Answer:

The equation of the perpendicular bisector is y =  [tex]\frac{-1}{2}[/tex] x - 3

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

The rule of the slope is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where

∵ A line passes through points (-1, 5) and (-7, -7)

∴ x1 = -1 ad y1 = 5

∴ x2 = -7 and y2 = -7

→ Use the rule of the slope above to find the slope of the line

∵ m = [tex]\frac{-7-5}{-7--1}[/tex] = [tex]\frac{-12}{-7+1}[/tex] = [tex]\frac{-12}{-6}[/tex] = 2

∴ m = 2

→ Reciprocal the value of m and change its sign to find the slope of

  the line perpendicular line

∴ m⊥ = [tex]\frac{-1}{2}[/tex]

→ Substitute in the form of the equation above

∵ y = [tex]\frac{-1}{2}[/tex] x + b

∵ The ⊥ line is also the bisector of the given line, find the mid-point

   of the given line because it is also lying on the ⊥ line

∵ M = ([tex]\frac{-1+-7}{2},\frac{5+-7}{2}[/tex]) =  ([tex]\frac{-8}{2},\frac{-2}{2}[/tex]) = (-4, -1)

∴ M = (-4, -1)

→ Substitute the coordinates of M in the equation of the ⊥ line above

∵ x = -4 and y = -1

∴ -1 = [tex]\frac{-1}{2}[/tex] (-4) + b

∴ -1 = 2 + b

→ Subtract 2 from both sides

∴ -3 = b

→ Substitute the value of b in the equation

∴  y =  [tex]\frac{-1}{2}[/tex] x + -3

∴ y =  [tex]\frac{-1}{2}[/tex] x - 3

∴ The equation of the perpendicular bisector is y =  [tex]\frac{-1}{2}[/tex] x - 3

Answer:

yes it is an integer

Step-by-step explanation:

please mark as brainliest

Answer:

Step-by-step explanation:

It is an integer because integers are whole numbers. This means that it doesn't include decimals, fractions, and irrational numbers. Even though not all negative numbers are integers, this one is, and that is because it is not a decimal, fraction, or irrational number.

Hope this helps! ^^

Answer:

x=-27

Step-by-step explanation:

4/7x * 14x = 1/14(14x) + 5/2x(14x)

Multiply both sides by 14x

8 = x+35

-27 = x

Answer: Jana and Tim will only spend the same amount on purchase orders to their manufacturers when they each order products with a total purchase value of $100.

Step-by-step explanation:

Jana and Tim would only be incurring same amount when both total purchase is to a value of $100. This is so because by purchasing a goods worth same amount, they both end up incurring $15 dollar additional cost. Jana would spend $15 on shipping her goods, while Tim would pay $4 Handling fees and $11 dollar shipping fee which would also amount to $15. What this means is total spent for both Jana and Tim would amount to $115 each.

Answer:

y = 5x/4 + 10

Step-by-step explanation:

If two lines are parallel, the slopes are equal

The equation of a straight line is y = mx + c

where m is slope and c is y-intercept

So in this case 5/4 is also the slope m of the second line

we can write the equation as;

y-y1 = m(x-x1)

y-0 = 5/4(x + 8)

y = 5x/4 + 10

c. 5x4=20

4x4=16 items.

Answer:

The equation of the linear function is y = 3x + 3

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

The rule of the slope is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where

∵ A line passes through points (1, 6) and (2, 9)

∴ x1 = 1 ad y1 = 6

∴ x2 = 2 and y2 = 9

→ Use the rule of the slope above to find the slope of the line

∵ m = [tex]\frac{9-6}{2-1}[/tex] = [tex]\frac{3}{1}[/tex] = 3

∴ m = 3

→ Substitute the value of m in the form of the equation above

∴ y = 3x + b

→ To find b substitute x and y in the equation by the coordinates of any

   point on the line

∵ x = 1 and y = 6

∴ 6 = 3 (1) + b

∴ 6 = 3 + b

→ Subtract 3 from both sides

∵ 6 - 3 = 3 - 3 + b

∴ 3 = b

→ Substitute the value of b in the equation above

∴ y = 3x + 3

∴ The equation of the linear function is y = 3x + 3

Answer:

4.39 to 2DP.

Step-by-step explanation:

x * (x - 2) =  28

x^2 - 2x = 28

Solving by completing the square:

(x - 1)^2 - 1 = 28

(x - 1)^2 = 29

x = +/-√29 + 1

x = 6.38516, -4.38516

x must be positive so it = 6.38516.

The shortest side = x - 2 = 4.385.

Answer:

The equation of the line that passes through the points (-1,8) and (2,-4) is:

Step-by-step explanation:

Given the points

[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-1,\:8\right),\:\left(x_2,\:y_2\right)=\left(2,\:-4\right)[/tex]

[tex]m=\frac{-4-8}{2-\left(-1\right)}[/tex]

[tex]m=-4[/tex]

As the point-slope form of the line equation is

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope.

substituting the values m = -4 and the point (-1,8)

[tex]y-\(8\right=-4\left(x-\left(-1\right)\right)[/tex]

[tex]y-8 = -4(x+1)[/tex]

Add 8 to both sides

[tex]y-8+8=-4\left(x+1\right)+8[/tex]

[tex]y=-4x+4[/tex]

Therefore, the equation of the line that passes through the points (-1,8) and (2,-4) is:

Answer: <1 is 46

Step-by-step explanation: If 4x+10+2x-16=180 becuase they are same sided interior angle they have to equal 180. and if you do the process you get X=31 and if you plug it in you get <1=46 and to check it you have to plug it in the other and add thoses two up and see if you get 180. which it does.

Answer:

C. 300

We need to find the temperature that most resembles with the model

We can easily see the graph if we plot it using a calculator

f(t) = 349.2(0.98)^t

Case a.  0

Zero is only achievable as the cooling time goes to infinity. This is not the case.

Case b.  100

for f = 100,

t ≈ 61.6,

which is out of the values of the table

Not the correct option

Case c.  300

for  f = 300,

t ≈ 7.5,

which is in range with the values of the table

Step-by-step explanation:

We know if two line pass through each other that the opposite angles will always be equal. Do we know it is simalar and that it is angle angle (aa), not angle side angle (asa). And we can also figur out GHF is similar to KHJ because it is a mirror, unlike JHK.
