Answer:

Step-by-step explanation:

F(x) = 2x+3 is just a function, so if you replace one of the "x" with 4 you have to replace the other one so it just becomes

F(4) = 2(4) + 3 then you do 2(4) = 8 then add 3 to it and it gets you 11.

Answer:

40.00

Step-by-step explanation:

una sandia 10.00

un banano 2.00

un aguacate 3.00 (porque una docena equivale 12 artículos; 36/12 es 3)

una sandía 10.00

una docena de bananos 12(2.00) = 24.00

dos aguacates 2(3.00) = 6.00

10.00 +24.00 +6.00

=40.00

7/a = 28/40 how to do this

Korvikt [17]

So first we cross multiply

7/a times 7/40 which equals = 28a and 280

Divided both sides by 28.
28a divided by 28 = A. Then 280 divided = 10

So a = 10

Let g(x, y) = cos(x + 5y). (a) Evaluate g(10, −2). g(10, −2) = (b) Find the domain of g. −1 ≤ x ≤ 1, − 1 5 ≤ y ≤ 1 5 −5 ≤ x ≤ 5,

RoseWind [281]

Answer:

since $Cos(z)$ is a function defined for all $z\in \mathbb{R}$ , then there is not restriction for $x+5y$ , thus, the domain of $g(x,y)$ is $\mathbb{R}^2$ and in interval notation is $(-\infty,\infty)\times(-\infty,\infty)$

Since $Cos(x+5y)\in\mathbb{R}$ then the range of $g(x,y)$ is the interval [-1,1].
