Write the slope-intercept form of the equation of the line through the point (-1,-5) with a slope of 5/6.

Answers

Answer:

5/6x+4 1/6=y

Step-by-step explanation:

The equation to find a slope-intercept is mx+b=y

m=slope

x=x coordinates

y=y coordinates

b= y intercept

m=5/6

x=-1

y=-5

b=4 1/6

Y intercept:

5/6(-1)+b=-5

-5/6+b=-5

b=4 1/6

However, it asks for an equation of the line, not (-1,-5), so we only need to write m and b, but not x and y.

So: 5/6x+4 1/6=y

x² - 5x = 104

x² - 5x - 104 = 0

Step-by-step explanation:

Properties of Exponents

The property called Power to a Power shows us how to simplify expressions of the type:

[tex](x^n)^m=x^{n*m}[/tex]

Similarily the property called Power of a product simplifies expressions like:

[tex](x.y)^n=x^n.y^n[/tex]

The company mentioned in the question uses the expression

[tex](2x^3)^3[/tex]

millimeters per second to calculate the maximum capacity of a photocell with an area of x^3 square millimeters.

First, use the power of a product property:

[tex](2x^3)^3=2^3\cdot (x^3)^3[/tex]

Now use the power to a power property:

[tex](2x^3)^3=2^3\cdot x^{3*3}[/tex]

Find the value of y. -6y + 14+4y=32.
A.18.
B.1.8.
C.-9.
D.9

Answers

Answer:

Step-by-step explanation:

-6y+14+4y=32
Combine the like terms together
-6y+4y+14= 32
-2y+14= 32
Move + 14 to the other side
Side changes from +14 to -14
-2y+14-14=32-14
-2y= 18
Divide both sides by -2
-2y/-2=18/-2
y= -8

If p is directly proportional to q, and p=9 when q=7.5, find q when p=24.

Answers

Solution and Explanation:

If [tex]p[/tex] and [tex]q[/tex] are directly proportional, then they must have a common scalar.

To find [tex]q[/tex] we must first find its scalar. If we let [tex]a[/tex] be the scalar we can form the equation, [tex]ap = q[/tex].

We are given the information that if [tex]q = 7.5[/tex] then [tex]p = 9[/tex]. We can use that in finding the scalar.

[tex]a \times 9 = 7.5 \\ \frac{a \times 9}{9} = \frac{7.5}{9} \\ a = \frac{75}{90} \\ a = \frac{15}{18}[/tex]

Now we can solve for [tex]q[/tex] when [tex]p = 24[/tex] knowing that our scalar is [tex]\frac{15}{18}\\[/tex].

[tex]ap = q \\ \frac{15}{18} \times 24 = q \\ \frac{360}{18} = q \\ 20 = q[/tex]

Answer:

[tex]q = 20[/tex] when [tex]p = 24[/tex]

Answers

So when you divide by powers of ten (ten times itself some number of times, like ten, one hundred, one thousand, etc.), the decimal moves to the left. For each power of ten, you move one place to the left. So if you divided a number by one hundred (10^2 or 10*10), you would move two places to the left.

What is an equation of the line perpendicular to the one shown that passes through (-3,-4)?

Answers

Answer:

D. [tex] y = \frac{2}{3}x - 2 [/tex]

Step-by-step explanation:

To find the equation of the line that is perpendicular to the one shown on the graph, which passes through (-3, -4) we need to find the slope of the line, m, and the y-intercept, b.

The equation would be in the slope-intercept form given as y = mx + b.

The slope of the line would be the negative reciprocal of the slope of the line shown on the graph.

So, first, find the slope of the line shown in the graph using the points on the line, (0, 3) and (4, -3):

[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-3 - 3}{4 - 0} = \frac{-6}{4} = -\frac{3}{2} [/tex]

Since the slope of the line shown on the graph is -³/2, therefore the slope of the line that is perpendicular to the line shown would be the negative reciprocal of -³/2. Negative reciprocal of -³/2 is ⅔.

Therefore, the slope, m, of the line that is perpendicular to the line shown is ⅔.

Let's find its y-intercept using the point given, (-3, -4) that the line passes through and its slope, m = ⅔.

Substitute m = ⅔, x = -3 and y = -4 in y = mx + b, to find b.

-4 = ⅔(-3) + b

-4 = -2 + b

Add 2 to both side

-4 + 2 = b

-2 = b

b = -2

Substitute m = ⅔, and b = -2 in y = mx + b.

The equation of the line would be:

[tex] y = \frac{2}{3}x +(-2) [/tex]

[tex] y = \frac{2}{3}x - 2 [/tex]
