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.

Step-by-step explanation: Just make some draws of the number and colors of the marbles, and add the white marbles to the red ones, there is 6 of them, they take out of the bag two, so there are still being four, a hundred is all a number (?) so divided 100 % in 4/ there is 25, is D just take D. Sorry man im tired.

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:

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.

4th one: 2x times 18

Step-by-step explanation:

1: -4x + 2y + 10

2: -12a^2 + 20ab

3: i didnt know it sorry

4: x^2 - 9x + 18

all you need to do is the order of operations

Answer:

29.4%

Step-by-step explanation:

the whole cirlce is 360 degrees which means 100%

to find the percentage of the shaded area, multiply the degrees by 100

⇒ 10.6 x 100 = 10600

then take the product and divide by 360

⇒ 1060 ÷ 360

⇒ 29.44

round to the nearet tenth of a percent

⇒ 29.4

Answer:

86

Step-by-step explanation:

Since ∆JKL is an isosceles triangle, it's base angles (<L and <J) would be equal to each other.

<L is opposite to side JK, <J is opposite to side KL.

m<J is given as 47°. Therefore,

m<L = m<J = 47°

m<L = 47°

m<J + m<L + m<K = 180° (sum of triangle)

47° + 47° + m<K = 180° (substitution)

94° + m<K = 180°

m<K = 180° - 94°

m<K = 86°

Answer:

5x

Step-by-step explanation: x + y + 2x + 2y + 4x + 5z

Answer:

30.

Step-by-step explanation:

first term = a

3r term = ar^2

So here ar^2/ a  = r^2

r^2 = 5/180 = 1/36

r = 1/6

So missing term = 180 * 1/6 = 30.

Answer:

answer = 130 degree.

Step-by-step explanation:

I hope is correct.

Answer:

choice 2) angle DOC = 145 degrees

Step-by-step explanation:

angle ABD = 1/2(30 degree arc) = 15 degrees because of the inscribed angle theorem.

angle AOB = 180 - 20 - 15 = 145 degrees

angle DOC  = angle AOB because it is a vertical angle to 145 degrees.

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:

Option A. x = 8

Step-by-step explanation:

Please see attached photo.

From the attached photo,

we shall determine the value of y. This can be obtained by using pythagoras theory as illustrated below:

(√80)² = 8² + y²

80 = 64 + y²

Collect like terms

80 – 64 = y²

16 = y²

Take the square root of both side

y = √16

y = 4

Finally, we shall determine the value of x. This can be obtained as follow:

From the attached photo,

x = 2y

but:

y = 4

Therefore,

x = 2y

x = 2 × 4

x = 8
