Which system of equations has no solution? HELP ASAP!!!!!!

Answer:

0 makes the statement true.

explanation:

5+(3×n)=5

5 + 3n = 5

3n = 5 - 5

3n = 0

n = 0

check:

5+(3×0) = 5

5 + 0 = 5

5 = 5

Both sides equal, therefore statement true.

Answer:

Step-by-step explanation:

The absolute value function multiplies its argument by -1 if and only if that argument is negative.

  [tex]|x-120|=\begin{cases}-(x-120)&\text{for }(x-120) < 0\\(x-120&\text{for }(x-120)\ge0\end{cases}[/tex]

The first condition resolves to ...

  x -120 < 0   ⇒   x < 120 . . . . . matches the given condition x < -120

So, we can simplify the expression to ...

  -(x -120) = 120 -x . . . when x < -120

__

  [tex]|x-(-12)|=\begin{cases}-(x+12)&\text{for }(x+12) < 0\\(x+12)&\text{for }(x+12)\ge0\end{cases}[/tex]

The second condition resolves to ...

  x+12 ≥ 0   ⇒   x ≥ -12 . . . . . matches the given condition x > -12

So, we can simplify the expression to ...

  x +12 . . . when x > -12

Additional comment

You may have noticed that the function |x -120| translates the absolute value function 120 units to the right. The condition x < -120 puts the boundary at 120 unit to the left of 0, well within the area to the left of the vertex. This is illustrated by the attached graph.

Answer:

Step-by-step explanation:

Relationship Equation between time and shrimps cleaned : S = 4T; Relationship is inversely proportional; Unit rate of change = 4

Given : 4 Shrimps cleaned every minute.

So, Shrimps cleaned 'S' = 4 times minutes taken 'T' ; S = 4T

The relationship between variables is proportional, as the dependent variable (shrimps) is constant multiples times the independent variable (time), & their ratio remains constant.

It is directly proportional, as both variables (shrimps & time)  move in same direction. One variable increase or decrease, other variable same respectively.

Graph in this case is upward sloping curve from origin, because of  direct proportional relationship respectively.

Unit rate of change denotes constant magnitude of change in a variable with other variable. It is 4 in this case, as time increases the shrimps.

Answer:

Step-by-step explanation:

[tex]m\angle X = m\angle Z[/tex] (Opposite angles of a parallelogram)

[tex]\implies m\angle X = 70\degree[/tex]

In [tex]\triangle WXY[/tex]

WX = XY (given)

[tex]\implies m\angle XWY = m\angle XYW[/tex]

(Angles opposite to equal sides are equal)

[tex]m\angle XWY = x [/tex] (Given)

[tex]\implies m\angle XYW=x[/tex]

[tex]\implies x + x + 70\degree=180\degree[/tex]

(By angle sum postulate of a triangle)

[tex]\implies 2x =180\degree-70\degree[/tex]

[tex]\implies 2x= 110\degree[/tex]

[tex]\implies x= \frac{110\degree}{2}[/tex]

Answer:

410.0625 cm^2

Step-by-step explanation:

As this is a square, the length of all sides is equal to each other.

Then the length of one side is = 81cm/4 = 20.25cm

Then the area of the square is = 20.25cm * 20.25cm = 410.0625

Find the values of P for which the quadratic equation 4x²+px+3=0 , provided that roots are equal or discriminant is zero .

Let us Consider a quadratic equation αx² + βx + c = 0, then nature of roots of quadratic equation depends upon Discriminant (D) of the quadratic equation.

For equal roots

[tex]\quad\green{ \underline { \boxed{ \sf{Discriminant, D = β² - 4αc}}}} [/tex]

So,

[tex]\sf{ β² - 4αc = 0}[/tex]

Here,

Now,

[tex]\begin{gathered}\implies\quad \sf p²- 4 \times 4 \times 3 =0 \end{gathered} [/tex]

[tex]\begin{gathered}\implies\quad \sf p²- 48 =0 \end{gathered} [/tex]

[tex]\begin{gathered}\implies\quad \sf p²=48\end{gathered} [/tex]

[tex]\begin{gathered}\implies\quad \sf p=±\sqrt{48}\end{gathered} [/tex]

[tex]\begin{gathered}\implies\quad \sf p=±\sqrt{2 \times 2 \times 2 \times 2 \times 3} \end{gathered}[/tex]

[tex]\begin{gathered}\implies\quad \sf p=± 2\times 2\sqrt{ 3 }\end{gathered} [/tex]

[tex]\begin{gathered}\implies\quad \boxed{\sf{p=±4\sqrt{ 3 }}}\end{gathered} [/tex]

Thus, the values of P for which the quadratic equation 4x²+px+3=0 are-

4√3 and -4√3.

Answer:

he took 4hpurs to reach him at a destination of 60miles if he drove for additional 2hours that will be 80miles

Answer:

A 48 degrees B 88 degrees C 44 degrees

Step-by-step explanation:

All the sides of a triangle add up to 180 degrees.

Subtract the known side from 180. 180-48=132 degrees. That means 132 degrees is the total size of the unknown two angles. You can write that like this:

132=x+(x-44)

Simplify

132=2x-44

add 44

176=2x

Divide by 2

x = 88 degrees.

Now we know that angle B is 88 degrees. Now we just have to find angle C, which will be simple now that we know what x equals.

X-44

88-44

44 degrees

The length of CD is the number of units on segment CD

Using the assumed parameters, the length of segment CD is 3 units

The question is incomplete, as the length of segment CD cannot be explicitly calculated from the given parameters.

Using a general explanation, a possible way to calculate the length of segment CD is if triangles EFG and CDE are similar triangles where segment CD and EF are similar sides.

So, we have:

CD = k * EF

Where k is the scale factor.

Assume the scale factor is 1/3, the equation becomes

CD = 1/3 * 9

CD =3

Using the assumed parameters, the length of segment CD is 3 units

Answer:

852

Step-by-step explanation:

2 times 10 is 20

8 times 109 is 872

You subtract the two values, 872-20=852

If Florida has a population of about 2 X 10'. The Earth has a population of about 8 X 109. Then 852  times more populated is the Earth than Florida.

Two or more expressions with an Equal sign is called as Equation.

Given that

Florida has a population of about 2 X 10'.

The Earth has a population of about 8 X 109.

We need to find  how many times more populated is the Earth than Florida.

We know that

2 times 10 is 20

and  8 times 109 is 872

To calculate how many times more populated is the Earth than Florida. we just required to subtract 872 and 20.

You subtract the two values, 872-20=852

Hence About 852 times more populated is the Earth than Florida.
