Determine whether the point (1, 1) is a solution to the system of equations. Explain your reasoning in complete sentences. graph

erastova [34]

The solutions to system of equations are the point of intersection of the graphs of the equations.
The point of intersection of the graphs of the given equation is (0, 2). Therefore, point (1, 1) is not a solution to the system of equation.

The Sum of twice a number and 5 is at most 15. What are the possible values for the number?

NISA [10]

Let's call that number x, twice the number will be 2x, sum of it and 5 is, 2x+5. So if this expression is at most 15, it means, it can be only less than 15 and equal to 15. Let's show this as an inequality.

$2x+5\le 15$

Let's solve.

$2x+5\le 15\\ \\ 2x\le 15-5\\ \\ 2x\le 10\\ \\ x\le \frac { 10 }{ 2 } \\ \\ x\le 5$

$x\quad \in \quad \left[ -\infty ,5 \right]$

If the number is a natural number. The values it can take is, $x\quad \in \quad \left[ 0,1,2,3,4,5 \right]$

AlladinOne [14]

Answer:

y = m x + b standard form of equation for straight line\

m = (y2 - y1) / (x2 - x1) = (20 - -8) / 17 - 1) = 28 / 16

m = 7 / 4
