Answer:
f>2 or f<-2
Step-by-step explanation:
f^2−9>−5
Add 9 to each side
f^2−9+9>−5+9
f^2 >4
Take the square root of each side, remembering to flip the sign of the inequality for the negative
f>2 or f<-2
Answer:
4/3
Step-by-step explanation:
encontrar el mínimo común denominadorienes para que sea mas facil
5/3+17/51-14/21 es 5/3 + 1/3 -2/3 cuando todos son igual de los denominados.
Ahora escribi todos los 3 numeros que iguale lo mismo denominador
5+1-2/3
Ahora solo hace el mas y menos y esta listo
4/3 es lo que pasa cuando haces las operaciones.
Answer:
Step-by-step explanation:
37.70
In order to solve this equation, let's write it out in number form:
-3 - x = -10
In order to isolate 'x' we need to ensure that there is only 'x' on one side. We can get rid of the -3 by adding 3 to both sides:
-3 + 3 - x = -10 +3
-x = -7
Because there are negatives on both sides, you can simply cancel them out:
x = 7
Answer:
y = 10
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° =
, then
sin30° =
=
=
( cross- multiply )
2y = 20 ( divide both sides by 2 )
y = 10
