the answer would be “given” because you always want to start off with it and finish the proof based on it.

The first statement in a formal proof is given.

What should always be the first statement in a formal proof?

Remember to always begin our proof with the given information, and complete our proof with what you set out to deliver. As long as you do that, utilize one reason at a time, and only utilize definitions, postulates, and different theorems for your reasons, your proofs will float like a mountain stream.

The most familiar form of explicit proof in high school geometry exists as a two-column proof that consists of five parts: the given, the proposition, the statement column, the reason column, and the diagram (if one exists given).

Therefore, the correct answer is option b) Given.

PLEASE HELP !!!!!!!! What is the equation of the directrix for the following parabola: -8(x-5)=(y+1)^2

a. y=-3
b. x=7
c. y=7
d. x=-3

Answers

Answer:

x=7

Step-by-step explanation:

The directrix of the equation is x=7

What is directrix of parabola?

The directrix of a parabola is a line that is perpendicular to the axis of the parabola. The directrix of the parabola helps in defining the parabola. A parabola represents the locus of a point which is equidistant from a fixed point called the focus and the fixed line called the directrix. The directrix and the focus are equidistant from the vertex of the parabola. Here we define the directrix for the standard equations of a parabola.

The directrix of the parabola y^2 = 4ax, having x-axis as its axis, passes through (-a, 0), and has the equation x + a = 0.The directrix of the parabola y^2 = -4ax, having x-axis, passes through (a, 0), and has the equation x - a = 0.The directrix of the parabola x^2 = 4ay, having y-axis as its axis, passes through (0, -a), and has the equation y + a = 0.The focus of the parabola x^2 = -4ay, having y-axis as its axis, passes through (0, a), and has the equation y - a = 0.

Given:

-8(x-5)=(y+1)²

Now, using the definition of directrix

x= 8/4 +5

x= 2+ 5

x= 7

1 point for each correct angle measure and 1 point for explaining or showing how you got your answer. Don’t forget to label your answers.

Answers

Answer:

C = 95°

D = 72°

F = 108°

Step-by-step explanation:

Opposite angles of an inscribed quadrilateral are supplementary. Inscribed angles are half the measure of the arc they subtend. (The latter statement can be used to prove the former one.)

Using these relations, we have .

 C = 180° -E = 180° -85° = 95°

 D = 144°/2 = 72°

 F = 180° -D = 180° -72° = 108°

Joe, Marty, and Sally all decide to buy a new car for $15,000. Each one decides to pay for their car in a different way. Compare each of their stories and decide who you think made the best decision when they bought their car.

Answers

Answer: 15 months

Step-by-step explanation: bc if you multiply 15 times the amount he is saving a month which is $1,000. you multiply them two together and get 15,000. (sorry if i over explained it)

A basketball is thrown upward from a height of 6 feet at an initial speed of 15 feet per second. As the basketball travels, Earth's gravity slows it down.

The height of an object dropped from a height of 6 feet is given by h(t)=−16t2+6.

The distance in feet traveled by an object at a constant speed of 15 feet per second is given by d(t)=15t.

These two functions can be combined to build a new function, f, that models the height of the basketball as a function of time in t seconds.

Which choice shows how to combine h and d to build f

Answers

Answer: f(t)=h(t)+d(t)

f(t)=-16t^2+15t+6

For this composite question you will need to divide the shape into two different shapes. The large rectangle is going to be 60 in square because of base times height and then you would need to find the square which would be 4 times 4 cause of base times height but because it’s a triable you divide by 3 so 16/2 would be 8 than you would add both shapes and get 68 in squared.

Answer:  The answer is -5

Step-by-step explanation:

4x - 3 = 6x + 7

-10 = 2x

-5 = x

Answer:

x = -5

Step-by-step explanation:

4x - 3 = 6x + 7

Add 3 to both sides to isolate the variable:

4x = 6x + 10

Subtract 6x from both sides to keep x on 1 side:

-2x = 10

Divide by -2 to have the base value of x:

x = -5

I did not get any zeros since the graph doesn’t cross the x axis, meaning that there are no rational zeros

However, here is the method u can use to find the zeros lol


You can use the quadratic formula in order to get the zeros

This is the equation therefore use these values
ax^2+bx+c=0

A=1
B= -5

Keisha took out a loan for 10,500 and was charged simple interest at an annual rate of 8.8%. The total interest she paid on the loan was $462. How long was the loan for, in months?

Answer: 6 months

Step-by-ste

462=(10,500)(0.88)t

462=924t

462/924=t

0.5=t

So the loan was 0.5 year's

Since we assume that there are 12 months in a year, the loan was 0.5 .12=6 months
