Step-by-step explanation:
3x - 2y = 19 ...1
Replace y = x-7 in ...1
3x - 2(x-7) = 19
3x - 2x + 14 = 19
x = 19 - 14
= 5
Replace x = 5 in y = x - 7
y = 5 - 7
= -2

which is a y intercept of the graphed function
Answer:
-9
Step-by-step explanation: It crosses the y axis. A y intercept is in when the x axis is 0. So the point would be (0,-9).

Graph (1,1), (1,2), (1,3), (1,4)
Answer:
There is not a way that I can show you how to graph it, so I will try and explain it.
Step-by-step explanation:
(1,1)
^ ^ y-axis
x-axis
You are just going right however many, and then up however many it says.
So if it's (1,1) you will go right one space, and then up one space.
Once you have all of your points on the graph, you put a line through them.
Hope this helps! :)

Other than 1, what are the perfect square factors for 792? From least to greatest.
Answer:
4 and 36
Step-by-step explanation:
Perfect squares are 1, 4, 9, 16, 25, 36, 49, 64, 81
Dividing 792 by these perfect squares results the integer (only) quotients
792 (792 divided by 1)
198 (792 divided by 4
22 (792 divided by 36
The perfect square factors of 792 are, in ascending order, 4 and 36.
From least to greatest, the perfect square factors of 792 are 4, 9 and 36.
Perfect squares are those that are acquired when an integer multiplies itself. For instance, 4 is a perfect square that is a result of 2 multiplying itself.
Other perfect factors include:
4 → 9 → 16 → 25 → 36 → 49 → 64 → 81 → 100 → 121 → 144 → 169 → 196 → 225 → 256 → 289 → 324 → 361The factors of 792 are attached to this answer.
The perfect squares that are also factors of 792 are:
4 , 9 and 36In conclusion, 792 has perfect factors of 4, 9 and 36

Which is greater, 12/17 or 5/8?
Answer:
5/8
Step-by-step explanation:
12/17 is 0.70
5/8 is 0.62
However, 12/17 had a lot more numbers than that so
TRUST ME I GOT EXCEPTED INTO HARVARD
Answer:
12/17 is greater
Step-by-step explanation:
12/17 is greater than 5/8 because to determine which fraction is greater you need to have the same denominator. To get the same denominator I multiplied 17 by 8 and 8 by 17. Since what you do the denominator you have to do the same to the numerator, you would multiply 12 by 8 and 5 by 17 which would lead you to get 12/17= 96/136 and 5/8= 85/136. So, 96/136 > 85/136.

Six identical circles fit inside the rectangle as shown below. If the rectangle has a width of 15
units and a height of 10 units, what is the radius of each circle?
Answer:
The radius of each circle is 2.5 units
Step-by-step explanation:
Width of the rectangle = 15 units
Height of the rectangle = 10 units
6 identical circles fit inside the rectangle,
Two circles fit along the height of the rectangle.
Therefore, diameter of both the circles = Height of the rectangle
2d = 10
d = 5
Since, radius of a circle = [tex]\frac{\text{Diameter}}{2}[/tex]
= [tex]\frac{5}{2}[/tex]
= 25. units
Therefore, Option (4) will be the correct option.

Rewrite the equation in the form (x−p)2=q. 0=x2-16x+26
Answer:
(x - 8)² = 38
Step-by-step explanation:
Given
x² - 16x + 26 = 0 ( subtract 26 from both sides )
x² - 16x = - 26
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 8)x + 64 = - 26 + 64
(x - 8)² = 38 ← as required
96% of all air travel departs on time. If you are taking 3 flights in one day, what is the probability that all of them depart on time?
Answer: 0.884736
Step-by-step explanation:
Given: The proportion of all air travel departs on time: p= 0.96
Total flights : n= 3
Let x be the number of flights on time.
As there are two cases either flight on time or not, so it is a binomial case.
Binomial distribution formula: [tex]P(X=x)=\ ^nC_xp^x(1-p)^{n-x}[/tex]
The probability that all of them depart on time = [tex]P(X=3)=\ ^3C_3(0.96)^3(1-0.96)^0=(1)(0.96)^3=0.884736[/tex]
The probability that all of them depart on time = 0.884736
