Answer:

y = 2x

Step-by-step explanation:

y=mx+b

m=2

x=2

y=4

4=2*2 + b

b = 4 - 4

b = 0

y = 2x

Can you figure out the formula

puteri [66]

If "a" and "b" are two values of x-coordinate, and "m" is the midpoint between them, it means the distance from one end to the midpoint is the same as the distance from the midpoint to the other end

... a-m = m-b

When we add m+b to this equation, we get

... a+b = 2m

Solving for m gives

... m = (a+b)/2

This applies to y-coordinates as well. So ...

... The midpoint between (x1, y1) and (x2, y2) is ((x1+x2)/2, (y1+y2)/2)

_____

Jennifer had (x1, y1) = (-4, 10) and (x2, y2) = (-2, 6). So her calculation would be

... midpoint = ((-4-2)/2, (10+6)/2) = (-6/2, 16/2) = (-3, 8)

Brandon had (x1, y1) = (9, -4) and (x2, y2) = (-12, 8). So his calculation would be

... midpoint = ((9-12)/2, (-4+8)/2) = (-3/2, 4/2) = (-1.5, 2)

Find the missing angle measures in the given rhombus.

jeyben [28]

Answer:

$(1) = 38\°$

$(2) = 90\°$

$(3) = 90\°$

$(4) = 38\°$

Step-by-step explanation:

The diagonals of a rhombus are perpendicular to each other, so angles (2) and (3) are equal 90°.

To find angle (1), we can use the sum of internal angles in the left triangle with angles 52°, (1), and (2):

$52 + (1) + (2) = 180$

$(1) = 180 - 52 - 90$

$(1) = 38\°$

The diagonals of a rhombus bisects the angles, to the angle next to the angle of 52° is also 52°, then, in the upper triangle, we have:

$52 + (4) + 90 = 180$

$(4) = 38\°$

Mariulka [41]

Answer:

$\displaystyle y = 4x - 1$

Step-by-step explanation:

7 = 4[2] + b

$\displaystyle -1 = b \\ \\ y = 4x - 1$

* Parallel Lines have SIMILAR RATE OF CHANGES [SLOPES], so 4 remains the way it is.

Select the correct answer. Find the solution(s) for x in the equation below. x2-9x+20=0

trasher [3.6K]

Step-by-step explanation:

Given

x² - 9x + 20 = 0

x² - ( 4 + 5) x + 20 = 0

x² - 4x - 5x + 20 = 0

x ( x - 4 ) - 5 (x - 4 ) = 0

(x - 4 ) ( x - 5 ) = 0

Either

x - 4 =0

x = 4

x - 5 =0

x = 5

x = 4 and 5

Hope it will help :)
