Mathematics
1 answer:
Leto [7]3 years ago
4 0

Answer:

The given equation having only one solution i.e., "w = 3". A further explanation is provided below.

Step-by-step explanation:

The given equation is:

⇒ 9(w-9)-2=-7w+7(w-8)

By opening the brackets, we get

⇒ 9w-81-2=-7w+7w-56

⇒ 9w-83=-56

On adding "83" both sides, we get

⇒ 9w-83+83=-56+83

⇒                 9w=27

⇒                   w=\frac{27}{9}

⇒                       =3

Sal walks 14 km in 4 h

Sal walks 3.5 km in 1 h

Step-by-step explanation:

Given:

Distance represented by Y axis in kilometer.

Time represented by X axis in hour,

The graph of line is showing distance walked. And the two points are (1, 3.5) and (4, 14).

In plotting of points the first coordinate is always the X coordinate that is time in hour here, and the second coordinate is always the Y coordinate that is distance in km.

Therefore, the given below two options are correct

Y= 2x-1 is a tangent to y=x^2. Name the point of tangency,
lubasha [3.4K]

Answer:

Point of tangency is x=1 or (1,1)

Step-by-step explanation:

You don't really need to use Calculus here. You can just set each equation to each other and solve for x (the point of tangency):

x^2=2x-1

x^2-2x+1=0

(x-1)(x-1)=0

x=1

Therefore, the point of tangency is x=1 or (1,1)

a football game has 13 fans for every 7 players. if there are 540 more fans than players. how many players are there
Mademuasel [1]
For this problem, we can set up an equation. We will represent how many players there are as x. This is what our equation would look like:

13/7 = 540/x

Now we can multiply both sides by x:

13x/7 = 540

Now we multiply both sides by 7:

13x = 91

Now we simplify and divide 13 from both sides to get our final answer:

x = 7

Write the 2-digit number that matches the club
Temka [501]

Answer:

91

Step-by-step explanation:

for a 2-digit number the tens digit (x) is 8 more than the ones digit (y) and no number is zero

=> x = y+8

x < 10

y > 0

y = 1 and x = 1 + 8 =9

the 2-digit is 91
