Factor the following:
x^2 - 4 x + 3
The factors of 3 that sum to -4 are -1 and -3. So, x^2 - 4 x + 3 = (x - 1) (x - 3):
Answer: (x - 1) (x - 3)

Answer:

$x = \frac{1}{2}$

$x = -\frac{5}{2}$

Step-by-step explanation:

Solve Using the Quadratic Formula

4x^2 + 8x − 5 = 0

Use the quadratic formula to find the solutions.

−b ± √b^2 − 4 (ac)

-------------------------

Substitute the values a = 4, b = 8, and c = −5 into the quadratic formula and solve for x.

−8 ± √82 − 4 ⋅ (4 ⋅ −5)

-------------------------

2 ⋅ 4

Simplify the numerator.

Raise 8 to the p ower of 2.

−8 ± √64 − 4 ⋅ 4 ⋅ −5

x= ---------------------------

2 ⋅ 4

Multiply −4 by 4.

−8 ± √64 − 16 ⋅ −5

x = -------------------------

2 ⋅ 4

Multiply −16 by −5.

−8 ± √64 + 80

x = -------------------

2 ⋅ 4

Add 64 and 80.

−8 ± √144

x = --------------

2 ⋅ 4

Rewrite 144 as 12^2.

−8 ± √122

x = ------------

2 ⋅ 4

Pull terms out from under the radical, assuming positive real numbers.

multiply 2 by 4

−8 ± 12

x= ------------

simplify

−2 ± 3

x= ---------

The final answer is the combination of both solutions.

x= 1/2, -5/2

What is the y-intercept of the line y+11= -2(x+5)?

poizon [28]

Answer:

y-intercept is (0, -21)

Step-by-step explanation:

For y-intercept, x = 0:

${ \sf{y + 11 = - 2(0 + 5)}} \\ { \sf{y + 11 = - 10}} \\ { \sf{y = - 21}}$

Wheel world sold 875 cars last year if the sales this year are 120% of sales last year how many cars will they sell this year

inn [45]

okay so first you wanna turn that 120% into a decimal and the decimal form of that would be 1.2 or 1.20

Secondly you want to multiply 875 by the 1.2

875*1.2 = 1050

So if they sell 120% of last years sales they will sell 1050 cars this year.

Hope this helped :)
