Answer:
Step-by-step explanation:
Driving 55mph for two hours, he would travel 110 miles
Driving 70mph for one hour, he would travel 70 miles.
Driving 50mph for two hours, he would travel 100 miles.
Total Distance would be 280 miles.
Average speed would be (55+70+50)/3 = 58mph
If he drove 280 miles at 70mph, it would take 4 hours
Distance = Rate X Time
Y
=
25
Explanation:
y
=
k
x
;where
x
and
y
are variables and
k
is constant
or
5
=
k
10
or
k
=
5
(
10
)
or
k
=
50
So Equation becomes
y
=
50
x
When
x
=
2
y
=
50
2
or
y
=
25
Answer:
A. Solution to but not to
Step-by-step explanation:
Given
Required
Is a solution?
implies that:
To check if it is a solution or not, we simply substitute 0 for x and for y in the given inequalities
becomes
This solution is true
becomes
This solution is not true because 0 is greater than 1.
Hence, option (A) is correct
Answer:
inches
Step-by-step explanation:
I suppose they are asking you for the length of the red part.
18 * = inches
1. <u>Plug in</u> " -2 " into f
f(-2) = 3 (-2) - 1
f(-2) = -6 - 1
f(-2) = -7
2. <u>Plug in</u> "5" into g
g(5) = -(5) + 6
g(5) = -5 + 6 = 1
3. <u>Add</u> what you got when you solved for <u>f(-2) and g(5) together</u>
f(-2) + g(5) = ?
f(-2) + g(5) = -7 + 1
f(-2) + g(5) = -6
Your answer is A
