Josh bought 3 bags of potting soil and 10 bags of mulch from Home Depot.
a) Write an equation torepresent the total cost.
Answers
Answer:
3x+10y=C
x=cost of potting soil
y=cost of mulch
C=total cost
An equation which represent the total cost will be,
⇒ 3P + 10M = C
Where, P is cost of potting soil bags.
M is cost of Mulch bags.
C is total cost.
What is an expression?
Expression in math is defined as the collection of the numbers, variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that;
Josh bought 3 bags of potting soil and 10 bags of mulch from Home Depot.
Now,
Let cost of potting soil bags = P
Cost of Mulch bags = M
Total cost = C
Then, An equation to represent total cost is;
3P + 10M = C
Thus, An equation which represent the total cost will be,
⇒ 3P + 10M = C
Where, P is cost of potting soil bags.
M is cost of Mulch bags.
C is total cost.

(I cannot see the x amounts to see if the units match, if the units are not moving up by 1 on the c axis the slope will be considered wrong)
Why?
Y=mx+b
M=slope
B= y intercept
Slope= rise/run
I moved up from point that directly intersects a point on the graph and moved up 3 and to the right 4 to another point that directly intersects a point.
To find the y intercept I can see that it will directly pass through 30 on the y axis so that is the y intercept
Hope this helps (if I need to explain better or if the x axis doesn’t move by 1s and I need to redo the slope just say something in the comments)

You cannot prove what isn't true.
We know you know how to use parentheses, so we take the left-side expression at face value. The left-side and right-side functions are different, so cannot be proved to be the same, except at specific angles.
Find the midpoint of the interval [-3, 6] along the number line.
Answers
Answer:
1.5 or 3/2
Step-by-step explanation:
The midpoint of the interval [-3, 6] along the number line is 1.5.
The midpoint of an interval is the point that lies exactly in the middle of the two endpoints.
To find the midpoint of the interval [-3, 6], we use the midpoint formula:
Midpoint = (Endpoint1 + Endpoint2) / 2
In this case, Endpoint1 is -3, and Endpoint2 is 6:
Midpoint = (-3 + 6) / 2
Midpoint = 3 / 2
Midpoint = 1.5
The midpoint of the interval [-3, 6] is 3/2. This means that the point exactly halfway between -3 and 6 on the number line is 1.5 units to the right of -3 and 1.5 units to the left of 6.
Visually, if you plot -3 and 6 on a number line, the midpoint 3/2 (or 1.5) would be located at the center, equidistant from both endpoints.

One number is 6 less than 5 times the other number. Their sum is 60. Find the numbers.
Answers
Answer:
The numbers are 11 and 49.
Step-by-step explanation:
x = 5y - 6 This is just the first sentence written as an equation.
x + y = 60 This is just the second sentence written as an equation.
5y - 6 + y = 60 Substitute x for what you know it is equal to
6y - 6 = 60 Collect like terms
6y = 66 Add 6 to each side
y = 11 Divide each side by 6
x = 5 × 11 - 6 Substitute y for what you know it is
x = 55 - 6 Simplify by working out 5 × 11 = 55
x = 49 Subtract 6 from 55 to get 49

If using the method of completing the square to solve the quadratic equation
x²-10x – 15 = 0, which number would have to be added to "complete the
square"?
Answers
Answer:
For quadratic equations that cannot be solved by factorising, we use a method which can solve ALL quadratic equations called completing the square. We use this later when studying circles in plane analytic geometry.
Completing the square comes from considering the special formulas that we met in Square of a sum and square of a difference earlier:
(x + y)2 = x2 + 2xy + y2 (Square of a sum)
(x − y)2 = x2 − 2xy + y2 (Square of a difference)
To find the roots of a quadratic equation in the form:
\displaystyle{a}{x}^{2}+{b}{x}+{c}={0}ax
2
+bx+c=0,
follow these steps:
(i) If a does not equal \displaystyle{1}1, divide each side by a (so that the coefficient of the x2 is \displaystyle{1}1).
(ii) Rewrite the equation with the constant term on the right side.
(iii) Complete the square by adding the square of one-half of the coefficient of x to both sides.
(iv) Write the left side as a square and simplify the right side.
(v) Equate and solve.
Example 1
Find the roots of x2 + 10x − 4 = 0 using completing the square method.
