If f(x)= mx+ c , f (1)=5 and f(-2)=-1

taurus [48]

Answer:

$y = 2x + 3$

Step-by-step explanation:

We can find the slope.

$\frac{ 5 + 1}{1 + 2 } = 2$

so m is 2

$y = 2x + c$

Plug one the equations in to find c.

$- 1 = 2( - 2) + c$

$- 1 = - 4 + c$

$3 = c$

so the equation is

$y = 2x + 3$

What is the sum of 1/9, 2/3, and 5/18?<br> A. 19/18<br> B.4/15<br> C. 12/9<br> D. 8/20

kari74 [83]

Answer:

19/18

Step-by-step explanation:

The GCF of 9, 3, and 18 is 18.

Each denominator must be multiplied to 18, and as a result what you multiply in the denominator MUST be multiplied in the numerator.

9 * 2 = 18

1 * 2 = 2

2/18

3 * 6 = 18

6 * 2 = 12

12/18

5/18

Add all three fractions together:

12/18 + 5/18 + 2/18 = 19/18
