Answer: y=-4x+5
Step-by-step explanation:
9 is a parallelogram because parallelograms have parallel sides. and for 10 set 7x+3=3x+35 because its a rectangle and the side lengths are equal. solve to get
4x=32
x=8
x=x, so plug in 8for x for bc=2x+5
16+5=21
then plug in x to both equations just in case (ab and dc)
i got 59 and 59)
so 59 and 21 are the side lengths, so now use that calculator for the Pythagorean theorem.62.63 about.cuz its a right triangle.
Answer:
○ The graph of y = -2x² + 3 opens downward and is shifted up.
Step-by-step explanation:
According to the Quadratic Equation, <em>y = Ax² + Bx + C</em>, <em>C</em><em> </em>acts<em> </em>like a y-intercept, and in this case, since both graphs shift up [because both are positive values], we do not pay attention to those. Now, we come over to our <em>A</em>, which makes a BIG difference because both graphs open in opposite directions [one negative, one positive]. With this being stated, we have our answer.
