Step-by-step explanation:

Answer: the equation of this parallel line would be: Answer:  y = 5x - 6

Step-by-step explanation:

Slope of the parallel lines are same

So, m= 5

(3,9)

Equation: y - y1 = m(x -x1)

y - 9 = 5(x - 3)

y - 9 = 5x - 3*5

y -9 = 5x -15          {add 9 to both sides}

y - 9 + 9 = 5x - 15 + 9

y = 5x - 6

Step-by-step explanation:

Answer:

B. 600 ft

Step-by-step explanation:

The formula for the Perimeter of a right triangle = Side a + Side b + Side c

The perimeter of a right triangle is 60 feet

If the lengths of the sides of the triangle are each multiplied by 10, what is the perimeter of the new right triangle?

Hence, the perimeter of the new right triangle = 10 × 60ft

= 600ft

Option B is the correct Option.

Answer:

600

Answer:

[tex]y = -\frac{8}{x}[/tex]

Step-by-step explanation:

Given

Inverse Variation:

[tex]Points: \{(-1, 8), (4, -2), (-2, 4)\}[/tex]

Required

Determine the equation of the relation

An inverse relation is represented as:

[tex]y = \frac{k}{x}[/tex]

Where k = constant of variation

Make k the subject:

[tex]k = xy[/tex]

When x = -1, y = 8

So, we have:

[tex]k = -1 * 8[/tex]

[tex]k = -8[/tex]

When x = 4, y = -2

[tex]k = 4 * -2[/tex]

[tex]k = -8[/tex]

When x = -2, y = 4

[tex]k= -2 * 4[/tex]

[tex]k = -8[/tex]

From above calculations, we've established that:

[tex]k = -8[/tex]

Substitute -8 for k in [tex]y = \frac{k}{x}[/tex]

[tex]y = \frac{-8}{x}[/tex]

[tex]y = -\frac{8}{x}[/tex]

Hence, the equation is:

[tex]y = -\frac{8}{x}[/tex]

Answer:

the formula of a trapezoid is

H(a+b/2)

A= side 1 (usually the two parallel sides, choose one)

b= side 2 (same thing as A but the second line)

The h is height

So we fot 10 and 9

10+9=19

19/2=9.5

9.5*6

57

the Area is 57

Also you drew it wrong (look at image)

R<_-9

Answer:

19/1200

Step-by-step explanation:

Answer: Option A; x = 5, y = -13

Step-by-step explanation:

We have the equation:

(x + yi) + (4+9i) = 9-4i

Solving the left side we have:

x + y*i + 4 + 9*i = 9 - 4*i

(x + 4) + (y + 9)*i = 9 - 4*i

The real part is x + 4, and this must be equal to the real part in the right that is 9, then:

x + 4 = 9

x = 9 - 4 = 5

x = 5

And the imaginary part in the left needs to be equal to the imaginary part in the right, then:

y + 9 = -4

y = -4 - 9 = -13

y = -13

then the solution is x = 5, y = -13

The correct option is A

Answer:

1)y=-3+5x

2)y=5/2-1/2x

Step-by-step explanation:

for both equations

1) get your y by it self (subtract -5x and your new equation is now -y=-5x+3)

2)(reminder y can't be negative if it is negative) then you divide by -1 of both sides

3) your equation should now be y=5x-3

i think the answer is area = 1695.47 ft squared

Step-by-step explanation:

just do 45.7 x 37.1 since you’re finding area of a SQUARE which has all equal sides.

Answer:

add them up

Step-by-step explanation:

Answer:

a = 2

b = 4

Step-by-step explanation:

In parallelogram opposite sides are equal.

4a +  b  = 2a + 8

4a - 2a + b = 8

      2a + b = 8 -----------------(I)

             b = 8 - 2a

11b - 10a = 6b

11b - 6b -10a = 0

5b - 10a = 0 ---------(II)

Substitute b = 8 - 2a  in equation (II)

5*(8-2a) - 10a = 0

5*8 - 2a * 5 - 10a = 0

     40 - 10a - 10a = 0

      40 - 20a       = 0

                  -20a = - 40

                       a = -40/-20

                      a = 2

Plugin a = 2 in equation (I)

2*2 + b = 8

4 + b   = 8

       b = 8 -4

      b = 4

Answer:

A. c(r)=$19.5 if r < 2

c(r)=$19.5+(r-2) ($9) (1.045) if r ≥ 2

B. $29.78

Step-by-step explanation:

A. Based on the information given if we are to express the cost of the resumes which is c(r) algebraically as a piecewise function what we would have will be:

c(r)=$19.5 when r represent an INTERGER and is less than 2

c(r)=$19.5+(r-2) ($9) (1+0.045)

c(r)=$19.5+(r-2) ($9) (1.045) when r represent an INTERGER and is greater than 2

Therefore to express the cost of the resumes c(r) algebraically as a piecewise function will be: c(r)=$19.5 if r < 2

c(r)=$19.5+(r-2) ($9) (1.045) if r ≥ 2

B. Calculation for How much will 300 copies cost, including a sales tax of 4 1/2%

Cost of 300 copies=($19.5+$9)+($19.5+$9) (0.045)

Cost of 300 copies=$28.5+$28.5(0.045)

Cost of 300 copies=$28.50+$1.28

Cost of 300 copies=$29.78

Therefore How much will 300 copies cost, including a sales tax of 4 1/2% will be $29.78
