Which equation represents the line that passes through (-3,5) and is parallel to the graph of y= -2/3x+5
Nostrana [21]
Parallel to the graph of y = -2/3x + 5
means that it has the same slope

Rewrite
y = -2/3x + b
plug in the given coordinates to solve for b
5 = -2/3(-3) + b
5 = 2 + b
subtract 2 from both sides
3 = b

plug that back into the equation
y = -2/3x + b
y = -2/3x + 3

The answer is <span>B. y= -2/3x+3</span>

This line is parallel to y = -2/3x + 5 and it passes the point (3, 5).

Hope this helps :)

Work out the percentage increase of 42 to 186.
Elza [17]

Answer:

 342.85714 %

Step-by-step explanation:

Percentage increase is  given by

 increase= (new - original)/ original * 100 %

The new is 186 and the original is 42

                = (186 - 42)/ 42 * 100 %

                 =144/42* 100 %

                 =3.42857 * 100%

                   =342.85714 %

ASHA 777 [7]

Answer:

X=55° Y=35°

Step-by-step explanation:

X+Y=90°

Y= x-20

(X-20)+X=90°

2X-20=90°

2X=110°

X=55°

55°+Y=90°

Y=35°

Find the equation of the line using the point-slope formula. Write the final equation using slope-intercept form. (1,2) with a s
Naily [24]

Answer:

y-2=\displaystyle-\frac{6}{7}(x-1)

or

y=\displaystyle-\frac{6}{7}x+\frac{20}{7}

Step-by-step explanation:

Hi there!

Point-slope form: y-y_1=m(x-x_1) where <em>m</em> is the slope and (x_1,y_1) is a point that falls on the line

Plug in the slope, -6/7, and the given point, (1,2):

y-2=\displaystyle-\frac{6}{7}(x-1)

To write the equation in slope-intercept form, isolate y:

y-2=\displaystyle-\frac{6}{7}(x-1)\\\\y-2=\displaystyle-\frac{6}{7}x+\frac{6}{7}\\\\y=\displaystyle-\frac{6}{7}x+\frac{6}{7}+2\\\\y=\displaystyle-\frac{6}{7}x+\frac{20}{7}

I hope this helps!

PLEASE HELP!!

You can use the Pythagorean Theorem to find the length of the third side AB (Identified as "x" in the figure attached in the problem), which says that in a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the legs:
a² = b²+c²
As we can see the figure, the triangle does not have an angle of 90°, but it can be divided into two equal parts, leaving two triangles with a right angle. We already have the values of the hypotenuse and a leg in triangle "A" , so we can find the value of the other leg:
b = √(a²-c²) b = √(10²-4²) b = 9.16
With these values, we can find the hypotenuse in the triangle "B": x = √b²+c² x = √(9.16)²+(4)² x = 10
