Answer:
y=-3x+2
Step-by-step explanation:
as x goes up on y goes down 3
slope is change in y over change in x
-3/1=-3
the y intercept is (0,2) so the y intercept is +2
what is the rule for solving any equation?
A. just look at it and it will be solved
B. always add the numbers
C. Do the inverse or opposite operations
D. the is no rule for solving equations
Answer:
C) Do the inverse or opposite operations
Step-by-step explanation:
Take for example the equation 4=2x. Because 2 is being multiplied by x, the only way for x to get by itself is to do the opposite operation; dividing both sides by 2 to get 2=x.
can someone plz help me
Answer:
x is less than or equal to negative 14.
Step-by-step explanation:
so for now we should pretend that the greater than or equal to is an equal sign, and simplify the problem to get x alone on a side
remove 5 from each side
-x/3=1/3-5
-x/3=14/3
multiply both sides by 3
-x=14
x=-14
so we can now replace the equal sign with the equal or greater to, so x is less than or equal to -14

Answer:
Sum is the addition -8x^2+3-9x^2+3x-3 Combine like terms -17x^2+3xA tree grows 2 inches per year. It was 14 inches tall when it was planted. what would be this function discrete continuous or neither? whould it be a linear an exponential or neither? what would be the domain?
please help greatly appreciated
Answer:
This function is a continuous linear function that's domain is all positive real numbers.
Step-by-step explanation:
This function is continuous because every linear function is continuous and this function is the linear function y = 2x+14 where x is the years it has been planted and y is the height.
It is a linear function, it's hard to explain, but it has a dependent variable, the height of the tree that changes at a constant rate with the independent variable which is time in years.
The domain is all positive real numbers since time/years can not be negative.
Alaina needs to sell 225 boxes in order to be the top seller. She sells thin mints and samoas to all of her customers for a total of $628.00 in sales. The thin mints sell for $3.00 each and the samoas sell for $2.50 each. Which system of equations below could be used to find how many boxes of thin mints and samoas were sold?
Answer:
94 boxes of samoas
131 boxes of thin mints
Step-by-step explanation:
m=mints
s=samoas
s+m=225 m=225-s
s(2.5)+m(3)=628
2.5s+3m=628
substitute for m
2.5s+3(225-s)=628
2.5s+675-3s=628
reduce
-0.5s=-47
s=94
m=131

In a survey of U.S. Adults, 16% say they have had someone take over their email accounts without their permission. You randomly select 250 U.S. Adults and asked them whether they have had someone take over their email accounts without their permission. Find the probability that the number of U.S. Adults who say they have had someone take over their email accounts without their permission is : a. At most 40 b. Less than 45 c. Exactly 48
Answer:
a. At most 40
Step-by-step explanation:
If we take the survey that was done as a basis then we would use the 16% that was obtained as the number of overall US adults that have had their accounts used without their permission. Assuming that the 250 selected individuals were selected at random and without bias then those 250 would also be representative of the entire population. Therefore, we would simply need to multiply the number of selected individuals by the percentage in decimal form.
16 / 100 = 0.16
250 * 0.16 = 40
Finally, we can see that roughly 40 individuals would have had their email used without permission.

describe and correct the error in solving the proportion?
Answer: Choice B
They did not perform the cross multiplication properly
The correct step should be m*24 = 8*15 which solves to m = 5
========================================================
Explanation:
In general, if we had the equation A/B = C/D, then it cross multiplies to A*D = B*C. We refer to this as cross multiplication because of the shape made when we connect the terms (to figure out what multiplies with what). The diagram below shows what I mean.
So that's why m/8 = 15/24 cross multiplies to m*24 = 8*15
Simplifying things a bit leads to 24m = 120. Then we divide both sides by 24 to fully isolate m and we get m = 120/24 = 5. Therefore, m = 5.
You have a sack of 90 balls. 35 blue, 30 green and 25 pink. If you randomly pull one ball out of the bag, what is the probability of pulling a green ball?
Answer:
P(Green ball) = 1/3
Step-by-step explanation:
You have a sack of 90 balls. 35 blue, 30 green and 25 pink. If you randomly pull one ball out of the bag, what is the probability of pulling a green ball?
The Probability of pulling a green ball =
P(Green ball) =
Number of green balls/ Total number of balls
= 30 green balls/90 balls
P(Green ball) = 1/3

A large field measures 70 feet by 525 feet. If you divide it up into equal square garden plots, what size would the largest possible plot be with sides of whole number length?
9514 1404 393
Answer:
35 feet square
Step-by-step explanation:
The greatest common factor of 70 and 525 is 35. The largest square plot can be 35 feet on a side.
70 = 2·35
525 = 15·35

I like to find the GCD (greatest common divisor) using Euclid's algorithm. We find the remainder when dividing the larger by the smaller. When that remainder is not zero, we replace the larger number with the remainder, and repeat. When the remainder is zero, the divisor is the GCD.
525/70 = 7 r 35
70/35 = 2 r 0 . . . . . 35 is the GCD
a ladder is leaning against a building. the top of the ladder is 21 feet up the wall. the bottom of the ladder is 20 feet away from the base of the building. how long is the ladder
Answer:
29
Step-by-step explanation:
We can use the pythagorean theorem to find the length of the ladder
[tex] {20}^{2} + {21}^{2} = c {}^{2} [/tex]
[tex]400 + 441 = {c}^{2} [/tex]
[tex]841 = {c}^{2} [/tex]
[tex]c = 29[/tex]
The answer is 29

Answer:
z is 95 degrees.
Step-by-step explanation:
Linear angle pairs make 180 degrees. Since ∠ABC is a straight line, it is 180 degrees. And since ∠ABD and ∠DBC are on that line, they are a linear angle pair. You just need to find out what number + 85 degrees would = 180 degrees, which in this case, is 95.

. Which of the following is a zero of the polynomial f(x)= x5+2x4+x+2?
A. I
B.-1
C.-2
D. 2
Answer:
x = -2 is a function
Step-by-step explanation:
To get which is a zero, we have to look at one value of x which when substituted into the polynomial will give -1
we have this as:
Let us try the value x = -2
-2^5 + 2(-2)^4 - 2 + 2
= -32 + 32 - 2 + 2 = 0
This means that the term x = -2 is a root of the equation

Answer:
C is the answer.
find the value of the variables. x and y
Answer:
x = 29.4
y = 17
Step-by-step explanation:
sin 90° / 34 = sin 60° / x
x = 34·sin 60°
x = 29.4
sin 90° / 34 = sin 30° / y
y = 34·sin 30°
y = 17
