Answer:
13, 17, 19
Step-by-step explanation:
Go through (12-20) and find the multipliers for each number.
13 = 13 x 1
14 = 7 x 2 , 14 x1 = no
15 = 5 x 3, 15 x 1 = no
17 = 17 x 1
18 = 6 x 3, 9 x 2, 18 x 1 = no
19 = 19 x 1
<span>In order for an equation to have an infinite number of answers, the simplified equation should be x=x. In evaluating the above equation, -3 inserted in the box results in this simplified equation. The answer is therefor #1: -3</span>
Answer:
It should be -2x +6
Step-by-step explanation:
8x - 9y = 1
Solve for y:
-9y = -8x + 1
y = 8/9 x - 1/9
The slope of the given line is 8/9, so the slope of the perpendicular is -9/8.
y = mx + b
y = -9/8 x + b
The perpendicular passes through (3, -4).
-4 = -9/8 * 3 + b
-4 = -27/8 + b
b = -32/8 + 27/8
b = -5/8
The equation in slope-intercept form is
y = -9/8 x - 5/8
Now we change the equation to standard form.
8y = -9x - 5
The equation in standard form is
9x + 8y = -5
