Answer:
If solving a linear equation leads to a single solution such as x = 3, the equation is conditional. Its solution set consists of a single element.
Answer:
Step-by-step explanation:
Slope = (change in y)/ (change in x)
= (13 - 3)/(1 - (-1))
= (13 - 3)/(1 + 1)
= 10/2
= 5
Y = mx + b
slope(m) = 2/3
(-3,5)...x = -3 and y = 5
now sub and find b, the y int
5 = 2/3(-3) + b
5 = -2 + b
5 + 2 = b
7 = b
so ur equation is : y = 2/3x + 7
It looks difficult but it’s pretty easy. Just use the Ln function to bring down the powers then simplify.
A) 9(x + 4) = 27
9x + 36 = 27
9x = 27 - 36
9x = -9
x = -9 ÷ 9
x = -1
B) x/3 - 5 = 6
x/3 = 6 + 5
x/3 = 11
x = 11 × 3
x = 33
C) 15 + 3 ( x -7 ) = -30
15 + 3x - 21 = -30
3x + 15 - 21 = -30
3x - 6 = -30
3x = -30 + 6
3x = -24
x = -24 ÷ 3
x = -8
