Answer:

The value of given expression is -22.

Step-by-step explanation:

We are given attached graph with the question.

The graph consist of plot for two function y = f(x) and y= g(x).

We need to evaluate the value of expression:

-3\times f(-8) + 7\times g(2)

From the given graph, it is easy to calculate value for f(-8) and g(2).

From graph:

f(-8) = -2

g(2) = -4

These values were obtained by looking the corresponding y-value for given x-values from the graph.

Putting the values in the expression, we get:

(-3)\times (-2) + 7\times (-4) = 6 - 28 = -22

Hence, the value of given expression is -22.

Answer:

-22

Step-by-step explanation:

-3•f(-8)+7•g(2)=

The value of f(x) at x=-8 is

f(-8) = -2

The value of g(x) at x=2 is

g(2) = -4

Substituting these values into the equations

-3 * -2 +7*-4

6 -28

-22

What k-1/3=5/6 equal ?
JulijaS [17]
The value of "K"

k -\frac{1}{3} = \frac{5}{6}

MMC (3,6)
3,6 | 3
1,2 | 2
1,1 |__ 3*2 = 6

Solving:
k -\frac{1}{3} = \frac{5}{6}
\frac{6k}{6} - \frac{2}{6} = \frac{5}{6}
cancel denominators (6)
6k - 2 = 5
6k = 5+2
6k = 7
\boxed{k =  \frac{7}{6} }

Points are: A= (-2,7)B= (3,5)C= (1,0) To show that the triangle is a right triangle, show that the sum of the squares of the len
Gala2k [10]

The sum of the squares of the lengths is 58

The square of length of the hypotenuse is 58

From the question, we have

AB² = (-2-3)² +(7-5)²= 25+4 =29

BC² = (3-1)²+(5-0)²=4+25=29

AC² = (-2-1)²+(7-0)² = 9+49 = 58

Here we can see that,

AB²+BC² = AC²

The sum of the squares of the lengths of two sides (the legs) equals the square length of the third side (hypotenuse).

the sum of the squares of the lengths = AB²+BC² =29+29 = 58

the square of length of the hypotenuse= 58

Pythagoras Theorem:

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side. When the positive integer sides of a right triangle (let's say sides a, b, and c) are squared, the result is an equation known as a Pythagorean triple.
