Mathematics
1 answer:
solniwko [45]3 years ago
8 0

Answer:

∠1 = 40

Step-by-step explanation:

So due to the alternate interior angles theorem, angle 1 and angle 2 equal each other so:

2x + 20 = 3x + 10

subtract 2x from both sides

20 = x + 10

subtract 10 from both sides

10 = x

Now input 10 into the equation

2(10) + 20

20 + 20

40

Given the term 3x², select ALL of the like terms listed below. Question 3 options: A.-2x²
atroni [7]

Answer:

A.-2x^2

D.5x^2

E.x^2

Step-by-step explanation:

Like terms must have the same variable, in this case x, and the same exponent, in this case 2. Since the original term is 3x^2, the like terms will be those that contain x^2, regardless of whether their coefficient or sign is different.

Analyzing the options:

A.-2x^2

We have the same variable and the same exponent x^2, so it is a like term.

B. 3x

You have the same variable x but not the same exponent. So it's not a like term of 3x^2

C.3x^3

Same variable x but as in the previous case, the exponent is different, it is a 3 and it should be a 2, so it is not a similar or like term.

D.5x^2

In this option we do have the x^2, so it is a like term of  3x^2

E.x^2

It is also a like term because it contains the x^2.

In summary the like terms are:

A.-2x^2

D.5x^2

E.x^2

If f(x) = startfraction 7 over x endfraction, then what is the slope of f(x) at x = 5? round your answer to 3 decimal places.
Flura [38]

The slope of the function to 3 dp is 0.280

<h3>Slope of a function</h3>

Slope is also known as the gradient of a function

Given the function f(x) =\frac{7}{x}

Taking the derivative of the function will give:

f'(x)=-\frac{7}{x^2}

Substitute x = 5 into the equation to have:

f'(x)=-\frac{7}{5^2}

f'(x) = -\frac{7}{25}

Hence the slope of the function to 3 dp is 0.280

Cheyanne plans to put $150 into a savings account. She can place her money into an account represented by f(x) = 5x + 150, or in
ycow [4]
(5×3)+150=165
150×(1.03)^(3)=163.91

(5×10)+150=200
150×(1.03)^(10)=201.59

f(x) has the highest value in 3 years; g(x) has the highest value in 10 years
