Answer:

well, we know it is

y = -4 x + b

so all we need is b

5 = -4(9) + b

5 = -36 + b

b = 41

y = -4 x + 41

Kate decides to replace all the lights in her college apartment with energy saving light bulbs beginning this month. The packagi

svetoff [14.1K]

Kate's bill for this month for one bulb will be $1.8225

Further explanation:

Given

Old Bill for one bulb use = $7.29

Percentage of reduction in bill = 75%

To find the new bill, we have to find the amount of saving that Kate will get by using the energy saver and then the amount will be subtracted from the previous bill of $7.29

So, the new bill will be:

$New\ bill = Old\ bill- (saving)\\New\ Bill= 7.29 - (7.29 * \frac{75}{100})\\= 7.29 - 5.4675\\= 1.8225$

Hence the bill this month will be $1.8225

What is the slope of a line parallel to the graph of y-2=4(x+1)

Brrunno [24]

Answer:

Step-by-step explanation:

Basándonos en el hecho de que 2 rectas paralelas L1 y L2 son paralelas como lo indica el problema sabemos que m1=m2

por lo tanto si resolvemos la ecuación punto-pendiente que tenemos alli

y-2=4(x+1)

y-2=4x+4

y=4x+4+2

y=4x+6

De esta forma tendríamos la tan conocida ecuación de una recta

y=mx+b

Donde "m" es la pendiente de dicha recta y "b" es el punto de interseccion con el eje y

por lo tanto en este caso la pendiente m=4
