Answer:7 + 11x

Step-by-step explanation: you add your letter and number that were in the brackets the since 7 has no number the equation would end and become 7+11x

A worker on the production line is paid a base salary of $230.00 per week plus $0.78 for each unit produced. Write an equation

iogann1982 [59]

(a)

We are given

A worker on the production line is paid a base salary of $230.00 per week

so, base salary =230

Let's assume number pencils produced as x

plus $0.78 for each unit produced

now, we can find equation for earnings

$E(x)=230+0.78x$

now, we are given

her earnings of $446.84 for a week when she produced x units

so, we can set E(x)=446.84

and then we can solve for x

$446.84=230+0.78x$

$230\cdot \:100+0.78x\cdot \:100=446.84\cdot \:100$

$23000+78x=44684$

$23000+78x-23000=44684-23000$

$78x=21684$

$\frac{78x}{78}=\frac{21684}{78}$

$x=278$

so, number of pencils = 278........Answer

(b)

If the worker had produced twice that number of units

so, number of pencils =2*278=556

now, we can find earnings

$E(x)=230+0.78x$

now, we can plug x=556

$E(556)=230+0.78*556$

$E(556)=663.68$ .................Answer

Stels [109]

Answer:

13. c,

14. a.

Step-by-step explanation:

13. The length of a side PQ with coordinates of

P as (x,y) and Q as (w,z)

is: $\sqrt{(x-w)^{2} +(y-z)^{2} }$

so, the length of the side AB =

$\sqrt{(5-5)^{2}+(-2+7)^{2} } =\sqrt{0^{2}+5^{2} } =5$

the length of side BC =

$\sqrt{(5-1)^{2}+(-7+2)^{2} } =\sqrt{(4)^{2}+(-5)^{2} } =\sqrt{4^{2}+5^{2} }$

the length of side AC=

$\sqrt{(5-1)^{2} +(-2+2)^{2} } =\sqrt{4^{2} } =4$

now, the easiest one will be when the vertices are on the coordinate axes.

so, option c will be the most appropriate one.

14. If u see the figure clearly, the lines l and FH are parallel.

the parallel postulate, i.e, the alternate interior angles will always be congruent.

here, the alternate interior angles are angle1 and angle4.

therefore to prove this step, he used parallel postulate as a reason.

so, the correct option is "a"
