Which graphs represent functions?
Answers
Answer:
A. Only graph B and D
Step-by-step explanation:
Hi, to answer this question we have to analyze the options given:
A function has only one output value (y) for each input value.(x)
In other words, If we draw a vertical line (anywhere on the graph) that intersects the graph in two points or more, then the graph does not represent a function because that x value has more than one output(y).
So, the correct option is:
A. Only graph B and D

Equation B: c = 3d + 5
Which of the following is a step that can be used to find the solution to the set of equations?
2d + 1 = 3d + 5
2d = 3d + 5
2d + 1 = 3d
2d + 5 = 3d + 1
Answers
Answer:
The correct option is 1.
Step-by-step explanation:
The given set of equations is
Equation A: c = 2d + 1
Equation B: c = 3d + 5
Using equation A and equation B, equate the value of c.
The value of d is -4. So the value of c is
The equation 2d+1=3d+5 is used to find the solution to the set of equations, therefore the correct option is 1.
If both equations equal c, then both equations can be equal to each other.

Do the inverse operation.
6x - 1/5 = 3
+1/5 +1/5
6x = 3 1/5
6x/6 = 3 1/5 /6
KCF:- Keep the first fraction, change the sign, flip the second fraction.
3 1/5 divided by 6/1
3*5 +1 = 15+1 =16
16/5 * 1/6
16*1 = 16
5*6 = 30
16/30 = 16/2 and 30/2
8/15
Final answer: x = 8/15

What information is marked in the diagram ?
-- The angles in the lower left corner of each triangle are
right angles, so the triangles are right triangles.
-- The angles in the lower right corner of each triangle are equal.
-- The slanted sides of both triangles are equal. (Since the triangles
are right triangles, the slanted sides are their hypotenees.)
If the hypotenuse and one acute angle of a right triangle are
equal respectively to the hypotenuse and one acute angle of
another right triangle, that's enough to prove that the triangles
are congruent.

As there are infinite numbers, the list of multiples are also infinite.
Multiples of 6 : 6, 12 , 18 , 24 ..............
Answer:
True; yes.
Step-by-step explanation:
Think about it, what does etc, etc mean? It means repetitive-a pattern, in a sort of way. So here are some multiples of 6:
6,12,18,24,30,36,42,48,54,60,66,72,78,84,90,96,102,108,114,120,126,132,138,144,150,156,162,168,174,180,186,192,198,204,210,216,222,228,234,240,246,252,258,264,270,276,282,288,294, etc.
As you can see, all I'm doing is adding 6 to every step I go. So when you say there is an infinite number, then these multiples are going to be infinite.

Δ DMU & Δ MPA both are right triangles.
DMU: short leg = 12 ; hypotenuse = 15
MPA: short leg = 0.5x + 6 ; hypotenuse = 2y - 3
x = 12 ; y = 9
12 = 0.5(12) + 6
12 = 6 + 6
12 = 12
15 = 2y - 3
15 = 2(9) - 3
15 = 18 - 3
15 = 15
SAS postulate states that if 2 sides and 1 angle of 1 triangle is congruent to the 2 sides and 1 angle of another triangle. Then, these triangles are congruent.
Since sides are already computed, you need to look for the congruent angles of each triangle. In this case, since both are right triangles, its congruent angle is 90°
