F(10) calculate the indicated function value

The sum of two numbers is 72 and their difference is 40. Using elimination method

d1i1m1o1n [39]

Answer:

here's what we know:

a + b = 72

a - b = 26

We can use the elimination method to solve this problem:

a + b = 72

a - b = 26

---------------

2a = 98

Divide both sides by 2:

a = 49

So we now have:

49 + b = 72

and:

49 - b = 26

Subtract 49 from both sides:

b = 23

and

-b = -23 (multiply both sides by -1) → b = 23

Please answer!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer:

The length of the hypotenuse is 26 inches

Step-by-step explanation:

The leg(brace) attached to the wall is 10 inches

Perpendicular = 10 inches

Your surfboard sits on a leg that is 24 inches.

Base = 24 inches

Formula : $Hypotenuse^2 = Perpendicular^2 +Base^2$

$Hypotenuse^2 = 10^2+24^2$

$Hypotenuse = \sqrt{10^2+24^2}$

Hypotenuse = 26

Hence the length of the hypotenuse is 26 inches

If Included in the table, which ordered pair (-4,1) or (1,-4), would result in a relation that is no longer a function. Explain

Kruka [31]

Answer:

(-4,1)

Step-by-step explanation:

Ordered pair (-4,1) means that x = -4 and f(x) = 1

Ordered pair (1,-4) means that x = 1 and f(x) = -4

From the table, we can see that the function is already defined for x = -4, but it is not defined for x = 1. So, the point (1,-4) can be included into the function, but the point (-4,1) cannot.

Answer:

The Length of JK is 10

Step-by-step explanation:

Because <J is congruent to <L we know that the triangle in question must be isosceles as in an isosceles triangle two angles opposite of each other are equal. (This is also true for equilateral triangles, however, in an equilateral triangle all sides must be congruent, so we can rule equilateral out as LJ is not congruent to KL.) This means that the triangle must be isosceles.

In an isosceles triangle the side opposite each other are congruent, and the angles opposite each other are congruent when split down the line of symmetry.

Therefor, the length of JK must be congruent to the length of KL. In other words if JK = 10, then KL must equal 10 as well.

Describe the possible configurations and the possible number of points of intersection of (a) 2 lines in the plane (b) 3 lines i

FinnZ [79.3K]

Answer: The answer is given below.

Step-by-step explanation: The description is as follows:

(a) 2 lines in the plane : Any two lines in a plane can either be parallel or intersect at only one point.

(b) 3 lines in the plane : Any three lines in a plane may intersect at a point, if so, they are called concurrent lines, or they may never intersect.

(c) 2 lines in space : There are exactly three possibilities.

* The two lines are distinct and they have no points in common.

* The two lines are distinct and they have exactly one point in common.

* The two lines are really the same line and they have all of their points in common.

(d) ) 3 planes in space : Here also, we have three possibilities:

* The three planes are distinct and they have no points in common.

* The three planes share exactly one point.

* The three planes share infinitely many points, i.e., they could all share a line or they could all be the same plane.
