What is u in this equation? -17-u/3=-2

emmasim [6.3K]

What is u in this equation means: solve for u


 $-17- \frac{u}{3} =-2\\~\\-17- \frac{u}{3}+17 =-2+17\\~\\- \frac{u}{3} =15\\~\\- \frac{u}{3}*-3 =15*-3\\~\\u=-45$

Determine which point is the solution to the given system.

KatRina [158]

Answer:

Step-by-step explanation:

We equate both the y's and solve for x algebraically:

$-\frac{4}{7}x+16=-\frac{2}{7}x+12\\16-12=-\frac{2}{7}x+\frac{4}{7}x\\4=\frac{2}{7}x\\x=\frac{4}{\frac{2}{7}}\\x=14$

Now taking the value x= 14 and putting it in the 1st equation would give us y:

$y=-\frac{4}{7}x+16\\y=-\frac{4}{7}(14)+16\\y=8$

Hence the solution is (14,8), answer is D

How do the constant of proportionality and slope relate to the unit rate

Pepsi [2]

Answer:

When a relationship is proportional, all y over x ratios simplify to the slope of the line which is the constant of proportionality or the unit rate, with one as a denominator. Example: Consider the equation y = 60x. The slope is 60. The rate of change is 60 units for every one unit.

PLS HELP! WILL GIVE BRAINLIST!

Vlad [161]

Answer:

y = 3x

Step-by-step explanation:

y = 13

x= 4

here

y∝x

that is

y= k x where k is constant

Since the equation is in the form $y=kx$ we know that

$13=K×4$

$k=13/4=3.25$

so we can write this

y = 3.23 x ≅ 3x
