Answer:
9x or 15x
Step-by-step explanation:
-3x + 12x = 9x
-3 + 12 = 9,
or if you just straight out add

The temperature at 5:30 a.M. Was –4° Fahrenheit (F). Eight hours later, at 2:30 p.M., the temperature is the opposite of –4 °F. What is the temperature at 2:30?
Answer: 4°F
Step-by-step explanation:
From the question, we are informed that temperature at 5:30 a.m was –4°F and that eight hours later, at 2:30 p.m, the temperature is the opposite of –4°F.
The temperature at 2:30 will be 4°F since the opposite of -4 is +4. Also since there's an interval of 8 hours, it's likely that the temperature increased by 1° for every hour. In 8 hours, it'll have increased by 8°, therefore the temperature will then be:
= -4 + 8
= 4°F

An average person can type 2,4002,400 words per hour. Trista types at the same rate as the average person and made the double number line below to estimate how long it will take her to type her research paper. Using Trista's double number line, estimate how long it will take her to type her 1,400-word research paper.
Answer:
35 minutes
Step-by-step explanation:
Given that:
Trista:
Average word type per hour = 2400 words /hr
For Trista to type her 1400 word research paper ;
It will take 'h' hour
If
2400 words = 1 hour
1400 words = h
Cross multiply :
2400h = 1400
h = 1400 / 2400
h = 0.5833333 hr
To minutes, it will take :
0.5833333 * 60 = 35 minutes
Hence, it will take Trista 35 minutes or 0.5833333 to type her 1400 words research paper.

rafael took 4 pumpkin pies to a family gatherig if he divides each pie into six equal-sized sliced how many slices can he serve
If -6x+12=0 and 4y + 5=9, what is the value of ×+y
Answer:
x=2 y=1 x+y= 2+1=3 3 is the value of x+y
Step-by-step explanation:
Answer:
X=2, Y=1
X+Y=3
Step-by-step explanation:
-6x+12=0. first subtract 12 from each side
-6x=-12 now divide both sides by -6
X=2
4y+5=9. subtract 5 from each side
4y=4 divide both sides by 4
Y=1
2+1=3

Rewrite the following equation in slope-intercept form.
17x - 20y = -14
Answer:
17/20x + 7/10 = y
Step-by-step explanation:
You can solve this equation by moving values until they fit the form y=mx+b (slope-intercept form).
17x - 20y = -1417x + 14 = 20y17/20x + 14/20 = y17/20x + 7/10 = yHope this helps!!
Answer:
Step-by-step explanation:
Slope intercept form y=mx+b
-20y = -14 -17x
Y = 14/20 + 17/20x
Y = 17/20x + 14/20

Fully factorise
X^3 - 100
Answer:
(x-10)(x²+10x+100)
Step-by-step explanation:
Given the expression
X^3 - 100
This ca also be expressed as;
X^3 - 100 = X³ - 10³
a³-b³ = (a-b)(a²+b²+ab)
Substitute a = x and b = 10
X³ - 10³ = (x-10)(x²+10²+10x)
X³ - 10³ = (x-10)(x²+10x+100)
Hence the factored form is (x-10)(x²+10x+100)

Which shows the difference (p ^ 2 + 6p + 2)/(4p ^ 2) - (10p ^ 2)/(4p ^ 2) ?
Answer:
-9p²+6p+2/4p²Step-by-step explanation:
Given the expression
(p ^ 2 + 6p + 2)/(4p ^ 2) - (10p ^ 2)/(4p ^ 2)
Find the LCM
The LCM = 4p²
[p²+6p+2 - (10p²)]/4p²
Expand
p²-10p²+6p+2/4p²
-9p²+6p+2/4p²
hence the required expression is -9p²+6p+2/4p²
y=-x-4

What is The difference between 3 7/10 and 2 2/5
Answer:
1 3/10
Step-by-step explanation:
3 7/10 - 2 2/5 =
3 7/10 - 2 4/10 =
1 3/10
Answer:
1 3/10
Step-by-step explanation:
Change the denominator of 2 2/5 to 10 to match denominators by multiplying 2 (numerator and denominator)
New equation: 3 7/10 - 2 4/10 = 1 3/10
Solve the following proportion for x.
X/13 = 17/7
Round your answer to the nearest tenth.

7x = 221
x = 221 / 7
x = ~31.6
Sketch the image of A (-3,5) after the described glide reflection.
Translation: (x, y)=(x - 2, y + 5)
Reflection: in y =4
Plz HELP me out I really don’t understand this!
Answer:
Translation (x, y) = (x - 2, y + 5)
(x, y) = (x - 2, y + 5)
(-3, 5) = (-3 - 2, 5 + 5)
(-3, 5) = (-5, 10)
So this means that point A' (-5, 10) is your translation of point A (-3, 5) .
Now let us look at the reflection. It says to reflect across the y = 4. Basically you will draw a horizontal straight line on 4. Count how many units is point A (-3, 5) is. Then do it on the other side of the line. Point A' (-3, 3) is reflected across y = 4 of point A (-3, 5).
Hope this helps, thank you !!
Consider sample data with x = 12 and s = 3. (a) Compute the coefficient of variation. % (b) Compute a 75% Chebyshev interval around the sample mean. Lower Limit Upper Limit
Answer: a) 25%
b) 75% Chebyshev interval around the sample mean=(6,18)
Step-by-step explanation:
Given: Sample mean: [tex]\overline{x}=12[/tex]
Sample standard deviation: s= 3
a) Coefficient of variation = [tex]\dfrac{s}{\overline{x}}\times100[/tex]
[tex]\\\\=\dfrac{3}{12}\times100\%=\dfrac{100\%}{4}\\\\=25\%[/tex]
b) According to the Chebychev's theorem,
75% of the population lies within 2 standard deviations from the sample mean.
i.e. 75% Chebyshev interval around the sample mean. = [tex](\overline{x}-2s,\ \overline{x}+2s)[/tex]
[tex]=(12-2(3),\ 12+2(3))\\\\=(6, 18)[/tex]
Hence, the 75% Chebyshev interval around the sample mean=(6,18)
