Which statement best describes the graph
The first option
you read the graph from left to right so x is increasing. If you look at y, it's decreasing.
for each y-value that decreases by 0.5, x-values increase by 1
The first option is correct, As the x- value increases by 1, the y-value decreases by 1/2; the x-intercept is -1.
What is a function?A function is defined as a relation between the set of inputs having exactly one output each.
we can from the graph from left to right is that x is increasing. If you look at y, it's decreasing.
And for each y-value that decreases by 0.5, x-values increase by 1.
Thus, As the x- value increases by 1, the y-value decreases by 1/2 ; the x-intercept is -1.

Here is an identity.
a(4x – 10) = 24x + 5b
Work out the values of a and b
Answer:
The value of a is 6 and the value of b is -12
Step-by-step explanation:
Given identity is:
a(4x – 10) = 24x + 5b
We can use the comparison of coefficients method to find the values of a and b
So,
By simplifying the left hand side of identity
[tex]4ax-10a = 24x+5b\\4ax+(-10)a = 24x+5b[/tex]
Comparing the co-efficient of x
[tex]4a = 24\\a = \frac{24}{4}\\a = 6[/tex]
Comparing the constant terms
[tex]-10a = 5b[/tex]
Putting the value of a
[tex]-10(6) = 5b\\-60 = 5b\\b = \frac{-60}{5}\\b = -12[/tex]
Hence,
The value of a is 6 and the value of b is -12
-2/9 - (-1/3 divided 3/5)
PLEASE HURRYY
Answer:
1/3
Step-by-step explanation:
-1/3 divided by 3/5 = -5/9
-2/9 - -5/9 = 1/3
Answer:
-1/45
Step-by-step explanation:
Rewrite this as:
-2/9 - (-1/5), or -2/9 + 1/5
Here the LCD is (9)(5) = 45. Rewriting the above expression, we get:
-10/45 + 9/45 = -1/45

The volume of a rectangular box is 1600 cubic inches. The height of the box is 8 inches and the length of the box is 2 times longer than the width of the box. What is the width of the box "IN FEET FT"?
Answer:
0.833 feets
Step-by-step explanation:
Given that:
Volume of box = 1600
Heigh of box (H) = 8 inches
Let:
Width of box (W) = x
Length of box (L) = 2x
Volume of box = (Height * width * length)
1600 = (8 * x * 2x)
1600 = 16x²
x² = 1600/16
x² = 100
x = sqrt(100)
x = 10 inches
Hence, width of box in feet:
1 inch = 0.0833 feets
10 inches = (10 * 0.0833) feets
= 0.833 feets

Find the value of p and q such that
2x^2 - 4x + 3= 2 (x-p)^2 + q
PLEASE ANSWER!!!
Answer:
The values of p and q such that 2·x² - 4·x + 3 = 2·(x - p)² + q, are;
p = 1, q = 1
Step-by-step explanation:
The given equation are;
2·x² - 4·x + 3 = 2·(x - p)² + q
By expanding the right hand side of the equation, we have;
2·x² - 4·x + 3 = 2·(x - p)² + q = 2·x² - 4·p·x + 2·p² + q
2·x² - 4·x + 3 = 2·x² - 4·p·x + 2·p² + q
Comparing the coefficient of x in both equations, gives;
2·x² + (- 4)·x + 3 = 2·x² + (- 4·p)·x + 2·p² + q
-4 = -4·p
∴ p = -4/(-4) = 1
p = 1
Comparing only the constant terms (terms not multiplied by "x" or "x²"), we get;
3 = 2·p² + q
Substituting the value for "p" obtained above (p = 1 ) in the previous equation, we get;
3 = 2 × 1² + q = 2 + q
∴ q = 3 - 2 = 1
q = 1.

What is the value of the expression? 9 3/4−2 1/5+1/2
_ -- > Ex: 9 1/7
I need this fast!
Answer: 8 1/20 or 8.05.
Step-by-step explanation: First you would want to make 9 3/4 - 2 1/5 to 39/4 - 11/5. We need to get the LCD or Least Common denominator of 4 and 5, which is 20. The rule is what you multiplied the denominator by you must multiply the numerator by, so our new equation is 195/20 - 44/20, which is 151/20. Now, we have to find the LCD of 2 and 20, which is 10. So 151/20 + 10/20 is 161/20 or 8 1/20.
