plz show how to slove this!

Step-by-step explanation:

First we solve it.

I'll use substitution.

In the first equation y equals -2x+2 so we can apply that to the second equation

2y + 4x = 4

2(-2x+2) + 4x = 4

distribute

-4x+4+4x=4

simplify

4=4

To figure out how many solutions it has:

•If both side of the equal sign are exactly the same: Infinitely many

ex: 6x=6x

•If both sides of the equal sign do not match when completely simplified: No solutions

ex: 3x=-5x

•If it creates an equation: 1 solution

ex: x=3+2y

Since both sides of the equal sign are 4, we have infinitely many solutions.

Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

Answer:

The number that both a rational number and a whole number is 22

Step-by-step explanation:

The whole numbers are the non-negative integers

The integers are rational numbers with denominators 1

The rational numbers are the numbers that can be written in the form of [tex]\frac{a}{b}[/tex] ,

b ≠ 0

Let us study the numbers in the figure:

The set of whole numbers ⊂ the set of integers ⊂ the set of rational numbers

∵ 22 ∈ the set of whole numbers

∴ 22 is a whole number

∴ 22 is a whole number and an integer

∴ 22 is a whole number, an integer, and a rational number

The set of integers ⊂ the set of rational

∵ -88 and -191 ∈ the set of integers

∴ -88 and -191 are integers

∴ -88 and -191 are integers and rational numbers

∵ -10.1 ∈ The set of rational numbers

∴ -10.1 is a rational number

Let us answer the question

→ We need to find a number that is a rational number and a whole number,

   which means it must ∈ to the set of the whole numbers

∵ We only have one number ∈ the set of whole numbers, it is 22

∴ The number that both a rational number and a whole number is 22

Answer:

Triangle =  1 1/2

Square = 10

Step-by-step explanation:

Given:

Triangle + Triangle + Square + Square = 23

Square - Triangle = 4 1/2

10 + 10 + 1 1/2 + 1 1/2 = 23

Hence, Square = 10 and Triangle = 1 1/2

Step-by-step explanation:

Train 1 speed be 'u'

Train 2 speed be 'v'

And v=2u

Speed=distance/time

Trains going in opposite directions

Relative speed= v-u (as train 1 I slower than train 2)

v-u=600/4

2u-u=150

u=150miles/hour

v=300miles/hour

The histogram showing the number of events with the events cost is

misleading because;

Please find attached a possible diagram of the histogram in the question

created with MS Excel;

The data in the histogram is presented as follows;

[tex]\begin{array}{|c|c|c}Event \ Cost&Number \ of \ Events\\1000- 1499&2\\1500-1999&4\\2000-2499&3\\3000-3499&1\end{array}\right][/tex]

From the above table, we have that the class with event cost of 2000 to

2499 is left out, therefore, the data is more clustered.

Answer: Tetsurō Kuroo here!

Step-by-step explanation:

Yes that is true.

Step-by-step explanation:

Ok, so first...

a) if x is positive, it will remain x, so *x<7*

b) if x+3 is positive, it will be x+3<9 but you have to simplify it so you subtract 3 on both sides and get *x<6*

c) if y-8 is positive, it will stay like that, and you then add 8 on both sides to get *y>19*

g) if 3x-1 is positive, it will be 3x-1 greater than or equal to 18. add 1 on both sides and *3x > or = to 18*

4y+3 < or = 13. subtract 3 on both sides and you get *4y < or = 13*

x = 6√6

Step-by-step explanation:

27/x = x/8

x² = 27 × 8

x = √(27 × 8)

x = √(9 × 4 × 6)

x = 3 × 2 × √6

x = 6√6

Answer:

The geometric mean of 27 and 8 is [tex]6\sqrt{6}[/tex] or about 14.697

Step-by-step explanation:

The geometric mean is [tex]( \prod_{i=1}^{n} x_{i})^{\frac{1}{n}}=\sqrt[n]{x_1x_2 \cdot\: \cdot \:\cdot x_n}[/tex] where [tex]n[/tex] is the number of values and [tex]x_i[/tex] are the values to average. Thus, your geometric mean is [tex]\sqrt{27*8}=\sqrt{216}=6\sqrt{6}\approx14.697[/tex]

Answer:

x = 25

Step-by-step explanation:

The sum of the three interior angles of a triangle is always 180°.

4x + 2x + 30 = 180

6x + 30 = 180

6x = 150

x = 25

Answer:

sum of the interior angles of a triangle =180

2× + 4× + 30=180

6× + 30= 180

6× + 30 = 180

6× = 180-30

6× =150

6×/6=150/6

×= 25

Answer:

-4h < - 14

We solve for h by applying the inverse operations;

The inverse operation of multiplication is division, so we divide by -4 on both sides;

/-4      /-4

h < 3.5, it could be 3.4, 3.3, 3.2 3.123, 2.4, 2.576, there are tons of numbers below 3.5.

So anything below 3.5 would best be suitable for the equation.
