Answer:
$175
Step-by-step explanation:
Let x represent money saved by her in one month.
So money saved by her in one year (12 months) would be 
.
We can represent our given information as:
Therefore, she needs to save $175 per month.
You can think of midpoint as being an average.
Add the values and divide by 2.
(x1 + x2)/2, (y1 + y2)/2
(2 + 6)/2, (3 + 11)/2
(4,7) would be the midpoint
A polynomial with a degree of 3 is understood to have three zeroes or roots. In the given problem in 1, x3 + 6 x2 – 9x – 54, the roots of the polynomial using the calculator are B. B. 3, -3, -6. The same applies for number 2 given the polynomial x3 – 4x2 + 3x – 12. The answer in 2 is D. 4 years. The roots of the polynomial in 3 are:
<span>x1=−0.45117</span>
<span><span>x2</span>=1.77474</span>
<span><span>x3</span>=0.03821+0.70576∗i</span>
<span><span><span>x4</span>=0.03821−0.70576∗i. Hence there is A. 1 negative root.</span></span>
Answer:
15, 20, 25, 30
Step-by-step explanation:
If want to find the first multiple, we could actually use the equation: x + (x+5) + (x+5+5) + (x+5+5+5) = 90. After simplifying this term, we would get 4x+30 = 90 which then transforms into 4x=60 which simplifys to x = 15. Plug 15 into the original equation, and you would get the multiples 15 + 20 + 25 + 30 = 90.
