write the linear equation from the given information in slope intercept form (-1,3); slope=-3
Answer:
y = -3xStep-by-step explanation:
The standard expression of equation of a line in slope-intercept form is expressed as;
y = mx+c
m is the slope
c is the intercept
Given
slope m = -3
Point (x, y) = (-1, 3)
x = -1 and y = 3
Get the intercept
To get the intercept c, we will substitute the given values into the equation above to have;
y = mx+c
3 = -3(-1)+c
3 = 3 + c
c = 3-3
c = 0
Substitute m = -3 and c = 0 into the equation above;
y = mx+c
y = -3x+0
y = -3x
Hence the required linear equation is y = -3x

Pls I need help with this geometry problem. It's due today.
Step-by-step explanation:
Yz / RT = SZ / ST
2X +2 / 3X -7 = 35 / 40= 7 / 8
8( 2x+2) = 7( 3x-7 )
16 x +16 = 21x 49
5x = 65
x =13
YZ = 2×13 +2 = 28

Express as a product: 1-2cos(2a)
I've been really struggling with this. Please help & explain it.
Answer:
(2sin a - 1)(2sin a + 1)
Step-by-step explanation:
Here, we want to express what is given as a product
Mathematically;
cos2a = 1-2sin^2A
So we have;
1-2(1-2sin^a)
= 1 - 2 + 4sin^2a
= 4sin^2a - 1
Using the difference of two squares, this is;
(2sin(a) - 1)(2sin a + 1)

Note: Enter your answer and show all the steps that you use to solve this problem in the space provided. a) Simplify the expression and explain each step. (2 points) 4 ( 3 x + 2 ) − 2 b) Factor the expression completely. (1 point) 20 b − 16
Answer:
Step-by-step explanation:
To simplify the expression:
4(3x+2) - 2
The first step is to open the brackets
= 4 * 3x + 4* 2 - 2
= 12x + 8 - 2
= 12x - 6
Factor out the above expression, we get;
= 6(2x - 1)
To factor out the expression:
20b - 16
the factor that can be divided by 20 and 16 without remainder is 4;
So, we have:
= 4(5b - 4)
Evaluate this

Answer:
D. [tex]\frac{1}{27}[/tex]
Step-by-step explanation:
[tex]3^{-3}[/tex] = [tex]\frac{1}{27}[/tex]. First you need to remove the negative exponent, to do this move the term into the denominator. [tex]\frac{3^{-3} }{1}[/tex] becomes [tex]\frac{1}{3^{3} }[/tex], then solve for [tex]3^{3}[/tex], which equals 27. So your answer is [tex]\frac{1}{27}[/tex].

Eighteen 2.5 gallon buckets are needed to fill a cistern with water. Find the constant of variation. Please help! Thank you!
Given:
Eighteen 2.5 gallon buckets are needed to fill a cistern with water.
To find:
The constant of variation.
Solution:
If y is directly proportional to x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
Where, k is constant of variation.
In the given problem, water in cistern (w) is directly proportional to number of buckets (n).
[tex]w\propto n[/tex]
[tex]w=2.5n[/tex] (Capacity of each bucket is 2.5 gallons)
Therefore, the constant of variation is 2.5.

On a town map, each unit of the coordinate plane represents 1 mile. Three branches of a bank are located at A(−3, 1), B(2, 3), and C(4, −1). A bank employee drives from Branch A to Branch B and then drives halfway to Branch C before getting stuck in traffic. What is the minimum total distance the employee may have driven before getting stuck in traffic? Round to the nearest tenth of a mile if necessary.
The minimum total distance the employee may have driven before getting stuck in traffic is
miles.
Answer:
7.6 miles
Step-by-step explanation:
Given the coordinate points :
A(−3, 1), B(2, 3), and C(4, −1)
Distance (d) between A and B:
x1 = - 3 ; x2 = 2 ; y1 = 1 ; y2 = 3
d = √(x2 - x1)² + (y2 - y1)²
d = √(2 - (-3))² + (3 - 1)²
d = √25 + 4
d = 5.385 miles
BC :
d = √(x2 - x1)² + (y2 - y1)²
d = √(4 - 2)² + (-1 - 3)²
d = √2² + (-4²)
d = √4 + 16
d2 = 4.4721359 miles
(1/2) of d2 = 1/2 * 4.4721359 = 2.236 miles
Total distance = (5.385 + 2.236) miles
Total distance driven before getting stuck in traffic = 7.6 miles
The exterior angle of a regular polygon is 60°.
What is the name of the regular polygon?
Step-by-step explanation:
exterior angle = 60°
exterior angle = 360/n
60° = 360°/n
60n = 360°
n = 6
A regular polygon with 6 sides is a HEXAGON.
