2(x+3) = 2x+8
2x+6=2x+8
2x-2x=8-6
0=-2
hence question isn't correct
Answer:
No solution/ Trick Question

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 triangleStep-by-step explanation:
Question 7Given 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) = 3Equation 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 = -1/3xSlope of KL
m(KL) = (0-1)/(0 - (-3)) = -1/3Equation 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 = 3xThe orthocenter is the intersection of the lines:
-1/3x = 3x ⇒ x = 0 ⇒ y = 0The point is (0, 0) which overlaps with point L so it is on the triangle
Question 8Given 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 lineEquation of the line that is perpendicular to JL and passes through F(1, 2). The line is vertical:
x = 1Slope of EF
m(EF) = (2- (-2))/(1 - (-2)) = 4/3Equation 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 - 17/4The orthocenter is the intersection of the lines:
x = 1y = -3/4 - 17/4 = -20/4 = -5The point is (1, -5) is outside the triangle

Answer: #4 is b
Step-by-step explanation:
What is the slope of the line passing through
(4,56) and (5,70)
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.
Answer:
m=14

Write an algebraic expression with 3 terms, at least one coefficent of 5 and 2 different variables.
Answer:
3+5y+3x-(26-3)
Is 2(2x + 3y) = 4x + 6y true or false and how do you know?
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
Step-by-step explanation:
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

help me with this please
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!

4) Darius's parents sent money to the book fair to be split among the four children in his family. After they gave the money to the cashier, she told each child they had $11.50 to spend. Write and solve an equation to show the total amount of money Darius's parents sent to the book fair.
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..

Are the lines parallel, perpendicular, or neither show work cause I need to understand this
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:
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.

What’s the measurement answer?
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
