Answer: y = (-1/2)x + 8.5

Step-by-step explanation:

A line perpendicular would have a slope that is the negative reciprocal of the given equation.

In this case, the slope is 2, so the perpendicular equation's slope would be -1/2.

We plug in (1, 8) to find b, or the y intercept.

8 = (-1/2)(1) + b

b = 8.5

So the equation would be:

y = (-1/2)x + 8.5

5 + 4x = -11​

Answers

Answer:

x=-4

Step-by-step explanation:

5+4x=-11

4x=-11-5

4x=-16

x=-16/4

x=-4

5+4(-4)=-11

5-16=-11

-11=-11

Answer:

x = -4

Step-by-step explanation:

5 + 4x =  -11

4x = -11 - 5

4x = -16 (Divide 4 both sides)

x = -4

5 + 4x =  -11

5 + 4(-4) = -11

5 - 16 = -11

-11 = -11

Answers

Answer:

162°

Step-by-step explanation:

To convert from radian to degree measure

degree measure = radian measure × [tex]\frac{180}{\pi }[/tex] , then

degree = [tex]\frac{9\pi }{10}[/tex] × [tex]\frac{180}{\pi }[/tex] ( cancel π and 10/ 180 to simplify )

            = 9 × 18

Find the interior angle sum of this polygon.

Can someone help????

Answers

Answer:  1440 degrees

===================================================

Explanation:

See the diagram below. It shows there are 10 sides, so n = 10.

We'll plug this value of n into the formula below to find the sum of all ten interior angles

S = sum of interior angles

S = 180(n-2)

S = 180(10-2)

S = 180(8)

S = 1440 degrees

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

A different approach:

Let's assume this polygon is a regular polygon. This means each angle is congruent to one another.

We have n = 10 sides, so each exterior angle is E = 360/n = 360/10 = 36 degrees.

Each interior angle adjacent to this 36 degree exterior angle is

180-E = 180-36 = 144 degrees

Since we have 10 equal angles of 144 degrees each, so overall the interior angles add to 10*144 = 1440 degrees

Side note: if this polygon is not a regular polygon, then this section does not apply. You would use the first method instead.

The table below gives the dimensions of a bridge and a scale model of the bridge.
Find the scale factor of the model to the real bridge.
Write your answer as a fraction in simplest form.

Answers

Answer:

Scale factor = [tex]\frac{1}{5}[/tex]

Step-by-step explanation:

Formula for the scale factor is,

Scale factor = [tex]\frac{\text{Dimension of the model}}{\text{Dimension of the original}}[/tex]

                    = [tex]\frac{\text{Dimension of the model}}{\text{Dimension of the bridge}}[/tex]

                    = [tex]\frac{\text{Width of the model}}{\text{Width of the bridge}}[/tex]

                    = [tex]\frac{7}{35}[/tex]

                    = [tex]\frac{1}{5}[/tex]

Therefore, scale factor of the model to the real bridge = [tex]\frac{1}{5}[/tex]

A = 2^3 x 3 x 5
B = 22 x 3 x 52
(b) Write down the highest common factor (HCF) of A and B.​

Answers

Answer:

Step-by-step explanation:

B = 22 × 3 × 52?—or is it supposed to be

B = 2² × 3 × 5² ?

A = 2² × 3 × 5

B = 2² × 3 × 5²

GCF = 2² × 3 × 5 = 60

A = 2² × 3 × 5

B = 22 × 3 × 52 = 2³ × 3 × 5 × 11 × 13

GCF = 2² × 3 × 5 = 60

Subtract seven from both sides. After you do that, simplify, then divide both sides by -4.

Also, quadractic bit of it is x = 3i + 3, x = -3i + 3.

Answer:

x=3+3i, 3-3i

Step-by-step explanation:

-4(x-3)²+7=43

(x-3)(x-3)= x²-6x+9

-4(x²-6x+9)+7=43

-4x²+24x-36+7=43

-4x²+24x-29=43

-4x²+24x-72=0

-x²+6x-18=0
