<h3>Answer:  C) 4/7</h3>

Explanation:

The given equation is in the form y = mx+b with slope m = -7/4

Take the negative reciprocal of this to get 4/7. We simply flip the fraction and the sign (from negative to positive).

Note that multiplying any original slope with its perpendicular counterpart, will always get you -1

(-7/4)*(4/7) = -1

This applies to lines that are not vertical and not horizontal.

Answer:

C.

Step-by-step explanation:

The slope of the given line is -7/4

Let the slope we want be m :

Then m * -7/4 = -1        ( as the slopes of perpendicular lines have  a product of -1)

m = -1 / -7/4

= 1 * 4/7

= 4/7.

Delvig [45]
<span>x(t)=2t
y(t)=t^2
A) (-4,4),
x(t)=2t=-4, t=-2
y(-2)=(-2)²=4 , True

</span>B) (-2,-4)
x(t)=2t=-2, t=-1
y(-1)=(-1)²=1 False. we have y=-4 

C) (0,0)
x(t)=2t=0, t=0
y(0)=(0)²=0   True 

D)(1,2)
x(t)=2t=1, t=1/2
y(1/2)=(1/2)²=1/4 False. we have y=2

E) (6,9)
(-2,-4)
x(t)=2t=6, t=3
y(3)=(3)²=9 True.     

Correct answers is A, C, E.

Math help please,,, thank u uwu!

Answer:

AC=BD

CAD=CBD

ACB=ADB

Step-by-step explanation:

You're essentially looking for anything of equal proportions. Obviously, your circle is split by several lines, and each side is symmetric. Since you know this, it's simply a matter of identifying one element then finding its symmetric match.

Follow the lines and trace the path with your finger for each question. If you do this, you'll see that AC=BD is an answer that involves a symmetric pair, because these two are equal distances and equal (but opposite) in placement.

Continuing with this method, keep track of the parts of the triangles you trace. With CAD=CBD, you trace across a hypotenuse, a leg, and a base in BOTH, making this true.

Continuing further with ACB=ADB, you trace across a hypotenuse, a leg, and a base with both AGAIN, making this true.

With AB=CD, this is obviously incorrect. You can't jump between points.
