The graphs of f(x) and g(x) are shown below:
If f(x) = (x + 7)2, which of the following is g(x), based on the translation?
Hint: How many units is g(x) shifting down of f(x)?
a
g(x) = (x + 9)2
b
g(x) = (x + 5)2
c
g(x) = (x + 7)2 + 2
d
g(x) = (x + 7)2 − 2
Answers
Answer:
d
Step-by-step explanation:
Comparing the graphs we understand :
⇒ g(x) is equal to f(x) when shifted down 2 units
===========================================================
Hence :
⇒ g(x) = f(x) - 2
⇒ g(x) = (x + 7)² - 2
A line connecting the points (-3,0) and (x, -6)has slope -1. Determine x.
Answers
Answer:
x=3
Step-by-step explanation:
We can use the slope formula to help complete this question
m = (y2-y1)/(x2-x1)
-1 = ( -6-0)/(x- -3)
-1 = -6/ (x+3)
Multiply each side by (x+3)
-x-3 = -6
Add 3 to each side
-x -3+3 = -6+3
-x =-3
Multiply each side by -1
x = 3
Answer:
x = 3
Step-by-step explanation:
The given slope and point can be used to write the equation of the line using the point-slope form. To find x for a given y, we can solve that equation.
__
setupThe point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
For (h, k) = (-3, 0), and m = -1, the equation is ...
y -0 = -1(x -(-3))
y = -x -3
We want x when y = -6, so this becomes ...
-6 = -x -3
solutionAdding x+6 to both sides of the equation, we get ...
(x +6) -6 = -x -3 +(x +6)
x = 3 . . . . . . . simplify

(x-h)²+(y-k)²=r²(x+6)²+(y+5)²=(√17)²(x+6)²+(y+5)²=17Option A
Answer:
Step-by-step explanation:
Consider the end points (-7,-1) and (-5,-9)
The center is the mid point between these two points.
The value of center is,
(h,k) = ((-7-5)/2, (-1-9)/2)
(h,k) = (-12/2,-10/2)
(h,k) = (-6, -5)
If the center (h,k) = (-6, -5) and radius is r then the equation of the circle is,
Equation of Circle,
((x-h)^2)+((y-k)^2) = r^2
((x+6)^2)+(y+5)^2 = r^2
Hence, the answer is ((x+6)^2)+(y+5)^2 = r^2.

How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
Let we suppose that:
Swimmer A swam x laps
Swimmer B swam y laps.
Then, according to the given data, we have:
x + y = 175 laps
y = 25 + 2x
(25 more than twice of laps of A is the number of laps of B).
Thus, we get a system of two equations:
x + 25 + 2x = 175
3x + 25 = 175
3x = 175 - 25 = 150
x = 50
As x is the number of laps Swimmer A swam, thus, the number of laps that Swimmer A swam was 50 laps.

What is compound interest?It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
According to table, $40,000 falls in the 3rd category between $31,850 and $77,100
And, The tax is "$4,386.25 + 25% of amount over 31,850"
Hence, we have:
= $4,386.25 + 25% of (40,000 - 31,850).
= $4,386.25 + 0.25 x 8150
= $6423.75

14. Write the converse of each statement and then determine whether or not the converse is true.
Answers
Part A
Converse = "If corresponding angles are equal, then two lines are parallel"Result = TrueExplanation:
Refer to the converse of the corresponding angles theorem. The original version is stated as part A, and the converse is marked in bold above.
Conditional statements are of the form "if this, then that". Symbolically we can use the template "If P, then Q". The P and Q are placeholders for logical statements.
The converse of "if P, then Q" is "If Q, then P". We swap the positions of P and Q. Do not negate either piece.
========================================================
Part B
Converse = "If angle C is 70 degrees, then the sum of angles A and B is 110 degrees"Result = TrueExplanation:
Recall that for any triangle, the three interior or inside angles always add to 180 degrees. In short: A+B+C = 180. If C = 70, then A+B = 180-C leads to A+B = 180-70 and A+B = 110. This process can be reversed.
========================================================
Part C
Converse = "If two lines are not parallel, then alternate interior angles k and s are not equal"Result = TrueExplanation:
For more information, check out the converse of the alternate interior angles theorem. The regular version of the theorem is "If two lines are parallel, then the alternate interior angles are congruent".
The converse of this theorem flips things to say: "If alternate interior angles are congruent, then the lines are parallel".
========================================================
Part D
Converse = "If John loses his money, then he throws coins in the fountain"Result = FalseExplanation:
Throwing coins in a fountain is one way to lose money, but there are other ways. He could drop a coin somewhere, or leave the coin somewhere he forgot.
In other words, just because he lost his money does not mean he threw a coin in the fountain.
Given that a = 10 cm and b = 13 cm, work out the height of the triangle.
Answers
The Pythagorean theorem is also known as the Pythagoras' theorem. The height of the triangle is 12cm.
What is Pythagoras theorem?The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between the three sides of a right triangle in Euclidean geometry. The size of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides, according to this rule.
Given a=10cm and b=13cm, therefore, the height of the triangle can be found using the Pythagoras theorem, therefore,
AB² = AD² + BD²
13² = AD² + 5²
169 = AD² + 25
AD = 12cm
Hence, the height of the triangle is 12cm.

Answer:
Slope = - 1/3
Step-by-step explanation:
Choose the point on the right and move upwards. How many times did you move upwards until you were at the same level as the point on the left? You moved once, which means your rise is 1.
Now from the point where you are at now, move right or left depending on where the point is. In this case, it's on the left which means our run will be negative. Now move left until you reach that point on the left. How many times did you move left? You moved three times, which means your run is 3.
Rise/Run = -1/3
Slope = Rise/Run
Slope: - 1/3

Let the measure of the supplementary angle be x.
The other angle will be: x + 20.
(x + 20) + x = 180
x + 20 + x = 180
2x + 20 = 180

What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
The nature of the relationship between the variables that makes up a function, such as y = sinx and y = x +6, defines the function.
Given the function,
y = 2(x² - 1)
If we increase the value of x to positive then the denominator x² - 1 will go to increase and thus y will decrease.
If we increase the value of x in negative then denominator x² - 1 will go to increase and thus y will decrease.
Therefore it is decreasing for all values in the domain.
Now,
Lim at x tends to ∞ of function is 2/∞ = 0 so y = 0 means there is a horizontal asymptote along the x-axis.
Hence "The given function y = 2(x² - 1) is decreasing for all values in the domain and it has a horizontal asymptote along the x-axis".
