Solve the system by substitution.
y = -2x+ 28
y = 5x

Answer:

Problem 1: No

Problem 2: Yes

Step-by-step explanation:

Problem 1:

{(-2, 1), (-2, 3), (0, -3), (1, 4), (3, 1)}

This relation is not a function because there are two y-values, 1 and 3, related to one x-value, -2.

Thus, for a relation to be a function, every x-value must be related to exactly 1 y-value.

Problem 2:

{(0, 2), (3, 4), (-3, -2), (2, 4)}

In this relation, each x-value (domain) has exactly one y-value (range) that it is related to. Therefore, this is a function.

Answer:

Write the relation as a set of ordered pairs.

Step-by-step explanation:

A relation. An arrow goes from negative 2 to 4, 0 to 6, 2 to 8.

a.

ordered pairs: {(4, –2), (0, 6), (2, 8)}

b.

ordered pairs: {(–2, 4), (0, 6), (2, 8)}

c.

ordered pairs: {(4, –2), (0, 6), (8, 2)}

d.

ordered pairs: {(–2, 4), (6, 0), (8, 2)}

Answer:

There are no solutions

Step-by-step explanation:

No intersections or points that apply for the equations.

Any intersection between both lines is a solution. As these lines are parallel they have no solution. If they met at any point, 90 degree or not, there is  solution, the solution will be a point. If they are on the same line, hitting all the same points, the solutions are infinite.

The statements which describe the transformation on the left are:

A transformation refers to the movement of a point from its original position to a new location. Hence, when an object is transformed, all of its points would also be transformed.

Based on the image of these geometric figures (see attachment), we can infer and logically deduce that the following statements describe the transformation on the left:

Answer: 2g - 32

Step-by-step explanation:

-2 (3g - 8g + 8) - 9g - 2 (3g - 8g + 8) - 9g

First step is to use the distributive property to distribute 2.

The expression is now:

-6g + 16g - 16 - 9g - 6g + 16g - 16 - 9g

Now you put the like terms together..

-6g + 16g - 9g - 6g + 16g - 9g -16 - 16

All that is left to do is combine them!

(-6g + 16g - 9g - 6g + 16g - 9g) + (-16 - 16)

2g + (-32)

2g - 32

Hence , correct option is Option B i.e. Mel did pass the class.

The statement says that Mel scored C+ is Chemistry.

We will approach our answer logically by examining each option.

Option A says Mel does not like chemistry. This Cannot be true because maybe Mel likes chemistry but he just has scored less or maybe this C+ is an achievement for Mel.

Option B says that Mel did pass the class. This is possible because a student is considered as not qualified if he/she scores D or below, but Mel has scored C+ which is above the qualifying criteria.

Option C says that Mel did not achieve a passing grade for the class which is false because C+ is a passing grade scored by Mel.

Option D is Mel took math this semester which doesn't makes any sense.

hence, Option B is correct.

The quotient of [tex]20\sqrt{z^{6} }[/tex] ÷ [tex]\sqrt{16z^{7} }[/tex] in simplest radical form is  [tex]\frac{5\sqrt{z} }{z}[/tex].

Expressing in simplest radical form just means simplifying a radical so that there are no more square roots, cube roots, 4th roots, etc left to find. It also means removing any radicals in the denominator of a fraction.

Given

[tex]20\sqrt{z^{6} }[/tex] ÷ [tex]\sqrt{16z^{7} }[/tex]

Rewrite as fraction: [tex]\frac{20\sqrt{z^{6} } }{\sqrt{16z^{7} } }[/tex]

Factor and rewrite the radicand in exponential form: [tex]\frac{20\sqrt{z^{6} } }{\sqrt{4^{2}. z^{6} .z} }[/tex]

Rewrite the expression using [tex]\sqrt[n]{ab} =\sqrt[n]{a} \sqrt[n]{b}[/tex] :

= [tex]\frac{20\sqrt{z^{6} } }{\sqrt{4^{2} .\sqrt{z^{6}.\sqrt{z} } } }[/tex]

Simply the radical expression, we get:

= [tex]\frac{20z^{3} }{4z^{3}\sqrt{z} }[/tex]

Reduce fraction to the lowest term by canceling the greater common factor, we get

= [tex]\frac{5}{\sqrt{z} }[/tex]

Rationalize the denominator

= [tex]\frac{5\sqrt{z} }{\sqrt{z} .\sqrt{z} }[/tex]

= [tex]\frac{5\sqrt{z} }{z}[/tex]

Hence, the quotient of [tex]20\sqrt{z^{6} }[/tex] ÷ [tex]\sqrt{16z^{7} }[/tex] in simplest radical form is  [tex]\frac{5\sqrt{z} }{z}[/tex].

Answer: X-intercept is (2,0)

Y-intercept is (0,-2)

Step-by-step explanation:

Answer:

X-intercept is (2,0)

Y-intercept is (0,-2)

Step-by-step explanation:

The x intercept is the point at which the line hits the x-axis

in this picture, you can see that the given line hit the x-axis at (2,0)

The y intercept is the point at which the line hits the y-axis

so in this case you can see the the line hits the y-axis at (0,-2)

Bonus: if a line is horizontal it will not have an x intercept, and if a line is vertical, it will not have ay intercept

Answer:

6.5=30, 5.3.5.2=150

It is a geometric series.

30, 150,......

a1=30

common ratio

r= 150/30= 5

an=ar^(n-1)

The next term in the sequence is obtained by subtracting 4 from the previous term:

13 = 17 - 4

9 = 13 - 4

5 = 9 - 4

and so on.

Recursively, we can describe the n-th term in the sequence (denoted a(n)) as a function of the (n - 1)-th term:

a(n) = a(n - 1) - 4

starting with a(1) = 17. So we have, for instance,

a(2) = a(1) - 4 = 17 - 4 = 13

We want to find an explicit formula for a(n), meaning we want a way to determine the n-th term only as a function of n, and not any other known term in the sequence. We can iteratively apply the recursive rule above:

a(n) = a(n - 1) - 4

a(n - 1) = a(n - 2) - 4

→   a(n) = (a(n - 2) - 4) - 4 = a(n - 2) - 2×4

a(n - 2) = a(n - 3) - 4

→   a(n) = (a(n - 3) - 4) - 2×4 = a(n - 3) - 3×4

a(n - 3) = a(n - 4) - 4

→   a(n) = (a(n - 4) - 4) - 3×4 = a(n - 4) - 4×4

and so on, down to

a(n) = a(1) - (n - 1)×4

The first term is a(1) = 17, so

a(n) = 17 - 4 (n - 1) = 21 - 4n
