Write an equation of the line with the given slope and y-intercept 1.slope=7;y-intercept=2 2.slope 1/3;y-intercept =-1
Answer:
1. y = 7x + 2
2. y = 1/3x - 1 or 3y = x - 3
Step-by-step explanation:
Use this formula y = mx + b where the slope is represent by "m" and the y-intercept is represent by "b"
1. y = mx + b
y = 7x + 2
2. y = mx + b
y = 1/3 x + (-1) Let clean this up by multiplying each term by 3
3y = 1x - 3 or 3y = x - 3

Answer:
50km
Step-by-step explanation:
Explanation:
So the map has a scale of 1 cm: 20 km. Next, you look at how far they are apart and see if the scale and the distance on the map are the same measurement. In this case, they are both centimeters so they stay the same. Then, all you do is multiple the real size, 20 km, by 2.51. Then, 20 x 2.5=50. So the answer is 50 km

Form a polynomial whose real zeros and degree are given.
Zeros: -1, 0, 4;
degree: 3
Answer:
f(x)=x(x-3) x (x+4) x (x-9
Step-by-step explanation:
your function in factored form
The polynomial whose real zeros and degree are given is f(x) = x³ - 3x² - 4x
How to form the polynomial?The given parameters are:
Zeros: -1, 0 and 4Degree = 3Rewrite the zeros as:
x = -1, x = 0 and x = 4
Set the zeros to 0
x + 1 = 0, x = 0 and x - 4 = 0
Multiply the zeros
(x + 1) * x * (x - 4) = 0 * 0 * 0
Multiply the factors
(x² + x) * (x - 4) = 0
Multiply the factors
x³ - 4x² + x² - 4x = 0
Evaluate the like terms
x³ - 3x² - 4x = 0
Express as a polynomial function
f(x) = x³ - 3x² - 4x
Hence, the polynomial whose real zeros and degree are given is f(x) = x³ - 3x² - 4x

2. Find the perimeter of a rectangle of
Length 13m with an area of 65m
Answer:
Perimeter = 36m
Step-by-step explanation:
Area = l x w
65m = 13m x w
5m = w
Perimeter = 2(l + w)
Perimeter = 2(13m + 5m)
Perimeter = 36m
Answer:
36m
Step-by-step explanation:
The equation for the area of a rectangle is A = w*l, where w = width and l = length
Since we already have the area and the width, we can plug those values into the equation to find the width (w)
A = w*l
65 = w*13
we can divide both sides by 13 to isolate the w variable, and we get that
w = 5
The equation for the perimeter of a rectangle is
P = 2(l +w)
P = 2(13 +5)
P =36
The perimeter is 36m

Find the missing side of each triangle. Round your answers to the nearest tenth if necessary. (Please Show your work)
Answer:
x = + 14.88 km
Step-by-step explanation:
Let's solve for x using the Pythagorean Theorem.
The length of the hypotenuse is 15.8 km; that of the shorter leg is 5.3 km.
Since a² + b² = c², we get:
(5.3 km)² + x² = (15.8 km)²
Solving for x², we obtain (15.8 km)² - (5.3 km)² = 249.64 km² - 28.09 km²
The last expression returns the value 221.55 km² for x²
Taking the square root of both sides, we get x = + 14.88 km
___________

[tex]\boxed{ \rm{answer \: by \: { \boxed{ \rm{☆HayabusaBrainly}}}}}[/tex]
Step by step :x² = (15,8)² - (5,3)²
x² = 249,64 - 28,09
x² = 221,55
x = 14,88km✔
divide inverse function 2x³+1
Answer: The Inverse Function goes the other way: So the inverse of: 2x+3 is: (y-3)/2. The inverse is usually shown by putting a little "-1" after the function name, like this: f -1(y) We say "f inverse of y". So, the inverse of f(x) = 2x+3 is written: f -1(y) = (y-3)/2.

Step-by-step explanation:
Slope intercept form: y = mx + b
y -6 = 4(x + 3)
y - 6 = 4x + 12
Add 6 to both side
y = 4x + 12 + 6
y = 4x + 18

Answer:
The Answer is 16
Step-by-step explanation:
The three angles enclosed in a triangle, made by its sides, are called its internal angles. The sum of internal angles of a triangle is
180
o
. Based on its internal angles, a triangle can be classified as acute angled, right angled and obtuse angled.
Your Welcome! :)
The sum of the measure of angle of a triangle = 180° .
Given two angles = 92° and 72°
_________________________
92° + 72° = 164°
180° - 164° = 16° (Ans)
