Rewrite in simplest terms: 5(0.9m+0.5)-3(0.4m+0.7)
hram777 [196]

Answer:

3.3m+1.4

Step-by-step explanation:

Multiply 5 and 0.9m

Multiply 5 and 0.5

5 times 0.9m is 4.5m

5 times 0.5 is 2.5

Multiply -3 and 0.4m

Multiply -3 and 0.7

-3 times 0.4m is -1.2m

-3 times -.7 is -2.1

4.5m+ 2.5 -1.2m-2.1

Which is 3.3m+1.4

Hope this helps!

Given the equation Y -3 equals 1/2 (X +6 )in point slope form identify the equation of the same line in standard form
liberstina [14]

The standard form of a line:

Ax+By=C

We have the equation of a line in the slope-point form:

y-3=\dfrac{1}{2}(x+6)      use distributive property

y-3=\dfrac{1}{2}x+3       add 3 to both sides

y=\dfrac{1}{2}x+6        multiply both sides by 2

2y=x+12       subtract x from both sides

-x+2y=12      change the signs

x-2y=-12

In the distance, an airplane is taking off. As it ascends during take-off, it makes a slanted line that cuts through the rainbow
irakobra [83]

Answer:

The equation of the parabola is given to be : y = -x² + 36

So, the airplane will cut the rainbow if the graph of the equation of airplane intersects the graph of rainbow.

Now, to find the equation of airplane :

The points through which airplane passes are : (1,0) and (0,2)

⇒ Equation : 2x + y = 2

This equation will  intersect the parabola at exactly two points.

And the points are the solution of these two equation :

(-4.916,11.832) and (6.916,-11.832)

The required table is :

x        -4.916       11.832

y         6.916      -11.832
