Answer:
what do you need help with
Step-by-step explanation:
Answer:
similar SAS
Step-by-step explanation:
because the angle c has the angle c and sides are cb,ba .
because the angle d has the angle d and slide are df, Fe
Let and . By the product rule,
By the power rule, we have and , but are functions of , so we also need to apply the chain rule:
and we have
So we end up with
Replace to get everything in terms of :
We can simplify this by factoring:

Answer:
x > -4
Step-by-step explanation:
Inequalities like these are solved the same way equations are solved, except when multiplying both sides you flip the less than/greater than sign:
3x + 7 > -x -9
3x + 7 - 7 > -x -9 -7 Subtract 7 from both sides
3x > -x -16
3x + x > -x -16 + x add x to both sides
4x > -16
> divide both sides by 4
x > -4
In this case the inequality sign did not have to be flipped since we never multiply both sides by a negative number.
