7

A number is 5 more than 3 times another number. The sum of the two numbers is 33. As an equation, this is written x + 3x + 5 = 3

3, where x represents the smaller number. Plug in the numbers from the set {3, 5, 7, 9} to find the value of x.
The value of x that holds true for the equation is?
So, the smaller number is?
and the larger number is?

Step-by-step explanation:

the numbers : x, y

x = 5 + 3y

x + y = 33

when using the first equation in the second we get the mentioned equation (it does not matter which of the 2 numbers is x and which is y, it can all be vice versa, as you can see) :

5 + 3y + y = 33

5 + 4y = 33

4y = 28

y = 7

so, when you try the numbers above in the unsimplified equation, you will also find that 7 is the right answer.

the other number is based on my equations (with the reversed names) :

x = 5 + 3y = 5 + 3×7 = 5 + 21 = 26

the smaller number is 7.

the larger number is 26.

Could ΔABC be congruent to ΔADC by SSS? Explain.
Vera_Pavlovna [14]
There are 5 ways to test if two figures are congruent, namely;
side-angle-side(SAS)
Angle-side-angle (ASA)
Angle-angle-side(AAS)
Hypotenuse-leg (HL)
3 Sides (SSS)
here we shall focus on SSS. When the three corresponding sides of 2 figures say a triangle have the same length we will conclude that the triangles are congruent by SSS.
Therefore from our choices we can conclude that   triangles ABC and ADC are only congruent if the two other side have the same length and BC=DC.

The answer is yes;
B] Yes, but only if BC=DC

Just answer no need to explain.

Shifting to left mean adding the number from each occurrence of x from the given function.

So, shifting x³ , 3 units to left will result in:

f(x) = (x + 3)³

Shifting down means subtracting the number from the function value. 

So, shifting 2 units down will result in:

f(x) = (x + 3)³ - 2

Therefore, option A is the correct graph
