complete the square for x^2+5x
Answer:
(x + [tex]\frac{5}{2}[/tex] )² - [tex]\frac{25}{4}[/tex]
Step-by-step explanation:
Given
x² + 5x
To complete the square
add/ subtract ( half the coefficient of the x- term )² to x² + 5x
= x² + 2([tex]\frac{5}{2}[/tex] )x + [tex]\frac{25}{4}[/tex] - [tex]\frac{25}{4}[/tex]
= (x + [tex]\frac{5}{2}[/tex] )² - [tex]\frac{25}{4}[/tex]

If neither a nor bare equal to zero, which answer most accurately describes the product of (a + b)(a - b)?
Answer:
a² - b²
Step-by-step explanation:
We can recognize (a + b)(a - b) as a difference of squares.
Step 1: Write expression
(a + b)(a - b)
Step 2: FOIL (Expand)
a² - ab + ab - b²
Step 3: Combine like terms
a² - b²

why is 2 times 3/4 less then 2
since 3/4 is less than one. if the number is less than one, it will always result in a smaller number. And anything multiplied to one is the other number.

peter, henry and john shared $345 between them. Peter received $45, henry received $75 and john received the rest.
a) find the ratio of peters share to henrys share to johns share
Answer:
Step-by-step explanation:
Let J = John's share ($)
P = Peter's share ($)
H = Henry's share ($)
1) H = P + 80
2) J/P = 6/3 = 2
3) P/H = 3/5
Substitute equation 1) into equation 3)
P/(P + 80) = 3/5 (multiply both sides by (P + 80)
P = (3/5)*(P + 80) (multiply both sides by 5)
5*P = 3*P + 240
2*P = 240
P = 240/2 = $120
Substitute P value into equation 2)
J/P = 2 or
J = 2*P = 2*$120 = $240
John received $240

Step-by-step explanation:
A frozen yogurt shop offers a rewards system for frequent customers. The graph below represents how much a rewards customer pays based on the number of ounces of frozen yogurt purchased.
A graph titled Customer Rewards. The horizontal axis shows ounces of yogurt purchased, numbered 2 to 22, and the vertical axis shows Total Spent (dollars) numbered 1 to 11. A line begins at 0, extends to 5 dollars spent at 10 to 12 ounces, and ends at 9 dollars spent at 20 ounces.
Which statement describes the total amount a rewards customer pays for 10 ounces and 12 ounces of yogurt?
A rewards customer earns 2 free ounces of yogurt because the total amount paid for 10 ounces and 12 ounces is the same.
A rewards customer pays $5 per ounce because the total amount paid is always increasing.
A rewards customer pays $20 for 10 or 12 ounces of yogurt because the total amount paid is increasing.
A rewards customer earns 5 free ounces of yogurt because the total amount paid for 10 ounces and 12 ounces is the same.
Answer:
A rewards customer earns 2 free ounces of yogurt because the total amount paid for 10 ounces and 12 ounces is the same.

Answer:
44 degrees
Step-by-step explanation:
Triangles ABC and DBC are congruent (as said in the question), that would make the corresponding parts of the two triangles congruent.
Answer:
Angle D = 44° (degrees)
Step-by-step explanation:
given that ∆ABC is congruent to ∆DBC, AB = 10, and Angle A = 44°. Angle D must be 44° as well since you can tell that angle abc is 88° and is not a right angle, and due to the corresponding parts. You can also think about these triangle as angles since angle abc = angle dbc. The other angles can be calculated using the triangle sum theorem since both triangles share side bc so angle acb and dcb are right angles(90°)
therefore 180-(44+90) = 46° which the measure of angles abc and dcb.
This measure would only make it true because of triangle congruency.
f(x) = -2x + 5
f ( ) = 13
Answer:
Okay, I haven't done this a long time however I believe with this you have to solve the equation by doing substitution.
Step-by-step explanation:
so, if f (x) equals 13, you replace the x in the equation to 13.
f(x)=-2x+5
f(x)=-2(13)+5
f(x)=26+5
f(x)=31
I believe 41 would be your answer. Hope this is right and it helped!

Ingrid's curtain company is making curtains for a local hotel. She wants each curtain to be 36 inches long. At the fabric store, fabric is sold by the foot. If Ingrid's curtain company wants to make 64 curtains, how many feet of fabric will she need? 1 inch = 1 12 foot I just don't get it
Answer:
192 ft
Step-by-step explanation:
Number of curtains = 64
Length of each curtains = 36 inches
Total length of curtains = Number of curtains × Length of each curtains
= 64 × 36 inches
= 2,304 inches
1 inch = 1/12 foot
2,304 inches = 2,304 / 12 ft
2,304 inches = 192 ft
She will need 192 ft of the fabric to make 64 curtains each of length 36 inches
write an equation of the line that passes through the points:
(0,0), (4,-2)
Find the slope of the line that passes though (9,8) and (7,5)
Answer:
I think its m=3/2
Step-by-step explanation:
If it right can I please have brainliest :)
Answer:
here is how to figure this out
Step-by-step explanation:
point 1 = (9,8) = (x1,y1)
point 2 =(7,5) = (x2,y2)
slope= y2-y1 / x2-x1
slope = 5-8 / 7-9
slope = -3 / -2
slope = 3/2 :)
