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

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.
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)
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)

Step-by-step explanation:
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 !!

AA'B'C' is a reflection of AABC. Which best describes the reflection?
Answer:
A reflection over the line y = 3.
Step-by-step explanation:
You will draw a straight vertical line on 3 and then count the spaces. If you have equal space on both sides then your answer is right.
Rewrite the system of equations in slope intercept form
Y - 5 = -4x
3y - 9 = -6x
The slope-intercept form of the first equation is _______
The slope intercept form of the second equation is _______
Answer:
✔ y = –4x + 5
✔ y = –2x + 3
Step-by-step explanation:
We can write -
The slope-intercept form of the first equation is y = - 4x + 5.The slope intercept form of the second equation is y = - 2x + 3.What is the general equation of a Straight line?
The general equation of a straight line in slope intercept form -
y = mx + c
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
Other possible equations of lines are -
(y - y₁) = m(x - x₁) {Point - slope form}(y - y₁) = (y₂ - y₁) × (x - x₁)/(x₂ - x₁) {Two point - slope form}x/a + y/b = 1 {intercept form}x cos(β) + y sin(β) = L {Normal form}We have the given system of equations as -
y - 5 = - 4x
3y - 9 = - 6x
The given system of equations is -
y - 5 = - 4x
3y - 9 = - 6x
Now -
y - 5 = - 4x
y = - 4x + 5
and
3y - 9 = - 6x
3y = - 6x + 9
y = (-6/3)x + (9/3)
y = - 2x + 3
So, we can write -
The slope-intercept form of the first equation is y = - 4x + 5.
The slope intercept form of the second equation is y = - 2x + 3.
Therefore, we can write -
The slope-intercept form of the first equation is y = - 4x + 5.The slope intercept form of the second equation is y = - 2x + 3.To solve more questions on straight lines, visit the link below-

help please!! i dont understand geometry
Answer:
116
Step-by-step explanation:
so to find angle bcs we need to find x and to find x we need to create an equation. 160= angle scd +anglebcs so we do 180=3x+17+12x+8 and solve for x
160=3x+17+12x+8
step 1 combine like terms
160=15x+25
step 2 subtract 25 from each side
135=15x
step 3 divide each side by 15
9=x
then we plug in 9 to 12x+8 and get 116

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
