let's recall that, on the number line, for the positive side, the farther from zero, the larger the number, thus 100 is a much larger number than 10.
now, on the negative side of the number line, the farther from zero, the smaller the number, thus -1 is much much larger number than -1,000,000,000.
is -3 ≥ -15, is -3 larger or equals to -15, well, certainly is not equal but is certainly larger, yes.

I WILL GIVE BRAINLIEST
Answer:
The measure of angle ABC is 34°
Step-by-step explanation:
we know that
The measurement of the outer angle is the semi-difference of the arcs it encompasses.
so
∠ABC=(1/2)[major arc AC-minor arc AC]
∠ABC=(1/2)[major arc AC-146°]
Find the measure of major arc AC
major arc AC=360°-146°=214°
substitute
∠ABC=(1/2)[214°-146°]=34°

The formula for the circumference of a circle is C = 2tr,
where r is the radius and C is the circumference. The
equation solved for r is r= .
The correct formula to calculate the circumference of a circle is C = 2πr. To solve for r, the radius, we can rearrange the equation to r = C/(2π), which can be used to find the radius when the circumference is known.
Explanation:The formula for the circumference of a circle is given by C = 2πr, where 'C' represents the circumference and 'r' is the radius of the circle. The formula has been provided in an errorneous format, it should be 2πr not 2tr.
If we want to solve this equation for 'r', which represents the radius, we would need to isolate 'r' on one side of the equation. We can do this by dividing both sides of the equation by 2π. The resulting equation solved for r would be r = C/(2*π).
This equation can be utilized to find the radius if the circumference is known.

What are the zeros of the function f(x)=x^2+x-6 divides by x^2-x-6?
Answer:
It is B.
Step-by-step explanation:
x^2+x-6 / x^2-x-6 = 0
The numerator equates to zero:
x^2 + x - 6 = 0
(x + 3)(x - 2) = 0
the zeroes are {-3, 2).
The zeroes of the function f(x) = (x² + x - 6)/(x² - x - 6) are -3, 2.
Hence, option B. is the right choice.
What are functions?A function (say f(x)) is defined over x, when an expression in x, gives only one value f(x) for all the x in its domain.
What are zeroes of function?A zero of a function (say f(x)) is the value x, where f(x) = 0.
How do we solve the given question?We are asked to find the zeroes of the function
f(x) = (x² + x - 6)/(x² - x - 6).
To find the zeroes, we put the value of f(x) = 0, in the above equation to get:
(x² + x - 6)/(x² - x - 6) = 0
or, (x² + 3x - 2x - 6)/(x² + 2x - 3x - 6) = 0
or, {x(x + 3) -2(x + 3)}/{x(x + 2) -3(x + 2)} = 0
or, {(x - 2)(x + 3)}/{(x - 3)(x + 2)} = 0
Zeroes are where the numerator = 0, as the denominator can not be 0.
∴ (x + 3)(x - 2) = 0
∴ Zeroes of the function x + 3 = 0 ⇒ x = -3, and x - 2 =0 ⇒ x = 2, that is
-3, 2. Hence, option B. is the right choice.

The vertex form of the quadratic equation is y = (x-3)^2 + 3.
Explanation:The vertex form of a quadratic function is given by y = a(x-h)^2 + k, where (h,k) represents the coordinates of the vertex. To convert the quadratic equation y = x^2-6x+6 into vertex form, we need to complete the square.
First, let's group the terms with x together: y = (x^2-6x) + 6.To complete the square, take half the coefficient of x (-6), square it (-6/2)^2 = 9, and add it inside the parentheses: y = (x^2-6x+9) - 9 + 6.Simplify the equation: y = (x-3)^2 + 3.

Point W is located on QR so that QW/QR = 3/4. What are the coordinates of point W?
Answer:
(9,9)
Step-by-step explanation:
I like to use similar triangles.
To take some confusion out of of this let's translate the line down 3 units and left 3 units.
Alright from the drawing we get:
a/8 = b/8 and a/8 = 3k/4k (or b/8=3k/4k )
We don't need the k's, they cancel.
a/8 = b/8 and a/8=3/4
So the first equation means a=b.
Now let's see what a and b are by solving a/8 = 3/4.
Cross multiply:
[tex]\frac{a}{8}=\frac{3}{4}[/tex]
[tex]a(4)=8(3)[/tex]
[tex]4a=24[/tex]
a=6
So if a=b and a=6, then b=6.
The ordered pair is (6,6).
Now let's move the line back.
We have to move it up 3 units and right 3 units which gives us the point (9,9).

3 4 (20y − 8) + 5 = 1 2 y + 1 4 (20y + 8)
15y − 6 + 5 = 1 2 y + 5y + 2
15y − 1 = 11 2 y + 2

A. Combine like terms 11/2 and 2
B. Distribute 15 to each term on the left side.
C. Subtract 11/2y from each side of the equation.
D. Divide each side of the equation by 2.
Answer:
C.
Step-by-step explanation:
Your fractions are missing there fraction bars:
3/4 (20y − 8) + 5 = 1/2 y + 1/4 (20y + 8)
15y − 6 + 5 = 1/2 y + 5y + 2
15y − 1 = 11/2 y + 2
A. 11/2y and 2 aren't like terms because one contains the variable y and the other contains no variable
B. The distribute property can't be used there because you don't have 15(y-1) you have 15y-1
C. Subtracting 11/2y sounds like a good step because there is a y term on the opposing side.
15y-1=11/2y+2
Subtracing 11/2y on both sides
9.5y-1=2
That looks pretty good because then you would add 1 on both sides giving:
9.5y =3
Last step would get the y by itself which is dividing both sides by 9.5 giving you 6/19.
D. You could actually do this but it doesn't help you get x by itself. The equation would look like this: 15/2 y-1/2=11/4 y+1
Answer:
C. Subtract 11/2y from each side of the equation.

Misaka solved the radical equation x – 3 = square root of 4x-7 but did not check her solutions. (x – 3)2 = square root of 4x-7^2 x2 – 6x + 9 = 4x – 7 x2 – 10x + 16 = 0 (x – 2)(x – 8) = 0 x = 2 and x = 8 Which shows the true solution(s) to the radical equation x – 3 = square root of 4x-7 x = 2 x = 8 x = 2 and x = 8 There are no true solutions to the equation.
Answer:
x=8 is a true solution of the radical equation
Step-by-step explanation:
we have
[tex]x-3=\sqrt{4x-7}[/tex]
Solve for x
squared both sides
[tex](x-3)^{2}=4x-7\\\\x^{2}-6x+9=4x-7\\\\ x^{2}-10x+16=0[/tex]
Convert to factored form
[tex]x^{2}-10x+16=(x-2)(x-8)[/tex]
The solutions are x=2 and x=8
Verify the solutions
For x=2
Substitute in the original equation
[tex]2-3=\sqrt{4(2)-7}[/tex]
[tex]-1=1[/tex] ----> is not true
therefore
x=2 is not a true solution of the radical equation
For x=8
Substitute in the original equation
[tex]8-3=\sqrt{4(8)-7}[/tex]
[tex]5=5[/tex] ----> is true
therefore
x=8 is a true solution of the radical equation
The true solution to the radical equation is x = 8, after checking the potential solutions by substituting them back into the original equation.
Explanation:The student is asked to find the true solution(s) to the radical equation x – 3 = square root of 4x-7. The student has solved the equation, but it is essential to check the solutions by substituting them back into the original equation to ensure they are not extraneous. The student got x = 2 and x = 8 as potential solutions. We must substitute these values back into the original equation to determine their validity:
For x = 2: 2 – 3 does not equal the square root of (4(2) – 7), so x = 2 is not a solution.For x = 8: 8 – 3 does equal the square root of (4(8) – 7), so x = 8 is a solution.Hence, the only true solution to the radical equation x – 3 = square root of 4x-7 is x = 8.

Can some help?
Answer:
[tex]f(x)=2(x-2)^{3}(x+2)^{2}[/tex]
Step-by-step explanation:
we know that
2 is a zero of multiplicity 3 of the polynomial
so
we have that
x=2 is a solution of the polynomial
A factor of the polynomial is
[tex](x-2)^{3}[/tex] ----> is elevated to the cube because is a multiplicity 3
and the other solution is x=-2
since the polynomial is fifth degree, x=-2 must have a multiplicity 2
so
the other factor of the polynomial is
[tex](x+2)^{2}[/tex] ----> is squared because is a multiplicity 2
therefore
The polynomial is equal to multiply the factors by the leading coefficient
so
[tex]f(x)=2(x-2)^{3}(x+2)^{2}[/tex]

Step-by-step explanation:
So you are asked to find 3f(1)-4g(-2).
In order to find this you must first find f(1) and g(-2).
So f(1) means what is the value of the expression 3x-2 for when x=1.
f(1)=3(1)-2
f(1)=3-2
f(1)=1
And g(-2) mean what is the value of the expression 5-x^2 for when x=-2.
g(-2)=5-(-2)^2
g(-2)=5-(4)
g(-2)=5-4
g(-2)=1
So both of those function values were 1.
Our problem of 3f(1)-4g(-2) becomes 3(1)-4(1)=3-4=-1.

Find the equation of the line through (2,9)(1,6)(-7,-6)
Answer:
y=(3/2)x+6
If your equation is in a different form, let me know.
Step-by-step explanation:
So the slope-intercept form of a line is y=mx+b where m is the slope and b is the y-intercept.
Parallel lines have the same slope, m (different y-intercept (b) though).
So we need to find the slope going through (1,6) and (-7,-6).
To do this you could use [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].
Or, what I like to do is line the points up vertically and subtract vertically then put 2nd difference over first difference. Like so:
( 1 , 6)
-( -7, -6)
---------------
8 12
So the slope of our line is 12/8.
Let's reduce it! Both numerator and denominator are divisible by 4 so divide top and bottom by 4 giving 3/2.
Again parallel lines have the same slope.
So we know the line we are looking for is in the form y=(3/2)x+b where we don't know the y-intercept (b) yet.
But we do know a point (x,y)=(2,9) that should be on our line.
So let's plug it in to find b.
y=(3/2)x+b with (x,y)=(2,9)
9=(3/2)2+b
9=3 +b
Subtract 3 on both sides:
9-3=b
6=b
So the equation in slope intercept form is y=(3/2)x+6
