Nobody is going to answer all that for 10 points lol
Answer:
x = 2, y = - 1
Step-by-step explanation:
Given the 2 equations
y = - 7x + 13 → (1)
y = - 1 → (2)
Substitute y = - 7x + 13 into (2)
- 7x + 13 = - 1 ( subtract 13 from both sides )
- 7x = - 14 ( divide both sides by - 7 )
x = 2
y = - 1 is already given in (2)
Then x = 2, y = - 1
Answer:
x=3.5
Step-by-step explanation:
12x=4(x+2)+20
multiply the parentheses by 4
12x = 4x+8 +20
add 20 to 8
12x = 4x +28
subtract 4x on both sides
8x = 28
divide both sides by 8
x=3.5
Answer:
(b) 0.3 microns or larger
Step-by-step explanation:
A particle of size 0.3 microns is judged to be the most penetrating particle size. So, a rating for the filtering of those particles will be a worst-case rating. For particles of any other size, the filter will perform better than for 0.3 micron particles. HEPA filters are rated based on their performance with particles ...
0.3 microns or larger
Given:
the design is to be rotated about the line x = 1 to produce the shape of the urn.
To generate a design for the urn, we need to draw a vertical line at x = 1, this will be our axis of rotation (or the basis for our mirror). We will use the mirror principle in making our design. So we will either draw half the shape of the urn at the left or right side of the axis of rotation.
