2.9. What is the equation of a line parallel to 3x + 4 = y and passing through
(4,-2)?
A. 3x + 10 = y
B. 3x – 14 = y
C. -*-=y
D. --*x+10=y
Answers
Hello! (:
3x+4=y
We want to convert it into slope-intercept form:
y=mx+b
Our equation looks like this:
y=3x+4
Now, parallel lines have the same slope. So if one line has a slope of 3, the line parallel to it has a slope of 3 as well.
Now, we have the slope and a point, so we write the equation in point-slope form:
y-y1=m(x-x1)
y-(-2)=3(x-4)
y+2=3x-12
y=3x-12-2
y=3x-14
Hence, that is the required equation, Hope it helps you!

Answers
Answer:
x = 15
Step-by-step explanation:
a straight line has the angle of 180 degrees
so when added together both angles should equal 180
4x - 17 + 137 = 180
then combine like terms
4x + 120 = 180
and then subtract
4x = 60
and then divide
x = 15
and that is your answer

What are the coordinates of the vertex for f(x) = 3x^2 + 6x + 3? (1 point)
Group of answer choices
(−1, 0)
(3, 6)
(0, −1)
(6, 3)
Answers
Answer:
vertex = (- 1, 0 )
Step-by-step explanation:
Given a parabola in standard form
f(x) = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
x = - [tex]\frac{b}{2a}[/tex]
f(x) = 3x² + 6x + 3 ← is in standard form
with a = 3, b = 6 , then
[tex]x_{vertex}[/tex] = - [tex]\frac{6}{6}[/tex] = - 1
Substitute x = - 1 into f(x) for corresponding y- coordinate of vertex
f(- 1) = 3(- 1)² + 6(- 1) + 3 = 3(1) - 6 + 3 = 3 - 6 + 3 = 0
vertex = (- 1, 0 )
Liam invests $3,670 in a savings account at his local bank which gives 1.9% simple annual interest. He also invests $2,040 in an online savings account which gives 5.5% simple annual interest. After five years, which one will have earned more interest, and how much more interest will it have earned, to the nearest dollar?
Answers
Step-by-step explanation:
Given:
Investment P₁ = $3670Investment P₂ = $2040Rate of interest r₁ = 1.9% SIRate of interest r₂ = 5.5% SITime t = 5 yearsFind amount of interest in both investments:
I₁ = P₁r₁t = $3670*(1.9/100)*5 = $348.65I₂ = P₂r₂t = $2040*(5.5/100)*5 = $561.00As we see the online savings account earns more interest and the difference is:

you can try it by hand or use this:
https://www.calculatorsoup.com/calculators/algebra/quadratic-formula-calculator.php
you get x=2 and x=0.25 these are the x intercepts (where Y is zero and where the graph crosses the x axis)
so mark x=2 and x=0.25 with a dot on a number line and you can draw a straight line between them since that is the part of the graph that is below the x axis (because the equation has <0) it is a positive parabola because the "a" value is positive and the presence of a "b" value means part of the graph will be below the x axis
True of False? The blue radius is perpendicular to the green chord
Answers
Answer:
Step-by-step explanation:
true i think
The statement that the blue radius is perpendicular to the green cord is false.
What are radius and chords?The radius of a circle is any line segment connecting the centre of the circle to any point on the circle. The chord of a circle is a line segment joining any two points on the circle.
From the complete question,
The blue radius does not bisect the green chord
This means that the blue radius and the green chord do not meet at 90 degrees
Since both lines do not meet at 90 degrees, then they are not perpendicular
Hence, the statement that the blue radius is perpendicular to the green cord is false

The dimensions of a right triangle are shown in the diagram.
What is the length of the missing side, to the nearest tenth of a centimeter?
Answers
Answer:
18.4 cm
Step-by-step explanation:
For this problem, you would use Pythagorean Theorem or a^2+b^2=c^2. Don't forget that the c in the formula is always your hypotenuse or the longest side of the triangle. The a and the b are always the legs of the triangle. (It doesn't matter which leg is which letter) The hypotenuse is also always across from the 90 degree angle. Picture the 90 degree angle as an arrow pointing to the hypotenuse. In this case, the hypotenuse (or c) is 20.7 cm. Now all you have to do is plug and chug! I hope this helps you and thanks for asking your question!!

a bag contains 300 balls. 96 balls are yellow. Which answer shows both the correct proportion and the correct percent of yellow balls in the bag.
Answers
The proportion of yellow balls in the bag is 8/25 and percentage is 32 %
What is Percentage and Proportion?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
Given data ,
The number of balls in the bag = 300
The number of yellow balls in the bag = 96
The proportion of yellow balls =
The number of yellow balls in the bag / The number of balls in the bag
The proportion of yellow balls = 96 / 300
= 24 / 75
= 8 / 25
Therefore , The proportion of yellow balls in the bag is 8 / 25
Now ,
The percentage of yellow balls in the bag =
Number of yellow balls in the bag / Number of balls in the bag x 100 %
The percentage of yellow balls in the bag = ( 8 / 25 ) x 100 %
= 8 x 4 %
= 32 %
Hence ,
The proportion of yellow balls in the bag is 8/25 and percentage is 32 %

Find the equation of the line, whose slope is 5 and x- intercept is 2
Answers
Answer:
Step-by-step explanation:
when x intercept is points given, then y = 0
So far, you have y = 5x + b where b = the yintercept
x = 2
y = 0
0 = 5x + b
0 =5 * 2 + b
0 = 10 + b Subtract 10 from both sides.
-10 = b
Equation: y = 5x - 10

5x + 8y = 139
x + y = 20
x = 20 - y
5x + 8y = 139
5(20 - y) + 8y = 139
100 - 5y + 8y = 139
100 + 3y = 139
3y = 139 - 100
3y = 39
3y/3 = 39/3
y = 13
x + y = 20
x + 13 = 20
x = 20 - 13
x = 7
