Answer:
- x + 3 = y ....... slope = -1 and y-intercept of 3
x - 3 = y ......... slope = 1 and y-intercept of -3
y = 3 x - 1 ......... slope = 3 and y-intercept of -1
y = 1 - 3 x ....... slope = -3 and y-intercept of 1
Step-by-step explanation:
Just read the slope and y intercept from the equations since they are all given in slope-intercept form:
- x + 3 = y ....... slope = -1 and y-intercept of 3
x - 3 = y ......... slope = 1 and y-intercept of -3
y = 3 x - 1 ......... slope = 3 and y-intercept of -1
y = 1 - 3 x ....... slope = -3 and y-intercept of 1
70000000 the reason that this is the answer to this is because if multiply 10 by 7 you will have 70 and just add 6 zeros
Answer: Option D.
Step-by-step explanation:
To solve this exercise you must keep on mind the Angle at the Center Theorem.
According to the Angle at the Center Theorem, an inscribed angle is half of the central angle.
Therefore, given in the inscribed angle m∠BAC=35°, you can calculate the central angle m∠EFD as following:
- Solve for EFD.
- When you substitute values. you obtain:
Let ab be a 2 digit number, then ab=10a+b, where a and b are digits, a≠0.
"the difference between the integer and the product of its two digits is 12"
10a+b - (a*b)=12
10a+b-ab=12
factorize b:
10a+b(1-a)=12
subtract 10 from both sides, to produce a factor (1-a) or (a-1) and then factorize:
10a-10+b(1-a)=2
10(a-1)+b(1-a)=2
(a-1)(10-b)=2
(a-1)(10-b) can be (1,2), (2, 1), (-1, -2), (-2, -1)
if a-1=1 and 10-b=2, then a=2, b=8
if a-1=2, and 10-b=1, then a=3, b=9
if a-1=-1, then a=0, which is not possible
if a-1=-2, then a=-1, which is not possible
so the solutions (a, b) are (2, 8) and (3, 9)
Then the integers are 28, 39
Answer: 28, 39
