if p(x)=x*2-1 and q(x)=5(x-1),which expression is equivalent to (p-q)(x)?
Answer:
[tex](p - q)(x) = (x -1) (x - 4)[/tex]
Step-by-step explanation:
Given
[tex]p(x) = x^2 - 1[/tex]
[tex]q(x) = 5(x - 1)[/tex]
Required
(p - q)(x)
This is represented as:
[tex](p - q)(x) = p(x) - q(x)[/tex]
[tex](p - q)(x) = x^2 - 1 - 5(x - 1)[/tex]
[tex](p - q)(x) = x^2 - 1 - 5x + 5[/tex]
Collec like terms
[tex](p - q)(x) = x^2 - 5x + 5 - 1[/tex]
[tex](p - q)(x) = x^2 - 5x + 4[/tex]
Expand
[tex](p - q)(x) = x^2 -4x - x + 4[/tex]
Factorize
[tex](p - q)(x) = x(x -4) - 1(x - 4)[/tex]
[tex](p - q)(x) = (x -1) (x - 4)[/tex]

Step-by-step explanation:
Let the chocolate chip cookies = x
Let the jumbo popcorn = y
Julie
y + 2x = 5
Marvin
y + 4x = 6 Subtract
-2x = - 1 The y's disappear. You are left with 1 dollar (negative). Divide by - 2
-2x/-2 = - 1 / -2
x = 1/2
x = 0.5 or 50c
Each cookie costs 50c

A 10-ounce container of chocolate chips can be used to make 4 desserts.
Each dessert has the same number of chocolate chips.
Which equation shows how to find the number of ounces in each dessert?
A number line going from 0 to 10 in increments of 1.
10÷4=104 ounces
4÷10=104 ounces
10÷4=410 ounce
4÷10=410 ounce
Answer:
So equation will be 4x = 10
A 10 ounce container of chocolate chips can be used to make 4 desserts.
Each desert has the same number of chocolate chips
Let number of chocolate chips in each dessert = x ounce
Therefore, chocolate chips in 4 deserts = 4x and total chocolate chips is = 10 ounce.
So equation will be 4x = 10

Answer: 46
Step-by-step explanation:
Let the 3 consecutive even numbers be x, (x-2) and (x+2) respectively.
According to the question,
x + (x - 2) + (x + 2) = 132
or, x + x - 2 + x + 2 = 132
or, 3x = 132
or, x = 132 ÷ 3
or, x = 44
So, first even number = 44
Required third number = 44 + 2
= 46

solve using elimination method. show work -3×+4y=1 -4×+5y=-2
Answer:
Multiply the first equation by 4 and the second equation by -3:
-12x + 16y = 4
12x - 15y = -6
‣ Add the equations:
‣ Solve for y:
y = -2
‣ Substituting y = -2 into the first equation, we get:
-12x + 16 ⋅ (-2) = 4
‣ Solve for x:
x = -3
‣ Solution:
x = -3, y = -2)

Identify the angles , solve for x
Answer:
Consecutive interior angles ; x = 20
Step-by-step explanation:
These are known as consecutive interior angles. This means they are equal to each other. Knowing this, we can set up an equation to solve for x.
4x - 30 = 2x + 10
2x - 30 = 10
2x = 40
x = 20
