What is the solution to the system of equations? 2x – y = 7 y = 2x 3
velikii [3]

Answer:

I will assume the second equation is y=2x^3.  If it is y=2x+3 or y=2x-3, the lines will never intersect:  they have the same slope (2):

Step-by-step explanation:

2x – y = 7 can be rewritten as:  y = 2x -7.  It has a slope of 2.  The second equation, y = 2x 3, isn't clearly written.  If the 3 has a plus or minus sign, then the lines will never intersect:  they have the same slope, 2.

I'll assume the second equation is y=2x^3.

Heather was asked to graph 3x - y = -4 by using slope and y-intercept. Her graph is shown.
irakobra [83]
Hello! The y-intercept is (0, 4), because the line crosses 0 in the x-axis at that point. We can cross out C and D, because those don't show that. The slope is rise/run. You would go up 3, and go to the right once. If you need to, solve for slope by doing y2 - y1/ x2 - x1. Let's use the point (0, 4) and (1, 7) as an example. We would set it up like this: 7 - 4 / 1 - 0. Solving that would give us 3/1 or just simply three. The slope is positive 3 and the y-intercept is (0, 4). The answer is A.

A sequence is formed by adding 1 to each square number.
MrRa [10]

Answer:

32 nd term

Step-by-step explanation:

The formula for the sequence is

n² + 1 ( that is 1 added to each square number )

Equate to 1025 and solve for n

n² + 1 = 1025 ( subtract 1 from each side )

n² = 1024 ( take the square root of both sides )

n = \sqrt{1024} = 32
