Write an equation for each translation of y= |x|.
13 units down
A. y = | x | + 13
B. y – 13 = | x |
C. y = | x | – 13
D. y = | –13x |
Answer:
C. y = | x | – 13
Step-by-step explanation:
y = | x | – 13
Answer:
y = |x| -13
Step-by-step explanation:
recall for any function y = f(x), to translate the function vertically by any value "a", we simply have to add "a" to f(x).
If a is positive, then the graph is translated in the positive y-direction (i.e upwards), if a is negative, then the graph is translated in the negative y-direction (i.e downwards)
In our case , the graph is translated vertically by 13 units (i.e a = 13) and it is to be translated downwards (i.e negative)
hence we add a= -13 to the original function.
y = f(x) + (-13)
y = |x| + (-13)
y = |x| -13

What is the value of 84−−√12?
Enter your answer as a whole number, like this: 42
Answer:the answer is 2 Step-by-step explanation: i took the test
The value of the given expression is 87.46.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The given expression will be solved as below:-
E = 84-( -√12)
Two negative signs cancel out into a positive sign
E =84 + √12
84 plus the square root of 12. The square root of 12 is 3.5 or 3.46.
E = 84 + 3.46
E = 87.46
Therefore, the value of the given expression is 87.46.

Triangles P and Q are similar. Find the lengths of the sides
Answers:
AB = 9YZ = 15==========================================================
Explanation:
In triangle P, aka triangle ABC, we have the color coded angles:
angle A = blueangle B = purpleangle C = redFor triangle Q, aka triangle XYZ, we have:
angle X = blueangle Y = purpleangle Z = redThe colors must pair up to match together. The order is important. That order being "blue, purple, red".
Because of this, we have the three pairs of congruent angles:
angle A = angle X (blue)angle B = angle Y (purple)angle C = angle Z (red)Furthermore, that extends to having these pair of corresponding sides that match up together:
side AB and side XY (blue and purple angles)side BC and side YZ (purple and red angles)side AC and side XZ (blue and red angles)-----------------------
Side AC = 7 involves the blue and red angles. The same applies to XZ = 21.
The jump from 7 to 21 is "times 3", which tells us the scale factor. The triangle XYZ has side lengths 3 times longer compared to triangle ABC.
We'll use this scale factor to determine the missing sides of each triangle.
-----------------------
Side BC = 5 involves the purple and red angles. For the other triangle, side ZY involves those same color angles. Going from BC = 5 to ZY = unknown will involve the "times 3" operation. So we have,
ZY = 3*BC = 3*5 = 15
-------------------------
Side AB = unknown pairs up with side XY = 27 of the other triangle. Each side mentioned involves the blue and purple angles.
Instead of multiplying, we'll do the opposite: we divide 27 by 3 to get the side of AB.
This is because:
XY = 3*AB
AB = XY/3
AB = 27/3
AB = 9

A line goes through the point (2,5) and is parallel to the line above, answer the
following:
a, what is the equation of the line that goes through these points in Slope-i
Intercept Form.
b. What is the x-intercept?
c. What is the y-intercept
Answer:
Step-by-step explanation:
a, what is the equation of the line that goes through these points in Slope-intercept Form?
If two lines are parallel, their slopes are equal. Thus the new line has the same slope as does the old one: m = -3. We adapt the slope-intercept form y = mx + b to 5 = (-3)(2) + b and find that b = -11. Then the desired equation is y = -3x - 11. This is in slope-intercept form.
b. What is the x-intercept? Start with the above y = -3x - 11. Set y = 0 and solve the result, 0 = -3x - 11, for x: x = -11/3. Then the x-intercept is (-11/3, 0); this is the point at which the graph crosses the x-axis.
c. What is the y-intercept: Set x = 0 in the above equation. We get y = -11.
The y-intercept is thus (0, -11).
A school was taking a field trip. The principal wanted 2 teachers for every 45 students. If 270 students will be attending the trip how many teachers must chaperone
Answer:
The answer is 6.
Step-by-step explanation:
If there are 270 students going on the trip and there would be a teacher for every 45 students you would have to divide.
You would divide 270 ÷ 45 = 6.
The required number of teachers for the trip is 12.
Given that,
A school was taking a field trip. The principal wanted 2 teachers for every 45 students. If 270 students will be attending the trip how many teachers must chaperone is to be determined.
Proportionality is defined as between two or more groups of values, and how these values are related to each other in the sense that are they directly proportional or inversely proportional to each other.
Let the number of teachers is x and the number of students is y, which are directly proportional to each other
y ∝ x
y = km
where k is the constant proportionality.
at y = 45 x = 2
45 = K * 2
K = 45 / 2
Now,
y = 45/2 x
Now for y =270
270 = 45 / 2 x
x = 270 * 2 / 45
x = 12
Thus, the required number of teachers for the trip is 12.

Solve with substitution show steps please.
9514 1404 393
Answer:
(x, y) = (4, 1)
Step-by-step explanation:
Step 1. Look for an equation that has a coefficient of 1 or -1 for one of the variables. Here, that is the first equation, which has a y-coefficient of -1.
Step 2. If you found such an equation, solve for the variable.
y = 2x -7
Step 3. Use that expression for the variable to substitute into the other equation.
3x -2(2x -7) = 10
Step 4. Solve the resulting equation in the usual way.
3x -4x +14 = 10 . . . . . eliminate parentheses
-x +14 = 10 . . . . . . . collect terms
4 = x . . . . . . . . . separate variable terms and constant terms. Here, we added x-10 to both sides.
If the variable has a coefficient that is not 1, divide both sides by that coefficient.
Now, you can use this value in the expression for y that we found above.
y = 2(4) -7 = 1
The solution is (x, y) = (4, 1).

Answer:
8x + 6 = 2 * (5x - 2)
x = 5
OP = 46
Step-by-step explanation:
The Triangle Midsegment Theorem
A midsegment connecting two sides of a triangle is parallel to the third side and is half as long.
So, PO = 2 * SQ
8x + 6 = 2 * (5x - 2)
8x + 6 = 10x - 4
6 + 4 = 10x - 8x
10 = 2x
x = 5
OP = 8x + 6
= 8 * 5 + 6
= 40 + 6

What is the distance between (-8,2)and (6,2)?
Please help me
Answer:
The distance is 4 units.
Step-by-step explanation:
Let the distance between the two points (x₁, y₁) and (x₂, y₂) is
d = √(x₂ - x₁)² + (y₂ - y₁)²
Here, the given points are (2,8) and (6,8), therefore,
x₁ = 2, x₂ = 6,
y₁ = 8, y₂ = 8
d = √(x₂ - x₁)² + (y₂ - y₁)²
d = √(6 - 2)² + (8 - 8)²
d = √(4)² + (0)²
d = √16
d = 4
Thus, The distance is 4 units.
