What value would make the equation 8x = -72 true?

Answer:

x = 1

y = -1

Step-by-step explanation:

-5x + 5y = -10

rewrite the order:

5y = 5x  - 10

6x + 5y = 1

rewrite the order:

5y = 1 - 6x

substitute for 5y:

5x - 10 = 1 - 6x

simplify:

11x = 11

x = 1

5y = 1 - 6(1) = -5

y = -1

Answer:

At the end of that period, 3,276,800 tonnes of fish could be caught in the North Sea.

Step-by-step explanation:

Given that 8 million tonnes of fish were caught in the North sea in 2005, if the catch is reduced by 20% each year for four years, to determine what amount can be caught at the end of this time the following calculation must be performed :

100 - 20 = 80

Year 0 = 8 million

Year 1 = 8 x 0.8 = 6.4 million

Year 2 = 6.4 x 0.8 = 5.12 million

Year 3 = 5.12 x 0.8 = 4,096 million

Year 4 = 4.096 x 0.8 = 3.2768 million

Thus, at the end of that period, 3,276,800 tonnes of fish could be caught in the North Sea.

disculpa pero creo que la segunda esta mal escrita

Answer:

Step-by-step explanation:

For this triangle, since the angle is included between 2 given sides, the formula will be:

[tex]A =\frac{1}{2}ab*ac*sin(angleA)[/tex]

Putting values where they belong:

[tex]A=\frac{1}{2}(10)(12)sin72[/tex]

Do all that in your calculator (in degree mode, NOT radian!) to get

A = 57.1 square cm

Answer:

  7 square units

Step-by-step explanation:

There are several ways the area of triangle EBD can be found.

We choose the latter.

__

Pick's theorem says the area of a polygon can be found as ...

  A = i + b/2 -1

where i is the number of grid intersection points interior to the polygon, b is the number of grid points intersected by the border.

The attached figure shows the lines EB, BD, and DE intersect one point in addition to the vertices. So, b=4. A count of the red dots reveals 6 interior points (i=6). So, the area is ...

  A = 6 + (4/2) -1 = 7

The area of ∆EBD is 7 square units.

Answer:

10 cm

Step-by-step explanation:

[tex]\boxed{area \: of \: traingle = \frac{1}{2} \times base \times height}[/tex]

Substitute known values into the formula:

41.5= ½ ×8.3 ×height

41.5= 4.15 ×height

height

= 41.5 ÷4.15 (÷4.15 on both sides)

= 10cm

Answer:

10 cm.

Step-by-step explanation:

You will first need the formula for finding the Area of a Triangle:

Area = 1/2(Base x Height)

Next, we need our known measurements to plug into the Equation:

41.5 Sq Cm = 1/2(8.3cm x Height)

After that, multiply the equation by 2

2 x 41.5 = (2 x 1/2) x (8.3cm x Height)

∨

83 sq cm = 8.3 cm x Height

Finally, divide your area by 8.3 cm:

83 / 8.3 = 10cm = Height

So, the answer is Height = 10 cm.

option B is your correct answer

Answer:

See attached.

Step-by-step explanation:

Answer:

y = -2x + 28

Step-by-step explanation:

Slope intercept form is-

y = mx + b

y = y coordinate

m = slope, the rise/run

x = x coordinate

b = the y-intercept, the place the line crosses the y-axis.

Now, fill in the formula with the proper information.

y = -2x + b    You can use the point (10, 8) for the x and y coordinates to find b

  8 = -2(10) + b     Now solve for b

  8 = -20 + b

+20  +20

28 = b                    Now substitute 28 in for b

y = -2x + 28

Answer:

y-8=-2(x-10)

Step-by-step explanation:

y-y1=m(x-x1)

y-8=-2(x-10)
