Answer:
Option D. No solutions
Step-by-step explanation:
we have
-----> equation A
----> equation B
Multiply by -3 both sides equation A
-----> equation C
Compare equation B and equation C
Equation B and equation C are parallel lines with different y-intercept
<u><em>Verify</em></u>
For x=0
<em>Equation C</em>
----->
The y-intercept is the point (0,0.5)
Equation B
----->
The y-intercept is the point (0,-0.5)
therefore
Lines do not intersect
The system has no solution
see the attached figure to better understand the problem
The lowest (or least) common denominator also written as LCD is the smallest of all the possible common denominators, where t<span>he </span>denominator<span> is the bottom number in a fraction.
</span>We should find the lowest common denominator of (p+3)/(p^2+7p+10) and <span>(p+5)/(p^2+5p+6).
</span><span>p^2+7p+10 can be written as a product: (p+5)(p+2)
</span>p^2+5p+6 <span>can be written as a product: (p+3)(p+2)
</span>So, we should find the LCD for (p+5)(p+2) and (p+3)(p+2). The smallest possible number that can be divided with both of them is:<span>(p + 5)(p + 2)(p + 3)
Solution C.</span>
Answer: Option D
D. 880 = 45d + 70; 18 days
Step-by-step explanation:
We know that the cost of preschool is $ 45 per day plus a monthly fee of $ 70.
We also know that a total of $ 880 was paid last month
To write an equation that represents this situation, let us call d the number of days that Barry attends school
So the cost was:
Now we solve the equation for the variable d
The answer is the option D
Answer:
False
Step-by-step explanation:
I am guessing 76.9 because it is closer to 77, but both of them round up
