$\\ \sf\longmapsto f(x)=112-kx$

f(-3)=121

Put -3 in f(x)

$\\ \sf\longmapsto f(-3)=121$

$\\ \sf\longmapsto 112-k(-3)=121$

$\\ \sf\longmapsto 112+3k=121$

$\\ \sf\longmapsto 3k=9$

$\\ \sf\longmapsto k=3$

Julie works in chicago and has to pay $14 per day on tolls and $76 a day for gas. If she makes $19 an hour how many hours must s

enot [183]

Answer:

19 hours.

Step-by-step explanation:

T = -14 -76 + 19h

The -14 is the cost for tolls, and the -76 is the cost for gas. The 19h is the amount she'll get per hour if she makes $19/hour. And T is the total profit

We want to solve for h if T = 260

260 = -14 -76 + 19h

+14 +14

274 = -76 +19h

+76 +76

350 = 19h

/19 /19

18.42 = h

She must work 19 hours.

Hope this helps!

Helga [31]

Answer: Celine, 4092 ml

Step-by-step explanation:

Given

1 bottle contains 341 ml Juice

Celine buys 2 cases of 24 bottles i.e. a total of 48 bottles

Nicole buys 3 cases of 12 bottles i.e. a total of 36 bottles

Amount of Juice Celine has

$\Rightarrow 48\times 341=16,368\ ml$

Amount of Juice Nicole has

$\Rightarrow 36\times 341=12,276\ ml$

Thus, Celine has more juice than Nicole

$\Rightarrow 16,368-12,276=4092\ ml$

Celine has 4092 ml more than Nicole

50 point! Look at the picture attached. I will mark brainliest!

worty [1.4K]

Answer:

22°

Step-by-step explanation:

Triangle KJL ≅ Triangle MJL (RHS)

[JL = JL(common), KL = LM(given), angle KLJ = angle MLJ(given)]

we come up to the conclusion that 4x + 6 = 3x + 10

x = 4

∴angle KJL = 4(4) + 6 = 22°
