Alice wanted to solve for x by getting rid if the +8. explain and correct Alice error

ra1l [238]

Answer: The value of x will be 2.

Step-by-step explanation:

To calculate the value of 'x' or solve for x, we need to isolate x from 8.

In the equation, 8 is in addition with 'x' so for isolating it, we need to apply the reverse operation of addition.

Reverse operation of addition is subtraction.

We need to subtract 8 from both sides of the equation, we get:

$x+8-8=10-8\\\\x=2$

By doing this, we get the value of 'x' as 2.

Error done by Alice was that she added 8 and it did not led to the isolation of 'x'.

hich uses the high-low method to analyze cost behavior, has determined that machine hours best predict the company's total ut

Crank

Answer:

1)- Variable utilities cost per machine hour = 1.6 per machine hour

2)- Fixed cost = 1740

3)-Total cost on 1220 Machine hour will be

= 3692

Step-by-step explanation:

1) CALCULATE VARIABLE UTILITIES COST PER MACHINE HOUR :

Variable utilities cost per machine hour = Change in cost/high machine hour-low machine hour

=4076-3388/1460-1030

Variable utilities cost per machine hour = 1.6 per machine hour

2) Fixed cost = Total cost-variable cost

= 3388-(1030*1.6)

Fixed cost = 1740

3) Total cost on 1220 Machine hour will be (1220*1.6+1740) = 3692

Write the equation of the circle that has a center of (-7, 17) with a radius of V19.

kipiarov [429]

I think your question seems to be :-

Write the equation of the circle that has a center of (-7, 17) with a radius of √19

So , as we know that the equation of circle with centre at (h,k) and radius r is given by ${\bf{(x-h)^{2}+(y-k)^{2}=r^{2}}}$ . Now , using same concept in this question ;

${:\implies \quad \sf \{x-(-7)\}^{2}+(y-17)^{2}=(\sqrt{19})^{2}}$

${:\implies \quad \bf \therefore \quad \underline{\underline{(x+7)^{2}+(y-17)^{2}=19}}}$

This is the required equation of Circle
