Answer:

y= 1/2 x +6

Step-by-step explanation:

y-8= 1/2 (x-4)

y-8= 1/2 *x - 1/2*4

y= 1/2 *x - 1/2*4 +8

y= 1/2 *x - 2 +8

y= 1/2 *x +6

Answer:

18

Step-by-step explanation:

a + 7b + 4c = 2,

Multiply this equation by 9

9( a + 7b + 4c) = 2*9

9a + 63b +36c = 18

Rearrange the order

36c +9a +63b = 18

Answer:

18

Step-by-step explanation:

36c+9a+63b= collecting 9:

=9*(4c+a+7b)

so it is 4 times the given a+7b+4c which in the definition is equal to 2; so:

=9*(4c+a+7b)=9 * 2=18

The correct question is

 What value of b will

cause the system to have an infinite number of solutions?

For

y = 6x – b   and  -3x+(1/2)y=-3

 we have that

y = 6x – b   ---------> equation

1

-3x+(1/2)y=-3--------->  -6x+y=-6------ > -2x+y=-3------- > y=6x-6

y=6x-6------>

equation 2

 we know that

For the system to have an infinite number of solution,

equation 1 must be equal to equation 2

so

6x – b=6x-6-------> 6x-6x=b-6---------> b=6

 the answer is b=(6)

The value of b will cause the system to have an infinite number of solutions is 6

For the system of equations to have an infinite number of solutions, the system of equations must be similar

Given the system of equations:

y = 6x – b   and  -3x+(1/2)y= -3

y = 6x – b .................... 1

From the secind equation;

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

-6x+y=-6

-2x+y=-3

y=6x-6

y=6x-6

Equate with equation 1 to have:

6x - 6 = 6x - b

b = 6

Hence the value of b will cause the system to have an infinite number of solutions is 6

Answer:

x<11

Step-by-step explanation:

To solve this inequality, we must isolate the x. To do that, we divide both sides by 5. This gives us x<11. So all numbers less than eleven belong to the solution set of the inequality.

Answer:

All number less than 11.

Step-by-step explanation:

5x < 55

We just isolate x by dividing both sides by 5:

5x / 5 < 55/5

x < 11.

Answer:

B y=55

Step-by-step explanation:

The sum of the angles of a triangle a 180 degrees

40 + y + (y+30) = 180

Combine like terms

Subtract 70 from each side

70-70 +2y = 180-70

Step-by-step explanation:

Y=-x^2+6x-5

Y=3

a) Use substitution :

3 = - x²+6x- 5

x²- 6x+8 = 0

b) Factor your equation:

(x- 2)(x-4)=0

c) Identify the x-values of the solutions:

x-2=0 or x-4 =0

x=2 or x=4

d) Identify the solution to the system :

x=2       y=3

      and

x=4       y=3

The nonlinear system of equations can be solved by first substituting Y=3 into the other equation, then simplifying and factoring. The solutions for x are found by setting each factor equal to zero. The overall solutions to the system are (2,3) and (4,3).

To solve the given nonlinear system of equations we can use the substitution method. The equations given are:
Y=-x^2+6x-5 and Y=3.
We can start by substituting Y=3 in the first equation, which yields:
3=-x^2+6x-5. To rewrite this equation so one side is equal to 0, follow these steps:
-x^2+6x-5-3=0.
This simplifies to:
-x^2+6x-8=0.

Next, we can factor this equation. But it will be easier to factor if we multiply through by -1:
x^2-6x+8=0.
The factors of this equation are:
(x-2)(x-4)=0.

To find the x-values of the solutions, set each factor equal to zero:
x-2=0 or x-4=0.
Solving for x, we can see that it's values are x=2 or x=4.
Hence, the solution of the system are the ordered pairs (2,3) and (4,3).

Answer:

y = -3x - 5.

Step-by-step explanation:

y – y1 = m(x – x1)

The slope m =  rise /run = (4 - -5) / (-3 - 0)

= 9/-3

= -3.

Using the point (0, -5) and m =-3 in the point-slope:

y - -5 = -3(x - 0)

y + 5 = -3x

To find the profit for selling eggs, subtract the cost price from the selling price, resulting in a profit of Rs. 10 per dozen.

To calculate the profit or loss from buying and selling eggs, we need to follow a series of steps. First, we find the cost of buying the eggs, which is Rs. 120 per dozen. Then, we find the revenue from selling the eggs, which is Rs. 130 per dozen. The difference between these two amounts will give us the profit or loss made on each dozen of eggs sold.

The calculation is as follows:

Selling Price (SP) per dozen = Rs. 130

Cost Price (CP) per dozen = Rs. 120

Profit per dozen = SP - CP

Profit per dozen = Rs. 130 - Rs. 120 = Rs. 10

Therefore, for each dozen of eggs sold, there's a profit of Rs. 10.

y = money left in account

Then you must replace 145 (the money) for y and solve for x (the weeks)

145 = -27x + 577

145 - 577 = -27x + 577 - 577

-432 = -27x

Step-by-step explanation:

We need to find the value the function g(x) when x = 4, that is;

g(4)

In the first definition of the function, the value of x is strictly less than 4. Consequently, we shall use the second definition of the function to evaluate g(4)

In the second definition, g(x) is given as;

Q(x) = 0.5x + 10

plug in x = 4 and simplify;

Q(4) = 0.5(4) + 10

Q(4) = 12

Find the rate of change between first two ordered pairs and the second two ordered pairs:

1. Points (2,4) and (3,9). Rate of change:

[tex]\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{9-4}{3-2}=\dfrac{5}{1}=5[/tex]

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Let d be the total number of computer desks and c be the total number eof single drawer file cabinets.

1. A computer desk weighs 50 pounds, then d computer desks weigh 50d pounds. A single drawer file cabinet weighs 30 pounds, then c cabinets weigh 30c pounds. In total, a train car can hold 1500 pounds of cargo, so

50d+30c=1500

2.  A computer desk occupies a space of 4 cubic feet, then d computer desks occupy 4d cubic feet. A single drawer file cabinet occupies a space of 3 cubic feet, then c cabinets occupy 3c cubic feet. In total, a train car can hold 138 cubic feet of space, so

4d+3c=138.

Thus, we get a system of two equations:

Answer: 10 bags

Step-by-step explanation:

First we must calculate the field area. Assuming it is a rectangle then its area equals the product of its length times its width

[tex]A =360*160\\\\A = 57600 ft^2[/tex]

You use 8 pounds of fertilizer per 1,000 square feet

So the amount of fertilizer you should use is:

[tex]57,600 ft^2 * \frac{8\ pounds}{1,000\ ft^2} = 460.8\ pounds[/tex]

As the fertilizer comes in bags of 50 pound then you need

[tex]460.8\ pounds * \frac{1\ bag}{50\ pounds} = 9.2\ bags[/tex]

Since you can not buy 9.2 bags then we round up to the next whole number.

Finally you need 10 bags of fertilizer

Area = Length x width and is given as square units.

The book is 1 ft x 5/8ft

Area = 1 x 5/8 = 5/8 square ft.

The answer would be D) 5/8 ft^2

Ans.

7/12 , 2/3 , 5/6

Why:

If we give all the fractions the same denominator then the fractions are, 8/12 , 10/12 , 7/12. We then can easily see what is the order. Once ordered correctly, just simplifiy.

Answer:

7/12 , 2/3 , 5/6

Step-by-step explanation:

Firstly, give them a common denominator.

What do 3,6 and 12 all have in common? 12

So what we do to the bottom, we do to the top.

Multiply the 2/3 by 4 (3x4=12) to make 8/12.

Multiply the 5/6 by 2 (2x6=12) to make 10/12

7/12 already has 12 as the denominator.

Now order them.

7/12 , 8/12, 10/12.

Change them back to the original sums.

7/12 , 2/3 , 5/6
