8 0

Answer:

-8/1

Step-by-step explanation:

Perpendicular lines have opposite slopes., meaning the signs are opposite, and the numerator and denominator are flipped.

Here's another example:

If line a had a slope of 4/5, line b would have a slope of -5/4, if the lines are perpendicular.

FrozenT [24]

Answer:

d) $128.65

Step-by-step explanation:

The table format from the question can be properly expressed as :

                       Coefficients       Standard Error     t Statistic    p  value

Intercept           39.14942          22.30182             1.755436     0.109712

x                         1.792312          0.407507             4.398234    0.001339

Source            df            SS                MS             F             S_e = 29.51443

Regression      1       16850.99      16850.99   19.34446    r^2 = 0.682478

Residual          9       7839.915       871.1017

Total               10       24690.91

For a rural household with $90,000 annual income, Abby's model predicts weekly grocery expenditure of:_________.

The estimated regression equation is as follows:

Expenditure (y) = 39.15 + 1.79 x

For a rural household with $90,000 annual income; the independent variables will assume the following values

x = 50

Thus; the estimated groceries expenditure is computed from the above regression equation by replacing the values of the independent variables;

This can be expressed as:

y = 39.15 + 1.79 (50)

y = 39.15 + 89.5

y = $128.65

Find the product. (x - 7)(y - 9)
antiseptic1488 [7]
(x - 7)(y - 9)

x*(y - 9) - 7*(y - 9)

x*y - x*9 - 7*y -7*(-9)

xy - 9x - 7y + 63

That's the product.

I want a way to solve this question​
spin [16.1K]

Answer:

the slope is the coefficient of x= ⅕

intercept in x-axis → y=0 → f(x) = 0 → ⅕x -5 = 0 → ⅕x = 5 →x = 25 (25,0)

intercept in y axis : x= 0 → f(x) = ⅕(0) -5 = -5
