Im not for sure.. but I think it would be something like 3,9
Answer:
We rearrange the first equation into y = 8x - 42 and we substitute it in to get
-4x - 6 = 8x - 42 so 12x = 36 so
x = 3 and y = -18

The circumference of a circle is 18.41 feet. What is the approximate length of the radius?
2.8 feet
2.9 feet
3.0 feet
Answer:
2.9 feet
Step-by-step explanation:
The radius of Circle A is 6 mm. The radius of Circle B is 4 mm greater than the radius of Circle A. The radius of Circle C is 2 mm greater than the radius of Circle B. The radius of Circle D is 3 mm less than the radius of Circle C. What is the area of each circle? How many times greater than the area of Circle A is the area of Circle D
Answer:
Area of circle A =113.14 mm²
Area of circle b = 314.29 mm²
Area of circle C = 452.57 mm²
Area of circle A = 254.57 mm²
2.25 times
Step-by-step explanation:
Area of a circle = nr²
where n = 22/7
r = radius
Circle A's radius = 6mm
Circle B's radius = 6mm + 4mm = 10mm
Circle C's radius = 10mm + 2mm = 12mm
Circle D's radius = 12mm - 3mm = 9mm
Area of circle A = (22/7) x 6² = 113.14 mm²
Area of circle b = (22/7) x 10² = 314.29 mm²
Area of circle C = (22/7) x 12² = 452.57 mm²
Area of circle A = (22/7) x 9² = 254.57 mm²
Number of times the area of circle D is greater than that circle A = Area of circle D / Area of circle A
254.57 mm² / 113.14 mm² = 2.25 times

What is the solution to the system of equations?
x = -4y
3x + 2y = 20
Answer:
(x, y) = (8, -2)
Step-by-step explanation:
Substitute:
3(-4y) + 2y = 20
-12y + 2y = 20
-10y = 20
y = -2
x = -4(-2) = 8

Draw a conclusion is the statment below always, sometimes, or never true ? Bive at least two examples to support your reasoning. The lcm of two numbers is the product of the two number discuss your conclusion with a partner
Answer:
Sometimes
Step-by-step explanation:
Example 1:
Take two numbers as [tex]7,8[/tex]
LCM of [tex]7,8=7(8)=56[/tex]
In this case, the lcm of two numbers is equal to the product of the two numbers.
Example 2:
Take two numbers as [tex]6,3[/tex]
[tex]6=3(2)[/tex]
So,
LCM of [tex]6,3=3(2)=6[/tex]
In this case, the lcm of two numbers is not equal to the product of the two numbers.
Therefore,
Sometimes, the lcm of two numbers is equal to the product of the two numbers.
A city receives 2 inches of snowfall every 3 hours. Write and graph a function that describes the relationship. How long does it take to receive 1 foot of snow? Use x for the independent variable and y for the dependent variable.
Answer:
To receive 1 foot of snow it will take about 18 hours.
Step-by-step explanation:
Given that a city receives 2 inches of snowfall every 3 hours, to write and graph a function that describes the relationship and determine how long does it take to receive 1 foot of snow, the following calculation must be performed:
1 foot = 12 inches
(12/2) x 3 = X
6 x 3 = X
18 = X
Thus, to receive 1 foot of snow it will take about 18 hours.

What is the slope of line that passes through the points (-3,8) and (1,32)?
Answer:
6
Step-by-step explanation:
use the formula of slopes
[tex] = \frac{y2 - y1}{x2 - x1} \\ = \frac{32 - 8}{1 - ( - 3)} \\ = \frac{24}{4} \\ = 6[/tex]
Answer:
[tex]\frac{31 }{11 }[/tex]
Step-by-step explanation:
The formula to solve this is: [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]. In this case, the expression would be: [tex]\frac{32 -1 }{8 -(-3) }[/tex] or [tex]\frac{32 -1 }{8 +3 }[/tex]. This is also [tex]\frac{31 }{11 }[/tex].
Hope it helps and is correct!
