We need to combine like terms, so 4x-3x, and 8y+2y. x+10y is it simplified

Answer:

x + 10y

Step-by-step explanation:

To simplify this question, we need to collect like terms. For terms to be considered like terms, they have to have identical variables with identical exponents. Coefficients may be different. So 4x and 3x are like terms. 8y and 2y are also like terms.

4x + 8y - 3x + 2y = x + 10y

Let f(x)=14/7+2e^−0.6x . What is f(3) ? Enter your answer, rounded to the nearest tenth, in the box.

Gelneren [198K]

Answer:

$f(3)=1.9$

Step-by-step explanation:

we have

$f(x)=\frac{14}{7+2e^{-0.6x}}$

we know that

f(3) is the value of the function for the value of x equal to 3

substitute the value of x=3 in the function

$f(3)=\frac{14}{7+2e^{-0.6(3)}}=1.9$

Please help me with this math question

natta225 [31]

ANSWER

$x = 54\degree$

EXPLANATION

The diameter meets the tangent to the circle at right angles.

The sum of interior angles of a triangle is 180°.

This implies that

$x + 36 \degree + 90 \degree = 180 \degree$

Group the constant terms

$x = 180 \degree - 36 \degree - 90 \degree$

We simplify to obtain,

$x = 54\degree$

Drag the point A to the location indicated in each scenario to complete each statement.

Art [367]

The graph from which the position of the point A can determined following

the multiplication with a scalar is attached.

Responses:

If A is in quadrant I and is multiplied by a negative scalar, c, then c·A is in quadrant III

If A is in quadrant II and is multiplied by a positive scalar, c, then c·A is in quadrant II

If A is in quadrant II and is multiplied by a negative scalar, c, then c·A is in quadrant IV

If A is in quadrant III and is multiplied by a negative scalar, c, then c·A is in quadrant I

<h3>Methods by which the above responses are obtained</h3>

Background information;

The question relates to the coordinate system with the abscissa represent the real number and the ordinate representing the imaginary number.

Solution:

If A is in quadrant I; A = a + b·i

When multiplied by a negative scalar, c, we get;

c·A = c·a + c·b·i

Therefore;

c·a is negative

c·b is negative

c·A = c·a + c·b·i is in the quadrant III (third quadrant)

If A is quadrant II, we have;

A = -a + b·i

When multiplied by a positive scalar c, we have;

c·A = c·(-a) + c·b·i = -c·a + c·b·i

-c·a is negative

c·b·i is positive

Therefore;

c·A = -c·a + c·b·i is in quadrant II

Multiplying A by negative scalar if A is in quadrant II, we have;

c·A = -c·a + c·b·i

-c·a is positive

c·b·i is negative

Therefore;

c·A = -c·a + c·b·i is in quadrant IV

If A is in quadrant III, we have;

A = a + b·i

a is negative

b is negative

Multiplying A with a negative scalar c gives;

c·A = c·a + c·b·i

c·a is positive

c·b is positive

Therefore;

c·A = c·a + c·b·i is in quadrant I
