Answer:
Step-by-step explanation:
1) 6 and -5
x₁ + x₂ = 6 +(-5) = 1
x₁* x₂ = 6*(-5) = -30
x² -(x₁ + x₂)x + (x₁* x₂)=0
x² - x - 30 = 0
2) 4 and 7
x₁ + x₂ =4 + 7 = 11
x₁* x₂ = 4*7 = 28
x² - 11x + 28 = 0
3) 1 and -10
x₁ + x₂ = 1 +(-10) = -9
x₁* x₂ = 1*(-10) = -10
x² - 9x - 10 = 0
4) -9 and 0
x₁ + x₂ = -9 + 0 = -9
x₁* x₂ = 0
x² - (-9)x = 0
x² + 9x = 0
5)2 and 6
x₁ + x₂ = 2 + 6 = 8
x₁* x₂ = 2*6 = 12
x² -8x + 12 = 0
8) 2 +√3 and 2 - √3
x₁ + x₂ = 2+ √3 + 2 - √3 = 4
x₁* x₂ = (2 + √3)(2 - √3) = 2² - (√3)² 4 - 3 = 1
x² - 4x + 1 = 0
Answer:
Should be (-21/4) (2/3) = -42/12 = -21/6
So answer is
Esmerelda did not use the reciprocal of the divisor.
Step-by-step explanation:
Answer:
A) 8/17
Step-by-step explanation:
cos = adj/hyp
In this problem the unknown angle has a hypotenuse pf 17, 15 as opposite, and 8 as adjacent
V = 8, because it can’t be simplified any further.
Answer:
y = 4/3x - 3
Step-by-step explanation:
Use the slope intercept equation, y = mx + b, where m is the slope and b is the y intercept:
Plug in the point given and the slope to find b:
y = mx + b
1 = 4/3(3) + b
1 = 4 + b
-3 = b
Then, plug this and the slope into the equation:
y = 4/3x - 3 will be the equation
