Equation in point-slope form is:y+1=9(x+8)

Step-by-step explanation:

We are given slope m= 9 and point (-8,-1) and we need to find an equation in point-slope form for the line.

The standard equation of point-slope form is:

y-y_{1}=m(x-x_{1})

So putting value of slope m= 9 and x₁= -8 and y₁= -1 the equation in point-slope form is:

y-y_{1}=m(x-x_{1})\\y-(-1)=9(x-(-8))\\y+1=9(x+8)

So, equation in point-slope form is:y+1=9(x+8)

Bags of almonds cost three dollars more than bags of pecans the owner of a bakery ordered five bags of almonds and three bags of
antiseptic1488 [7]

Answer:

Let bags of pecans cost = x

Make an equation :

Bags of almonds cost = x + 3 (they said almonds cost 3 dollars more)

Total number of bags ordered: (3 bags pecans) + (5 bags of almonds)

Cost for pecans = 3x

Cost for almonds = 5(x + 3) = 5x + 15

Price of pecans + price of almonds = total cost

Solve for x:

3x + 5(x + 3) = 55 (remove brackets)

3x + 5x + 15 = 55 (add like terms)

8x + 15 = 55

8x + 15 - 15 = 55 - 15 (get rid of the 15)

8x = 40

8x/8 = 40/8

x = 5

bags pecans cost is $5

bags of almonds is $5+$3 = $8

Uma barraca de tiro ao alvo de um parque de diversão dará um prêmio de r$ 20ao participante cada vez que ele acertar o alvo por
zavuch27 [327]

Resposta: 30

Explicação passo a passo:

Dado o seguinte:

Preço para atingir a meta = $ 20

Penalidade por falta de alvo = $ 10

Se 80 tiros forem disparados e os participantes receberem $ 100.

Número de vezes que o participante atinge o alvo.

Deixe o número de erros = m

Deixe o número de acertos = h

h + m = 80 - - - - (1)

20h - 10m = 100 - - - (2)

h = 80 - m

Substitua h = 80 - m em (2)

20 (80 - m) - 10m = 100

1600 - 20m - 10m = 100

-30m = 100 - 1600

-30m = - 1500

m = 50

De (h = 80 - m)

h = 80 - 50

h = 30

Número de acertos = 30

O participante acerta o alvo 30 vezes
