Answer: f(x) = –3x + 14

Step-by-step explanation:

The point slope form of an equation is expressed as

y - y1 = m(x - x1)

The given equation is

y + 1 = –3(x – 5)

Comparing with the point slope equation,

y1 = - 1

Slope, m = - 3

x1 = 5

The equation of a straight line can also take the slope intercept form,

y = mx + c

Where

m is the slope(change in y /change in x)

c represents the intercept.

We would determine the intercept by substituting x = 5 , y = -1 , m = - 3, into y = mx + c. It becomes

- 1 = - 3 × 5 + c

- 1 = -15 + c

c = - 1 + 15 = 14

The equation becomes

y = -3x + 14

Answer:

r = $2\sqrt{5}$

$(x - 3)^{2} + ( y - 2)^{2} = 20$

Is this a live test question or a homework question?

Step-by-step explanation:

the radius is the distance between (3, 2) and (5, -2)

$r^{2}$ = ${(3 - 5)^{2} + (2 + 2)^{2} }$

= $(-2)^{2} + 4^{2}$

= 4 + 16 = 20

r = $\sqrt{20 } = 2\sqrt{5}$

Equation of circle: $(x - 3)^{2} + ( y - 2)^{2} = 20$

Solve the equation using the quadratic formula 3x^2 =2(2x+1)

Nadusha1986 [10]

Step 1: Make equation equal to Zero

3x^2 = 4x + 2

3x^2 - 4x - 2

Step 2: use equation

a= 3 b = -4 c= -2

after plugging in answer should be

(2 + or - sqrt 10) / 3

Please help. Write the equation of the graph. (Do not use spaces. Use ^ to represent exponents. Example 2^3 is 23.)

lana66690 [7]

This graph has a horizontal asymptote so it is an exponential graph. It also passes through two points (0,-2) and (1,3). The horizontal asymptote is at y=-3.
The unchanged exponential equation is y=a(b)^x +k
For exponential equations, k is always equal to the horizontal asymptote, so k=-3.
You can check this with the ordered pair (0,-2). After that plug in the other ordered pair, (1,3).
This gives you 3=a(b)^1 or 3=ab. If you know the base the answer is simple as you just solve for a.
If you don't know the base at this point you have to sort of guess. For example, let's say both a and b are whole numbers. In that case b would have to be 3, as it can't be 1 since then the answer never changes, and a is 1. Then choose an x-value and not exact corresponding y-value. In this case x=-1 and y= a bit less than -2.75. Plug in the values to your "final" equation of y=(3)^x -3.
So -2.75=(3^-1)-3.
3^-1 is 1/3, 1/3-3 is -8/3 or -2.6667 which is pretty close to -2.75. So we can say the final equation is y=3^x -3.
Hope this helps! It's a lot easier to solve problems like these given either more points which you can use system of equations with, or with a given base or slope.

In Happyville, the ideal family has four children, at least two of which are girls. If you randomly select a Happyville family t

Answer:

0.3125 = 31.25% probability that it is not ideal.

Step-by-step explanation:

For each children, there are only two possible outcomes. Either it is a girl, or they are not. The probability of a child being a girl is independent of any other child. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
