Write an equation of a line in a slope-intercept form that passes through (-2,1) with a slope of 5.
KonstantinChe [14]
If they give you a point and slope, use point slope form.
Then simplify to get slope intercept form (y = mx + b)
slope (m) = 5
(-2, 1)

y - y1 = m(x - x1)
y - 1 = 5(x + 2)
y - 1 = 5x + 10

y = 5x + 11

Help, please
Elanso [62]

Answer: 10.5 is my guess

Step-by-step explanation:

1. 30% = 8.4

   100      x

cross multiply

30(x) = 840

divide both sides by 30 = 28

2. 37.5% = y

     100     28

cross multiply

1050 = 100y

divide both sides by 100 = 10.5

Ella has 0.5 lbs of sugar. How much water should she add to make the following concentrations? Tell Ella how much syrup she will
shusha [124]
Concentration = [ (mass of sugar)/(mass of solution) ] * 100

=> mass of solution = mass of sugar * 100 / concentration

1) concentration 20%

mass of sugar = 0.5 lbs

=> mass of solution = mass of sugar * 100 / concentration = 0.5 lbs * 100 / 20

mass of solution = 2,5 lbs

mass of water = mass of solution - mass of sugar = 2.5 lbs - 0.5 lbs = 2.0 lbs

Answer: she must add 2.0 lbs of water and will obtain 2.5 lbs of syrup

2) concentration 25%

Follow the same procedure.

mass of solution = 0.5 lbs * 100 / 25 =

mass of solution = 2.0 lbs

mass of water = 2.0 lbs - 0.5 lbs = 1.5lbs

Answer: she has to add 1.5 lbs of water and will obtain 2.0 lbs of syrup

3) Same procedure

mass of solution = mass of sugar * 100 / concentration = 0.5 lbs * 100 / 1.5

mass of solution = 33.33 lbs

mass of water = 33.33 lbs - 0.5 lbs = 32.83 lbs

Answer: she has to add 32.83 lbs of water and will obtain 32.83 lbs of syrup

What is the solution to the system of equations below? Y=-1/4x+2 and 3y=-3/4x-6
fgiga [73]

<u>Answer:</u>

There are infinite solutions to the system of equations given

<u>Solution: </u>

The given equations given are,

y=-\frac{x}{4}+2------ (i)

3 y=-\frac{3 x}{4}-6---- (ii)

Now putting the value of (i) in (ii) we get,

3 \times\left(-\frac{x}{4}+2\right)=-\frac{3 x}{4}-6

\Rightarrow-\frac{3 x}{4}+6=-\frac{3 x}{4}-6

\Rightarrow\frac{3 x}{4}-\frac{3 x}{4}=-12

\Rightarrow0 \times x=-12

\Rightarrowx=(\frac{-12}{0})=\infty

So, there are <em>infinite solutions</em> to the system.
