Answer:

A(1,-5) C (2,-2)

Step-by-step explanation:

Whenever you are reflecting across the x-axis, just visualize the same thing upwards or downwards. In this case, we will have to go downwards. To reflect from the x-axis, A (which‘s ordered pair is (1,5)) would become (1,-5). Same with C (which’s ordered pair is (2,2))) would become (2,-2).

First, you should multiply what's inside the parenthesis.

( 6 × 3 )x + 4 + 2x

18x + 4 + 2x

Then you add the numbers that include a variable.

18x + 4 + 2x

20x + 4

The equation can not be simplified any farther, so this is our final answer.

20x + 4

Which graph shows the solution to the following system?

artcher [175]

we have

$y=\frac{1}{4} x-2$ -----> equation $1$

$y=\frac{7}{4} x+4$ -----> equation $2$

Resolve the system

we know that

the solution of the system is the intersection of both graphs

Multiply by $-1$ equation $1$

$-y=-\frac{1}{4} x+2$

Adds equation $1$ and equation $2$

$-y=-\frac{1}{4} x+2$

$y=\frac{7}{4} x+4\\ ------$

$0=\frac{6}{4}x +6\\ \\ 0=6x+24\\ 6x=-24\\ x=-4$

find the value of y

$y=\frac{7}{4}*(-4)+4\\ \\ y=-7+4\\ y=-3$

the solution is the point $(-4,-3)$

therefore

the answer is

The solution is the graph in the attached figure

May someone help me please?

Since we know that g(x) is between h(x) and f(x) we can use the same formula format.
If g(x) = a * b^x
a = 160 most likely
b^x would be between 4/5 and 1/5
Look at desmos example below where the third is 3/5^x and lies directly between the first 2

How many solutions can a quadratic equation have and why does it vary? How would the corresponding graphs look like?

tino4ka555 [31]

Hello from MrBillDoesMath!

Answer:

0, 1, or 2

Discussion:

Examples:

1) x^2 + 9 = 0 has 0 solutions over the real numbers

2) x^2 + 9 = 0 has 2 solutions over the complex number ( 3i, -3i)

3) the quadratic (x-3)^2 = 0 has a single solution, x = 3, of multiplicity two. (which some regard as two solutions).

The bottom line is the number of roots is given by the quadratic solution

( -b +\- sqrt( b^2 - 4ac) ) /2a

In particular if the discriminant (b^2 -4ac) = 0, the quadratic has one solution. If the discriminant is >0 there are two (real) solutions, and if the discriminant is <0 there are 2 imaginary (complex) solutions.

Thank you,

MrB
