Answer:
El área a cubrir es de 4800 cm^2.
Step-by-step explanation:
<em>La pregunta está incompleta:</em>
<em>Laura quiere cubrir con papel de china una puerta como la que se muestra en el dibujo cuánto es centímetros cuadrados. Las medidas son 80 cm de largo y 60 cm de ancho.</em>
Tenemos que calcular el área que representa la puerta, cuyos lados son 80 cm y 60 cm.
El área A se calcula multiplicando ambos lados:
The regression equation to predict the number of cans sold on a day that is 90°F will be 871.
<h3>What is the linear system?</h3>
A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
A convenience store manager notices that sales of soft drinks are higher on hotter days, so he assembles the data in the table, shown above. Use technology to find the equation of the least-squares regression line.
Then the regression line will be passing through (55, 340) and (84, 780). Then we have
y - 340 = 15.17(x - 55)
Then the regression equation to predict the number of cans sold on a day that is 90°F will be
y - 340 = 15.17 (90 - 55)
y = 871

Answer: (3, 10)
Step-by-step explanation:
X=3 y=10
<span>2x-3y=12 -
4x+6y=5
You want to get rid of y first so multiply the first equation by 2:
4x - 6y = 24
-4x + 6y = 5
now add the 2 equations together:
but as you can see, you cant solve this and if you add the equations together you get 0 = 29
so in result the answer is No Solution</span>
Hey! For these questions I'd reccomend m4thm4y. Ps I replaced the a with 4.
