explain how to solve 3b=48. Give the solution in you explanation
Answers
Answer:
b=16
Step-by-step explanation:
1) Divide 3 on both sides.
2) 3 divided by 3 and 48 divided 3.
3) Now you're left with 16, so the value of b is 16.
Answer:
1) Divide both sides by 3
2) b=16
Step-by-step explanation:
To solve the equation, we want to find out what b is. In order to do this, we have to get b by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.
3b=48
3 and b are being multiplied (3b=3*b). The opposite of multiplication is division. Therefore, divide both sides by 3.
3b/3=48/3
The 3s on the left will cancel, and we are left with:
b=48/3
b=16

Rewrite the numbers
1,20,4,3,4,1,2,5,1,4,1,2,7,1,2,1,2,11,3,2,2,2,4,5,7
1.
a: I can't draw a line plot, but I can tell you some tips.
Set the x as the different numbers that appear in the set
Set the y as the frequency of each number.
b: 2 fish has the highest frequency.
c: Add the terms. 97 is the total fish been bought
d: The outlier is 20 bought fish
2.
a: When making the stem and leaf plot, do it in this format
1| 7,4,3,5,8,4
and so on.
b: the heaviest puppy is 25 and the lightest is 13
so the range is 12
c: 4 puppies weighed at least 20 pounds
3. There are no following values, but for this I would make a box and whisker plot.
4. There is no histogram but it should be relatively easy if you know which aspect of the graph to use.
a: Find the frequency of each bar and add them.
b: the largest number of boxes is the interval that is the largest
c: Use the graph to find it
d: I can't do this without the graph.

y=x^{2} +2x-8 determine the axis of symmetry, the vertex point and find the roots by factoring
Answers
Answer:
We have axis of symmetry in [tex]x=-1[/tex]
The vertex point is [tex](-1, -9)[/tex]
The roots by factoring are
[tex]x=-4[/tex]
[tex]x=2[/tex]
Step-by-step explanation:
We have the function:
[tex]f(x)=x^2+2x-8[/tex]
Factoring the quadratic equation:
[tex]y=(x+4)(x-2)[/tex]
When [tex]y=0[/tex]
[tex]0=(x+4)(x-2)[/tex]
[tex]x=-4[/tex]
[tex]x=2[/tex]
The vertex point is [tex](h, k)[/tex]
From the equation, we have [tex]a=1,\:b=2 \text{ and }\:c=-8[/tex]
[tex]$h=-\frac{b}{2a}$[/tex]
[tex]$h=-\frac{2}{2\cdot \:1}$[/tex]
[tex]h=-1[/tex]
We also got the axis of symmetry
In order to find [tex]k[/tex] just use the [tex]$h=x_{vetex}$[/tex]:
[tex]k=(-1)^2+2(-1)-8\\k=1-2-8\\k=-9[/tex]
Once [tex]a>0[/tex], we have the minimum at [tex](-1, -9)[/tex]
Answer:
x = -1 axis of symmetry
(-1,-9) vertex
x = -4 x=2 are the roots
Step-by-step explanation:
y = x^2 + 2x - 8
The axis of symmetry is
h = -b/2a
h = -2/ (2*1) = -2/2 =-1
x = -1
The x coordinate of the vertex is at the axis of symmetry
To find the y value substitute into the function
y = (-1)^2 +2(-1) -8
y = 1-2-8
y = -9
The vertex is at ( -1,-9)
Factor
What 2 number multiply to -8 and add to 2
4*-2 = -8
4+-2 = 2
y = ( x+4) (x-2)
Using the zero product property to find the roots
0 = ( x+4) (x-2)
x+4 =0 x-2 =0
x = -4 x=2 are the roots

A concrete pillar has the shape of a cylinder. It has a diameter of 8 meters and a height of 9 meters. If concrete costs $87 per cubic meter, how much did the concrete cost for the pillar?
Answers
Answer:
Cost, C = $28410.72
Step-by-step explanation:
We have, a concrete pillar has the shape of a cylinder.
Diameter of pillar is 8 m and ts height is 9 m
If concrete costs $87 per cubic meter, it is required to find the concrete cost for the pillar. For this lets find the area of cylindrical shape. So,
[tex]A=2\pi rh+2\pi r^2\\\\A=2\times 3.14\times 4\times 9+2\times 3.14\times 4^2\\\\A=326.56\ m^2[/tex]
The cost of pillar at the rate of $87 per cubic meter will be :
[tex]C=326.56\times 87\\\\C=\$28410.72[/tex]

Question 7: Distributive
You multiple the outside element by each element inside the parenthesis
Question 5: 1.2x + 12.3y
2.4(3x + 2y) - 1.5(4x - 5y) = 7.2x + 4.8y - 6x + 7.5y = 1.2x + 12.3y
Question 3: 1 (3/5)x - (3/10)y
(2/5)(4x - 3y/4) = (8/5)x - 6y/20 = 1 (3/5)x - (3/10)y
Question 2: 1 (7/15)x
(4/5)x + (2/3)x = (12/15)x + (10/15)x = (22/15)x = 1 (7/15)x
Question 1: -2x + 3y
(3/4)(8x-4y) - (2/3)(12x - 9y) = 6x - 3y - 8x + 6y = -2x + 3y
Hope this helps!
Answer:
Question 7: Distributive
Question 5: [tex]1.2x+12.3y[/tex]
Question 3: [tex]$1\frac{3}{5}x -\frac{3}{10}y $[/tex]
Question 2: [tex]$1\frac{7}{15} x$[/tex]
Question 1: [tex]-2x+3y[/tex]
Step-by-step solution:
Question 7
[tex]4(x-5)=4x-20[/tex]
Distributive property, [tex]a(b + c) = ab + ac[/tex]. It says that multiplying the sum of two or more addends (numbers or terms added together) by a number (a) will give the same result as multiplying each addend individually. It is the same as the distributive property of multiplication over subtraction, except it will give the difference.
Question 5
[tex]2.4(3x + 2y) - 1.5(4x - 5y)[/tex]
Use the distributive property:
[tex]7.2x+4.8y-6x+7.5y[/tex]
[tex]1.2x+12.3y[/tex]
Question 3
[tex]$\frac{2}{5} \left(4x-\frac{3}{4}y \right)$[/tex]
Use the distributive property again:
[tex]$\frac{8}{5}x -\frac{6}{20}y $[/tex]
[tex]$\frac{8}{5}x -\frac{3}{10}y $[/tex]
Now you have to convert [tex]$\frac{8}{5} $[/tex] to mixed form:
It will give 1 with remainder 3, therefore
[tex]$\frac{8}{5} = 1\frac{3}{5} $[/tex]
[tex]$1\frac{3}{5}x -\frac{3}{10}y $[/tex]
Question 2
[tex]$\frac{4}{5} x +\frac{2}{3} x$[/tex]
[tex]$\frac{4(3)}{5(3)} x +\frac{2(5)}{3(5)} x$[/tex]
[tex]$\frac{12}{15} x +\frac{10}{15} x$[/tex]
[tex]$\frac{22}{15} x$[/tex]
Mixed form again:
[tex]$1\frac{7}{15} x$[/tex]
Question 1
[tex]$\frac{3}{4} (8x-4y) -\frac{2}{3} (12x - 9y)$[/tex]
[tex]$6x-3y -8x +6y$[/tex]
