The diagonals of a rectangle are equal.
So:
[tex]x + 5 + 2x -2 = 3x -9+4x - 16[/tex]
[tex]x + 2x + 5 - 2 = 3x +4x - 9 - 16[/tex]
[tex]3x + 3 = 7x -25[/tex]
Collect Like terms
[tex]3x-7x=-25-3[/tex]
[tex]-4x=-28[/tex]
[tex]x = \frac{-28}{-4}[/tex]
[tex]x = 7[/tex]
A line has a slope of a and has a y-intercept of (0,b). Which equation represents this line?
A. y-b=a(x-0)
B. y+b=a(x-0)
C. y-0=a(x-b)
D. y-0=a(x+b)
PLEASE HELP GIVING 50 POINTS!!!
Step-by-step explanation:
General line equation: y = mx + c, where m is the slope of the line and c is the y-intercept.
We have y = ax + b.
=> y - b = ax
=> y - b = a(x - 0).
The answer is option A.
Answer:
A
[tex]general \: equation \: of \: line \\ y = mx + c \\ from \: the \: data \: given \\ m = a \\ c = b \\ y = ax + b \\ y - b = ax \\ y - b = a(x - 0)[/tex]

The blue segment below is a radius of 0. What is the length of the diameter
of the circle?
What is the slope. Write the answer in simplest form.
Answer:
-1/4
Step-by-step explanation:
Points: (-8, -3), (-24, 1)
slope = rise/run = difference in y / difference in x
Find the difference in the y-coordinates in either order:
Let's do 1 - (-3) = 1 + 3 = 4
Now we find the difference in x, but it must be in the same order we did the difference in y.
-24 - (-8) = -24 + 8 = -16
Difference in y = 4
Difference in x = -16
slope = 4/(-16) = -1/4
Answer: -1/4

A coin contains 9 grams of nickel and 16 grams of Copper, for a total of 25 grams. What percentage of the metal is copper?
Answer:
The copper percentage = 64%
Step-by-step explanation:
Given
Nickle quantity = 9 grams of nickelCopper quantity = 16 grams of nickelTotal quantity = 25 gramsThe percentage of copper metal can be determined using the formula
Copper percentage = [Copper quantity / Total quantity] × 100
= [16 / 25] × 100
= 0.64 × 100
= 64%
Therefore, the copper percentage = 64%

Kim rols three 6 sided dice.
The product of her numbers is 60
a) What numbers could she have rolled?
Answer:
2,5,6
Step-by-step explanation:
2 * 5 * 6 = 60
Kim rolls three 6 sided dice. The product of her numbers is 60. So, the numbers are 2, 5, and 6 and this can be determined by using arithmetic operations.
Given :
Kim rolls three 6 sided dice.The product of her numbers is 60.The following steps can be used to determine the number could Kim has rolled:
Step 1 - Let the three numbers be a,b, and c.
Step 2 - Given that the product of these numbers is 60.
[tex]a\times b \times c = 60[/tex]
Step 3 - So, the possible values of a, b, and c are:
a = 2
b = 5
c = 6
Step 4 - Check the product of a, b, and c if it is 60 then it is correct.
[tex]2\times 5\times 6 = 60[/tex]

ABC dilated
Step-by-step explanation:
Given
Triangles ABC and DEF
Required
Determine the scale of dilation
First, we pick a side on ABC
[tex]AB = 6[/tex]
Pick a corresponding side on DEF
[tex]DE = 3[/tex]
The scale factor is then calculated as:
[tex]Scale\ Factor = \frac{DE}{AB}[/tex]
[tex]Scale\ Factor = \frac{1}{2}[/tex]
i.e. ABC was dilated by 1/2
