Best luck with your studying

Answer 2

Answer:

(-1,3)

Step-by-step explanation:

3x + 6y = 15

6x + 6y = 12 Subtract

-3x = 3 Divide by 3

-x = 1 multiply by - 1

x = - 1

3x + 6y = 15

3(-1) + 6y = 15

-3 + 6y = 15 Add 3 to both sides

-3+3 + 6y = 15 + 3

6y = 18 Divide by 6

y = 18/6

y = 3

(-1,3)

Find the missing term in the geometric sequence. 180,___,5

Answers

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:

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

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

Step-by-step explanation:

Answer:

7. (0, 0) - on the triangle8. (1, -5) - outside the triangle

Step-by-step explanation:

Question 7

Given points:

J(1, 3), K(-3, 1), L(0,0)

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

m(JL) = (0 - 3)/(0 - 1) = 3

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

y - 1 = -1/3(x - (-3)) ⇒ y = -1/3x

Slope of KL

m(KL) = (0-1)/(0 - (-3)) = -1/3

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

y - 3 = 3(x - 1) ⇒ y = 3x

The orthocenter is the intersection of the lines:

-1/3x = 3x ⇒ x = 0 ⇒ y = 0

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

Question 8

Given points:

D(-3, -2), E(-2, -2), F(1,2)

Lets work out two altitudes and find their intersection.

Slope of DE

m(DE) = (-2 - (-2))/(-2 -(-3)) = 0, horizontal line

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

x = 1

Slope of EF

m(EF) = (2- (-2))/(1 - (-2)) = 4/3

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:

y - (-2) = -3/4(x - (-3)) ⇒ y = -3/4x - 17/4

The orthocenter is the intersection of the lines:

x = 1y = -3/4 - 17/4 = -20/4 = -5

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

find the value of x in the isosceles triangle shown below.
V80
V80

Answers

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

What is the slope of the line passing through

Answers

Answer:

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

In isosceles triangle JKL, JK KL. If the measure of
angle J is 47°, find the measure of angle K.
*Note: Do NOT include the degree in your answer.

Answers

Answer:

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°
