Answer: x=7, y=-2
umm do you need to show work?
Answer:
x= 2, 1/2
Step-by-step explanation:
x= b±√b²-4ac/2a
x = [5±√(-5)²-4·(2·2)]/2·2
x = (5±3)/4
x= 2, 1/2
He sold 3 tickets
It makes sense cus
3+5 equals 8 and 8
times 5 equals 40
Answer:
(3/2, 7/2)
Step-by-step explanation:
Given the system of equations;
y = 3x/2 + 5/4..... 1
-2x + 8y = 25 .... 2
Substitute equation 1 into 2;
From 2;
-2x + 8y = 25
-2x + 8(3x/2 + 5/4) = 25
-2x + 12x + 10 = 25
10x = 25 - 10
10x = 15
x = 15/10
x = 3/2
Substitute x = 3/2 into equation 1
From 1;
y = 3x/2 + 5/4
y = 3/2(3/2) + 5/4
y = 9/4 + 5/4
y = 14/4
y = 7/2
Hence the solution to the equation is (x, y) = (3/2, 7/2)
Answer:
a = 2, b = - 6, c = 11
Step-by-step explanation:
The standard form of a quadratic equation is
ax² + bx + c = 0 : a ≠ 0
Compare the coefficients of the terms in standard form to
2x² - 6x + 11 = 0 ← in standard form
Thus a = 2, b = - 6 and c = 11
