Answer:
Step-by-step explanation:
1) 5xy - xy + 2x - 13x + 10xy - 8x = 5xy - xy + 10xy +2x - 13x - 8x
Combine like terms
= (5 -1 +10)xy + (2-13-8)x
= 14xy + (-19x)
= 14xy - 19x
2) -6c - (-6c) - (+6c) = -6c + 6c - 6c
= (- 6 + 6 - 6)c
= -6c
3) 0x - 22x - 4(2x) = 0x - 22x - 8x = -30x
If the discriminant is zero how many solutions are there:.

6x – 5 > -29
A:x > -4.
B: x <-4
C: x > 4
D: x < 4
Answer:
A
Step-by-step explanation:
6x - 5 > - 29 ( add 5 to both sides )
6x > - 24 ( divide both sides by 6 )
x > - 4 → A
We are given with a inequality and we have to find the solution for it . So , let's start :
[tex]{:\implies \quad \sf 6x-5\> -29}[/tex]
Adding 5 to both sides :
[tex]{:\implies \quad \sf 6x-\cancel{5}+\cancel{5}\>-29+5}[/tex]
[tex]{:\implies \quad \sf 6x\> -24}[/tex]
Dividing both sides by 6 ;
[tex]{:\implies \quad \sf \dfrac{\cancel{6}\cdot x}{\cancel{6}}\> -\dfrac{24}{6}}[/tex]
[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{x \> -4}}}[/tex]
Hence , Option A) x > - 4 is correct :D
Note :-Whenever dividing or multiplying an inequality by a -ve , so we have to tilt the sign too , while if we are multiplying or dividing with a +ve , so sign will remain the same , For example like if we are given with x > y , and we multiply both sides by -1 . So , it will then become - x < - y

Answer:
y = -3x + 2
Step-by-step explanation:
First we find the slope:
(11 - (-4)) / (-3 - 2) = 15/-5 or -3
Now we use this formula and solve for y to get slope-intercept form
y - y1 = m(x - x1)
y - (-4) = -3(x - 2)
y + 4 = -3x + 6
y = -3x + 2

small rectangle represent? Explain your
reasoning.
v
Answer:
1. 1/4
2. 1/2
Step-by-step explanation:
1. Without measuring I can't be 100% sure, but it looks like the smaller rectangle is 1/4 of the big rectangle, as the side lengths of the smaller rectangle are half those of the big rectangle.
2. If he delivered 3/8 of his newspapers in the first hour, then he had:

find area of shaded regions
Answer:
140.8584073
Step-by-step explanation:
Find the area of the shaded region by subtracting the area of the small shape from the area of the larger shape. The result is the area of only the shaded region, instead of the entire large shape. In this example, the area of the circle is subtracted from the area of the larger rectangle.

In the diagram below, FG is parallel to CD. If the length of C D is the same as the
length of FE, CE = 17, and FG = 6, find the length of FE. Figures are not
necessarily drawn to scale. State your answer in simplest radical
Answer: sqrt(102)
Step-by-step explanation:
We know that triangles GFE and DCE are similar by AA.
If we let CD=FE=x, then we can set up a proportion. Namely,
CE/FE = CD/FG
17/x = x/6
x^2 = 102 -> x=sqrt(102)

The general equation for depreciation is given by y = A(1 – r)t, where y = current value, A = original cost, r = rate of depreciation, and t = time, in years. A car was purchased 6 years ago for $25,000. If the annual depreciation rate is 11%, which equation can be used to determine the approximate current value of the car?.
The equation which is used to determine the approximate current value of the car by the depreciation equation is,
[tex]y=25000(0.89)^6[/tex]
What is depreciation?Depreciation is to decrease in the value of a product in a period of time. This can be given as,
[tex]y=A\left(1-{r}\right)^t[/tex]
Here,(y) is the current value, (A) is the original cost of the product, (r) is the rate of depreciation and (t) is the number of years.
Now the car was purchased 6 years ago. The original cost of the car is $25,000 and the annual depreciation rate is 11%.
The rate can be given as,
[tex]r=\dfrac{11}{100}\\r=0.11[/tex]
Thus, to find the equation can be used to determine the approximate current value of the car, put the values in the above formula as,
[tex]y=(25000)\left(1-{0.11}\right)^6\\y=25000(0.89)^6[/tex]
Hence, the equation which is used to determine the approximate current value of the car by the depreciation equation is,
[tex]y=25000(0.89)^6[/tex]

What is the solution to this equation?
−4(2m − 7) = 3(52 − 4m)
Answer:
m = 32
Step-by-step explanation:
-4(2m-7) = 3(52 - 4m)
-8m + 28 = 156 - 12m
-8m + 12m = 156 - 28
4m = 128
m = 32 Ans...
The required solution is m = 32 to the given equation −4(2m − 7) = 3(52 − 4m).
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
We have been given an equation as
⇒ -4(2m-7) = 3(52 - 4m)
Apply the distributive of multiplication,
⇒ -8m + 28 = 156 - 12m
Rearrange the terms of m in the above equation,
⇒ -8m + 12m = 156 - 28
Apply the subtraction operation,
⇒ 4m = 128
Divided by 4 both sides of the equation, we get
⇒ m = 32
Therefore, the solution is m = 32 to the given equation −4(2m − 7) = 3(52 − 4m).

The algebraic expression 3r+2p represents the total amount of money Sophia will spend on flowers if she buys any number of roses and tulips.
Sophia will spend a total of $29 on flowers if she buys 7 roses and 4 tulips.
======================================================
Explanation:
r = number of roses
p = number of tulips
3r = cost of all the roses only ($3 each)
2p = cost of all the tulips only ($2 each)
3r+2p = total cost of all the flowers mentioned, both types
----------------------
To find the total cost Sophia spends on 7 roses and 4 tulips, we plug in r = 7 and p = 4.
3r+2p = 3*7+2*4 = 21+8 = 29
Sophia would spend $29 if she bought 7 roses and 4 tulips.
The 3*7 = 21 part is the cost for the roses only.
The 2*4 = 8 part is the cost of the tulips only
The sum of which is the total cost for both types of flowers.

I found the answer by entering it into Desmos Graphing Calculator and then looking at the point of the vertex, which in this case would be (9,-3).
You could also find the x-intercepts, (p,0) and (q,0), using the quadratic formula and then plug them into the equation: x=p+q/2 which will give you your axis of symmetry, or your x value in your vertex. Then, plug that number into your equation. You can plug it into the equation you posted here or the equation of your x-intercepts. (x-p) (x-q) Keep in mind that the minus refers to you putting the opposite of your x-intercept. For example, if your x-intercept was 4, then you would have -4 in the equation.
