Step-by-step explanation:
The discriminant of ax^2+bx+c=0 is b^2-4ac, in this case
4^2-4(2)10
16-80
-64
Since -64<0 there are two imaginary (or ‘complex’) solutions.
Note: if d=0, there is one real solution. if d>0, there are two real solutions.
If ƒ(x ) = x 2 + 1 and g(x ) = 3x + 1, find 2 · ƒ(4).

Evaluate: 4 + 13 - 2^2
Answer: 13
Step-by-step explanation:
According to pemdas (parenthesis, exponents, multiplication and divisions (from left to right)x aditioncand subtraction (left to right)
So first you would do 2^2 which 4
So now the equation would be 4+13-4
Positive 4 and negative 4 cancel out
The answer is 12
Can someone help me with this please
Answer:
Step-by-step explanation:
9) In parallelogram, adjacent angles are supplementary
14x - 4 + 86 = 180
14x = 180 - 86 + 4
14x = 98
x = 98/14
x = 7
10) In parallelogram, opposite angles are congruent.
6x + 4 = 64
6x = 64 - 4
6x = 60
x = 60/6
x = 10
11) In parallelogram, opposite sides are congruent.
3x + 4 = 2x + 10
3x -2x + 4 = 10
x + 4 = 10
x = 10-4
x = 6

Find the discriminant and determine the number of real roots for each equation. Show steps.
-3p^2 - 2p = 0
Answer:
discriminant: 4; number of real roots: 2
Step-by-step explanation:
The coefficients a, b and c of this quadratic are {-3, -2, 0}.
Thus, the discriminant b^2 - 4ac is (-2)^2 - 4(-3)(0), or 4.
Because the discriminant is positive, this quadratic has two real, unequal roots.
-3p^2 - 2p can be factored as follows: -p(3p + 2). If we set this expression equal to zero, we can find the roots: {-2/3, 0}
Al and Tom are painting a shed. Working alone, Al can paint the shed in 2 hrs. Together they can paint the shed in 1.5 hours. How long would it take Tom to paint the shed on his own?
Answer:
6 hours.
Step-by-step explanation:
The formula sort of has to be invented.
Al
rate = 1 shed / 2 hours
Tom
rate = 1 shed / x hours.
Together.
rate = 1 shed / 1.5 hours.
Equation
1 shed / 2 hours + 1 shed / x hours = 1 shed / 1.5 hours.
1/2 + 1/x = 1/1.5 Put the fractions over a common denominator.
(x + 2) / 2x = 1 / 1.5 Cross Multiply
1.5(x + 2) = 2x Remove the Brackets.
1.5x + 3 = 2x Subtract 1.5x from both sides
3 = 2x - 1.5x
3 = 0.5x Multiply both sides by 2
6 = x
It would take Al 6 hours to do the shed on his own.

The meaning to have a negative change is, it is decreasing over time.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
We have to explain the meaning to have a negative change.
Hence, We get;
A positive rate of change means that the quantity you are measuring is increasing over time, and a negative rate of change means that it is decreasing over time.
Thus, The meaning to have a negative change is, it is decreasing over time.

A sports store has 468 golf balls. They will be put into boxes that hold 18 balls each. What is the minimum number of boxes needed for all of the golf balls?
The minimum number of boxes needed for all of the golf balls is 26.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of golf balls = 468
Number of golf balls in one box = 18
The number of boxes.
= 468 ÷ 18
