Step b is wrong. The slope is the change in y over the change in x.

Step b should be (18- 8)/( 10-6)

= 10/4

= 5/2

Answer:

(4,-1)

Step-by-step explanation:

x is 4 y is -1

Answer:

(2,1)

Step-by-step explanation:

Let's solve your system by elimination.

6x−7y = 5;−4x+7y=−1

6x−7y=5

−4x+7y=−1

Add these equations to eliminate y:

2x = 4

Then solve2x = 4for x:

2x = 4

(Divide both sides by 2)

x = 2

Now let's plug x in to solve for y.

6x - 7y = 5

6(2) - 7y = 5

12 - 7y = 5

subtract 12 on both sides.

-7y = -7

divide both sides by -1

y = 1

Answer:

Step-by-step explanation:

total mass of people = 50× 5 = 250kg

height = 20m

force = mass × g = 250× 10 ( taking g= 10m/s²)

work done = force × distance

= 2500× 20

Answer:

(a)

perimeter = 2 + 8 + 4 + 7x + 4x

(b)

perimeter = 11x + 14

Given:

Length of a box is 9 inches, width is 2 inches and height is 1.5 inches.

The cost of silver coating is $2.50 per sq. inches.

To find:

The total cost of silver coating for the box.

Solution:

The total surface area of a cuboid is

[tex]A=2(lb+bh+hl)[/tex]

Where, l is length, b is breadth and h is height.

Putting [tex]l=9,b=2,h=1.5[/tex], we get

[tex]A=2(9\times 2+2\times 1.5+1.5\times 9)[/tex]

[tex]A=2(18+3+13.5)[/tex]

[tex]A=2(34.5)[/tex]

[tex]A=69[/tex]

So, the total surface area of the box is 69 square inches.

Cost of silver coating is $2.50 per sq. inches. So, the cost of silver coating for the box is

[tex]Cost=69\times 2.50[/tex]

[tex]Cost=172.50[/tex]

Therefore, the cost of silver coating for the box is $172.50.

Answer:

c, d.

Step-by-step explanation:

c; A vertical stretch by 4 will put the coefficient (in this case 4) in front of your original equation.

d; the negative in front of the whole equation (-4x) will flip the graph across the x-axis.

Step-by-step explanation:

(7/5 , 7/5)

Answer:

2y = -3x + 7

Step-by-step explanation:

(3, -1) and (-1, 5)

Slope:

m=(y2-y1)/(x2-x1)

m=(5+1)/(-1-3)

m=6/(-4)

m= -3/2

Slope-intercept:

y - y1 = m(x - x1)

y + 1 = -3/2(x - 3)

y + 1 = -3/2x + 9/2

y = -3/2x + 7/2

Standard form:

y = -3/2x + 7/2

3x + 2y = 7

2y = -3x + 7

Answer:

Florida = 345 feets

Delaware = 451 feets

Louisiana = 535 feets

Step-by-step explanation:

Given that:

Let :

Highest elevation in Florida, = x

Highest elevation in Delaware = x + 106

Highest elevation in Louisiana = x + 190

Sum of highest elevation in the 3 states = 1331 feets

Hence,

x + x + 106 + x + 190 = 1331

3x + 296 = 1331

3x = 1331 - 296

3x = 1035 feets

x = 1035 / 3

x = 345 feets

Hence,

Highest elevation in Florida, = x = 345

Highest elevation in Delaware = 345 + 106 = 451

Highest elevation in Louisiana = 345 + 190 = 535

Answer:

6

Step-by-step explanation:

Let x = number of hours.

Let y = cost.

The fixed cost is $11.

The cost per hour is $2.

For x hours, the cost per hour is 2x.

y = 2x + 11

23 = 2x + 11

12 = 2x

x = 6

Answer:

1 is 4x10^-9

2 is 4x10^10

3 is 5x10^7

4 is 2x10^-5

Step-by-step explanation:

The numbers as a single digit times a power of ten are ; 1. 4x10^-9, 2. 4x10^10, 3. 5x10^7, 4. 2x10^-5

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division. The Numbers constants, variables, operations, brackets can all be represented by mathematical symbol; which can also be used to indicate the logical syntax's order of operations and other features.

Therefore, each number as a single digit times a power of ten.

1. 0.000000043 is [tex]4 \times 10^{-9}[/tex]

2. 43560000.000 is[tex]4 \times 10^{10}[/tex]

3. 56.234567  is [tex]5 \times 10^7[/tex]

4. 0.00002346 is [tex]2 \times 10^{-5}[/tex]

Hence, The numbers as a single digit times a power of ten are ; 1. 4x10^-9, 2. 4x10^10, 3. 5x10^7, 4. 2x10^-5

Answer:

a) x <= 15 b) x > 16.5 c) x < 34.5 d) x =/= 23

Step-by-step explanation:

For a), there is a shaded region for where 15 is, and the number line is going towards the left, so x will be less than but also equal to 15

For b), there is not a shaded region for where 16.5 is, but the number line is going towards the right, so x will be greater than 16.5

For c), there is not a shaded region for where 34.5 is, but the number line is going towards the left, so x will be less than 34.5

For d), there is not a shaded region for where 23 is, but the number line is going everywhere else so it is x =/= 23(x does not equal to 23)

Answer:

52% Copper, 28% Zinc, 20% Nickel

Step-by-step explanation:

Copper is 13 out of 13+7+5 = 25

13/25 = 52%

Zinc is 7 out of 25 so 28%

Nickel is 5/25 = 20%

Answer:

120 cm cubed

Step-by-step explanation:

first we need to find the size of the triangular face. we can do this by taking the height and with of the base, multiplying them, then dividing by two (3*8)/2

which gives us 12, so now we multiply by 10 to get the volume of the full prism. 12*10=120

Answer:

B. This event will not happen.

C. The probability is 0.

Step-by-step explanation:

Only B and C can be answers because there are no green marbles so how can you select a green marble when there aren't any. The probility is 0 which means never going to happen.
