Factorise : x^2-9x-70 Step by Step

tensa zangetsu [6.8K]

Answer:

Step-by-step explanation:

x^2 - 9x - 70

we need to find two numbers whose sum is -9 and product id -17

The numbers are -14 and 5

By splitting the middle term,

x^2 - 14x + 5x - 70

= x ( x - 14 ) + 5 ( x - 14 )

( x + 5 ) ( x - 14 )

Hope this helps

IN the diagram Below AB is parallel to CD what is the value of y ? <br> picture is below

satela [25.4K]

Similar to the other question, because AB is parallel to CD, you know the 72º angle corresponds to the angle on top of y.

Because that angle above y and y together make a straight line (and a straight line measures 180º), you have
72 + y = 180

Solving that for y, you get y = 108º

Two planes simultaneously left the Washington and LA and headed towards each other. The distance between the cities is 2700 mile

katrin2010 [14]

Answer:

Speed of the plane from Washington: $500\ mph$

Speed of the plane from LA: $600\ mph$

Step-by-step explanation:

We need to remember that:

$d=Vt$

Where "d" is distance, "V" is speed and "t" is time.

Let be "w" the speed in mph of the plane from Washington and "l" the speed in mph of the plane from LA.

We know that the distance between the cities is 2700 miles and after they flied for 2 hours, the distance between them was 500 miles. Then we can write the following equation:

$2w + 2l + 500 = 2700$ [Equation 1]

Since the speed of the plan from LA was 100 mph faster, we can write this equation:

$l=w+100$ [Equation 2]

The steps to solve this are:

1. Substitute the Equation 2 into the Equation 1 and solve for "w":

$2w + 2(w+100) + 500 = 2700\\\\4w+200+500=2700\\\\w=\frac{2000}{4}\\\\w=500$

2. Substitute the value of "w" into the Equation 2 in order to find "l":

$l=500+100\\\\l=600$
