X^2 + 2x = -1......take half of ur x term (2x), and square it. So we take half of 2, which is 1, and square it....1^2 = 1....so u would add 1 to both sides
7/8 / 2/7 =
7/8 * 7/2 = 49/16 = 3 1/16
she can make 3 shirts
The common difference in this sequence is -16 because each number decreases by 16 from the last
Answer:
1) solve x+1/x = 5
2) solve x³+1/x³
substitute x = 1/4 into the expression
Answer:
y=-5/3x+13.
Step-by-step explanation:
As a line that is perpendicular to anoher line has a slope that is the negative reciprocal of the line's original slope, we know that the slope of our new line is -5/3. As it passes point (12, -7), we can use the point slope formula which is y-y1=m(x-x1). So plug in, y+7=-5/3(x-12) and that gives us y+7=-5/3x+20 which gives our final answer of y=-5/3x+13.
