Find the slope of each line (each block is one unit):
Answer:
1. 7
2. -3
4. -4/6
Step-by-step explanation:
i solved using y2-y1/x2-x1
Answer:
1. slope= 7
2. slope= -3
3. slope= -2/3
Step-by-step explanation
you find slope by doing rise over run (how much you have to go up/down and left/right to get to the next point.
for the first one, to get from the bottom point to the top point, you have to rise 7, and go to the right 1, which makes 7/1, simplified to 1.
for the second one, you go to rise 6, and then go to the left 2, which makes 6/-2, it is negative because when you have to go left, it just means a negative slope. this simplifies to -3
for the third one, you rise 4 and go to the left 6 from the bottom point to the top point. this makes 4/-6, simplifies to -2/3/
hope this help, i'm not the best explainer though, sorry :(

Kalinda is 68.7 inches tall and wants to know how many inches taller she is than Terrence. If t represents Terrence's height in inches, which expression can she use to find the answer? 68.7 minus t StartFraction t Over 68.7 EndFraction StartFraction 68.7 Over t EndFraction t minus 68.7
Answer:
68.7 - t
Step-by-step explanation:
Here, we are interested in giving the expression that Kalinda can use to know the difference in height between her and Terrence
From the question, Kalinda is 68.7 inches tall while Terrence is t inches tall
To know the difference in their heights, we simply subtract Terrence’s height from Kalinda’a
Mathematically, that would be 68.7 - t

On Jerry's text message phone plan, she paid $0.30 for every 20 messages she sent. what is the cost per message? ___ dollars
which graph best approximates Jerry's text message plan? (on the y-axis each mark is $1
The cost of each message is $0.015.
Option C graph best approximates Jerry's text message plan.
Given,
On Jerry's text message phone plan, she paid $0.30 for every 20 messages she sent.
We need to find what is the cost per message in dollars.
How do we find the unit cost of an item?We divide the total cost by the number of items.
Example: 10 pieces cost $20
1 pieces cost = $20/10 = $2
We have,
$0.30 for every 20 messages.
The cost of each message:
= $0.30/20
= $0.300
= $0.015
We can see that in the graph x-axis represents the number of messages and the y-axis represents the cost of each message.
We have,
$0.30 = 20 messages
3 x $0.30 = 3 x 20 messages
$0.90 = 60 messages.
We need a graph that has a point that intersects $0.90 and 60 messages.
We see that in the graph of Option C.
Option C graph best approximates Jerry's text message plan.
Thus,
The cost of each message is $0.015.
Option C graph best approximates Jerry's text message plan.

A deposit of $10,000 is made into an account that earns 6% interest. Use
your simple interest formula, I=Prt, to calculate the balance after 15 years
Answer:
$19,000
Step-by-step explanation:
The balance is the sum of the principal amount and the interest it earns:
A = P + I
A = P + Prt
A = P(1 +rt)
A = $10,000(1 +.06×15)
A = $19,000 . . . balance after 15 years

Find m_ABD and mZCBD given m ABC = 77º. A (3x + 22) D 16 (5x - 17) B C mZ ABD |° and mZCBD
Answer:
∠ ABD = 49°, ∠ CBD = 28°
Step-by-step explanation:
∠ ABD + ∠ CBD = ∠ ABC , substitute values
3x + 22 + 5x - 17 = 77 , that is
8x + 5 = 77 ( subtract 5 from both sides )
8x = 72 ( divide both sides by 8 )
x = 9
Thus
∠ ABD = 3x + 22 = 3(9) + 22 = 27 + 22 = 49°
∠ CBD = 5x - 17 = 5(9) - 17 = 45 - 17 = 28°

The triangles are similar. Find the missing length x.
Answer:
36
Step-by-step explanation:
If the triangles have similar sides, any increase or decrease in side length is in equal number. This means equal ratio. How?
Let the common factor of decrease in side OD to AP be, z
[tex]\frac{30}{20} = z[/tex]
And, the common factor of decrease in side DT to PN be, z
[tex]\frac{x}{24} = z[/tex]
So, [tex]z = z[/tex]
[tex]\frac{30}{20} = \frac{x}{24}[/tex]
[tex]\frac{30}{20}[/tex] × [tex]24[/tex] = [tex]{x}[/tex]
Therefore,
[tex]{x}[/tex] = [tex]\frac{3}{2}[/tex] × [tex]24[/tex]
= [tex]3[/tex] × [tex]12[/tex]
= [tex]36[/tex]

The Family Arts Center charges $22 for adults, $13 for senior citizens, and $5 for children for their live performance on Sunday afternoon. This past Sunday, there paid revenue was $8526 for 670 tickets sold. There were 49 more children than adults. How many children attended. A 205 B 247 C 208 D 257
Answer:
257
Step-by-step explanation:
Let the number of Adults = x
Number of senior citizens = y
Number of children = z
x + y + z = 670 tickets
The Family Arts Center charges $22 for adults, $13 for senior citizens, and $5 for children for their live performance on Sunday afternoon.
$22 × x + $13 × y + $5 × z = $8526
22x + 13y + 5z = 8526
There were 49 more children than adults.
z = x + 49
x + y + z = 670 tickets
x + y + x + 49 = 670
2x + 49 + y = 670
y = 670 - 2x - 49
We substitute
22x + 13y + 5z = 8526
22x + 13(670 - 2x - 49) + 5(x + 49) = 8526
22x + 8710 - 26x - 637 + 5x +245 = 8526
22x + 5x - 26x + 8710 - 637 + 245 = 8526
x + 8318 = 8526
x = 8526 - 8318
x = 208
The number of Adults = 208
The number rod children is calculated as:
z = x + 49
z = 208 + 49
z = 257
The number of children = 257
A new amusement park ride that last one minute can have up to 1,200 Riders per hour. How many riders can ride per minute.
Pls help
Answer:
20
Step-by-step explanation:
1 hour = 60 minutes
1200 riders = 60 minutes: divide by sixty to set equal to 1
20 riders = 1 minute
Just divide 1,200 by 60 because there are 60 minutes in 1 hour.
Just think about it this way: If you eat 1 banana a minute, you eat 60 bananas an hour. The amusement park ride goes around once a minute. In one hour it goes around 60 times. Each time it carries the same amount of people.
1,200 divided by 60 is...
20!
The ride can carry 20 riders each ride, and each ride lasts a minute.
