Find the slope of the line that passes through the points (1.9) and (2, 5).
AV
Answer:
-2 is the slope
Step-by-step explanation:
Slope=Rise/Run=(y2-y1)/(x2-x1)=(5-9)/(2-1)=-4/2=-2, therefore the slope is -2

A mixture of purple paint contains 8 teaspoons of red paint and 12 teaspoons of blue paint. To make the same shade of purple paint using 36 teaspoons of blue paint, how much red paint would you need?
Answer:
24 teaspoons of red paint would be needed.
Step-by-step explanation:
Given that the initial mixture contains 8 teaspoons of red paint and 12 teaspoons of blue paint, this mixture contains a total of 20 units of paint, of which 8 are red, that is, 8 out of 20. Therefore, the proportion of red paint is 40%, while the proportion of blue paint is 60% remaining.
Therefore, in the case of making the same mixture (with the same proportion) using 36 teaspoons of blue paint, the necessary amount of red paint is determined through the following calculation:
60 = 36
40 = X
((40 x 36) / 60) = X
1,440 = 60 = X
24 = X
Thus, 24 teaspoons of red paint would be needed.
percentage of households with internet access is equal to 60%

Hello, I need the steps. I'm kinda confused. Thanks!
Answer:
y = -[tex]\frac{2}{3}[/tex] x - 3
Step-by-step explanation:
The general form of the equation of the line (linear equation) is:
y = ax + b
The line passes through (-3, -1) and (6, -7), i.e:
(1) (x=-3, y=-1) is a point that verifies the equation of the line, and
(2) (x=6, y=-7) also verifies the equation.
So we can put up a system of 2 equations to obtain a and b:
y = ax + b
(1) -1 = a (-3) + b
(2) -7 = a (6) + b
______________
substracting (1) - (2) we can obtain a:
-1 - (-7) = a (-3-6) ⇒ 6 = -9 a ⇒ a = -2/3
by replacing a in (1) we can obtain b:
-1 = -2/3 (-3) + b ⇒ -1 -2 = b ⇒ b = -3
so, the equation is: y = ax + b ⇒ y = -2/3 x - 3
Verification: (2) giving x= 6, let's see if y=-7 is obtained:
y = -2/3 6 - 3 ⇒ y = -4 - 3 = 7 ⇒ RIGHT!
the line segment shown is reflected over the y - axis what are the new coordinates of point A
After living in his house for 15 years, a man sold it for Rs. 7,000 profit and purchased a new
one for Rs. 1,000 more than twice the selling price of his old one. If the new house cost 3 times
the original price of the old one, what did he pay for each?
please answer it asap. thanks in advance:)
Answer:
He paid 5,000 for the old home, which was the original price of it.
And he paid 15,000 for the new home.
Step-by-step explanation
Twice the selling price of his old one, the selling price was 7,000
7,000 * 2 = 14000.
14000 + 1000 = 15000.
15,000 is three times more than he originally paid for his old home.
n Purchased a new one for 1,000 more than twice the selling price.
Based on △GHI below, which of the following inequalities is true?
Answer:
C. [tex] \overline{GI} < \overline{GH} < \overline{HI} [/tex]
Step-by-step explanation:
In a triangle, the longest side is opposite to the largest measure of angle. The medium side is opposite to the medium angle, while the shortest side is opposite to the smallest angle.
In ∆GHI,
✍️m<G = 95°, it is opposite to [tex] \overline{HI} [/tex]
<G is the largest angle, therefore, [tex] \overline{HI} [/tex] is the longest side.
✍️m<I = 180 - (95 + 38) = 47°.
<I is opposite to [tex] \overline{GH} [/tex]
<I is the medium angle, therefore, [tex] \overline{GH} [/tex] is the medium side.
✍️m<H = 38°, it is opposite to [tex] \overline{GI} [/tex]
<h is the smallest angle, therefore, [tex] \overline{GI} [/tex] is the shortest side.
✅This means:
[tex] \overline{GI} < \overline{GH} < \overline{HI} [/tex]
PLEASE HELP ME I NEED THIS DONE SOON AND I DKNT UNDERSTAND IT
Answer:
Step-by-step explanation:
1/2 + b + h
Okay so we know that b is 6 and that h is 10 so we can change the question to this : 1/2 + 6 + 10. We know that 1/2 is also writen as 0.5 , now all you need to do is 0.5 + 6 + 10 = 16.5 . The question asks to round to the nearest 10th so you need to add a 0 after the 5 so you can round up or down.
16.50
Now you need to look at the 10th number which is 5 and to round it up you need to look at the number after that which would be 0, we know that anything that is 4 or below gets rounded down so your answer for this question is simply 16.5.
I hope that helped you and good luck!
What is y = -1/3x - 9
Answer:
Step-by-step explanation:
Use the slope-intercept form
y=mx+b
to find the slope m and y-intercept b.
Slope: −13
y-intercept: (0,−9)
is y = -x + 5 non-linear or linear
Answer:
It's linear
Step-by-step explanation:
Linear equations have no exponents higher than a 1, which is the case for this equation cause if there's no exponent it's cause it's just a 1. Non-linear has a exponent higher than a 1, ex. [tex]x^{2}[/tex]

Is y=10 a function?
Answer:
Yes
Step-by-step explanation:
x=10 would not however since it is a vertical line and fails the vertical line test where an x value cannot be repeated more than once.
y=10 would be a horizontal line coming from the point (0,10)

A roller coaster is going down the slope and the speed is 6m/s . 10 seconds later it has reached the bottom of the slope with a speed of 35m/s. what is the acceleration
Answer:
The acceleration is 2.9m/s^2
Step-by-step explanation:
Given
[tex]Initial\ Speed\ (u) = 6m/s[/tex]
[tex]Final\ Speed\ (v) = 35m/s[/tex]
[tex]Time\ (t) = 10s[/tex]
Required
Determine the acceleration
This question will be answered using Newton's first equation of motion.
[tex]v = u + at[/tex]
Substitute values for v, u and t
[tex]35 = 6 + 10 * a[/tex]
[tex]35 = 6 + 10 a[/tex]
Collect Like Terms
[tex]10a = 35-6[/tex]
[tex]10a = 29[/tex]
Solve for a
[tex]a = 29/10[/tex]
[tex]a = 2.9[/tex]
Hence, the acceleration is 2.9m/s^2
Help!!!!please, I need to answer this question
Answer:
m<B = 62°
Step-by-step explanation:
Given that ∆ABC is congruent to ∆TUV, it follows that their corresponding angles are equal to each other. Therefore:
m<B = m<U
m<B = (3y + 2)°
m<U = (4y - 18)°
Thus,
3y + 2 = 4y - 18
Collect like terms
18 + 2 = 4y - 3y
20 = y
y = 20
m<B = (3y + 2)°
Plug in the value of x
m<B = 3(20) + 2
m<B = 60 + 2
m<B = 62°

Answer:
y = 69
Step-by-step explanation:
start with the distributive property:
5/9 * y and 5/9 * 3
and now you have: 5/9y + 15/9 = 40
and we have to isolate y so subtract 15/9 from both sides:
5/9y + 15/9 = 40
- 15/9 -15/9
and now you have 5/9y = 345/9
and now divide both sides by 5/9 so: 5/9y divided by 5/9 = y
and 345/9 divided by 5/9 = 345/5 and lets simplify....
y= 69
hope this helps luv
