The sum of a number and two times a smaller number is 98. The bigger number is 22 less than three times the smaller number.
IgorC [24]
B>a 

<span>b=3a-22, b+2a=98, using b from the left in the right: </span>

<span>3a-22+2a=98 </span>

<span>5a-22=98 </span>

<span>5a=120 </span>

<span>a=24, and since b=3a-22, </span>

<span>b=50 </span>

<span>So the smaller number is 24 and the larger number is 50.</span>

Y= (x-1)^2 + 2 <br><br> change this equation into standard form
BaLLatris [955]

Answer:

x² - 2x + 3

Step-by-step explanation:

y = (x - 1)² + 2

= (x - 1)² + 2 [a - b]² = <em><u>a²- 2ab + b²</u></em>

= x²- 2x + 1 + 2

= x² - 2x + 3

Thus, the standard form of the equation is x² - 2x + 3

How are the slopes when the lines are parallel in a square ?
Aleks [24]

The slope of parallel lines is equal and the slope of perpendicular lines is a negative multiplicative inverse of each other.

<h3>What is the standard equation of a line?</h3>

The standard equation of a line is given by

y = mx+c

Here m is the slope and c is the y-intercept

The slope can be determined by

m = (y₂ -y₁)/(x₂ -x₁)

A square is a polygon with four sides, the opposite sides are parallel and all the sides are equal, all the angles have an equal measure of 90 degrees.

Two lines are parallel to each other when they are at a fixed distance always and never intersect with each other.

The slope of the lines parallel to each other is equal.

Two lines are said to be perpendicular when they intersect at 90 degrees.

The slope of two perpendicular lines has a product of -1.
