Step-by-step explanation:
Write an equation of the line that passes through (1,2) and is parallel to the line y = -5x+4
Answer:
y =-5x + 7
Step-by-step explanation:
y = -5x + 4
Slope = -5
Parallel lines have same slope
Slope of the parallel line to this line = -5
(1 , 2)
y -y1 =m(x - x1)
y - 2 = -5(x - 1)
y -2 = -5x + 5
y = -5x + 5 + 2
y = -5x + 7

Write the equation for an exponential function that triples ever year, x, when the original amount is 4.
Answer:
y = 4(3)^x
Step-by-step explanation:
Here, we want to write the exponential equation
From the question, we have the equation tripling in x value every year and the original amount is 4
The exponential equation is of the form;
y = a(b)^n
In this case;
a = 4 , b = 3 and n = x
So we have the equation as;
y = 4(3)^x

t = 45
You didn't post the choices, hope that I can help you.
Answer:
Any year after 1985
Step-by-step explanation:
8453=2828+125t
5625=125t
45=t
1940+45=1985

Answer:
BC ≈ 5.44 m
Step-by-step explanation:
Using the cosine ratio in the right triangle
cosθ = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] , that is
cos27° = [tex]\frac{BC}{6.1}[/tex] ( multiply both sides by 6.1 )
6.1 × cos27° = BC , then
BC ≈ 5.44 m ( to 3 significant figures )

a line is perpendicular to y=-2x+5 and intersects the point (-4,2). what is the equation of this perpendicular line?
Answer:
y = 1/2x + 4
Step-by-step explanation:
If the line is perpendicular to y = -2x + 5 then the new line has a slope of 1/2.
So solve for b: using y = mx + b
2 = 1/2(-4) + b
2 = -2 + b
4 = b
Put it all together
y = 1/2x + 4

What is the missing reason for the 3rd step in the proof below?
A. If two lines are parallel, then alternate interior angles are congruent
B. Corresponding angles theorem
C. Vertical angles are congruent
D. If two lines are parallel, then alternate exterior angles are congruent
Answer:
The missing reason for the 3rd step in the proof below is;
C. Vertical angles are congruent
Step-by-step explanation:
In the two column proof, we have;
Statement [tex]{}[/tex] Reason
1. AB ║ CD [tex]{}[/tex] 1. Given
2. ∠3 ≅ ∠7 [tex]{}[/tex] 2. Corresponding angles theorem
3. ∠7 ≅ ∠6 [tex]{}[/tex] 3. Vertical angles are congruent
4. m∠3 = m∠7 [tex]{}[/tex] 4. Definition of congruence
m∠7 = m∠6
5. m∠3 = m∠6 [tex]{}[/tex] 5. Substitution
6. m∠3 ≅ m∠6 [tex]{}[/tex] 6. Definition of congruence
Vertical angles are the angles formed on the opposite sides of two straight lines when they cross each other
