Solve for x. ←2x+6 X+9 x = [?]

Mathematics
1 answer:
Scorpion4ik [409]2 years ago
4 0

Answer:

3

Step-by-step explanation:

A simple way to solve this is by substituting, we start with trying 1 for x, 2+6=8, and 1+9=10. Because the two values are different, that means 1 is the incorrect value. We can try 2, 4+6=10, and 2+9=11, once again inequivalent. We finally try 3, and 6+6=12 and 3+9=12 meaning x must be 3

Solve each equation by graphing. Round to the nearest tenth.
arlik [135]

B

rearrange into standard form : ax² + bx + c = 0 (a≠ 0)

2x² - 3x - 2 = 0

(x - 2)(2x + 1) = 0 ( equate each factor to zero and solve for x )

x - 2 = 0 ⇒ x = 2

2x + 1 = 0 ⇒ x = - 0.5

The number of people, N, that Denis can invite to his party is dependent on the amount of money, x, in dollars,
gulaghasi [49]

Answer:

N(h) = 2h + 6

Step-by-step explanation:

A model of the number of people that Denis can invite to his party:

N(x) = x/25.............(1)

Where x = amount of money saved

Amount of money saved can be modeled by the equation:

M(h) = 50h + 150...........(2)

In the above model, h = number of overtime hours

M(h) = amount of money saved = x

Therefore equation (1) can be re - written as:

N(x) = M(h)/25.................................(3)

Substituting equation (2) into equation (3)

N(h) = \frac{50h + 150}{25} \\N(h) = \frac{50h}{25} + \frac{150}{25} \\N(h) = 2h + 6

Find an explicit expression that models the number of people that Denis can invite to his party if he worked h  overtime hours this week can be expressed as:

N(h) = 2h + 6

Suppose a triangle has sides a, b, and c let theta be the angle opposite the side of length a. If cos theta < 0 what must be
LenaWriter [7]

Using the cosine rule, a² =  b² +  c² -2 bc cos θSImplifying the equation in terms of cos  theta,
cos(θ) = (a² + c² - b²)/(2bc) 
(a² + c² - b²)/(2bc) > 0 a² + c² - b² > 0 
assuming b and c are non zeros, the resulting inequality should be
a² + c² > b²
