write the equation of the line that passes through points (-7,8) and (4,-5)
Answer:
y=-3/11x+67/11
Step-by-step explanation:
y-8=-5-8/4--7(x--7)
y-8=-3/11(x+7)
11y-88=-3x-21
11y=-3x-21+88
11y=-3x+67
y=-3/11x+67/11
Answer:
y = -13/11x - 3/11
Step-by-step explanation:
First, find the slope of the line using the slope formula.
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{-5-8}{4-(-7)}\\m=-\frac{13}{11}[/tex]
Then, use the point-slope formula and substitute the values for the variables.
[tex]y-y_1=m(x-x_1)\\y-8=-\frac{13}{11}(x-(-7))\\y-8=-\frac{13}{11}x-\frac{91}{11}\\y=-\frac{13}{11}x-\frac{3}{11}[/tex]
On the planet Tott, there are 9 frenks to every 8 vreels. If farmer Yoy
has 80 frenks on her rew farm, how many vreels are on the farm?
Round to the nearest tenth if rounding is needed?
Answer:
71.1 vreels on the farm
Step-by-step explanation:
Create a proportion where x is how many vreels are on the farm:
[tex]\frac{9}{8}[/tex] = [tex]\frac{80}{x}[/tex]
Cross multiply and solve for x:
9x = 640
x = 71.1
So, to the nearest tenth, there are 71.1 vreels on the farm.
Find the measure of e . A. 88 B. 46 C. 44 D. 90
Answer:
The answer is A. 88.
Step-by-step explanation:
To solve for the measure of angle ( [tex]e[/tex] ), start by noticing that 92 degrees and ( [tex]e[/tex] ) sum up to 180 degrees, which makes them supplementary angles.
Two angles are said to be supplementary angles if they add up to 180 degrees. Supplementary angles form a straight angle (180 degrees) when they are put together. In other words, angle 1 and angle 2 are supplementary, if Angle 1 + Angle 2 = 180 degrees.
Since angle 92 degrees and angle ( [tex]e[/tex] ) sum up to 180 degrees, the equation will look like [tex]92[/tex]°[tex]+e=180[/tex]°. To solve the equation, start by subtracting 92 degrees from both sides, and the equation will look like [tex]e=88[/tex]°. The final answer will be that the measure of angle ( [tex]e[/tex] ) is 88 degrees.

56-x=728+2x what's the answer?
Answer:
56-x=728+2x
1.) rearrange
[tex]56x = 728 + 2x \\ \ - x + 56 = 728 + 2x[/tex]
[tex] - x + 56 = 728 + 2 x \\ \\ - x + 56 = 2x + 728[/tex]
2.)subtract 56 on both side
[tex] - x + 56 = 2x + 728 \\ \ - x + 56 - 56 = 2x + 728 - 56[/tex]
3.) simplify
[tex] - x = 2x + 672[/tex]
4.)Subtract 2 on both sides
[tex] - x = 2x + 672 \\ \\ - x - 2x = 2x + 672 - 2x[/tex]
5.) simplify
[tex] - x - 2x = 2x + 672 - 2x \\ \\ - 3x = 2x + 672 - 2x \\ \\ - 3x = 672[/tex]
6.)divide both sides on the same equation
[tex] - 3x = 672 \\ \\ \frac{ - 3x}{ - 3} = \frac{672}{ - 3} [/tex]
7.) simplify
[tex]x = - 224[/tex]
8.) answer
[tex]x = - 224[/tex]

What comes next in this sequence? - [ 1, 45, 104, 1034 ] - Please state the pattern and why you chose that answer.
A. 34556
B. 4567
C. 401
D. 54
Answer:
The answer is A. 34556
Step-by-step explanation:
The 5th term of the sequence would be a{5} = 10334.
What is a mathematical function, equation and expression?Sequence : A sequence is defined as an arrangement of numbers in a particular order.
Function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function
Expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators
Equation : A mathematical equation is used to equate two expressions.
Given is the sequence -
1, 45, 104, 1034
We can write the next term as -
a{n} = 10a{n - 1} - 6
So, we can write -
a{5} = 10 x 1034 - 6
a{5} = 10340 - 6
a{5} = 10334
Therefore, the 5th term of the sequence would be a{5} = 10334.

Find the area of each rectangle first
and then add the two areas together.
Answer:
44m²
Step-by-step explanation:
Area of larger rectangle
= length × breadth
= 8m × 4m
= 32m²
Area of smaller rectangle
= length × breadth
= 4m × 3m
= 12m²
Total area of the figure
= Area of larger rectangle + Area of smaller rectangle
= 32m² + 12m²
= 44m²

Cam went to the beach and collected seashells. when he put them into 2 piles, 3 piles, and then 5 equal piles. he didn't have any extra. when he put them into 4 piles, he had exactly 2 extra. how many seashells could cam have collected?
Hey there! I'm happy to help!
We see that the number of seashells is divisible by 5, 3, and 2, but not 4. One thing I like to do to find this number is to multiply together all of the numbers it is divisible by. This product will be divisible by all of the numbers because you multiplied them all together! Let's do this below.
2×3×5=30
We see that our answer is 30, and it is divisible by 2, 3, and 5. 30 also isn't divisible by four. If you tried to do so, you would get 28 (4×7) with a remainder of two.
Therefore, Cam could have collected 30 shells.
Have a wonderful day! :D

The Bayesian Theorem is a theorem that centers or basis its claim on the facts that the probability of an event occurring is based on Prior Knowledge that of situation or Prior factors of the Event
i'll explain further with an example
Given that when two unfair dice are thrown a 100 times the probability of getting the higher figure in the range of 6-8 , Therefore the Bayesian Theorem simply assumes that this range of 6-8 to be the highest for all 100 throws of two dice.
The Bayesian model is given as
[tex]B=Prior * Likelihood=Posterior * Marginal[/tex]
Bayesian model is a statistical model.
This leads us to the definition of the Likelihood function

solve |5-9|+2·3= help porfavor !! asap pls
Answer:
10
Step-by-step explanation:
|5-9|+2*3
lets use the P.E.M.D.A.S order of operations rule
we have no parenthesis or exponents, so we skip to multiplication
2*3=6
then we do addition/subtraction
since the subtraction sign comes first in the equation, we evaluate
5-9=-4
since the subtraction part is in the absolution value signs, we change -4 to its absolute value.
|-4|=4
now we are left with 4+6
add
4+6=10
so, |5-9|+2*3=10
