The lines are have one solution and are consistent and Independent.

Gaining values for x and y allows us to determine whether the pair of linear equations is consistent or inconsistent. The system is consistent if x and y both have the same value. When there are no x and y values that fulfil both equations, the system becomes inconsistent.

Given:

y = 0.5x

2y = x + 4

Now solving the Above Equation

2(0.5x) = x+ 4

x = x+ 4

0 = 4

and, [tex]a_1= 0.5, b_1= -1, c_1= 0\\a_2= 1, b_2 = -2, c_ 2 = 4[/tex]

Now, [tex]a_1/ a_2 = b_1/ b_2\neq c_1/ c_2[/tex]

Then, the lines are have one solution and are consistent and Independent.

Mahalia can make a total of 18 napkins using the fabric which she has bought.

The quantity of space enclosing a three-dimensional shape's exterior is its surface area.

In other meaning, if we say side square then it is an area of the square but for a cuboid, there are 6 faces so the surface area will be external to all 6 surfaces area.

Given that,

She has 12 inches wide and 6 yards long fabric.

Since 1 yards = 36 inches.

So,

6 yards = 6 × 36 = 216 inches.

Now,

The total surface area of napkins ⇒ 12 × 216

⇒ 2592 inch²

Area for 1 napkin = 1 foot × 1 foot

Since 1 foot = 12 inches

So,

Area for 1 napkin = 12 × 12 = 144 inch²

Number of napkins can be made = The total surface area of napkins / Area for 1 napkin

Number of napkins that can be made = 2592 inch² / 144 inch²

⇒ 18

Hence "Mahalia can make a total of 18 napkins using the fabric which she has bought".

Answer: The values of both x and y will be real numbers greater than or equal to 0

Step-by-step explanation: because pounds and price cannot be a negative amount here. So either you're buying 0 or buying more than 0.

The thing that best describes the values of x and y is that they will be real numbers greater than or equal to 0

This refers to the union of both rational and irrational numbers that can have negative or positive values.

From the given information:

Peaches are being bought and sold

There is no negative value used

The conclusion that can be reached as to the values of x and y is that they contain real numbers greater than or equal to 0

Answer:

[tex]\frac{1}{153}[/tex]

Step-by-step explanation:

There are a total of 7 + 9 + 2 = 18 balls in the vase, therefore, when not replacing the first ball, there would be 18 · 17 = 306 ways to pull 2 balls. There are 2 ways to choose the first black ball and then 1 way to choose the second black ball so there are 2 · 1 = 2 ways to choose 2 black balls. Therefore, the probability is 2 / 306 = [tex]\frac{1}{153}[/tex].

Answer:

h < 4

Step-by-step explanation:

Simplify both sides

-8h + 16 > -3h - 4

Add 3h to both sides

-5h + 16 > -4

Subtract 16 from both sides

-5h > -20

Divide both sides by -5

-20 divided by -5 = 4

Since you divided by a negative number, you change the inequality sign to < instead of >

Step-by-step explanation:

The solution to this problem requires that we find other units besides the given one

1. ft/sec

2. km/h

3.m/s

1. converting to ft/sec

1 mile is 5280 ft

[tex]=\frac{45mile}{hour}* \frac{5280feet}{1 mile} *\frac{1 hours}{3600 secs} \\\\=66 ft/sec[/tex]

2. converting to km/h

1 mile is 1.60934

[tex]=\frac{45mile}{hour}* \frac{1.60934km}{1 mile} *\frac{1 hours}{1hour} \\\\=72.42km/h[/tex]

3. converting to m/s

1 mile is 1609.34

Answer: Approximately 0.78388 seconds

==========================================

Explanation:

Plug in t = 0 to find that

h = -16t^2 - 64t + 60

h = -16(0)^2 - 64(0) + 60

h = 60

The starting height is 60 feet.

-----

Now plug in h = 0 and solve for t.

h = -16t^2 - 64t + 60

0 = -16t^2 - 64t + 60

-16t^2 - 64t + 60 = 0

From here use the quadratic formula

[tex]t = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\t = \frac{-(-64)\pm\sqrt{(-64)^2-4(-16)(60)}}{2(-16)}\\\\t = \frac{64\pm\sqrt{7936}}{-32}\\\\t = \frac{64+\sqrt{7936}}{-32} \ \text{ or } \ t = \frac{64-\sqrt{7936}}{-32}\\\\t \approx -4.78388 \ \text{ or } \ t \approx 0.78388 \\\\[/tex]

We ignore the negative t value as a negative time doesn't make sense.

The only practical answer is roughly t = 0.78388 seconds.

Answer:

Step-by-step explanation:

Since O is the center of the circle, from that point to any point that lies on the outside of the circle will have the same measure. That's worded weird. From point O to A, which is a radius, the length of that radius is 12. That means that the length from point O to any point on the outside of the circle will also measure 12. So from O to B is also 12. For y, we have a rule for when 2 lines tangent to a circle meet at a single point outside the circle. The 2 tangent lines are equal in length. So that means that if AC is 19.6, the CB is also 19.6. Your answer choice is 4.

Answer:

Step-by-step explanation:

Okay so solving an inequality is essentially the same as solving an expression, just with a different symbol.

We can first separate the x to the left and whole numbers to the right side.

TIP INPORTANT: Put your variable numbers on the left side and your whole numbers which are the numbers without variables on the right side

so,

4x ≤  10 + 2

which is,

4x ≤  12, therefore,

x ≤  3.

Hope this helps!

What is an Inequality Equation?

Equations and inequalities are both mathematical sentences formed by relating two expressions to each other. Where as in an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

4 x - 2 ≤ 10

Adding 2 on both sides , we get

4 x ≤ 12

Divide by 4 on both sides , we get

x ≤ 3

Hence , the solution is x ≤ 3

If you are asking me to combine the expressions, then we can combine like terms to get 19x-6

Step-by-step explanation:

Answer:

TU = 6

Step-by-step explanation:

Using the Segment Addition Postulate, we know that TU + UV = TV, and since UV = 6 and TV = 12, we know that TU + 6 = 12, therefore, TU = 6.

8x = 12

Divide both sides by 8

x = 12/8 = 3/2

2y + 10 = 22

Subtract 10 from both sides.

2y = 12

Divide both sides by 2

y = 6

6 + 3/2 = 7 1/2

Answer:

7.5 or 7½

Step-by-step explanation:

8x÷4 = 12÷4

2y + 10 = 22

2y = 12

y = 6

1.5 + 6 = 7.5 = 7½
