Answer:
7q
Step-by-step explanation:
that is the procedure above
2/3 lb. - 1/3 lb. = 1/3 lb.
check: 1/3 lb. + 1/3 lb. = 2/3lb
ANSWER 》1/3 lb. MORE
The intersection point is only one. Then the equation of the line is tangent to the circle at point (1, -2).
<h3>What is a circle?</h3>
It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
Prove algebraically that the straight line with equation x = 2y + 5 is a tangent to the circle with equation x² + y² = 5.
x = 2y + 5 ...1
x² + y² = 5 ...2
If the intersection of the point of the circle and line is one. Then the line is tangent to the circle.
Then from equations 1 and 2, we have
(2y + 5)² + y² = 5
4y² + 25 + 20y + y² - 5 = 0
5y² + 20y + 20 = 0
5y² + 10y + 10y + 20 = 0
5y (y + 2) + 10(y + 2) = 0
(5y + 10)(y + 2) = 0
y = -2, -2
Then the value of y is unique then the value of x will be unique.
The value of x will be
x = 2(-2) + 5
x = -4 + 5
x = 1
The intersection point is only one. Then the equation of the line is tangent to the circle at point (1, -2).

h = a/4
Step-by-step explanation:
h = a/4 has already been solved for h; there is nothing left to do here.
Answer:
He did 2 divide by 2.50 instead of 2.50 divide by 2 like x and y y=kx
Step-by-step explanation:
2.50 ➗2 = 1.25 per pound
1 lbs =1.25
