y=5x+b=>2=5*2+c=>c=-8

So y=5x-8

$\text{Given that,}\\\\(x_1,y_1) = (2,2), ~ \text{and}~ (x_2,y_2) = (3,7)\\\\\text{Slope, m =} \dfrac{y_2-y_1}{x_2-x_1} = \dfrac{7-2}{3-2} = \dfrac 51 = 5\\\\\text{Equation with given points,}\\\\y-y_1 = m(x-x_1)\\\\\implies y-2= 5(x-2)\\\\\implies y -2 = 5x-10\\\\\implies y = 5x -10 +2\\\\\implies y = 5x -8\\\\\\\text{It is now in a form of y = mx +c}$

Candace ate 3 over 4 cup of cereal. The box of cereal states that one serving of cereal is equal to 2 over 3 cup. Which fraction

choli [55]

Answer: Candace ate $\dfrac9{12}$ servings.

Step-by-step explanation:

Given: Candace ate $\dfrac34$ cup of cereal.

The box of cereal states that 1 serving of cereal = $\dfrac23$ cup.

i.e. 1 cup = $\dfrac32$ servings [Multiply $\dfrac32$ both sides]

⇒ $\dfrac{3}{4}$ cup = $\dfrac34\times\dfrac32$ servings

= $\dfrac9{12}$ servings [which is the number of servings she ate]

Hence, Candace ate $\dfrac9{12}$ servings.

At north shire high school 87.5% of the teachers have a masters degree. If there are 128 teachers, how many have a masters degre

Radda [10]

We have been given that at north shire high school 87.5% of the teachers have a masters degree. Total number of teachers is 128.

Let us find how many teachers have a masters degree.

$\text{Teachers hold masters degree }=\frac{128\times 87.5}{100}$

$\text{Teachers hold masters degree }=1.28\times 87.5$

$\text{Teachers hold masters degree }=112$

Therefore, 112 teachers have a masters degree.
