7) If x-2 is a factor of P(x)= x^2-5x+a then find the value of a
2
3
4
6
please answer
Answer:
a = 6
Step-by-step explanation:
Given that (x - 2) is a factor of P(x) , then P(2) = 0 , that is
P(2) = 2² - 5(2) + a = 0 , so
4 - 10 + a = 0
- 6 + a = 0 ( add 6 to both sides )
a = 6
Solve for x:
( x - 2 ) ( x + 3 ) ( 2x - 7 ) = 0
Answer:
x=2, x=-3, or x=3.5
Step-by-step explanation:
Make them all in 3 equations equal to 0. The number of brackets, the number of equations.

9514 1404 393
Answer:
P = 250 +50t
Step-by-step explanation:
We are given two pairs of time and price:
(t, P) = (0, 250) and (5, 500)
We can put these into the 2-point form of the equation for a line:
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
P = (500 -250)/(5 -0)(t -0) +250
P = 250/5t +250
P = 50t +250 . . . . Madelyin's cost equation

Which linear inequality is represented by the graph?
O y > 2x + 2
O yz 2x + 1
Oy> 2x + 1
O y z 2x+2
By analyzing the graph, we will see that the inequality is:
y > 2x + 1
How to know the inequality represented by the graph?
From a first look, we can see two things.
The line is a dashed line, so the values on the line are not solutions.The shaded region is above that line.From that we can conclude that the inequality is something like:
y > line.
To find the equation of the line, we can look at the graph.
We can see that it intercepts the y-axis at y = 1, and for each increase of one unit in the x-axis increases 2 units on the y-axis, so the line is:
2x + 1
Then the inequality is:
y > 2x + 1.

Jim mowed 5/9 of a lawn. Sarah mowed 1/3 of the lawn. What fraction of the lawn remained to be mowed?
Answer:
1/9
Step-by-step explanation:
Because 1/3 is the same as 3/9, 5/9 + 3/9 = 8/9. so then 9/9 - 8/9 = 1/9. Giving them 1/9 of the lawn remained to be mowed.
A rental car company is running two specials. Customers can pay $50 to rent a compact car
for the first day plus $6 for each additional day, or they can rent the same car for $20 the
first day and $12 for every additional day beyond that. Nora notices that, given the number
of additional days she wants to rent the car for, the two specials are equivalent. How many
additional days does Nora want?
Write a system of equations, graph them, and type the solution
Answer:
After 5 additional days it will be equal
Step-by-step explanation:
1st special: 6x + 50
2nd special: 12x + 20
6x + 50 = 12x + 20
Subtract 20 from both sides;
6x + 30 = 12x
Subtract 6x from both sides;
30 = 6x
Divide both sides by 6;
x = 5

the sum of the interior angles in a pentagon
Answer:
540°
Step-by-step explanation:
When you have a polygon (shape with 3+ sides), you can split the shape into the lowest number of triangles and use that to calculate the interior angles of the shape. Thus works because triangles have angles that always add up to 180°
A Pentagon can be split into 3 triangles minimum, which means you have 180 + 180 + 180. Or...
180 x 3 = 540

Select all angles that MUST be supplementary to 9
Answer:
Angles supplementary to angle 9 = Angle 10, 7, 5, 1, 4, 3, 15, 12, 24, 22, 20, 19, and angle 16.
Step-by-step explanation:
Use the vertical, and corresponding angles theorem to find congruent angles.
Look for linear pairs (adjacent(next to each other, or share a side) angles that make 180° or a straight angle) from the corresponding angles.
Something is supplementary if it adds to 180 degrees.
The vertical angles theorem states that pairs of opposite angles made by interesecting lines are congruent.
The corresponding angles theorem states that corresponding or angles relative to the same position are congruent if the transversal crosses at least 2 parallel lines.
