Step-by-step explanation:
<u>Y2 - Y1</u>
X2 - X1
<u>3 - 1</u>
2 - 1
= 2
y - Y1 = m (x - X1)
y - 1 = 2(x - 1) --- IN POINT SLOPE FORM
y - 1 = 2x - 2
+ 1 + 1
y = 2x - 1 --- IN SLOPE INTERCEPT FORM
QUESTION 12:
Slope intercept form -
- y = mx + b
- m represents the slope
- b represents the y - intercept AKA the starting point
- When the slope is negative, you go down
- When the slope is positive, you go up
ABOUT PROBLEM:
- Since the slope is negative, you go down 4, right 3, but start from the 2 then start doing the slope
- You have to put 2 on the y - line because it's the y - intercept AKA starting point
y = -4/3x + 2
Answer:
Length of the other side of the backyard is 80.4 feet.
Step-by-step explanation:
Let the dimensions of the Liam's rectangular backyard = 85 feet × a feet
Diagonal of the rectangle, AD = 117 feet
When we apply Pythagoras theorem in ΔABD,
AD² = AB² + BD²
(117)² = (85)² + BD²
a² = 13689 - 7225
a = √6464
= 80.399 feet
a ≈ 80.4 feet
Therefore, length of the other side of the backyard is 80.4 feet.
Answer: 44 years
Step-by-step explanation:
Let Brita's age be x and the daughter's age be y , then from the first statement :

From the second statement :

solving the resulting linear equation , add the two equations , we have


substitute 74 into equation 1 to find the value of y



Therefore :
Eva = 44 years
4/52= 0.07692 so it would be C. 0.077
100 is 101 to the nearest ten
