Given:
y = -3x + 5
5x - 4y = -3
Since we are given y, let’s sub it in the second equation.
5x - 4(-3x + 5) = -3
5x + 12x - 20 = -3
17x = 17
x = 1
After finding x, we can now find y.
5(1) - 4y = -3
-4y = -8
y = 2
Checking:
y = -3x + 5
2 = -3(1) + 5
2 = 2
5x - 4y = -3
5(1) - 4(2) = -3
-3 = -3

Step-by-step explanation:
Given data
Loan= $7500
rate= 5%
time= 5 years
Required
The final amount A
Let us apply the simple interest formula, we have
A= P(1+rt)

On a coordinate plane, point A is 7 units to the left. Point B is at (0, 0). Point C is 7 units to the right. Point D is 7 units up .Point E is 7 units down.
Which point is located at (0, –7)?
Answers
Answer:
point a
Step-by-step explanation:
(0,-7) would be left 7 units so its point a
Answer:
Point E
Step-by-step explanation:
In (x,y) it represents horizontal, then vertical coordinates. So, if x is 0, that means it hasn't moved left or right. Since y is -7, that means it when down by 7 units from the origin.
Use the following information to answer the question. The mean age of lead actresses from the top ten grossing movies of 2010 was 29.6 years with a standard deviation of 6.35 years. Assume the distribution of the actresses' ages is approximately unimodal and symmetric. Between what two values would you expect to find about 95% of the lead actresses ages
Answers
Answer:
You should expect to find about 95% of the lead actresses ages between 16.9 years and 42.3 years.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 29.6 years, Standard deviation = 6.35 years.
Between what two values would you expect to find about 95% of the lead actresses ages
By the Empirical Rule, within 2 standard deviations of the mean. So
29.6 - 2*6.35 = 16.9 years
29.6 + 2*6.35 = 42.3 years
You should expect to find about 95% of the lead actresses ages between 16.9 years and 42.3 years.

el hogar tienen un valor de $18,000.00. ¿Cuál es el patrimonio neto de Wanda?
$127,000.00
$88,206,00
O $25.236.00
$82,030.00
Answers
El patrimonio neto de Wanda sera simplemente la suma de todos los valores de los ahorros y bienes que ella tiene, menos las deudas que ella tiene.
Obtendremos que el patrimonio de Wanda es: $88,206,00
Para obtener esto, primero calculamos el valor de vienes y ahorros que Wanda tiene.
esto es:
$127,000 por la casa.
$25,236.00 en ahorros
$18,000.00 en artículos del hogar.
El total es:
$127,000 + $25,236.00 + $18,000.00 = $170,236
El total de deudas es:
$68,422.00 en su hipoteca
$8,477.00 de su tarjeta de crédito
$5,131.00 de una cooperativa de ahorro
La deuda total es:
$68,422.00 + $8,477.00 + $5,131.00 = $82,030
El patrimonio entonces es:
P = $170,236 - $82,030 = $88,206

Table is made, such that we take value of x and find value of y
You can take any values of x from negative values to positive values. I am taking values of x: 1,2,3,4,5 and find value of y.
So our table will be:
x y=x+1

Show how to use the greatest common factor of 84 and 72 to rewrite 84m - 72n as a product of two factors
Answers
Answer:
The simplified expression is: 12(7m - 6n)
Step-by-step explanation:
Greatest common factor between 84 and 72
We keep dividing 84 and 72, while they can be divided by the same factor. So
84 - 72| 2
42 - 36|2
21 - 18|3
7 - 6
So the greatest common factor is 2*2*3 = 12.
Rewrite 84m - 72n as a product of two factors
Evidencing 12
[tex]84m - 72n = 12(\frac{84m}{12} - \frac{72n}{12}) = 12(7m - 6n)[/tex]

Find the unknown side length of the rectangle if its area is 11m 2.
3 m
?
11 m
Answers
Answer:
the side length is 3.
Step-by-step explanation:
you would do 11/3 2/3
and you would get 3
The area of a shape is the amount of space it occupies
The width of the rectangle is 3 meters
The length of the rectangle is given as:
[tex]Length = 3\frac 23[/tex]
The area of the rectangle is given as:
Area = 11m^2
The area of the rectangle is calculated using:
[tex]Area = Length * Width[/tex]
So, we have:
[tex]11 = 3\frac 23* Width[/tex]
Express mixed number, as an improper fraction
[tex]11 = \frac {11}3* Width[/tex]
Multiply both sides by 3
[tex]33 = 11* Width[/tex]
Divide both sides by 11
[tex]3 = Width[/tex]
Rewrite as:
[tex]Width = 3[/tex]
Hence, the width of the rectangle is 3 meters

Answers
Answer:
Slope - intercept form [tex]y = \frac{14}{3} x + 34[/tex]
Step-by-step explanation:
Explanation:-
Given points are ( -9 ,-8 ) and (-6,6)
slope of given two points
[tex]m = \frac{y_{2} -y_{1} }{x_{2}-x_{1} } = \frac{6-(-8)}{-6-(-9)} = \frac{14}{3}[/tex]
The equation of the straight line passing through the points and having slope
[tex]y - y_{1} = m ( x - x_{1} )[/tex]
[tex]y - (-8) = \frac{14}{3} ( x - (-9) )[/tex]
3 y + 2 4 = 14 x + 126
3 y = 14 x + 126 - 24
3 y = 14 x + 102
[tex]y = \frac{14}{3} + \frac{102}{3}[/tex]
[tex]y = \frac{14}{3} x + 34[/tex]
Slope - intercept form y= mx +C
Slope - intercept form [tex]y = \frac{14}{3} x + 34[/tex]
