Answers

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)

Solve each system using substitution. Check your answer
x+3=y
3x+4y=7

Answers

Answer:

x = -5/7

y = 16/7

Step-by-step explanation:

3x + 4y = 7

3x + 4(x+3) = 7

3x + 4(x) + 4(3) = 7

3x + 4x + 12 = 7

7x + 12 = 7

7x + 12 - 12 = 7 - 12

7x = -5

7x ÷ 7 = -5 ÷ 7

x = -5/7

---------------------------------------

x + 3 = y

(-5/7) + 3 = y

16/7 = y

-----------------------------------------

3x + 4y = 7

3(-5/7) + 4(16/7) = 7

-15/7 + 64/7 = 7

7 = 7

The required value of the x and y by substitution method is -5/7 and 16/7 respectively.

Given,
System of equation
x+3=y
3x+4y=7

To solve using the substitution method.

What is the equation?

The equation is the values of two functions  that are equal.

What are functions?

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

x + 3 = y - - - - -(1)
3x + 4y = 7 - - - -(2)

from equation 1 substitute y in equation 2

3x + 4( x +3 ) = 7
3x + 4x + 12 = 7
7x = 7 - 12
7x = -5
x = -5/7
put this x on equation 1
-5/7 +3 = y
y = 16/7

Thus the required value of the x and y by substitution is -5/7 and 16/7 respectively.

Answers

Answer:

B. 60

Step-by-step explanation:

a quadrilateral always adds up to 360°. so you add up all angles then subtract your sum from 360. 140+80=220, now add angle U which is a congruent angle to angle s so 220+80=300. now 360-300=60

If 13% is lost by selling goods for Rs 1475, what would be the loss or gain if the goods are sold for Rs 1615?

Answers

Given:

Loss percent is 13%.

Selling price = 1475

To find:

The loss or gain if the goods are sold for Rs.1615?

Solution:

Let x be the cost price of goods.

Loss percent is 13% and selling price is 1475.

[tex]1475=x-\dfrac{13}{100}x[/tex]

[tex]1475=x-0.13x[/tex]

[tex]1475=0.87x[/tex]

[tex]\dfrac{1475}{0.87}=x[/tex]

[tex]1695.4023=x[/tex]

[tex]x\approx 1695.40[/tex]

The cost price of goods is 1695.40.

We need to find the loss or gain if the goods are sold for Rs.1615.

Cost price is greater than the selling price because 1695.40 > 1615. It means , it is a loss.

[tex]Loss=CP-SP[/tex]

[tex]Loss=1695.40-1615[/tex]

[tex]Loss=80.40[/tex]

The loss percent is

[tex]Loss\%=\dfrac{Loss}{C.P}\times 100[/tex]

[tex]Loss\%=\dfrac{80.40}{1695.40}\times 100[/tex]

[tex]Loss\%\approx 4.74\%[/tex]

Therefore, the loss is 80.40 and the loss percent is about 4.74%.

What is the equation of the line that passes through the point (−7,−1) and has a slope of 11?

Answers

Answer:

          y = 11x + 76

Step-by-step explanation:

The equation of a line with a slope of "a" and containing a given point (x₀, y₀) is:

y - y₀ = a(x - x₀)

a = 11,  x₀ = -7,  y₀ = -1

So:

y - (-1) = 11(x - (-7))  

y = 11x + 77 - 1

y = 11x + 76
