The answer is <span>x - 1 = 3x + 9

All steps are:
</span>Step 1: 4ˣ⁻¹ = 64ˣ⁺³<span> 
Step 2: 4</span>ˣ⁻¹ = (4³)ˣ⁺³ <span>
Step 3: 4</span>ˣ⁻¹ = 4³ˣ⁺⁹ 
Step 4: x - 1 = 3x + 9
Step 5: x - 3x = 1 + 9
Step 6: -2x = 10
Step 7: x = 10/-2
Step 8: x = -5

3(x-7)+8=-20<br><br><br><br>can someone explain how to do this step by step​
Mrrafil [7]

3(x-7)+8=-20

Multiply the bracket by 3

(3)(x)(3(-7)+8= -20

3x-21+8= -20

3x-13= -20

Move -13 to the other side. Sign changes from -13 to +13.

3x-13+13= -20+13

3x= -7

Divide by 3

3x/3= -7/3

x= -7/3 or in mixed number : -2 1/3

Answer : x= -7/3 or in mixed number : -2 1/3

Which relationship has a zero slope? A two column table with five rows. The first column, x, has the entries, negative 3, negati
Anon25 [30]

Answer:

The one in the table on the left

Note that for the given values of x all of the y values are 2

This indicates a horizontal line, parallel to the x- axis with a slope of zero.

The equation of the line is y = c where c is the value of the y- coordinates the line passes through, in this case 2, thus

y = 2 is the equation of the line with zero slopeation

one of them is an undefined slope the other is a positive slope (Neither of them are a zero slope)
