Yes, because 1/4 plus 1/4 equals 2/4 (or 1/2) and 3/4-2/4 equals 1/4.
Answer:
10
Step-by-step explanation:
he can buy 10 because 7×10=70
Answer:
c. 10
Step-by-step explanation:
Pick any two points from the table. I chose (0, -20) and (1, -10)
Let's find the slope between your two points.
(0,−20) (1,−10)
(x1, y1)=(0, −20)
(x2, y2)=(1, −10)
Use the slope formula:
m= y2 − y1 / x2 − x1
= −10 − −20 / 1 − 0
= 10 / 1
= 10
Answer:
The equation of the line would be y = -2x + 8
Step-by-step explanation:
In order to find this, we first need to find the slope of the original equation. We can do this by solving for y.
x - 2y = -6
-2y = -x - 6
y = 1/2x + 3
Now that we have a slope of 1/2, we know the new perpendicular line will have a slope of -2. We know this because perpendicular lines have opposite and reciprocal slopes. This means we flip it and change the sign. Now we can use this slope along with the point to find the equation.
y - y1 = m(x - x1)
y - 2 = -2(x - 3)
y - 2 = -2x + 6
y = -2x + 8
5^(x+3)=25^(x-2)
Apply the exponent rule ( 5 ^2 = 25, so remove the 5 and replace 25?with 2)
x + 3 = 2(x-2)
Simplify:
X + 3 = 2x -4
Add 4 to both sides:
X + 7 = 2x
Subtract x from both sides
X = 7
Answer: x = 7
