# Algebra exam tomorrow??

Topic: Practice writing algebraic expressions
June 17, 2019 / By Candice
Question: Okay so I am 13 in 7th grade. Tomorrow I take a 2 hour test to determine whether i can get into 9th grade algebra in 8th grade. The exam is a fraction/decimal compency and an algebra readiness test. What is on algebra readiness tests. Any good tips for tomorrow??? Help would be Gregor appreciated. What should I need to know for tomorrow???? Thanks I am pretty good at math.

Things you should know: BE confident with pre-Algebra skills know order of operations adding, subtracting, diving, multiplying, decimals and fractions reducing equations comparing inequalities solving equations and inequalities identify properties( associative, commutative, identity of addition and multiplication) find least common multiple find product find quotient write decimal as percent SIMPLIFICATION Here are some examples an algebra readiness test would have 1) Simplify 3 - 15 × 5 (x^3)^5 (7/24) - (15/90) Evaluate dp/ (d + p) for d = 9 and p = 2 To print tickets, a printer charges a \$70 setup fee plus \$1.25 per ticket. Write an algebraic expression for the cost of t tickets. What is the cost of 650 tickets? Justin wants to use 188 ft of fencing to fence off the greatest possible rectangular area for a garden. What dimensions should he use? What will be the area of the garden? Simplify expression 1 – 7(–3x + 2) Use the Distributive Property to multiply. 5(3m + 5) SOlve equation 6b = 18 w/3 = 18 –6 + 2x = –10 Solve the inequality. y /-6 > 10 Compare Fractions 2/3 ___ .2 These are just some examples.

1. You have change the form 3x - 5y = 10 into y = mx + b (m is your slope and b is your y-intercept is b). So, now all you have to do is play around with this equation given 3x = 10 + 5y 5y = 3x - 10 y = (10/5) + (3/5)x y = (3/5)x + 2 Now, m = (3/5) and b = 2 ....... There you go!! I think the mistake you are making is that you are not dividing both terms by 5 when it goes to the other side. 2. y-intercept = b = 5 Now, come up with an equation y = mx + b y = mx + 5 You know that when y = 0, x = 3, right? (x-intercept) 0 = m(-3) + 5 -3m = -5 m = 5/3 Your equations is then y = (5/3)x + 5 3. Regarding flipping signs, I found this example online. This might help you Question: I have a question about an inequality problem. Here it is: Solve and graph 5 - 3x => 17. (=> is greater than or equal). Please tell me why you flip the inequality sign when divinding by a negative number. Thanks. Sean Hi Sean, It has to do with the way we order the numbers. 20 is greater than 5, but -20 is less than -5. (20 degrees is warmer than 5 degrees but -20 degrees is colder than -5 degrees.) Using the inequality symbol 20 > 5 but -20 < -5 In the inequality above, when you multiply "20 > 5" on both sides by -1 (or divide by -1), the inequality changes direction. I hope this helps,
Rearranging 3x-5y=10: 5y=3x-10 y=(3/5)x -2 Standard form: y= mx+C where m is the gradient of the line and C is the y-intercept. So from the above rearrangement: y= (3/5)x -2, m=(3/5) which is the gradient of the line ie. slope of the line can? next. Standard eqn of a straight line: y= mx+c, where m is the gradient of the line and C is the y-intercept. So from the question, it is given that y-intercept is 5 therefore C=5. To get the gradient of a slope, it is always the value of Y divided by the value of x, therefore m, which is the gradient of the line, will be (5/3) So right now, substituting the values you have into the standard eqn, you have: y=(3/5)x + 5! (: When working with inequalities, you flip the sign when you are adding or removing negative signs Example: -4< 5 will be changed to 4> -5 Also flip the sign when you multiply both sides by exponential log Example: 4<5 will be changed to ln4> ln 5 Reason can be deduce when you plot Y= ln X (: I dont know why im doing this when i have a paper in 12 hours' time >< but cool, good luck with math!
