Answer: $\Large\boxed{(-4,~-3)~\text{and}~(-2,~1)}$

Step-by-step explanation:

<u>Given the system of equation</u>

$1)~y=-(x+2)^2+1$

$2)~y=2x+5$

<u>Expand the parenthesis of the 1) equation</u>

$y=-(x+2)^2+1$

$y=-(x^2+4x+4)+1$

$y=-x^2-4x-4+1$

$y=-x^2-4x-3$

<u>Current System</u>

$1)~y=-x^2-4x-3$

$2)~y=2x+5$

<u>Substitute the y value of the 1) equation with the 2) equation</u>

$2x+5=-x^2-4x-3$

<u>Add ( x² + 4x + 3) on both sides</u>

$2x+5+(x^2+4x+3)=-x^2-4x-3+(x^2+4x+3)$

$2x+5+x^2+4x+3=0$

<u>Combine like terms</u>

$x^2+2x+4x+5+3=0$

$x^2+6x+8=0$

<u>Factorize the quadratic equation</u>

$(x+4)(x+2)=0$

$x=-4~\text{or}~x=-2$

<u>Substitute the x values into one of the equations to find the y value</u>

$y=2x+5$

$y=2(-4)+5=-8+5=-3$

$y=2(-2)+5=-4+5=1$

<u>Therefore, the two solutions are:</u>

$\Large\boxed{(-4,~-3)~\text{and}~(-2,~1)}$

Hope this helps!! :)

Examine the following expression.

svetoff [14.1K]

Answer:

True expressions:

The constants, -3 and -8, are like terms.

The terms 3 p and p are like terms.

The terms in the expression are p squared, negative 3, 3 p, negative 8, p, p cubed.

The expression contains six terms.

Like terms have the same variables raised to the same powers.

Step-by-step explanation:

The expression is:

p² - 3 + 3p - 8 + p + p³

False expressions:

The terms p squared, 3 p, p, and p cubed have variables, so they are like terms. (They don't have the same exponents)

The terms p squared and p cubed are like terms. (They don't have the same exponents)

The expression contains seven terms. (It contains 6 terms)
