Answer:
One solution at (-4, -22)
Step-by-step explanation:
5x - y = 2
y = 5x - 2 --(1)
2x - 0.5y = 3 --(2)
sub (1) into (2):
2x - 0.5(5x - 2) = 3
2x - 2.5x + 1 = 3
-0.5x = 2
x = -4
when x = -4, y = 5(-4) - 2 = -22
The nature of the solution set to the system of equations are,
⇒ One solution at (-4,-22).
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The system of equations are,
5x - y = 2 .. (i)
2x - 0.5y = 3 .. (ii)
Now, We can simplify as;
From (i);
5x - y = 2
y = 5x - 2
Put above value in (ii);
2x - 0.5 (5x -2) = 3
2x - 2.5x + 1 = 3
- 0.5x = 2
x = - 4
From (i);
y = 5 × - 4 - 2
y = - 20 - 2
y = - 22
Thus, The nature of the solution set to the system of equations are,
⇒ One solution at (-4,-22).

Simone claims that the slope of the line through (-2, 7) and (3, 0) is the same as the slope of the line through (2, 1) and (12, -13) is simone's claim true or false
Answer:
Simone is correct
Step-by-step explanation:
Given
Line 1:
[tex](x_1,y_1) = (-2, 7)[/tex]
[tex](x_2,y_2) = (3, 0)[/tex]
Line 2:
[tex](x_1,y_1) = (2, 1)[/tex]
[tex](x_2,y_2) =(12, -13)[/tex]
Required
Is Simone correct?
Slope (m) is calculated using:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
For Line 1
[tex]m = \frac{0 - 7}{3 - (-2)}[/tex]
[tex]m = \frac{0 - 7}{3 +2}[/tex]
[tex]m = \frac{-7}{5}[/tex]
[tex]m = -\frac{7}{5}[/tex]
For Line 2:
[tex]m = \frac{-13 - 1}{12 -2}[/tex]
[tex]m = \frac{-14}{10}[/tex]
Divide by 2/2
[tex]m = \frac{-14/2}{10/2}[/tex]
[tex]m = \frac{-7}{5}[/tex]
[tex]m = -\frac{7}{5}[/tex]
By comparison, both lines have the same slope.
Hence, Simone is correct

In the equation, y = 8.5x the variable y represents time and x represents the distance in miles.
What is a linear equation?The linear equation is defined as the equation having a degree of one or the power of the variable will be one. It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Given that John ran 3 miles in 25.5 min the equation y = 8.5x. The equation is satisfying the answers. The solution will be calculated as follows:-
y = 8.5x
Here, the y variable is the total time and x is the distance in miles.
y = 8.5x
For 3 miles the time will be calculated as follows:-
y = 8.5 x 3
y = 25.5 minutes
Therefore, in the equation, y = 8.5x the variable y represents time and x represents the distance in miles.

LSA of a cube is 1600cm2, then its edge is:
Answer:
20 cm
Step-by-step explanation:
A cube has 6 faces. Two of the faces are bases. The other four faces are lateral faces.
Let the area of 1 face = x
4x = 1600 cm^2
x = 400 cm^2
Since the area of 1 face is 400 cm^2, then the side length is sqrt(400 cm^2) = 20 cm
Answer: 20 cm

Profundidad = 40m
Costo de 1m² = $ 2100
Required
Determine el costo del terreno Primero, necesitamos determinar el área del terreno.
Primero, necesitamos determinar el área del terreno.
Área = Longitud * Profundidad
Valores sustitutos de Longitud y Profundidad
Área = 13m * 40m
Área = 520m²
A continuación, calculamos el costo del área calculada
Si 1m² cuesta $ 2100
Entonces
520m² cuesta $ 2100 * 520
Costo = $ 1092000
Por lo tanto, el costo de las dimensiones dadas es $1092000

Evaluate each value expression for the given value of x: 11 + x, x=12
Answer:
The value of 11+x at x=12 will be 23.
Step-by-step explanation:
Given the expression
[tex]11 + x[/tex]As we have to evaluate the expression at x=12
so substitute the value x=12 in the expression
[tex]11 + x[/tex]
[tex]=11+12[/tex]
[tex]=23[/tex]
Therefore, the value of 11+x at x=12 will be 23.
Which of these is a prime number?
733
712
702
725
Answer:
733
Step-by-step explanation:
712 and 702 end in 2, so they're divisible by 2.
725 ends in 5, so it's divisible by 5.
733 is not divisible by 2.
7 + 3 + 3 = 13, so 733 is not divisible by 3.
It looks like 733 is the prime number.
if
[tex]f(x) = \sqrt{x} + 12[/tex]
and
[tex]g(x) = 2 \sqrt{x} [/tex]
what is the value of
[tex](f - g)(144)[/tex]
?
Answer:
0
Step-by-step explanation:
We have the two functions:
[tex]f(x)=\sqrt{x}+12\text{ and } g(x)=2\sqrt{x}[/tex]
And we want to find (f-g)(144).
This is the same thing to f(144)-g(144).
So, let’s determine the value of f(144) and g(144) first:
[tex]\begin{aligned} f(144)&=\sqrt{144}+12 \\ &=12+12 \\ &=24\end{aligned}[/tex]
And:
[tex]\begin{aligned} g(144)&=2\sqrt{144} \\ &=2(12) \\ &=24 \end{aligned}[/tex]
Hence:
[tex]\begin{aligned} (f-g)(144) &= f(144)-g(144) \\ &=24-24 \\ &=0 \end{aligned}[/tex]
Our final answer is 0.
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex](f - g)(x) = \sqrt{x} + 12 - 2 \sqrt{x} \\ [/tex]
[tex](f - g)(x) = - \sqrt{x} + 12[/tex]
[tex](f - g)(144) = - \sqrt{144} + 12[/tex]
[tex](f - g)(144) = - \sqrt{ {12}^{2} } + 12 [/tex]
[tex](f - g)(144) = - (12) + 12[/tex]
[tex](f - g)(144) = - 12 + 12[/tex]
[tex](f - g)(144) = 0[/tex]
