X + (2x + 7) = 121 : Write the expression.
3x + 7 = 121 : Combine like terms.
3x + 7 - 7 = 121 - 7 : Isolate x.
3x = 114 : Combined like terms.
3x / 3 = 114 / 3 : Find the value of x.
x = 38 : This is the smaller integer.
(2x + 7) = (2(38) + 7) = 76 + 7 = 83. : Find the value of the larger number by plugging in the value of x to the larger number's quantity.
The larger number is 83, and the smaller number is 38.
Y=x-1
y=6x+4
im not sure about the second one
Answer:
5 is the answer.
Step-by-step explanation:
y= 4x-1
taking derivative with respect to x ,we get
Using distance formula
we have points
at x =-3 the value of y = 4(-3)-1= -12-1 = -13
at x =2 the value of y = 4(2)-1 =7
points are ( -3,-13) and (2,7)
distance formula =
=

Answer:
$2.10
Step-by-step explanation:
The annual dividend will be increased at a constant rate of 1.65% annually.
Therefore:
Let $1.84 be this years payment
For next year, payment = $1.84+(1.65% of $1.84) = 101.65% of $1.84
When we have sequences in which the next term is gotten by multiplication by a constant factor or percentage, it is a Geometric Sequence.
nth term of a Geometric Sequence,
First term, a=1.84
Common ration=101.65%=1.0165
n=8+1=9
The dividend 8 years from now will be $2.10.
C (Y)
It's the only negative slope that goes to -3
