Answer:
x=-5 y=5 (-5,5)
Step-by-step explanation:
(6x-y=-35)-2
5x-2y=-35
-12x+2y=70
5x-2y=-35
-7x=35
x=-5
5(-5)-2y=-35
-25-2y=-35
-2y=-10
y=5

Answer:
-4n(squared)+11.8n
Step-by-step explanation:
Answer:
11.8n - 4n^2
Step-by-step explanation:
To solve this equation, we can combine like terms together:
3.8n - 4n^2 + 8n = 11.8n - 4n^2
Since we can't combine anymore like terms, or simplify, this will be our answer!

A quadratic function y = f(x) is plotted on a graph and the vertex of the resulting
parabola is (-6, -3). What is the vertex of the function defined as
g(x) = -f(x) + 3?
Answer:
(6, 6).
Step-by-step explanation:
The negative before f(x) reflects f(x) in the x-axis so this makes the new vertex equal to (-6, 3), then the + 3 translates it up 3 units so the required vertex is
(-6, 6).

Keegan and Jeff did some research and found that there are approximately 7,492,000,000,000,000,000 grains of sand on Earth. Jeff says that it is about 7 × 10(15) grains of sand. Keegan says that this is about 7 × 10(18) grains of sand
Answer:
Using the latest geological studies, they calculate the total volume of sand on Earth. Scientists estimate that Earth contains 7.5 sextillion sand grains. ... Astronomers estimate there exist roughly 10,000 stars for each grain of sand on Earth. That's a lot of stars.

Y-2 = ½(X-3)
Answer:
(If solving for x) X = 2y-1
Step-by-step explanation:
Y-2 = 1/2(x-3)
Distributive property
Y-2 = 1/2x - 1.5
Addition property of equality
Y-0.5=1/2x
Multiplication property
2Y-1=X
Symmetric property
X = 2y-1

Inez and Joel work at a store that sells
cell phones. Inez worked for 7 hours
and 23 minutes. Joel worked for
4 hours and 51 minutes. How much
longer did Inez work than Joel?
2 hours 32 minutes
12 hours 14 minutes
3 hours 28 minutes
3 hours 32 minutes
Answer:
2 hrs and 32 mins
Step-by-step explanation:
Step 1. Because Inez worked more we are going to start by subtracting the the minutes. 23-51= -28.
Step 2. Now we move on to the hours. 7-4= 3. Know we know that the hour time is going to be three. But wait!
Step 3. Because we can't have negative numbers, we need to subtract some more. 60-28= 32. Now I know that my minutes will be 32.
Step 4. But because we used a negative number we have to subtract another hour from our time.
Answer: 2 hrs and 32 mins
Hope this helps!

Sarah Drew was the top scorer in a women's professional basketball league for the 2006 regular season, with a total of 856 points. The number of two-point field goals that Sarah made was 67 less than double the number of three-point field goals she made. The number of free throws (each worth one point) she made was 32 less than the number of two-point field goals she made. Find how many free throws, two-point field goals, and three-point field goals Sarah Drew made during the 2006 regular season.
Answer:
Free throws= 309 goals
Two-point field goals=341 goals
Three-point field goals=204goals
Step-by-step explanation:
This is a word problem, let us bring out all varibles
Let the number of three-point field goals =x
Two-point field goals= 2x-67
Free throws =(2x-67 )-32
Free throws =2x-67-32
Free throws =2x-99
Hence the mathematical expression for the total goals is
x+2x-67 +2x-99= 856
collecting like terms
x+2x+2x-67-99=856
5x-166=856
5x=856+166
5x=1022
divide both sides by 5 we have
x=1022/5
x=204.4
hence
1. Three-point field goals=204goals
2. Two-point field goals= 2x-67
=2(204)-67
=408-67
=341 goals
3. Free throws =2x-99
=2(204)-99
=408-99
=309 goals
