Answer: (-3/4)/=-3/4•4/3=-12/12=-1 = = 0
Step-by-step explanation:
Unary minus: -3
4
Multiple: the result of step No. 3 * 4
3
= -3
4
* 4
3
= -3 · 4
4 · 3
= -12
12
= -1 · 12
1 · 12
= -1
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(-12, 12) = 12.
In words - minus three quarter multiplied by four thirds = minus one.
Compare: (the result of step No. 4) = (-1)
Unary minus: -12
12
= -1
Compare: (the result of step No. 6) = (-1)
Compare: (-1)
Answer:
y = 3
Step-by-step explanation:
2x - 5y = 1 ----------------(i)
-3x + 2y = -18 ---------------(ii)
(i) * 3 6x - 15y = 3
(ii)*2 <u> -6x + 4y = -36</u>
add==> -11y = -33
y = -33/-11
y = 3
Answer:
A is correct
Step-by-step explanation:
You have to find the rate of change for each one.
Divide the price with the amount
Hope this helps!
Answer:
the answer is A
Step-by-step explanation:
78 is acute angle because it is less than 90 degrees. A is an acute angle so thats the answer
The solution is x = 4 and y = -1
Step-by-step explanation:
The system of equation is:
- y =
x - 3 - y = x - 5
To solve it using the elimination method do that
∵ y = x - 3 ⇒ (1)
∵ y = x - 5 ⇒ (2)
- Subtract equation (1) from equation (2) to eliminate y
∵ y - y = (x - x) - 5 - (-3)
- Remember (-)(-) = (+)
∴ 0 = x - 5 + 3
∴ 0 = x - 2
- Add 2 to both sides
∴ 2 = x
- Multiply both sides by 2
∴ 4 = x
∴ x = 4
- Substitute the value of x in equation (1) or (2) to find y
∵ y = 4 - 5
∴ y = -1
The solution is x = 4 and y = -1
