Answer: (6, -6)
Step-by-step explanation:
so midpoint =([tex]\frac{X1+X2}{2}[/tex],[tex]\frac{Y1+Y2}{2}[/tex])
for x co ordinate
[tex]\frac{-2+X2}{2}[/tex]=2
-2+X=4 (X2=x co ordinate point for b, can be written as just x now)
X=6
x co ordinate of B= 6
y co ordinates of y
[tex]\frac{-8+Y2}{2}[/tex]=-7
-8+Y=-14
Y=-6
co ordinates B (6,-6)
for proof/extra explanation (NOT necessary for working):
[tex]\frac{Y1+Y2}{2}[/tex]
=[tex]\frac{(-2)+6, (-8)+(-6)}{2}[/tex]
=[tex]\frac{4, -14}{2}[/tex]
=(2,-7)
which is the midpoint M
What are the coordinates of this point?

Can someone help me with Q1 And Q2 please !!!!
Answer:
Q1.acceleration=3u/20
Q2.a=13.908m/s
b.50.069km/hr
Step-by-step explanation:
Q1.V=U+at
u=um/sv=4um/st=20sv=u+at
substituting we have a=3u/20m/s^2 in terms of u
Q2.velocity =distance/time
v=100/7.19=13.908m/s

The ratio of plates to cups is 10:14. If
there are 7 cups, how many plates
are there?
Answer:
Step-by-step explanation:
p:c=10:14
p/c=10/14
p/7=10/14
p=7(10)/14
p=5
Answer:
5 plates
Step-by-step explanation:
First, make two fraction bars, one with the ratio 10/14 the other with the top blank and 7 on the bottom. Next, find how much to multiply 7 by to get 14. Use the number you get to divide 10 by. Then you should get 5. Hope this helped!
7. Find the value of x 8. find the value of y
Answer:
x = 27.8
y = 35
Step-by-step explanation:
∡D ≅ ∡A, therefore:
65 = 2y - 5
70 = 2y
y = 35
EF ≅ BC, therefore:
2x + y = 90.6
2x + 35 = 90.6
2x = 55.6
x = 27.8

Priyanka drives at 45km/h and reaches Delhi in 5 hours.What time will she take to complete the same journey if she increases her speed by 5km/h ?
Answer: Increasing her speed by 5km/h, she will take 4.5 hours to complete the journey.
Step-by-step explanation:
Step 1
Speed= Distance / TIme
Given Speed = 45km/h
and Time = 5 hours
Distance covered = Speed x Time
= 45 km/h x 5 hours
=225 kilometres.
Step 2
Increasing her speed by 5km/h makes the new Speed = 45 +5 = 50 km/h
At the same Distance of 225 km
Therefore she will complete the journey in
Time = Distance/ Speed
=225km/ 50km/h
=4.5 hours

Given that lines q and m are parallel and are cut by two
different transversal lines, j and k, use angle relationships
to determine the measure of each numbered angle:
angle 1 = 180-110 = 70 degrees (linnear pair)
angle 2= 180-115 = 65 degrees (linnear pair)
angle 3 = angle 2 = 65 degrees (corresponding angles)
angle 4= 180 - angle 3 = 180-65 = 115 degrees (linnear pair)
(your teacher might not like this, depends on the cituation, but use 180 degrees in triangle to get 7)
angle 7 = 180 -angle1 -angle 2= 180-70-65= 45 degrees
angle 6 = angle 7 = 45 degrees ( vertical angles)
angle 8= 180- angle 7= 180-45 = 135 ( linnear pair)
angle 9 =angle 6 = 45 degrees (corresponding angles)
angle 5=angle 9=45 degrees (vertical angles)
2x + y = 20
6x – 5 y= 12
Answer:
hi
Step-by-step explanation:
We see a set of linear equations. Hence, a system of linear equations. So we solve them by process of elimination, multiplying the top equation by 5 to eliminate first such that
(2x+y=20)*5
6x-5y=12
-----------------------------------------
10x+5y=100
6x-5y=12
--------------------------------
16x = 112 .............After dividing 16 we get
x = 7
Now we plug x = 7 back into the original first equation to obtain the y value such that
2(7) + y = 20
12 + y = 20
-12 -12
------------------
y = 8
I hope this helped!

Find the area of a sector
Answer:
990 cm²
Step-by-step explanation:
Given ratio of radii = a : b , then
ratio of areas = a² : b²
Here
ratio of radii = 50 : 30 = 5 : 3 , then
ratio of areas = 5² : 3² = 25 : 9
let x be the area of sector DEF , then using proportion
[tex]\frac{25}{2750}[/tex] = [tex]\frac{9}{x}[/tex] ← [tex]\frac{ratio}{area}[/tex]
cross- multiply
25x = 24750 ( divide both sides by 25 )
x = 990
Area of sector DEF = 990 cm²

Which statement about this table of values is true?
A.Because the rate of change is constant, the function is linear
B.Because the rate of change is constant, the function is nonlinear
C.Because the rate of change is not constant, the function is linear
D.Because the rate of change is not constant the function is nonlinear
Answer:
D
Step-by-step explanation:
If something is not constant we know it is non-linear. We know this is not constant because when graphed, the line is not straight.
Answer:
D.
Step-by-step explanation:
Here the rate of change is not constant. For example:
10-5 / 20-17 = 5/3
13-10/23-20 = 3/3 = 1

Answer:
just do pythagorean theorem
Step-by-step explanation:
Answer:
Step-by-step explanation:
Remark
This is a Pythagorean Problem
Formula
a^2 + b^2 = c^2
a = 5
b = ?
c = 9
Solution
5^2 + b^2 = 9^2 Expand the givens
25 + b^2 = 81 Subtract 25 from both sides
25-25+b^2 = 81- 25
b^2 = 56
√b^2 = √56
b = √8*7
b = √2*2*2*7
b = 2 √2*7
b = 2 √14
