Answer:
Step-by-step explanation:
The product of two numbers is greater than one of the multiples if the other multiple is greater than 1.
a)
- 7/5 × 1/3 > 1/3 as 7/5 > 1 ⇒ yes
b)
- 3/4 × 2/9 < 2/9 as 3/4 < 1 ⇒ no
c)
- 4/3 × 2/9 > 2/9 as 4/3 > 1 ⇒ no
d)
- 5/7 × 1/3 < 1/3 as 5/7 < 1 ⇒ yes
Answer:
b
Step-by-step explanation:
The answer to the equation. is 2
Answer:
x = 125
Step-by-step explanation:
all of the angles in a triangle must add up to 180, so 25 + 30 + x = 180. you can subtract 25 and 30 from both sides and you are left with x = 125.

Solution:
y = 2x^2 - 3 ---- equation 1
y = 3x - 1 ------equation 2
Then we get,
2x^2 - 3 = 3x - 1
Now, simplifying the equation, we get
2x^2 - 3x - 3 + 1 = 0
2x^2 - 3x - 2 = 0
After factoring the equation, we get
(2x+1)(x-2) = 0
So, this means
(2x+1) = 0 and (x-2) = 0
From this, we get
x = -1/2 and x = 2
Putting values of x = -1/2 in equation 2
y = 3(-1/2) - 1
y = -2.5
Now, putting value of x = 2 in equation 2
y = 3(2) -1
y = 5
