X + 3y = −4 x + 5y = −6

Mathematics

lesya [120]2 years ago
5 0

For this case we must solve the following system of equations:

x + 3y = -4\\x + 5y = -6

We clear x of both equations:

x = -4-3y\\x = -6-5y

We match:

-4-3y = -6-5y\\-3y + 5y = -6 + 4\\2y = -2\\y = \frac {-2} {2}\\y = -1

We find the value of "x":

x = -4-3 (-1)\\x = -4 + 3\\x = -1

Thus, the solution of the system is:

(x, y): (- 1, -1)

Answer:

(x, y): (- 1, -1)

The answer is D. My dad taught me an easy way to solve those kind of problems.You need to do (60×20)÷100. And since 60 and 20 both have a zero and 100 has 2 zeros, u can cross out all the zeros and just do 6×2 and divide that by 1 and so 20% of 60 is 12. Hope this helped :)

Answer:

h=\frac{V}{\pi r^2}

Step-by-step explanation:

To write this equation with h isolated, we cancel everything else on the right hand side of the equals sign.  This means we cancel π and r².

Since both of these are attached to h by multiplication, we divide by both to cancel.  We can divide by both at the same time:

\frac{V}{\pi r^2}=\frac{\pi r^2h}{\pi r^2}\\\\\frac{V}{\pi r^2}=h

Which question should you expect to be answered with variable data?
Valentin [98]

Answer:

The correct answer is the last one.

Step-by-step explanation:

Variable data is any kind of information gathered that can be made into a chart or graph representing what was collected. In other words, the data collected must vary.

The first, second, and third answers cannot be made into a chart/graph as it would be a singular number, and not provide varying data (which is required to produce a graph/chart).

The last answer would be correct as one can create a chart as the data collected from that question would vary. For example, five family members could be born in July, six in August, and ten in October. The variable that is "varying" would be these months.

Hope this helps!
