The coordinate is an ordered pair (x,y). We have a number, 5, for y, which we can substitute (plug-in) for y in the equation of the line and solve for x.

4x-7y=1\\4x-7(5)=1\\4x=36\\x=9

Nat2105 [25]

Answer:

  • a> h
  • a<164

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

<em>Andre notices that he is a little taller than Lin, who described her height as h > and 150 h < 160 but andre is also shorter than their math teacher who is 164 centimeters tall. select the two inequalities that describe andress height</em>

Please have a look at the attached photo.  

My answer:

Math teacher's height: 164 cm

Let Andre height is :a

We have Heather height: h

<=>  h > and 150 h < 160

<=> 150 < h < 160  

=> two inequalities that describe Andres height

  • a> h
  • a<164

Hope it will find you well

A student loan needs to be paid off beginning the first year after graduation. Beginning at Year 1, there is $52,000 remaining t
Rom4ik [11]

Answer:

The equation is: f(x) = 52000 - 8000x

Step-by-step explanation:

Given

Initial = 52000

Rate = 8000 each year

Required

Determine the equation of the graph

The equation can be determined using.

Amount = Initial - Rate* Years

We used minus (-) because, the amount reduces as the student pays.

Let

y = Amount

x = Years

So, we have:

y = Initial - Rate * x

Substitute values for Initial and Rate

y = 52000 - 8000 * x

y = 52000 - 8000x

Express as a function:

f(x) = 52000 - 8000x

Goal: Find a reasonable domain and range for each function.
slamgirl [31]
D(x) = 32x......ur range will be ur d(x) values and the domain will be ur x values.....where d(x) = total distance and x = gallons.
So we already know that ur car's fuel tank holds 17 gallons....therefore, ur domain has to be 17 gallons or less...but it cant be negative.
so ur domain is : 0 < = x < = 17

now for ur range....since the car only holds 17 gallons....d(x) = 32(17) = 544 miles....thats the farthest it can go...therefore it can go from 0 to 544 miles....so ur range is : 0 < = d(x) < = 544

or u could write it as : domain = (0,17) with 0 representing an empty tank and 17 representing a full tank.....and ur range = (0,544) with 0 representing 0 miles driven and 544 representing 544 miles driven
