Answer:
C
Step-by-step explanation:
given - 2x < 10 ( divide both sides by - 2 )
Remembering that the symbol is reversed when multiplying/ dividing by a negative quantity.
x > - 5 ← note reversal of symbol
solution is {x | x > - 5 } → C
100 times (6+5)
100 times 11
100 groups of 11=1100
Hope I helped:)
For this unit conversion problem, you'll need to know:
1 m = 100 cm
Now let's convert with this conversion ratio!
First, you need to write to expressions to model each situation:
Plan A: 10+0.15x
Plan B: 30+0.1x
Next, set the expressions equal to each other and solve for x:
10+0.15x=30+0.1x
<em>*Subtract 0.1x from both sides to isolate the variable*</em>
10+0.05x=30
<em>*Subtract 10 from both sides*</em>
0.05x=20
<em>*Divide both sides by 0.05*</em>
x=400
The plans would have the same cost after 400 minutes of calls.
To find how much money the plans cost at 400 minutes, plug 400 into either expression. We'll use Plan A:
10+0.15(400)
10+60
70
The plans will cost $70.
Hope this helps!
Answer: p = 75 + 250
Equation of the situation, in slope-intercept form is given as .
Where,
b = y-intercept
m = slope
n = number of computers sold
p = total cost
All we need to find is the value of m and b.
Using two pairs from the table of values, (4, 550) and (6, 700):
Substitute n = 4, p = 550, and m = 75 in , and find the value of b.
Subtract 300 from each side
b = 250
Substitute m = 75, and b = 250 in
✅Equation that represents the situation would be:
