Subtract 2x^2+ 6x - 5 from 7x^2+ 3x + 4.
Answers
Answer:
− 5[tex]x^{2}[/tex] + 13x −6
By subtracting "[tex]2x^2+ 6x - 5[/tex]" from "[tex]7x^2+ 3x + 4[/tex]" we get "[tex]5x^2-3x+9[/tex]". A further solution is below.
Given equations are:
→ [tex]2x^2+6x-5[/tex]...(equation 1)
→ [tex]7x^2+3x+4[/tex]...(equation 2)
By subtracting "equation 1" from "equation 2", we get
→ [tex](7x^2+ 3x + 4)-( 2x^2+ 6x - 5)[/tex]
→ [tex]7x^2+3x+4-2x^2-6x+5[/tex]
→ [tex]5x^2-3x+9[/tex]
Thus the above solution is the appropriate one.

Awnser: tan theta 15/8.
Step-by-step explanation:
AC = 17
AB = 15
BC = ?
By Pythagoras theorem:
AC² = AB² + BC²
17² = 15² + BC²
289 = 225 + BC²
BC² = 289 – 225
BC² = 64
BC = √64
BC = 8
The value of tanθ = 15/8

There are two routes Lucas can take to walk to school. Route A is 2 and StartFraction 1 over 8 EndFraction miles and is StartFraction 3 over 8 EndFraction mile longer than route B. The equation b + StartFraction 3 over 8 EndFraction = 2 and StartFraction 1 over 8 EndFraction can be used to represent this situation, where b is the length of route B. How many miles will Lucas walk if he takes route B?
1 and one-half miles
1 and three-fourths miles
2 and one-fourthmiles
2 and one-half miles
Answers
Answer:
I know im late, but it would be B!
Answer:
If Lucas walks through route B, the length of route B is 1 and 3/4 miles. Then the correct option is B.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

do anyone know the answer?
Answers
Answer:
C.
Step-by-step explanation:
To find which table is correct, you first have to plot the graph. First, pick some easy points on the X axis to graph. Some of these points could be -4, 0 and 4. Now you need to fill in the equation.
Y = -1/2*-4 - 2 = 0
Y = -1/2*0 - 2 = -2
Y = -1/2*4 - 2 = -4
Now you can plot the points and draw your line. Once you have done this, you check each table and see if all the points match up. Doing so would give you answer C.
Also the graph from the equation can be seen below

Step-by-step explanation:
Answer:
[tex]2\sqrt{13}[/tex]
Step-by-step explanation:
Square root of 52
_________________
When finding square root, we always have to find one number that multiplies by itself twice to get the number in the square root.
No number does this for 52, so we have to use the GCF prime, which is :
[tex]\sqrt{2^2} \sqrt{13}[/tex]
Apply the radical rule for [tex]\sqrt{2^2}[/tex] :
[tex]\sqrt{2^2} =2[/tex]
Therefore :
[tex]2\sqrt{13}[/tex]

how do I simify by combining like terms
Answers
Answer: Like terms are combined together in algebraic expression so that the result of the expression can be calculated with ease. For example, 7xy + 6y + 6xy is an algebraic equation who's like terms are 7xy and 6xy. Therefore, this expression can be simplified by combining like terms as 7xy + 6xy + 6y = 13xy + y.
Step-by-step explanation:
Answer:
If in a equation there are numbers that have the same letters you can just add them or subtract them depending on the signs.
Step-by-step explanation:
For example this equation:
2x + 7b - 7x + 9b + 1a - 22a
So you just put them in different categories(Remember to bring them with the sign that's in front of each number) after that you just add or subtract them
category x(only numbers that have x's go here): +2x-7x = -5x
category b (only numbers that have b's go here): +7b+9b = +16b
category a (only numbers that have a go here): +1s-22b = -21a
now just put them in the same equation:
-5x+16-21a
and done!^^

A car dealership increased the price of a certain car by 13%. The original price was $47400 what is the new price?
Answers
Answer:
Step-by-step explanation:
To get the new price of the car multiply the original price by the percent increase in decimal form +1. 11% in decimal form is 0.11 = 11/100. Add one to this and you get 1.11 = 1 + 0.11. So now multiply $49,800 * 1.11 = $55,278. If the problem had said they decreased the price by 11% you would use 1 - 0.11 = 0.89 because 89% is 11% less than 100%.
