Write the simplest polynomial function for each set of zeros
Zeros = -2, 5, -1
Answers
Answer:
the answer should be y = x^3 - 2x^2 - 13x - 10
Step-by-step explanation:
x = -2 5 -1
x + 2 = 0
x - 5 = 0
x + 1 = 0
f(x) = (x + 2) (x + 1)
x(x) + 2(x) + x(1) + 2(1)
x^2 + 2x + x + 2
x^2 + 3x + 2
f(x) = (x^2 + 3x + 2) ( x - 5)
x^2(x) + 3x(x) + 2(x) + x^2(- 5) + 3x(- 5) + 2(- 5)
x^3 + 3x^2 + 2x - 5x^2 - 15x - 10
x^3 - 2x^2 - 13x - 10
f(x) = x^3 - 2x^2 - 13x - 10

y = 3x + 9
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
- 6x + 2y = 18 ( add 6x to both sides )
2y = 6x + 18 ( divide all terms by 2 )
y = 3x + 9 ← in slope- intercept form

Work out the equation of the straight line which has a gradient of 2
Answers
Note: It seems you may forget to write the complete statement. Maybe you should have either mentioned the y-intercept or any other point to work out the equation.
Anyways I am assuming your complete statement is ''Work out the equation of the straight line which has a gradient of 2 and passes through (1, 4)''.
Answer:
We conclude that the equation of a line using the slope-intercept form is
[tex]y=2x+2[/tex]Step-by-step explanation:
I am assuming your complete statement is ''Work out the equation of the straight line which has a gradient of 2 and passes through (1, 4)''.
The slope-intercept form of the equation
[tex]y=mx+c[/tex]
Here
m is the slopec is the y-interceptSubstituting the point (1, 4) and m=2 to determine the y-intercept
[tex]y=mx+c[/tex]
[tex]4 =2(1)+c[/tex]
[tex]4 = 2+c[/tex]
[tex]c = 4-2[/tex]
[tex]c = 2[/tex]
Thus, the equation of a line using the slope-intercept form is
[tex]y = mx+c[/tex]
m=2c=2[tex]y=2x+2[/tex]
Therefore, we conclude that the equation of a line using the slope-intercept form is
[tex]y=2x+2[/tex]Answer:

The students in a club are selling flowerpots to raise money. Each flowerpot sells for $21. Part A Write an expression that represents the total amount of money, in dollars, the students raise from selling x flowerpots. Enter the expression in the box provided. Enter only your expression.
Answers
Answer: y = 21x
Step-by-step explanation:
y in this expression represents the total amount of money, in dollars, the students raise from selling x flowerpots.
21 is the price of each flower pot.
x is the number of flower pots sold.
If for instance, they sold 30 flower pots, y(total amount in dollars) would be;
= 21x
= 21 * 30

vector u = <2,5> . Describe how you would use a graphical method to add vector u to vector v (shown in the graph). Then, write the resultant vector in the component form.
Answers
Answer:
Step-by-step explanation:
Draw vector u in standard position. To add u to v, shift u three units to the right and one unit up so its initial point coincides with the terminal point of v. Use a dotted line to depict the shifted vector u. Finally, draw the resulting vector with its initial point at the origin and endpoint at v + u. The component form of this resulting vector is <5, -4>.

Step-by-step explanation:

16m and 15w
1 tray of corn muffins and 4 trays of bran muffins = $11
16 - 4 = 12
15 - 3 = 12
12 - 8 = 4
12 - 12 = 0
b = $2
c = $3
c = 3 x 1 = 3
b = 2 x 4 = 8
3 + 8 = 11
-----------------------------------------------------------------------------------------------------------------
2 trays of corn muffins and 3 trays of bran muffins = $12
c = 4m + 3w
b = 2m + 3w
16 - 8 = 8
15 - 6 = 9
8 - 6 = 2
9 - 9 = 0
b = $2
c = $3
c = 3 x 2 = 6
b = 2 x 3 = 6
6 + 6 = 12

The marked angle GEF is 25
Step-by-step explanation:
Here, we want to calculate the value of the marked angle
Mathematically, a diagram should do justice to this
Please check the attachment for the diagram
The theorem we want to use is that the sum of opposite interior angles equals the exterior angle
Thus, mathematically;
2x + 1 + x + 19 = 6x + 2
3x + 20 = 6x + 2
6x-3x = 20-2
3x = 18
x = 18/3
x = 6
The angle marked GEF is x + 19
That will be 6 + 19 = 25
