Step-by-step explanation:
Solve for x:
8 x - 13 = 2 x + 17
Hint: | Move terms with x to the left hand side.
Subtract 2 x from both sides:
(8 x - 2 x) - 13 = (2 x - 2 x) + 17
Hint: | Combine like terms in 8 x - 2 x.
8 x - 2 x = 6 x:
6 x - 13 = (2 x - 2 x) + 17
Hint: | Look for the difference of two identical terms.
2 x - 2 x = 0:
6 x - 13 = 17
Hint: | Isolate terms with x to the left hand side.
Add 13 to both sides:
6 x + (13 - 13) = 13 + 17
Hint: | Look for the difference of two identical terms.
13 - 13 = 0:
6 x = 17 + 13
Hint: | Evaluate 17 + 13.
17 + 13 = 30:
6 x = 30
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of 6 x = 30 by 6:
(6 x)/6 = 30/6
Hint: | Any nonzero number divided by itself is one.
6/6 = 1:
x = 30/6
Hint: | Reduce 30/6 to lowest terms. Start by finding the GCD of 30 and 6.
The gcd of 30 and 6 is 6, so 30/6 = (6×5)/(6×1) = 6/6×5 = 5:
Answer: x = 5

a ball is thrown vertically upward from the ground. it's distance in feet from the ground in t seconds is s=-16t+224t. after how many seconds will the ball be 768 feet from the ground? pls help!!!
Answer:
3.692seconds
Step-by-step explanation:
distance s is represented by the following equation s=-16t+224t
given the distance=768ft
replace s by 768 in the equation to find t (time):
768=-16t+224t
768=208t
t=768/208 =48/13 =3.692seconds

Step-by-step explanation:
We have to find the value of the expression ( 4x - 2y ).
Also, given that,
x = 7
y = -3
So, to find the value of the given expression, you have to replace x and y with 7 & -3 respectively.
Let us solve it now.
4x - 2y

(5x+30)=7x ??
Can anyone help me
Answer:
the answer is x=15.....
Answer:
Step-by-step explanation:
(5x+30)=7x Subtract 7x from both sides. 5x+30−7x=0 Combine 5x and −7x to get −2x. −2x+30=0 Subtract 30 from both sides. Anything subtracted from zero gives its negation. −2x=−30 Divide both sides by −2. x= −2 −30 Divide −30 by −2 to get 15. answer should be x=15
solve this system of equations 2x+4y=-48
Answer:
x=-24-2y
y=-12-x/2
Step-by-step explanation:
To solve for x move everything to one side, 2x=-48-4y, then you can divide by 2 to just get x, x=-24-2y.
To solve for y move everything to one side, 4y=-48-2x, then you can divide by 4 to just get y, y=-12-x/2.

the graph of a line gets _____
as the value of the slope gets bigger.
A. steeper
B. longer
C. less steep
D. shorter
Answer: Less Steep
Step-by-step explanation: the graph of a line gets less steep as the value of the slope gets bigger.
The graph of the line gets steeper as the value of the slope gets bigger. Then the correct option is A.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
If the value of the slope is bigger then the line will be steeper.
Thus, the correct option is A.

What is the area of a triangle?The area of a triangle of base b and height h is given by:
A = 0.5bh.
Item a:
We have that b = 40, h = 35, hence the area in miles squared is given by:
A = 0.5 x 40 x 35 = 700.
The density is the number of animals divided by the area, hence:
D = 42500/700 = 60.7.
Item b:
We have that b = 38, h = 25, hence the area in miles squared is given by:
A = 0.5 x 38 x 50 = 950.
Then, the density is:
D = 60800/950 = 64.
Item c:
We have that b = 42, h = 49, hence the area in miles squared is given by:
A = 0.5 x 42 x 49 = 1029.
Then, the density is:
D = 57300/1029 = 55.7.
Hence option C is correct.

NO LINKS!! Explain your answer (show the support by showing the changes in x and y on your table). If the relationship is linear, inverse, or exponential, write the equation.
#7 and #8
Answer:
7. inverse relationship; equation: y = 16/x
8. no relationship; no equation
Step-by-step explanation:
The attachment shows the support for the conclusions. The relationship can be chosen from those offered by looking at differences, ratios, or products of y-values for sequential x-values.
linear: constant differencesexponential: constant ratiosinverse: constant products__
7.In the first problem, we note that the relationship between y-values varies inversely as the relationship between x-values: when x goes up by a factor of (n+1)/n, the value of y goes down by its inverse factor: n/(n+1). That same relationship is observed by noting that the product of x and y is a constant, 16.
relationship: inverse
y = 16/x
__
8.As we looked at the table, we thought this might be an exponential function. Each y-value seemed to be twice the one before—until we got to x=5. As x went from 4 to 5, the y-value increased by a factor of 16, not 2. This means there is no simple relationship between x and y, and no simple equation that will describe the sequence of y-values.
Answer:
Linear relationship: increasing or decreasing one variable will cause a corresponding increase or decrease in the other variable.
Inverse relationship: the value of one variable decreases as the value of the other variable increases.
Exponential relationship: a constant change in the independent variable (x) gives the same proportional change in the dependent variable (y)
Question 7
As the x-value increases (by one unit), the y-value decreases.
Therefore, this is an inverse relationship.
The y-values are calculated by dividing 16 by the x-value.
[tex]\sf y=\dfrac{16}{x}[/tex]
Question 8
As the x-value increases, the y-value increases.
The y-value increases by a factor of 2 for each x-value increase of 1 unit from 1 ≤ x ≤ 4 and 5 ≤ x ≤ 6.
[tex]\sf y=2^x \ for \ 1\leq x\leq 4[/tex]
[tex]\sf y=2^{(x+3)} \ for \ 5\leq x \leq 6[/tex]
These are separate exponential relations for restricted domains.
So there doesn't appear to be one relationship for a non-restricted domain.

17 divided into 3,536
Answer: 208
Step-by-step explanation:
The number 3536 is called the numerator or dividend, and the number 17 is called the denominator or divisor.
The quotient of 3536 and 17, the ratio of 3536 and 17, as well as the fraction of 3536 and 17 all mean (almost) the same:
3536 divided by 17, often written as 3536/17 = 208

2. Bart sold 5 more than 3 times as many refrigerators last month than the number of
refrigerators sold by Bill. If together they sold 125 refrigerators last month, how many did
each person sell?
Answer:
Bart 95 bill 30
Step-by-step explanation:
Bill=b
Bart = (3b+5)
b+ (3b+5) = 125
4b=120
b=30 Bill sold 30 refrigerators
3(30)+5 = 95 (Bart sold 95 refrigerators)
95+30=125
