PLEASE SEND HELP!!! I need to finish this test in 20 minutes.

Someone please help me make a proof for the bottom question

Lerok [7]

Answer:

DB = CA (Proved)

Step-by-step explanation:

Statement 1.

∠D = ∠C, M is the midpoint of DC and ∠1 = ∠2

Reason 1.

Given

Statement 2.

Between Δ DBM and Δ CAM,

(i) DM = CM,

(ii) ∠D = ∠C and

(iii) ∠DMB = ∠CMA

Reason 2.

(i) given

(ii) given and

(iii) ∠ DMB = ∠1 + ∠AMB and ∠CMA = ∠2 + ∠AMB

Since ∠1 = ∠2, so, ∠DMB = ∠CMA.

Statement 3.

Δ DBM ≅ Δ CAM

Reason 3.

By angle-side-angle rule.

Statement 4.

DB = CA

Reason 4.

Corresponding sides of two congruent triangles. (Answer)

Problem page the sum of two numbers is 47 . the larger number is 17 more than the smaller number. what are the numbers?

user100 [1]

Smaller number = X
Larger Number = X + 17

47 = X + (X+17)
47 = 2x + 17
47 - 17 = 2x
30 = 2x
X = 15

Please answer 10 point + brainlyest = 1 big thank u

solmaris [256]

<em><u>Step-by-step explanation:</u></em>

FIRST, we want to understand every property:

Associative Property: The associative property states that you can add or multiply regardless of how the numbers are grouped so (5 + 4) + 3 = 5 + (4 + 3)

Commutative Property: Commutative is the one that refers to moving stuff around so 3 + 2 = 2 + 3

Additive Inverse Property: This is the number that when added to the original number, equals 0 or it's the opposite of the number so 5 <- is the original number and -5 <- is the additive inverse.

Simplify: Is just to add like terms, and make the equation the simplest.

How can you tell if a point is a solution to a system of equations?

Anna35 [415]

Answer: you have to substitute them into the equation

Step-by-step explanation:

example: x = 2y - 6

lets say you test 4/5 so it would be 4 = 2(5) - 6

this equals 4 = 10 - 6 which is true

so that is how you test to see if the equation is right

remember the first number goes to "x" and the second one goes to y

hope this helps mark me brainliest if you can

Company A: $39.99 per month no installation fee

Svetlanka [38]

Company A represents a proportional relationship, while company B does not.

<h3>Proportional relationship</h3>

The general format of a equation representing a proportional relationship is given as follows:

y = rx.

A proportional relationship is a special case of a linear function, having an intercept of zero.

Then, the output variable y is calculated as the multiplication of the input variable x by the constant of proportionality k.

The costs for each company after x months, in this problem, are represented as follows:

A(x) = 39.99x.

B(x) = 34.99x + 50.

Company B has an intercept different of zero, hence it is not a proportional relationship, while Company A, with an intercept of zero, represents a proportional relationship.

<h3>Missing Information</h3>

The complete problem is:

Two companies offer digital cable television as described below.

Company A: $39.99 per month no installation fee

Company B: $34.99 per month with a $50 installation fee

For each company tell whether the relationship is proportional between months of service and total cost is a proportional relationship. Explain why or why not
