Answer:

[tex]y = 9[/tex]

Step-by-step explanation:

1) Add 3 to both sides.

[tex]3y = 2y + 6 + 3[/tex]

2) Simplify 2y + 6 + 3 to 2y + 9.

[tex]3y = 2y + 9[/tex]

3) Subtract 2y from both sides.

[tex]3y - 2y = 9[/tex]

4) Simplify 3y - 2y to y.

[tex]y = 9[/tex]

Therefor, the answer is y = 9.

Answer:

3y-3=2y+6

3y-2y=3+6 (You will group like terms)

therefore,y=9

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

hi..

let total amount of money Darius's parents sent to the book fair is m then according to the question

m= 4 × $11.50

m= $46

So Darius parents sent $46 to the book fair to be split among 4 children in his family..

hope it helps:)

Answer:

10w ≥ 30

Step-by-step explanation:

First, the variable w represents the "sum of a number and 15", so we don't know the missing value. Therefore the first part is 10w. The inequality is ≥ because it represents "at least 30". Your inequality should be 10w ≥ 30

Hope this helps!

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

Answer:

-50x + 600 = 250

Step-by-step explanation:

10x + 60(10-x) = 250

10x + 600 - 60x = 250

-50x + 600 = 250

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:

Step-by-step explanation:

The triangle CHE is right, angle CHE is marked as right angle.

We have:

Use Pythagorean theorem to find the value of EH:

Substitute known values and solve for EH

h(-3)=-3

Answer:

m<A: 50

Step-by-step explanation:

Complementary angles mean that the angles add up to, or equal 90

4x + 6 + 4x - 4 = 90

8x + 2 = 90

8x = 88

x = 11

m<A:

4x + 6

4(11) + 6

Step-by-step explanation:

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:

Step-by-step explanation:

5x + 1/4 = 61/4

       -1/4     -1/4

5x = 15

/5     /5

x = 3

Answer:

x=3

Step-by-step explanation:

5x+1/4=61/4

5x=61/4-1/4(61/4-1/4, they have the same denominator so can subtract them with each other)

5x=60/4   (60/4=15)

5x=15

x=15/5

x=3

Tip :to check your answer simply plug in the  value and then solve the equation. If both the sides are equal to each other, the answer is most likely correct.

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.
