Order the steps to show how to solve the equation 2(4x−11)+9=19.
Answer:
x=4
Step-by-step explanation:
Distribute the 2 -> 2(4x−11)+9=19 -> 8x-22+9=22
Combine Like Terms -> 8x-13=19
Add 13 to Both Sides -> 8x=32
Divide Both Sides by 8 -> x=4
Sean took out a loan for $1000. He repays $50 twice per month on the
loan. The amount of money Sean owes , y, is a function of the number of
months since he took out the loan, x. Write an equation to model the
situation.
if x=-3 is the only x-incercept of the graph of a quadratic equation which statement best describes the discrinant of the equation
Answer:
The discriminant must be zero.
Step-by-step explanation:
Quadratic Equation
The standard representation of a quadratic function is:
[tex]f(x)=ax^2+bx+c[/tex]
where a,b, and c are constants.
The zeros, roots, or x-intercepts can be found by solving the equation:
[tex]ax^2+bx+c=0[/tex]
We can use the quadratic formula to find the roots:
[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
Note this formula gives us two different roots if the square root is non-zero.
The only way there can be only one x-intercept is because the square root is zero.
If the square root is zero, then
[tex]b^2-4ac =0[/tex]
The expression is called the discriminant.
Thus, if x=-3 is the only x-intercept of the graph of a quadratic function, then the discriminant must be zero.
Find the slope of (2,-3) (-4,7)
Answer:
m = 139167 / 329 = 423 / 1 = 423
Step-by-step explanation:
\displaystyle\int_{-\infty}^\infty e^{-x^2}dx = \sqrt{\pi}
\displaystyle \sum_{n} \frac{1}{n^s} = \prod_{p} {\frac{1}{1 - \frac{1}{p^s}}}
\displaystyle n! = \int_{0}^{\infty} {x^n e^{-x} \,dx}
F(n) = \frac{(\varphi)^n - (-\frac{1}{\varphi})^n}{\sqrt{5}}

After not studying hard enough and losing his academic scholarship, Mark needs to borrow money from 2 different banks to pay
his tuition. Bank Seven charges 12% simple interest, while First Collegiate Bank charges 10%. Mark had to borrow twice as
much from Bank Seven as he did from First Collegiate Bank. After one year, the combined interest he owed was $816. How
much did Mark borrow in total?
9514 1404 393
Answer:
$7200
Step-by-step explanation:
If x is the total amount borrowed, then 2/3x was borrowed from Bank Seven, and 1/3x was borrowed from First Collegiate Bank. The total interest owed was ...
(2/3x)(0.12) +(1/3x)(0.10) = $816
x(2/25 +1/30) = $816
(17/150)x = $816
x = $816(150/17) = $7200
Mark borrowed a total of $7200.

A veterinarian records whether he xlient owns a cat, a dog, neither , or both. If the client owns a dog whatis the probability the client owns a cat
Answer:
hola
Step-by-step explanation:
xddd
The probability that the client owns a cat is 16/35 if a veterinarian records whether the client owns a cat, a dog, neither, or both option (A) is correct.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
It is given that:
The veterinarian records whether the client owns a cat, a dog, neither, or both.
From the table:
Client owns a dog = 35
Owns a cat = 16
Probability that client owns a cat = 16/35
Thus, the probability that the client owns a cat is 16/35 if a veterinarian records whether the client owns a cat, a dog, neither, or both option (A) is correct.

True or False. The domain of the product function (fg (x) consists of all numbers that belong to either the domain of f or the domain of g. Justify your answer.
Answer:
True
Step-by-step explanation:
We want to identify whether the statement that domain of the product functions affects time. You, Becks, consists of all the numbers that are either in the tomato f or in the is correct or not. So, actually, this one is not correct. So we can analyze this in this way. So the product function a makes sense only after effects. And you it means that the domain of the function just consists of on the real numbers that are either not either that our posts in events endeavor. But we can't give a counter example which X equals two. We're back and you're that equals two square. The effort that time is equal to hey, Rita finds the spirit of so consider the case. X equals to one so x equals to one is in the domain of effort. However, the squared of negative one doesn't make any sense. So we still cannot compute the product function every time. So it's not okay to just that acts to be either in the debate over or in the demand, ex have to be imposed the domain of Kiev and effort.
If martha is walking 9meters south and turns and walks 10meters west how far is she from her starting point?
Answer:
She is 13.45 meters from her starting point.
Step-by-step explanation:
Use Pythagorean Theorem (a^2+b^2=c^2) so 9^2+10^2=c^2. Solve it algebraically and you get c= 13.45 (rounded to nearest hundredth).
