Is the number xx? I would take it as x.

Product for four and x. = 4x

Six less than product = 4x - 6

10 POINTS IDENTIFY THE SLOPE, Y-INTERCEPT AND GRAPH. 1. Y = 2x + 3 2. Y = 3/4x - 2

Alenkasestr [34]

Answer for problem 1: slope = 2, y intercept = 3

Answer for problem 2: slope = 3/4, y intercept = -2

Explanation:

Both equations are in the form y = mx+b. This is known as slope intercept form. This is because we can read off the values of the slope and y intercept very quickly. We have y = 2x+3 match up with y = mx+b. The m is the slope and b is the y intercept. So m = 2 and b = 3 for this equation. A similar situation happens with the other equation as well. It might help to rewrite the second equation into y = (3/4)x + (-2).

12. Use a trigonometric ratio to find the measure of O in the triangle below. Give your answer to the nearest degree.

Given :-

A right angled triangle with two sides 10cm and 9cm .

To Find :-

The value of theta .

Solution :-

At angle theta , 9cm side will be considered as the perpendicular and 10cm side will be hypotenuse . So , as we know that ;

$\longrightarrow sin\theta =\dfrac{perpendicular}{hypotenuse}$

Substituting the respective values,

$\longrightarrow sin\theta =\dfrac{9cm}{10cm}$

Simplify,

$\longrightarrow sin\theta= 0.9$

Take arcsin both sides ,

$\longrightarrow \theta =sin^{-1}(0.9)$

$\\\longrightarrow\underline{\underline{\theta = 64.15^o }}$

Hence the required answer is 64.15° .

last question. thanks for wasting your time answering my questions that I could probably answer my self if I wasn't such a lazy

Alina [70]

Lol I'm glad to answer your questions :D

So in the last question, it uses the word "per" which basically means you would have to multiply the number of pounds times 1.69

So it would be $1.69a

HELP PLEASE I DONT KNOW WHAT TO DO

Softa [21]

The first blank should be -5. The second should be -10. The third one should 10, if it’s talking about the opposite of -10.
