Answer:
D. If I do not do my homework, then it will not snow.
Explanation:
An inverse of anything is the contrary or opposite of the given statement or idea or anything. And in a way, it is the same as the antonym, opposite or contradictory factor of the given point.
The given sentence/ proposition is-
if I do my homework, then it will snow.
In this sentence, the hypothesis of the homework getting done concludes that it will snow. So, for the inverse of this proposition, the positive nature of the sentence will be turned into a negative one.
Thus, the correct answer will be such that if the homework is not done, then it will also not snow. So, the correct answer is option D.
Answer: it’s D
Step-by-step explanation:
Alice earns £450 in wages per month. She pays £200 in rent per month. Next month, • her wages will increase by 2% • her rent will increase by 5% She says “The increase in my wages will pay for the increase in my rent” Is she correct? You must show your working.
Step-by-step explanation:
Wages
£450
450 x 1.02 = 459
Rent
£200
200 x 1.05 = 210
wages increases by £9
rent increases by £10
No the increase in her wages will not fully pay for the increase in the rent

Answer:
Two polygons are similar with factor k.
=> The ratio between the area of two polygons: r = k^2
=> Here, the area of polygon B is larger than polygon A: 5^2 = 25 times
Hope this helps!
:)
Answer:
Area of polygon B is larger than the area of Polygon A by 25 times.
Step-by-step explanation:
The simplest way of finding this would be to draw a rough image of polygon A and B.
Let's say you drew Polygon A and B as rectangles. Since the scale factor is 5, the dimensions of the sides of polygon B would be 5 times as that of the dimensions of polygon A.
if you label the dimensions of Polygon A as length 2cm and width as 1cm, its area would be 2 square centimetres.
now keeping the scale factor of 5 in mind, multiply the length and the width by 5. you will get the length of polygon B as 10cm and width as 5cm. the area of polygon B becomes 50 square centimetres.
once you have done this, you will realise that the area of polygon B is 25 times the area of polygon A.

the transformation is a rotation
true or false
Answer:
FALSE
Step-by-step explanation:
The transformation is a reflection across the line x=1.
In order from shortest to longest, the sides of the left triangle are in counterclockwise order. In the right triangle, they are in clockwise order. This indicates a reflection. A rotation does not change the (CW/CCW) orientation of the triangle.
It is False that the transformation is a rotation.
A triangle has the coordinates
A(4, -1), B(3, -3), and C(0, 2).
Reflect the triangle over the y-axis and find the coordinates of its image.
A(4, -1) - AU
B(3,-3) - BO
C(0, 2) - C'e
-od
Answer:
coordinates of its image
A' = ( -4, -1)
B' =( -3, -3)
C' = ( 0, 2)
Step-by-step explanation:
Reflect in y-axis means mirror it's points in the y -axis.
This means that the x coordinate of each point, changes only. Any mirrored point in the y-axis, will change only, by multiplying the x-coordinate by -1.
(Remember, zero multiplied by -1 remains 0).
Given are these points A, B, and C.
A = (4, -1)
B = (3,-3)
C = (0, 2)
After mirroring in the y- axis you get:
A' = ( -4, -1)
B' =( -3, -3)
C' = ( 0, 2)
Originally the dimensions of a rectangle were 15cm by 20cm. When both dimensions were decreased by the same amount, the area of the rectangle is half the area of the original rectangle. Find the dimensions of the new rectangle.
Answer:
Step-by-step explanation:
We can write an equation to represent this problem.
(15 + w)(20 + w) = 1/2 (15)(20)
Foil out the left side of the equation.
300 + 35w + w^2 = 150
Subtract 150 from both sides.
w^2 + 35w + 150 (I rearranged it to be in the form that is most efficient)
Now solve for variable w using the quadratic equation (look up the formula if necessary)
[-35 +_ (square root of the value of 1225-600)] / 2
[-35 +_ (SqRt of 625)] /2
(-35 +_ 25) /2
= -30, -5

Which statement is true about the y-intercept of a quadratic function?
A.
A quadratic function can only have one y-intercept.
B.
A quadratic function can have up to two y-intercepts.
C.
The y-intercept is also called a zero of the function.
D.
The y-intercept is located at the point where the value of y is 0.
Reset
Next
Answer:
A.
Step-by-step explanation:
A quadratic function may only intercept the y-axis once. This is because the definition of a y-intercept tells us that it is the point where x = 0. If there are multiple points where x = 0, then the expression cannot be a function. As such, a quadratic function can only have one.
Choice B contradicts the previous statement.
Choice C is wrong because the x-intercept is the zero of the function. This is because at a given x-coordinate that touches the x-axis, the y-coordinate will be 'zero'.
Choice D is wrong because the y-intercept is where x = 0.

find the coordinates of the vertices of a quadrilateral after reflection across the parallel lines; first across the x-axis and then across the line y= 1.
R(0,1), S(3,0), T(5,-4), Q(1,-3)
Answer:
R'(0, 3), S'(3, 2), T'(5, -2), Q'(1, -1)
Step-by-step explanation:
The first reflection gives you the transformation ...
(x, y) ⇒ (x, -y)
The second reflection gives you the transformation ...
(x, y) ⇒ (x, 2 -y)
Applying the second transformation to the result of the first gives the overall transformation ...
(x, y) ⇒ (x, 2 -(-y)) = (x, 2+y)
That is, the double reflection is equivalent to a translation upward of 2 units. So, we add 2 to each y-value:
R'(0, 3), S'(3, 2), T'(5, -2), Q'(1, -1)

The length of a rectangle is 4 inches more than its width and its perimeter is 34 inches find the length and width of the rectangle if w= the width of the rectangle then the length equals
Answer:
The length and width of the rectangle are 10.5 in and 6.5 in respectively.
Step-by-step explanation:
P = 2L + 2W
P (perimeter of the rectangle) = 34 in
L (length of the rectangle) = 4 in + W (width of the rectangle)
Therefore, L = 4 + W
P = 2L + 2W
34 = 2(4 + W) + 2W
34 = 8 + 2W + 2W
34 - 8 = 4W
26 = 4W
W = 26/4 = 6.5 in
L = 4 + W = 4 + 6.5 = 10.5 in
L = 10.5 in
W = 6.5 in

find the coordinates of F' after reflection across the line
x = -1 and then across the line
y = -1. Answer in form (a,b). Part 6a
=============================================================
Explanation:
Focus on point F only. Ignore the other points.
Point F is at (-5, -5).
The x coordinate of this point is x = -5
The horizontal distance from x = -5 to the reflection line x = -1 is 4 units. We move 4 units to the right going from x = -5 to x = -1. Move another 4 units to the right to land on x = 3
Point F = (-5, -5) reflects over x = -1 to land on point G = (3, -5) as shown in the diagram below.
Then going from point G to H has us move upward 4 units up to land on the purple line y = -1, then another 4 units up to finally arrive at point H = (3,3). This is also the location of F'.

write the equation of the line passing through the given point T (-6,2) and is parallel to the line
y=2/3x
Answer:
y = [tex]\frac{2}{3}[/tex] x + 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{2}{3}[/tex] x ← is in slope- intercept form
with slope m = [tex]\frac{2}{3}[/tex] and c = 0
Parallel lines have equal slopes , thus
y = [tex]\frac{2}{3}[/tex] x + c ← is the partial equation
To find c substitute (- 6, 2) into the partial equation
2 = - 4 + c ⇒ c = 2 + 4 = 6
y = [tex]\frac{2}{3}[/tex] x + 6 ← equation of parallel line
