What is the solution of the linear-quadratic system of equations? { y = x 2 + 5 x − 3 y − x = 2

photoshop1234 [79]

Try substituting those values, and you will see they do not fit either equation.

looking at the 2nd equation, y = x+2, so

x+2 = x^2+5x-3

x^2 + 4x - 5 = 0

(x+5)(x-1) = 0

x = -5 or 1

so, y = -3 or 3

the solutions are thus (-5,-3)(1,3)

Hope this helps

Which of the following could be the system of nonlinear inequalities graphed below?

Ivan

Answer:

Option A.

Step-by-step explanation:

step 1

we know that

The equation of the solid line is

$y=5$

The solution is the shaded area above the solid line

The equation of the first inequality is

$y\geq 5$

step 2

The equation of the dashed line is

$y=x^{2} -5x+6$

The solution is the shaded area above the dashed line

The equation of the second inequality is

$y>x^{2} -5x+6$

therefore

The system of inequalities could be

$y\geq 5$

$y>x^{2} -5x+6$

astra-53 [7]

welll...you have there written just one relationship...it is berween 280 and 4 hours...you have to figure out speed:

$280 \div 4 = 70$

it is speed per hour

then you just connect time and speed:

140 - 2
280 - 4
350 - 5
420 - 6
560 - 8
700 - 10
