Solve:<br> a. 5y – 3 = – 18<br> b. -3x – 9 = 0<br> c. 4 + 3(z - 8) = -23<br> d. 1 – 2(y – 4) = 5
oksian1 [2.3K]

Answer:

a. y = -3

b. x = -3

c. z = - 1

d. y = -7

Step-by-step explanation:

a. 5y - 3 = - 18

5y = -18 +3

5y = -15

y = -15/5

y = - 3

b. -3x - 9 = 0

-3x = 9

x = 9/-3

x = -3

c. 4 + 3(z-8)= -23

4 + 3z-24 = -23

3z - 20 = -23

3z = -23 + 20

3z = -3

z = -3/3

z = - 1

d. 1 - 2(y-4) = 5

1 - 2y + 8 = 5

9 - 2y = 5

-2y = 14

y = 14/-2

y = -7

What are the solutions of the equation x4 + 95x2 – 500 = 0? Use factoring to solve.
VMariaS [17]

Given

The equation in the form

x^{4}+95x^{2}-500 =0

Find the factor of the above equation

To proof

factoring the above equation

we get

x^{4}+100x^{2}-5x^{2}-500 =0\\\\x^{2}(x^{2}+100)-5(x^{2}+100)=0\\\\(x^{2}-5)(x^{2}+100)=0

now sloving the equation we get the value

x² = 5

x² = -100

x =\pm \sqrt{5}\\\\ x=\sqrt{-100}

The factor of the equation is

x=\pm \sqrt{5}\\\\ x= \pm 10i

Hence proved

Problem
PolarNik [594]

Answer:

The equation of this line would be y = -8

Step-by-step explanation:

Since y = 9 is a horizontal line, the parallel line must also be horizontal. All horizontal lines can be written as y = (a number). That number can be found as the y-coordinate in the ordered pair, which is -8.

y = -8

6 is 15% of what number
navik [9.2K]
To solve this problem, you must set it up like this : 6/x = 15/100
Now, cross-multiply. 15x = 600
Divide by 15 on each side. 
x=40. 

6 is 15% of 40. 

Hope this helps :)
