1. Triangle ABC is congruent to triangle EDF. So, Kiran knows that there is a sequence of rigid motions that takes ABC to EDF.
Please answer as soon as possible thank you!

Select all true statements after the transformations:
a. Angle A coincides with angle F.
b. Angle B coincides with angle D.
c. Segment AC coincides with segment EF.
d. Segment BC coincides with segment ED.​
e. Segment AB coincides with segment ED.

Answers

Answer: B.

C.

E.

Step-by-step explanation:

The true statements after the transformation, given that triangles ABC and EDF are congruent are: statements B, C, and E.

Recall what congruent triangles share in common:

If two triangles are congruent, all three sides of one triangle will be congruent to all corresponding three sides in the other triangle.If two triangles are congruent, all three angles of one triangle will be congruent to all corresponding three angles in the other triangle.

Thus, if triangle ABC is congruent to triangle EDF, then Kiran will know that after the transformation:

<A will coincides with angle E<B will coincides with angle D<C will coincides with F

Segment AC will coincides with EF, AB to ED, as well as BC to DF.

Therefore, the true statements after the transformation, given that triangles ABC and EDF are congruent are: statements B, C, and E.

Solve for x by factoring

X^2+4x-21=0

There are multiple answers

Answers

Answer:

[tex]x=3,-7[/tex]

Step-by-step explanation:

We can solve for x by using [tex]\frac{-b\pm\sqrt{b^{2} -4ac} }{2a}[/tex]

By applying this on the quadratic equation, we get:

[tex]x=\frac{-4\pm\sqrt{4^{2}+84} }{2}[/tex]

Which simplifies to:

[tex]x=\frac{-4\pm10}{2}[/tex]

[tex]\therefore x=3,-7[/tex]

The cost of a gym membership is $25 per month. There is an initial fee of $40

Answers

Answer:

y = 25x + 40

Step-by-step explanation:

Using the formula, y = mx + b we can find out what this equation would be.

m = the rate of change/slope

b = the y- intercept

25 per month is telling us that this is the rate of change.

Since the $40 is only paid once, you can tell that this is the y intercept.

The equation will look like:

y = 25x + 40

On a graph it would look like:

Let the total cost of a gym membership be y, with the number of months as x.

The total cost would be 40 dollars, the initial fee, plus 25 times the number of months (x).

y = 40 + 25x
