Which of the following numbers is not a perfect square?
a. 49
b. 121

Answer:
C. 125Step-by-step explanation:
49 = 7×7 ← a perfect square
121 = 11×11 ← a perfect square
144 = 12×12 ← a perfect square
but:
125 = 5×5×5 = 5√5×5√5 and 5√5 is not integer so 125 is not a perfect square

Solve for the line, Thank you!
Cydney is proving that perpendicular lines have slopes that are opposite reciprocals. She draws line p and labels two points on the line as (0, a) and (b, 0). Enter the answers, in simplest form, in the boxes to complete the proof. The slope of line p is . Rotate line p 90° counterclockwise about the origin to get line q. The labeled points on line p map to (−a, 0) and ( , ) on line q. The slope of line q is . The slopes of the lines are opposite reciprocals because the product of the slopes is .
Answer:
Slope of p = -a/b
(0, b) is on line q
Slope of q = ( b - 0) / (0 - -a) = b/a
Product of the slopes = (-a/b) (b/a) = (-ab) /(ab) = -1

Answer: z=2
Step-by-step explanation:
2 x 2 = 4 + 3 = 7
Answer: Okay, the answer is z=2.
Step-by-step explanation: Step 1: Simplify the both sides of the equation: 2z+3=7.
Step. 2: Subtract 3 from the both sides: 2z+3−3=7–3.
Last but not least is step 3. Divide the both sides by 2: 2z/2=4/2. So you get z=2. I hoped my step-by-step explanation formula substitution is very helpful, please mark me as Brainliest, and have a happy holidays!!!!!!! :D

Kwame is not sure whether to use a line graph or a line plot to display the data. Which best explains which graph is a better representation of the data?
The line graph because it shows how the number of miles increases over the number of minutes.
The line graph because the numbers in the data table are equally spaced.
The line plot because numbers can be plotted on a number line.
The line plot because there are only a few data points.
Answer:
The line graph because it shows how the number of miles increases over the number of minutes.
Step-by-step explanation:
ake it or leave it
The best explanation graph is a better representation of the data below: "The line graph because it shows how the number of miles increases over the number of minutes."
What is a graph?A graph can be defined as a visual representation or a diagram that represents data or values.
The distance in miles a car travels over time in minutes is shown in the table.
Distance (miles) Time (minutes)
10 15
20 30
30 45
40 60
A line graph is a good choice for representing data that show a change in value over time. In this case, the value being measured is the distance in miles traveled, and the time is being used as the variable. A line graph is a good choice because it can show the change in distance over time, which is what the data represents.
Hence, the correct answer would be an option (A).

Answer:
m∠CAB = 62°
m∠CBG = 114°
Step-by-step explanation:
Given:
the above figure
Find:
What are the measures of angles CAB and CBG
Solution:
The total angle at C is 32°+52° = 84°. We know that "remote interior" angles ECB and EBE have a sum that matches angle CEF.
So, angle CBE = 150° -84° = 66°
Angle CBG is the supplement of this, so is ...
m∠CBG = 180° -66° = 114°
That angle is the total of "remote interior" angles BCA and CAB. So angle CAB is ...
m∠CAB = 114° -52° = 62°
there is a certain number. If you add 30 7 to it, then subtract 22 7 from the previous result, and then subtract that difference from 59/7, after that you will get 19 7. What is a certain number?
Step-by-step explanation:
59 / 7 - ( x + 30 / 7 - 22 / 7 ) = 19 / 7
59 / 7 - ( x + 8 / 7 ) = 19 / 7
59 / 7 - x - 8 / 7 = 19 / 7
- x = 19 / 7 - 59 / 7 + 8 / 7
- x = - 32 / 7
x = 32 / 7

The coordinates of the point P is (6/5, 17/5).
Given that, the points A(-2, 5) and B(2, 3) and the line segment divided in the ratio 4:1.
What is the section formula?The Section formula is used to find the coordinates of the point that divides a line segment (externally or internally) into some ratio.
The section formula is [tex]P(x,y)=(\frac{mx_{2}+nx_{1} }{m+n}, \frac{my_{2}+ny_{1} }{m+n} )[/tex].
Here, m:n=4:1, (x1, y1)=(-2, 5) and (x2, y2)=(2, 3)
Now, P(x, y) = [tex](\frac{4\times 2+1 \times (-2)}{4+1} , \frac{4\times 3+1 \times 5}{4+1} )[/tex]
=(6/5, 17/5)
Therefore, the coordinates of the point P is (6/5, 17/5).

Bobs new bike has 26 inch diameter wheels.what is the circumference of the new wheel.Give answer to 1 decimal place
Answer:
The circumference of Bob's new wheel is 81.7 inches
Step-by-step explanation:
Circumference of a circle
The circumference of a circle of radius r is given by:
[tex]C=2\pi r[/tex]
The radius is half the diameter:
r = d / 2 = 26 / 2 = 13
r = 13 inch
Now calculate the circumference:
[tex]C=2\cdot\pi\cdot 13[/tex]
Calculating:
[tex]C=81.7\ inch[/tex]
The circumference of Bob's new wheel is 81.7 inches

factor x to the fourth-5x squared+4
Answer:
Work shown below!
Step-by-step explanation:
[tex]x^{4}-5x^{2} +4[/tex] = [tex]0[/tex]
[tex]A[/tex] = [tex]x^{2}[/tex]
[tex]A^{2} -5A+4[/tex] = [tex]0[/tex]
[tex](A-1)(A-4)[/tex] = [tex]0[/tex]
[tex](x^{2}-1)(x^{2} -4) =0\\(x-1)(x+1)(x-2)(x+2)=0[/tex]
x - 1 = 0
Add 1 to both sides;
x = 1
x + 1 = 0
Subtract 1 from both sides;
x = -1
x - 2 = 0
Add 2 to both sides;
x = 2
x + 2 = 0
Subtract 2 from both sides;
x = -2
What is the solution to this system of linear equations?
x + y = 4
x − y = 6
Answer:
x=5 , y= -1
Step-by-step explanation:
You can see that one of the y's is negative while the other is positive, so you can add them together.
Now, negative 1 + positive 1 = 0, so the y's cancel out leaving only the x's.
Remember you can't add one part without adding the other so x+x = 2x, and 4+6=10. This makes the final equation 2x=10.
You can simplify that into x=5. This gives you the answer for x
Then substitute x=5 into any of the two equations (doesn't matter) I'll use the first one. So if you substitute it you get 5+y=4.
Simplified, y= -1
Therefore, x= 5 and y=-1

I REALLY NEED HELP QUICK!
Answer:
y=1/2x-5
Step-by-step explanation:
From the picture you can see that (0, -5) is a point on the function and that (2, -4) is another point. Using these you can find the slope of the function with the equation
[tex](y_{2} -y_{1})/(x_{2}-x_{1} )[/tex]
We can substitute in the points so it looks like
[tex](-4--5)/(2-0)[/tex] or [tex]1/2[/tex] which is the slope of the function
Now, since the y-intercept is (0, -5) on the graph, the b part in the slope-intercept form of the equation would be -5, leaving us with the equation y=1/2x-5
