A line with a slope of 3 passes through (2,5). Which choice is an equation of this line?
Answers
Answer:
y=3x-4
Step-by-step explanation:
a slope of 3 means that the equation will definitely start like this
y=3x +/- b
to find b, substitute the coordinates given, so
5=3 x 3 +/- b
5=9 +/- b
5-9=b
-4=b
so the equation would be
y=3x-4

Instructions: Solve the following literal equation.
Solve 3x+ 15y = 24 for x.
Answers
Step-by-step explanation:
3x+15y= 24
x+15y=24/3
x+y= 8/15
x= 8/15-y
The solution for x is x = 8-5y.
Given is an equation 3x + 15y = 24, we need to solve for x,
To solve the literal equation 3x + 15y = 24 for x, we need to isolate x on one side of the equation.
Let's begin by subtracting 15y from both sides of the equation:
3x + 15y - 15y = 24 - 15y
This simplifies to:
3x = 24 - 15y
Now, we can divide both sides of the equation by 3 to solve for x:
(3x)/3 = (24 - 15y)/3
Simplifying further:
x = (24 - 15y)/3
Take 3 as common factor,
x = 3(8-5y) / 3
x = 8-5y
Therefore, the solution for x is x = 8-5y.

Answer:

Step-by-step explanation:
x²+4x+3 = (x+2)²
first of all you open the bracket on the Right hand side..
(x+2)² = (x+2)(x+2)
= x(x+2)+ 2(x+2)
=x²+2x+ 2x+4
= x²+4x+4
therefore,
x²+4x+3 = x²+4x+4
next, we collect all like terms together,
x²-x²+4x-4x = 4-3
0+0 = 1
the answer is undefined

At a soccer tournament 12 teams are wearing red shirts, 6 teams are wearing blue shirts, 444 teams are wearing orange shirts, and 2 teams are wearing white shirts
Answers
Answer:
red
Step-by-step explanation:
The complete question is as follows;
At a soccer tournament 12 teams are wearing red shirts, 6 teams are wearing blue shirts, 4 teams are wearing orange shirts, and 2 teams are wearing white shirts. For every 2 teams at the tournament, there is 1 team wearing ____ shirts
Solution;
The total number of teams we have is 12 + 6 + 4 + 2 = 24 teams
Now looking at the number of teams wearing red shirts , we can see 12 of them which is exactly half the total number of teams
So what this means is that for every two teams at the tournament, there is 1 team wearing red shirts
