Answer:

7. Orthocenter is on the triangle, at (0,0).

8. Orthocenter is outside the triangle, at (1,-5)

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given points:

Orthocenter is the intersection of altitudes. Altitude is perpendicular segment with one end on the opposite vertices.

Lets work out two altitudes and find their intersection.

Slope of JL

Equation of the line that is perpendicular to JL and passes through K(-3, 1). The line has the slope -1/3.

Slope of KL

Equation of the lines that is perpendicular to KL and passes through J(1, 3). The line has a slope -1/(-1/3) = 3

The orthocenter is the intersection of the lines:

The point is (0, 0) which overlaps with point L so it is on the triangle

Given points:

Lets work out two altitudes and find their intersection.

Slope of DE

Equation of the line that is perpendicular to JL and passes through F(1, 2). The line is vertical:

Slope of EF

Equation of the lines that is perpendicular to EF and passes through D(-3,-2)

The line has a slope -1/(4/3) = -3/4:

The orthocenter is the intersection of the lines:

The point is (1, -5) is outside the triangle

Answer:

2170000

Step-by-step explanation:

350(num of cherry trees)x6200(num of cherries per cherry tree)

The no. of cherries the farmer can harvest in a year will be 2170000 cherries.

It is given that farmer has 350 cherry tree on his farm and each tree yield 6200 cherries per year.

We have to find the no. of cherries the farmer can harvest per year.

What is the unitary method ?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

As per the question ;

A farmer has 350 cherry tree on his farm.

1 tree yield , no. of cherries = 6200 cherries per year

So;

In 1 year the no. of cherries the farmer can harvest;

=  6200 × 350

=  2170000 cherries

So ; farmer can harvest 2170000 cherries per year.

Thus , the no. of cherries the farmer can harvest in a year will be 2170000 cherries.

Answer:

4x^2 + 19x - 63

Step-by-step explanation:

3(x-3) = 3x - 9

x + 3x - 9 (x + 7)

(4x -9)(x + 7) = 4x(x) + 4x(7) - 9x - 9(7)

Answer:

mixed number form 1 1/9

decimal form 1.11111111111111 it goes on forever

percent form 111.111111111111% it goes on forever (again)

Step-by-step explanation:

i hope that helps!

Answer:

1  1/9

Step-by-step explanation:

10/9, you get 1 as the whole number.

You have a 1 left over when dividing 10 and 9. the 1 will be over 9.

Giving you 1 as the whole number and 1/9 next to it.

The explicit formula for a arithmetic sequence is a_n = a_1 + (n - 1)d.

We want to find a_21.

a_21 = 17 + (21 - 1)(10)

a_21 = 17 + (20)(10)

a_21 = 17 + 200

a_21 = 217

The 21st term is 217.

Answer:

r = 12.89

Step-by-step explanation:

18(2) + 15(3) = 81 = C

C = 2πr

81 = 2πr

81/2 = πr

r = 81/2π ≈ 12.89

Answer:

B)[tex]y=\frac{-2}{3}x-\frac{-13}{3}[/tex]

Step-by-step explanation:

2x +3y = 5

    3y = -2x + 5

Divide both sides by 3

[tex]\frac{3y}{3}=\frac{-2x}{3}+\frac{5}{3}\\\\y =\frac{-2}{3}x+\frac{5}{3}[/tex]

Parallel lines have same slope.

m = (-2/3) ; (-2 , -3)

y - y1 = m(x -x1)

[tex]y-[-3]=\frac{-2}{3}(x-[-2])\\\\y + 3 = \frac{-2}{3}(x +2)\\\\y + 3 =\frac{-2}{3}x + 2*\frac{-2}{3}\\\\y+3=\frac{-2}{3}x-\frac{4}{3}\\\\y=\frac{-2}{3}x-\frac{4}{3}-3\\\\y=\frac{-2}{3}x-\frac{4}{3}-\frac{3*3}{1*3}\\\\y=\frac{-2}{3}x-\frac{4}{3}-\frac{9}{3}\\\\y=\frac{-2}{3}x-\frac{-13}{3}[/tex]

Answer:

Does fill in!!!!

Step-by-step explanation:

1st substitute x with -4

5+3(-4)=-7

2nd step multiply

5-12=-7

3rd step subtract

-7=-7

so yes -4 is correct!!!!

Answer:

-4 is a solution

Step-by-step explanation:

x = -4

Equation:

5 + 3x = -7

Substitute x for -4

New equation:

5 + 3 x -4 = -7

Solve:

3 x -4 = -12

5 + -12 = -7

-7 = -7

Answer:

14

Step-by-step explanation:

Use rise over run, (y2 - y1) / (x2 - x1)

Plug in the points and simplify:

(y2 - y1) / (x2 - x1)

(70 - 56) / (5 - 4)

14 / 1

= 14

So, the slope of the line is 14.

m=14

Answer:

Niether

Step-by-step explanation:

the slopes arent opposite so they arent perpendicular, they arent the same so they arent parallel. they are niether due to thier slopes, but if they had the same slope, the y intercept would have to be different for them to be parrallel or else they would be the same line

Answer:

True because when you multiply the 2 by everything in the parentheses you get 4x + 6y which is 4x + 6y = 4x + 6y. and when you solve it you'll get 0 = 0

Answer:

2×2x +2×3y=

4x+6y

Step-by-step explanation:

you first clear the bracket as i have shown above

you use the one outside the bracket to multiply the ones inside the bracket and when you multiply you get 4x+6y
