Answer:

<h2>f(-10) = -75</h2>

Step-by-step explanation:

F(x) is simply another way of saying y. We are given the x value of -10. We can substitute this in for x and find y.

f(-10) = 7(-10) - 5

f(-10) = -70 - 5

f(-10) = -75

Step-by-step explanation:

Given,

2.2x+y=4

x+3y=_3

sol

2x+y=4..... equation i

x+3y=_3 ....eq ii

eq ii of 2 multiple the eq i

2x+y=4

2x+6y=_6

_ _ +

__________

o+ 5y = 10

y =10÷5

y = 2 ans

y valu put the eq 1

2x+y=4

2x+2=4

2x=4_2

2x=2

x=2÷2

x=1

3.

sol

3x+5y=4..... eq 1

x+3y=4 ..... eq 2

eq 2 multiple eq 1. 3

Find the domain and the range of the function <br><br>domain:<br><br>range:<br>​
NeX [460]

Answer:

Approach 1: Mathematical Approach

Domain is the possible inputs or x values of a function

Here we can use any x values greater than or less than 7. We can also use 7 since their is a a function defined for x greater than or equal to 7.

So the domain is (-♾, ♾).

The range is possible y values. Since we can use negative x values, if we plug in x values for the function -5/7x+1, we are going to get positive numbers, as we plug in higher negative numbers, our range is bigger.

This means the range is bounded to -4 so our range is

(-4,♾)

Approach 2: Graphical Approach

Above is the graph

It can take any x values so the domain is (-♾, ♾).

The range is (-4,♾).
