Mathematics
1 answer:
sineoko [7]4 years ago
8 0

Answer:

equation of the table is y=30x+60

60 degrees is what the temperature starts at

to get to 440 degrees he needs 12 minutes and 40 seconds

Step-by-step explanation:

the change in y over change in x is 90/3 which is the slope

slope is 30

if slope is 30 then 30*2+b=120 60+b=120 so b=60 and it is the y intercept

440=30x+60

380=30x

x=12 2/3

x= 12 minutes and 40 seconds

Emily measures 3 pieces of string with the first piece measures 642 cm the second piece measures 124 cm and the third piece is 1
NeX [460]

Answer: the total length of the string is 9 meters.

Step-by-step explanation:

The total number of strings that Emily measured is 3.

The length of the first piece of string measures 642 cm.

The length of the second piece of string measures 124 cm.

The length of the third piece of string measures 134 cm.

Therefore, the total length of the 3 pieces of string would be

642 + 124 + 134 = 900 cm.

100 cm = 1 m,

Converting 900 centimeters to meters, it becomes

900/1100 = 9 meters

Write a linear function f with the values f(10)=5 and f(2)=-3
Nutka1998 [239]

Answer:

f(x)=x-5

Step-by-step explanation:

step 1

Find the slope m

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have the ordered pairs

(10,5) and (2,-3)

substitute the values

m=\frac{-3-5}{2-10}

m=\frac{-8}{-8}

m=1

step 2

Find the equation of the line in slope intercept form

f(x)=mx+b

we have

m=1

point\ (10,5)

substitute and solve for b

5=(1)(10)+b

5=10+b

b=-5

The linear function is equal to

f(x)=x-5

A triangle has 3 sides, 10000, 1000, 10x. Find 10x. What 2 numbers can x be between.
Debora [2.8K]
The triangle inequality applies.

a) 10000 < 1000 +10x
.. 1000 < 100 +x
.. 900 < x

b) 1000 < 10000 +10x
.. 100 < 1000 +x
.. -900 < x

c) 10x < 10000 +1000
.. x < 1100

x can be between 900 and 1100
