Answer:
x=11
Step-by-step explanation:
your equation would be
4x+7+39+90=180
136+4x=180
4x=44
Immediately omit the negative possible answer. Since 5^2 = 25, 1/5^2 = 1/25.
A1. 12 i.e option D
A2. 3n-7 i.e option A
A3. -6n+20 i.e option D
A4. -70 i.e option C
Step-by-step explanation:
aₙ = a₁ + (n - 1) × d
aₙ = the nᵗʰ term in the sequence
a₁ = the first term in the sequence
d = the common difference between terms
Using the above formula to solve the first part, we have :
For the second part, we have :
For the third part, we have :
For the fourth part, we have :
The denominator of the second fraction can be factored as (a-2)(2a-7), then it becomes doable. You cancel the (2a-7) factors, and are left with:
Do note that you have erased the fact that a≠0 and a≠7/2, so you should always mention that.
Answer:
Parallel Slope: -3 Perpendicular Slope: 1/3
Step-by-step explanation:
First, solve for y to get the simplified equation for the line.
Once you solve, the equation should be y=-3x+2
Seeing this, we know that the slope of this line is -3. A line parallel will have the same slope as the original equation, and a line perpendicular will have a slope that is the opposite reciprocal.
Hope that helps!
