2x -3y=4:(2,) fill the other coordinates
JulsSmile [24]

Answer:

x = 2 + 1.5y

Step-by-step explanation:

Simplifying

<em>2x + -3y = 4</em>

Solving

<em>2x + -3y = 4</em>

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3y' to each side of the equation.

<em>2x + -3y + 3y = 4 + 3y</em>

Combine like terms: -3y + 3y = 0

<em>2x + 0 = 4 + 3y</em>

<em>2x = 4 + 3y</em>

Divide each side by '2'.

<em>x = 2 + 1.5y</em>

Simplifying

<em>x = 2 + 1.5y</em>

Through: (-3,-5), perp. to y=-1/3x+2
lara [203]
Y = -1/3x + 2.....the slope here is -1/3. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal, flip the slope and change the sign. So the slope is -1/3.....flip it and it becomes - 3/1....change the sign and it becomes 3/1 or just 3. So ur perpendicular line will have a slope of 3.

y = mx + b
slope(m) = 3
(-3,-5)....x = -3 and y = -5
now sub into the formula and find b, the y int
-5 = 3(-3) + b
-5 = -9 + b
-5 + 9 = b
4 = b
so ur perpendicular equation is : y = 3x + 4 <===

Please I have a 50% in this class ​
Sonbull [250]
I can’t solve them all for you, but I can teach you how repeating decimals work!

For example, 1. 0.3 with a line over the three means that the three repeats forever, so it’s equivalent to 0.333333333333….

Another example is 4, since it only repeats the number that has the line over it, it is equal to 0.025555555…

Hope this helps ☺️

What is GE ?<br><br> Enter your answer in the box.<br><br><br> units
IRISSAK [1]

<u>Answer-</u>

<em>The length of GE is </em><em>10 units.</em>

<u>Solution-</u>

Mid-Point Theorem-

The line segment connecting the midpoints of  two sides of a triangle is parallel to the third side and is congruent to one half of the third side.

As given,

EX = XF, so X is the mid point of EF

GY = YF, so Y is the mid point of GF

Hence, XY is the line segment connecting the midpoints of two sides of a triangle.

Applying the theorem,

GE = 2XY = 2×5 = 10 units

Ten members of Balin’s soccer team ran warm ups for practice. Each member ran the same distance. Their combined distance was 5/6
taurus [48]

Answer:

Each of the player ran (5/60) of a mile = 0.08 miles.

Step-by-step explanation:

Let each of the member of Soccer team ran  k miles.

Hence, the distance ran by the team of  10 members ran =  

k+ k+ k.... 10 times =  10 k

Now, the total distance covered  was  (5/6) of a mile.

⇒ 10 k =\frac{5}{6}  mile

or, k = \frac{5}{6 \times 10}  mile

or, k = 0.08 miles

⇒

Balin wrote the expression  k= 0.08 miles.

Hence, each of the player ran (5/60) of a mile = 0.08 miles.
