Answer:
see below
Step-by-step explanation:
When doing this by hand, it can work well to start at the y-intercept (0, -2) and use the slope value to find additional points on the line. The slope of 5 indicates another point will be 5 units up for each 1 unit right from (0, -2). So, another point will be (1, 3).
Draw the line through the points you found.

Answer:
3x + 2 ≤ 53
Step-by-step explanation:
"2 more than" means that there will be a + 2 in the equation. "3 times a number" means that 3 is multiplied by an unknown number which can be represented by a variable such as x. "At most" means less than or equal to, since the number cannot be greater than.
So generally, you might want to write the equation as 2 + 3x ≤ 53, but 2 + 3x is not in y = mx + b form. Basically, you need to write it as 3x + 2 ≤ 53 because that's how math works.
Answer:
Step-by-step explanation:
Multiply the parenthesis. multiply each term in first parenthesis with each term in second parenthesis.
The value of i^2 is -1
Answer:
There is no unique solution to this problem and there are infinite number of possible solutions which can satisfy these equations.
Step-by-step explanation:
Let S represents Prana's savings account and C represents Prana's chequing account.
Prana has a savings account and a chequing account with a total balance of $85.
Mathematically,
S + C = 85 eq. 1
His parents doubled the amount in each account and the new total balance is $170.
Mathematically,
2(S + C) = 170
2S + 2C = 170 eq. 2
We have two equations and two unknowns.
S + C = 85
S = 85 - C
Substitute the above equation into eq. 2
2S + 2C = 170
2(85 - C) + 2C = 170
170 - 2C + 2C = 170
2C + 2C = 170 - 170
0 = 0
So what does it mean?
it means that there is no unique solution to this problem and there are infinite number of possible solutions which can satisfy these equations.
