Answer:

y=1/3x-3

m1=1/3

from,m1m2=-1

1/3m2=-1

m2=-3

again, from

m=(y-y1)/(x-x1)

-3=(y-2)/(x-3)

y-2=-3(x-3)

y-2=-3x+9

y=-3x+9+2

y=-3x+11

Answer:

x=112

Step-by-step explanation:

[tex]\frac{x}{7} =16[/tex]

x=16*7

x=112

Answer: x = 112

Step-by-step explanation: To solve this equation for x,

I would first change x ÷ 7 to x/7 to make it easier to visualize.

So we have [tex]\frac{x}{7} = 16[/tex].

Since x is being divided by 7, we multiply both sides by 7.

On the left, hat gives us x and on the right, 16 x 7 is 112.

So we have x = 112.

Answer:

14%

Step-by-step explanation:

42 ÷ 300 = 0.14 = 14%

or

subtract 42 from 300 which gives you 258

258 is 86% of 300

86-100 is 14 so 14%

Answer:

x = 11.4

Step-by-step explanation:

14.12 = [tex]\frac{1}{2}[/tex] ( 3.6x - 12.8 )

Rewrite so that the equation is entirely in decimals;

14.12 = 0.5( 3.6x - 12.8 )

Distribute;

14.12 = 1.8x - 6.4

Inverse operations;

14.12 = 1.8x - 6.4

+6.4            +6.4

20.52 = 1.8x

/1.8        /1.8

11.4 = x

Answer:

11.4

Step-by-step explanation:

14.12= 1/2(3.6x-12.8)

14.12=1.8x-6.4

20.52=1.8x

x=11.4

Hope that helps :)

Answer:

The simplest form of 42/18 is 7/3 or 2 1/3

Step-by-step explanation:

Answer:

7/3 or 2 and 1/3

Step-by-step explanation:

So first you have to find what is GCF of 42 and 18, which is 6 so divide 42 and 18 by 6 and you get 7/3 which is your simplified fraction but you can make this into a mixed number which would be 2 and 1/3

Answer:

[tex]( - 2) ^{4} \times ( - 3) ^{7} \\ = 16 \times 27 \\ = positive[/tex]

Answer:

6 cells

Step-by-step explanation:

Cell A = 1 hour to complete cycle and produce 2 cells

Number of cycles completed on 6 hours = 6 cycles

Number of cell produced = 2 * number of completed cycles = 2 * 6 = 12 cells

Cell B = 2 hours to complete a cycle ; 2 cells produced per cycle

Number of cells produced after 6 hours :

Number of cycles in 6 hours = 6/2 = 3 cycles

Number of cells produced = 3 * 2 = 6 cells

Difference in cells produced : (12 - 6) = 6 cells

Answer:

I would have to say D

Step-by-step explanation:

because it is a complete function

The function [tex]f(x)=100^{x-5}-1[/tex] has a x-intercept

For an exponential function to have a x-intercept, the function must cross the x-axis

To determine the function, we simply plot them on a graph.

From the graph (see attachment), we can see that the graph of the function [tex]f(x)=100^{x-5}-1[/tex] crosses the x-axis.

This means that the function [tex]f(x)=100^{x-5}-1[/tex] has a x-intercept

Answer:

The answer is 4.6.

Step-by-step explanation:

If you look at the graph closely, you would see that the intersection is very close to 4, so the answer is 4.6.

Step-by-step explanation:

We need to use the binomial theorem/Pascal's triangle here.

(a+b)^5 = (5 choose 0)a^5 + (5 choose 1)a^4*b + (5 choose 2)a^3*b^2 + (5 choose 3)a^2*b^3 + (5 choose 4)a*b^4 + (5 choose 5)b^5.

5 choose 0 = 1

5 choose 1 = 5

5 choose 2 = 10

5 choose 3 = 10

5 choose 4 = 5

5 choose 5 = 1

And 1, 5, 10, 10, 5, 1, is the (5+1) = 6th row of pascal's triangle.

Therefore we get

g^5 + 5g^4*2 + 10g^3*2^2 + 10g^2*2^3 + 5g*2^4 + 2^5

which is

g^4 + 10g^4 + 40g^3 + 80g^2 + 80g + 32

Or, you could do the slow way, by just doing (g+2)(g+2)(g+2)(g+2)(g+2)

Answer:

D) V= 1/6 bh

Step-by-step explanation:

The expression that provides the volume of the pyramid is as follows;

As mentioned in the question

It is given that the pyramid put inside a prism

Also the pyramid contains the similar base area but the height is half of the prism

so the base area of the pyramid is b

And, the Height of the pyramid = h ÷ 2

Now as we know that  

The volume of the pyramid is

V = 1 ÷3 × base ares × height

= 1 ÷ 3 × b × h ÷ 2

V = 1 ÷ 6 bh

So, the volume is 1 ÷6 bh cube unit.

Answer:

V = 1/6 BH

Step-by-step explanation:

the volume of a pyramid is 1/3 BH , since the pyramid is only half the height of the prism you'll have to multiply 1/3 x 2 = 1/6

Step-by-step explanation:

Answer:

(2.5, 5.5)

Step-by-step explanation:

The formula for calculating the midpoint of two coordinates is expressed as;

M(X, Y) = {(x1+x2/2, y1+y2/2)}

X = x1+x2/2

Y = y1+y2/2

Given the coordinates (7, 8) and (-2, 3)

X = 7-2/2

X = 5/2

X = 2.5

Y = y1 + y2/2

Y = 8+3/2

Y = 11/2

Y = 5.5

Hence the midpoint M of the coordinates is (2.5, 5.5)
