Answer:

<h2>steps A & B</h2><h2 />

Step-by-step explanation:

5x + 9 = 2x - 3

subtract 2x from both sides

5x - 2x + 9 = 2x - 2x - 3

simplify:

3x + 9 = -3

subtract 9 from both sides:

3x + 9 - 9 = -3 - 12

simplify:

3x = -12

divide 3 on both sides:

3 3

simplify:

x = -4

Reil [10]

Answer:

The area of the baseboard is $135\ m^2$

Step-by-step explanation:

We have,

Length of the bed, l = 15 m

Width of the bed, b = 9/10 m

It is required to find the area of the baseboard. It is a shape of rectangle. The area of a rectangular shape is given by :

$A=l\times b\\\\A=15\ m\times \dfrac{9}{10}\ m\\\\A=\dfrac{135}{10}\ m^2\\\\A=135\ m^2$

So, the area of the baseboard is $135\ m^2$

Write an equation of a line with the given slope and y-intercept (8,1)m=-1/2

Ganezh [65]

Slope intercept form is y=mx+b
first plug in m
y=-1/2X + b
now plug in the point (8,1) for the x and the y
1=-1/2(8) + b

now you need to solve for b
simplify
1=-4+ b
add 4
5=b

now that you know b
you can plug it into the equation along with the m

so the answer is
y=-1/2X + 5
