Answer:
make an account on what ?
Step-by-step explanation:
To determine the value of the given algebraic expression above, we simply substitute the values of each variable to the variables in the expression and evaluate the expression. We do as follows:
6x(y^2)(z)
when x = 0.5
y = -1
z = 2
6(0.5)((-1)^2)(2)
3(1)(2)
6
The value of the algebraic expression would be 6. An algebraic expression consists of variables which are represented with letters like for this case x, y and z, a coefficient which is indicated by numbers (e.g. 6 ) and exponents like 2 for the expression above. Often times expressions contains a number of terms which consists of those elements.
Answer:
9x + 11
Step-by-step explanation:
5(2x+3)-(x+4)
10x+15-x-4 Use distributive property
10x-x +15-4 Combine like terms
9x + 11

Answer:
First, let's write the general transformations:
a) A vertical stretch by a factor of 3.
f(x) ---> 3*f(x)
b) A reflection in the y-axis.
3*f(x) ----> 3*f(-x)
c) A translation of 2 units to the left.
3*f(-x) ----> 3*f(-x + 2)
then we know that:
g(x) = 3*f(-x + 2)
and f(x) = x^2 - x + 1
Then:
g(x) = 3*( (-x + 2)^2 - (-x + 2) + 1)
g(x) = 3*( x^2 - 4*x + 4 +x - 2 + 1) = 3*(x^2 - 3*x + 3)
g(x) = 3*x^2 - 9*x - 9
