Knowing your units is helpful because there are a lot of different units like units of capacity or units of the metric system

Lets say you're building something you have to know the units to see oh ok it takes this many units to build the room. Units will be the inside and out. You will easily know what it's gonna be to build

One linear equation is defined by points (1, 6) and (3, 7), while the other is defined by points (3, 6) and (5, 8). Which point
zysi [14]
So we need to find the two lines...y=mx+b where m is the slope and b is the y-intercept.

m=(dy/dx)=(7-6)/(3-1)=1/2 so

y=x/2+b, now I'll use (1,6) to solve for b

6=1/2+b, b=5 1/2=11/2 so

y1=(x+11)/2

now the other line...

m=(8-6)/(5-3)=2/2=1

y2=x+b, using point (3,6) we solve for b

6=3+b, b=3 so

y2=x+3

Since this is just two lines they will only intersect at a single point and when they do, y=y so we can say:

x+3=(x+11)/2

2x+6=x+11

x+6=11

x=5, now use either line to solve for the corresponding y value...

y2=x+3 becomes y=5+3=8 so the solution to this system is the point:

(5,8)

Write the equation of a line with a slope of –1 and a y-intercept of –6.
vazorg [7]

For this case the generic equation of the line is given by:

y = mx + b

Where,

m: slope of the line

b: intersection with the y axis

For this case we have:

m = -1\\b = -6

Therefore, substituting values in the generic equation we have:

y = -x - 6

Answer:

The equation of the line is:

y = -x - 6

option 1

 In the expression 9z^4-8+15(y^3+6), name the two factors of the term 15(y^3+6)
natulia [17]
<h3>The two factors are 15 and y^3+6</h3>

Factors multiply to get a product. You can take this process in reverse.

As another example, the number 12 factors into 3*4, where 3 and 4 are the two factors. This idea applies to both numbers and variable expressions as well.

Subtract.<br><br> −2.08−(−4.49)<br><br> Enter your answer in the box.
yan [13]

Answer:

2.41

Step-by-step explanation:

Two negative signs are equal to a plus sign.

Ex: 1 - -1 is 2 because 1 - 1 is 0 and then another reverse would be 2

So:

-2.08 + 4.49 = Positive

4.49 - 2.08 = 2.41

Does the function satisfy the hypotheses of the Mean Value Theorem on the given interval? f(x) = 4x2 − 3x + 2, [0, 2] Yes, it do
boyakko [2]

Answer:

a) Yes, f is continuous on [0, 2] and differentiable on (0, 2) since polynomials are continuous and differentiable on R

b) c=1

Step-by-step explanation:

a)The given function is;

f(x)=4x^2-3x+2

For this function to satisfy the Mean Value Theorem, it must;

i) be continuous on [0,2]

ii)be differentiable on (0,2)

Since f(x)=4x^2-3x+2 is a polynomial function, it is continuous on [0,2] and differentiable on (0,2) because polynomial functions are continuous and differentiable on the entire real numbers.

b)

Since the above two hypotheses are satisfied,it implies that, there is a certain c\in (0,2) such that; f'(c)=\frac{f(2)-f(0)}{2-0}

f'(x)=8x-3

8c-3=\frac{12-2}{2}

8c-3=\frac{10}{2}

8c-3=5

8c=5+3

8c=8

c=1

Therefore the number that satisfies the conclusion of the Mean Value Theorem is c=1.

We can see from the graph that at x=1, the secant line is parallel to the tangent on the interval [0,2]
