A-Y=5 less than twice X
B- (2,5), (4,4), (6,3), (8,2)
C- 5/2X-4
D- 3/2X-1
graph each answer choice and look at the slope of the line rise/run
the equation for answer choice A
is Y=5-(X•2)
the equation for answer choice B is
Y=-1/2X+6
the equation for C is Y=5/2x-4
and the equation for D is Y= 3/2X-1
the slope of A is -2/1
the slope for B is -1/2
the slope for C is 5/2
the slope for D is 3/2
the answer with the greatest slope is
5/2 the answer is C
Answer:
9 cars

8 minutes = 3 cars
8 minutes x 3=24 minutes
3 cars x 3 = 9 cars
Answer:
the distance between the other two subs is 207 meters
Step-by-step explanation:
Lara's radar on her submarine detects two other subs nearby. The first sub is 360m away, the second sub is 250m, and the angle between them is 34
Two sides and included angle is given
to find the opposite side of the angle we use cosine formula
b=250 , c=360 and angle A is 34 degrees
take square root on both sides to remove square
the distance between the other two subs is 207 meters
Answer:
The measure of angle x is
Step-by-step explanation:
we know that
In the right triangle of the figure, the tangent of angle x is equal to divide the opposite side to angle x by the adjacent side to angle x
so
Answer:
$227.64
Step-by-step explanation:
The relevant relations are ...
sales + tax = total
tax = 7% × sales
Using the second equation, we can write sales in terms of the tax as ...
sales = tax/0.07
Substituting this into the first equation gives ...
tax/.07 + tax = total . . . . . substitute for sales
tax(1/0.07 + 1) = total . . . . factor out tax
tax ((1 +.07)/.07) = total . . . simplify to a single fraction
Multiply by the inverse of this fraction:
tax = .07/1.07 × total = (7/107)($3479.64)
tax = $227.64
