If you multiply 0.2 by 3, you get 0.6
If you multiply 0.6 by 3, you get 1.8
If you multiply 1.8 by 3, you get 5.4
If you multiply 5.4 by 3, you get 16.2
If you multiply 16.2 by 3, you get 48.6

Consider the equation:
6x+55=x^2
1) Rewrite the equation by completing the square.
Your equation should look like (x+c)^2=d(x+c)
2
=dleft parenthesis, x, plus, c, right parenthesis, squared, equals, d or (x-c)^2=d(x−c)
2
=dleft parenthesis, x, minus, c, right parenthesis, squared, equals, d.
2) What are the solutions to the equation?
Step-by-step explanation:
1.
Subtract the coefficient from both sides, keep 55 on the same side.
[tex] {x}^{2} - 6x = 55[/tex]
Complete the square by dividing the coefficient by two and squaring it.
[tex] {x}^{2} - 6x + 9 = 55 + 9[/tex]
Use binomial to factor the left side.
[tex](x - 3) {}^{2} = 64[/tex]
2. Solve for x.
[tex](x - 3) = 8[/tex]
[tex]x = 11[/tex]
Remeber the square root of 64 is also -8 so
[tex]x - 3 = - 8[/tex]
[tex]x = - 5[/tex]
So the solutions are -5 and 11
Answer:
Answers
1) We can rewrite the equation as 64=(x−3)^2
2) The solutions to the equation are x=3±8

Put the following equation of a line into slope-intercept
form, simplifying all fractions.
x + 4y = 24
ASAP!!!!
Answer:
y = -1/4x + 6
Step-by-step explanation:
Answer:
y = -1/4x + 6
Step-by-step explanation:
Get y alone:
x + 4y = 24
-x = -x
4y = -x + 24
Divide:
4y = -x + 24
4 = 4
Distribute division:
y = -1/4x + 24/4
Reduce fractions:
y = -1/4x + 6

Find the surface area of this rectangular prism 4ft, 8ft, 2ft
Answer:
112ft^2
Step-by-step explanation:
A = 2(wl+hl+hw)
A = 2[(4)(8)+(2)(4)+(2)(8)]
A = 2(32+8+16)
A = 2(56)
A = 112

Solve for x. Show your work. -12x < -12
Step-by-step explanation:
-12x < -12
-12x/-12= x
-12/-12= 1
x < 1
-12x < -12
Divide both sides by -12 and because you are dividing by a negative number you need to reverse the inequality sign.
The answer becomes x > 1
Use the drawing tools to form the correct answer on the graph.
Graph the line that represents this equation:
3x-4y=8
Answer:
See attachment for graph
Step-by-step explanation:
Given
[tex]3x - 4y = 8[/tex]
Required
Graph the line
First, we calculate the intercepts
Set x = 0
So:
[tex]3x - 4y = 8[/tex]
[tex]3*0 - 4y = 8[/tex]
[tex]- 4y = 8[/tex]
Divide by -4
[tex]y = -2[/tex]
So, we have:
[tex](x,y) = (0,-2)[/tex]
Next, set y = 0
So:
[tex]3x - 4y = 8[/tex]
[tex]3x - 4 * 0 = 8[/tex]
[tex]3x = 8[/tex]
Divide by 3
[tex]x = 8/3[/tex]
So, we have:
[tex](x,y) = (8/3,0)[/tex]
The graph to be plotted must pass through [tex](x,y) = (0,-2)[/tex] and [tex](x,y) = (8/3,0)[/tex]

Mistakes made
The likes terms weren't combined -6x was incorrect. -2x+4x = 2, when adding negative and positive numbers you subtract, the sign takes the number with the larger value which is +4 so the answer should be positive +Find the zeros of the quadratic function: y= 6(7x + 9)(8x - 3).
A) (-9/7,0), (3/8,0)
B)(-7/9,0), (8/3,0)
C) (-3/8,0), (°/7,0)
D) (-8/3,0), (7/9,0)
Answer:
A) (-9/7,0), (3/8,0)
Step-by-step explanation:
Zeros of a quadratic function:
x for which y = 0.
In this question:
[tex]y = 6(7x + 9)(8x - 3)[/tex]
It's 0 if one of the factors is 0. 6 is never 0, now about the other to:
[tex]7x + 9 = 0[/tex]
[tex]7x = -9[/tex]
[tex]x = -\frac{9}{7}[/tex]
So (-9/7, 0) is a zero of the quadratic function.
The other is:
[tex]8x - 3 = 0[/tex]
[tex]8x = 3[/tex]
[tex]x = \frac{3}{8}[/tex]
(3/8,0) is the other zero.
Thus, the correct answer is given by option A.

Use y = mx + b to determine the equation of a line with a slope -5, passing through the point (-2,4).
Answer:
[tex]y=-5x-6[/tex]
Step-by-step explanation:
Hi there!
In [tex]y=mx+b[/tex], m is the slope of the line and b is the y-intercept (the value of y when x is 0). y and x remain the same but m and b are replaced with numbers.
Given that the slope is -5, plug it into [tex]y=mx+b[/tex]:
[tex]y=-5x+b[/tex]
Now, to solve for b, plug in the given point (-2,4):
[tex]4=-5(-2)+b\\4=10+b[/tex]
Subtract 10 from both sides to isolate b:
[tex]4-10=10+b-10\\-6=b[/tex]
Therefore, the y-intercept of this line is -6. Plug this back into [tex]y=-5x+b[/tex] as b:
[tex]y=-5x-6[/tex]
I hope this helps!
