Use the given x-values to identify solutions as ordered pairs to the equation y = −7x + 4 for x = 1, 3, 5, and 7

1 answer:

8 0

For x=1: -7 x 1 + 4 = -3 y=-3
The ordered pair:(1, -3)
for x=3: -7 x 3 + 4 = -17    y=-17
The ordered pair:(3, -17)
for x=5: -7 x 5 + 4 = -35    y=-35
The ordered pair:(5, -35)
for x=7: -7 x 7 + 4 = -45    y =-45
The ordered pair:(7, -45)

Savannah needs to order some new supplies for the restaurant where she works. The

olga2289 [7]

Answer:

$s\geq 36$

Step-by-step explanation:

Step 1, how many knives to buy?

The restaurant already has 262 knives. We can subtract this number from their needed 694 knives to find how many they still need:

$694-262=432$ knives.

Step 2, how many sets of knives?

The restaurant needs to buy 432 knives. We know the knives come in sets of 12, so we can divide to find the # of packs she needs to buy, determined by variable s.

Notice how the restaurant needs to buy a minimum of 694 knives, hence we use a greater or equal than symbol:

$\fbox{\frac{432}{12} \geq s}\\$ $s\geq \frac{432}{12}$

$s\geq 36$

I hope this helps! Let me know if you have any questions :)

Suppose there is a 1.2 Fahrenheit drop in temperature for every thousand feet that an airplane climbs into the sky if the temper

Nostrana [21]

Answer:

58.7 °F

Step-by-step explanation:

At 5000 feet, the airplane is 5 times 1000 feet above the ground, so the temperature will have dropped 5 times 1.2 °F.

64.7 - 5×1.2 = 64.7 -6.0 = 58.7

At 5000 feet, the temperature is 58.7 °F.

Round your answer to the nearest hundredth

Anton [14]

Answer:

9.49

Step-by-step explanation:

Using the Pythagorean Theorem, we know a²+b²=c².

So 3²+9²=(BA)²

9+81=(BA)²

90=(BA)²

From this, we know BA=√90

BA=9.486

Rounding to the nearest hundredth, this is 9.49
