Answer:
x = 6 ± [tex]\sqrt{2}[/tex]
Step-by-step explanation:
To find the zeros equate f(x) to zero , that is
2(x - 6)² - 4 = 0 ( add 4 to both sides )
2(x - 6)² = 4 ( divide both sides by 2 )
(x - 6)² = 2 ( take square root of both sides )
x - 6 = ± [tex]\sqrt{2}[/tex] ( add 6 to both sides )
x = 6 ± [tex]\sqrt{2}[/tex]
The zeros are x = 6 - [tex]\sqrt{2}[/tex] , x = 6 + [tex]\sqrt{2}[/tex]

A carpenter needs 5 1/2 strips of lumber for a project If each strip measures $ meter, how many meters of lumber does the carpenter need in all?
Answer:
A carpenter needs 4 1/3 strips of lumber for a project. Each strip is to measure 1/3 meter.
Step-by-step explanation:
Answer:
5 1/2 meters because 5 x 1/2 gives 11/2 so mixed fraction will be 5 1/2

Which sequence of transformations proves that shape I is similar to shape II?
ОА.
a reflection across the x-axis, and then a translation 6 units right
B.
translation 6 units rightand then a 90° clockwise rotation about the origin
Ос.
a 180° counterclockwise rotation about the origin
OD
a reflection across the y-axis, and then a translation 4 units up
OE.
a reflection across the x-axis, followed by a 180° counterclockwise
rotation about the origin, and then a translation 4 units down
Answer:
I would say OD
Step-by-step explanation:
if you reflect shape l across the y-axis
then move shape ll up 4 spaces
they will line up
Answer:
This is easy. It's option E. Trust me, I have this question on my finals. Good luck :)

If C is the length of the hypotenuse of a right triangle and A and B are the leg lengths.
Please pick the “incorrect” answer in the following answers from the picture above.
If they are all correct please let me know!
Answer:
They are all correct
Step-by-step explanation:
c^2 = a^2 + b^2 = pythagorean theorem
if subtract b^2 from both sides = a^2 = c^2 - b^2
if subtract a^2 from both sides then square root both sides = b = sqrt(c^2 - a^2)
All are correct
Pythagorean theorem states that
In a right angle triangle the square of the hypotenuse is equal to the sum of squares of base and perpendicular.

Which graph represents y=⌈x⌉over the domain 2≤x≤5 ?
Answer:
4
Step-by-step explanation:
#1 has to be excluded, since it jumps from 4 to 5 and has a hole between x=4 and x=5
#2 loses the extreme values. It would be correct if the domain was [tex]2<x<5[/tex]
#3 is including values in the interval [tex]1<x \leq 2[/tex] which aren't in our domain.
#4 is the remaining one.
1 3/7 make inproper plzzzzzzzz help FASTTTT
Answer:
Step-by-step explanation:
1 3/7 is 59/3 is 59/3!!!!
Answer:
10/7
Step-by-step explanation:
An improper frraction is a fraction where the numerator is greater than the denominator, such as 4/3 or in this case, 10/7. 1 converts to 7/7, so you add 7/7 with 3/7 to get 10/7.

Use the graph to determine the domain and range. Then state whether the relation is a function.
What is the range of the function?
Answer:
D = {-2≤x≤4}
R = {0≤x<2}
It is a function
Step-by-step explanation:
How to find domain and range from co-ordinate pairs?
If (x,y) is a pair x is domain,y is range.Now starting and ending point on x axis
(-2,0)(4,0)Hence
[tex]\ \ \sf\longmapsto D_f=\{-2,4\}[/tex]
Starting and ending point on y axis
(0,0)(0,-3)Hence

Jim is running on a trail that is 7/8 of a mile long. So far he has run 4/5 of the trail. What fraction of a mile has he run so far?
Answer:
7/10
Step-by-step explanation:
4/5 of 7/8 means we can multiply the fractions to get the answer
28/40 can be simplified by dividing by 4 to get: 7/10

What is the slope and y-intercept -4x+2y=-2
Answer:
Slope: 2
Y-intercept: (0, -1) or - 1
Step-by-step explanation:
Given the linear equation, -4x + 2y = -2:
Transform the given equation into its slope-intercept form, y = mx + b:
-4x + 2y = -2
Add 4x to both sides:
-4x + 4x + 2y = 4x - 2
2y = 4x - 2
Divide both sides by 2 to isolate y:
[tex]\frac{2y}{2} = \frac{4x - 2}{2}[/tex]
y = 2x - 1 ⇒ This is the slope-intercept form where the slope, m = 2, and the y-intercept is (0, -1).

One movie club charges a $100 membership fee and $10 for each movie. Another charges no membership fee but movies are $15 each. Write and solve an equation to find the number of movies you need to buy for the cost of each movie club to be the same.
If you take a varible, lets say x, and times that by your mom. You will get y^2. After that, take ur mom and divide that by ur dads ding dong. Now they don't give us the formula to find out how long, creamy and wet your dad's ding dong is so we use the formula, busty step sis + step bro = BIG DING DONG, to get (x^69)+12 as ur dads ding dong. Now add ur mom with ur dad, y^2+(x^69) to get a child, 6969699696.
Hope this helps :)

(1, 3) and (-3, -5)
write a linear equation given the two points
Answer:
y = 2x + 1
Step-by-step explanation:
1. Find the slope; (change in y values)/(change in x values)
Slope = (-5 - 3)/ (-3 - 1) = -8/-4 = 2
2. Find the y-intercept (b) using the slope intercept formula: y = mx + b
m = 2 and using point (1, 3) , solve for "b"
y = mx + b
3 = 2(1) + b
3 = 2 + b
1 = b
3. Write the linear equation: y = 2x + 1

There are men and women at a meeting.
There are 42 women.
40% of the people at the meeting are men.
Work out the total number of people at the meeting.
Answer:
70 peopleStep-by-step explanation:
40% of people are men, then 60% are women.
60% of x is 42 people, find x:
0.6x = 42x = 42/0.6x = 70Let total people be x

parallel, perpendicular, neither. 10x+8y=16 5y=4x-15
Answer:
Neither.
Step-by-step explanation:
The slope of the first equation is -4/5 and the slope of the second equation is 4/5. Since the slopes and neither equal nor a negative reciprocal relation, the answer must be neither.
[tex]\boxed{\sf m+14=3}[/tex]
Step-by-step explanation:
In order to find the value of m, we will do the opposite of positive 14 and subtract it on both sides. Now we have m = -11.
Hope this helps :)
Answer:
m = -11
Step-by-step explanation:
m+14 = 3m+14-14 = 3-14m = -11Solve for x:
42=3x+6
Question 2 options:
x=-16
x=16
x=12
x=14
Answer:
42=3x+6
subtract 6 from both sides
42-6=3x+6-6
to get
36=3x
divide both sides by 3 to isolate x
36/3=3x/3
to get
12=x
