Hey!

------------------------------------------------

Steps To Solve:

f(x) = 8x + 15 if f(-7)

~Substitute

f(-7) = 8(-7) + 15

~Multiply

f(-7) = -56 + 15

~Add

f(-17) = -41

------------------------------------------------

When f(-7) it's -41!

A pencil costs $0.45, an eraser costs $0.30, and a pencil sharpener costs $0.30. What is the cost of 3 pencils, 2 erasers, and 1

alexandr1967 [171]

Hi!

We know the prices of one pencil, one eraser and one pencil sharpener, which are $0.45, $0.30 and $0.30, respectively. Given that, we will find the cost of 3 pencils, 2 erasers and 1 pencil sharpener like this:

3 * 0.45 + 2 * 0.30 + 1 * 0.30 = 1.35 + 0.60 + 0.30 = 2.25

The cost of 3 pencils, 2 erasers and 1 pencil sharpener is $2.25.

Hope this helps!

How many solutions does the equation x_1 +x_2+x_3+x_4+x_5=21 have where x_1, x_2, x_3, x_4, and x_5 are nonnegative integers and

omeli [17]

Step-by-step explanation:

$x_{1} + x_{2} + x_{3} + x_{4} + x_{5} = 21\\$ (given)

Let us consider :

$x_{1}$ = $t_{1} + 1$

$x_{2}$ = $t_{2}$

$x_{3}$ = $t_{3}$

$x_{4}$ = $t_{4}$

$x_{5}$ = $t_{5}$

Now, by substituting the above considerations in the above equation, we get:

$t_{1} + 1 + t_{2} + t_{3} + t_{4} + t_{5} = 21\\$

$t_{1} + t_{2} + t_{3} + t_{4} + t_{5} = 20\\$

where,

$t_{i}$ $\geq$ 1

then it follows

n = 20

r = 4

then no. of solutions for the eqn = $_{r}^{n + r}\textrm{C}$

= $_{4}^{24}\textrm{C}$

= 10626

Answer :

no. of solutions for the eqn 10626

Is a megabyte bigger than a gigabyte.

san4es73 [151]

Answer:

NO!!! Megabytes AREN'T bigger than Gigabytes!

Step-by-step explanation:

Here's the table!

1 Kilobyte = 1,024 Bytes

1 Megabyte = 1,024 Kilobytes

1 Gigabyte = 1,024 Megabytes

1 Terabyte = 1,024 Gigabytes

<h2>From this we can see that Megabyte <em>ISN'T</em> bigger than Gigabyte</h2>
