Which is the equation of a line that passes through (1,8) and (6,4)

Sati [7]

Answer:

y = - $\frac{4}{5}$ x + $\frac{44}{5}$

Step-by-step explanation:

(6, 4)

(1, 8)

m = $\frac{8-4}{1-6}$ = - $\frac{4}{5}$

y - 4 = - $\frac{4}{5}$ ( x - 6 )

y = -  $\frac{4}{5}$  x +  $\frac{44}{5}$ ⇔ y = - 0.8x + 8.8

When placed end to end, three red rods are 2 cm longer than than 2 blue rods. Three blue rods are 2 cm longer than four red rods

Oxana [17]

Answer:

Red = 10 cm, blue = 14 cm

Step-by-step explanation:

Let the length of each red rod be r and each blue rod be b

Then we have:

3r - 2b = 2
3b - 4r = 2

Multiply the first equation by 3 and the second one by 2:

9r - 6b = 6
6b - 8r = 4

Add the equations to eliminate one of variables:

9r - 8r = 6 + 4
r = 10 cm

Find the value of b:

3*10 -2b = 2
30 - 2 = 2b
2b = 28
b = 14 cm

Let

x-------> amount of yards of fabric that Jessica used per curtain

we know that

The length of 6 identical curtains plus the length of the fabric remaining, must be equal to the total yards of fabric'
