Answer:
Step-by-step explanation:
since 105 + z is a straight line we know it equals 180 so we can use this equation
180 = 105 + z
simplify
75 = z
the since we know that all quadrilaterals equal 360 degrees we can add our two given number and z then subtract from 360:
102 + 85 + 75
= 262
now subtract
360 - 262
= 98
y = 98

X equals negative fifteen
Answer:
18
Step-by-step explanation:
18.07 is 0.07 away from 18 and 0.93 away from 19 therefore 18.07 is closest to 18
The general equation of a straight line is in the form of;
Y=MX + c,
Where m is the gradient and
C the y-intersept.
Parallel line have the same gradient.
From the equation,
Y=-1/4X - 2,
Gradient = - 1/4.
Now assuming that the second line passes through (x,y) and (-3,2).
(Y-2)/(X--3) =-1/4
4(Y-2)=-1(X+3)
4Y-8 = -X-3
4Y = -X -3+8
4Y = -X +5
Y = -1/4X +5/4
Answer:
The following equations is, 
Step-by-step explanation:
Let two integers be x and y.
As per the given statement:
The product of two integers is 112.
⇒ 
......[1]
Also, One number is 4 more than three times the other.
⇒ y = 3x +4 ......[2]
Now substitute equation [1] in [2] we get
Using distributive property i.e, 
Simplify:
therefore, the equation could be used to find one of the numbers is;
