Answer:

Value of a = 8

Value of b = 2

Value of c = - 10

Step-by-step explanation:

(2x + 3)(4x - 5)

=  > 2x(4x - 5) + 3(4x - 5)

=  > 8 {x}^{2}  - 10x + 12x - 15

=  > 8 {x}^{2}  + 2x - 10

As per the general form of a quadratic eqn. a {x}^{2}  + bx + c

Value of a = 8

Value of b = 2

Value of c = - 10

F(x)=x+7 <br><br> If you know that the domain is {-10,-5} then the range must be {__,__}
kvasek [131]

Answer:

[-3, 2]

Step-by-step explanation:

Plug in the x values into the equation and evaluate...

f(-10) = -10 + 7 = -3

f(-5) = -5 + 7 = 2

Since f(x) is a continuous line, the range with constantly increase as x increases, so we know that this is the range over that domain.

How many intersections are there of the graphs of the equations below?
kipiarov [429]

Answer:

<u>The number of intersections = ∞</u>

Step-by-step explanation:

Given the system of equations:

0.5 x + 5y = 6

3x + 30y = 36

By multiplying the first equation by 6

∴ 6 (0.5 x + 5y) = 6 * 6

∴ 3x + 30y = 36

So, Those equations are "Dependent", because they are really the same equation, just multiplied the first equation by 6.

So, the two equations are identical

Therefore: <u>They have infinity number of solutions.</u>

<u>See the attached figure.</u>

0.5 x + 5y = 6 ⇒ in black color

3x + 30y = 36 ⇒ in red color
