Answer:
1
Step-by-step explanation:
since the 2 functions equal each other:
-2x + 3 = 4x - 9
add -2x to both sides
3 = 6x - 9
add 9 to both sides
12 = 6x
divide by 6
2 = x
you have x, now find y, you just need to plug 2 into one of the equations instead of both bc they both equal the same anyway
-2(2) + 3
-4 + 3
-1 = y
Now we'll find x + y, input them and it's 2 + (-1), which is 1
The 4 members of a robotics team held a car wash to raise money. To attract customers, each person held a sign by the road for an equal portion of the car wash, which lasted 3 hours in all.
Answer:
3/4 or 45 minutes each
Step-by-step explanation:
3 hours are equivalent to 180 minutes which you can then divide by 4. 180/4=45. 45/60 when simplified completely equals 3/4 of an hour
Which diagram represents the following sets?
P=|xis an integer divisible by 2}: Q= (x|xis an odd integer; R =x|xis an integer divisible by 3}
Answer:
The answer is below
Step-by-step explanation:
An integer is a whole number which is either positive, negative or zero.
Given that:
P=(x | x is an integer divisible by 2}. An integer divisible by 2 can be represented by 2k, where k is an integer, hence:
P = (..., -6, -4, -2, 0, 2, 4, 6, ...)
Q= (x | x is an odd integer). An odd integer can be represented by 2k + 1, where k is an integer, hence:
Q = (..., -5, -3, -1, 1, 3, 5, 7, 9 ...)
R = (x | x is an integer divisible by 3). An integer divisible by 3 can be represented by 3k, where k is an integer, hence:
R = (..., -12, -9, -6, -3, 0, 3, 6, 9, ...)
From the above we can see that Q and P are disjoint set, that is P ∩ Q = 0
But P and R have common numbers (..., -6, 0, 6, 12,...) i.e. P ∩ R ≠ 0
Also Q and R have common numbers (..., -3, 3, 9,...) i.e. Q ∩ R ≠ 0

Solve for x 2.3x-3.2+1.6x=.7x
Answer:
x=1
Step-by-step explanation:
Answer:
x = 1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2.3x −3.2 + 1.6x = 0.7x
2.3x + − 3.2 + 1.6x = 0.7x
(2.3x + 1.6x) + (−3.2 )= 0.7x (Combine Like Terms)
3.9x + −3.2 = 0.7x
3.9x − 3.2 = 0.7x
Step 2: Subtract 0.7x from both sides.
3.9x − 3.2 − 0.7x = 0.7x − 0.7x
3.2x − 3.2 = 0
Step 3: Add 3.2 to both sides.
3.2x − 3.2 + 3.2 = 0 + 3.2
3.2x = 3.2
Step 4: Divide both sides by 3.2.
x = 1

with regard to a regression-based forecast, the standard error of the estimate gives a measure of part 2 a. the time required to derive the forecast equation. b. the time period for which the forecast is valid. c. the variability around the regression line. d. the maximum error of the forecast.
The standard error of the estimate gives a measure of the variability around the regression line.
A regression line represents the relationship between an independent and a dependent variable in a statistical study. In this the standard error of the estimate represents the variation from the theoretical value which is on the regression line. So it gives the measure of the variability around the regression line. It is measured from the distance between the values on the regression line and the value of the estimate.
When the standard error is zero, the study is said to be perfect( which is rare in real cases). So a range of error of (0.8-0.9) is considered as acceptable. So to make the estimate precise, standard error should be the minimum.

if neptunes distance from the sun is about 4.5 billion and venus distance is 2x10 to the power of 8 km how many times farther is neptune from the sun than venus?
using scientific notation
If Neptune's distance from the sun is about 4.5 billion km and Venus distance is 2×[tex]10^{8}[/tex] km, then its 22.5 times farther is Neptune from the sun than Venus.
The Neptune's distance from sun = 4.5 billion km
we know
1 billion = [tex]10^{9}[/tex]
The Venus's distance from sun = 2×[tex]10^{8}[/tex] km
How many times farther is Neptune from the sun than Venus = The Neptune's distance from sun / The Venus's distance from sun
Substitute the values in the equation
= (4.5×[tex]10^{9}[/tex])÷(2×[tex]10^{8}[/tex])
= 22.5
Hence, If Neptune's distance from the sun is about 4.5 billion km and Venus distance is 2×[tex]10^{8}[/tex] km, then its 22.5 times farther is Neptune from the sun than Venus.

Susan and bonnie are shopping for school clothes. Susan has $50 and a coupon for a $10 discount at a clothing store where each shirt cost $12. Susan thinks that she can buy three shirts, but bonnie says Susan can by five shirts. The equations used to model the problem are listed below .Solve each equation algebraically ,justify your steps, and determine who is correct.
Answer:
Bonnie is correct
Step-by-step explanation: from the above question:
Susan and bonnie are shopping for school clothes.
Susan has $50 and a coupon for a $10 discount at a clothing store where each shirt cost $12.
Susan thinks that she can buy three shirts, but bonnie says Susan can by five shirts.
Hence:
Discount = $10, Discounted price always carries the minus(-) sign
The cost of 1 shirt = $12
Let the number of shirts she can buy = x
Hence our Equation =
$12 × x - $10 = $50
12x = $50 + 10
12x = $60
x = $60/12
x = 5 shirts
Therefore, Bonnie is correct because she can only buy 5 shirts

Answer:
3
Step-by-step explanation:
We would be eliminating -9x from the equations.
Thus, we need to make the (-3x) into (-9x) in the first equation.
-9x ÷ -3x = 3
After that, you should be able to solve the equations:
-3x - 2y = 2
Equation 1×3: -9x - 6y = 6
-9x + 3y = 24

Use the table. Write an equation for number of subscribers Jayden has during any given month. Use m to represent the number of months and j to represent number of subscribers. I don't know if this will help but he's also trying to get to 1000 subs. along with his friend Keiko.
I said it was J=8m+48 but that's probably very wrong..
Answer:
j = 8m + 48 is correct
Step-by-step explanation:
You see that the y-intercept where x is equal to is 48, and after one month it increases by 8, so we have j = 8m + 48. You were correct
