Answer:

y = -7x + 22

Step-by-step explanation:

Given

(x_1,y_1) = (4,-6)

(x_2,y_2) = (2,8)

Required

Determine the line equation

This question will be answered using linear interpolation.

This is represented as thus:

\frac{y - y_1}{x - x_1} = \frac{y_2 - y_1}{x_2 - x_1}

Substitute values for x1,x2,y1 and y2

\frac{y - (-6)}{x - 4} = \frac{8 - (-6)}{2 - 4}

\frac{y +6}{x - 4} = \frac{8 +6}{2 - 4}

\frac{y +6}{x - 4} = \frac{14}{-2}

\frac{y +6}{x - 4} =-7

Cross Multiply

y + 6 = -7(x - 4)

y + 6 = -7x + 28

Make y the subject

y = -7x + 28-6

y = -7x + 22

5y-4x=-7 what does x equal
harkovskaia [24]

Answer:

x = \frac{5y + 7}{4}

Step-by-step explanation:

5y - 4x = - 7

5y - 4x + 4x = - 7 + 4x         [adding + 4x on both sides ]

5y + 7 = - 7 + 7 + 4x            [adding 7 on both sides , - 4x + 4x = 0 ]

5y + 7 = 4x                         [ -7 + 7 = 0 ]

\frac{5y + 7}{4}  = \frac{4x}{4}                            [ dividing by 4 on both sides ]

x = \frac{5y + 7}{4}

________ analysis is the statistical process of estimating the relationship between dependent and _______ variables. A. Regressi
Sidana [21]

Answer:

A. Regression, independent

Step-by-step explanation:

Regression analysis can be regarded as a statistical methods which is been utilized in estimating the relationships that exist between a dependent variable as well as one or more independent variables. It is tools used in assessment of strength of the relationship that between variables, it could be used to model future relationship between variables.

Regression analysis posses different

variations, These are;

✓ linear

✓ nonlinear

✓multiple linear,

For linear model, this equation can be used.

Y = (a + bX + ϵ)

Where

Y =Dependent variable

a =Intercept

X= Independent variable

ϵ = Residual error

b =Slope

It should be noted that Regression

analysis is the statistical process of estimating the relationship between dependent and independent

variables.

The compound interest formula is A = P(1 + ) where P is the principal, A is the ending amount, r is the annual interest rate, m
Naddika [18.5K]

This shows that Billy will have $12, 168.25 after 12 years

<h3>Compound interest</h3>

The formula for calculating the compound interest is expressed as:

  • A = P(1+r/n)^{nt}

From the information given, the amount is expressed as;

A = 8000(1+0.035/12)^{12(12)}\\A= |\$12,168.25

This shows that Billy will have $12, 168.25 after 12 years
