Answer:
68 mph
Step-by-step explanation:
Mph=miles ÷ time
Mph=204 ÷ 3
One way is subsitute
I like solving
so
what you do is this
add the equaitons to gether to eliminate x
2y=x+5
<u>3y=-x-3 +</u>
5y=0x+2
5y=2
y=2/5
sub back
2y=x+5
2(2/5)=x+5
4/5=x+5
minus 5
4/5-25/5=x
-21/5=x
the point is (x,y) or
(-21/5,2/5)
aprox
(-4.2,0.4)
I think they wanted you to read the garph you should have attached and guess the answer
the closes one is
hmm, x=-3
and y=1
so then D is the answer
Range = 60-0=60
Median = 30
Interquartile Range = 35
It has 2 solutions <span><span>
1.y = -1 </span><span><span>
2.y = 4/3 = 1.333</span></span></span>
Answer:
The statement is false.
Step-by-step explanation:
A parallelogram is a figure of four sides, such that opposite sides are parallel
A rectangle is a four-sided figure such that all internal angles are 90°
Here, the statement is:
"A rectangle is sometimes a parallelogram but a parallelogram is always a
rectangle."
Here if we found a parallelogram that is not a rectangle, then that is enough to prove that the statement is false.
The counterexample is a rhombus, which is a parallelogram that has two internal angles smaller than 90° and two internal angles larger than 90°, then this parallelogram is not a rectangle, then the statement is false.
The correct statement would be:
"A parallelogram is sometimes a rectangle, but a rectangle is always a parallelogram"
