Answer:
f(-1) = 8
Step-by-step explanation:
f(-1) = x
f(-1) = -5(-1) + 3
f(-1) = 8
Use one of the many Trigonometric ratios to solve for the missing angle and then use Pythagorean theorem to solve for the missing side.
These things can be done in any order.
Answer:
D. w < 3.3
Step-by-step explanation:
It cannot be A because a book is 2.3 pounds. (w > 2.3) it would be correct if it was (w ≥ 2.3)
It cannot be B because majority of the books has a greater mass than 2.4 pounds. (w < 2.4)
It cannot be C because all books have a lesser mass(or equal mass) than 3.2 pounds (w > 3.2)
It is D because W is less than 3.3 pounds ( w < 3.3)
Step-by-step explanation:
angle S + angle W + angle STW = 180
(7x + 6) + (7x + 1) + angle STW = 180
So angle STW = 180 - (7x + 6) - (7x + 1)
angle STW + angle STP = 180 (straight angle = 180)
180 - (7x + 6) - (7x + 1) + angle STP = 180
angle STP = 180 - 180 + (7x + 6) + (7x + 1)
= 7x + 6 + 7x + 1
= 14x + 7
15x = 14x + 7
x = 7
angle STP = 15x = 15(7) = 105
Basically just convert this into an equation:
Let’s use “x” as the result
“•” is the multiplication symbol
Double s: s•2
Subtract t from result: =x-2
So, s•2=x-2
