. Here is an equation 2x + 9 = -15. Write three different equations that have the same solution as 2x + 9 = -15. Show or explain

Anettt [7]

Answer:

1. $x-3=-15$
2. $2x=-24$
3. $2x-3=-27$

Step-by-step explanation:

Given the following question:

$2x+9=-15$

To find three equations that have the same solution as the given equation we have to first solve the equation.

$2x+9=-15$
$9-9=0$
$-15-9=-24$
$2x=-24$
$2x\div2=x$
$-24\div2=-12$
$x=-12$

<u>Equation one:</u>
$x-3=-15$
$-3+3=0$
$-15+3=-12$
$x=-12$

<u>Equation two:
</u> $2x=-24$
$2x\div2=x$
$-24\div2=-12$
$x=-12$

<u>Equation three:</u>
$2x-3=-27$
$-3+3=0$
$-27+3=-24$
$-24\div2=-12$
$x=-12$

Hope this helps.

Write the equation of a line that is parallel to y = 1/2 x + 5

kumpel [21]

Answer:

y = 1/2x + 5

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

When 2 lines are parallel, they have the same slope.

Step 1: Define variables

Random point (2, 6)

<em>m</em> = 1/2

y = 1/2x + b

Step 2: Find <em>b</em>

6 = 1/2(2) + b

6 = 1 + b

5 = b

Step 3: Rewrite parallel linear equation

y = 1/2x + 5

Z to the 2nd+11 Z equals -21 over 4

VashaNatasha [74]

If you're asking us to solve for Z...
z² + 11z = -21/4
4z² + 44z + 21 = 0
Enter... *drumroll* the quadratic equation!
$z = \frac{-b +- \sqrt{b^{2}-4ac}}{2a}$
(that's a plus or minus, sorry)
$z = \frac{-44 +- \sqrt{44^{2}-4(4)(21)}}{2(4)}$
x = -0.5 or -10.5

Does this help? Is it too complicated? Do you have any questions?
