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

Factorise x²+8x+12plz give answer ​
larisa86 [58]

Answer:

(x+6)(x+2)

Step-by-step explanation:

we have

ax²+bx+c

To factor parabolas we need to find a number that adds to b (or 8) and mulitplies to a*c (or 12)

The numbers 6 and 2 fit this criteria which means we have

(x+6)(x+2)

5. Find the slope that intersects the x-axis at (1,3) and the y-axis at (4,7).
kotykmax [81]

For this case we have that by definition, the slope of a line is given by:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}

Where:

(x_ {1}, y_ {1})\\(x_ {2}, y_ {2})

They are two points through which the line passes.

According to the statement we have two points:

(x_ {1}, y_ {1}) :( 1,3)\\(x_ {2}, y_ {2}) :( 4,7)

Substituting we have:

m = \frac {7-3} {4-1} = \frac {4} {3}

Thus, the slope of the line is:

\frac {4} {3}

Answer:

\frac {4} {3}
