Karolina [17]

we are given

-3 x 2(4-18) + 8 =

Firstly , we will solve inside parenthesis

$-3 *2(4-18) + 8 =$

$-3 *2*-14 + 8 =$

now, we can multiply

$-6*-14 + 8 =$

$84 + 8 =$

$=92$ ............Answer

The equation of the parabola with vertex (-5,3), with axis parallel to the x-axis, opening to the right and with x-intercept x =

lutik1710 [3]

Answer:

$x=1(y-3)^2-5$

Step-by-step explanation:

we need to find the equation of the parabola with vertex (-5,3), with axis parallel to the x-axis.

general equation of horizontal parabola is

$x=a(y-k)^2+h$

where (h,k) is the vertex

(-5,3) is the vertex. h=-5 and k=3. plug in the values in the general equation

$x=a(y-3)^2-5$

Now find out the value of 'a' using x intercept (4,0)

$4=a(0-3)^2-5$

$4=a(-3)^2-5$

$4=9a-5$

Add 5 on both sides

$9=9a$

a=1

the equation becomes

$x=1(y-3)^2-5$

Answer:

The number of units decreased by $8.7\%$ .

Step-by-step explanation:

Initially, 470 units were sold. The following 429 units were sold, meaning this was $470-429=41$ less units than last year. Thus, the number of units sold decreased and the percent of decrease is:

$\frac{41}{470}\approx 8.7\%$
