Answer:

We can now prove Euler's formula (v − e + f = 2) works in general, for any connected simple planar graph. Proof: by induction on the number of edges in the graph. Base: If e = 0, the graph consists of a single vertex with a single region surrounding it. So we have 1 − 0 + 1 = 2 which is clearly right.

A granola bite contains 27 calories. Most of the calories come from $$ grams of carbohydrates. The rest come from other ingredie

Yakvenalex [24]

Answer:

c = 5.5

Step-by-step explanation:

c represents the grams of carbohydrates

27 is the total number of calories that are received by the granola bite.

4 is the number of calories from 1 gram of carbohydrates and

5 is the number of calories that are received from other ingredients.

Answer of Part a:

5 is the number of calories that are received from other ingredients.

Part b:

take left hand side (LHS) and put values of c = 8 and 3 one by one.

So, LHS becomes:

4 \times 8 + 5 = 37 4 \

times 3 + 5 = 17

So, Priya is correct that neither 8 or 3 could be solution.

Part c:

So, solution to the equation is: c = 5.5

Construct the triangle ABC using as coordinates of its vertices points A(−3, 0), B(4, 5), C(0, −4). Find the coordinates of inte

Mnenie [13.5K]

Plot all points on the coordinate plane and combine these points by lines to get triangle ABC (see attached picture for details).

Write the equation of side AB:

$\dfrac{x-(-3)}{4-(-3)}=\dfrac{y-0}{5-0} ,\\ \\\dfrac{x+3}{7}=\dfrac{y}{5},\\ \\y=\dfrac{5}{7}x+\dfrac{15}{7}.$

To find y-intercept you have to substitute x=0, then:

$y=\dfrac{5}{7}\cdot 0+\dfrac{15}{7}=\dfrac{15}{7}=2\dfrac{1}{7}.$

The point $\left(0,2\dfrac{1}{7} \right)$ is the point where line AB intersects y-axis.
