What number can go into 2470,121 and 45<br>​
Usimov [2.4K]

Answer:

Step-by-step explanation:

All of these numbers can be divided by 2, 3, 5, 7, 11, 13...

There is no whole number if you want to divide each number.

121 only goes into 1, 11, and 121. No other numbers have 11

45/2 = 22.5

45/3 = 15

45/5 = 9

2470/2 = 1235

2470/3 = 823.33333...

2470/5 = 494

121/2 = 60.5

121/3 = 40.33333...

121/5 = 24.2

Scilla [17]
<span>Ariel deposited 100$ into a bank account. Each Friday she will withdraw 10% of the money in the account to spend. Ariel thinks her account will be empty after 10 withdrawals. Do you agree? Explain
OK, my initial answer is YES. I agree.
Why? Let me show you the solutions
=> 100 dollars = the money of Ariel in the bank
=> 10% = he withdraw every Friday
10% of 100 is:
=> 100 / 10 = 10 dollars
Thus,  after his 10th withdrawal, his account will be empty.</span>

Help me please ❤️❤️❤️❤️
melomori [17]

In a quadratic function, f(x)= ax^2+bx+c the leading coefficient is a, i.e. the coefficient of x^2, and the constant term is c, i.e. the coefficient without any power of x.

So, if you want leading coefficient 2 and constant term -3, your function needs to be like

f(x)=2x^2+bx-3

for any value of b. Among your options:

  • The first is not a quadratic (it starts with x^3)
  • The second has leading term -3 and constant term 2
  • The third is not a quadratic (same as the first)
  • The last is correct.

If the point (2-3) lies on the graph of the equation 2y=ax-7 then find the value of a​
Tom [10]

Answer:

a = 1/2

Step-by-step explanation:

The given equation is :

2y=ax-7 ...(1)

The point (2,-3) lies on the graph of this equation.

We need to find the value of a.

Put x = 2 and y = -3 in equation (1)

2(-3) = a(2) -7

-6 = 2a-7

-6+7 = 2a

2a = 1

a = 1/2

Hence, the value of a is 1/2.
