Answer:
y = 2
Step-by-step explanation:
x + 5y - 10 = 0
X = 4y - 8
since x is given as = 4y - 8 we can use this in first equation
replace x with 4y - 8
x + 5y - 10 = 0 ➡ 4y - 8 + 5y - 10 = 0 add like terms
9y - 18 = 0 add 18 to both sides of the equation
9y = 18 divide both sides by 9
y = 2
You first have to turn 2x + 4y = -8 into y = mx + b before graphing. To do this, you subtract 2x from the left side of the equation because inverse operations. This will bring 2x to the right side. Now, you will have 4 = -2x + 8. However, you cannot have a number with y. Therefore, you must divide -8 and 2 by 4. You will get y = -1/2 x + 2 as your equation.
To graph -1/2x + 2, you must remember rise/run. Since it is NEGATIVE -1/2, your slope will go downwards (1 down, 2 across) starting from y = 2.
Resposta: a) R $ 114,40
Explicação passo a passo:
Dado o seguinte:
Preço à vista da mercadoria = R $ 130
Pagamento inicial = 20% na compra
O saldo pode ser parcelado, o que adicionará 10% ao saldo devedor.
Portanto ; Pagamento inicial :
20% * 130
0,2 * 130 = R $ 26
Saldo devedor = R $ (130 - 26) = R $ 104
Parcela total devida:
Saldo de débito + 10% do saldo de débito
10% do saldo devedor:
0,1 * 104 = R $ 10,40
Parcela total:
R $ (104,00 + 10,40) = R $ 114,40
No because the 3 is the tens place. So its supposed to 3 ten blocks
Answer:
D) 1
Step-by-step explanation:
Every whole number (including the ones on a die) are either even or odd, nothing else. So it is guaranteed for the number to be even or odd.
