-25 15/19 + 9/1

get a common denominator of 19

they multiplied 9/1 * 19/19 = 171/19

-25 15/19 + 171/19 =

change the mixed number to an improper fraction

(19* 25 +15)/19 = 490/19

-490/19 + 171/19 =

add together

-319/19

now convert the improper fraction back to a mixed number

19* 16 =304  319-304=15

-319/19 =-16 15/19

Which relation is a function? A) y2 + 3x = 9 B) y(2x + 4y) = 8 C) x2 + 7x = 7y2 D) yx = x3 + 4x2 + 4x
Maslowich
The first one is a parabola opening sideways so it will not pass the vertical line test
B   not a function as it can be arranged in form  x =  expression in y^2 so it would be a one-to-many relation.

D is a function  because its a parabola which open upwards so it will pass the vertical line test

The sum of two consecutive odd integers is 236. What is the smaller integer
jolli1 [7]

So the answer would be 117 since it is the smaller integer out of the 2.

Hope this helped! :)

Write the equation of line that passes through (-1,3) and (-5,-3)
Black_prince [1.1K]

Answer:

y =  \frac{3}{2} x + 4 \frac{1}{2}

Step-by-step explanation:

y=mx+c

where m is the gradient and c is the y-intercept of the line

Let's find the gradient of the line first.

gradient =  \frac{y1 - y2}{x1 - x2}

Using the above formula,

gradient \: of \: line \\  =  \frac{3 - ( - 3)}{ - 1 - ( - 5)}  \\  =  \frac{3 + 3}{5 - 1}  \\  =  \frac{6}{4}  \\  =  \frac{3}{2}

Subst. the gradient into m:

y =  \frac{3}{2} x + c

Now, find the value of c by substituting a coordinate into the above equation.

when x=-1, y=3,

3 =  \frac{3}{2} ( - 1) + c \\ 3 =  -\frac{3}{2}  + c \\ c = 3 +  \frac{3}{2}  \\ c = 4 \frac{1}{2}

Therefore the equation of the line is

y =  \frac{3}{2} x +  4\frac{1}{2}

8_murik_8 [283]

Answer:

$179.76

Step-by-step explanation:

We can calculate the total cost as follows.  The 1.00 represents the before-tax cost of the dehumidifier and the 0.0575 the 5.75% sales tax:

Total cost of dehumidifier = (1.00+0.0575)($169.99) = $179.76 (to the nearest
