Answer:

Step-by-step explanation:

9 - 4x > = 5 or 4(-1 + x) - 6 > = 2

-4x > = 5 - 9 -4 + 4x - 6 > = 2

-4x > = -4 4x - 10 > = 2

x < = -4/-4 4x > = 2 + 10

x < = 1 4x > = 12

x > = 12/4

x > = 3

answer is : B

The ordered pairs in the table below represent a linear function.

Lilit [14]

Answer:

The slope is 2

Step-by-step explanation:

Given

x y

2 3

5 9

Required

Determine the slope

First, we have:

$(x_1,y_1) = (2,3)$

$(x_2,y_2) = (5,9)$

The slope is then calculated as:

$m = \frac{y_2 - y_1}{x_2 - x_1}$

This gives:

$m = \frac{9-3}{5-2}$

$m = \frac{6}{3}$

$m =2$

<em>Hence, the slope is 2.</em>

Mr. Alvarado needs 15 1/8 pounds of chicken feed to fill his feeder. He has one bag of chicken feed that weighs 3 1/2 pounds and

Crazy boy [7]

Answer:

B: 8 7/8 Lbs

Step-by-step explanation:

answer = $15\frac{1}{8} -3\frac{1}{2} -2\frac{3}{4}$

step 1 find a common denominator

common denominator - 8

* apply *

$\frac{1^*^1}{8^*^8} =\frac{1}{8} \\\\\frac{1^*^4}{2^*^4} =\frac{4}{8} \\\\\frac{3^*^2}{4^*^2} =\frac{6}{8}$

now we have

$15\frac{1}{8} -3\frac{4}{8} -2\frac{6}{8}$

step 2 make each fraction a improper fraction

We can do this my multiplying the big number by the denominator and adding that to the numerator.

$15*8=120\\120+1=121\\\frac{121}{8} \\\\3*8=24\\24+4=28\\\frac{28}{8} \\\\2*8=16\\16+6=22\\\frac{22}{8}$

now we have

$\frac{121}{8} -\frac{28}{8} -\frac{22}{8}$

Now we can subtract

remember when subtracting fractions you only subtract the numerators. ( so we keep the denominator as 8 )

so 121 - 28 - 22 = 71

so the answer is $\frac{71}{8}$

finally we want to change the answer back into a mixed fraction

To do this we divided 71 and 8

8 can go into 71 8 times

8 * 8 = 64

71 - 64 = 7

We're left with $8\frac{7}{8}$
