Solve the following quadratic by factoring. X2-5x=14

x=−2 or x=7

Step-by-step explanation:

Let's solve your equation step-by-step.

x2−5x=14

Step 1: Subtract 14 from both sides.

x2−5x−14=14−14

x2−5x−14=0

Step 2: Factor left side of equation.

(x+2)(x−7)=0

Step 3: Set factors equal to 0.

x+2=0 or x−7=0

x=−2 or x=7

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
