Answer:
x = 45
x = 19
Step-by-step explanation:
A straight line = 180°
So,
12.
3x + x = 180
4x = 180
---- -----
4 4
x = 45
13.
(5x + 4) + (x - 2) + (3x + 7) = 180
Combine like terms:
(5x + 4) + (x - 2) + (3x + 7) = 180
9x + 4 - 2 + 7 = 180
9x + 9 = 180
-9 -9
------------------
9x = 171
----- -----
9 9
x = 19
Hope this helped.
We know that
slope m=(y2-y1)/(x2-x1)
then
case a) x=18
m=(y2-y1)/(18-18)--------------> is undefined, because <span>the denominator is zero
case b) </span><span>2y-6x=0
2y=6x------------> y=3x
the slope m=3-----------> m is defined
case c) y=9
</span>m=(9-9)/(x2-x1)--------> m=0-----------> m is defined
case d) y=x
m=1---------------> m is defined
the answer is
x=18 has an undefined slope
Answer:
The two numbers are 10 and 6.
Step-by-step explanation:
Let's begin by calling these two numbers x and y, and setting up a system of equations.
x-y=4
x*y=60
Now, you can rearrange the first equation to find the value of x expressed through y.
x=y+4
Now, you can substitute this into the second equation.
(y+4)*y=60
y^2+4y=60
y^2+4y-60=0
(y-6)(y+10)=0
y=6
x=6+4=10
Hope this helps!
Answer:
27
Step-by-step explanation:
4 times 4 is 16
2 boxes in the middle
4 tiny boxes in each one in the middle
1 entire one on the outside
1+4+4+2+16= 27
