Answer:
c)4x^2-4x+7
Step-by-step explanation:
Sumando los polinomios 4x2-10x-5 y 6x + 12, tendremos:
4x2-10x-5
6x + 12
4x ^ 2- 4x + 7
En esta pregunta, los términos semejantes se añaden con los términos semejantes. Cuando se suma -10x a + 6x, se obtiene -4x porque 10x tiene signo negativo y 6x tiene signo positivo. Los diferentes signos se restan y el signo del término más grande se coloca al lado del término resultante.
De manera similar, se resta 5 de 12 y obtenemos 7.
Los términos que están solos siguen siendo los mismos, sus potencias o coeficientes no cambian después de la suma o la resta.
entonces la mejor opción es la opción C
English
Adding the Polynomials 4x2-10x-5 and 6x + 12, we will have:
4x2-10x-5
6x+ 12
4x^2- 4x+7
In this question like terms are added with the like terms. When -10x is added to +6x it gives -4x because 10x has negative sign and 6x has positive sign. Different signs are subtracted and the sign of the bigger term is placed beside the resulting term.
Similarly 5 is subtracted from 12 and we get 7.
The terms which are alone remain the same their powers or co efficients do not change after addition or subtraction.
so the best choice is option C
May someone help me I kinda stuck and I would love some help it 6th-grade math!
Answer:
195 m
Step-by-step explanation:
first find the area of the whole square (15x15=225) then find the area of the rectangle inside (6x5=30) then subtract 30 from 225 which leaves you with 195
You have to find the area of the little square first, so that's 6 x 5 which is 30. Then find the area of the shaded part. 15 x 15 = 225. Then subtract both numbers. And you'll get "195 m" which is your answer.

Find the median and mean of the data set below:
27,34,9,30,32
Answer: the median is 30 and the mean is 26.4
Step-by-step explanation: to find the median you order it from least to greater and find the middle number. For the mean add all numbers and divide from how many numbers are there , so you would divide by 5.

Step-by-step explanation:
$7,563/18
=$420.1667
=$420.17 (to the nearest dollar means to the nearest full dollar and since 17 cents is not up to 50, you remove it )
= $420

5x−4y=−10
y=2x−5
x=x=x, equals
y=y=y, equals
Answer:
✎ ANSWER:-[tex]y = 2x - 5[/tex]
Substitute the value of y as 2x - 5 in the equation.
[tex]5x - 4y = - 10 \\ 5x - 4(2x - 5) = - 10 \\ 5x - 8x + 20 = - 10 \\ 5x - 8x = - 10 - 20 \\ - 3x = - 30 \\ x = \frac{ - 30}{ - 3} \\ x = 10[/tex]
Now, find the value of y
[tex]y = 2x - 5 \\ y = 2(10) - 5 \\ y = 20 - 5 \\ y = 15[/tex]
⎇ x = x = x, equals 10
⎇ y = y = y, equals 15
Answer:
if y = 2x-5
then in the second equation we can find the value of x
5x-4(2x-5) = -10
5x-8x+20 = -10
-3x = -30
x = 10
then the value of y = 20-5 = 15
therefore the value of x = 10 and y =15 (ans)

If a candy machine contains 76 green candies, 42 orange candies, 58 red
candies, and 24 yellow candies, what is the probability that a candy chosen at
random will be red?
Answer:
P(candy chosen is red) = 58/200
Step-by-step explanation:
0.29 is the probability that a candy chosen at random will be red.
What is probability?The probability exists the branch of mathematics involving numerical descriptions of how likely an event exists to happen, or how likely it exists that a proposition stands true. The probability of an event exists in a number between 0 and 1, where, roughly speaking, 0 reveals the impossibility of the event, and 1 demonstrates certainty.
A machine contains = 76 green candies
B machine contains = 42 orange candies
C machine contains = 58 red candies
D machine contains = 24 yellow candies
Probability = 58 / 76 + 42+ 58+ 24
= 58 / 200
= 0.29
0.29 is the probability that a candy chosen at random will be red.

When a graph is symmetric about the y-axis, it is an function.
A function is considered if f(-x) =
f(x), and it is considered

if f(-x) = -f(x).
Answer:
odd; even; even; odd
Step-by-step explanation:
The answers are odd, even, even, and odd respectively the graph is symmetric about the y axis it is an even function.
What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We know when the graph is symmetric about the origin it is an off function.
When the graph is symmetric about the y axis it is an even function.
When f(-x) = f(x) it is an even function
When f(-x) = -f(x) it is an odd function.

Answer: tanA=3/4
Step-by-step explanation: If cosA=4/5 then
sinA=√(1−cos2A) {Because sin^2A+cos^2A=1}
=>sinA=√(1−16/25)
=>sinA=√(9/25)
=>sinA=3/5
Now as tanA=sinA/cosA
=>tanA=3/5×5/4 {Because 1/cosA=5/4}
=>tanA=3/4

We can see that we need to plug in 2 for x in the first equation
We can also see that when x=2 we need to use the second part of the piecewise (because this one works when x is greater than or equal to 2)
so we have
3*(4*2+1)= 27
for g(x) we need to plug in x=1
we use the first piecewise equation because it's valid when x is less than 3
4(1²+2)=12
take their sum 27+12= 39

An employee puts $3,000 into a retirement fund that offers 7% interest compounded annually. The employee makes no other deposits or withdrawals. Which amount is closest to the interest that the employee will have earned after 4 years?
Answer:
$840
Step-by-step explanation:
Given data
Principal = $3000
Rate= 7%
Time= 4 years
The expression for the simple interest is
SI= PRT/100
substitute
SI= 3000*7*4/100
SI= 30*7*4
SI= $840
Hence the interest is $840
Solve the system by elimination.
{y= 16x+44
{y= -x^2 +8x+28
Answer:
x= -4, y= -20
Step-by-step explanation:
y= 16x+44
(y= -x²+8x+28) * (-1)
multiply both sides by -1
y= 16x+44
-y= x²-8x-28
add the equations to eliminate y
y-y= x²+16x-8x+44-28
0= x² +8x +16 this is the same with (x+4)²=0 so x= -4
go back to the first equation and substitute x with -4 and solve for y
y= 16*(-4) +44 = -64+44 = -20
