An integer is a whole number and the product of numbers means to multiply them. So so we know that:
x * y = x - 50
So the product (x * y) is 50 less than one of the integers ( x - 50)
I can divide both sides by x:
y = (x - 50) / x where x is not zero
y = x/x - 50/x
y = 1 - 50/ x
x can no longer be zero since you cannot divide by zero
the only way for y to be a whole number is if 50/x is a whole number. 50/x can onky be a whole number if x is a factor of 50. so take any factor of 50 and that will be possible answers.
factors of 50: 1,2,5,10,25,50
these would be possible x values. To to find corresponding y values plug in x
y = 1 - 50/1
y = 1 - 50
y = -49
So first pair is (1, -49)
do the same for the rest and get
(2, -24)
(5, -9)
(10, -4)
(25, -1)
(50, 0)
-2z - xy = z + 7
You are solving for x. Note the equal sign. What you do to one side, you do to the other. Isolate the x.
First, add 2z to both sides
-2z (+2z) - xy = z + 7 (+2z)
Simplify. Combine like terms
-xy = z + 2z + 7
-xy = 3z + 7
Completely isolate the x. Divide -y from both sides
(-xy)/-y = (3z + 7)/-y
x = (3z + 7)/-y
Simplify
z = (3z + 7)/(-y) is your answer
hope this helps
Answer:
16 (1+2)
Step-by-step explanation:
factors of 16: 1,2,4,8,16
factors of 32: 1,2,4,8,16,32
16 x 1 = 16
16 x 2 = 32
120 ft... a flat vertical line is 180 degrees, and since this is a 30,60,90 triangle, your equation is... 180-60=distance John is to the base
First make an equation for first tree
Y=2x+50
Then second tree
Y=1x+59
Then put them equal to eachother
2x+50=1x+59
Solve by subtracting 1x and then subtracting 50
