Answer:
1. To dilate something in the coordinate plane, multiply each coordinate by the scale factor. This is called mapping. For any dilation the mapping will be \begin{align*}(x, y) \rightarrow (kx, ky)\end{align*}. In this Concept, the center of dilation will always be the origin, unless otherwise stated.
2. When using State Plane coordinates the scale factors, also known as the K factors, are ratios that can be used as multipliers to convert ellipsoidal lengths, also known as geodetic distances, to lengths on the map projection surface, also known as grid distances, and vice versa.
3.Similar figures have the same shape (but not necessarily the same size) and the following properties: Corresponding sides are proportional. That is, the ratios of the corresponding sides are equal. Corresponding angles are equal.

what is the distance, in units, between the y-intercept of f(x) = x^2 +7x - 18 and the y-intercept of the linear function that passes through the points shown on the table below
x g(x)
-5 2
10 11
25 20
60 41
Answer:
13
Step-by-step explanation:
f(x) = x² +7x - 18
y interception: x=0 y = -18 (0 , -18)
line g(x): --- the data of (60,47) to make a linear function
y = mx + b
m = (11-2) / (10 - -5) = 9/15 = 0.6
b = mx - y = 0.6 * (-5) - 2 = - 5 ... y intercept: (0 , -5)
distance between 2 y intercept: 18-5 = 13
y = 0.6x - 5
Answer:
23
Step-by-step explanation:
f(x) (y intercept ) = -18
g(x) (y intercept) = 5
difference so f(x)-g(x)
-18-5 = -23
the answer cannot be negative

151 3/16 divided by 10 1/4
Answer: 59/4 or 14 3/4
Step-by-step explanation:
151 3 /16 ÷ 10 1 /4
2419 /16 ÷ 41 /4
2419/16 × 4/41
2419 × 4 /16 × 41
9676 /656
Divide both sides by 164
9676 ÷ 164 / 656 ÷ 164
59 /4 = 14 3 /4
In the diagram below, the three lines intersect in the same point, forming six numbered angles.
For the given figure of intersecting lines the expression holds is m∠1 + m∠3 + m∠5 = 180°. Option D is correct.
Given that, A figure of the intersecting lines is given where 3 lines intersect at the same point.
What is the angle?The angle can be defined as one line inclined over another line.
What is a Line?A line can be defined by the shortest distance between two points is called a line.
Here,
From the figure
∠1 = ∠4
∠2 = ∠5
So,
∠6 = ∠3
Now, from the option, the property hold is m∠1 + m∠3 + m∠5 = 180°. because m∠1 + m∠6 + m∠5 = 180°, or ∠6 = ∠3.
Thus, for the given figure of intersecting lines the expression holds is m∠1 + m∠3 + m∠5 = 180°. Option D is correct.

The pizza shop down the street offers a special of a large pizza with 3 toppings. The choices of toppings
are pepperoni, sausage, ham, pineapple, cheese, onions, green peppers, hot peppers, mushrooms, and
anchovies.
How many ways can you arrange 3 toppings out of 10 toppings on a pizza?
Answer:
120 ways
Step-by-step explanation:
To solve this question, we would be using the law of combination.
In combination, we say that
nCr = n! / (n - r)! r!, where both r and n are integers.
Now, referring to question, we are asked how many ways we can arrange 3 toppings out of 10. This means we're looking for 10C3. Applying the earlier laid out formula, we have
10C3 = 10! / (10 - 3)! 3!
10C3 = 10! / 7! 3!
10C3 = 3628800 / 5040 * 6
10C3 = 3628800 / 30240
10C3 = 120
Therefore, the toppings can be arranged in 120 ways.

Congruent triangle
Answer:
x = 3
Step-by-step explanation:
exterior angle of a triangle is equal to the sum of the measures of the two remote interior angles
97 + x = 64 + 27
x = 97 - 64 - 27 = 6
Answer: x=-6
you know that the interior angles of a triangle equal 180°. so lets find the remaining angle measure
64 + 27 = 91
180 - 91 = 89
so 89 is the third interior angle of the triangle. now let's find the exterior angle.
you know that the extended angle is supplementary; which means it will equal 180° as well. so lets add the third interior angle we just found and let's add it to the unknown expression:
89 + 97 + x = 180
186 + x = 180
-186 -186
x = -6
now it might seem wrong because x is negative and it feels like it should be positive. but let's check our answer.
64+27+89 does equal 180
and 97+(-6)+89 does equal 180

3x−y=1?
Step-by-step explanation:
We wish to express 3x - y = 1
in slope-intercept form.
3x - y = 1
=> y = 3x - 1
Slope of line = 3, therefore
Slope of parallel line is also 3.
We have y = 3x + c.
When x = 1, y = 7.
=> (7) = 3(1) + c, c = 4
Hence the answer is y = 3x + 4.

If the perimeter is 374 units, find the value of x and the area of the triangle.
The value of x is
The area is
square units.
Answer:
x = 17
Area = 10,362units²
Step-by-step explanation
Given the sides of the triangle
S1 = 9x+4
s2 = 8x-4
S3 = 4x+17
Perimeter of the triangle is the sum of all the sides
P = S1+S2+S3
374 = 9x+4+8x-4+4x+17
374 = 21x+17
21x = 374-17
21x = 357
x = 357/21
x = 17
Hence the value of x is 17
Area of the triangle is 1/2bh
A = 1/2bh
b is the base
h is the height
Let the base be 9x + 4 and height be 8x-4
b = 9x+4
b = 9(17)+4
b = 153+4
b = 157units
h = 8x-4
h =8(17)-4
h = 136-4
h = 132
Area = 1/2 * 157 * 132
Area = 157*66
Area = 10,362units²
