Answer:

C. 16 + 1/12

Step-by-step explanation:

5 + 1/2 = 11/2 = 66/12

6 + 1/3 = 19/3 = 76/12

4 + 1/4 = 17/4 = 51/12

66/12 + 76/12 + 51/12 = 193/12

193/12 = 16 + 1/12

Could someone please help me with this problem?

natima [27]

Answer:

C

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (4, 9) and (x₂, y₂ ) = (12, 20)

m = $\frac{20-9}{12-4}$ = $\frac{11}{8}$ → C

HELP!!!! Choose the correct answer. Which expression, when evaluated,

blagie [28]

We will check each options and verify it

(a)

$18-2m$

we can plug m=2

$18-2\times 2$

$18-4$

$14$

so, this is FALSE

(b)

$7x-\frac{x}{3} >19$

we can plug x=3

$7\times 3-\frac{3}{3} >19$

$21-1 >19$

$20 >19$

so, this is TRUE

(c)

$6x-1>4x+5$

we can plug x=3

$6\times 3-1>4\times 3+5$

$18-1>12+5$

$17>17$

so, this is FALSE

(d)

$2x^2-3x+1$

now, we can plug x=2

$2(2)^2-3(2)+1$

$8-6+1$

$3$

So, this is FALSE
