Stuart wants to find the value of 3 3/4 -2 1/3 Before Stuart can subtract, he needs to rewrite both fractions with a common denominator. Drag a number or expression into each box to show how to write equivalent fractions so the new fractions have a common denominator.
Answer:
1 21/50
Step-by-step explanation:
3 3/4 = (3/4 x 4/4) = 3 9/12
2 1/3 = (1/3 x 3/3) = 2 4/12
3 9/12 - 2 4/12 = 1 21/50
Simplify the fraction below.
35/4
Answer:
8 3/4
Step-by-step explanation:
find the greatest common factor of 35 and 4, which is 1. Then divide both 35 and 4 by the greatest common factor to get the following simplified fraction: 35/4
If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. You could convert it into a whole number or mixed number fraction. Which would now be 8 3/4

1. The graph of y = f(x) is a parabola whose vertex is at (1, -2). The graph of y = f(x - 3) is also a parabola. Where is the vertex of the graph of y = f(x-3)? Write your answer as an ordered pair.
2. The graph of has the line as an axis of symmetry. The graph also passes through the point. Find another point that must lie on the graph of y = f(x).
3. The graph of y = f(x) is shown in the first picture in red. Find the equation that corresponds to the blue graph.
Enter your answer in the form "y = …".
4. The graph of y = h(x) is shown in red in the second picture. Compute h(h(7)).
(Assume grid lines are spaced 1 unit apart.)
5. In the third picture is a portion of the graph of a function, y=u(x):
What is the exact value of u(-2.72)+u(-0.81)+u(0.81)+u(2.72)?
Answer:
Q1The graph of y = f(x), has vertex at (1, -2)
The vertex of a function f(x - 3) is going to be:
(1 - 3, -2) = (-2, -2)Q2The graph of y = f(x) has the line x = 5 as an axis of symmetry. The graph also passes through the point (8,-7). Find another point that must lie on the graph of y = f(x).The axis of symmetry is at the same distance from the symmetric points.
x = 5 is a vertical line. The point (8, -7) is 3 units to the right. So the mirror point will be 3 units to the left and have same y-coordinate: x = 5 - 3 = 2
The point is (2, -7)
Q3The graph in blue is the translation of the red to the left by 2 units.
So the equation is:
y = f(x + 2)Q4y = h(x) is graphed
h(7) = 5h(h(7)) = h(5) = -1Q5The graph of the function y = u(x) given
This is a odd function.
The coordinates of u(x) and u(-x) add to zero because u(-x) = -u(x)
Therefore:
u(-2.72) + u(-0.81) + u(0.81) + u(2.72) = [u(-2.72) + u(2.72)] + [u(-0.81) + u(0.81)] = 0 + 0 = 0I Need Help With No. 5

Please help this is worth 15 points! Solve in y=mx+b from!
Answer:
The coordinates of every point on the line will solve the equation if you substitute them in the equation for x and y. The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept
