Answer:
The correct option is;
On a coordinate plane, 2 straight lines are shown. The first solid line is horizontal to the y-axis at y = negative 1, Everything above the line is shaded. The second dashed line has a positive slope and goes through (0, negative 4) and (2, negative 2). Everything above and to the left of the line is shaded
Step-by-step explanation:
The inequality representing the first line is y ≥ -1
The inequality representing the second line is y > x + 4
Therefore, the first line is a solid horizontal line with the shaded region above the line
The second line is a line with a broken line with positive slope slope with the shaded region being above the line and to the left
The answer to this question is 2/3.
You would distribute, 300 times 80 is 2400 and -3x times 1x is -3x so the equation would be y=2400-3x
Answer:
two real, unequal roots
Step-by-step explanation:
y is definied as y = 3x - 1. Substitute 3x - 1 for y in xy = 9, obtaining:
x(3x - 1) = 9. Then:
3x^2 - x - 9 = 0. In this quadratic, the coefficients are a = 3, b = -1 and c = -9.
Calculating the discriminant b^2 - 4ac, we get (-1)^2 - 4(3)(-9), or 1 + 108, or 109. Because the discriminant is positive, we have two real, unequal roots.
Step-by-step explanation:
sqrt(-4) = sqrt(4×-1) = sqrt(4)×sqrt(-1) = 2i
