Answer:
Given:
Step-by-step explanation:
Identity used:
Y less than 21 = 21 - y
Remember, "less than" indicates a subtraction with the terms in inverted order.
Hope I helped!
Answer:
X = 2
Step-by-step explanation:
Divided 26 (total perimeter) by 4 = maximum side length possible = 26÷4 =.6.5
I used the trial and error technique
Guessed it was 2 working out to see if i was right or wrong:
Length: 2(2) + 3 = 4+3 = 7
Width: 3(2) = 6
7+7+6+6 = 26
Therefore X = 2
Answer: b)
Step-by-step explanation:
You can rule out A) and C), because you have to find area (no adding.)
To do this problem, you can individually multiply the estimated hieght and
width by 3 and then multiply together.
This is because there are 3 walls that each are 9 3/4 tall and 14 1/4 wide. To find total height and width, multiply by 3. Then find total area (lxw)
9 3/4 rounds to 10
14 1/4 rounds to 14
= 3 (10) x 3 (14)
D) is incorrect because you have to multiply each number by 3. (Or you can multiply by 6)
It is B)
let us take any two points here (5,20) and (7,30)
now let us use slope formula to get its slope
slope =5
now let us use one coordinate (say (5,20)) and slope to get the y intercept
20= 5*5 +b
b=-5
plugging the values of b and m in the given equation we get
y=5x-5
or c=5m-5
