Answer:

y = -53/2, x = -17

Step-by-step explanation:

1/2x + 3/2 = -7

-3x +2y = -2

Isolate X for 1/2x + 3/2 = -7

X = -17

Substitute X = -17

-3(-17) + 2y = -2

Isolate Y for -3 (-17) + 2y = -2

Y = -53/2

Answer:

x>10

Step-by-step explanation:

1/2*x-3-(2)>0

Step by step solution :

Step 1 :

1

Simplify —

2

Equation at the end of step 1 :

1

((— • x) - 3) - 2 > 0

2

Step 2 :

Rewriting the whole as an Equivalent Fraction :

2.1 Subtracting a whole from a fraction

Rewrite the whole as a fraction using 2 as the denominator :

3 3 • 2

3 = — = —————

1 2

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

x - (3 • 2) x - 6

——————————— = —————

2 2

Equation at the end of step 2 :

(x - 6)

——————— - 2 > 0

2

Step 3 :

Rewriting the whole as an Equivalent Fraction :

3.1 Subtracting a whole from a fraction

Rewrite the whole as a fraction using 2 as the denominator :

2 2 • 2

2 = — = —————

1 2

Adding fractions that have a common denominator :

3.2 Adding up the two equivalent fractions

(x-6) - (2 • 2) x - 10

——————————————— = ——————

2 2

Equation at the end of step 3 :

x - 10

—————— > 0

2

Step 4 :

4.1 Multiply both sides by 2

Solve Basic Inequality :

4.2 Add 10 to both sides

x > 10

the amount of food a dog should eat depends on the weight of the dog. 1. identify the independent and dependent variables in thi
fomenos

Here, we are required to identify the dependent and independent variables, the dependency relationship in the situation.

  1. The independent and dependent variables are the weight of the dog and the amount of food it should respectively.
  2. The dependency relationship is thus; The amount of food a dog should eat is a function of the weight of the dog
  3. The dependency relationship using the function notation is; f(x) = {function of x}.

  • The independent variable in this situation is the weight of the dog while the amount of food the dog should eat is the dependent variable. The above is evident from the statement; <em>T</em><em>he amount of food a dog should eat depends on the weight of the </em><em>dog</em><em>.</em>

  • <em>According</em><em> </em><em>to </em><em>the </em><em>premise</em><em> </em><em>given </em><em>in </em><em>the </em>question, it is evident that the dependency relationship is;. The amount of food a dog should eat is a function of the weight of the dog

  • The dependency relationship can be written mathematically using the function notation as;. f(x) = {function of x}.
