If triangle DEF is dilated by a scale factor of 1/2 with center of dilation at the origin
(0,0), what is the x-coordinate of E'?
Please help 20 points
Answers
Answer:
(4,2)
Step-by-step explanation:
I am not able to see your screen well but these are the points that I saw in the beginning for E. 8,4. Your x value is either left or right and your y value is up and down. I saw 8 units right and 4 u it's up. Now your scale factor is 1/2. Remember if the scale factor is less than one the figure reduces. Our rule for dilations is (x,y) → (kx,ky). The scale factor is represented by K. Since your scale factor is 1/2 we know our triangle will reduce. Let's plug 1/2 in our x and y valued.
So E is (8,4). 8*1/2 is 4 and 4* 1/2 is 2. Are new points are E' (4,2).

Answers
1.) -6x + y = 4
Move variable x over to the other side by adding 6x.
y = 6x + 4
2.) -y - 2x = 4
Move variable x over to the other side by adding 2x.
-y = 2x + 4
Divide the whole thing by -1 because y needs to be positive and alone.
y = -2x - 4

what is £120 by 40% Decreased
Answers
Explanation:
Decrease: (1-40%)
120 x (1-40%)
= 120 x 60/100
= 120 x 3/5
= 360/5
= £72
Answer:
£72
Step-by-step explanation:
100% - 40 = 60%
60/100 = 0.6
0.6 * £120 = £72
40/100 = 0.4
0.4 * £120 = £48
To check:
£72 + £48 = £120

Answer:
x = 20
Step-by-step explanation:
Let’s think about it this way ( i’m gonna make this as easy as possible! )
So, x is the variable, which it represents the height of the tree right? so you’re gonna want to take the shadow of the alien, and think “well can 8 make 32? and if so how many times?” which would be 8y = 32. and yes you can. so let’s think about that. how many times does it take for 8 to get to 32?
8, 16, 24, 32
so it takes 4 times. then you think “ well if 8x4 got the shadow length, 5x4 must get the tree height” which is correct.
you’ll take 5 x 4 which is 20, and you will put that down as the heigh of the tree, or think 20ft.
so x = 20.

Answer:

Step-by-step explanation:
Polynomial long division is done the way any long division is done. Find a "partial quotient", subtract from the dividend the product of that partial quotient and the divisor. The result is a new dividend. Repeat until the degree of the dividend is less than that of the divisor.
__
In the attached, the "Hints" show you how the partial quotient is found, and they show you how the product of the partial quotient and divisor is found.
The partial quotient term is simply the ratio of the highest degree terms of dividend and divisor. (Unlike numerical long division, there is no guessing.)
__
The remainder is the dividend of lower degree than the divisor. As in numerical long division, the full quotient expresses the remainder over the divisor.
For example, 5 ÷ 3 = 1 r 2 = 1 + 2/3.
Your full quotient is (n+5) +1/(n-6).
Function 1 is defined by the equation p= --3/2r - 5. function 2 is defined by the following table. Which function has a greater y-intercept. A: Function 1 B: Function 2 C: The functions have the same y-intercept.
Answers
The y-intercept of function 1 is -5.
The y-intercept of function 2 is -5.
Option C is the correct answer.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
Consider the function to be in the form of p = mr + c
Where x is the y-intercept.
Function 1.
p = (-3/2)r - 5 _______(1)
y-intercept = -5
Function 2.
Let p = mr + c
Take two pairs from the table.
(0, -5) and (1, -6.5)
m = (-6.5 + 5) / (1 - 0) = -1.5
(0, -5) = (r, p)
-5 = -1.5 x 0 + c
c = -5
Now,
p = -5x - 5 ______(2)
y-intercept = -5
From (1 ) and (2)
Both have the same y-intercept.
Thus,
Function 1 and Function 2 have the same y-intercept.

The length of f of the triangle is f = 11.7 cm
What is Law of Cosines?The Law of Cosines is a mathematical formula used to find an unknown side or angle of a triangle, given the lengths of the other two sides and the angle opposite the unknown side. It is also known as the Cosine Rule.
The Law of Cosines states that for any triangle with sides a, b, and c and angle C opposite side c, the following equation is true:
c² = a² + b² - 2ab cos(C)
where cos(C) is the cosine of angle C. This formula can be rearranged to solve for any of the variables, depending on which values are known.
Given data ,
Let the triangle be represented as ΔEFG
And , the measures of the sides of the triangle are
g = 4.3 cm
e = 9.1 cm
And , measure of angle ∠F = 116°
where c² = a² + b² - 2ab cos(C)
On simplifying , we get
a² = c² - b² + 2abcos ( C )
78.26 ( cos 116° ) - 4.3² - 9.1² = f²
f² = 135.7344
Taking square roots on both sides , we get
f = 11.7 cm
Hence , the length is f = 11.7 cm
