A wood frame costs $1.50. Use a property to write an equivalent expression for the cost of a wood frame.

1 answer:

6 0

Let the width of the frame = x
Let the cost of a linear foot of the frame = y
Let the inside dimension of the length of the frame = a
Let the inside dimension of the width of the frame = b.

The total length of the frame = 2*a + 4x
The total width of the frame = 2b

The total amount of the frame in feet is (2a + 4x + 2b)*y = Cost

Write an equation of a line that is parallel to the line whose equation is 3y=x+6 and that passes through the point (-3,4).

Monica [59]

The standard form of this equation is

$y=\frac{1}{3}x+2$

The slope of two parallel lines i the same, so the slope of the line we're looking for is also $\frac{1}{3}$

Since the line passes through $(-3,4)$ , the equation is:

$(y-4)=\frac{1}{3}(x+3)$

$\boxed{y=\frac{1}{3}x+5}$

S is the midpoint of RT. If RS = 7x-4 and ST = 5x+10, what is ST

Natali [406]

Answer: 45

Step-by-step explanation:

$RS=ST\\\\7x-4=5x+10\\\\2x-4=10\\\\2x=14\\\\x=7\\\\\implies ST=5(7)+10=45$
