Answer:
Part 1: [ -4 = -8 ]
Part 2: Inconsistent
Step-by-step explanation:
Part 1
1. Move all terms that don't contain x to the right side:
3x - 6y+6y = -12+6y
= 3x = -12 + 6y
2. Isolate x:
[tex]\frac{3x}{3} = \frac{-12+6y}{3}[/tex]
x = -4 + 2y
3. Substitute the new expression into the original:
-4 + 2y - 2y = -8
4. Simplify:
-4 + 0 = -8
[ -4 = -8 ]
Part 2
The two solutions are not equal in value, so, we can conclude that the system of equations has no solution, or is inconsistent.

She calculates two regression models. which is true? the linear model better represents the situation because the amount she owes is decreasing by about the same amount every 6 months. the linear model better represents the situation because according to the exponential model, the repayment amount will never be 0. the exponential model better represents the situation because the amount she owes decreases by about the same amount every 6 months. the exponential model better represents the situation because according to the linear model, the repayment amount will eventually be negative.
The answer is A.thus, this is a linear model. To check,you can see visually that the points are more fitted to the line than the curve.
What is linear regression?Linear regression is the most basic and commonly used predictive analysis. Regression estimates are used to describe data and to explain the relationship.
The difference between the linear model and the exponential model is the degree of difference of consecutive points. If their difference is constant, then it is more appropriate for the linear model. If their difference is increasing at a very fast rate, then that follows an exponential model. With that being said, let's look at the differences at every 6 month-intervals.
2700-2110 = 590
2110-1500 = 610
1500-870 = 630
870-220 = 650
Their differences are about the same having a mean of 620. Thus, this is a linear model. To check,you can see visually that the points are more fitted to the line than the curve. The answer is A.

Step-by-step explanation:
The area of a circle is 49 pi cm^2 what is the radius of a circle
Answer:
The radius is 7 cm
Step-by-step explanation:
We know the area of a circle is given by
A = pi r^2
49 pi = pi r^2
Divide each side by pi
49 = r^2
Take the square root of each side
sqrt(49) = sqrt(r^2)
7 = r
The radius is 7 cm
Answer:
radius = 7 cm
Step-by-step explanation:
the area (A) of a circle is calculated as
A = πr² ( r is the radius )
given A = 49π , then
πr² = 49π ( divide both sides by π )
r² = 49 ( take square root of both sides )
r = [tex]\sqrt{49}[/tex] = 7
The three sides of a triangle are (x+5)cm ,(2x+4)cm and (2x-3)cm .
a.find the perimeter of the triangle
b. if x =10, find the perimeter of the traingle.
Hey ! there
Answer:
a. Perimeter = ( 5x + 6 ) cmb. Perimeter when x is equal to 10 = 56 cmStep-by-step explanation:
In this question we are given with three sides of a triangle that are as follows ,
( x + 5 ) cm ( 2x + 4 ) cm ( 2x - 3 ) cmAnd we are asked to :
a. find perimeter of triangle. b. find perimeter if x is equal to 10 .We know that for finding perimeter of any shape we must have to add all the sides of the shape or ,
[tex] \qquad \: \underline{\boxed{\frak{Perimeter = Sum \: of \: all \: sides}}}[/tex]
Solution : -
( a )
Now adding all the three sides of triangle to find the perimeter .
[tex] \hookrightarrow \quad \: ( x + 5 ) + ( 2 x + 4 ) + ( 2x - 3 ) [/tex]
[tex] \hookrightarrow \quad \: \: x + 5 + 2x + 4 + 2x - 3[/tex]
Combining like terms :
[tex] \hookrightarrow \quad \:x + 2x + 2x + 5 + 4 - 3[/tex]
Now , solving :
[tex] \hookrightarrow \quad \: \red{\underline{ \boxed{ \frak{(5x + 6) \: cm}}}}[/tex]
Therefore , perimeter of triangle is 5x + 6 centimetres .( b )
Now , we are finding perimeter of triangle when value of x is 10 . So substituting value of x in given sides of triangle ,
First Side :
x + 510 + 515 cmSecond Side :
2x + 42 ( 10 ) + 420 + 424 cmThird Side :
2x - 32 ( 10 ) - 320 - 317So , all the sides are 15 cm , 24 cm and 17 cm .
Now , adding all these to find perimeter .
[tex] \hookrightarrow \qquad \: 15 + 24 + 17[/tex]
[tex]\hookrightarrow \qquad \: 39 + 17[/tex]
[tex]\hookrightarrow \qquad \: \red{\underline{\boxed{\frak{56 \: cm}}}}[/tex]
Therefore , perimeter of triangle when value of x is 10 cm is 56 cm .Alternative Solution : -
As above we have find the perimeter of triangle in term of x that is ( 5x + 6 ) cm. So we can put value of x as 10 in this to get perimeter. So ,
5x + 65 ( 10 ) + 650 + 656 cmTherefore, perimeter of triangle is 56 cm .

Suppose you carry out a significance test of h0: μ = 8 versus ha: μ > 8 based on sample size n = 25 and obtain t = 2. 15. Find the p-value for this test. What conclusion can you draw at the 5% significance level? explain.
a the p-value is 0. 2. We reject h0 at the 5% significance level because the p-value 0. 02 is less than 0. 5.
b the p-value is 0. 2. We fail to reject h0 at the 5% significance level because the p-value 0. 02 is less than 0. 5.
c the p-value is 0. 48. We reject h0 at the 5% significance level because the p-value 0. 48 is greater than 0. 5.
d the p-value is 0. 48. We fail to reject h0 at the 5% significance level because the p-value 0. 48 is greater than 0. 5.
e the p-value is 0. 52. We fail to reject h0 at the 5% significance level because the p-value 0. 52 is greater than 0. 5
Using a t-distribution calculator and finding the p-value, the correct option regarding the conclusion is given by:
a) the p-value is 0.02. We reject h0 at the 5% significance level because the p-value 0.02 is less than 0.05.

The equation of a circle is shown. What is the radius?
----------------------------------------------------------------------------------
Equation of a circle
[tex](x-a)^2+(y-b)^2=r^2[/tex]
(where (a, b) is the center and r is the radius)
Given equation:
[tex]x^2+y^2-10x+8y+16=0[/tex]
Collect like terms:
[tex]\implies x^2-10x+y^2+8y+16=0[/tex]
Subtract 16 from both sides:
[tex]\implies x^2-10x+y^2+8y=-16[/tex]
Complete the square for both variables.
Add 25 to both sides for x. Add 16 to both sides for y.
[tex]\implies x^2-10x+25+y^2+8y+16=-16+25+16[/tex]
[tex]\implies (x^2-10x+25)+(y^2+8y+16)=25[/tex]
Factor the two variables:
[tex]\implies (x-5)^2+(y+4)^2=25[/tex]
Therefore:
center of the circle = (5, -4)radius of the circle = √25 = 5
