Answer:

y = x + 15

Step-by-step explanation:

okay so you're gonna use the y2-y1/x2-x1 formula to find the slope (m)

24 - 19/9 - 4 = 5/5 = 1

so that is your slope (m)

and now if you follow your slope then you should get your y-intercept (b)

4 - 1 = 3 19 - 1 = 18

(3, 18)

3 - 1 = 2 18 - 1 = 17

(2, 17)

2 - 1 = 1 17 - 1 = 16

(1, 16)

1 - 1 = 0 16 - 1 = 15

(0, 15)

so thats your y-intercept (b)

and the equation will look like:

y = mx + b y = x + 15 or y = 1x + 15 (but the 1 isn't necessary)

Corrected Question

Given a triangle with two sides 4.1 cm and 6.7cm and an Included angle of $35^\circ$ . Use the Law of Cosines to determine the length of the third side of the triangle.

Answer:

(D) 4.1cm

Step-by-step explanation:

Given a triangle with two sides 4.1 cm and 6.7 cm and an included angle of $35^\circ$ .

Using Law of Cosines

$a^2=b^2+c^2-2bc\cos A\\a^2=4.1^2+6.7^2-2*4.1*6.7\cos 35^\circ\\a^2=16.6958\\a=\sqrt{16.6958}\\a=4.09\\a \approx 4.1$ cm$

The correct option is D.

What type of error is present in the underlined

Aleksandr [31]

Answer:

Type of error: Run-on(comma splice).

Best revision to fix it: Adding a semicolon after beginners .

Explanation:

A run-on sentence is described as a sentence in which two independent clauses are joined inappropriately. It could be either comma splice where the two independent clauses are incorrectly linked using a comma or fused sentence when the two clauses run-on without employing appropriate coordinating conjunction or punctuation marks to separate the two ideas.

In the given sentence, it exemplifies a comma splice type of run-on sentence error. To fix this error, a semicolon after 'beginners' can be employed instead of a comma. This will help in connecting the two ideas appropriately where the first idea leads the second. Thus, the final sentence reads as:

'The guitar is another excellent instrument for beginners; however, it takes more practice than a recorder.'
