Answer:
8
Step-by-step explanation:
3 + 5 = 8
To answer the problem above, use the concept of ratio and proportion. The ratio between 1 cm to 21 km should be the same as the ratio of 3.1 cm to the actual distance. Let x be the unknown actual distance and mathematically express the situation,
(1 cm/ 21 km) = (3.1 cm / x km)
This equation gives a value for x which is 65.1 km. Therefore, the answer is letter C.
Slope = (2+2)/(6-3) = 4/3
a)
point slope intercept
y + 2 = 4/3(x - 3)
standard form
y + 2 = 4/3(x - 3)
3y + 6 = 4x - 12
- 4x + 3y = -18 ..........this is standard form
Answer is C
y + 2 = 4/3(x - 3); -4x + 3y = -18
Answer:
havent got tought this yet sorry wish i can help
Answer:
y - 7 = -1/4(x-4)
Step-by-step explanation:
point slope is y-y₁=m(x-x₁)
(4, 7) and (8, 6)
I like to put it in the slope-intercept form first
so... 6 - 7/ 8-4 = -1/4 (slope)
6 = -1/4(8) + b
6/(-2) = -2/(-2) + b
-3 = b
so... y=-1/4x + -3
plug it in to point slope form
y - 7 = -1/4(x-4)
hopefully that made sense :)
