Answer:
She used 3/4 meters of ribbon.
Step-by-step explanation:
2 1/4 divided by 3.
2 1/4= 9/4
9/4 divided by 3
9/4*1/3
9/12
3/4 meters
Answer:
40
Step-by-step explanation:
by using similar triangles;
27/24=45/x
x=45x24/27=40
The function is y=f(x)=-2x-3
the graph of this function are all pairs (x, y)=(x, f(x))=(x, -2x-3)
the y-intercept of a graph of a function, is the point where the graph cuts the y-axis, which happens at x=0.
at x=0, f(x)=f(0)=-2*0-3=-3
the x-intercept(s) of the graph, are the point(s) where the graph intersects the x-axis. At those points, the y-coordinate is 0.
so the x-intercept(s) are points of the form (x, 0)
now,
(x, 0)=(x, -2x-3)
0=-2x-3
2x=-3
x=-3/2
Answer:
x-intercept: (-3/2, 0)
y-intercept: (0, )
The statement that is not true is
B. Perpendicular lines never intersect at right angles.
The definition of perpendicular lines is that they will intersect each other at 90 degree angles.
If this is an equation then write:
x-2=0
x=2
3x+3=0
x=-1
so smaller solution is x= -1 and larger is x=2
