Mathematics
1 answer:
Morgarella [4.7K]3 years ago
4 0

Answer:

3x² - 14x + 14

Step-by-step explanation:

Given

3(x - 2)² - 2(x - 1) ← expand (x - 2)² using FOIL

= 3(x² - 4x + 4) - 2(x - 1) ← distribute both parenthesis

= 3x² - 12x + 12 - 2x + 2 ← collect like terms

= 3x² - 14x + 14

Evaluate 5x^2-3x+2 for x=-3
zhuklara [117]
Alright, so in PEMDAS, we first do exponents. 3^2=9, and we then have 5(9)-3(3)+2. After that, we have multiplication, where we have 5*9 =45 and 3*3=9, resulting in 45-9+2 and eventually 38

Find the equation of the line parallel to the graph of 7x-3y=21 that has an x-intercept of -1.
zhuklara [117]
To start this, you would have to get y by itself to have an equation you can graph. Start by subtracting 7x from both sides. 
-3y= -7x+21
Next, divide both sides by -3
y = 7/3x + 7
A parallel line would have the same slope of 7/3x. Since you need to have an intercept of -1 the equation would be y = 7/3x -1
