Answer:
hi! you have 2 points! this means slope formula! y2-y1/x2-x1
okay all you do now is plugin! (x1 1,y1 3) (x2 3,y2 7) what I did was label your x1 y1 x2 y2! now just follow the formula and that / is division or basically a fraction
7-3/3-1
that equals -5! and that's your slope! memorize the formula it helpss!
Answer:
29t + 24
Step-by-step explanation:
5(5t + 6) + 2(2t - 3)
Open Parentheses first.
5* 5t = 25t
5 * 6 = 30
25t + 30 + 2(2t - 3)
Open others
2 * 2t = 4t
2 * 3 = 6
25t + 30 + 4t - 6
Match like terms
29t + 24
3x + 1 = y
2x + 3y = 14
To solve this system of equations, we are going to use the substitution method. Substitution the equation where the variable is isolated into the second equation. In this system of equations, y is isolated, so we will replace y in the second equation with 3x + 1.
2x + 3y = 14
2x + 3(3x + 1) = 14
2x + 9x + 3 = 14
We will add the like terms and subtract 3 from both sides of the equation.
11x + 3 = 14
11x = 11
x = 1
In this system of equations, x is equal to 1. Now we will go back and solve for y, plugging in 1 for x.
3(1) + 1 = y
2(1) + 3y = 14
3 + 1 = y
2 + 3y = 14
4 = y
3y = 2
4 = y
4 = y
The solution to this system of equations is (1, 4).
