Answer:

The algebraic expressions can be presents by words or equivalent expressions, so that its meaning remains same.

Step-by-step explanation:

Different ways to present algebraic expressions without changing their meaning:

1. We can describe the algebraic expressions in words so that its meaning remains same.

For example : 3x+y = Sum of 3 times of an unknown variables x and y.

2. We can describe the algebraic expressions in equivalent expressions, so that its meaning remains same.

For example : 6x+3y = 3(2x+y)

Therefore, the algebraic expressions can be presents by words or equivalent expressions, so that its meaning remains same.

For which value of x does f(x) = g(x)

Natali5045456 [20]

Answer:

x=-3 and x=0

Step-by-step explanation:

The values where f(x) = g(x) is where the graphs intersect

One point is at (-3,0) and the other point is at (0,6)

We have two points of intersection since one is a parabola and the other is a line

Yes or no 2 problems below giving brainlest

astra-53 [7]

Answer:

Problem 13: yes

Problem 14: no

Step-by-step explanation:

Problem 13:

Plug the values of x and y to solve.

-23 = -7(5) + 12

-23 = -35 + 12

-23 = -23

The values are equal, so the coordinates do solve the equation. It's a yes.

-----------------------------------------------------------------------

Problem 14:

Plug the values of x and y to solve.

-9 = -7(-3) + 12

-9 = 21 + 12

-9 = 33

The values are not equal, so the coordinates do not solve the equation. It's a no.

hope this helps :)

Plz help with this question

Vlad [161]

Answer:

We have been given a function and its graph.

$y=4 sin(3t)+2$

The first point should be midline of the given function

We can see the coordinate of the midline which is (-3.14,2) will be the first point.

And second point should be maximum or minimum.

So, there is minimum according to the graph.

The minimum point will be at when $sin3t=-1$

$3t=sin^{-1}(-1)$

$\Rightarrow 3t=-sin^{-1}(1)$

$\Rightarrow 3t=-\frac{\pi}{2}$

$\Rightarrow t=-\frac{\pi}{6}$

$\frac{\pi}{6}=-\frac{1.57}{3}$

So, the minimum point is: $(-\frac{1.57}{3},-2)$
