Median: 5 3/4 ( in a number line from least to greatest, the middle number)
Mode: 6 5/8 ( the number that appears the most [ex: 1,1,2,2,2,3,3 your mode will be 3])

hope this helps

Iona wrote out the description of each step for her multiplication of the binomial and trinomial (2x – 3)(5x2 – 2x + 7)

Olin [163]

Steps for multiplying the given binomial and trinomial $(2x-3)\times (5x^{2}-2x+7)$ are:

Step 1: $2x\times (5x^{2}-2x+7)-3 \times (5x^{2}-2x+7)$

Step 2: $10x^{3}-4x^{2}+14x-15x^{2}+6x-21$

Step 3: $10x^{3}-19x^{2}+20x-21$

Which set of steps will translate f(x)=6x to g(x)=6x-5-7

Maurinko [17]

THIS IS THE COMPLETE QUESTION BELOW;

Which set of steps will translate f(x) = 6x to g(x) = 6x – 5 – 7?

Shift f(x) = 6x five units to the left and seven units up.

Shift f(x) = 6x five units to the right and seven units down.

Shift f(x) = 6x seven units to the right and five units up.

Shift f(x) = 6x seven units to the left and five units down.

Answer:

Shift f(x)=6x five units to the left and seven units down.

Step-by-step explanation:

We are told to translate the function below

f(x) = 6x to g(x) = 6x – 5 – 7

Which means the process to translate f(x) into g(x) is required.

According to the translation rule

f(x)-------->f(x)+a

If a<0 it shift to downward

If a>0 it shift to upward

Then we have

(X,y) ----->((x - 5, y)

There is a shift by x coordinates towards left by 5 units

then we would have the function as

f'(x) = 6(x-5)

Following the translation rule there is a shift by the function by 7 units downward direction then we have

(x,y) ----->(x,y -7)

Then we have g(x) = 6x – 5 – 7 as our translation product.

Therefore, shift f(x)=6x five units to the left and seven units down.

9. Simran had some ₹2 and ₹ 5 coins.She exchanged them for ₹ 10 coins. If the number of ₹ 5 coins is one less than the number of

sertanlavr [38]

Answer:

Step-by-step explanation:

Let x be the number of 2 coins and y be the number of 5 coins. Let z be the number of 10 coins she exchanged. Then, we have the first equation

$2x+5y = 10z$

Since she has one 5 coin less than 2 coins, then y=x-1. So we get the equation

$2x+5(x-1) = 10z$

which is equivalent to

$7x-5 = 10z$

If we add 5 on both sides and factor out on the right by 5 we get

$7x = 5(2z+1)$

We can solve for x and get

$x = \frac{5(2z+1)}{7}$

Since x represents the number of 2 coins, we must have that x is an integer. That is, we cannot have, for example 1.5 2 coins. Since 7 doesn't divide 5, we must have that 7 divides 2z+1. That is, the value of z is such that the number 2z+1 is multiple of 7. That is 2z+1 = 7p where p is an integer.

If that is the case, then

x = 5p, then y = 5p-1. By having 2z+1 = 7p, we are forcing that p is an odd integer, so we have infinite solutions. For each value of p that is an odd integer, then x=5p and y=5p-1 is a solution to the problem
