Is EF and GH parralel and how can this be determined?
Answer:
We have slope of EF : [tex]\mathbf{\frac{-4}{5}}[/tex] and slope of GH: [tex]\mathbf{\frac{-4}{5}}[/tex]
Both have same slope, so EF is parallel to GH i.e. EF || GH
Step-by-step explanation:
We need to find Is EF and GH parallel.
If EF and GH are parallel, they have same slopes.
So, we will find slopes of EF and GH
The formula used is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope of EF
We have: E(2,5) and F(7,1)
So, [tex]x_1=2, y_1=5, x_2=7, y_2=1[/tex]
Putting values in formula and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{1-5}{7-2}\\Slope=\frac{-4}{5}\\[/tex]
So, slope of EF is [tex]\mathbf{\frac{-4}{5}}[/tex]
Slope of GH
We have: G(2,-3) and F(-3,5)
So, [tex]x_1=2, y_1=-3, x_2=-3, y_2=5[/tex]
Putting values in formula and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{5-(-3)}{-8-2}\\Slope=\frac{5+3}{-10}\\Slope=\frac{8}{-10}\\Slope=\frac{-4}{5}[/tex]
So, slope of GH is [tex]\mathbf{\frac{-4}{5}}[/tex]
We have slope of EF : [tex]\mathbf{\frac{-4}{5}}[/tex] and slope of GH: [tex]\mathbf{\frac{-4}{5}}[/tex]
Both have same slope, so EF is parallel to GH i.e. EF || GH

Christine is saving money to buy a bike. She has 63 and is going to save an additional 9 each week. The bike costs 198 . In how many weeks will she have enough money to buy the bike?
Write an equation that could be used to answer the question above. First, choose the appropriate form. Then, fill in the blanks with the numbers 9,63, and 198 . Let w represent the number of weeks.
_w-_=_ or _w+_=_
(b) Solve the equation in part (a) to find the number of weeks.
_
Answer:
try adding them togther
Step-by-step explanation:
Answer: 9w+63=198
w=15
Step-by-step explanation:
198-63=135
135 divided by 9 would then equal 15

Sarah colored 1/2 of some birthday cards, and Rana colored 3/8 of them. If there are 32 cards in all, how many are left to be colored?
Answer: 4 cards are left to be colored.
Step-by-step explanation:
As per given,
Fraction of total cards colored = [tex]\dfrac12+\dfrac38[/tex]
[tex]=\dfrac{4+3}{8}\\\\=\dfrac{7}{8}[/tex]
Fraction of cards left to be colored = [tex]1-\dfrac78=\dfrac18[/tex]
Total cards = 32
Number of cards to be colored = [tex]\dfrac18\times32=4[/tex]
Hence, 4 cards are left to be colored.

Answer:
[tex]\text{(c)} \quad 9m^6-12m^4-6m^3-3m^2[/tex]
Step-by-step explanation:
As is often the case with multiple choice questions, you only need to identify a feature of the answer set that distinguishes right from wrong. Here, that can be the lowest-power term, which is always the product of the lowest-power terms.
That product is (-3m)(+m) = -3m². This matches the third answer choice.
[tex]9m^6-12m^4-6m^3-3m^2[/tex]

Answer:
x = 2
Step-by-step explanation:
Given
- 2(1 - 4x) = 3x + 8 ← distribute left side
- 2 + 8x = 3x + 8 ( subtract 3x from both sides )
- 2 + 5x = 8 ( add 2 to both sides )
5x = 10 ( divide both sides by 5 )
x = 2
