Answer:
"The values for y are square roots of negative numbers"
Step-by-step explanation:
The steps shown are correct. But at the end we can see that we have to "take the negative square roots".
This means we have to take the square root of -1. In the real number system, we CANNOT take the square root of any negative number. Hence, there is NO SOLUTION to the system.
2nd answer choice, "The values for y are square roots of negative numbers", is right.

How do I solve? (10y+9)-(4y-8)=
Answer:
(6y+17)
Step-by-step explanation:
1. Subtract 4y from 10y to get 6y
2. 9 is positive and 8 is negative but to subtract a negative is basically adding so you would add 9 to 8
3. You final equation would be (6y+17)
4. (10y+9)-(4y-8)= (6y+17)
Answer:
(10y + 9) - (4y - 8) = 6y + 17Step-by-step explanation:

Answer:
y = - [tex]\frac{1}{4}[/tex] x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = - [tex]\frac{1}{4}[/tex], hence
y = - [tex]\frac{1}{4}[/tex] x + c ← is the partial equation
To find c substitute (12, 2) into the partial equation
2 = - 3 + c ⇒ c = 2 + 3 = 5
y = - [tex]\frac{1}{4}[/tex] x + 5 ← equation of line
What is the slope of the line?
The slope is

What is the product of (2x^2+5x-3) and (3x+7)
Answer: option D.
Step-by-step explanation:
To solve this exercise you must apply the proccedure shown below:
- Apply the Distributive property (Remember that when you multiply two powers with the same base, you must add the exponents).
[tex]b^m*b^n=b^{(m+n)}[/tex]
- Add the like terms.
Therefore, you obtain that the product is:
[tex](2x^2+5x-3)(3x+7)=6x^3+14x^2+15x^2+35x-9x-21\\=6x^3+29x^2+26x-21[/tex]
An expression is defined as a set of numbers, variables, and mathematical operations. The product of (2x²+5x-3) and (3x+7) is 6x³ + 29x² + 26x - 21.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The product of (2x²+5x-3) and (3x+7) can be done as,
(2x²+5x-3) × (3x+7)
= 3x(2x²+5x-3) + 7(2x²+5x-3)
= 6x³ + 15x² - 9x + 14x² + 35x - 21
= 6x³ + 29x² + 26x - 21
Hence, the product of (2x²+5x-3) and (3x+7) is 6x³ + 29x² + 26x - 21.

Find the value of y. Round answer to the nearest tenth if needed
Answer:
y = 54.1
Step-by-step explanation:
The big triangle is divided in two: one on the left and one on the right. Lets start working with the right one.
We know the right triangle is a right triangle with legs 24 and 36, so we can use Pitagoras to find the hypotenuse (h), in a way that:
24^2 + 36^2 = h^2
1872 = h^2
Applying sqr root in both sides:
h = 43.27
So, the hypotenuse measures 43.27 or 43.3.
Now lets do the same with the triangle of the right which legs are 36 and y, lets find it hypotenuse (g):
36^2 + y^2 = g^2
1296 + y^2 = g^2
Now we will pass to the large triangle, which is composed by the left and the right triangles and has legs of 43.3 and g, and the hypotenuse is 24+y. Lets apply Pitagoras:
43.3^2 + g^2 = (24+y)^2
1875 + 1296 + y^2 = 24^2 + 48y + y^2
3171 + y^2 = 576 + 48y + y^2
As we have y^2 in both sides we can eliminate them
3171 + = 576 + 48y
Now subtract 576 in both sides:
3171 -576 = 576 + 48y - 576
2595 = 48y
Divide both sides by 48:
2595/48 = 48y/48
54.1 = y
So, the large hypotenuse measures 54.1+24 = 78.1. Lets verify:
43.3 ^2 + 1296 + 54.2^2 = 6,108.53
And the sqrd root of 6,108.53 is approximately 78.1. Verified!!!!
So, we can confirm: y = 54.1
There are 5 red pens,3 blue pens and 2 green pens in a box. Gary takes at random a pen from the box and gives the pen to his friend. Gary then takes at random another pen from the box . work out the probability that both pens are the same colour.
please help
➷ Find the total number of pens:
5 + 3 + 2 = 10
The probability of taking a red the first time is 5/10
The probability of taking a blue the first time is 3/10
The probability of taking a green the first time is 2/10
If you want to take the same colored pen again, there would be 1 less of the total pen (as it hasn't been replaced) and there would be one less of that color (as one has already been taken)
Therefore:
The probability of taking a red again is 4/9
The probability of taking a blue again is 2/9
The probability of taking a green again is 1/9
Multiply the values for the same color together:
5/10 x 4/9 = 20/90
3/10 x 2/9 = 6/90
2/10 x 1/9 = 2/90
Add these values together:
20/90 + 6/90 + 2/90 = 28/90
Your answer is 28/90

The area is a rectangle is 56 cm. The length is 2 cm more than x and the width is 5 cm less than twice x. Round to the nearest whole number.
Answer:
The solution is [tex]x=6\ cm[/tex]
Step-by-step explanation:
we know that
The area of rectangle is equal to
[tex]A=LW[/tex]
we have
[tex]A=56\ cm^{2}[/tex]
so
[tex]56=LW[/tex] ------> equation A
[tex]L=x+2[/tex] -----> equation B
[tex]W=2x-5[/tex] -----> equation C
Substitute equation B and equation C in equation A
[tex]56=(x+2)(2x-5)[/tex]
solve for x
[tex]56=(x+2)(2x-5)\\56=2x^{2}-5x+4x-10\\2x^{2}-x-66=0[/tex]

what is the solution set for |x/2|=8
Answer:
The correct answer option is x = -16 and x = 16.
Step-by-step explanation:
We are given the following equation and we are to find the solution for this equation:
[tex] | \frac { x } { 2 } | = 8 [/tex]
For the given equation, involving the modulus, we will have a positive as well as a negative value for it in order to find its solution set.
[tex] \frac { x } { 2 } = - 8 [/tex] and [tex] \frac { x } { 2 } = 8 [/tex]
[tex] x = 8 \times 2 [/tex] and [tex] x = - 8 \times 2 [/tex]
x = -16 and x = 16
Answer:
The correct answer is last option
x = -16 or x = 16
Step-by-step explanation:
it is given that,
|x/2| = 8
To find the solution set
From this we can understand that , the value of x/2 = - 8 or x/2 = 8
If x/2 = -8 then x = -8 * 2 = = -16
If x/2 = 8 then x = 8 * 2 = 16
Therefore the solutions are
x = -16 or x = 16
how do I simplify 15x+42-8y+20-4x
Answer:
[tex]\large\boxed{15x+42-8y+20-4x=11x-8y+62}[/tex]
Step-by-step explanation:
[tex]15x+42-8y+20-4x\\\\\text{combine like terms}\\\\=(15x-4x)-8y+(42+20)\\\\=11x-8y+62[/tex]
You add like terms together.
Ex. You would add 15x and(-4x) together, giving you 11x
So to simplify it, you need to do 15x-4x, 42+20, and 8y would be left by itself since there are no like terms for 8y.
So the simplified version would be: 11x+62+8y
how do I find the x value of this triangle? thank youuuu
answer = 42
if you look at the triangle you see a small square in the corner indicating that the triangle is a 90 degree angle, therefore all the sides add up to 90. With this knowledge just add the values of the two known sides, 18 and 30, which is 48 and then subtract 48 from 90 which gives you the value of x, 42

During the spring and summer months, the Happy Home Motel sees a rise in travelers. The manager of the motel turned in this report of how many travelers stayed at the Happy Home Motel. Month Number of Travelers March 217 April 232 May 252 June 277 July 307 August ? If the Happy Home Motel continues to follow this pattern, how many travelers will stay during August?
Answer:
342
Step-by-step explanation:
Let's see the difference is each successive values:
232 - 217 = 15
252 - 232 = 20
277 - 252 = 25
307 - 277 = 30
As we can see, each month the increase is 5 more than previous months' increase. Clearly from the pattern we can surmise that the next month (August), it will increase by 35 from the value of July.
Number of visitors in August = Number of Visitors in July + 35 = 307 + 35 = 342

I need help plz show steps
Answer:
D
Step-by-step explanation:
We will solve the equation by using quadratic formula.
x= (-b ± √(b^2-4ac))/2a
The standard form of quadratic equation is:
ax^2+bx+c=0
So by comparing with the standard form, we get:
a=1
b= -4
c=18
Putting the values in the formula
x= (-(-4)± √((-4)^2-4(1)(18)))/2(1)
x = (4± √(16-72))/2
x = (4± √(-56))/2
The minus sign in square root will introduce the imaginary symbol.
x = (4± √(14*4*(-1)))/2
The minus 1 can be replace by the imaginary i => i^2 = -1
x = (4± √(14*2^2*i^2 ))/2
The terms with squares can be brought out of the square root
So,
x = (4± 2i√14)/2
Taking 2 as common
x = (2(2± i√(14)))/2
x = 2± i√14
