This doesn’t make any sense, because 8n-8n<=-9-2
Which means 0<=-11 which doesn’t make sense, therefore this there are no solutions for this inequality.

Which of the following uses estimation to check 267 - 154 = 113
mamaluj [8]
Answer: it is the third but there is a typo. It is C. 267 - 150 = 117

Explanation:

You can do that estimation searching to make a quick verification, because adding rounding 154 to the tens leads to 150 and it is very easy to subtract 267 - 150 instead of 267 - 154, driving to a quick approximate check of the subtraction.

Help please I would appreciate it !

Answer/Step-by-step explanation:

Given:

Line equation => 2.1x + 9.9y - 9.2 = 0

Required:

x-intercept and y-intercept of the line.

SOLUTION:

The x-intercept is the point where the line intercepts the x-axis. To find the x-intercept of the line for which the equation is given above, set y = 0 and solve for x.

2.1x + 9.9(0) - 9.2 = 0

2.1x + 0 - 9.2 = 0

2.1x - 9.2 = 0

2.1x - 9.2 + 9.2 = 0 + 9.2

2.1x = 9.2

\frac{2.1x}{2.1} = \frac{9.2}{2.1}

x = 4.4 (approximated)

The y-intercept is the point where the line intercepts the y-axis. At this point, x = 0. Set x = 0 and solve for y to find the y intercept.

2.1(0) + 9.9y - 9.2 = 0

9.9y - 9.2 = 0

9.9y - 9.2 + 9.2 = 0 + 9.2

9.9y = 9.2

y = \frac{9.2}{9.9}

y = 0.9 (approximated)

ralph is an electrician . he cgarges an initial fee of $16 plus $33 per hour if ralph earned $197 on a job how long did the job
KiRa [710]

x=#of hours worked
33 per hour or 33x (since 33 times every hour)
initial fee is independed of hours so
fee=33x+16

if fee=197 then solve for hours or x
197=33x+16
subtract 16 from both sides
181=33x
divide both sides by 33
5.4848484848=x
he worked 5.48 hours
