Select if each equation has ONE SOLUTION, INFINITE SOLUTIONS, NO SOLUTIONS

2(3x-7) = 6x-14
-5x+12 = -5(x-2)
4(x-2) = 3x+1

Answer:(a) x - 0.7 = 1.5

Step-by-step explanation:

Determine whether each of the following is a solution of x − 0.7 = 1.5: (a) x = 1 (b) x = −0.8 (c) x = 2. Step 1. Substitute the number for the variable in the equation.

Step 2. Simplify the expressions on both sides of the equation.

Step 3. Determine whether the resulting equation is true.

If so, the number is a solution.

If not, the number is not a solution.

There are 48 minnows in the aquarium and there are 18 clownfish in aquarium

Given that in an aquarium ratio of minnows and clown fish is 8:3 and the ratio of clownfish and goldfish are in ratio 6:11 and there are 33 gold fishes in the aquarium.

⇒[tex]\frac{6}{11} =\frac{x}{33}[/tex] ( Here x is the number of clownfish)

⇒x=6×3

⇒x=18

Therefore, The number of clownfish in the aquarium is 18

Now,[tex]\frac{8}{3} =\frac{y}{18}[/tex](Here, y is the number of minnows in an aquarium)

⇒y=8×6

⇒y=48

Therefore, The number of minnows in the aquarium is 48

Therefore,The number of minnows in the aquarium is 48 and The number of clownfish in the aquarium is 18

Answer:

90 ft

Step-by-step explanation:

first you find the area of the 10 by 3 triangle, since on the other side it,s the same, all we need to do is find one of each triangle then mulitply it by 2 to get the area. then find the area of the 20 by 3 triangle. once you do that you will get 45, then you multiply it by 2 because it is the exact same on the other sides. then when you do that you get 90 ft. I hope this helps you! peace out.

How to Make Money Without a Job:

The number of physics textbook is 174 and maths textbook is 58.

Let the number of maths textbook = x

The number of physics textbook = 3x

Therefore, the expression will be:

3x + x = 232

4x = 232

Divide

x = 232/4

x = 58

Physics textbook = 3x = 3 × 58 = 174

Therefore, the number of physics textbook is 174 and maths textbook is 58.

The vertex and range of the given function is y = x + 1 + 3 is (0, 4); - (0, 4); 3 ≤ y ≤ ∞.

The Domain of a function is the set of all possible values that a function satisfies.

The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we put an x value in.

Now the given function is,

y = (x + 1) + 3

or, y = x + 4

Now to find the y coordinate of vertex,

put x = 0 in the given function is,

Thus, we get

y = 4

So, the vertex of the given function is

y = x + 1 + 3 is (0, 4); - (0, 4).

Now for range,Put (x + 1) = 0 in the given function

Thus we get,

y ≤  ∞

and y ≥ 3

Thus the range of the given function will be,3 ≤ y ≤ ∞

Thus, the vertex and range of the given function is y = x + 1 + 3 is (0, 4); - (0, 4); 3 ≤ y ≤ ∞

Answer: it is 4 over 8 and undefined as the direct inverse of mathematical theory of bill nye the science guy *music starts playing*

Step-by-step explanation:

The formula for density is d = m/v.

d = density

m = mass

v = volume

The volume of the rock is 15 cubic centimeters.

The mass of the rock is 45 grams.

Now just plug these into the formula and solve.

d = 45/15.

45/15 = 3.

The density of the rock is 3 grams per cubic centimeters.

Mass of the rock = 45 g

Volume of the rock = 15 cubic cm

Density = Mass / Volume

By putting the respected values, we get

Density = 45 g / 15 cubic cm = 3 gram/cubic centimeter

Density of the rock is 3 gram/cubic centimeter.

Answer:

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

Let the number of $15 tickets is x and numbers of $20 tickets is y.

Set the system according to given information:

Solve by elimination, multiply the first equation by 20 and subtract the second equation:

Find y:

The value of x from the equation is  2√2

Linear equations are equations with one or two variables.

It is also important to note that the highest power of variable is 1

Given the equation;

yx² = 8y

Let's make 'x' the subject of the equation

Divide both sides by y, we have;

yx²/y = 8y/ y

x² = 8

Take the square root of both sides

(√x²) = √8

The square root takes the square, we have

x = √8

x = √4 × 2

x = 2√2

Thus, the value of x from the equation is  2√2

Step-by-step explanation:

Since the question is or, we only need to answer one. For q, there is of course no answer that will not end the division in decimals. So lets move on to p. The only number that is greater than 20 is 99. Also, 99 is divisible by 5, it will just end in decimals. So the answer is 99.

Answer:

x = 4

Step-by-step explanation:

We are asked to find the value of x when [tex] \frac{7}{2} [/tex].

Note that [tex] f(x) [/tex] is also y.

What this means is, what is the value of x when y = 7/2 = 3.5.

On the graph given, trace where y = 3.5. check the x-value that corresponds with it on the point on the line.

Thus, at y = 3.5, x = 4.

Therefore,

x = 4, when [tex] \frac{7}{2} [/tex].
