Which could be the first step in solving this system of equations by substitution?
y = 7x
y - x = 15
Answer:
The first step is to replace the y in y-x=15 with 7x (we can do this because the first equation tells us that they're equal)
solve and get
(2.5,17.5)
or x= 2.5 y=17.5
Step-by-step explanation:
The first step is to recognize that y=7x which means that we can just replace the y in the second equation with 7x
7x-x=15
6x=15
x=2.5
Then we can solve for y
y=7(2.5)
y=17.5
simplify 2x²/x²-7x+12 - x²+9/x²-7x+12
Answer:
(x+3)/(x-4)
Step-by-step explanation:
[2x²/(x-4)(x-3)] - [x²+9/(x-4)(x-3)] =
(x²-9)/(x-4)(x-3) =
(x+3)(x-3)/(x-4)(x-3) =
x+3/x-4
Answer:
2x²/x² - 7x + 12 - x² + 9/x² - 7x + 12
2x²/x² simplifies to just 2 (the x²s cancel out)
2 - 7x + 12 - x² + 9/x² - 7x + 12
add like terms: (2 + 12 + 12) + (-7x - 7x) - x² + 9/x²
= - x² - 14x + 9/x² + 26

Answer: The answer is x=[tex]\frac{-3-\sqrt{65} }{4}[/tex], [tex]\frac{-3+\sqrt{65} }{4}[/tex]
Step-by-step explanation:
1) You can solve a situation like [tex]ax^2+bx+c=0[/tex] using the quadratic formula
[tex]x=-b[/tex]±[tex]\sqrt{b^2-4ac}[/tex] / 2a
2) Apply that to the problem and we get x= -3±[tex]\sqrt{3^2-4*2*(-7)}[/tex]/2*2
3) Solve what's inside the square root and what's at the denominator --> x=-3±[tex]\sqrt{65}[/tex]/4
4) separate the solutions ---> [tex]x=\frac{-3+\sqrt{65}}{4} , \frac{-3-\sqrt{65}}{4}[/tex]
5) Your final solutions are [tex]x=\frac{-3+\sqrt{65}}{4} , \frac{-3-\sqrt{65}}{4}[/tex]

Sophie has 327 inches of wire. She needs 500 inches of wire to complete her project. Which equation will help Sophie figure out how much wire she needs to buy?
A. w – 500 = 327
B. w – 327 = 500
C. 327 + w = 500
D.500 + 327 = w
Answer:
C
Step-by-step explanation:
if you take 327+w=500 you would have to subtract 500-327 then you would get 173
Answer:
The answer would be C.
Step-by-step explanation:
Because 327+ 173 = 500

A shirt cost $21 last month. This month the price decreased by 30%. What is the new price?
Answer:
$14.70
Step-by-step explanation:
Find the 30% decrease:
21*0.3 = 6.3
Find new price:
21-6.3 = 14.7
Answer:
$14.7
Step-by-step explanation:
First, we need to convert the percentage to a decimal. 30% = .30
Now we multiply the price times the decimal, 21 x .30 = 6.3
We subtract this amount from the previous cost. 21 - 6.3= $14.7
Mr. Gephart is traveling from his house to the history museum. How many meters will he travel to the museum? The distance from home to the history museum is six and seven-tenths kilometers.
Answer: 6700 meters
Step-by-step explanation:
From the question given, we are informed that Gephart is traveling from his house to the history museum and that the distance from home to the history museum is six and seven-tenths kilometers.
In order to know the distance in meters
that he will travel to the museum, we have to multiply the convert the distance given in kilometers to meters. This will be:
1000 meters = 1 kilometer
Therefore, 6 7/10km = (6 7/10 × 1000m)
= 6 7/10 × 1000
= 67/10 × 1000
= 67 × 100
= 6700 meters
He'll travel 6700 meters to the museum.

What is the equation of the line that passes through (-1,-4) and (2,5)
A. y+1=3(x+4)
B. y+4=-3(x+1)
C. y+4=3(x+1)
D. y-4=-3(x-1)
Answer:
c) y+4=3(x+1)
Step-by-step explanation:
Answer:
C. [tex]y+4=3(x+1)[/tex]
Step-by-step explanation:
Hi there!
What we need to know:
All the given equations are in point-slope form: [tex]y-y_1=m(x-x_1)[/tex] where m is the slope and the given point is [tex](x_1,y_1)[/tex]1) Determine the slope of the line
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the points (-1,-4) and (2,5)
[tex]=\frac{5-(-4)}{2-(-1)}\\=\frac{5+4}{2+1}\\=\frac{9}{3}\\=3[/tex]
Therefore, the slope of the line is 3. Plug this into [tex]y-y_1=m(x-x_1)[/tex] :
[tex]y-y_1=3(x-x_1)[/tex]
2) Plug the point (-1,-4) into [tex]y-y_1=3(x-x_1)[/tex]
[tex]y-(-4)=3(x-(-1))\\y+4=3(x+1)[/tex]
Therefore, the correct answer is C.
I hope this helps!
