1.dilate by 3/5 : (20,10)
2.translate (x+5,y-6): (7.8)
3.reflx across th x-axis: (4,7)
4.rotate 270 degrees: (7,9)
Answer:
a) )12,6)
b) (12,2)
c) (4,-7)
d) (9,-7)
Step-by-step explanation:
a) Dilation
When we dilate, we multiply the given scale factor by each of the coordinates
We have this as follows;
(20 * 3/5, 10 * 3/5) = (12, 6)
2. Here, we will add 5 to the x-axis value and subtract 6 from the y-axis value
We have this as;
(7+ 5, 8-6) = (12,2)
3. By reflecting across the x-axis
we have (x,y) changing to (x,-y)
so we have ;
(4,7) becomes (4,-7)
4. Rotation by 270 degrees (7,9)
If clockwise;
(x,y) becomes (y,-x)
so we have
(7,9) becoming (9,-7)

Find m∠ J
Use a calculator. Enter only a number
Answer:
26 degrees.
Step-by-step explanation:
We are given
Side KL length which is 46. (let call that side j).Side JL length which is 93( let call that side k).Angle L=90.We are trying to find angle measure of j.
Since we are given a side opposite of our angle we are trying to find and a side adjacent to the angle we are trying to find we are going to use tan ratio.
[tex] \tan(x) = \frac{opp}{adj} [/tex]
[tex] \tan(x) = \frac{46}{93} [/tex]
since we are trying to find the angle measure apply inverse trig function
[tex] \tan {}^{ - 1} ( \frac{opp}{adj} ) [/tex]
Plug 46 for opp and 93 for adj.
[tex] \tan {}^{ - 1} ( \frac{46}{93} ) [/tex]
which is about 26 degrees.

The sum of the first 75 terms of the sequence is -5.068*10^34
Given the following geometric sequence
[tex]a_1 = \frac{-1}{3} \\a_i = a_{i-1}*(-3)[/tex]
The sum of the nth term of the GP is expressed as;
[tex]S_n = \frac{a(1-r^n)}{1-r}[/tex]
a = -1/3
n = 75
r = a₂/a₁
a₂ = -3a₁
a₂ = -3(-1/3)
a2 = 1
r = 1/(-1/3)
r = -3
Substitute the given values in the formula;
[tex]S_n = \frac{-1/3(1-3^{75})}{1-(-3)}\\S_{75} = \frac{-1/3(3^{75}-1)}{1+3} \\S_{75} = \frac{-1/3(6.082 \times 10^{35}-1)}{4}\\S_{75} = \frac{-1/3(6.082 \times 10^{35})}{4}\\S_{75} = -0.5068 \times 10^{35}\\S_{75} = -5.068 \times 10^{34}\\[/tex]
Hence the sum of the first 75 terms is -5.068*10^34

what is the value of x? given angle is 68 degrees?
Answer:
68°
Step-by-step explanation:
x + 56 + 56 = 180
x = 180 - 56 - 56
x = 180 - 112
x = 68°
The value of x for the triangle with angles a,b, and x is 68°.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
We will assume that there is a triangle with three angles:
a, b, and x.
The sum of the three angles is 180°.
Now,
a + b + x = 180
a = b = 56°
x = 180 - (56 + 56)
x = 180 - 112
x = 68°
Thus,
The value of x is 68°.

Answer:
-3x+3=5x+19
5x+3x=3-19
8x=-16
x=-2
Hope this helps <3
Answer:
x = -2
Step-by-step explanation:
we know,
y is common in both
so ,
-3x + 3 = 5x + 19
-3x +3-19=5x
-3x - 16 = 5x
-3x -5x = 16
-8x = 16
x = 16 / -8
x= -16/8
x= -2
also if you put value of x = -2 in both the expression you will get y = 9
