Write an expression that has two terms. Your expression should have a variable and a constant.

Answers

Answer 1

Answer: Quite simply: 2+x

A constant is simply a number, something that does not change: here it's "2"

A variable can chage: here it's "x" - anything can be substituted for x

If we put those two together with a "+" sign, we get an expression: variables or contants (including multipled ones: such as 2x, which is a term) added to each other or subtracted from each other

Una máquina llena 4 baldes de helado en 30 minutos, funcionando siempre a la misma velocidad Si ante un corte de luz, solo funcionó durante 45 minutos, ¿cuántos baldes habrá llenado?

Answers

Answer:

La máquina llenó:

6 baldes

Step-by-step explanation:

Por regla de tres:

4 baldes son a 30 minutos

M baldes son a 45 minutos

M = 45*4/30

M = 180/30

M = 6

Answers

Answer:

22) (B)

24) (D)

25) (D)

28) (B)

29) (D)

Step-by-step explanation:

22) Firstly, the figure is reflected across line m and then the figure is reflected across line n.

The resultant figure is a rotated figure of original figure

(B) Rotation

24) Since there are 12 people sitting in a circle

Total circular angle = 360°

Angle between two people = 360/12 = 30°

Therefore, from Abbey to Kai there are 2 people between them. Hence, angle covered = 60°

From Kai to Haifa there are 3 people.

Angle covered = 90°

(D) is correct

25) Lacy passes the soup in 90° counterclockwise and then 30°.

Now soup is in front of Haifa.

(D) is correct

Coordinates are ((0,2) -----> (x-1,y-3) = (-1,-1)

(-7,3) -------------> (x-1,y-3) = (-8,0)

(03,-2) --------> (-4,-5)

(B) is correct

Reflection of P(0,0) across x= -3, gives the point( -6,0)

And reflection across y=4, gives the point (0,8)

Together the reflected point is P(-6,8).

(D) is correct

Solve the equation for x -x*2-10x+24=0

Answers

Answer:

x=-12 x =2

Step-by-step explanation:

-x^2-10x+24=0

Divide by -1

x^2 +10x -24 = 0

Factor

What 2 terms multiply to -24 and add to 10

12 * -2 = -24

12 -2 = 10

(x+12) ( x-2) = 0

Using the zero product property

x+12 =0 x-2 =0

x=-12 x =2

The answer is x=-12 an x=2

Answers

If the $f(x)$ and $t(x)$ are even function then $fo\ t\ (x)$ is an even function, if $f(x)$ and $t(x)$ are odd function then the function $fo\ t\ (x)$ is an odd function and if $f(x)$ is even and $t(x)$ is odd then the function $fo\ t\ (x)$ is an even function.
