Answer:
y=2x+7
Step-by-step explanation:
find (-5,-3)
use the slope to find the y intercept
intercept is (0,7)
use formula y=mx+b to plug in numbers
(slope is m and y intercept is b)
y=mx+b
y=2x+7

Step-by-step explanation:
[tex]\angle{1} = 77°[/tex] because they are vertical angles.
The 77°-angle is supplementary with [tex]\angle{2}[/tex] therefore
[tex]77° + \angle{2} = 180° \Rightarrow \angle{2} =180° -77° = 103°[/tex]
[tex]\angle{3}[/tex] and [tex]\angle{2}[/tex] are vertical angles so
[tex]\angle{3} = \angle{2} = 103°[/tex]
Answer:
103 = angle 3
103 = angle 2
angle 1 = 77
Step-by-step explanation:
angle 1 = 77
angle 2 = angle 3
360 - 77x2 = 206
206/2 = 103
Recently, a nurse commented that when a patient calls the medical advice line claiming to have the flu, the chance that he or she truly has the flu (and not just a nasty cold) is only about 4%. Of the next 25 patients calling in claiming to have the flu, we are interested in how many actually have the flu.
Find the probability that at least four of the 25 patients actually have the flu.
The probability that at least four of the 25 patients actually have the flu is 0.013
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
The probability P(X ≥ 4).
By De Morgan's Law, this is equal to 1-P(X<4).
If we add up the values of x=0,1,2,3 from our pmf,
[tex]$p_x = \binom{25}{x}(0.04)^x(1-0.04)^{25-x}$[/tex]
So, x=4
P(4) = 25! / 4! ( 25- 4)! x [tex]0.04^4[/tex] [tex](1 - 0.04)^{25- 4}[/tex]
P(4) = 0.013
Hence, the probability that at least four of the 25 patients actually have the flu is 0.013

Explain why solving a system of equations using graphing is not a useful solution technique?
Answer:
solving a system of equations using graphing is not a useful solution technique because you are plotting on a 2D surface. For example, if you graph the system below, you get the following graph. ... While you can approximate the solution to this system, you cannot say exactly where the intersection point is since it does not fall on integer values on the number lines.

Answer:
1/9
Step-by-step explanation:
When it has a bar over it, that means that the one continues. So the actual decimal is 0.11111111111. To find the answer, divide all the rational numbers. I'll do A for example. A. 1/11 (1 divided by 11) which is .09090909. It's close, but not the answer. Now, try the others.
The actual decimal is impossible to write out as it is infinite, so it is represented with a bar on top of the repeating value. \[0.03\]|

Given f (x) = x2 + 6x + 5 and g(x) = x3 + x2 − 4x − 4, find the domain of f over g of x period
{x ∈ ℝ}
{x ∈ ℝ| x ≠ −5}
{x ∈ ℝ| x ≠ −1, −2, 2}
{x ∈ ℝ| x ≠ −2, 2}
The main limiting issue with the domain this function is potentially picking an x-value that makes that denominator equal 0, because dividing by 0 is bad.
So, the domain will be all real numbers, except for those that make g(x)=0.
g(-1) = 0, g(-2)=0, and g(2) = 0, so -1, -2, and 2 must be excluded from the domain.
Your answer is {x ∈ ℝ| x ≠ −1, −2, 2}.
Answer:
[tex]\textsf{Domain}: \quad \{ x \in \mathbb{R}\;|\;x \neq -1, -2, 2\}[/tex]
Step-by-step explanation:
Given functions:
[tex]\begin{cases} f(x)=x^2+6x+5\\g(x)=x^3+x^2-4x-4\end{cases}[/tex]
Factor function f(x):
[tex]\begin{aligned}\implies f(x)&= x^2+6x+5\\&=x^2+x+5x+5\\&=x(x+1)+5(x+1)\\&=(x+5)(x+1)\end{aligned}[/tex]
Factor function g(x):
[tex]\begin{aligned}\implies g(x)&=x^3+x^2-4x-4\\&=(x+1)(x^2-4)\\&=(x+1)(x+2)(x-2)\end{aligned}[/tex]
Therefore the composite function is:
[tex]\implies \dfrac{f(x)}{g(x)}=\dfrac{(x+5)(x+1)}{(x+1)(x+2)(x-2)}[/tex]
A rational function is undefined when the denominator equals zero.
Therefore, the given composite function is undefined when (x+1)(x+2)(x-2)=0:
[tex]x+1=0 \implies x=-1[/tex][tex]x+2=0 \implies x=-2[/tex][tex]x-2=0 \implies x=2[/tex]The domain of a function is the set of all possible input values (x-values).
Therefore, as the composite function is undefined when x = -1, x = -2 and x = 2, the domain is:
[tex]\{ x \in \mathbb{R}\;|\;x \neq -1, -2, 2\}[/tex]Which list shows the contestants in order by their completion times from fastest to slowest?

What is the midpoint of AB?
Answer:
[tex](-4, -\frac{1}{2})[/tex]
Step-by-step explanation:
Hi there!
We are given the line segment, with the end points AB
The coordinates of A are (-5, -4), and the coordinates of B are (-3, 3).
We want to find the midpoint of the line segment AB
The midpoint formula is given as [tex](\frac{x_1+ x_2}{2}, \frac{y_1 + y_2}{2})[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are coordinates
We have two coordinates, which is what we need, but let's label their values to avoid any confusion:
[tex]x_1=-5\\y_1=-4\\x_2=-3\\y_2=3[/tex]
Now substitute those values into the formula:
[tex](\frac{x_1+ x_2}{2}, \frac{y_1 + y_2}{2})[/tex]
[tex](\frac{-5+ -3}{2}, \frac{-4+ 3}{2})[/tex]
Now simplify the numerator and denominator
[tex](\frac{-8}{2}, \frac{-1}{2})[/tex]
Simplify again:
The midpoint is (-4, [tex]-\frac{1}{2}[/tex])
Hope this helps!

The graph of y=f(x) is shown below. find all the values of x where f(x)=6
Answer:
x = -4, 4
Step-by-step explanation:
When it says find all the values of x where f(x) = 6, it is basically asking for the x values where y would equal 6. So if you look at the graph, y equals 6 when x = -4 and x = 4.

You buy vegan shredded cheese in 5 lb bags. Your recipe for burritos requires 3 ounces of vegan cheese per serving. How many servings can you make per 5 lb bag?
The 26.66 servings you can, make per 5 lb bag if recipe for burritos requires 3 ounces of vegan cheese per serving.
What is unit conversion?It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, multiplication by a conversion factor.
We have:
You buy vegan shredded cheese in 5 lb bags.
1 lb = 16 ounces
5 lb = 80 ounces
Recipe for burritos requires 3 ounces of vegan cheese per serving.
1 → 3
x → 80
x is the number of serving
x = 80/3 = 26.66
Thus, the 26.66 servings you can, make per 5 lb bag if recipe for burritos requires 3 ounces of vegan cheese per serving.
