-x - y = 1 . . . . . (1)
y = x + 3 . . . . . (2)
Putting (2) into (1), gives:
-x - x - 3 = 1
-2x = 1 + 3 = 4
x = 4/-2 = -2
From (2), y = -2 + 3 = 1
Therefore the two line will intersect at the point (-2, 1)
4x+y=5 or b is the correct answer:) Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.
Answer:
The answer to your question is 8 h
Step-by-step explanation:
Data
length of the ladder = 200 cm
distance between each rung = 20 cm
rate = 10 cm/h
fifth rung = ?
Process
1.- Calculate the total distance the tide must rise
distance = 20 cm x 4
= 80 cm because the first rung touches the water
2.- Calculate the time
rate = distance / time
-Solve for time
time = distance / rate
-Substitution
time = 80 cm / 10cm/h
-result
time = 8 h
Answer:
no
Step-by-step explanation:
Similar triangles have angles with the same measures.
angles in the first triangle are 50°, 60°, 70°.
angles in the second triangle are 50°, 50°, 80°.
The angles do not have the same values, so the triangles cannot be similar.
_____
<em>Comment on the question</em>
When 2 of the three angles are different, the third angle cannot make the triangles similar. We don't even need to compute the third angle to answer this question.
