Answer:
B) (-∞,∞)
Step-by-step explanation:
The domain is the x-values, so it’s all real numbers in this graph.
I would use interval notation and choose B) (-∞,∞)
The range is the y-values, so it’s (2,-1), if that’s the next question.
Answer:
x = 78º
y = 35º
Step-by-step explanation:
These are isosceles triangles
two angles are congruent
-----------------------------
x + 51 + 51 = 180
x = 180 - 102
x = 78º
y + y + 110 = 180
2y = 70
y = 35º
Answer:
a=13 - 4b/5
b=65/4-5a/4
Step-by-step explanation:
The formula of an area of a triangle:
b - base
h - height
We have b = 8x and h = 7x. Substitute:
<h3>Answer: 28x²</h3>
Answer:
⅓x + y = 5⅓
or
⅓x + y = 5.3333333
or
⅓x + y = 16/3
Step-by-step explanation:
Solve for slope using rise/run
Y2 - Y1 / X2 - X1
(6) - (5) / (-2) - (1)
1 / -3
Slope: -⅓
y = -⅓x + b
solve for b using one of the points
I'll be using (1,5)
Substitute the point into the equation
5 = -⅓(1) + b
5 = -⅓ + b (add ⅓ to both sides)
+⅓ +⅓
5⅓ = b
5⅓ can also be written as 16/3 or 5.333333
The equation is now:
y = -⅓x + 5⅓
Convert to standard form by adding ⅓x to both sides
y = -⅓x + 5⅓
+⅓x +⅓x
Solution: ⅓x + y = 5⅓
