Answer:
y=-10x+3
Step-by-step explanation:
The slope is -10
In math the fraction 5/6 means 5 and 6 tenths.
STEP 1:
find the sales tax (decimal form)
x= sales tax
Cost + (Cost * Sales Tax)= Total
plug in known numbers
$9.40 + ($9.40 * x)= $9.87
9.40 + 9.40x= 9.87
subtract 9.40 from both sides
9.40x= 0.47
divide both sides by 9.40
x= 0.47/9.40
x= 0.05 sales tax decimal form
STEP 2:
find sales tax percentage
= 0.05 * 100
or move decimal to the right two decimal places
= 5% sales tax percent form
ANSWER: The sales tax is 5% (or 0.05 in decimal form)
Hope this helps! :)
Answer:
-5
Step-by-step explanation:
When you subtract a negative you end up adding it instead
So hmmm check the picture below
in an isosceles triangle, two sides are equal, and thus the angles those twin legs make, are also twin angles
let's say the angle made is "a", so all internal angles will be 64 + a + a = 180
or 64 + 2a = 180
thus 2a = 180 - 64 => 2a = 116, thus a = 116/2
