Answer:
cant not see the photo honey
Step-by-step explanation:
Answer:
For point (1, -2): -2 = -1 - 1 = -2. Therefore, point (1, -2) lies on the graph of the equation.
The graph of the equation is the set of points that are solutions to the equation.
A coordinate pair on the graph of the equation is a solution to the equation.
For the point (0, -1): -1 = -(0) - 1 = 0 - 1 = -1.
Therefore, The point ( 0, −1 ) lies on the graph of the equation.
Step-by-step explanation:

Rearrange the area formula to solve for |
A=lw
Answer: L=A/W
Or you can plug in the values for Area and width.
Step-by-step explanation:
If you divide the total area by the width, you get the length
A: 400
L: ?
W: 50
400=50L
400/50=50L/50
8=L
L=400/50
L=8

what is the solution to this problem? 2x+3(x-10)=45
Answer:
x= 15
Step-by-step explanation:
2x+3(x-10)=45
2x+3x-30=45
Combine like terms:
2x+3x-30 turns into 5x-30= 45
5x-30=45
+30 +30
5x = 75
x = 15
Answer:
x = 15
Step-by-step explanation:
2x+3(x-10)=45
2x+3x-30 =45
5x-30 =45
5x =45+30
5x =75
x =75/5
x =15

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.

Tara has two bags of marbles. The first bag contains 6 red marbles, 5 blue marbles, and 4 green marbles. The second bag contains 3 red marbles, 2 blue marbles, and 4 green marbles. Tara will randomly select 1 marble from each bag.
What is the probability that Tara will select a blue marble from each bag?
Answer:
The first bag, 1 in 3 and the second, 2 in 9.
Step-by-step explanation:
If there are 15 total marbles in the first bag, and 5 blue, there is a 5 in 15 chance, or 1 out of 3 chance she could pull a blue out of the first bag. The second bag, has 9 in total and 2 blue, so there is a 2 in 9 chance she could pull out a blue from the second bag. Hope this helps!

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
4. What does the slope of the equation represent in the context of the problem?
a) the commission per subscription
b) the total amount of money the salesperson makes
c) a one time, yearly commission for all the subscriptions
d) the base salary of the sales person
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.

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

Julio pald 1.2 times his normal hourly rate for each hour he works over 30 hours a week Last week he worked 43 hours and earned $574.56
Answer:
482.70
Step-by-step explanation:
First, find out how much he earned per hour last week. 576.56 divided by 43 is 13.41.
Second, multiply his hourly earnings by 1.2, 1.2*13.41=16.09 So he earns 16.09 per hour
Lastly, multiply 16.09 by 30, 16.09*30=482.7 So he earns about $482.70 each week.
