<h3>Further explanation</h3>One variable linear equation is an equation that has a variable and the exponent number is one.
Can be stated in the form:
or
ax + b = c, where a, b, and c are constants, x is a variable
We complete the task :
A nutritionist planning a diet for a football player wants him to consume 3,500 Calories and 725 grams of food daily. Calories from fat and protein will be 45% of the total Calories. There are 4, 4, and 9 Calories per gram for protein, carbohydrates, and fat, respectively. How many daily grams of protein will the diet include?
- 243.75
- 481.25
- 123.75
- 120
Calories from fat and protein will be 45% (0.45) of the total Calories
Calories from fat and protein = 0.45 x 3500 = 1575 calories
Calories from carbohydrates = 3500 - 1575 = 1925 calories
So mass for carbohydrates = 1925 : 4(4 calories/gram) = 481.25 grams
Then mass for fat and protein = 725 - 481.25 = 243.75 grams
We can make equation for fat and protein
1. 4 calories. mass of protein(p) + 9 calories . mass of fat(f) = 1575 calories
2. mass of protein(p) + mass of fat(f) = 243.75
we can simplify :
1. 4p+9f = 1575
2. p + f = 243.75 ⇒ f = 243.75 - p
we substitute equation 2 into equation 1 :
4p + 9(243.75-p) = 1575
4p + 2193.75-9p=1575
-5p = -618.75
p = 123.75

Answer:
The equations represent the line that is parallel to 3x - 4y = 7 and pass through the point (-4,-2) are:
Step-by-step explanation:
The slope-intercept form of the line equation
where
- m is the slope
- b is the y-intercept
Given the line
3x - 4y = 7
writing in the slope-intercept form
4y = 3x - 7
dividing both sides by 4
4y/4 = 3/4x - 7/4
y = 3/4x - 7/4
Now, comparing with the slope-intercept form of the line equation
y = 3/4x - 7/4
The slope of the line m = 3/4
We know that parallel lines have the same slopes.
Therefore, the slope of the parallel line is: 3/4
now we have,
The point (-4, -2)
The slope m of parallel line = 3/4
Given the point-slope form of the line equation
where m is the slope of the line and (x₁, y₁) is the point
substituting (-4, -2) and m = 3/4 in the point-slope form of line equation
Thus, the equation in the point-slope form of the line equation is:
Simplifying the equation
Subtract 3 from both sides
Multiplying the equation by 4
Therefore, the equations represent the line that is parallel to 3x - 4y = 7 and pass through the point (-4,-2) are:
