In a class of 35 students, 19 take history and

saveliy_v [14]

Answer: 9

Step-by-step explanation:

If 19 students take history, 12 take economics and 5 take both:

19-5 = 14 students that take only history

12-5 = 7 students that take only economics

Therefore total number of students who either history, economics or history and economics: 14 + 7 + 5 = 26

Therefore students who take neither: 35 - 26 = 9

Answer:

$278.2 \: ft$

Step-by-step explanation:

Descended feet:

$94 \: s \times 3.3 \: \frac{ft}{s} \: = 310.2 \: ft$

Ascended feet:

$32 \: s \times 1 \: \frac{ft}{s} = 32 \: ft$

Total elevation:

$(310.2 - 32) \: ft = 278.2 \: ft$

What is the intersection of lines for the two equations y+3x=1 and y-6=2x?

netineya [11]

Answer:

Step-by-step explanation:

Let's reformat both equations so that $y$ is by itself on each side:

$y = -3x + 1$

$y = 2x + 6$

Since we $y$ isolated to one side in both equations, we know the right-hand sides must be equal:

$-3x + 1 = 2x + 6$

Solving for $x$ will give us the x-coordinate of the point of intersection:

$-5x = 5$

$x = -1$

Plugging in this x-coordinate to either of the above equations will give us the y-coordinate of the point of intersection:

$y = -3(-1) + 1$

$y = 4$

Therefore, the point of intersection is $(-1, 4)$
