how do you graph this linear equation???
Answers
Answer:
You can choose x as any value like x = 7
if x were to equal 7 then
the equation would be y = 2 times 7 - 1
2 times 7 = 14 and 14-1 = 13
y would be 13 ifi x was 7
so you can graph the point 7,13

Answers
Answer:
a = 6, b = - 12
Step-by-step explanation:
Expand the left side and compare the coefficients of like terms to those on the right side.
a(4x - 10) ← distribute parenthesis
= 4ax - 10a
Compare to 24x + 5b , then
4a = 24 ( divide both sides by 4 )
a = 6
Then
5b = - 10a = - 10(6) = - 60 ( divide both sides by 5 )
b = - 12
2 litres of lemonade costs £2.60. Find the cost of 6 litres of lemonade
Answers
Answer:
£7.80
Step-by-step explanation:
Since you multiply 2 by 3 to get 6, we are going to multiply 2.6 by 3
2.6 x 3 = 7.8
Thus the cost of 6 litres of lemonade is £7.80

.- Sí 159.6 gramos de Fe2O3 liberan 67.2 litros de CO2 ¿cuántos litros de CO2 se liberan si reaccionan 45 gramos de Fe2O3? de acuerdo a la siguiente reacción: Fe2O3 (s) + 3 CO (g) 2 Fe (s) + 3 CO2 (g)
Answers
Answer:
45 g de oxido de hierro (III) liberarán 18.9 L de CO₂
Step-by-step explanation:
La reaccion quimica es la siguiente:
Fe₂O₃ (s) + 3CO (g) → 2Fe (s) + 3CO₂ (g)
1 mol de oxido de hierro (III), reacciona con 3 moles de monoxido de carbono para liberar 3 moles de CO₂ y 2 moles de Fe sólido.
Pasamos la masa de F₂O₃ a moles:
159.6 g . 1 mol /159.7g = 1 mol de oxido
Entonces, aplicamos la regla de tres:
1 mol de oxido produce 3 moles de dioxido de carbono, indudablemente eso será lo que formemos de producto, por lo tanto 3 moles de CO₂ estan ocupando 67.2 litros.
Ahora calculamos los nuevos moles:
45g . 1 mol /159.7 g = 0.282 moles
Aplicamos la regla de tres:
Si un mol de oxido produce 3 moles de CO₂
0.282 moles producen (0.82 . 3 ) = 0.845 moles de CO₂
Como tenemos menos moles de gas, el volumen ocupado sera mayor, hacemos la regla de tres:
Si 3 moles de CO₂ ocupan 67.2 litros
0.845 moles ocuparan (0.845 . 67.2/ 3 ) = 18.9 litros

12 = 3(m - 17)
Help please. You have to use distributive property to solve.
Answers
Answer:
m = 21
Step-by-step explanation:
12 = 3(m - 17)
12 = 3m - 51 (Found using the distributive property)
63 = 3m (Found by adding 51 to both sides)
21 = m (Found by dividing both sides by 3)

Kieran picks a bead out of a bag without looking.He records the colour and replaces the bead.Kieran does this 50 times.He picks out a red bead 15 times. Estimate the probability of picking a red bead.
Answers
Answer: 3/10
Step-by-step explanation:
From the question, we are informed that Kieran picks a bead out of a bag without looking and that he records the colour and replaces the bead.
He does this 50 times and he picks out a red bead 15 times. The probability of picking a red bead will be the number of times a red bead was picked divided by the number of title times a bead was picked. This will be:
= 15/50
= 3/10
