Given linear function, y = -2/3X + 5 What is the slope?

Vikki [24]

Answer:

The slope is $-\frac{2}{3}$ .

Step-by-step explanation:

The equation is conveniently in slope-intercept form.

$y=mx+b$

m - slope

b - y-intercept

-2/3 is in m's spot, so it is the slope of the equation.

$y=\boxed{m}x+b\\\\y=\boxed{-\frac{2}{3}}x+5$

Hope this helps.

Will mark brainliest ONE question with picture included! no need to do part c :)

Answer:

x + y = 24

16x + 20y = 434

x = 11.5

y = 12.5

Step-by-step explanation:

Part A:

x + y = 24

16x + 20y = 434

Part B:

simplify the second equation to find a "kind of answer" to a variable,

so we could simplify it to either y = 21.7 - 0.8x or x = 27.125 - 1.25y

in this case we will use y = 21.7 - 0.8x

substitute your new value of y into the first equation:

x + (21.7 - 0.8x) = 24

now, we can solve this to find the actual value of x: x = 11.5

so plug in your real x value to the simplified second equation (y = 21.7 - 0.8x)

you get y = 12.5

this tells you how many hours the machine spent on making each type of item

12R If V= ---- (r+R) Make R the subject of the equation .

k0ka [10]

V= $\frac{12R}{r+R}$
note, r and R are differnt
so multipl both sides by (r+R)
V(r+R)=12R
distribute
Vr+VR=12R
minus VR from both sides
Vr=12R-VR
undistribute R
Vr=R(12-V)
divide both sides by (12-V)
$\frac{Vr}{12-V}=R$ or
$R= \frac{Vr}{12-V}$
