<span>If xy plane line is y=2x+4, y=x-5 will intercept at which point? (-9,-14)</span>
Find two points on the graph that the line crosses through almost perfectly. It looks like (1,10) and (9,1) will do.
Use them to compute the slope:
m = (1 - 10) / (9 - 1)
= -9/8
Then set up the "point-slope form":
y - y0 = m * (x - x0)
You choose some point (x0, y0) that the line crosses through. We already know the line passes through (1,10) pretty well, so let's use that.
x0 = 1
y0 = 10
Now finish plugging into the equation:
y - 10 = -9/8 * (x - 1)
The above equation will work fine for an answer, but let's go a step further and solve for y.
y - 10 = -9/8x + 9/8
y = -9/8x + 9/8 + 10
y = -9/8x + 9/8 + 80/8
y = -9/8x + (9 + 80)/8
y = -9/8x + 89/8
Answer:
Cross-sectional study.
Step-by-step explanation:
- In a cross-sectional study, data are observed, measured, and collected at one point in time.
- In a prospective (or longitudinal) study, data are collected in the future from
groups sharing common factors.
- In a retrospective (or case-control) study, data are collected from the past by going
back in tirme (through exanmination of records, interviews, arıd so on).
Hope this Helps!!
Answer:
The answers would be as follows:
1. d
2. a
3. a
Step-by-step explanation:
To find the combined terms, focus only on the terms that have the same variable value. See the examples below.
1.
7 + 19t - 6t
7 + (19t - 6t)
7 + 13t
2.
5/6x - 2/3x
(5/6x - 2/3x)
1/6x
3.
8 + 16r - 9r
8 + (16r - 9r)
8 + 7r
