How many solutions does the system of equations below have?

Mathematics

BaLLatris [955]3 years ago
6 0

Answer:

C:  none

Step-by-step explanation:

Here we have two separate functions named 'y.'  Eliminate 'y' temporarily by equating these functions together:

x + 2 = y = x - 1

Subtracting x from both sides, we get:

0 + 2 = y = 0 - 1, or

       2 = -1

This is never true, so C is the correct answer:  NO solutions.

An easier way in which to do this problem is to visualize the graphs of

y = x + 2 and y = x - 1.  The graphs are parallel straight lines; they never intersect, and therefore we can conclude "no solution."

The equation of a line is y=-5/8x
Lesechka [4]

Answer:

B)  slope of the line   \frac{-5}{8}  ;Y- intercept is none

slope of the line   m = \frac{-5}{8}

Y- intercept is none

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given equation of the line   y = \frac{-5}{8} x

The equation of the straight line in slope - intercept form

                        y = m x + c

                        y = \frac{-5}{8} x+0

slope of the line   m = \frac{-5}{8}

Y- intercept is none

What is the answer to x-5y=30 so I can graph it?
Dahasolnce [82]

Answer:

x + 5y = 30

x + 5(0) = 30

x1 = 30    y1 = 0

x + 5y = 30

1(0) + 5y = 30

y2 = 6    x2 = 0

(x1,y1) and (x2,y2)

(30,0) and (0,6)

What is the answer and how do I solve?
8_murik_8 [283]
Because it is a 90° angle and the legs are congruent, the legs intersect with the hypotenuse at the same angle, so the other, unnamed angle at the bottom left is equal to x.

Now we can state that:

2x + 90 = 180
2x = 90
x = 45

Samantha wants to use her savings of 1150 to buy shirts and watches for her family. The total price of the shirt she bought was
ioda

<u>Answer-</u>

<em>The maximum number of watches that Samantha come by with her savings is </em><em>10</em><em>.</em>

<u>Solution-</u>

The amount of money Samantha has in her savings account = $1150

She wants to buy shirts and watches.

Cost of one shirt = $84

Cost of each watch = $99

Let she can buy maximum of x watches, so the net price of the watches is $99x.

Then,

\Rightarrow 99x+84=1150\\\\\Rightarrow 99x=1150-84\\\\\Rightarrow 99x=1066\\\\\Rightarrow x=\dfrac{1066}{99}\\\\\Rightarrow x=10.77

As the number of watches can not be in fraction, so at most she can buy 10 watches.
