Write an equation in slope intercept form that goes through (-1,6) and (3,-2)

Answers

Answer 1
Answer:

First, we need to use slope formula* to find the slope.

[tex]m = \frac{-2 - 6}{3 - (-1)} = \frac{-8}{4} = -2[/tex]

Second, we use the slope we found and ONE of the 2 points listed and plug it into slope-intercept form** to solve for b.

Here is what we have so far:

[tex]m = -2[/tex]

I'm going to use this point:

[tex]x = 3[/tex][tex]y = -2[/tex]

Here is how to find b:

[tex]-2 = -2(3) + b\\\\-2 = -6 + b\\\\4 = b[/tex]

Finally, we put all of it together and we have our equation.

[tex]y = -2x + b[/tex]

*Slope formula: m = y₂ - y₁/x₂ - x₁

**Slope-intercept form: y = mx + b

Step-by-step explanation:

Proportional Variables

Two variables x,y are proportional if one of them can be calculated as the other variable time a fixed constant:

y = k.x

Or, equivalently:

k = y/x

k is called the constant of proportionality.

The table gives three points: (13,45.5) (14,49) (15,52.5)

To find out if the values correspond to a proportional relationship, we find the value of k for each pair:

k = 45.5 / 13 = 3.5

k = 49 / 14 = 3.5

k = 52.5 / 15 = 3.5

Since the value of k is the same for all the points, we conclude the table shows a direct proportional relationship and the constant of proportionality is 3.5

Answer:

f(x) = 2x^2 + 12x +10

Step by step solution:

x = 1 x = 5 y = 10

f(x) = a(x+1)(x+5)

f(0) = a(1)(5) = 10

5a = 10

Divide by 5

a = 2

f(x)= 2(x+1)(x+5)

f(x) = 2(x^2 +6x +5)

f(x) = 2x^2 + 12x +10

Complete the real-world situation that could be modeled by the equation 150 − 8x = 170 − 12x. Xavier has $150 in his lunch account. He spends $ for lunch each day. Zack has $ in his lunch account. He spends $ each day. After how many days will the boys have the same amount of money in their accounts?

Answers

Answer:

5 days

Step-by-step explanation:

The question above is modeled by the equation :

150 − 8x = 170 − 12x.

After how many days will both have ye same amount :

Number of days = x

Collect like terms

-8x + 12x = 170 - 150

4x = 20

x = 20/4

x = 5 days

The boys will have the same amount in their account after 5 days.

Todd said, "I can solve by completing the square. If I add 444 to each side, I can rewrite the equation as (x+3)^2=12(x+3) 2 =12left parenthesis, x, plus, 3, right parenthesis, squared, equals, 12." Whose solution strategy would work? Choose 1 answer: Choose 1 answer:

Answers

Answer:

Todd's

Step-by-step explanation:

Given the expression x^2+6x+5=8, we are to determine which whether Imani or Todd method will work

Imani method might not work because he hasn't written the equation in standard form before factorizing. He should have equated the expression to zero first before factorizing and finding the zeros of the expression. The equation should have been written in the form ax²+bx+c = 0 first.

For Todd, his method will work because he used the completing the square method. The value at the right hand may not necessarily be zero before applying the rule. The idea is to make the quadratic equation complete and a perfect square.

This is achieved by adding the half of coefficient of x to both sides of the expression before simplifying.

From the expression x²+6x+5 = 8 we can see that adding 4 to both sides will make the quadratic equation on the left a perfect square.

x²+6x+5= 8

x²+6x+5+4= 8 +4

x²+6x+9 = 12

x²+3x+3x+9 = 12

x(x+3)+3(x+3) = 12

(x+3)(x+3) = 12

(x+3)² = 12

We can see that the expression at the left hand is now a perfect square. Hence Todd solution strategy will work

The answer is 46.

Step-by-step explanation:

First, you will have to add up both functions in order to find the new expression for (g + f)(a) :

g(a) + f(a) = (g + f)(a)

(g + f)(a) = 3a + 3 + 2a - 2

(g + f)(a) = 5a + 1

Next, you have to substitute a = 9 into the function :

(g + f)(9) = 5(9) + 1

(g + f)(9) = 46

That's the equation for exponential growth

a= the starting amount

r= the rate at which it is growing

x=years

with that information

a=7000

r=6% or 0.06

so y=7000(1+0.06)^x -> y=7000(1.06)^x

x=7

y=7000(1.06)^7

The diagram shows a sector of a circle radius 11 cm.
Show that the perimeter of the sector
is greater than 47.5 cm.

135°
11 cm

Answers

Answer:

Perimeter of sector is 47.93 cm which is greater than 47.5 cm

Step-by-step explanation:

Mathematically, the perimeter of a sector is length of the arc plus 2 radii

The length of the arc is;

theta/360 * 2 * pi * r

where theta is the angle subtended by the arc at the center of the circle

Thus, we have

135/360 * 2 * 22/7 * 11 = 25.93

Add 2 radii = 25.93 + 2(11) = 47.93 cm

This is greater than what we are asked to calculate and thus we have shown what we are asked to show

Answer:

47.9cm>47.5cm

Step-by-step explanation:

135(angle) /360 x 2 pi r (to give arc of the sector)

135/360 x 2 x 3.142 x 11 = 25.92cm

add 11 + 11 (radius)

25.92 + 22= 47.9cm

Answer:

Undefined

Step-by-step explanation:

To find slope, you need the difference of y over the difference of x.

For example, let's use (-8,8) and (-8,3).

Difference of y: 8-3

Difference of x: -8-(-8) (Note that the order of the x values must be the same as the order of the corresponding y values of the coordinate)

(8-3)/(-8+8)

= 5/0

Now, we see that we have to divide by 0, except it's impossible to divide by 0, so the slope is left as undefined.

Step-by-step explanation:

Answer:

x = 22/3, x=14

Step-by-step explanation:

Start by isolating whatever is in the absolute value sign; in this case divide either side by 4

4|1-3/4x + 7| =10,

-----------------   ----

        4            4

|1-3/4x + 7| = 10/4 = 5/2,

now if we apply the absolute value rule we know that 1-3/4x + 7 will be equal to -5/2, and 5/2

1-3/4x + 7 = 5/2 and 1-3/4x + 7 = -5/2

-3/4x + 8 = 5/2,

-3/4x=5/2-8,

-3/4x = 5/2-16/2,

-3/4x = -11/2,

x = -11/2*-4/3 = 44/6 = 22/3

-3/4x+8 = -5/2

-3/4x = -5/2-8

-3/4x = -5/2-16/2

-3/4x = -21/2

x = -21/2*-4/3 = 82/6 = 14
