This trinomial is in a special form that can be
factored into the product of two binomials.
So we set up two sets of parenthses.
As the first term, we have the factors of x², x and x.
For the second term, we have the factors of -40 that add to -3.
In this case, these factors are -8 and +5.
So our answer is (x - 8)(x + 5).
In Joey's neighborhood the ratio of families with dogs to families with cats is 5 to 2. There are 15 more families with dogs than families with cats. How many families have cats, and how many families have dogs?
Answer:
10 families have cats
25 families have dogs
Step-by-step explanation:
The difference of ratio units is 5-2 = 3. The difference in pet counts is 15, so we can see that each ratio unit stands for 15/3 = 5 pets. Then ...
dogs : cats = 5 : 2 = (5·5) : (2·5) = 25 : 10
There are 10 families with cats and 25 families with dogs.

The speed of an object can be found by taking the distance it travels and dividing it by the time it takes to travel that distance. An object travels 100 feet in 2.5 seconds. Let the speed, , be measured in feet per second.
Write an equation to represent the relationship between the three quantities (speed, distance, and time).
speed = [tex]\frac{distance}{time}[/tex]
speed = [tex]\frac{100}{2.5}[/tex]
speed = 40 feet per second

f(x) = 3x + 1. Solve for x if f(x) = 19
Answer:
Step-by-step explanation:
f(x) = 3x + 1
First, we substitute 19 for x :
f(x) = 3(19) + 1
Next we re write the problem and solve for 3 times 19 :
f(x) = 57 + 1
So, the answer should be :
f(x) = 58
The equation of line L is y=5x+1
The equation of line L is 2y-10x+3=0
Show that these two lines are parallel.
Please help, will award brainliest.
Answer:
see explanation
Step-by-step explanation:
Parallel lines have equal slopes.
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
L₁ is y = 5x + 1 ← in slope- intercept form
with slope m = 5
L₂ is 2y - 10x + 3 = 0 ( subtract - 10x + 3 from both sides )
2y = 10x - 3 ( divide all terms by 2 )
y = 5x - [tex]\frac{3}{2}[/tex] ← in slope- intercept form
with slope m = 5
Since L₁ and L₂ have equal slopes then they are parallel lines

Anna is x years old and her sister, Jane, is y years younger.
How old was Anna when her sister was born?
========================================================
Explanation:
Let's use numbers in place of the variables
Let's say Anna is 25 years old and her sister Jane is 5 years younger.
This means Anna was 25-5 = 20 years old when Jane was born.
-------------------------
As another example:
Anna = 37 years old
Jane = 10 years younger
Anna was 37-10 = 27 when her sister was born
--------------------------
The examples show that all we do is subtract the x and y values to figure out how old Anna was when her sister was born.
For the first example, we basically did x-y = 25-5 = 20
The second example was x-y = 37-10 = 27
A variable is placeholder for a number. Think of it as a box where a single number will go inside.
Answer:
0+y
Step-by-step explanation:
When Jane was born, Anna was y years old because Jane was 0 years old. That is why the Answer if y or 0+y. But I think the 0+y is more accurate.

Answer:
i dont get what you are trying to say is their a graph u can show
Step-by-step explanation:
Answer:
y = 2x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2, thus
y = 2x + c ← is the partial equation
To find c substitute (3, 5) into the partial equation
5 = 6 + c ⇒ c = 5 - 6 = - 1
y = 2x - 1 ← equation of line

The amount after the transaction.
= Amount in account - Amount withdrawn + Amount deposited
The account balance after the transaction is $160.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example:
2 + 3x + 4y = 7 is an expression.
3 + 4 + 4 - 3 is an expression.
3x + 4 = 5 - 3 is an expression.
We have,
Amount at the account when open = $80
Amount withdrawn = $35
Amount deposited = $115
The amount after the transaction.
= Amount in account - Amount withdrawn + Amount deposited
= 80 - 35 + 115
= $160

Tommy Thomas’s tankard holds 480ml when it is one quarter empty. How much does it hold when it is one quarter full?
Answer:
Tommy Thomas's tankard holds 160ml when it is one-quarter full.
Step-by-step explanation:
When Tommy's tankard holds 480ml when it's one-quarter empty. There are three other quarters in the tankard. So, you would divide 480 by 3 to see how much is in each of the other 3 quarters. The answer comes down to 160ml per quarter, which equals one-quarter full.

HURRY PLZ 20 POINTS AND BRAINLIEST TO FIRST CORRECT ANSWER For dinner, Abelita chooses the Italian salad that costs $3.99 before tax, and Franco chooses the fettuccini alfredo that costs $7.17 before tax. If the sales tax is 5 percent, explain how to find the total cost for their dinner.
Answer: First, add 3.99 + 7.17. Then take the sum of those two numbers and multiply it by .05 to get 0.55. Since we are dealing money, round to the nearest hundredth to get .56. Add the sum of 3.99 and 7.17 (11.16) and .55 to get a total of 11.71. Therefore the total cost of their dinner, including tax, was $11.71.

Samir goes to a farmers market to buy some fruit.
He fills a large bag with 29kg of apples.
He realises that he cannot carry this weight, so puts some of the apples into a smaller bag.
The weight of the apples in the large bag is 15kg larger than the smaller bag.
(a) What is the weight of the smaller bag?
Answer:
Weight of Smaller Bag = 7kg
Weight of Larger Bag = 22kg
Step-by-step explanation:
x = weight of smaller bag
x + (x + 15) = 29
2x + 15 =29
2x = 14
x = 7

what is the equation of the line that is perpendicular to the given line and has an x-intercept of 6?
Answer:
y = 4/3x - 6
Step-by-step explanation:
The slope of the 1st line is -3/4
So for the perpendicular line it has to be the exact opposite.
That looks like this ---> 4/3x
And the y-intercept is -6 because if you make a straight line where the x intercept is it matches.
The equation would look like this
y = 4/3x - 6
