Find you equation of the line shown
Answer:
y=x+6
Step-by-step explanation:
(0,6). y=mx+b or 6=1 × 0+b, or solving for b: b=6-(1)(0). b=6.
(1,7). y=mx+b or 7=1 × 1+b, or solving for b: b=7-(1)(1). b=6.
I inputted two points from the graph and solved them.
Hence the equation would be y=x+6
Answer:
y= x + 6
Step-by-step explanation:
For here we are looking for y= mx +b.
For the slope, It is y= 4/4.
That can be simplified into 1x or x.
Then look at where it contacts the y axis. It is at six. Plug all that in to get
y= x + 6

A polygon has vertices at (4, 1), (4,7), (10, 7) and (10, 1). How does the perimeter of
the polygon change if each coordinate is multiplied by 3?
The perimeter goes from 24 to 72
24*3 = 72
==========================================================
Explanation:
I recommend plotting the four points on the same xy grid system. Connect the points with segments to form a rectangle. This rectangle is also a square. You should find that each side of the square is 6 units long, so the perimeter is 4*6 = 24 units.
If we multiply each coordinate by 3, then that will make each side length 3 times longer than before. That means each side is now 6*3 = 18 units long. The perimeter is 4*18 = 72 units.
Note how the jump from 24 to 72 is "times 3". Therefore, the scale factor of 3 will make the new perimeter 3 times longer compared to the old perimeter.
Simplify the expression to a polynomial in standard form:
(3x − 2)(x^2 – 2x + 1)
Answer:
The polynomial in the standard form of this expression would be [tex]3x^3-8x^2+7x-2[/tex].
Step-by-step explanation:
If you are trying to expand a binomial multiplied by a trinomial, you need to multiply each term from the binomial to each term in the trinomial. In this case, [tex](3x-2)(x^2-2x+1)=3x^3-6x^2+3x-2x^2+4x-2=3x^3-8x^2+7x-2[/tex], so that will be the answer.
Which is the perimeter of the shape? (1 point)
Answer:
22
Step-by-step explanation:
4 x 2 + 7 x 2 = 22
Answer: 22
Step-by-step explanation:
to find perimeter you have to add up all the sides around a shape.
7 + 7 + 4 + 4 = 22
OR
7+7= 14
4 + 4 = 8
14 + 8 = 22

Respuesta:
La proporción común del término puede ser 1/5
Explicación paso a paso:

Does anyone know how to solve this?
Answer:
17 meters
Step-by-step explanation:
Plug x=30 into the equation H(x) = 11 + 0.2x
H(30) = 11 + 0.2 * 30
H(30) = 11 + 6
H(30) = 17
Thus, the answer is 17 meters.

Two geometry questions in the attached photos - If I have a line, do I have a plane? & If I have three points, do I always have a plane?
Answer:
18) A: only if you have an additional point not on the line.
19) D: No, because all the points may be on the same line.
Step-by-step explanation:
There are basically 4 ways we can determine a plane and they are;
- When we have three non - collinear points: What this means is that if we have three points that are not on one line, then it means that only one particular plane can pass through those points.
- When we have a line and a point that's not on the line
- When we have two lines that intersect each other.
- When we have two lines that are parallel to each other.
From the four conditions above, we can now answer the question;
18) You can only have a plane if there is an additional point not on the line.
Option A
19) Having just three points may not always be sufficient to have a plane because it's possible that the three points may be on the same line which is not a condition for a plane. Thus, option D is correct.

Can someone prove 1+cosx/1+secx=cosx
with all the steps included?
Please and thank you.
Answer:
Proved , since LHS= RHS
Step-by-step explanation:
We need to prove the given expression ,
=> 1 + cos x / 1 + sec x = cos x
Simplifying LHS.=> 1 + cos (x) / 1 + sec (x)
=> 1 + cos (x) / 1 + 1/cos (x)
=> 1 + cos (x) ÷ 1 + cos(x) / cos (x)
=> 1 + cos (x) × cos(x) / { 1 + cos (x) }
1 + cos (x) gets cancelled . So we are finally left out with ,=> cos (x)
= RHS

For triangle
side1=9ft
side2=10ft
base[b]=11ft
height[h]=7.7ft
and for rectangle
length [l]=3ft
wide [w]=9ft
Now
total surface area=lateral surface area +2curved surface area
=perimeter of triangle×length +2area of triangle
=(9+10+11)×3+2×1/2×2(½×b*h)
=90+11×7.7
=174.7
=175ft²is a required answer.
Roberto debe leer un libro que contiene 340 páginas en 4 días por lo cual planea la siguiente distribución: el primer día 1/5 de las páginas del libro, el segundo 1/4 de lo que queda por leer y el tercero 1/6 del resto. ¿Cuántas páginas le quedan por leer a Roberto en el cuarto día?
Answer:
170 pages
Step-by-step explanation:
Roberto must read a book that contains 340 pages in 4 days for which he plans the following distribution
The number of pages he read for the first day :
The first day 1/5 of the pages of the book
This is calculated as:
1/5 × 340 pages
= 68 pages
For the second day:
The second 1/4 of what remains to be read
The number of pages remaining after the first day is calculated as:
340 - 68 = 272 pages
Hence, the number of pages read on the second day is
1/4 × 272 pages
= 68 pages
For the third day
One the third day, 1/6 of the rest was read.
The number of pages remaining after the first day is calculated as:
272 - 68 = 204 pages
Hence, the number of pages read on the third day is
1/6 × 204 pages
= 34 pages
Therefore, the number of pages Roberto has to read on the fourth day is calculated as:
340 pages - (68 + 68 + 34)pages
340 pages - 170 pages
= 170 pages

What are permutations?The different arrangements which can be made out of a given number of objects by taking out some or all at a time are called permutations.
Suppose there are n items.
Suppose we have

Find the missing dimension of the triangle. Area =14ft^2, height =6ft, base= ? Find the base.
Answer: b = 14/3 = 4.667 feet
The decimal value is approximate. In reality the 6's go on forever. Round that however you need to.
================================================
Work Shown:
b = unknown base
h = height = 6 ft
A = area = 14 sq ft
A = b*h/2
14 = b*6/2
14 = b*3
14 = 3b
3b = 14
b = 14/3
This approximates to 14/3 = 4.667 ft

Answer:
d. 89°
Step-by-step explanation:
The given measure of the angles formed are;
m∠AED = 48°, m[tex]\widehat{AG}[/tex] = 175°
According to circle theorem, the angle formed by a chord and a tangent of a circle is given by half of the measure of the arc intercepted by the chord in the direction of the angle;
Therefore;
m∠AED = (1/2) × m[tex]\widehat{ABE}[/tex] = 48°
∴ m[tex]\widehat{ABE}[/tex] = 2 × 48° = 96°
m∠AEF = (1/2) × m[tex]\widehat{AGE}[/tex]
m[tex]\widehat{ABE}[/tex] + m[tex]\widehat{AGE}[/tex] = 360° (angle round a circle)
∴ m[tex]\widehat{AGE}[/tex] = 360° - m[tex]\widehat{ABE}[/tex] = 360° - 96° = 264°
m[tex]\widehat{AGE}[/tex] = m[tex]\widehat{AG}[/tex] + m[tex]\widehat{EG}[/tex]
∴ m[tex]\widehat{EG}[/tex] = m[tex]\widehat{AGE}[/tex] - m[tex]\widehat{AG}[/tex] = 264° - 175° = 89°
m[tex]\widehat{EG}[/tex] = 89°.
