Answer:
y -15 = -3(x +2)
Step-by-step explanation:
The slope will be ...
m = (y2 -y1)/(x2 -x1)
m = (-18 -15)/(9 -(-2)) = -33/11 = -3
Point-slope form is ...
y -y1 = m(x -x1) . . . . . line with slope m through point (x1, y1)
Using the first point, the equation is ...
y -15 = -3(x +2)
The answer would be B) 1 3/4.
Answer:
There is no solution (since none has side length of 4 units)
Step-by-step explanation:
If V (-1,1) is one of vertex of a square, then the next vertex to V distance must be the known value of 4
VA: V to (-3,3) = √(-1 - -3)² + (1 - 3)² = √8 = 2.8
VB: to (-5,-3) = √(-1 - -5)² + (1 - -3)² = √32 = 5.7
VC: o (3,3) = √(-1 -3)² + (1 - 3)² = √20 = 4.47
VD: to (-5,3) = √(-1 - -5)² + (1 - 3)² = √20 = 4.47
VE: to (4,5) = √(-1 - 4)² + (1 - 5)² = √41 = 6.4
Answer:
Answer (C) ⇒ He replaced the wrong term with its reciprocal in step 2
Answer (A) ⇒ How many 3/8 's in 48
Step-by-step explanation:
∵ The distance = 25 miles
∵ The time = 2/3 hour
∵ Average speed = distance ÷ time
∴ Average speed = 25 ÷ 2/3 ⇒ step 1 (he is √)
= 25 × 3/2 ⇒ step 2 (his 1st error 1/25 × 2/3)
= 75/2 miles/h
∵ How many 3/8 's are in 48 means:
48 ÷ 3/8 = 48 × 8/3 = 128
∴ Answer (A) is best modeled with a division expression
Answer:
1. 3
2. -2
3. (1, 2)
Step-by-step explanation:
y axis is the numbered line that looks like the |
x axis is _
so the y int is 3 because A intercepts the y axis at 3
the y int for B is -2 because it intercepts the y axis at -2
the intersection of both lines is (1, 2) because you look and the point is at 1 for x and 2 for y
