Find the value of h (b) = 3b2 - 2b + 1 when b = -3. ...

Find g (2w) when g (x) = x2 - 2x + 1.

Step-by-step explanation:

The coordinates of the points lying on the graph of y = - (3/4)x + 1 represents each value.

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

We have the following equation of line -

g(x) = 1 - (3/4)x

We can write it as -

y = 1 - (3/4)x

y = - (3/4)x + 1

Plot the graph of the function. The coordinates of the points lying on the graph represents each value.

Therefore, the coordinates of the points lying on the graph of y = - (3/4)x + 1 represents each value.

Answer:

My work got 192,150

Step-by-step explanation:

I started off by doing 100/29.3 which would get 3.41296928328

I would then multiply that number by 56300 to get a rough number of 192150.170649

BUT!!! there can not be .170649 of a person so i got 192,150.

P.S. sorry if the answer is incorrect I am not too smart right now. Hope this helps

Answer:

52 + 13x

Step-by-step explanation:

To distribute something means to divide / share a part of something. The distributive property works similarly. The distributive property states that multiplying the total sum of two variables by a number is the same as the total sum of each product of individual variables and the number.

For example: a(b+c) = ab + ac

Therefore, in order to distribute the 13 into the terms inside the parentheses, you follow the distributive property and multiply each individual variable in the parentheses by 13 and add all the resulting products.

13(4 + x) = (13*4) + (13*x) = 52 + 13x

Step-by-step explanation:

hope thai HELPS!

Answer: C

Step-by-step explanation:

The equation is in y=mx+b format. The y is the final amount that you will have to pay. The m in this case is the amount of money that you are paying for each individual month (which is $34.99). The x in this case is the number of months you are paying for (which is 1). And b is the starting fee that you have to pay in order to get a membership in the first place (but will not have to pay after the first month). Thus, seeing as there is 1 month's worth of payment and a starting fee tagged on, y would equal the average total cost for the first month of a gym membership.

Answer:

24

Step-by-step explanation:

first subtract 0.1x from both sides and add 5 to both sides to get your variables together and constants together.

0.6x-0.1x=7+5

now simplify both sides

0.5x=12

Divide both sides by 0.5 to get the variable by itself

x=12/0.5

simplify

x=24

Perimeter of rectangle = 2(l+w)

So, 54cm = 2(l+9cm)

=> 54cm = 2l + 18cm

=> 54cm - 18cm = 2l

=> 36cm = 2l

=> 36cm/2 = l

=> 18cm = l

Answer:

The answer is B.

Step-by-step explanation:

Answer: first Option

Work: So, Slope Intercept form is y=mx+b, so, we need to get the 13x Away from there. So, we subtract 13x from there, and we get -11y = 13x - 12. To get it to y, we divide 13x - 12 by -11. So the new equation is y = -13/11x + 12/11

Answer:

140 grams

Step-by-step explanation

Let n be the amount of distilled water needed. Then:

.7(56)=.2(56+n)

39.2=11.2+.2n

.2n=28

n=140 gram distilled water

The amount of distilled water should the pharmacist add to make a 20 percent solution is 140 g.

Given-

Total weight of the solution is 56 grams.

The percentage of antiseptic in the given solution is 70 percent.

The percentage of the water in the given solution is total solution minus the percentage of antiseptic solution. As we know that the total solution is represent as 100 percent. Thus the percentage of the water in the given solution,

[tex]=100-70=30[/tex]

Therefore the percentage of the water in the given solution.

In the new solution the percentage of antiseptic is 20 percent. For this solution  The percentage of the water,

[tex]=100-20=80[/tex]

Now the sum of the distilled water and the given solution (30 percent water solution) is equal to the sum of the distilled water and the 20 percent solution (80 percent water solution).Let [tex]x[/tex] be the quantity of the distilled water, we get,

[tex]x+\dfrac{30}{100} \times 56=\dfrac{80}{100} (56+x)[/tex]

[tex]x+0.3 \times 56=0.8(56+x)[/tex]

[tex]x+16.8=44.8+0.8x[/tex]

[tex]x-0.8x=44.8-16.8[/tex]

[tex]0.2x=28[/tex]

[tex]x=\dfrac{28}{0.2}[/tex]

[tex]x=140[/tex]

Hence, the amount of distilled water should the pharmaceutics add to make a 20 percent solution is 140 g.

Step-by-step explanation:

First add 18 and 24 which gives you 42.

Then divide that by 6

That gives you 7, which means the total inside the parentheses must equal to 7.

Answer:

About 2970 princesses

Step-by-step explanation:

This is calculated as:

For 1 student:

1 minute = 2 princesses

55 minutes = x princesses

x = 55 × 2 princesses

x = 110 princesses.

Hence: 1 student can make 110 princesses in 55 minutes.

The amount of princesses all the students make in 55 minutes is calculated as:

1 student = 110 princesses

27 students = x

x = 27 × 110 princesses

x = 2970 princesses

The amount of princesses all the students make in 55 minutes is about 2970 princesses.

Explanation:

Check out the attached image below. I've marked up your diagram such that I've canceled the proper units. Any cancelation happens when we divide one unit over another. Take note of the color coding.

The miles units cancel out (in red), the hours units cancel (blue), and the feet units cancel (green). We're left with inches over minutes, which leads to the final units being "inches per minute".

Answer:

The inequality for the graph is y > -2x + 7 ⇒ A

Step-by-step explanation:

At first let us find the equation of the line, then write the inequality

∵ The form of the equation of the line is y = m x + b, where m is the slope

   and b is the y-intercept (value x at y = 0)

∵ m = [tex]\frac{y2-y1}{x2-x1}[/tex] , (x1, y1) and (x2, y2) are 2 points on the line

∵ The line passes through points (3, 1) and (0, 7)

∴ x1 = 3, y1 = 1 and x2 = 0, y2 = 7

→ Substitute them in the rule of the slope above

∵ m = [tex]\frac{7-1}{0-3}[/tex] = [tex]\frac{6}{-3}[/tex] = -2

∴ m = -2

→ Substitute it in the form of the equation

∴ y = -2x + b

∵ b is the value of y at x = 0

∵ y = 7 at x = 0

∴ b = 7

→ Substitute it in the equation

∴ y = -2x + 7

→ Now let us write the inequality

∵ The line is a dashed line and the shading is above the line

∴ The sign of inequality is >

→ Change "=" in the equation of the line by ">"

∴ The inequality is y > -2x + 7
