please help and can someone explain what a integer is
w = -18
x = -10
y = -2
z = 10
x and z are opposite, x= -10, where as z = 10, Hence x times (-1) equals z.
An integer is a non-fractional number real number. It can be either negative or positive, it simply cannot be a fraction.
"w", "x", and "y" are negative, and hence less than zero.

We can notice the shapes have a parallel side. Actually we can see all corresponding sides are parallel after closer look.
This is the sign of 180° rotation. Same effect is obtained by double reflection: vertical and horizontal.
Any other reflection or combination with rotation or translation will change the angle to different so options B, C and D are excluded.
Correct options are A and E

By rounding to 1 significant figure, estimate
542.04 × 1.88
By rounding to 1 significant figure 542.04 × 1.88 equal to 1019.0352
is 1019.
What is rounding off of numbers?We round off numbers to make them easier to remember and it also keeps their value approximately to the place it has been rounded off.
To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.
Given we have to round off 542.04×1.88 = 1019.0352.
Now rounding off to one significant digit means we should have only one digit after the decimal place and the second digit after the decimal place is 3 which is less than 5.
∴ 1019.0352 rounded off to one significant digit is 1019.

Answer:
Area = 10
Step-by-step explanation:
Here is how to solve:
(x1y2+x2y3+x3y1-y1x2-y2x3-y3x1) / 2
In your case
A(2,2) is x1=2, y1=2
B(6,2) is x2=6, y2=2
C(6,7) is x3=6, y3=7
So
((2x2)+(6x7)+(6x2)-(2x6)-(2x6)-(7x2)) divided by 2 = 10
Area = 10

If P=(-3,4), find: Rx-axis (P)
Answer:
(-3,-4)
If it was on the y-axis it would be (3,4)
Step-by-step explanation:
Rx-axis (P) = (-3, -4)
What is reflection about x-axis?"When we reflect a point about x-axis then the x-coordinate remains the same, but the y-coordinate changes its symbol."
For given example,
we have been given a point P = (-3, 4)
We need to find Rx-axis (P)
That is we need to reflect given point about x-axis.
We know, when we reflect a point about x-axis then the x-coordinate remains the same, but the y-coordinate changes its symbol.
So, the reflected point would be (-3, -4)
Therefore, Rx-axis (P) = (-3, -4)

triple the difference of six less than a number (rewrite)
Answer:
3(6-x)
Step-by-step explanation:
The expression "Triple the difference of six less than a number" can be represented as 3 * (x - 6), where x represents the number.
To mathematically represent "Triple the difference of six less than a number," we can use the following expression:
3 * (x - 6)
Here, x represents the number, and the expression calculates the difference between the number and six, which is then multiplied by three.

Prove that the triangle with vertices A(0,1), B(3,3), and C(3,-1) is an isosceles triangle. Select the two sides that are congruent.
Answer:
AB and AC are congruent
Step-by-step explanation:
To show that the triangle is isosceles, we need to show that two of the sides of the triangle are equal.
Get AB
Using the formula for calculating the distance between two points
AB = √(x2-x1)²+(y2-y1)²
A(0,1), B(3,3)
AB = √(3-0)²+(3-1)²
AB = √3²+2²
AB = √9+4
AB = √13
Get BC
B(3,3), and C(3,-1)
BC = √(3-3)²+(-1-3)²
BC = √0²+-4²
BC= √0+16
BC = √16
BC = 4
Get AC
A(0,1), and C(3,-1)
AC = √(3-0)²+(-1-1)²
AC = √3²+(-2)²
AC = √9+4
AC= √13
Since AB = AC, this shows that the triangle ABC is an isosceles triangle.
The two sides that are congruent are AB and AC
