Answer:
63
Step-by-step explanation:
6x + 3y - 9
x = 6
y = 9
6(6) + 3(9)
36 + 27
= 63
Evaluate each function. Step by step.
1) k(t) = -2|3t| + 2; Find k(-5)
2) g(n)=-3n^2+3+2n; Find g(-3)
Answer:
Substitute what t and n equals to in the equation and just solve using algebra.
So number 2, plug in -3 where ever the variable N is located in and solve.
g(-3) = 3(-3)^2+3+2(-3) ---> g(-3) = 27+3-6 ---> g(-3) = 24 That's the answer for 2.
For 1
plug in -5 into the t variable and solve.
k(t) = -2 |3(-5)| + 2 Since the || is between the 3 and 5, answer will be positive.
k(t) = -2(15)+2
k(t) = -28

Find the perimeter of a triangle if the three sides are
4x^2-x+4, 2x^2-2x+1, x^2+8x+3
Answer:
7x^2+5x+8
Step-by-step explanation:
Perimeter = sum of all sides
Perimeter = 4x^2-x+4+2x^2-2x+1+x^2+8x+3
= 7x^2+5x+8

Jim's cat can run 4 blocks in 15 seconds. Juanita says one of her cats can run 3 blocks in 11
seconds. Who has the fastest cat? How did you decide?
Answer:
Juanita's cat is faster because it can run more blocks in a second
Step-by-step explanation:
Take the number of blocks and divide by the number of seconds
Jim:
4 blocks/ 15 seconds
.26666.... block per second
Juanita
3 blocks / 11 seconds
.2727...... blocks per second
Juanita's cat is faster because it can run more blocks in a second

Answer:Complete the question pls
Step-by-step explanation:
Which of the following equations has a slope of 3?
O 6x - 2y = 5
O 3x + 4y = 12
O y = 4x + 3
The answer 6x - 2y = 5
Step-by-step explanation:
The general formula of linear equations is y = mx + c
where m is the slope
so when we put this in the general form, it will be
-2y = -6x + 5
y = 3x - 5/2
and so the slope is 3
4 1/2 ÷(−1 3/7 ) please help and hurry
Hi! I'm happy to help!
To first solve this, we need to make those mixed numbers improper fractions.
To make 4 1/2 an improper fraction, you have to turn 4 into halves (multiply four by 2) then add the extra half, giving you 9/2.
[tex]\frac{9}{2}[/tex] ÷(−1[tex]\frac{3}{7}[/tex] )
Now, we turn 1 3/7 into an improper fraction. We turn 1 into sevenths (multiply 1 by 7) then add the other 3 sevenths, giving you 10/7.
[tex]\frac{9}{2}[/tex] ÷(−[tex]\frac{10}{7}[/tex] )
From here, we need to turn this problem into a multiplication problem in order to solve. Since multiplication is the opposite of division, we need to get the opposite of something, so we use our second fraction and flip it.
[tex]\frac{9}{2}[/tex] ×(−[tex]\frac{7}{10}[/tex] )
Now, we multiply the top by the top, and the bottom by the bottom. (any positive multiplied by a negative gives a negative)
-[tex]\frac{63}{20}[/tex]
Since we cannot simplify, our final answer is -63/20.

Find the length of the third side of the right triangle. Give an exact answer and an approximation to three decimal places if needed.
Answer:
a = 32
Step-by-step explanation:
This is a right triangle and the square value of hypotenuse is equal to sum of square value of other two side lengths
68^2 = 60^2 + a^2
4624 = 3600 + a^2
4624 - 3600 = a^2
1024 = a^2 find the root for both sides
32 = a

ALGEBRA 2:
Justify the equation by stating one of the properties of real numbers.
x + (37 + (-37)) = x + 0
Answer:
The property is the neutral element, in this case, it's the 0
The equation is justified using the additive inverse property of real numbers. The equation [tex]\(x + (37 + (-37)) = x + 0\)[/tex] is justified by the additive inverse property of real numbers.
According to the additive inverse property, for any real number a, there exists another real number -a such that their sum is equal to zero:
[tex]\(a + (-a) = 0\)[/tex]
In the given equation, 37 and -37 are additive inverses of each other, meaning [tex]\(37 + (-37) = 0\).[/tex] Therefore, the equation simplifies to:
[tex]\(x + (37 + (-37)) = x + 0\)\(x + 0 = x\)[/tex]
So, the equation is justified using the additive inverse property of real numbers.

Which is a prime number?
A.0
B.1
C.3
D.9
Answer:
3
Step-by-step explanation:
NotePrime numbers are numbers that have two factors thus 1 and the number itself . Example; 2 ,3,5 ,7 and 11
BesidesAlso 0 and 1 is not a prime number
Answer:
C. [tex]\displaystyle 3[/tex]
Step-by-step explanation:
Prime Numbers consist of two factours -- 1 and that number. Just so you know, you can AUTOMATICALLY eliminate the first two choises because those two numbers are not composite nor prime. Now, I can predict that your next lesson will probably be about prime factorisation, in which you have to find the prime factorisation of numbers, using two methods:
Factour TreeLadder DiagramFactour Tree Ladder Diagram
3 3|3
| ⁻⁻
3 1
Factour Tree Ladder Diagram
9 3|9
/\ ⁻⁻
3 3 3|3

So, the prime factorisation of 9 is [tex]\displaystyle 3^2,[/tex]and the prime factorisation of 3 is 3.
