A larger number is 2 more than 4 times a smaller number. The larger number is also 8 more than 2 times the smaller number.
pogonyaev

Answer:

see the explanation

Step-by-step explanation:

Let

x ----> the smaller number

y ----> the larger number

we know that

A larger number is 2 more than 4 times a smaller number

<u><em>Identify the key words</em></u>

is (=)---> equal

more (+) ---> addition

times (*) ---> multiplication

That means

The larger number y is equal  to multiply the smaller number x by 4 and then adds 2

so

y=4x+2 ----> equation A

The larger number is also 8 more than 2 times the smaller number

<u><em>Identify the key words</em></u>

is (=)---> equal

more (+) ---> addition

times (*) ---> multiplication

That means

The larger number y is equal  to multiply the smaller number x by 2 and then adds 8

so

y=2x+8 ----> equation B

Solve the system of equations by substitution

equate equation A and equation B

4x+2=2x+8

4x-2x=8-2\\2x=6\\x=3

Find the value of y

substitute the value of x in equation A or equation B

y=4(3)+2=14

therefore

The smaller number is 3 and the larger number is 14

Solve the equation (x-4)(2x+3) = 4​
Marina CMI [18]

Answer:

(x-4.34)(x+1.84)=0

Step-by-step explanation:

2x^2 -5x-16=0

delta=

25  + 4 \times 2 \times 16  = 153

x1,2=

(5 +  \sqrt{153} ) \div 4 = 4.34  \\ (5 -  \sqrt{153} ) \div 4 =  - 1 .84

if you subtract the least integer from the greatest integer and divide the difference by 3 the quotient is 5
vodomira [7]
Let a and b be integers and b>a, then we can say:

(b-a)/3=5  now multiply both sides by 3

b-a=15

b=15+a

So there are infinitely many pairs of integers that satisfy the conditions given in the problem. For any value a, b will be 15 units greater.

Which shows the correct substitution of the values a, b, and c from the equation 0 = – 3x2 – 2x + 6 into the quadratic formula?
lbvjy [14]

Answer:

x = StartFraction negative

(negative 2) plus or minus StartRoot (negative 2) squared minus 4 (negative 3)(6) EndRoot Over 2(negative 3) EndFraction

Step-by-step explanation:

0 = – 3x2 – 2x + 6

It can still be written as

– 3x2 – 2x + 6 =0

Quadratic formula=

-b+or-√b^2-4ac/2a

Where

a=-3

b=-2

c=6

x= -(-2)+ or-√(-2)^2-4(-3)(6)/2(-3)

x = StartFraction negative

(negative 2) plus or minus StartRoot (negative 2) squared minus 4 (negative 3)(6) EndRoot Over 2(negative 3) EndFraction
