Which of the following best describes the male and female reproductive structures of an angiosperm? Angiosperms produce male and female gametophytes, and the male gametophyte produces spores that fertilize eggs inside the female gametophyte.
Angiosperms produce flowers, inside which the male stamens hold the pollen and the female pistil holds the ovule.
Angiosperms produce male and female cones, and the pollen from a male cone fertilizes the egg inside a female cone.
Angiosperms produce sporangia, which release spores that develop into male flowers containing pollen and female flowers containing ovules.

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

r and t.

both are 64 degrees.

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
