Answer: x = -1; y = -1
y = 3x + 2
y = -2x - 3
⇔ y = 3x + 2
3x + 2 = -2x - 3
⇔ y = 3x + 2
5x = -5
⇔ y = 3x + 2
x = -1
⇔ y = -1
x = -1

After paying seven dollars for the pie, Sara has ninety-six dollars left. How much money (m) did she have
before buying the pie? Do not include spaces in your answers.
Answer:
103
Step-by-step explanation:
bassically what you do is add 7 dollars to the ninety six that she lost when she bought the pie or you can do this equation 96 + m but m would be the money she lost being 7 dollars so you would replace m with 7 so it would be 96 + 7 = 103

Which values of a, b, and c correctly represent the answer in simplest forrn?
Answer:
The equation becomes
[tex]1\frac{7}{19}=a\frac{b}{c}[/tex]
Therefore,
a = 1b = 7c = 19Hence, option (C) is true.
Step-by-step explanation:
Given the expression
[tex]3\frac{1}{4}\div 2\frac{3}{8}\:=a\frac{b}{c}[/tex]
Solving the L.H.S of the equation
[tex]3\frac{1}{4}\div \:2\frac{3}{8}=\frac{13}{4}\div \:2\frac{3}{8}[/tex]
[tex]=\frac{13}{4}\times \frac{8}{19}[/tex]
[tex]=\frac{13\times \:2}{1\times \:19}[/tex]
[tex]=\frac{26}{1\times \:19}[/tex]
[tex]=\frac{26}{19}[/tex]
Converting improper fraction to a fixed number: [tex]\frac{26}{19}=1\frac{7}{19}[/tex]
[tex]=1\frac{7}{19}[/tex]
Thus, the equation becomes
[tex]1\frac{7}{19}=a\frac{b}{c}[/tex]
Therefore,
a = 1b = 7c = 19Hence, option (C) is true.

i need help with number 8
Answer:
Option (3)
Step-by-step explanation:
Given inequality is,
-2x + 8 < 12
By subtraction property of Order,
-2x + 8 - 8 < 12 - 8
-2x < 4
B division property of Order,
[tex]\frac{-2x}{(-2)}<\frac{4}{(-2)}[/tex]
x > -2
Since, there is no sign of equal to ( = ) in the given inequality, starting point on a number line will be a hollow point.
And an arrow starting from point x = -2 directing towards positive integers will represent the given inequality.
Option (3) will be the answer.

All sides are equal (60 degrees) so it is an equilateral triangle
A salesman made a trip of 480 miles by bus and train. He traveled 4 hours by
bus and 4 hours by train. On the average, the train was 20 mph faster than
the bus. Find the rate of each.
Answer:
bus = 50mph and train = 70mph
Step-by-step explanation:
4b + 4t = 480
t = b + 20 [replace the "t" in the next step to solve]
4b + 4(b + 20) = 480
4b + 4b + 80 = 480
8b + 80 = 480 [subtract 80 from both sides of the equation]
8b = 400 [divide by 8 on both sides of the equation]
b = 50 and if the train is 20mph faster, t = 70
4(50) + 4(70) = 480
Answer:
480

solve for x under the assumption that x<0. Enter your answer in interval notation using grouping symbols
Step-by-step explanation:
x² + 9x < -20
x² + 9x + 20 < 0
(x + 4)(x + 5) < 0
Therefore -5 < x < -4 / (-5,-4)

What is the slope of the line through (0, 5) and (-2, -1)
Answer:
3
Step-by-step explanation:
To find the slope of a line going through two points, (x₁, y₁) and (x₂, y₂), we can use the following formula: [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]. Note that it doesn't really matter which points we call (x₁, y₁) or (x₂, y₂).
Let's call (x₂, y₂) = (0, 5) and (x₁, y₁) = (-2, -1). Now, we can plug in the values for x, y₁, x₂, and y₂ into the formula.
We have:
[tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }=\frac{5-(-1)}{0-(-2)} =\frac{5+1}{0+2} =\frac{6}{2} =3[/tex]
Therefore, the slope of the line is 3. Hope this helps!
3/2+(-6/5)?? answer??
Answer:
I think The answer would be 0.3
Answer:
-3/10

2(3+2w+w)= 7 1/3
6+6w= 7 1/3
-6 both sides
6w=1 1/3
/6 both sides
w=2/9
2/9*2=4/9+3=3 4/9

is x^2 + 1/x = 4 a quadratic equations
Answer:
[tex]\large\boxed{\pink{ \leadsto The \ given \ equation \ is \ not \ a \ Quadratic \ equation . }}[/tex]
Step-by-step explanation:
Given equation to us is ,
[tex]\green{\implies x^2+\dfrac{1}{x}=4 }[/tex]
So , a equation is said to be a quadratic equation if the highest degree of the variable is 2 . On simplifying the Equation ,
[tex]\implies x^2 +\dfrac{1}{x}=4 [/tex]
Taking x as LCM ,
[tex]\implies \dfrac{x^2.x + 1 }{x}= 4 [/tex]
Transposing x to RHS .
[tex]\implies x^3 + 1 = 4x [/tex]
Putting all terms in LHS
[tex]\boxed{\bf \implies x^3 - 4x - 1 = 0 }[/tex]
Since here the highest degree of the variable is 3 not 2 . So its a cubic equation and not a quadratic equation .
Hence the given equation is not a quadratic equation .
