$\boxed{2\:x}$ , x + 2 , 2 - x

5 - x , x , $\boxed{2x\:-\:1}$

$\boxed{x\:-\:1}$ , 2 , $\boxed{x\:+\:3}$

Each row and column sums to $\sf\purple{2x\:+\:4}$ .

$\large\mathfrak{{\pmb{\underline{\orange{Happy\:learning }}{\orange{.}}}}}$

Julio joined an athletic club. There was a one-time fee of $49.95 to join the club, plus a monthly fee of $24.95. Julio has paid

Rama09 [41]

c (cost)
m (month)

c= xm + b

$424.20= 24.95m+ $49.95

Move everything except variable on one side.

424.20 - 49.95 = $374.24

$374.25 = 24.95m

Divide by 24.95

m = 15

Which quadratic function has a leading coefficient of 2 and a constant term of –3?

Romashka [77]

The answer is <span>f(x) = 2x2 + 3x – 3
</span>
f(x) = ax² + bx + c
a - the leading coefficient
c - the constant term

<u>We are looking for a = 2, c = -3</u>

Through the process of elimination:
The first (f(x) = 2x3 – 3) and the third choice (f(x) = –3x3 + 2) have x³ so these are not quadratic function.

In the function: <span>f(x) = –3x2 – 3x + 2
</span>a = -3
c = 2

In the function: f(x) = 2x2 + 3x – 3
a = 2
c = -3

Solomon has read 1/3 of his book. He finishes the book by reading the same amount each night for 5 nights.

Nadusha1986 [10]

Answer:

A - Solomon read $\frac{2}{15}$ of the book each night.

B - The total number of pages in the book are 105.

Step-by-step explanation:

We are given that,

Solomon has read $\frac{1}{3}$ of a book.

So, $1-\frac{1}{3}=\frac{2}{3}$ of the book is left to be read.

Ques A: We have that,

In 5 nights, Solomon read $\frac{2}{3}$ of the book.

So, on 1 night, he will read, $\frac{2}{3}\times \frac{1}{5}$ = $\frac{2}{15}$ of the book.

Thus, Solomon read $\frac{2}{15}$ of the book each night.

Ques B: Let the total pages of the book = x.

Solomon reads 14 pages in 1 night. So, he reads, 14 × 5 = 70 pages in 5 nights.

Since, these 70 pages represent the $\frac{2}{3}$ of the book, he read in 5 nights.

So, $\frac{2}{3}$ of the total pages = 70

i.e. $\frac{2}{3}x=70$

i.e. x= 105

Hence, the total number of pages in the book are 105.
