Answer:
Step-by-step explanation:
y = -1/2 x – 7
when x is 0
y = -1/2(0) - 7
y = - 7
(0,-7)
when y is 0
0 = -1/2 x - 7
1/2 x = -7
x = -7(2)
x = -14
(-14,0)
Answer: 2m > 6ft, 10kg > 10lb
Step-by-step explanation:
6 ft is 72 inches (12 inches per foot)
2 m is a little over 78 inches (39+ inches per meter)
10kg is 22lb (2.2 lb per kg)
Answer: someone who is viewed as obsolete or a person you can use to save yourself from any problem/situation
Step-by-step explanation:
Answer:
x ≈ 5.4
Step-by-step explanation:
Using the sine ratio in the right triangle
sin64° = 
= 
( multiply both sides by 6 )
6 × sin64° = x , then
x ≈ 5.4 ( to the nearest tenth )
To answer this question, you need to write a linear equation (because the graph is a visibly straight line) that models this situation, then plug in 12.
The general format for a linear equation is y=mx+b, where m is the slope and b is the y intercept. The y intercept of a line is where it crosses the y axis; for this line, it crosses the y axis at (0, 0) so the y intercept is 0.
To find the slope, use the slope equation: (y2-y1)/(x2-x1). For y1, y2, x1, and x2, just pick any two points on the line. We will use (1, 30) and (2, 60):
(60-30)/(2-1)
30/1
30
The line is y=30x.
Plug in 12 for x:
y=30(12)
y=360
3). 360
Hope this helps!!
