Answer:
Slope is 5.
Step-by-step explanation:
y + 3x = 8x -7
y = 5x - 7
coefficient in front of x is the slope/rate of change once you get the equation slope intercept for y = mx + b. m is the slope.

The number above the root symbol is the amount of time you have to multiply a number by itself. When we write the square root symbol the 2 is invisible, just like the 1 with a lone variable (x=1x).
In this case it is a cube root
In July 2008, a forest fire near the Park Yosemite National burned about 53 miles squares of forest. If a square mile equals 640 acres, about how many acres of forest were burned?
Answers
Answer:
33,920 acres of forest were burned.
Step-by-step explanation:
In this case, since you know that a square mile is equal to 640 acres, you can use a rule of three to find the acres that are equivalent to 53 square miles:
1 square mile → 640 acres
53 square miles → x
x=(53*640)/1
x=33,920 acres
According to this, the answer is that 33,920 acres of forest were burned.

What is the equation of the line that passes through point Q and is parallel to line P?
Answers
Answer:
[tex]y=\frac{3}{2} x+1[/tex]
Step-by-step explanation:
What we need to know:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)Parallel lines always have the same slope (m) and different y-intercepts (b)1) Find the slope of line P
The slope of a line is equal to the [tex]\frac{rise}{run}[/tex], or the number of units the line moves up over the number of units the line moves to the right.
We can see that for line P, for every 2 units it moves to the right, it moves up 3 units.
Therefore, the slope of line P is [tex]\frac{3}{2}[/tex].
Knowing this, the equation of a line parallel to line P would have a slope of [tex]\frac{3}{2}[/tex] as well. Plug this into [tex]y=mx+b[/tex] as m:
[tex]y=\frac{3}{2} x+b[/tex]
2) Plug the given point Q into [tex]y=\frac{3}{2} x+b[/tex] to find the y-intercept (b)
[tex]y=\frac{3}{2} x+b[/tex]
Plug in point Q (2,4)
[tex]4=\frac{3}{2} (2)+b\\4=\frac{6}{2}+b\\4=3+b[/tex]
Subtract 3 from both sides
[tex]4-3=3+b-3\\1=b[/tex]
Therefore, the y-intercept of this line (b) is 1. Plug this back into our original equation:
[tex]y=\frac{3}{2} x+b[/tex]
[tex]y=\frac{3}{2} x+1[/tex]

PLEASE HELP I HAVE TEST!! Find the measure of the arc or angle indicated
Answers
Answer:
Step-by-step explanation:
<JKL = 90 ( being inscribed angle in semi circle )
< JKP = 38 ( Inscribed angles on same arc are equal )
So now
<PKL = <JKL - < JKP
= 90 - 38
= 52
FINALLY
ARC PL = 2 * < PKL (Relation between arc and inscribed angle )
ARC PL = 2 * 52
= 104

A triangle has sides with lengths of 15 inches, 20 inches, and 25 inches. Is it a right triangle?
Answers
37 inches
Hope this helps!
Answer:
Yes.
Step-by-step explanation:
If the side lengths verify in the Pythagorean theorem, then it is a right triangle.
a² + b² = c²
15² + 20² = 25²
225 + 400 = 625
625 = 625
Since these values come out true when using the Pythagorean Theorem, this triangle is a right trinagle.

Mario was shopping for a new camera. He found one with an original price of $125.00 and is marked 45% off. Sale tax for the item is 5.2%. What is the final price of the camera, including tax?
Answers
Answer:
72.33
Step-by-step explanation:
45 percent of 125 is 56.25 so you subtract that from 125 and get 68.75 and then you do 5.2 percent of 68.75 and get 3.575 which rounds to 3.58 and you add that to 68.75 and get 72.33

How was ice able to fall even though the temperature was much warmer than freezing? a) Ja’quan read the thermometer wrong b) He must have observed hail falling from thunder clouds c) It was cold enough to allow solid precipitation to fall d) Children were most likely throwing ice Reasoning (explain your answer using science facts) _________________________________________ _______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

Find the length of a. Round to 3 decimals.
Answers
Answer:
a ≈ 22.184
Step-by-step explanation:
Using the Cosine rule in Δ ABC
a² = b² + c² - 2bc cosA
Here b = 15, c = 12 and A = 110° , then
a² = 15² + 12² - (2 × 15 × 12 × cos110° )
= 225 + 144 - 360 cos110°
= 369 - 360 cos110°
= 492.12725.. ( take the square root of both sides )
a = [tex]\sqrt{x492.12725}[/tex] ≈ 22.184 ( to 3 dec. places )

(2x + 3x) × (3 + 15) = 12x + 36
(5x) × (18) = 12x + 36

78x = 36
x = 36 / 78
x = 18 / 39

The traingle in Question B and A are right traingle because..If you use pythagoras theorem in those two questions,the sum of square of smaller two sides will be equal to the square larger side. Therefore they are rt.triangle. In D the case is opposite. As the sum of square of two smaller sides are comparatively more than larger sidei.e. hypotenuse. So it is not rt. triangle. This is your answer.
