How is the intersection point of two linear functions related to solving
a linear equation?
Answer:
Linear equation formed by equating both functions is used to find the x-coordinate of the intersection point.
Step-by-step explanation:
If we have two linear functions f(x) and g(x) which are intersecting at a point (a,b), then equating both functions we get a linear equation as
[tex]f(x)=g(x)=y[/tex]
On solving this linear equation we get the x-coordinate of the point of intersection, i.e., x=a.
After that, we need to substitute x=a in either f(x) or g(x) to get the y-coordinate of the point of intersection.
Therefore, the linear equation formed by equating both functions is used to find the x-coordinate of the intersection point.
Solve using zero product property: 2x^2-5x-6=0
Answer:
x = (5 + √73) / 4 or (5 - √73) / 4
Step-by-step explanation:
2x² - 5x - 6 = 0
x = [5 ± √(25 - 4(2)(-6)] / 2(2)
x = [5 ± √(25 + 48)] / 4
x = [5 ± √(73)] / 4
x = (5 + √73) / 4 or (5 - √73) / 4)

what is - 5у - 25 = -40
Answer:
x=4
-5y+8x=-18
linear combination:
cancel out -5y with 5y. combine 8x and 2x
5y+2x=58
10x. combine -18 and 58 to get 40
10x=40
40/10=4
So that means..x=4

Write a simplified expression for the length of QR.
HELP ME PLASE
Answer/Step-by-step explanation:
Length of AC:
Given that AB = x + 2, and BC = 7x - 3, therefore,
[tex] (x + 2) + (7x - 3) = AC [/tex] (segment addition postulate)
Simply the expression for the length of segment AC
[tex] x + 2 + 7x - 3 = AC [/tex]
Collect like terms
[tex] x + 7x + 2 - 3 = AC [/tex]
[tex] 8x - 1 = AC [/tex]
Length of QR:
Given that PQ = 8y + 5, and PR = 13y + 25, therefore,
QR = (13y + 25) - (8y + 5) (PQ + QR = PR)
Simplify the expression to for the length of segment QR
QR = 13y + 25 - 8y - 5
Collect like terms
QR = 13y - 8y + 25 - 5
QR = 5y + 20

You earn $28 for washing 7 cars. How much do you earn for washing 6 cars?
━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━
Since you can earn 28 dollars by washing 7 cars, and you want to find the amount money you can make by washing 6 cars.
[tex]\frac{28}{7} = \frac{x}{6}[/tex]
First, you should find the amount of money you can make by washing 1 car (unit rate).
[tex]\frac{28}{7} = \frac{x}{1}[/tex]
To get from 7 to 1, you have to divide 7 by 7; 7 ÷ 7 = 1.
Do the same thing to the numerator; 28 ÷ 7 = 4.
Now you know how much you make by washing 1 car, you need to find how much you make by washing 6 cars.
[tex]\frac{4}{1} = \frac{x}{6}[/tex]
To get from 1 to 6, you multiply by 6. 1 times 6 equals 6.
Now do the same thing to the numerator; 4 × 6 = 24.
You can earn 24 dollars by washing 6 cars.

you have 5814 meters of rope that you need to cut into 27 meters sections. How many 27 meter section of rope will you be able to create, and how much rope will be left over as waste?
Answer:
215 sections of 27 meters of rope will be created and 9 meters will be left as waste
Step-by-step explanation:
A rope that is 5814 meters long needs to be cut into 27 sections
The number of 27 meter sections of rope that can be created can be calculated by dividing 5814 by 27
= 5814/27
= 215 remainder 9
Hence 215 sections of rope will be created and 9 meters of rope will be left as waste
Jacob is a construction
worker who earns a yearly income given by the expression 2000x + 4000, where X is the number of hours
he works each week. Carlos works with Jacob and earns a yearly income given by the expression 3500x - 40000. A manager
predicts that if Carlos and jacob each work 35 hours, they will earn the same amount of money,
Answer:
The manager's prediction is false
Step-by-step explanation:
Given
Jacob: 2000x + 4000
Carlos: 3500x - 40000
Required
Determine if both expression will be the same if x = 35
To do this;
Equate both expressions and then solve for x
i.e.
[tex]2000x + 4000 = 3500x - 40000[/tex]
Collect Like Terms
[tex]2000x - 3500x = -4000 - 40000[/tex]
[tex]-1500x = -44000[/tex]
Divide both sides by -1500
[tex]\frac{-1500x}{-1500} = \frac{-44000}{-1500}[/tex]
[tex]x = \frac{-44000}{-1500}[/tex]
[tex]x - 29.3[/tex]
Hence, the manager's prediction is not true because [tex]x \neq 35[/tex]

A 0.05-kg car starts from rest at a height of 0.95 m. Assuming no friction, what is the kinetic energy of the car when it reaches the bottom of the hill? (Assume g = 9.81 m/s2.) i dont understand can i get some help?
Answer:
The kinetic energy of the car is 0.466 J
Correct Answer: A. 0.466 J Explanation: If there is no friction, all of the gravitational potential energy of the car at the top of the hill will be converted to kinetic energy at the bottom of the hill. The potential energy of the car is equal to the product of its mass, height, and gravitational acceleration.0.05 kg • 0.95 m • 9.81 m/s2 = 0.466 J.

If p - q = 4 and p² - q² = 24, what is the value of p + q?
Answer:
p=5, q=1
Step-by-step explanation:
5-1=4, 5^2-1^2=24
25-1=24
24=24
I just guessed and checked the solution for the answer
Answer:
p + q = 6
Step-by-step explanation:
p² - q² ← is a difference of squares and factors as
p² - q² = (p - q)(p + q) , then
p² - q² = 4(p + q) = 24 ( divide both sides by 4 )
p + q = 6

Answer: dark blue
8 for a cd and start with $15
Step-by-step explanation: Here, notice that the value that we
don't know is how many CDs are purchased.
Since CD's cost $8, we multiply 8 by our variable, which is x.
So we have 8 times x or 8x.
In addition, since there is a one time fee
of $15 to begin, we add 15 to 8x.
So we have 8x + 15.

which of the following polynomials is in standard form (Picture)
Answer:
D
Step-by-step explanation:
A polynomial in standard form has the terms in ascending order.
In other words, the term with the largest degree is on the left, followed by the term with the second largest degree, etc.
The largest term in this polynomial is 2x³. Thus, we need to start with that.
The only choice that starts with 2x³ is choice D.
Thus, choice D is in standard form.
And examining choice D, we see that it is in ascending order all the way through.

What is equation?Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S.
There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators. An equation can be formed without these as well, for example, 5 + 10 = 15.

Step-by-step explanation:
here,
the lower angle when sumed,
it is like: 154+a=180 (let angle be a) being supplementary angle sum is 180

the above angle x is corresponding to angle a (a=x)
So value x is 26
Solve for q. |q+8|≥2 Write a compound inequality like 1 < x < 3 or like x < 1 or x > 3. Use integers, proper fractions, or improper fractions in simplest form.
Answer:
-6≤q≤-10Step-by-step explanation:
Given the inequality |q+8|≥2, we are to solve for q. Note that the function inside modulus sign will return both negative and positive value.
For the positive function:
q+8≥2
Subtract 8 from both sides of the inequality.
q+8-8≥2-8
q ≥ -6
For the negative function;
-(q+8)≥2
open the parenthesis
-q-8≥2
add 8 to both sides
-q-8+8≥2+8
-q≥10
Multiply both sides by -1. Note that multiplying both sides of an inequality changes the direction of the inequality sign.
q≤-10
Combining both results i.e q ≥ -6 and q≤-10
q ≥ -6 can also be written as -6≤q
Combining -6≤q with q≤-10, this will give -6≤q≤-10.
Hence the result of the inequality function given is -6≤q≤-10.
are the expressions 2(3x - 6) and 2(3x)x - 6 are equivalent
Answer:
No
Step-by-step explanation:
So lets do the first expression first
2(3x-6)
6x-6
So the first one is 6x-6
Now the second expression
2(3x)x-6
As you can see here, there's an extra x in this problem compared to the last problem, but lets still work it out
6x*x-6
So they are different.
If the extra x wasn't there then it would've worked.
