Answer:

a=2

b=5

Step-by-step explanation:

5a=2b

a=2/5b

2(2/5b) -3b= -11

4/5b-3b =-11

-2.2b=-11

b=5

5a=2*5=10

a=2

If five times the successor of a number is added to an original number the sum is 83
Alexus [3.1K]

Answer:

Let the original number be x

Successor is defined as the number which comes immediately after a particular number.

also, the  successor of a whole number is the number obtained by adding 1 to that number.

Then, the successor of a number x is, x+1

As per the given condition :

we have;

5(x+1)+x =83

Using distributive property on LHS (i.e, a\cdot(b+c)=a\cdot b+a\cdot c )

Then, we have

5x+5+x=83

Combine like terms;

6x+5=83

Subtract 5 from both the sides we get;

6x+5-5=83-5

Simplify:

6x=78

Divide both side by 6,

\frac{6x}{6} =\frac{78}{6}

Simplify:

x =13

Therefore, the original number x is, 13

Find the X-Intercepts of <br> y=-x^2-2x+1
bekas [8.4K]

Answer:

(1,0)

Step-by-step explanation:

we can't factor this so we'll use the quadratic formula

\frac{-b+\sqrt{b^2-4ac} }{2a}\\\frac{-b-\sqrt{b^2-4ac} }{2a}

(use both of them because usually there  are two zeroes)

We have

\frac{2+\sqrt{4-4}}{2}=\frac{2}{2}=1

Therefore the x intercept is just (1,0)
