You start by finding two points on the line. In this case, (-4,1) and (-2,2) will do.

To get from (-4,1) to (-2,2), you need to go “up 1, right 2” which gives you a slope of m = 1/2

Next you need the b-value, which comes from the y-intercept of (0,3). The b-value is 3.

Putting the slope and b-value into y=mx+b, you have y = 1/2 x + 3.

A square has a perimeter of 12 yd. What is the length of each side?

Lena [83]

Answer:

Length of side of square is 3 yd.

$~$

Step-by-step explanation:

Let the side of square be 's'. We know that Perimeter of square is 4 × Side. By substituting values in the formula we can find the required side.

$~$

$:\implies \sf 4 × s=Perimeter \: of \: square$

$~$

$:\implies \sf \: \: \: 4 × s = 12$

$~$

$:\implies \sf \: \: \: s = \dfrac{12}{4}$

$~$

$:\implies \bf \: \: \: Side = 3 yd.$

$~$

$\therefore \:$ Length of side of square is 3 yd.

If f(x)=4x-1 and g(x)=x^2+7 ,find G(f(x))

frutty [35]

Answer:

$g(f(x))=(4x-1)^2+7=16\,x^2-8x+8$

Step-by-step explanation:

Given:

$f(x)=4x-1\\and \\g(x)=x^2+7$

Then the composition of functions:

$g(f(x))=g(4x-1)=(4x-1)^2+7= (16\,x^2-8x+1)+7=16\,x^2-8x+8$

where we have written the final functional expression in its standard form.

Please please plz plz plz plz plz plz plz plz plz please please help me plz

Xelga [282]

To solve for these, we will use formulas and convertions as we go.
For 1:
We are looking for kg (kilograms) to g (grams). 1 g = 0.001 kg.
We have 2.5 kg. This means we must multiply 2.5 by 1,000.
2.5 x 1,000 = 2,500.
1.) is 2,500 grams.
For 2:
This problem has multiple steps, but we will successfully solve it. As of now, we have yards. There are 3 feet in a yard, and 12 inches in 1 ft. We will convert yards to feet, and then feet to inches.
500x3 = 1500, 1500 x 12 = 18,000.
2.) is 18,000 inches.
For 3:
There are 2,000 pounds in 1 ton. Using this, we can determine how many tons we have.
7,000/2,000 = 3.5
3.) is 3.5 tons.
I hope this helps!
