Y = 4x+1
3x + 2y = 13

we get, x = 1 and y = 5

Step-by-step explanation:

from first equation we get,

y = 4x +1

then,

putting the value of y in second equation :-

=》3x + 2y = 13

=》3x + 2 (4x + 1) = 13

=》3x + 8x + 2 = 13

=》11x = 13 - 2

=》11x = 11

=》 x = 11 / 11

=》 x = 1

putting the value of x in equation 1

=》y = 4x + 1

=》y = (4 × 1) + 1

=》y = 4 + 1

=》y = 5

x=1   y=5

Step-by-step explanation:

plug y = 4x+1 into the second equation, so

3x+2(4x+1)=13 and solve

3x+8x+2=13

11x+2=13

11x+2-2=13-2

11x=11

x=1

then plug x=1 into the first equation

y=4(1)+1

y=4+1

y=5

d. 9

step-by-step explanation:

in the table given in the picture, x is the input of the function and f(x) is the output on the given input. in the given table, it can be read as the value of function at -3 is it's respective value of f(x) which is -9.

as we have to find the value of f(3), we will see that what is the value of output on input 3. we can see in the table that the output value at x=3 is 9.

so, option d is the correct answer ..
