Y=2x−1 5x−4y=1 Yes or No?

This is a very hard question!! its a math riddle, the teacher said that something like this will be in our test.

katen-ka-za [31]

Answer:

72

Step-by-step explanation:

Let m be the age in years. If s is the son's age in years, then the son is 52x weeks old. If g is the grandson's age in years, then the will be grandson 365m days old. So.... the labels are for the equation.

365m = 52x.

Since the grandson is 12w months old,

12w = months.

Since the grandson, son and the person together are 120 years,

m + x + months = 120.

these are the labels (m, x, and month)

month = 624 x 120 / 1041 = 72.

So, I am basically 72 years old.

hope this helped :D

this is truly very hard.

Give example of a function f: N-> N which is:

stiv31 [10]

An injective function is not a function that is surjective. This means that you want a function that has a unique output for each input, that doesn't cover the natural numbers.
In formal terms a function [Math Processing Error] is injective if [Math Processing Error] implies [Math Processing Error].

We also know that it's not surjective because no value maps to [Math Processing Error] (or any odd number) since if [Math Processing Error], then [Math Processing Error]. However, since [Math Processing Error], the function isn't surjective.

Answer is B.

Eliza and Jamie are making cupcakes for a bake sale at school. Eliza need 2 1/3 c of flour for her recipe, and Jamie needs 1 3/4

marin [14]

2 1/3 + 1 3/4 = 7/3 + 7/4 = (28+21)/12 = 49/12 = 4 1/12. they are 1/12 cups short of having enough

Seth is using the figure shown below to prove the Pythagorean Theorem using triangle similarity:

Damm [24]

Part A: A pair of similar triangles is triangle DEF and triangle GFD.

Part B: Traingle DEF ~ triangle GFD by the AA Similarity Theorem

Part C: By applying the Leg Rule, the length of segment ED = 4 units.

Recall:

Based on the Angle-Angle Similarity Theorem (AA) two triangles that have two pairs of congruent triangles can be proven to be similar to each other.
In a right triangle where the altitude intersects the hypotenuse, the Leg Rule applies, which is: Hypotenuse/Leg = Leg/Part

The Figure of the given triangle DEF is shown in the attachment below.

Part A: A Pair of Similar Triangles

A pair of similar triangles are traingle DEF and triangle GDF

Part B: Reason for Similarity

Triangle DEF and GDF have two pairs of congruent angles, ∠EDF ≅∠DGF and ∠EFD ≅∠GFD.

Therefore, based on the AA Similarity Theorem, Traingle DEF ~ Triangle GDF.

Part C: Length of Segment ED

Given the following,

EF = 8 (Hypotenuse)
EG = 2 (Part)
ED = ? (Leg)

Thus:

8/ED = ED/2 (Leg Rule)

Cross multiply

ED² = (8)(2)

ED² = 16

Find the square root of both sides

ED = 4
