X = 12
because if you notice, each of the angles have a little arc in the corner, which means they are congruent. if all three angles are congruent, that means each angle is 60° because each triangle has a maximum value of 180°. therefore, this means it is an equilateral triangle.
that being said, each side must be equal as well. so, you can use any two sides to find x by using each one on a different side of an equation, then isolating and solving.
5x - 22 = 3x + 2 = 4x - 10
so
5x - 22 = 3x + 2
3x + 2 = 4x - 10
4x - 10 = 5x - 22
whichever one you solve for, x = 12. and if you plug in that number for x, each side equals the same number = 38
X = time, minutes
y = length, inches
When x = 32 min, y = 11.2 in
When x = 32+18 = 50, y = 10.75 in
Assume that a linear relatioship exists between x and y.
In table form, the given data is
x, min: 32 50
y, in: 11.2 10.75
The slope is
m = (10.75 - 11.2)/(50 - 32) = -0.025
In point-slope form, the required equation is
When x = 3 hours = 180 minutes, obtain
y - 10.75 = -0.025*(180 - 50) = -3.25
y = -3.25 + 10.75 = 7.5 in
Answer: 7.5 inches
Answer:
x ∈ {-2, 1, 4}
Step-by-step explanation:
The graph shows y = 0 when x = -2 or 1 or 4. Hence these values of x are the zeros of the function.
