I'll solve B, and then challenge you to do A and C on your own!

If the line passes through (-3,4) and (5, -4), then the slope is the change in y over the change in x, which is (4-(-4))/(-3-5)=8/-8=-1 in this scenario, meaning that in the equation y=mx+b (with m as the slope), we have y=-x+b so far.Note that we only have to find b, as y and x can stay as variables. Plugging (-3,4) in for y and x (to find B), we get 4=-(-3)+b=3+b. Subtracting 3 from both sides, we get b=1 and the equation being y=-x+1

razones y proporciones. un pelotero profesional ha bateado 14 imparables , en 40 turnos al bate . hallar la razón entre las vece
ElenaW [278]

Answer:

El pelotero ha bateado imparables en el 35% de sus intentos.

Step-by-step explanation:

Dado que un pelotero profesional ha bateado 14 imparables en 40 turnos al bate, para hallar la razón entre las veces que ha bateado imparables y los turnos que ha tenido que batear se debe realizar el siguiente cálculo:

14 / 40 = X

0.35 = X

0.35 x 100 = 35

Por lo tanto, el pelotero ha bateado imparables en el 35% de sus intentos.

Which frequency table shows the test times (in minutes) for a reading test?
Naily [24]

In case the given numbers are :

81 63 61 58 72 70 79 68 82 64 54 82 72 63 64 76 57 64 73 58

we have :

50-59 , frequency is 4 (58, 54, 57, 58)

60 - 69, frequency is 7 ( 63, 61, 68, 64, 63, 64, 64)

70 - 79, frequency is 6 (72, 70, 79, 72, 76, 73)

80-89, frequency is 3 (81, 82, 82)

So correct option which matches the above data is option second.

Answer is table number two.
