Answer:
( 
, 0 )
Step-by-step explanation:
To find the x- intercepts let y = 0, that is
2x² + 3x - 2 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × - 2 = - 4 and sum = + 3
The factors are + 4 and - 1
Use these factors to split the x- term
2x² + 4x - x - 2 = 0 ( factor the first/second and third/fourth terms )
2x(x + 2) - 1 (x + 2) ← factor out (x + 2) from each term
(x + 2)(2x - 1) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
2x - 1 = 0 ⇒ 2x = 1 ⇒ x =
The x- intercepts are (- 2, 0 ), ( , 0 )
Answer:
Step-by-step explanation:
Let the number be y & reciprocal simply means inverse of the number
4×1/y=2×1/8 solving for y
4/y=2/8; y = 16
Answer:
-15 and 9
Step-by-step explanation:
-3 - 12 = -15
-3 + 12 = 9
Answer:
y</= 2
Step-by-step explanation:
9 + 1 = 10
9 + 2 < 10
y = anything < 2

Explanation: This question's it's about the order of operations. It stands for p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract. It can also go left to right. (PEMDAS)
1. -4(3-1)+2
Do parenthesis first.
Then do multiply left to right.
Add left to right.
*Answer should be have negative sign.*
Answer: → 
______________________________________________________
2. 3⋅[(30−8)÷2+2]
Do parenthesis first.
Then divide left to right.
Add left to right.
Multiply left to right.
*Answer should be have positive sign.*
Answer: →
