Factor 2x2 - 9x - 5 using substitution.
Answer:
(2x+1)(x−5)
Step-by-step explanation:
If we factor 2x² - 9x - 5 using substitution, we would have; (2x+1)(x−5).
How to factor the expressionThe substitution method of factorization requires that we replace it with another variable. Thus, in the expression above, we would first determine the product of the leading coefficient, and find two numbers that add up to the coefficient of the leading term.
The last step is to group the terms and factor the greatest common factor. The result of this factorization would be:
(2x+1)(x−5)

can someone plz answer my question :(
Answer:
When they ask for the rows, that means we need to divide everything by the column totals, not the row totals. (See how there's a total row and a total column? We use the total column.) This seems counterintuitive: just think of it as horizontal.
Let's try the "get to work before 9 am" row.
8/11 = .73
3/11 = .27
11/11 = 1.00
It works! Choice A is correct.
Let's now try the "get to work after 9 am" row.
5/9 = .56
4/9 = .44
9/9 = 1.00
It works too! So if you're allowed to put two answers, choices A and B would both be correct.

You are going to a baseball game and you love to eat salted peanuts while watching the game. You know that you can buy peanuts there, but you know its cheaper to bring your own. When you go to the grocery store to buy some, you see two choices: $3.59 for a 20 oz bag of salted peanuts or $2.59 per pound for loose salted peanuts.
Answer:
I am assuming you are asking which is the cheaper option per ounce since you did not specify a question.
Option 1: 3.59$ for a 20 oz bag
3.59/20=.1795 $/oz
Option 2: 2.59 per 1 pound
1 pound = 16 oz
2.59/16= .161875 $/ozo
Since .16 dollars is less than .18 dollars, the second option, where 1 pound costs $2.59, is cheaper.

Answer:
[tex]m\angle 4 = 117\textdegree[/tex]
Step-by-step explanation:
-Both [tex]\angle 1[/tex]and [tex]\angle 4[/tex] are supplementary, which they both equal to [tex]180\textdegree[/tex]. So, to get the measurement of [tex]\angle 4[/tex], you need to subtract measure of [tex]\angle 1[/tex], from [tex]180\textdegree[/tex] :
-Both [tex]\angle 1[/tex] and [tex]\angle 4[/tex] are supplementary:
[tex]\angle 1 + \angle 4 = 180\textdegree[/tex]
-Find the [tex]m \angle 4[/tex] by subtracting the [tex]m \angle 1[/tex] from [tex]180[/tex] :
[tex]180\textdegree - 63\textdegree = 117\textdegree[/tex]
So, the [tex]m\angle 4[/tex] is [tex]117\textdegree[/tex] .
can somebody explain what the problem is explaining to me
Answer:
The problem basically is saying that find two numbers that add up to 8, where one is three times the other.
Step-by-step explanation:
The best thing to do here is to write a simple system of equations.
b+y=8
b=3y
The first equation means that the total blue paint plus the total yellow paint is equal to 8 ounces.
The second equation means that the blue paint is equal to 3 times the yellow paint.
We can isolate b in the first equation to get b=-y+8
-y+8=3y
8=4y
y=2.
So we have that she needs two ounces of yellow paint.
Therefore she needs six ounces of blue paint.
Drag the yellow bar to 2, and the blue bar to 6.
Hope this helps!
Find the coordinates of the vertices of the figure formed by each system of inequalities. x + y < 9 x - 2y < 12 y < 2x + 3 a. (0, 0), (0, 1), (2, 0) c. (9, 1), (2, 3), (5, 6) b. (10, -1), (-6, -9), (2, 7) d. (0, -1), (2, -1), (3, 6)
Answer:
b. (10, -1), (-6, -9), (2, 7)
Step-by-step explanation:
One way to solve this problem is by graphing (see attachment). In fact, that actually is the easiest way to do this.
First, graph x + y < 9 (red part on the attachment). To do this, isolate the y so that it's like a regular linear equation: y < -x + 9. Graph the line y = -x + 9 first, and then choose a point either on the left or right of the line to plug in for x and y.
Let's just choose (0, 0), which is on the left of the line: 0 < -0 + 9 ⇒ 0 < 9. Since this is a true statement, we know that we should shade the left side of the equation, and not the right side.
Now, graph x - 2y < 12 (blue part on the attachment). It's the same process here as the first inequality. For this one, we find that we also shade to the "left" of the line (it's more "up" than "left", but you get the idea).
Finally, graph y < 2x + 3 (green part on the attachment). Again, it's the same process. For this, we shade to the right.
Now look at the three points that they intersect at: they are (2, 7), (-6, -9), and (10, -1). The answer is thus B.
Step-by-step explanation:
Step 1: Graph each of the inequalities
x + y < 9
x - 2y < 12
y < 2x + 3
It comes out that the vertices are (2, 7), (10, -1), and (-6, -9)
Answer: Option B

A line passes through the points R(–9, 4) and F(1, 2). Two points that lie on a line perpendicular to this line are
Select one:
a.
(–10,–4) and (–5,5)
b.
(10,4) and (5,5)
c.
(15,2) and (24,4)
d.
(2,15) and (4,25)
Answer:
D
Step-by-step explanation:
What you need to do is find the slope of both lines. Perpendicular lines are the negative inverse of each other. The slope of the lie between points R and F is (2-4)/(1+9)=-1/5. Now you need to find the line where the slop is 5. If you look at D, the slope of the line those points lie on is (25-15)/(4-2)=5 which makes D the answer.
Answer:
D. (2,15) and (4,25)
Step-by-step explanation:
The slope of the line that passes through (-9,4) and (1,2) is -1/5 so in order to find the slope that is perpendicular to it, you need to find out with of these pairs of points has a slope that is the negative reciprocal of -1/5 which is 5. So the only points that have the slope of 5 are (2,15) and (4,25).

What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
We have to find the surface area of a sphere with a radius of 11 units
The formula for finding surface area of sphere is 4πr²
where r is the radius of sphere
r=11 units
Surface area =4π.11²
=4×121π
=484 π square units
Hence, 484 π square units t is the surface area of a sphere with a radius of 11 units

Veronica has received a $3,000 gift and is looking for a bank to start a savings account. Which option would be the best for her if the current inflation rate is 2.5%?
A. bank that offers 4% interest
B. bank that offers 3% interest
C .bank that offers 2.5% interest
D. bank that offers 3.5% interest
Answer:
A
Step-by-step explanation:
You are looking for the highest real interest rate, which is the nominal rate minus the inflation rate. With that being said, the lowest interest rate is 2.5%, which wouldn't make her anything. However, the 4% interest rate yields 1.5% real interest, making it the best option.
The best investment option is the option (A), where the interest rate is 4% which is higher than other options.
What is the interest rate?The amount a lender charges a borrower, expressed as a percentage of the principle, is known as the interest rate.
Given that, the current inflation rate is 2.5%.
Therefore, to make a profitable investment, the interest rate should be more than the inflation rate.
The higher interest rate will give a higher profit.
Therefore, the best investment option is an option (A), where the interest rate is 4% which is higher than other options.
