Hey there! :)
Answer:
-1/2.
Step-by-step explanation:
For a line to be perpendicular, the slope must be the negative reciprocal of the original. In this instance:
A line perpendicular to y = 2x + 7 must contain a slope that is the negative reciprocal of 2.
The negative reciprocal of 2 is -1/2. This is the slope of a perpendicular line.
Mary = M Chris = C
M = 3C-4
M-3=C+9 --> M=C+12
3C-4=C+12
2C=16
C=8
M=3C-4 --> C=8
M=3(8)-4
M=24-4
M=20
Mary is 20, and Chris is 8
Answer:
<h3>13 reams</h3>
Step-by-step explanation
Given
Total number of pages to complete the packet = 6400 pages
If each ream contains 500pages, then:
Total number of reams needed = Total pages/number of pages per ream
Total number of reams needed = 6400/500
Total number of reams needed = 12.8
<em>Hence you will need about 13 reams for all the packets</em>
Given, Earth's diameter is approximately 12,760,000 meters.
This number in scientific notation will be 1.276 × 10⁷
Answer:
f(4) = 5
Step-by-step explanation:
functions are represented by f(x), so x should be the value in parenthesis and the y value should be what it equals
