Answer:Domestic Stamps: 123
Foreign Stamps: 89
Step-by-step explanation:
So we have two equations
x - y = 34
x + y =212
Let's take the first equation and put it in terms of x
x-y+y= 34+y
x= 34 + y
Now that we have a value for x, substitute it into the second equation for x and solve for y.
(34+y)+y=212
34+y+y = 212
34+2y= 212
34-34+ 2y=212-34
2y= 178
2y/2=178/2
y= 89
Now that we know the value for y, we can substitute it into the first equation and solve for x.
x-89=34
X-89+89=34+89
X=123
Y= 89
X =123
ANSWER
Domestic Stamps: 123
Foreign Stamps: 89

(17,-7) and (13,-4)]
Answer:
3/4
Step-by-step explanation:
(17,-7) And (13,-4). First take -4 and subtract it from-7. When you do that you get 3. Then Subtract 13-17. You get 4. Write 3 and 4 as a fraction. 3/4. The 3 is the x-value and the 4 is the y value. So 3/4 is your slope
Step 1: –10 + 8x < 6x – 4 Step 2: –10 < –2x – 4 Step 3: –6 < –2x Step 4: ________ What is the final step in solving the inequality –2(5 – 4x) < 6x – 4?
Given:
The inequality is
[tex]-10+8x<6x-4[/tex]
To find:
The missing step in solving the given inequality.
Solution:
Step 1: The given equation.
[tex]-10+8x<6x-4[/tex]
Step 2: Subtract 8x from both sides.
[tex]-10+8x-8x<6x-4-8x[/tex]
[tex]-10<-2x-4[/tex]
Step 3: Add 4 on both sides.
[tex]-10+4<-2x-4+4[/tex]
[tex]-6<-2x[/tex]
Step 4: Divide both sides by -2 and change the sign of inequity as we divide the inequality by a negative number.
[tex]\dfrac{-6}{-2}>\dfrac{-2x}{-2}[/tex]
[tex]3>x[/tex]
Therefore, the missing step is [tex]3>x[/tex].

Which rigid transformation(s) can map TriangleMNP onto TriangleTSR? reflection only rotation only translation, then reflection translation, then rotation
Answer:
C.) translation, then reflection
Step-by-step explanation:
It just is...I already know someone is about to see my answer and come up with this super logical explanation but dude this is just the simple terms of geometry at least in the topic I'm learning.....plus I got it correct on my quiz on edge lol
The triangle MNP is translated and then reflected. Then the correct option is C.
What is a transformation of a shape?A point, line, or mathematical figure can be converted in one of four ways, and each has an effect on the object's structure and/or position. Picture, after translation, refers to the object's ultimate organization and placement. From just before the refers to the material's initial condition.
The translation does not change the shape and size of the geometry. But changes the location.
The reflection does not change the shape and size of the geometry. But flipped the image.
The triangle MNP is translated and then reflected. Then the correct option is C.

Sam has started mowing lawns to save money for a new bike that costs $190. He charges $20 per hour for mowing lawns, and $35 per hour for gardening. However, he has to pay his dad $120 for the use of his lawnmower. Which of the following equations could be used to find the number of hours Sam has to work to buy his bike if m represents the number of hours he mows lawns, and g represents the number of hours he spends gardening? Group of answer choices
Answer:
310 = 20m + 35gStep-by-step explanation:
As per give we have
Earning = 20m + 35gSpending =$120Target amount = $190The equation to consider all is
190 = 20m + 35g - 120 ⇒ 310 = 20m + 35gSo correct option is the second one

-3 is less than -7.
-3 is greater than -7.
The absolute value of -3 is less than the absolute value of -7.
The absolute value of -3 is equal to the absolute value of -7.
.) The absolute value of -3 is greater than the absolute value of -7.
DONE
Answer: -3 is greater than -7 and the absolute value of -3 is less than the absolute value of -7.
Step-by-step explanation:
For NEGATIVE numbers, the closer the value is to 0, the greater it is. -3 is closer to 0 than -7 is, so -3 is greater than -7. For POSITIVE numbers, the further away the number is from 0, the greater it is. The absolute value of -3 is 3 and the absolute value of -7 is 7, and 7 is farther away from 0 than 3 is. So, the absolute value of -3 is less than the absolute value of -7. Hope this helps!
84 divided by 10.92 long division(with work)
Answer:
7.692
Step-by-step explanation:
Divide 84 by 10.92 to get 7.69230769231
Round 7.69230769231 to the nearest thousandth to get 7.692.
Answer: 7.69 rounded
Step-by-step explanation: The numbers go on further but I just rounded it to the hundredths. The full number if you want is 7.69230769231.
Now, Change the divisor 10.92 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.
We then have the equations:
8400 ÷ 1092 = 7.69
and therefore:
84 ÷ 10.92 = 7.69
Both calculated to 2 decimal places.
0 0 0 7. 6 9

Remember that it can keep going on for more decimal places, but this is to 2 decimal places so the answer to 2 decimal places is 7.69.

What is the equation of the line that is horizontal and goes through the y-axis
at -4?
Answer:
y = - 4
Step-by-step explanation:
The equation of a horizontal line parallel to the x- axis is
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (0, - 4) with y- coordinate - 4, thus
y = - 4 ← equation of horizontal line
What is the correct answer?
Answer:
C) y = 10/3x - 5
Step-by-step explanation:
Slope intercept equation is y = mx + b:
m is the slope
b is y-intercept
When you read slope you can also read it as rise over run. Rise is move up or down on the y axis depending if number is negative or positive. Run is move left or right on x axis depending if number is negative or positive.
Example: y = [tex]\frac{10}{3} x - 5[/tex]
Start at the y-intercept which is -5. On graph you can see the line crosses the y axis at (0, -5). From this point rise 10 then run 3 you'll end up at point (3, 5). Connect the dots of the two points and you'll see a line like the one in the problem.

Given: AC and BD bis, each other.
Prove: ABCD is a parallelogram
Answer:
because AC and BD bis => AX = XC; BX = XD
ΔAXD ≅ ΔCXB (SAS) because: AX = CX
DX = BX
m∠AXD = m∠BXC ( 2 opposing angles)
because ΔAXD ≅ ΔCXB (SAS)
=> AD = BC and m∠DAX = m∠BCX
because m∠DAX = m∠BCX => AD//BC
ABCD has AD = BC and AD//BC => ABCD is a parallelogram

A Tech Software salesperson earns a base salary of $40,000 plus a commission of $3000 for every subscription to the software they sale.
2. Write an equation, in slope-intercept form, that shows the total amount of income the salesperson earns if he sells x subscriptions in a year.
3. What does the y-intercept of the equation represent in the context of the problem?
a) the base salary of the salesperson
b) the total salary of the salesperson per year
c) the amount of money the salesperson makes per software sale.
d) none of these

WANT A EXTRA 10 PTS?
comment on this and ill make another problem for 10 pts!
Answer:
y = 3000x + 40000a) the base salary of the salespersona) the commission per subscriptionStep-by-step explanation:
Slope intercept form is found by [ y = mx + b ] where m = slope and b = y-intercept. We are given that a salesperson gets $40000 as a base salary. Since this value doesn't change it is the starting value, in other words the y-intercept. The salesperson also gets $3000 for every subscription they sell. Since this amount grows at a constant rate, that is the slope. Now, we can write the slope intercept form of [ y = 3000x + 40000 ].
Best of Luck!
Answer:
1. y = 3000x + 40000
2. Option A: base salary of the salesperson
3. Option A: the commission per subscription
Step-by-step explanation:
1. The commission of $3000 will be the first number, then will come the salary. Now, since it has to be in slope form, it is on the y-intercept, so we write y.
2. It is the base salary because it is the only number that does not have a missing value, 3000x does.
3. The commission per subscription is the answer because the context of the whole slope is the commission per subscription. Question 2 was the y-intercept.
Find the slope from the points given:
(18, -5), (18, 20)
Answer:
UNDEFINED
Step-by-step explanation:
change in y over the change in x is how you'd find slope, however, x is the same in both of these, making this a limitation not an equation, therefore the slope is undefined 18-18 = 0 -> Anything divided by zero as a slope is undefined.
