ILL MARK U BRAINLIEST IF U DO THIS AND GET IT RIGHT
Answer:
Step-by-step explanation:
1.
The x's and y's will shift to the right and upward. This will make the shape larger because we are multiplying each point (x, y) by 2 [2(x, y)]. The new shape is similar since it is practically the same exact figure with a different scale. Furthermore, the angle measurements are congruent.
2. This will shift the x's and the y's upward and to the right making the shape larger although the shape will be stretched and will not be similar in terms of angle measures and other factors.
3. This will make the figure larger although the angle measurements will not be preserved and a new shape will form. This will not be similar from the original one since it will be stretched and the angles measurements are not congruent..

In the rhombus, the measure of angle 1 = 18x, the measure of angle 2 = x + y, and the measure of angle 3 = 30z. Find the value of x + y + z. The diagram is not drawn to scale.
Answer:
A. 93
Step-by-step explanation:
Each angle is 90 degrees.
18x = 90
x=5
x + y = 90
5 + y = 90
y = 85
30z = 90
z = 3
5 + 85 + 3 = 93
Tyler is conducting a science experiment. He is observing the effects of
low temperatures on bacteria. He cools one sample to -55˚C and
another to -80˚C. What is the difference between the two
temperatures?
Answer:
Your answer is -25
Step-by-step explanation:
First, you figure out what to do for the equation.
In this case we you would subtract because it says "what is the difference" which means to subtract.
So -55 subtracted by -80 = -25

Kevin has a rectangular
swimming pools that is 12
feet by 16 feet. He wants
to put a rope diagonally
across the pool. How long
does the rope need to
be?
Answer:
20 feet long
Step-by-step explanation:
To solve this you need to use the Pythagorean theorum, [tex]a^2+b^2=c^2[/tex], where c is the length of rope needed and A and B are the side lengths. Think of it like a right triangle.
So, the equation is
[tex]12^2+16^2=c^2[/tex]
Which is then
[tex]144+256=c^2[/tex]
[tex]c^2=400[/tex]
And the possible values of c are 20 and -20.
From here we know the answer cannot be -20 because you cannot have a negatively long length of rope, so the answer must be 20 feet.
Answer:
20 feet
Step-by-step explanation:
Use Pythagoras's theorem.
[tex]A^{2}+B^{2} =C^{2} \\12^{2} +16^{2}= C^{2} \\400 = C^{2} \\\sqrt{400}= \sqrt{C^{2}\\\\[/tex]
20 = C

Sandra wrote p(x) = 30x + 5x2 in vertex form. Her work is below. 1. p(x) = 5x2 + 30x 2. p(x) = 5(x2 + 6x) 3. (six-halves) squared = 9; 4. p(x) = 5(x2 + 6x + 9) – 5(9) 5. p(x) = 5(x + 3)2 – 45 Describe Sandra’s function. What is the vertex of this function? Is it a maximum or a minimum? What is the axis of symmetry of this function?
Answer: 1st question• (-3, -45)
2nd question• x= -3
Step-by-step explanation:
just did it on edge
The vertex of the function p(x) = 30x^2 + 5x^2 is (-3,-45), and it is a minimum
The description of the functionThe function is given as:
p(x) = 30x^2 + 5x^2
The description of the function is that the function is a quadratic function
The vertex
From the question, we have:
p(x) = 5(x + 3)^2 – 45
A quadratic function represented as: p(x) = a(x - h)^2 + h has the vertex (h,k)
This means that the vertex is (-3,-45), and it is a minimum because a is positive i.e. a = 5
The axis of symmetryThis is the x-coordinate of the vertex.
Hence, the axis of symmetry is x = -3

Write the equation in slope intercept form
2x+y=6
Answer: the slope intercept form of 2x+y=6 is y=-2+6
Step-by-step explanation:
2x+y=6 (subtract 2x from both sides)
-2x -2x (the -2x and the 2x cancel leaving...)
y=-2x+6 →( y equals negative two x plus six)
5x - 2y = 26 y + 4 = x
We call a natural number "nice" if there are only even digits in its recording. How many "nice" four-digit numbers are there?
Answer:
I suppose that this refers to numbers like:
N = abcd
Where a, b, c and d are single digits.
We want to find the number of 4-digit numbers such that:
a, b, c and d are even numbers.
So let's count the number of options for each digit, where we impose that the possible digits must be even.
a: Here we have the options {2, 4, 6, 8} ( 0 is an even digit, but if we take a = 0, then this would be a 3 digit number) Then we have 4 options for a.
b: Here we have the options {0, 2, 4, 6, 8}. 5 options in total.
c: Here we have the options {0, 2, 4, 6, 8}. 5 options in total.
d: Here we have the options {0, 2, 4, 6, 8}. 5 options in total.
The total number of possible combinations will be equal to the product of the number of options for each selection.
C = 4*5*5*5 = 500
There are 500 "nice" numbers of 4-digits.

I need help with the equation inserted in the picture.
Answer:
x = 4
-4x+21 => 5
Step-by-step explanation:
The given triangle in the picture is isosceles triangle which means that two sides of the triangle are equal.
So,
[tex]Side\ 1: -4x+21\\Side\ 2: -4x+21\\Side\ 3: 6\\Perimeter = 16[/tex]
Now
Putting all the values in equation for perimeter
[tex]Side\ 1+Side\ 2+Side\ 3 = 16\\-4x+21 -4x+21 + 6 =16\\-8x +48 = 16\\-8x = 16-48\\-8x = -32\\\frac{-8x}{-8} = \frac{-32}{-8}\\x = 4[/tex]
Putting x = 4 in side 1
[tex]=-4(4)+21\\= -16+21\\=5[/tex]
Hence,
x = 4
-4x+21 => 5
Mason says you can find an equivalent ratio by adding the same number to both
quantities in a ratio. For example, 2:3 is equivalent to 3:4 because 2 + 1 = 3 and
3+1 = 4. Is Mason correct? Explain your thinking.
Answer:
No Mason is not correct you would use fractions and find a common denominator such as 12 and 2/3 would be 8/12 and 3/4 would be 9/12 therefore the two ratios are not equivelent
No, the statement is not correct.
What is ratio?Ratio is the comparison of two quantities which is obtained by dividing the first quantity by the other. If a and b are two quantities of the same kind and with the same units, such that b is not equal to 0, then the quotient a/b is called the ratio between a and b. Ratios are expressed using the symbol of the colon (:). This means that ratio a/b has no unit and it can be written as a : b
The example given here is not relevant.
This is because if 2:3 is added by 1/1
gives 3/4 or 3:4
but 3:4 cannot be more simplified.
So, let us make the equivalent denominator for both
2/3*4*4= 8/12
3/4*3/3=9/12
So, 2:3 ≠3:4

When plotting temperatures, it's important to remember positives and negatives
It's always a good idea to start by marking the halfway point as zero
Then, if the numbers are in the tens, make each increment an increasing value of ten/-ten in each direction.
If they're low, (in the ones digits) then just mark the numbers on the increments in the positive/negative directions

whats the equation for the in slope intercept form?
Answer: y = -4x + 5
Step-by-step explanation:
To write the equation in slope intercept form, we need to find the slope and the y intercept.
The y intercept is when the x coordinate is zero, and looking at the line we can say the y-intercept is 5 because when x is 0 y is 5
y intercept: (0,5)
Now find another point on the line to find the slope of the line .
(-2,13)
The slope is the difference between the y coordinates divided by the difference in the x coordinates.
(0,5) and (-2,13)
y coordinates: 5 - 13 = -8
x coordinates: 0 - (-2) = 2
Slope: -8/2 = -4
