Answer:

Yes

Step-by-step explanation:

(x,y)

Since all the domains (x) are different, this set of number is a function. In a function, the range (y), can repeat.

Find the values of a and b so that the solution of the linear system is (-9,1).
Diano4ka-milaya [45]

Answer:

Step-by-step explanation:

we can write -9 instead of x and y=1 instead of 1

so we write solution again

-9a+1b=-31

-9a-1b=-41

-18a=-72

a=4

we should write 4 instead of a

-9(4)+1b=-31

-36+b=-31

b=5

a=4

Use synthetic division to divide (x3 + 12x2 + 38x + 26) ÷ (x + 4)
KengaRu [80]
Divisor is -4
Use coefficients 1    12    38    26

Bring down 1 multiply by -4 and add to 12 =8
Multiply 8 by -4 and add to 38 = 6 
Multiply 6 by -4 and add to 26 = 2 which is the remainder

looks like     1    12    38    26
                          -4   -32   -24
                    ________________
                     1     8      6     R 2
so answer A of x squared + 8x + 6 +R2 is correct

Which linear function represents the line given by the point-slope equation y – 8 = y minus 8 equals startfraction one-half endf
Marina CMI [18]

The linear function which represents the line given by the point-slope equation is (B) f(x)=\frac{1}{2} x+6.

<h3>What is a linear function?</h3>
  • The word linear function in mathematics refers to two distinct but related concepts.
  • A linear function in calculus and related fields is a function whose graph is a straight line, that is, a polynomial function of degree zero or one.

To find the linear function which represents the line given by the point-slope equation:

Given: y-8=\frac{1}{2} (x-4)

Distribute the right side:

y-8=\frac{1}{2} (x)-\frac{1}{2} 4\\y-8=\frac{1}{2} x-2

Adds 8 on both sides:

y=\frac{1}{2}x-2+8\\y=\frac{1}{2}x+6

Convert to function notation:

f(x)=y\\f(x)=\frac{1}{2} x+6

Therefore, the linear function which represents the line given by the point-slope equation is (B) f(x)=\frac{1}{2} x+6.

The complete question is given below:

Which linear function represents the line given by the point-slope equation y – 8 = y minus 8 equals start fraction one-half end fraction left-parenthesis x minus 4 right-parenthesis. (x – 4)?

A) F(x) = f(x) equals StartFraction one-half EndFraction x plus 4.X + 4

B) f(x) = f(x) equals StartFraction one-half EndFraction x plus 6.

C) X + 6 f(x) = f(x) equals StartFraction one-half EndFraction x minus 10.X –10

D) f(x) = f(x) equals StartFraction one-half EndFraction x minus 12.X – 12
