Answer:
A proportion is simply a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d. The following proportion is read as "twenty is to twenty-five as four is to five."
Step-by-step explanation:
Answer:
A proportion is simply a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d. Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fraction in it’s simplest form. Another way is to see if the numbers in the ratios are factors or multiples of each other. For example, 10:5 and 30:15. 10:15= 10/5 and 30:15= 30/15. Then you put it in simple form. 10/5 = 2 and
30/15 = 2. Therefore 10:5 and 30:15 are proportional.

diagram of ABCD to find m
Answer:
since the pairs of opposite lines in the diagram are parallel the measurement of B is also 63
to fine A and C simply subtract 180 - 63 which gives us 117 so
A = 117
B = 63
C = 117
D = 63

What is the y-intercept when a line has a slope of 3 and passes through
the point (2, 7)?
Answer:
The y-intercept is (0,1)
Step-by-step explanation:
So, first you need to find the equation! Point slope form is (y-y1)=m(x-x1).
Plug the numbers in and you get (y-7)=3(x-2). Now, the y intercept is where x=0, so plug in zero for x.
y-7=3(0-2)
y-7=3(-2)
y-7= -6.
-6+7= 1, so y=1
The ordered pair is then (0,1). Hope this was useful :)

Write your answer in simplest radical form.
units
Answer:
c = 3[tex]\sqrt{6}[/tex]
Step-by-step explanation:
triangle is right isosceles so both sides equal 3[tex]\sqrt{3}[/tex]
can use pythagorean theorem which is square each leg and set it equal to the hypotenuse (side 'c') squared
(3[tex]\sqrt{3}[/tex])^2 + (3[tex]\sqrt{3}[/tex])^2 = c^2
(9x3) + (9x3) = c^2
27 + 27 = c^2
54 = c^2
c = [tex]\sqrt{54}[/tex]
simplify [tex]\sqrt{54}[/tex] to equal = [tex]\sqrt{9}[/tex] x [tex]\sqrt{6}[/tex] which simplies to 3[tex]\sqrt{6}[/tex]

so put all of those equal to 540
need to find x first
540=132+(4x-10)+(5x-11)+128+(4x+2)

In linear equation, 1:16 the perimeter and area of the mat for scale factors.
What in mathematics is a linear equation?
A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.
Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.
Perimeter Ratio for scale factor 2: (picture)1:2 (mat)1:2
Ratio for scale factor 3: (pic) 1:3 (mat) 1:3
Ratio for scale factor 4: (pic) 1:4 (mat) 1:4
Area Ratio for scale factor 2: (pic &mat) 1:4
Ratio for scale factor 3:(pic&mat) 1:9

(x – 4)2 = -9 has no real solution
Answer:
x = -1/2
Step-by-step explanation:
(x - 4) * 2 = -9
Divide both sides by 2:
x - 4 = - 9 / 2
Add 4 to both sides:
x = - 1 / 2.

Answer: 6, -1
Step-by-step explanation:
1. Look at both of the lines. (Blue and purple)
2. Which dot connects to both lines? (The dot which is green)
3. Since they’re together, that’s the answer.
4. Find the coordinates.
5. Go to “0” and go left until you hit the green dot area. (6 as X axis)
6. Go down to the green dot to find the Y coordinate. (-1 as Y axis)
7. You got the answer (6, -1) !
Solve the system of equations.
2x+8y=6
-5x-20y+-15
Answer:
2x+8y=6
Step 1: Add -8y to both sides.
2x+8y+−8y=6+−8y
2x=−8y+6
Step 2: Divide both sides by 2
[tex]\frac{2x}{2}[/tex] = [tex]\frac{-8y+6}{2}[/tex]
x=−4y+3

Write an equation in point-slope form of the line that passes through the point (5,-12) and has a slope of m= -2/5
I hope that it will be help full for u
Step-by-step explanation:As we know point slope form ,
(Y- Y1) = m (X- X1)
As given data ,
m = -2/5
(X1,Y1) = (5, -12)
X1= 5 , Y1= -12
putt in the above equation these values, we get
Y-(-12) = (-2/5) ( X-5)
Y+12=(-2/5)X+2
Y= (-2/5)X -10 Ans ,ITs also an answer but if you want to simplify more ,taking LCM we get
Y = ((-2)X-50)/5
5Y=(-2)X-50 Ansanyone know what the answer to this is i’m really bad in slope intercept form.
