Which graph shows the equation V = 4 + 2t, where V is the total volume of water in a bucket and t is the elapsed time in minutes

kodGreya [7K]

1. Subtract 4 from both sides
v - 4 = 2t
2. Divide both sides by 2
v - 4/2 = t
3. Switch sides
t = v - 4/2

Write the equation of the line that passes through the points (-6,5) and (3,−5). Put your answer in fully reduced point-slope fo

elena55 [62]

Answer:

$\displaystyle y-5=-\frac{10}{9}(x+6)$

Or:

$\displaystyle y+5=-\frac{10}{9}(x-3)$

Step-by-step explanation:

We want to write the equation of a line that passes through the points (-6, 5) and (3, -5) in point-slope form.

Point-slope form is given by:

$y-y_1=m(x-x_1)$

Thus, first, we need to find the slope. We can use the slope formula:

$\displaystyle m=\frac{\Delta y}{\Delta x}=\frac{(-5)-(5)}{(3)-(-6)}=\frac{-10}{9}=-\frac{10}{9}$

Next, we can use either of the two given points. I'll use (-6, 5). So, let (-6, 5) be (<em>x₁, y₁</em>). Substitute:

$\displaystyle y-(5)=-\frac{10}{9}(x-(-6))$

Or, fully simplified:

$\displaystyle y-5=\frac{-10}{9}(x+6)$

Using the other point, we will acquire:

$\displaystyle y-(-5)=-\frac{10}{9}(x-(3))$

Or, simplified:

$\displaystyle y+5=-\frac{10}{9}(x-3)$

How much water do you need to add to make each concentration?<br> 1% sugar syrup using 12 g sugar

yulyashka [42]

Answer:

1188 grams of water

Step-by-step explanation:

x is the grams of water

so total is 12+x grams

sugar/total is 12/12+x

and 1% ratio is 12/12+x=1/100

so x would be 1188 grams of water.

Please help!!! Brainliest for whoever is right! What is the sum of the rational expressions below?

fenix001 [56]

Answer:

Step-by-step explanation:

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

Write all the numerators above the least common denominator

$\frac{(x + 1)(2x + 3) + 3 {x}^{2} }{3x(x + 1)}$

Multiply the parentheses

$\frac{2 {x}^{2} + 3x + 2x + 3 + 3 {x}^{2} }{3x(x + 1)}$

Distribute 3x through the parentheses

$\frac{2 {x}^{2} + 3x + 2x + 3 + 3 {x}^{2} }{3 {x}^{2} + 3x}$

Collect like terms $=\frac{5 {x}^{2} + 5x + 3 }{3 {x}^{2} + 3 x}$

Hope this helps...

Good luck on your assignment...
