Write an equation, in slope-intercept form, that passes through point (-4,- 3) with slope 3.
Answer:
y=3x+9
Step-by-step explanation:
Slope intercept form: y=mx + b
m= slope
b= y-intercept
-Plugin the point
-3=3(-4)+b
-3(+12) = -12 + b(+ 12)
9=b
y = 3x + 9
The Wells family drinks 8.5 gallons of milk per week. The McDonald family drinks 1.1 gallons of milk each day. What is the difference, in liters, between the amounts of milk the families will drink in one week? (1 gallon is approximately 3.8 liters)

Which is simplified form of the expression (6-2•65)-3
Answer:Answer:
The simplified form of this is 6^-9
Step-by-step explatnation
In order to find this, we first complete the operation inside the parenthesis. In this case, since it is multiplication, we add the exponents.
6^-2 x 6^5 = 6^3
Now that we have the simplified inside we multiply exponents using the parenthesis.
(6^3)^-3 = 6^-9

Answer:
u=50/11
Step-by-step explanation:
cross multiply and divide on both sides
Answer:
u = [tex]\frac{50}{11}[/tex]
Step-by-step explanation:
Given
[tex]\frac{u}{10}[/tex] = [tex]\frac{5}{11}[/tex] ( cross- multiply )
11u = 50 ( divide both sides by 11 )
u = [tex]\frac{50}{11}[/tex]

The perimeter of a fence must be no larger than 500 feet in length. The longer side of the fence must be 10 feet more than twice the length of the shorter side. Write and solve and inequality to determine the maximum length of the shorter side of the fence.
Answer:
The shortest side of the fence can have a maximum length of 80 feet
Step-by-step explanation:
Inequalities
To solve the problem, we use the following variables:
x=length of the longer side
y=length of the sorter side
The perimeter of a rectangle is calculated as:
P = 2x + 2y
The perimeter of the fence must be no larger than 500 feet. This condition can be written as:
[tex]2x + 2y \le 500[/tex]
The second condition states the longer side of the fence must be 10 feet more than twice the length of the shorter side.
This can be expressed as:
x = 10 + 2y
Substituting into the inequality:
[tex]2(10 + 2y) + 2y \le 500[/tex]
This is the inequality needed to determine the maximum length of the shorter side of the fence.
Operating:
[tex]20 + 4y + 2y \le 500[/tex]
Simplifying:
[tex]20 + 6y \le 500[/tex]
Subtracting 20:
[tex]6y \le 500 - 20[/tex]
[tex]6y \le 480[/tex]
Solving:
[tex]y \le 480 / 6[/tex]
[tex]y \le 80[/tex]
The shortest side of the fence can have a maximum length of 80 feet
