The maths question for algebra is

1 answer:

4 0

Step-by-step explanation:

Let (2n +1) be the larger odd number by definition, where n can be any real integer. Then (2n - 1) is the smaller consecutive odd number.

The product of the 2 odd numbers is (2n + 1)(2n - 1) = 4n^2 - 1 = 2(2n^2) - 1. Since n^2 must be an integer, 2(2n^2) - 1 is odd. (Shown)

devlian [24]

A+B=15 —>A+15=B(plug this into the other equation)
60a+30b=600
60a+30(a+15)=600
60a+30a+150=600
90a+150=600
90a=450
A=5 (plug back in to first equation)
A+B=15
5+B=15
B=10

They have 5 of the Model A and 10 of model B.

Which linear function represents the line given by the point-slope equation y + 7 = –2/3(x + 6)?a. f(x) = –2/3x – 11b. f(x) = –2

Pavel [41]

Answer:

option C

$y=\frac{-2}{3}x-11$

Step-by-step explanation:

The point slope equation of a line is given by

$y-y_1=m(x-x_1)$

Where m is the slope and (x1,y1) is the point on the point

$y + 7 =\frac{-2}{3}(x + 6)$

We need to write the equation in y=mx+b form

multiply -2/3 inside the parenthesis

$y + 7 =\frac{-2}{3}x-4$

Subtract 7 from both sides

$y=\frac{-2}{3}x-11$
