Answer:
Step-by-step explanation:
Use identity : (a + b)² =a² + 2ab + b²
49m⁴ + 140m² + 100 = 7²(m²)² + 2 * 7m² * 10 + 10²
= (7m²)² + 2 *7m²*10 + 10²
= (7m² + 10)²
= (7m² + 10)(7m² + 10)

In the park, there are some cats and dogs. The number of cats’ feet is double the number of the dogs’ noses. The number of cats is how many times the number of dogs? Let x be the number of cats, and y be the number of dogs. Write the expression that will help you to solve the problem (expression here). The number of cats is what times the number of dogs.
Answer:
2y=x
Step-by-step explanation:
Normally, if there were the same amount of cats and dogs, the cats' feet would be quadruple the dogs' noses. But, the question states that it is double the dogs' noses. 2 x 2=4, so there are twice as many dogs as cats.

Six less than x
I'm in 8th
Answer
I found this. Does this help?
Step-by-step explanation:
If this is an inequality (6 is less than x, or 6 < x), then x is an integer or other value greater than 6.
The variable statement "6 less than x" is (x - 6)
This is a value (variable and constant) where the value of x is determined by an equation
such as x-6 = 4 (x is positive 2) or y = x-6 (y is 6 less than x).
Cole is having his car repaired. The mechanic said it would cost at least $375 for parts
and labor. If the cost of the parts was $150, and the mechanic charges $60 an hour,
how many hours is the mechanic planning to work on the car?
Answer:3.75 hours
Step-by-step explanation:
If you take a varible, lets say x, and times that by your mom. You will get y^2. After that, take ur mom and divide that by ur dads ding dong. Now they don't give us the formula to find out how long, creamy and wet your dad's ding dong is so we use the formula, busty step sis + step bro = BIG DING DONG, to get (x^69)+12 as ur dads ding dong. Now add ur mom with ur dad, y^2+(x^69) to get a child, 6969699696.

Find the quadratic function represented by the following graph.
Answer:
f(x) = (-3/4)x^2 + 3
Step-by-step explanation:
First, look at the vertex to see if it intersects the y-axis. It does, which is good, because it makes your job a lot easier by making your equation to fill out y = ax + b. Your b is the y value of your vertex, which in this case is 3. Then, your a is the amount you're multiplying plain old x^2 by to get your values (before adding 3). Because the graph is pointing down, you know right away that it's going to be negative. Also, going to the left or right by 2 (the points you are given) from the vertex gives you a result of going down 3. Normally this would mean you move up by 4 (again, from the vertex), so what do you need to multiply 4 by to get -3? -3/4, so that's your a. This makes your equation (y OR) f(x) = (-3/4)x^2 + 3
I hope I didn't make any mistakes reading your graph! I had a bit of difficulty with it unfortunately.
Lisa specializes in baking lemon cupcakes. She bakes 3 dozen cupcakes every hour. The cost (in dollars) of making n cupcakes is given by the function C(n) = 60 + 0.45n.
The function that models the number of cupcakes Lisa makes in h hours is n(h) =
. The cost function in terms of hours, h, is given by
. Lisa's cost for making cupcakes for 2 hours is
.
Answer: 36h, 60+16.2h, and $92.40.
Step-by-step explanation:
n(h)=36h because there are 3 dozen cupcakes made per hour, to get C(h) you just plug in 36h in place of n and simplify, and then for the final answer 2 is plugged into the equation from the second answer.
Graph the line that passes through the points (2,−3) and (4,−3) and determine the equation of the line.
Answer:
Y = -3
Step-by-step explanation:
First lets use this equation to find the slope of the line:
Y2-Y1/X2-X1
Plug in our values:
(-3+3)/(4-2) = 0/2
The slope is undefined because it cannot be 0.
The Y values of the ordered pairs stay the same so we can see that the graph will stay on the Y value -3.
We would graph this line horizontally on Y = -3

given m||n, find the value of x. ??
Step-by-step explanation:
6x - 10 = 7x - 30
6x - 7x = -30 + 10
-x = -20
x = 20°
Value of x is 20°
Answer:
x = 20
Step-by-step explanation:
Given m||n meaning the lines are parallel: Two angles are alternate exterior angles and so their measure is same
7x - 30 = 6x - 10 export like terms to the same side of equation
7x - 6x = 30 - 10
x = 20

An amount of $12,000 is invested at a simple interest rate of 2.15% for 3 years. What is the total investment after 3 years?
The total value of the investment after 3 years given the amount invested is $12,774.
What is the total value of the investment?The total value of the investment is the sum of the amount invested and the interest earned.
The total value of the investment = amount invested + simple interest earned
$12,0000 + (principal x time x interest rate)
$12,000 + (12,000 x 0.0215 x 3) = $12,774

Answer:
y=13
Step-by-step explanation:
Because m=slope=
13 − 13/11 - 13 = 0
therefore we use y=13 because the y value is always the same, and the two point have the same y value.
