Answer:
x = 25
Step-by-step explanation:
Since we are trying to multiply 4 by x, we have to divide both sides by 4 to find x.
100 divided by 4 is 25, so x is 25.
To check your answer, we can multiply 4 by 25.
4 × 25 is 100
So, the answer is 25.
Answer:
<h2> 2 trips</h2>
Step-by-step explanation:
first, we need to model an expression, the solve, say
let the total amount charged by taxi be y
and let the number of kilometers be x
y=2x+9
given that uber charges $5
then the number of taxi trips that will equal urber charge is
y=2x+9=5
5=2x+9
solving for x we have
2x+9-5=0
2x+4=0
2x=-4
x=-2
x=2 (x cannot be negative)
Supplements add up to 180°
so just subtract 164 from 180
180
<u>-164
</u> 16
It opens up
This is because the leading term is positive: 4x^2 is positive, therefore the parabola opens up
