Determine if the following system of equations has no solutions, infinitely many

Mathematics
1 answer:
Vesnalui [34]3 years ago
7 0

Answer:

The system has infinitely many solutions

Step-by-step explanation:

we have

5x+3y=9 ----> equation A

-10x-6y=-18 ----> equation B

Multiply by -2 both sides equation A

-2(5x+3y)=-2(9)

-10x-6y=-18 ----> equation C

Compare equation B and equation C

The equations are identical (is the same line)

therefore

The system has infinitely many solutions

Is a consistent dependent system

Answer:

Step-by-step explanation:

Given that among 500 freshmen pursuing a business degree at a university, 315 are enrolled in an economics course, 213 are enrolled in a mathematics course, and 123 are enrolled in both an economics and a mathematics course.

315+213-123 =405

Out of 500 students 405 have taken either Math or Economics

c) student who have taken neither = 500-405 =95

Exactly one course is either math or economics - both

= 405-123 = 282

If an image of a triangle is congruent to the pre-image, what is the scale factor of the dilation?
zhannawk [14.2K]

Answer:

1

Step-by-step explanation:

A dilation of .1 or 1/2 would decrease the size. Since the numbers are smaller than zero the triangles would no longer be congruent. A dilation of 10 would increase the size of the triangle, causing the triangles to no longer be congruent. A scale fact of one is equivalent to the same size because 1 does not increase or decrease the size.

Write the series using summation notation. Then find the sum of the series.
ivolga24 [154]

Hello, please consider the following.

\displaystyle 1+2+3+...+12=\sum_{k=1}^{k=12} {k}=\dfrac{12*13}{2}=6*13=78

For the second we will need to put on the same denominator.

\displaystyle \dfrac{1}{2}+\dfrac{1}{4}+...+\dfrac{1}{14}=\sum_{k=1}^{k=7} {\dfrac{1}{2k}}\\\\=\dfrac{1}{2}\dfrac{420+210+140+105+84+70+60}{5*7*3*2*2}\\\\=\dfrac{1}{2}\dfrac{1089}{420}\\\\=\dfrac{1089}{840}=1.296429...

Thank you.
