Answer:

Step-by-step explanation:

Let the fishing rod be x

Let the fishing reel be y

2x+4y=183..(1)

3x+6y=489...(2)

Multiply (1) by 3

6x+12y=549...(3)

Multiply (2) by 2

6x+12y=978...(4)

Answer:

fishing rod = $78, fishing reel=$7

Step-by-step explanation:

A fishing rod: x

A fishing reel: y

2x+4y=184

6x+3y=489

Simplify.

x+2y=92

2x+y=163

Add the equations.

3x+3y=255

Multiply by 2/3.

2x+2y=170

subtract.

x=78

y=7

Question 3 of 10
MrMuchimi

Answer:

The point-slope form  of the line is:

y + 4 = 4(x+3)

Hence, option B is correct.

Step-by-step explanation:

We know the point-slope form of the line equation is

y-y_1=m\left(x-x_1\right)

where

  • m is the slope of the line
  • (x₁, y₁) is the point

Given

The slope m = 4

From the graph, we can take the point (-3, -4)

So, in our case:

(x₁, y₁) = (-3, -4)

m = 4

now substituting m = 4 and (x₁, y₁) = (-3, -4) in the point-slope form of the line equation

y-y_1=m\left(x-x_1\right)

y - (-4) = 4(x - (-3))

y + 4 = 4(x+3)

Therefore, the point-slope form  of the line is:

y + 4 = 4(x+3)

Hence, option B is correct.

  • The graph of the line is also attached.

If someone can answer this and explain it, I would really appreciate it, thanks.

Answer:

x = 13

Step-by-step explanation:

Now since the lines are parrarel, the intersection points are alternate to each other. Therefore, A = B.

Solve:

8x + 2 = 14x - 76

2 + 76 = 6x

78 = 6x

x = 13

Seb made a jump of two and a half meters Kirsty's jump was 10 centimeters longer how long was Kirsty's jump
hoa [83]
First of all, a meter is equal to 100cm.
1m=100cm

Seb made a jump of two and a half meters. (2 \frac{1}{2} or 2.5)
Multiply 100 by 2.

100*2=200

Now we need the half.
What is half of 100? 
50 is half of 100.

So, add 50 to the 200.

200+50=250

Kirsty's jump was 10 centimeters longer.

Add 10 centimeters to the 250 centimeters.
250+10=260

Kirsty's jump was 260 centimeters high, or 2.55 meters.
