-2x - 6y = -24<br> X-8y = -10

Debora [2.8K]

Answer:

x = -26 and y = -2

I hope this is the answer you are looking for

Step-by-step explanation:

x-8y = -10 => add 8y to both sides

+8y = +8y

x = -10+8y

-2(-10+8y) -6y = -24 => intersect what you got into the first equation

20-16y-6y = -24 => Distribute the -2

20-22y = -24 => subtract 20 in both sides

-20 = -20

-22y = -44 => divided by -22 in both sides

/-22 = /-22

y = -2

x-8(-2) =-10 => intersect the y into the other equation

x+16 = -10 => multiply -8*-2

-16 = -16

x = -26 => subtract 16 in both sides.

4. This is a

bixtya [17]

Answer:

Step-by-step explanation:

4). This is an exponential function.

5). Let the equation of this function is,

f(x) = a(b)ˣ

Since, two points (-1, 4) and (0, 6) are lying on the graph of the function,

For (-1, 4),

4 = a(b)⁻¹

4 = $\frac{a}{b}$ --------(1)

For (0, 6),

6 = a(b)⁰

a = 6

From equation (1),

4 = $\frac{6}{b}$

b = $\frac{6}{4}$ = 1.5

Therefore, equation of the function will be,

f(x) = 6(1.5)ˣ

6). Now the value of f(-4) will be,

f(-4) = 6(1.5)⁻⁴

= 1.185
