Answer:
3
Step-by-step explanation:
Since the triangles are congruent.
The hypotenuses are equal.
13 = 4x + 1
13 - 1 = 4x + 1 - 1
12 = 4x
12/4 = 4x/4
3 = x
Answer:
c
Step-by-step explanation:
Answer:
It's the first option.
Step-by-step explanation:
y = cos x transformed to cos (x - π/2) moves the graph π/2 units to the right.
Multiplying by 3 to give 3 cos(x - π/2) stretches the graph 3 units parallel to the y-axis and adding 3 to this moves the graph up 3 units.
So the required equation is y = 3(cos x - π/2) + 3.
Answer:
Option 3 3 1/8x - 6 3/10
Step-by-step explanation:
(3 1/2x - 4 1/10) - (3/8x + 2 1/5)
Divide it into parts:
(3 1/2x - 3/8x) + (-4 1/10 - 2 1/5)
3 1/2x - 3/8x = 3 4/8x - 3/8x = 3 1/8x
-4 1/10 - 2 1/5 = -4 1/10 - 2 2/10 = -6 3/10
So we get:
2 1/4x - 6 3/10
Well 3x is 3 times if they are together beside each other that mean they are multiplying so 3 times x plus 5times y = -5
