Twice the difference of a number and 3 equals 2 use the variable c for the unknown number.

Lesechka [4]

The number is 4

Step-by-step explanation:

First of all we have to convert the given statement in mathematical form.

Let c be the number then according to given statement

$2(c-3) = 2$

We have to isolate the variable in the equation

Dividing both sides by 2

$\frac{2(c-3)}{2} = \frac{2}{2}\\c-3 = 1$

Adding 3 on both sides

$c-3+3 = 1+3\\c = 4$

Hence,

The number is 4

What’s a larger number is two less than four times a smaller. if the sum of the number is 18

s344n2d4d5 [400]

Let x be the larger number and y be the smaller number.
Using the given info, we get
x = 4y - 2
We also know that
x + y = 18
Substitute x = 4y -2 into x + y = 18
(4y -2) +y = 18
5y - 2 = 18
5y = 20
y = 4
Enter this value into x = 4y - 2
x = 4(4) - 2
x = 14
The larger number is 14 and the smaller one is 4.

Answer:

$\large\boxed{D\left(0,\ -\dfrac{20}{3}\right),\ \dfrac{2}{3}}$

Step-by-step explanation:

$\triangle FOD\sim\triangle HOG,\ \text{therefore the sides are in proportion:}\\\\\dfrac{OF}{OD}=\dfrac{OH}{OG}\\\\\text{We have}\\\\OF=4,\ \ OH=6,\ OG=10\\\\\text{Substitute:}\\\\\dfrac{4}{OD}=\dfrac{6}{10}\qquad\text{cross multiply}\\\\6OD=(4)(10)\\\\6OD=40\qquad\text{divide both sides by 6}\\\\OD=\dfrac{40}{6}\\\\OD=\dfrac{20}{3}\\\\\text{Therefore}\ D\left(0,\ -\dfrac{20}{3}\right).\\\\\text{The scale factor:}\ \dfrac{OF}{OH}=\dfrac{4}{6}=\dfrac{2}{3}$

For all the values of x,<br> f(x)=x²+3 g(x)=2x-1 <br> a) find fg(2) <br> b) find gf(2)

erik [133]

Answer:

12 and 13

Step-by-step explanation:

(a)

To evaluate f(g(2)), evaluate g(2) then use the value obtained to evaluate f(x)

g(2) = 2(2) - 1 = 4 - 1 = 3, then

f(3) = 3² + 3 = 9 + 3 = 12

--------------------------------------------

(b)

To evaluate g(f(2)), evaluate f(2) the use the value obtained to evaluate g(x)

f(2) = 2² + 3 = 4 + 3 = 7, then

g(7) = 2(7) - 1 = 14 - 1 = 13
