Solve the system of linear equations by substitution.<br><br> y = 2x + 8<br> y = -2x

posledela

Answer:

(- 2, 4 )

Step-by-step explanation:

y = 2x + 8 → (1)

y = - 2x → (2)

substitute y = 2x + 8 into (2)

2x + 8 = - 2x ( add 2x to both sides )

4x + 8 = 0 ( subtract 8 from both sides )

4x = - 8 ( divide both sides by 4 )

x = - 2

substitute x = - 2 into (2)

y = - 2(- 2) = 4

solution is (- 2, 4 )

WILL GIVE BRAINLIEST!!<br><br> Which equations are correct?<br><br> Select each correct answer.

solong [7]

To multiply these expression, multiply the numeric parts, and sum the exponents of the literal parts (because the variable is the same: we're using the power property $a^b\cdot a^c = a^{b+c}$ ).

So, you have:

$3z^7 \cdot (4z^2) = 3\cdot 4 \cdot z^{7+2} = 12z^9$
$6a^5 \cdot (6a^5) = 6\cdot 6 \cdot z^{5+5} = 36z^{10}$
$6b^4 \cdot (-3b^4) = 6\cdot (-3) \cdot b^{4+4} = -18b^8$
$5x^4 \cdot (4x^2) = 5\cdot 4 \cdot x^{4+2} = 20x^6$
