Answer:

b) (3, 18)

Step-by-step explanation:

f(x) = g(x) at the point where the two lines <u>intersect</u>.

From inspection of the graph, we can see that the x-value of the point of intersection is between 0 and 10. Therefore, from the options given, it must be x = 3 (since 12 > 10 and 18 > 10).

From inspection of the graph, we can see that the y-value of the point of intersection is between 10 and 20, but it's nearest to 20 than it is 10. Therefore, from the options given, it must be y = 18.

Therefore, the approximate ordered pair is (3, 18)

The approximate ordered pair is the coordinate where both functions graph intercect

That's can be found only by observing graph.

As we observe we find that

The coordinate at where f(x)=g(x) is (3,18)

It means that

at this the values of both the functions are equal

i.e

f(3)=g(3)=18

Can someone fr help me with this like right now i’ll appreciate it sm

rjkz [21]

Step-by-step explanation:

Since

$\frac{108}{72} = \frac{3}{2}$

$\frac{72}{48} = \frac{3}{2}$

$\frac{48}{32} = \frac{3}{2}$

The function has a constant factor so we have a exponential function.

The equation of a exponential function is

$y = a(b) {}^{x}$

Where a is the initial value and b is the growth factor

The growth factor is 3/2,

The initial value in 32

$y = 32 ( \frac{3}{2} ) {}^{x}$

Plug in 4 for x.

You will get 162

Plug in 5 for x you will get

243.

Answer:

x = 5

Step-by-step explanation:

Given

8 = $\frac{5x-1}{3}$

Multiply both sides by 3 to clear the fraction

24 = 5x - 1 ( add 1 to both sides )

25 = 5x ( divide both sides by 5 )

x = 5

effie ate 4 peaches. this represents 50% of the bag of peaches. how many peaches were originally in the bag?

Marat540 [252]

8 peaches. 8 peaches because if effie ate 4 peaches, or half of the bag, you would have to multiply 4 by 2 to get the answer of 8 peaches. mark brainliest please!

Answer in order:

False

True

False

True

Step-by-step explanation:

All of the solutions to the equation $3x^2 - 12 = 0$ are x = 12 and x = -12

Solve:

Common factor - $3(x^2-4)=0$

Divide both sides

$x^2-4=0$

Use the quadratic formula

$x=\sqrt{4,x}=\sqrt{-4$

x = 2, x = -2

Thus, This is false..

-------------------------------------------------------------------------------------------------------------

There are two unique solutions to the equations (x-3)^2 = 16

one variable in matrix = one possible value.

Therefore, x = 7, x = -1

Hence this is True

-------------------------------------------------------------------------------------------------------------

The solutions for the equation 2(x-3)^2-18 = 0 are x = 6 and x = 0

$2x^3-18x^2+54x-72=0$

$x=5.080084$

Hence this is false

-------------------------------------------------------------------------------------------------------------

The solutions for the equation 2(x-5)^2-8=0 are x = 7 and x = -7

Add both sides by 8

2(x-5)^2-8+8=0+8

2(x-5)^2=8

(x-5)^2=4

x = 7, x = 3

Hence, this is false

-------------------------------------------------------------------------------------------------------------

The solutions for the equation (x + 3)^2-25 = -8 are x = 2 and x = -8

$(x+3)^2=17$

$x=\sqrt{17-3,}=-\sqrt{17}-3$

Hence this is false.

-------------------------------------------------------------------------------------------------------------

The solutions for the equation 2(2x-1)^2=18 are x = 5 and x = -4

$(2x-1)^2=9$

x=2, x = -1

Hence this is false.

-------------------------------------------------------------------------------------------------------------

The only solution for equation (2x-1)^2-49=0 is x = 4

$(2x-1)^2=49$

x = 4, x = -3

Hence, this is false

-------------------------------------------------------------------------------------------------------------

The solutions for the equation 3(x+2)^2 - 3 = 0 are x = -3 and x = -1

$3(x+2)^2=3$

$(x+2)^2=1$

x = -1, x = -3

Hence, this is true

-------------------------------------------------------------------------------------------------------------

The solutions for the equation 5x^2 - 180 = 0 are x = 6 and x = -6

Add 180 to both sides

$5x^2-180+180=0+180$

$5x^2 = 180$

$x^2 = 36$

$x=\sqrt{36},x=-\sqrt{36}$

x = 6, x = -6

Hence, this is true.
