Consider this sequence of transformations performed on shape I: a dilation by a scale factor of 2, followed by a reflection across the x-axis, and then a translation left 1 unit. Does the sequence prove that shapes I and IV are similar? Explain your answer.
Answer:
The sequence does map shape I onto shape IV. So, the sequence of transformations proves the two shapes are similar.
Step-by-step explanation:
To check whether the sequence proves that shape I is similar to shape IV, check whether the given sequence of transformations maps shape I onto shape IV.
1. Dilate shape I by a scale factor of 2.
2. Then, reflect the dilated shape across the x-axis.
3. Finally, translate the reflected shape 1 unit left.

if 1m is 100cm, then 250cm equivalent of 2.5m
if 1kg is 1.00g then 3kg is 2.500g
Answer:
I Kg = 1000 g
3 Kg = 3000 Kg
Step-by-step explanation:
Kg - Hg - Dag - g
1 Kg - 10 Hg - 100 Dag - 1000 g
So, 1 Kg = 1000 g
3 Kg = 3(1000)g = 3000 g

What key features does the factored form of quadratic function reveal
Answer:
Different key aspects of the graph are revealed by each form. From the vertex form, you can easily determine the vertex, (3, −4). From the factored form, you can easily determine the x-intercepts, 1 and 5. In standard form, the y-intercept is clearly 5.

Factor form of a quadratic function.
Factoring quadratics is a way of expressing the quadratic function:
ax2 + bx + c = 0
as a product of its factors as:
(x - k) (x - h),
where h, k are the roots of the quadratic function.
Thus,

I have the answers already but I really don't understand so I'm primarily in this for the explanation and work please!
Thank you <3
Answer:
h(g(f(x))) = -8x² - 40x - 50Step-by-step explanation:
Given:
f(x) = 2x + 5 g(x) = x²h(x) = -2xTo find h(g(f(x))) first find g(f(x)), substitute x with f(x):
g(f(x)) = g(2x + 5)Since g(x) = x², the value of g(2x + 5) is:
g(f(x)) = (2x + 5)²Now, the next step:
h(g(f(x))) = h((2x + 5)²) = -2(2x + 5)² = -8x² - 40x - 50Which unit would you use to measure the weight of a cell phone?

Answer:
add all the rest of the angles, and then subtract the sum from 1080, and that's your ans mate
Answer:
147
Step-by-step explanation:
If you add up all the angles you have, you get 933. Since an octagon has 1080 degree angles the last angle must be added to 933 to make it equal to 1080. If you subtract 933 from 1080, you get the remaining angle 147.

Solve for x Enter your answer, as one inequality,in the box
Answer:
x= (1,8)
Step-by-step explanation:
Answer:
Step-by-step explanation:
-3≤ 6x - 9 Add 9 to both sides
-3 + 9 ≤ 6x Combine left
6 ≤ 6x Divide by 6
6/6 ≤ 6x/6
1 ≤ x
6x - 9 < 39 Add 9 to both sides
6x < 39 + 9 Combine
6x < 48 Divide by 6
6x/6 < 48/6
x < 8
So the inequality is
1 ≤ x < 8
I think that is what you want. You have to express it as a combined inequality.

In the function above n is a constant if f(9)=4 what is the value of f(-3)
Answer:
This equation is in y=mx + b form. Just plug in the point to get N, which is also B.
Whatever is in f(x) is your x. So x = 9; This means...
4 = 2/3(9) + n
Solving for n gets you -2.
Now we plug in -3 and also substitute N now that we solved for it.
f(-3) = 2/3(-3) - 2
f(-3) = -4

We know that, Two angles are said to be complementary, if the sum of their measures is 90°.
According to the Question,
⇒ ∠ABD + ∠DBC = 90°
⇒ (2x + 30)° + (3x + 20)° = 90°
⇒ 2x + 30° + 3x + 20° = 90°
⇒ 5x + 50° = 90°
⇒ 5x = 90° - 50°
⇒ 5x = 40°
⇒ x = 40°/5
⇒ x = 8
So, the measure of each angle will be,
⇒ ∠ABD = (2x + 30)°
= 2 × 8 + 30°
= 16 + 30°
= 46°
⇒ ∠DBC = (3x + 20)°
= 3 × 8 + 30°
= 24 + 30°
= 54° ▄▄▄▄▄▄▄▄▄▄▄▄▄▄2.72135… rational or irrational

X=
S(-4, -6) and T(-7, -3); Find R.
Answer:
(13,-6)
Step-by-step explanation:
The midpoint is the exact halfway point, so all you need to do is find the distance between those two points and apply it again.
First find the x coordinate. The distance from -9 to 2 is 11. So you add 11 to 2, and you get 13, which is your x coordinate.
Then do the same thing with the y coordinate. And you get -6.
Your endpoint is (13,-6)

Multiply it by 3 = 3*x = 3x
Now add 4 to it: 3x + 4
Equation:
3x +4 = 22
b)
3x + 4 = 22
Subtract 4 from both sides
3x + 4 -4 = 22 - 4
3x = 18
Divide both sides by 3
3x/3 = 18/3
x = 6
Answer:
Below in bold.
Step-by-step explanation:
The equation is
3x + 4 = 22
3x = 22 - 4 = 18
x = 18/3
x = 6.
