Step-by-step explanation:
is -2 a solution for 7x+3=-17-3x ?
Answer:
yes -2 is the correct answer
Step-by-step explanation:
7x+3=-17-3x
7x+3x=-17-3
10x=-20
x=-20/10
x=-2
Answer:
[tex]\boxed{\bold{\huge{\boxed{\sf Yes.}}}}[/tex]
Step-by-step explanation:
=> [tex]\sf 7x+ 3 = -17-3x[/tex]
Combining like terms
=> [tex]\sf 7x+ 3x = -17-3[/tex]
=> [tex]\sf 10x = -20[/tex]
Dividing both sides by 10
=> [tex]\sf x = -2[/tex]
So, -2 is a solution of the given equation.
what is the answer to the equation 8n + 10 = 50 solve for n
Answer: [tex]n=5[/tex]
Add -10 to each side of the equation

Given the graphs of y = f(x) and y = g(x),
g(x) = f(x)
expresses g(x) in terms of f(x).
Step-by-step explanation:
g(x) = f(x) + 4.
This is because g(x) is a translation of f(x) that has been moved up by 4 units. (-2 to 2 when x = 0)
Given the graphs of y = f(x) and y = g(x),
g(x) = f(x) + 3
expresses g(x) in terms of f(x).

Answer:
D. 70
Step-by-step explanation:
if vx is bisector then 3z - 4 = z + 6 add like terms
2z = 10;and z = 5
To find the perimeter we add all side lengths
VU + UW + WV = 5z - 1 + 5z - 1 + 3z - 4 + z + 6 = 14z
we know z = 5 so 14 × 5 = 70

Solve for x.
-6x - 29 = 5x - 7
Answer:
x = -2
Step-by-step explanation:
-6x - 29 = 5x - 7
Add -6x to both sides
-29 = 11x - 7
Add 7 on both sides
-22 = 11x
Divide
[tex]\frac{-22}{11}[/tex] = [tex]\frac{11x}{11}[/tex]
x = -2
Answer:
x = -2
Step-by-step explanation:
move the terms
-6x -5x = -7 + 29collect like terms
-11x = 22
divide both sides of the equation by -11
x = -2Point P is 1/4 of distance from A (-8,-4) to
B (4,0)
Answer:
√10
Step-by-step explanation:
A (-8,-4) to B (4,0) is distance d
d=√(x2-x1)²+(y2-y1)²
d=√(4-(-8))²+(0-(-4))²
d=√12²+4²
d=√144+16 =√160
d=√16*10=4√10
p is 1/4 of distance = 1/4(4√10)=√10

Determina si el número 2,340 es divisible por 2,3,5,9,y 10. Explica tu respuesta.
Answer: The number 2340 is divisible by 2,3,5,9 and 10
=====================================================
Here's why
2340/2 = 1170 is a whole number, so it is divisible by 2
Note how the last digit is an even number, so overall the number is even and divisible by 2
---------------
Add the digits of the given number to get 2+3+4+0 = 9, showing that it is both divisible by 3 and also divisible by 9. If the digits add to a multiple of 3, then it is divisible by 3. If the digits add to a multiple of 9, then it is divisible by 9. Basically anything divisible by 9 is automatically divisible by 3 as well.
We can see we get whole number results shown below
2340/3 = 780
2340/9 = 260
---------------
The last digit is 0, so 2340 is a multiple of 10. It is also a multiple of 5 because 10 = 5*2
And we can see that
2340/5 = 468
2340/10 = 234
Showing 2340 is a multiple of 5 and 10.

Six girls share 5 1/3 pounds of pretzel each one receive the same amount. However, Sue only eats half of her pretzels and leaves the uneaten on the plate . How many pounds does sue leave on her plate?
Answer:
4/9 pounds
Step-by-step explanation:
5 1/3 pounds of pretzels divided equally for 6 girls would mean that each girl gets 8/9 pounds of pretzel.
If Sue ate half of the 8/9 pounds, that would equal to 4/9 pounds of pretzel.

Solve F(x) for the given domain. Include all of your work in your final answer. Submit your solution. F(x) = x2 + 3x - 2
Answer:
F(a) = a² + 3a - 2
F(x-1) = x² + x -4
Step-by-step explanation:
Note:
Domain is missing, assume domain
F(a)
F(x-1)
Given:
F(x) = x² + 3x - 2
Computation:
1. F(x) = x² + 3x - 2
So,
⇒ F(a) = a² + 3a - 2
2. F(x-1) = (x-1)² + 3(x-1) - 2
F(x-1) = x² + 1 -2x + 3x - 3 - 2
F(x-1) = x² + x -4

The value of a is 8.
Option A is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
XZ = XY + YZ
40 = 3a + 8 + a
40 = 4a + 8
40 - 8 = 4a
32 = 4a
a = 32/4
a = 8
Thus,
a is 8.

Answer:
4x^-4/9y^6
Step-by-step explanation:
If the exponent is outside the bracket, it means that all the terms inside will be raised to that exponent. This means that:
(2x^-2 / 3y^3)^2 = 2^2*(x^-2)^2 / 3^2*(y^3)^2
When exponents are raised to an exponent, the exponents are multiplied together, so (x^-2)^2 will = x^(-2*2) = x^-4
Going through:
2^2*(x^-2)^2 / 3^2*(y^3)^2
=4*x^-4 / 9*y^6
=4x^-4/9y^6

Step-by-step explanation:
Which strategie would eliminate a variable in the system of equations? −x+6y=8 7x−y=−2
Answer:
substitution (or addition)
Step-by-step explanation:
A simple strategy for this system is to use substitution. The first equation is easily solved for x, so you could substitute that into the second equation:
x = 6y -8
7(6y -8) -y = -2 . . . . . x variable eliminated
__
The second equation is easily solved for y, so you could substitute that into the first equation.
y = 7x +2
-x +6(7x +2) = 8 . . . . . y-variable eliminated
__
The "addition" method is always a good way to eliminate a variable.
When the coefficient of a variable in one equation is a divisor of the coefficient of that variable in the other equation, a simple multiplication and addition will do.
To make the coefficient of x in the first equation the opposite of the coefficient of x in the second, multiply the first equation by 7. Adding that result to the second equation will eliminate x:
7(-x +6y) +(7x -y) = 7(8) +(-2)
42y -y = 56 -2 . . . . . . x-variable eliminated
Likewise, the second equation can be multiplied by 6 and added to the first to eliminate the y-variable:
(-x +6y) +6(7x -y) = (8) +6(-2)
-x +42x = -4 . . . . . . . . y-variable eliminated
__
It is often the case that using either substitution or "addition" requires about the same amount of work.
Here, the solutions are (x, y) = (-4/41, 54/41).
Kami is cooking dinner for a family reunion that 21 people are attending. If her recipe calls for 1.6 ounces of ground beef per person, how much beef does Kami need altogether?
Answer:
Kami will need 33.6 ounces of ground beef for the recipe
Step-by-step explanation:
From the problem, we know that one person will use up 1.6 ounces of ground beef. We also know that there are 21 people that will be attending the party. Each of those 21 people will definitely use up 1.6 ounces of ground beef.
Hence, for the recipe to be perfect, Kami will have to use 21 X 1.6 ounces = 33.6 ounces of ground to make the recipe for the entire dinner.
