Answer:
4a) $26.5 because if x represents how many feet then the slope would be the price of one glulam beam.
4b) $63,600
Step-by-step explanation:
To find the answer to 4b we need to alter the equation we were given. Since x represents how many feet we buy we put 2400 in place of x.
y = 26.5 x 2,400
and we simply solve from here
y = 63,600
So, 63,600 is how much we would be spending for 2400 feet of beams. Hope this helps!!

The hcf of 182 and x is 26 and the l.c.m of 182 and x is 1092 determine the value of x
Answers
The value of x such that the hcf is 26 and the l.c.m is 1092 is 156
How to determine the value of x?The numbers are given as:
182 and x
The HCF and LCM are given as:
HCF = 26
LCM = 1092
As a general rule;
The product of LCM and HCF of x and y equals the product of x and y
So, we have:
182 * x = 26 * 1092
Divide both sides by 182
x = 156
Hence, the value of x is 156

In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.From the table, we have that:

Guys, I beg you! How do you do these factoring quadratic equations!
Which is a solution to (x − 2)(x + 10) = 13
Answers
======================================================
Explanation:
There are at least three ways to solve this.
----------------------------------------------
Method 1:
We could graph y = (x-2)(x+10) using a tool like Desmos. Graph y = 13 as well which is a horizontal line.
Check out the screenshot shown below.
The parabola in red and the horizontal line in blue intersect at the locations (-11, 13) and (3, 13)
We only focus on the x coordinates of the intersection points.
Therefore, the two solutions are x = -11 and x = 3
The order of the solutions doesn't matter.
----------------------------------------------
Method 2:
Expand things out and get everything to one side
(x-2)(x+10) = 13
x^2 + 10x - 2x - 20 = 13
x^2 + 8x - 20 - 13 = 0
x^2 + 8x - 33 = 0
From here we can use the quadratic formula
[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-8\pm\sqrt{(8)^2-4(1)(-33)}}{2(1)}\\\\x = \frac{-8\pm\sqrt{64+132}}{2}\\\\x = \frac{-8\pm\sqrt{196}}{2}\\\\x = \frac{-8\pm14}{2}\\\\x = \frac{-8+14}{2} \ \text{ or } \ x = \frac{-8-14}{2}\\\\x = \frac{6}{2} \ \text{ or } \ x = \frac{-22}{2}\\\\x = 3 \ \text{ or } \ x = -11\\\\[/tex]
----------------------------------------------
Method 3:
Instead of using the quadratic formula, we could factor.
To factor x^2+8x-33, we need to find two numbers that
Multiply to -33Add to 8Through trial and error, you should get 11 and -3
11 times -3 = -3311 plus -3 = 8So,
x^2+8x-33 = 0
(x+11)(x-3) = 0
x+11 = 0 or x-3 = 0
x = -11 or x = 3
A cube has a surface area of 181.5sq. In. What is the length of the sides
Answers
Answer:
Answer = 5.5
Step-by-step explanation:
The formula for finding the surface area of a cube is SA = 6(s^2) where s = sides. Since we know the surface area we plug it in for SA. So,
181.5 = 6*s^2
Now we divide 6 by both sides to get
30.25 = s^2
Now we have to find the square root of both sides to get
5.5 = s

C There were 56 more people who ate a turkey sandwich than ate a chicken sandwich. с D There were 28 more people who ate a salad than ate a chicken sandwich.
Answers
Using proportions, it is found that the correct statement is given by:
C There were 56 more people who ate a turkey sandwich than ate a chicken sandwich.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, one third out of 840 people ate Turkey Sandwich, hence the number is given by:
nT = 840/3 = 280.
One sixth ate Vegetarian Sandwich, hence the number is given by:
nV = 840/6 = 140.
4/15 ate Chicken Sandwich, hence the number is given by:
nC = 4 x 840/15 = 224.
7/30 ate Salad, hence the number is given by:
nS = 7 x 840/30 = 196.

OD.
Each equation represents a line that increases from left to right.
Answers
Answer:
A. Yes they do. Both equations have their opposing set of y-intercept. Where equation one has a y-intercept of +7, and equation two, +7.
B. No they do not. Equation one has a slope of +3, while equation 2 has a slope of -4.
C. Yes they do. Equation one represents that of a positive increasing graph, while equation two the opposite, decreasing.
Step-by-step explanation:
You can use the slope formula to identify and graph each equation simply by using y = mx + b. Where y is the the y coordinate, x is the x coordinate, m is the slope, and b is the y-intercept. With this you can start plotting by marking the y-intercept by putting the x as zero and seeing what number you get. In this case, 3x0-7 = -7. Meaning that would be the y-intercept. For the slope, depending on what the x coordinate is, that's how much the graph will increase or decrease whenever the x coordinate changes. Say the x coordinate is 1, so 3x1-7 = 3-7 = -4. Meaning your coordinate would be (1, -4) where you can keep doing this formula on and on to find the y coordinate for what x coordinate you want to find, or make it easier to graph with a ruler on paper once you have enough points.
