, an infinite number of solutions, or no solution. Explain your answers.
(a) 2x + 4 (x - 1) = 2 + 4x
(b) 25 - x = 15 - (3x + 10)
(c) 4x = 2x + 2x + 5 (x - x)
Answer:
Step-by-step explanation:
(a) 2x + 4 (x - 1) = 2 + 4x
2x +4x - 4 = 2 + 4x
6x -4 = 2 + 4x
2x = 6
x = 3 One solution
(b) 25 - x = 15 - (3x + 10)
25 - x = 15 - 3x - 10
2x = 15 - 25 - 10
2x = -20
x = -10 One solution
(c) 4x = 2x + 2x + 5 (x - x)
4x = 4x + 5x - 5x
0 = 0
No solutions
