Standard form of any decimal is the given decimal, 0.0054 = to 0.00000054 x 10^3 to my knownledge
you are correct. all angles (except central) are not equal (iff TU and CB are not parallel)
the triangles are not similar
Answer:
<u>Perpendicular</u><u> </u><u>line</u><u> </u><u>is</u><u> </u><u>7</u><u>y</u><u> </u><u>=</u><u> </u><u>x</u><u> </u><u>-</u><u> </u><u>2</u><u>6</u>
<u>Parallel</u><u> </u><u>line</u><u> </u><u>is</u><u> </u><u>y</u><u> </u><u>=</u><u> </u><u>-</u><u>7</u><u>x</u><u> </u><u>-</u><u> </u><u>3</u><u>2</u>
Step-by-step explanation:

from line: y = -7x + 3
m1 is -7
gradient for needed line:
for y-intercept, at point (-2, -4):
equation:
<u>»</u><u> </u><u>F</u><u>o</u><u>r</u><u> </u><u>p</u><u>a</u><u>r</u><u>a</u><u>l</u><u>l</u><u>e</u><u>l</u><u> </u><u>l</u><u>i</u><u>n</u><u>e</u><u>:</u>
gradients are the same, m = -7
for y-intercept, at (-2, -4):
62 rows of 9 chairs.
The questions asks about how many, so we are estimating. So we will round 62 down to 60 and 9 up to 10.
So, 60 rows of 10 chairs.
Then we multiply 60 * 10 to get 600.
The exact amount of 62*9 = 558, but we are estimated so our estimation would be there are about 600 chairs.
7. 7-2 = 5
5 x 2 = 10.
answer: x = 7
