Find f '(a). f(x) = 1 − 2x

Answer:

It would take 2.4 minutes

Step-by-step explanation:

Time span can never be different for the same two people. Therefore in 3 minutes, John's mother would have covered a distance of 15(3) = 45 meters. Respectively John would have covered a distance of 25(3) = 75 meters in the same time.

Distance from 'starting point' to the market: 45 m + 15 m = 60 meters,

Time that John takes to return from market, and meet with his mother

=> 15 / 25 (his speed) = 0.6,

Time it takes John to get to the market: 3 - 0.6 = 2.4 minutes

The inequality for the given statement is 10x>300.

We need to find what number is 10 times greater than 300.

In Mathematics, equations are not always about being balanced on both sides with an 'equal to' symbol. Sometimes it can be about a 'not an equal to' relationship like something is greater than the other or less than. In mathematics, inequality refers to a relationship that makes a non-equal comparison between two numbers or other mathematical expressions.

Let the unknown number be x.

Now, 10 times the number=10x

The number is 10 times greater than the 300.

That is, 10x>300

Therefore, the inequality for the given statement is 10x>300.

Answer:

Linear relationships can be compared using their initial values, or y-intercepts, and their rates of change, or slopes. Initial values can tell you which relationship started with a greater value. Comparing slopes can tell you which relationship is rising or falling faster.

Answer:

4.00

I just did the question

Answer:

The Answer is B. 4.00

Step-by-step explanation:

8x = 12

Divide both sides by 8

x = 12/8 = 3/2

2y + 10 = 22

Subtract 10 from both sides.

2y = 12

Divide both sides by 2

y = 6

6 + 3/2 = 7 1/2

Answer:

7.5 or 7½

Step-by-step explanation:

8x÷4 = 12÷4

2x = 3

x = 3/2 = 1.5

2y + 10 = 22

2y = 12

y = 6

1.5 + 6 = 7.5 = 7½

Answer: $115,012,850.8

Step-by-step explanation:

given data:

cash out amount in 1993 = $163,882,660

no of years = 7

inflation adjustment carried out on the amount would yield $163,882,660. in 1993 is equal to $115,012,850.8 1987.

This is because the Annual inflation grew over this period at a pace 4.26%.

= 4.26/100 * $163,882,660

= 0.0426 * $163,882,660 * 7

= $48,869,809.21

$163882660 – $48,869,809.21

= $$115,012,850.8

Answer:66

Step-by-step explanation:Eric had 100 at first minus 50 then the kite rose 16 more which equals 66

The number of yards of string left on spool is 34 yards.

Given that, Eric’s kite spool had 100 yards of string.

Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

At first, he let out 50 feet of string. Then, the kite rose for another 16 yards.

Now, 50+16=66 yards

So, 100-66=34 yards

Hence, the number of yards of string left on spool is 34 yards.

Answer:

C²= A²+B²

Step-by-step explanation:

A) 10²=( Base)² + 6²

(Base )²= 10² - 6²:

100-36

= 64

Base = √ 64

8

B) 17² = 8² + (Height)²

(Height) ² = 17²- 8²

= 289-64

= 225

Height = √225

= 15

C) 2.5² = Base ² + 1.5 ²

Base² = 2.5 ²- 1.5²

6.25- 2.25

= 4

Base = √4

= 2

D) 41² = Base²+ 40²

Base²= 41²- 40²

1681-1600

= 81

Base = √81

E)26²=Base² +10²

Base² = 26²- 10²

Base= √576

Answer:

  -19.3%

Step-by-step explanation:

The percentage change in a value is computed from ...

  percent change = ((new value) -(old value))/(old value) × 100%

  = (2694 -3339)/3339 × 100% = -645/3339 × 100% ≈ -19.3%

The decrease in 50 years is about 19.3%.

Answer:

Let B(a,b) be x1, y1

A(-6,1) be x2,y2

midpoint M(-3,2) be (x,y)

using midpoint formula

(x,y)= [(x1+x2)/2, (y1+y2)/2)

(-3,2) = [(a-6)/2, (b+1)/2}

comparing corresponding value

-3 = (a-6)/2                           (b+1)/2 = 2

-6= a-6                                  b+1=4

a=0                                         b=3

coordinates of B = (0,3)

-2 4/7

Step-by-step explanation:

−3 2/7 − (−5/7)

Subtracting a negative is like adding

−3 2/7 + (5/7)

Since the signs are difference we subtract and take the sign of the larger number

3 2/7 - 5/7

Borrow from the whole number

2+ 7/7 + 2/7 - 5/7

2 9/7 - 5/7
