write the slope-intercept form of the line that passes through the point (1,0) and is parallel to x-y=7. type your answer in the

Brilliant_brown [7]

Parallel lines have the same slope but different y intercepts.
turn x-y=7 into slope intercept form by isolating y which would be -y=-x+7
divide the equation by -1 in order to make y positive and you get y=x-7
So rewrite the equation with the same slope but this time solving for b
y=x+b
plug in your coordinates
0=1+b
subtract 1 from both sides
-1=b
so your equation would be
y=x-1

In a small town, there are 4 times as many left-handed males as there are left-handed females, and there are 3 times as many rig

horrorfan [7]

Answer:

(b) 24

Step-by-step explanation:

The given variable definitions and the given relationships let us write these statements:

LH males = 4 × LH females = 4x

RH females = 3 × RH males = 3y

LH males + RH males = 204 = 4x +y

RH females + LH females = 348 = 3y +x

Your favorite method of solving equations of this sort can tell you ...

(x, y) = (24, 108)

There are 24 left-handed females.

<em>Additional comment</em>

Other numbers involved here are ...

y = 108 . . . . right-handed males

204-108 = 96 . . . . left-handed males (=4×24)

348-24 = 324 . . . . right-handed females (=3×108)

If you want to solve the equations by hand, you can use substitution for y to get an equation in x:

3(204 -4x) +x = 348 ⇒ -11x = -264 ⇒ x = 24
