(z+7)^2=3
z^2+14z+46=0
z={-14+-√(14^2-4.1.46)}/2.1
=-14+-√(196-184)/2
=-14+-√12/2
=-14+-2√3/2
=-7+-√3
so it is,
z=-7+√3
or,
z=-7-√3
first we shall learn the rules.when numbers with same sign are divided it gives pisitive sign but, when numbers of different signs are divided it gives negetive sign.
here,
7. (-154) ➗ (-14) =11
11. (-40) ➗10=-4
15. 90 ➗ (-15)=-6
16. 108 ➗ (-9)=-12
17. (-48) ➗ (-6)=8
18. (-105) ➗ 7=-15
hope it helps you......
Step-by-step explanation:
Given that f(x)=x²-3x+6 and g(x)=x+6. Solve the equations (a) f(x)=2g(x) (b) f(x)=g(2x)
Answer:
dividing by 100
Step-by-step explanation:
Answer:
slope: ; y-intercept: 1
Step-by-step explanation:
First, you must rearrange the function into y = mx + b form:
2x + x = 4(y - 1)
Simplify both sides:
3x = 4y - 4
Subtract 3x and 4y from both sides:
-4y = -3x - 4
Divide both sides by -4:
y = + 1
Now that it is in y = mx + b form, you can find the slope and y-intercept. In y = mx + b form, m is the slope and b is the y-intercept. Therefore:
m = = slope
b = 1 = y-intercept
