Answer:
B)
Step-by-step explanation:
Answer:
y=.5x-2
Step-by-step explanation:
If one line is perpendicular to another that means that their slopes are negative reciprocals
which means that the slope (or m in y=mx+b) is .5
so far we have
y=.5x+b
to solve for b we plug in (8,2)
2=.5(8)+b
2=4+b
-2=b
therefore our equation is
y=.5x-2
<span>Some of the decimals which when multiplied will give a product of about 40 are: (1) 40. and first decimal, (2) 0.40 and the second decimal, and lastly (3) 4.0 and the third decimal. It must be noted that the multiplication of a number with a decimal will move the decimal place one place to the right. </span>
Answer is 3
Step-by-step explanation:
first what you do is you rearrange the numbers so the eqaution is -2x+4=-2
SO what you do is (4) - 4 to cancel it out then you do the same thing on the other side so (-2)-4=-6 so the equation now is -2x=-6 then you divide -2 to cancel it out and you do the same thing -6 divide by -2 is 3 so the answer is 3
Answer:
36.9°
Step-by-step explanation:
The relevant trig relation is ...
Cos = Adjacent/Hypotenuse
cos(x) = 8/10 = 0.8
The inverse trig function is used to find the angle:
x = arccos(0.8) ≈ 36.9°
