Respuesta:34p+16g=208
47p+16g=208
Explicación paso a paso:
Definamos p como el costo por libra de duraznos.
Definamos g como el costo por libra de uvas.
Como cada libra de duraznos se vende a $p, 34 libras de duraznos generarán 34p dólares. Por su parte, cada libra de uvas dará un total de 45g dólares. Por lo tanto, la suma total es 34p+45g=192.25.
De manera similar, si vendemos 47 libras de duraznos y 16 libras de uvas por $208, se establece la ecuación
47p+16g=208.
34p+45g=192.25
47+16g=208
Response:
Option B.
Step-by-step breakdown:
The general equation for the best fit line is
where a indicates the slope and b the y-intercept.
Utilizing a graphing calculator yields a=-4.54762 and b=43.7143. Hence, the equation for the best fit line can be represented as
Here,
Note: Alternatively, you can apply the following formula to compute the slope.
Accordingly, the correct choice is B.
Answer:
Anya's line has a slope of m = 3
Step-by-step explanation:
Explanation:-
Anya created a graph representing the line
(y−2)=3(x−1)
From this, we can deduce that the slope-intercept representation is
y = mx +c
Now by rewriting Anya's line
y−2=3(x−1)
⇒ y - 2 = 3x - 3
⇒ y = 3x - 3 + 2
⇒ y = 3 x - 1
<pBy comparing this with the slope-intercept structure<p y = mx +c<pwe conclude that Anya's slope is m = 3, and y-intercept is C = -1
Given parameters:
Equation:
(x-4)²=9
Problem: Solve the equation by both factoring and extracting the square root.
Solution:
Starting equation:
(x-4)²=9
Subtracting 9 from both sides brings us to zero;
(x-4)² - 9 = 0
(x -4)² - 3² = 0
This fits the concept of the difference of squares;
x² - y² = (x + y)(x-y)
Let x = x-4 and y = -3
Then input and solve;
(x - 4 -3)(x - 4 -(-3)) = 0
(x - 7)(x - 1) = 0
S thus,
x - 7 = 0 or x-1 = 0
x = 7 or 1
<pBy extracting the square roots;
(x-4)² = 9
√(x-4)² = √9
x - 4 = 3
x = 4 + 3 = 7; however, this is not the sole solution
Thus, direct extraction of the square root is not the method for complete solutions.
The predicted outcome is 83 minutes. I hope this is useful to you.
