Step-by-step explanation:
Tom determines that the system of equations below has two solutions, one of which is located at the vertex of the parabola.
Equation 1: (x – 3)2 = y – 4
Equation 2: y = -x + b
In order for Tom’s thinking to be correct, which qualifications must be met?
b must equal 7 and a second solution to the system must be located at the point (2, 5).
b must equal 1 and a second solution to the system must be located at the point (4, 5).
b must equal 7 and a second solution to the system must be located at the point (1, 8).
b must equal 1 and a second solution to the system must be located at the point (3, 4).
Answer:
your answer is:
b must equal 7 and a second solution to the system must be located at the point (2, 5).

Sally sold half of her comic books and then bought eight more. She now has twelve. How many did she begin with?
Answer:
8
Step-by-step explanation:
Since she now has 12, subtract 8 because of the 8 she before added.
Now, you're left with 4.
The 4 is half of what she originally had, leading up to the fact that the answer is 8.
Sally began with eight comic books.

What is a negative plus a positive
Answer:
When you are adding a negative number to a positive number you are effectively subtracting the second number from the first. ... And then you add the negative number, which means you are moving to the left – in the negative direction. Basically you are subtracting the 2. The answer is 2.

What is double angle formula for tan?Let, 'm' be an angle then the double angle formula of tan is,
[tex]tan(2m)=\frac{2~tan(m)}{1-tan^{2}m }[/tex]
For given example,
We have cos(x) = 1/√5 and sin(x) > 0
We know, sin^2(x) + cos^(x) = 1
⇒ sin^2(x) = 1 - (1/√5)^2
⇒ sin^2(x) = 1 - (1/5)
⇒ sin^2(x) = 4/5
⇒ sin(x) = ± 2/√5
But sin(X) > 0
⇒ sin(x) = 2/√5
We know, for any angle Ф,
tan(Ф) = sin(Ф) / cos(Ф)
Hence, tan(x) = sin(x)/cos(x)
tan(x) = (2/√5) / (1/√5)
⇒ tan(x) = 2/1
⇒ tan(x) = 2
Now, using the double angle formula for tan,
[tex]\Rightarrow tan(2x)=\frac{2~tan(x)}{1-tan^{2}x }\\\\\Rightarrow tan(2x)=\frac{2\times 2}{1-(2)^{2}}\\\\ \Rightarrow tan(2x)=\frac{4}{1-4}\\\\ \Rightarrow \bold{tan(2x)=-\frac{4}{3}}[/tex]
Therefore, the value of tan(2x) is -4/3

For every 3 dozen cookies, a bakery uses 8 cups of butter. How many dozen of cookies could you make with 20 cups of butter?
Answer:
7 1/2 dozen of cookies
Step-by-step explanation:
If for every 3 dozen cookies, a bakery uses 8 cups of butter then we can say;
3 dozens cookies = 8 cups of butter
x cups of cookies = 20 cups of butter
Cross multiply
8*x = 3 * 20
8x = 60
x = 60/8
x = 7 4/8
x = 7 1/2
Hence you will need 7 1/2 dozen of cookies

A dime rolls 41.8 cm. How many rotations did it make?
Answer:
to figure this out you would need to know the circumference of the dime. then divide 41.8 by the circumference.
Step-by-step explanation:
if the circumference is aprox. 2.2 inches, then you would divide 41.8 by 2.2.
One year after you buy a tree, it is 10 feet tall. Each year after you buy the tree, it grows 2 feet. Write a function that represents the arithmetic sequence (1,10),(2,12),(3,14). How long does it take for the tree to reach its maximum height of 28 feet?
Answer:
10 years
Step-by-step explanation:
We are told that One year after you buy a tree, it is 10 feet tall. Thus, it's initial height after 1 year is 10 ft.
Now we are told that each year after you buy the tree, it grows 2 feet. This means that it's height after you bought it was; f(0) = 10 - 2 = 8ft
Thus,
f(1) = 8 + 2 = 10
f(2) = 8 + 2 + 2 = 12
f(3) = 8 + 2 + 2 + 2 = 14
The pattern here is;
f(x) = 8 + 2x
Where x is number of years
Thus, for it to reach a maximum height of 28 ft;
28 = 8 + 2x
Subtract 8 from both sides to give;
28 - 8 = 2x
2x = 20
x = 20/2
x = 10 years

The graph of a linear relationship passes through (0, 3), and (3, 9). Which is an equation for this linear relationship?
Step-by-step explanation:
1. First calculate for the gradient m
2. Calculate for the constant C by using any point (0,3) or (3,9)
3. Lastly, put the values found in the equation y = mx + c
1. m = Y2-Y1/X2-X1
=9-3/3-0=2
2. input one point together with m into the equation y=mx+c
3=2(0)+C
C=3
3. Therefore equation of linear relationship is
y = 2x + 3

Answer:
XZ ≈ 14.4 cm
Step-by-step explanation:
Using the cosine ratio in the right triangle, that is
cos29° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{YZ}{XZ}[/tex] = [tex]\frac{12.6}{XZ}[/tex] ( multiply both sides by XZ )
XZ × cos29° = 12.6 ( divide both sides by cos29° )
XZ = [tex]\frac{12.6}{cos29}[/tex] ≈ 14.4 cm ( to 3 significant figures )

What is the leading coefficient of the polynomial?
15x^4 – 26x^3 – 18x^6 – 19x^7
Answer:
-19
Step-by-step explanation:
Rewrite the equation from highest exponent to lowest:
-19x^7-18x^6+15x^4-26x^3
Coefficients are the numbers in front of the exponent, so the leading coefficient is what is attached to the highest exponent value.
-19x^7 is the highest exponent, so -19 is the highest coefficient.
