Step-by-step explanation:
1) [tex]y = x^2 + 4x + 3[/tex]
Lets split the middle term.
[tex]=> y = x^2 + 3x + x + 3[/tex]
[tex]=> y = x(x+3) + 1(x + 3)[/tex]
[tex]=> y = (x+1)(x+3)[/tex]
∴ [tex]x = -3 , -1[/tex]
2) [tex]y = 8x^2 - 22x + 5[/tex]
Lets split the middle term.
[tex]=> y = 8x^2 - 20x - 2x + 5[/tex]
[tex]=> y = 4x(2x - 5) - 1(2x - 5)[/tex]
[tex]=> y = (2x - 5)(4x - 1)[/tex]
∴ [tex]x =\frac{1}{4} , \frac{5}{2}[/tex]
3) [tex]y = x^2 - 5x[/tex]
[tex]=> y = x(x - 5)[/tex]
∴ [tex]x = 0 , 5[/tex]
4) [tex]y = 12x^2 + 18x[/tex]
[tex]=> y = 6x(2x + 3)[/tex]
∴ [tex]x = \frac{-3}{2} , 0[/tex]
5) [tex]y = x^2 - 7x + 12[/tex]
Lets split the middle term.
[tex]=> y = x^2 -3x - 4x + 12[/tex]
[tex]=> y = x(x - 3) - 4(x - 3)[/tex]
[tex]=> y = (x - 3)(x - 4)[/tex]
∴ [tex]x = 3,4[/tex]
6) [tex]y = 3x^2 + 10x + 8[/tex]
Lets split the middle term.
[tex]=> y = 3x^2 + 6x + 4x + 8[/tex]
[tex]=> y = 3x(x + 2) + 4(x + 2)[/tex]
[tex]=> y = (x + 2)(3x + 4)[/tex]
∴ [tex]x = -2 , \frac{-4}{3}[/tex]
7) [tex]y = x^2 - 4x - 45[/tex]
Lets split the middle term.
[tex]=> y = x^2 - 9x + 5x - 45[/tex]
[tex]=> y = x(x - 9) + 5(x - 9)[/tex]
[tex]=> y = (x - 9)(x + 5)[/tex]
∴ [tex]x = -5 , 9[/tex]

Answer:
x = 13.6 in
Step-by-step explanation:
The arc x is calculated as
x = circumference of circle × fraction of circle
= 2πr × [tex]\frac{0.8}{2\pi }[/tex] ( cancel the 2π on numerator/ denominator )
= 17 × 0.8
= 13.6 in

-2x/3 + 11 = 14 please help me its not letting me put stuff I want
Answer:
x = -4 1/2
Step-by-step explanation:
-2x/3 + 11 = 14
subtract 11 from each side of the equation:
-2x/3 = 3
multiply both sides by 3:
-2x = 9
divide both sides by -2:
x = -4 1/2

Right now Seth’s age is 4/5 the age of his brother Eric. Twenty-one years ago, Eric was twice as old as Seth. What are their ages now?
Answer: We are told that 21 years ago, Eric was twice as old as Seth. So, Eric was 2{(4/5)x-21} years old 21 years ago (just multiply Seth's age 21 years ago by 2).

Choose the correct solution for the inequality:
-4x + 5 >-5
A: x < 2.5
B: X > 2.5
C: X <-2.5
D: X > -2.5
Answer:
A
Step-by-step explanation:
We have -4x > -10, so 4x < 10
Answer:
A. x < 2.5
Step-by-step explanation:
you subtract 5 on both sides
then you get -4x > -10.
then you divide -4 on both sides
and you get x<2.5

Find the slope of the line through the points (11, -18) & (19, 16)
Answer:
m = 17/4
Step-by-step explanation:
(11, -18) & (19, 16)
Slope Formula:
m=(y2-y1)/(x2-x1)
m=(16 + 18)/(19-11)
m=(34)/8
m = 17/4

Please help me answer the question below, I will give brainliest thing to whoever helps and gets it correct, thank you!
Answer:
y = 1/2 x + 5
Step-by-step explanation:
slope (m) = (y'-y) / (x'-x)
(y-6)/(x-2) = 1/2
y - 6 = 1/2 x - 1
y = 1/2 x + 5
