y = -x + 2 identify the slope and y intercept and graph
Answer:
The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.
Answer:A rule for a function can be written by analyzing a graph. Using slope-intercept form, standard form, and point-slope form, functions can be written from a given graph.
To write a function in slope-intercept form given a graph, determine the slope and y-intercept of the graph and then substitute these values into the formula y = mx + b. If it is not possible to determine the y-intercept from the graph, determine a different point, substitute it into the equation and solve for b.
Example Find the function rule for the graph using the slope-intercept form.Step 1. Choose any two points to find slope. (-3, 1) & (3, -3) Find the value of the y-intercept.Step 3. Substitute the m and b values into y = mx + b to create the function rule.

The dividend is 5 1/6
The divisor is 5 1/6
The dividend is second number in this equation.
The quotient is correct.
Step-by-step explanation:
the dividend divided by the divisor equals the quotient
The dividend is [tex]5\frac{1}{6}[/tex] and the divisor is [tex]2\frac{5}{12}[/tex] and the quotient is [tex]2\frac{4}{29}[/tex]. Therefore, option A is the correct answer.
The given equation is [tex]5\frac{1}{6}\div2\frac{5}{12} =2\frac{4}{29}[/tex].
What is the division?The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.
Here,
[tex]5\frac{1}{6}\div2\frac{5}{12} =2\frac{4}{29}[/tex]
⇒ 31/6 ÷ 29/12 = 62/29
⇒ 31/6 × 12/29 = 62/29
⇒ 62/29 = 62/29
Here, the dividend = [tex]5\frac{1}{6}[/tex] and the divisor = [tex]2\frac{5}{12}[/tex] and the quotient = [tex]2\frac{4}{29}[/tex]
Therefore, option A is the correct answer.

I need the value of X
Answer:
x=18
Step-by-step explanation:
6x-3 and 75 are not equal to each other. If you look closer you can see that 75 is an acute angle making it less than 90 degrees and 6x-3 is an obtuse angle meaning it is bigger than 90 degrees. Therefore you add both 75 and 6x-3 to get 180 because 180 is equal to a straight line and an acute angle and an obtuse angle both form a straight angle when together. So your problem would be 75+(6x-3)=180

Be positive or negative? Explain why or why not.
This is a personal question!
Answer:
It would be positive
Step-by-step explanation:
To do anything with fractions you need to find a common denominator, in this case lets say its 128. the 9 in the negative side would need to be multiplied by 8 like it's denominator making it 72. You would do the same to the other fraction giving you the fractions -72/128 and 144/128 from here you add to get 72/128 which is positive
Answer:
positive
Step-by-step explanation:
-9/16= -0.5625
9/8= 1.125
-9/16+9/8= -0.5625 + 1.125(in the addition of opposite signs u should figure out the largest num and should substract the other numa nd assign the sign of the biggest nym)
=0.5625

A rectangular enclosure at the zoo is 35 feet long by 18 feet wide. The zoo wants to double the area of the enclosure by adding the same distance x to the length and width. Write and solve an equation to find the value of x. What are the dimensions of the enclosure?
Answer:
the value of x is 10
Step-by-step explanation:
The new length is 35+10=45 and the new width is 18+10=28.
What is Area of Rectangle?Area of rectangle is length times of breadth.
Given that enclosure at the zoo is 35 feet long by 18 feet wide. It means length is 35 feet and width is 18 feet.
Area of Rectangle=Length × Width
=35×18
=630
The zoo wants to double the area of the enclosure by adding the same distance x to the length and width.
(35+x)×(18+x)=1260
630+35x+18x+x2=1260
x2+53x+630-1260=0
x2+53x-630
Now use the quadratic formula we get
x=10.
The new length is 35+10=45
The new width is 18+10=28.
Hence the new length is 35+10=45 and the new width is 18+10=28.

Johnna has $440 in her savings account the first week. She deposits $65 in her account every week. How much money will Johnna have in her savings account in the 25th week?
she will have $2065 in her savings account after the 25th week.
Answer:
2,065
Step-by-step explanation:
First you need to figure out 65 times 25 because she puts $65 into her account every week so you need to multiply by 25 because you have to figure out how much money she will have on the 25th week so:
$65 * 25 = 1,625
then you need to add that to 440 because ahe still only has 440 in her account until now so, in conclusion, she has 2,065 because:
$65 * 25 = $1,625 + $440 = 2,065

A computer store buys a computer system at a cost of $572.40. The selling price was first at $954, but then the store advertised a 20% markdown on the system. Answer parts a and b.
Answer:
The sale price is $763.20
The price for club members is $610.56
The current selling price is $763.20, and the cost to members with an additional 10% reduced rate is $686.88.
What is a percentage?A percentage is a ratio or number that may be expressed as a fraction of one hundred. And the sign for it is "%."
Given, a computer store buys a computer system at a cost of $572.40.
And the selling price was first at $954, but then the store advertised a 20% markdown on the system.
To find the current sale price:
Current sales price;
use percentage formula,
= $954 - (20% × $954)
= $954 - (0.2 × $954)
= $954 - $190.80
= $763.20
To find the cost to club members at 10% additional reduced price:
use percentage formula,
= $763.20 - (10% × $763.20)
= $763.20 - (0.1 × $763.20)
= $763.20 - $76.32
= $686.88
Therefore, the current sale price is $763.20, and it will cost $686.88 to the members.
