Answer:
3y+4x=5
Step-by-step explanation:
step 1
Find the slope
we have
(–7, 11) and (8, –9)
m=(-9-11)/(8+7)
m=-20/15
m=-4/3
step 2
Find the equation of the line into point slope form
we have
m=-4/3
point (-7,11)
substitute
y-11=-(4/3)(x+7) ----> equation of the line into point slope form
Multiply by 3 both sides
3y-33=-4(x+7)
3y-33=-4x-28
3y+4x=33-28
3y+4x=5 -----> equation of the line into standard form
14 is 8% of what number
14 is 8% of the number 175, and 16% of 175 is equal to 28.
To find a number that 14 is 8% of, we can set up the equation:
14 = 0.08 × x
Dividing both sides by 0.08:
14 / 0.08 = x
x = 175
Therefore, 14 is 8% of 175.
To find 16% of 175, we can multiply 175 by 0.16:
16% of 175
= 0.16 × 175
= 28.

The cost of a ticket t to a concert with a 3% sales tax can be represented by the expression t + 0.03t. Simplify the expression. Then determine the total cost after the sales tax if the original price is $72.
The simplified expression for the cost of a concert ticket with a 3% sales tax is t(1.03). For an original ticket price of $72, the total cost after adding the sales tax is $74.16.
Explanation:The cost of a ticket t to a concert with a 3% sales tax can be simplified by first expressing the total cost as a single expression. Simplify the expression t + 0.03t by factoring out t, which gives us t(1 + 0.03) or t(1.03). This shows that the total cost is 103% of the original ticket price.
To find the total cost after the sales tax for a ticket initially priced at $72, simply multiply the original price by 1.03:
$72 × 1.03 = $74.16
Thus, the total cost of the concert ticket after applying the 3% sales tax is $74.16.

6 + 3 1/2
(6 x 3) + (6 x 2)
(6 x 1) + (6 x 3)
(6 x 3) + (6 x 1/2)
The area of a rectangular rug given the dimensions 6ft by 3.5ft can be calculated by multiplying these measurements. The correct mathematical expression representing this concept is 6 x 3.5. When performed, it results in an area of 21 square feet.
Explanation:To find the area of a rectangular rug, you need to multiply the rug's length by its width. Given that the rug is 6 ft on one side and 3.5 ft on the other side, you would multiply 6 ft by 3.5 ft.
So, the correct mathematical expression to find the area of the rug is 6 x 3.5.
To perform the multiplication, you would do:
Multiply the whole number part of 3.5 (which is 3) by 6, which gives you 18.Multiply the fractional part of 3.5 (which is 0.5) by 6, which gives you 3.Add those two results together (18 + 3) to get the total area of the rug: 21 square feet.Learn more about Area of a Rectangle here:https://brainly.com/question/15218510

An organisation has a monthly budget of x dollars. Every month $2,070 is spent on salaries. One-fourth of the remaining budget is spent on monthly activities.
Which function can be used to find the amount in dollars spent on monthly activities?
Please help. Not hard I just don't understand. Thanks
Answer:D
Step-by-step explanation:
X is the budget
So you already know you have to subtract 2070 for salaries then 1/4 of that that is the answer the only way that can be expressed is by D
The function that can be used to find the amount in dollars spent on monthly activities is D. f(x) = x-2070 / 4
Monthly budget of the organization = x
Amount spent on salaries = 2070
Amount spent on monthly activities will be calculated thus:
= 1/4 × (x - 2070)
= (x - 2070) /4
Therefore, for the information and the calculation given above, it can be inferred that the correct option that suits the expression will be D.

6 times the sum of a number t and 5 is s
The verbal statement '6 times the sum of a number t and 5 is s' is translated into the algebraic equation 6(t + 5) = s, which is a linear equation used to solve for either t or s.
Explanation:The student's question involves creating an algebraic equation from a verbal statement. In this case, the expression '6 times the sum of a number t and 5 is s' can be translated into an algebraic equation. To do so, we first represent the sum of the number t and 5 as (t + 5). We then multiply this sum by 6 to represent '6 times the sum', which gives us the equation 6(t + 5) = s.
This equation allows us to solve for the number t when s is known, or vice versa. It is a basic linear equation that can be used in various mathematical problems to determine the value of s given a specific t, or to find t when s is known.
