Answer:
(x-3)(x+5) = 0
x-3 = 0 and x+5=0
x=3 and x=-5 when y=0
y = x^2+2x-15
complete the square
= x^2+2x + 1 -15 - 1
= (x+1)^2 -16
f(x) = y = (x+1)^2 -16
y intercept = -15 or the point (0,-15)
x intercepts = 3 and -5 = the two zeroes or roots, or the points (3,0) and (-5,0)
vertex or minimum point of the upward opening parabola is (-1,-16)
note the 2 zeroes are both 4 units horizontally from the vertex x value, 3 to -1 is 4, and -1 to -5 is 4.
the line of symmetry is x=-1. left and right of x=-1 are mirror images

Determine the mystery decimal number from the clues listed.
Clue 1: between 2/5 and 3/5
Clue 2: greater than 1/2
Clue 3: a multiple of 0.11
Answer:
.55
Step-by-step explanation:
3/5 = 0.6
1/2 = 0.5
it has to be in between these two numbers
5 x 0.11 = 0.55
Answer:
Step-by-step explanation:
It is between 0.4 and 0.6
It is greater than 1/2. That means that the starting point is 0.5 to 0.6
The final clue should nail it. It is a multiple of 0.11. That means it is 0.55. One possible answer is 11/20

Step-by-step explanation:
If everything is kept in terms of x then:
For part A the general area would just be side times side.
Here it would be (30x)(4x)
=[tex]120x^{2}[/tex]
For part B since you have 5 sections divide the long side by 5.
[tex]\frac{30x}{5} =6x[/tex]
Then multiply by the other side of the rectangle to find the area of one section.
6x(4x)=[tex]24x^{2}[/tex]
Alternatively you could just divide the large area by 5 to get the area of one section.
[tex]\frac{120x^{2} }{5}=24x^{2}[/tex]

Find the difference (7-3t) - 5(-1.6t + 5)
Answer:
5t - 18
Step-by-step explanation:
STEP 1: Simplify 8/5
equation at end- 8 (7 - 3t) - (5 • ((0 - (— • t)) + 5)) 5
STEP 2: 2.1 Adding a whole to a fraction
Rewrite the whole as a fraction using 5 as the denominator :
5 5 • 5
5 = — = —————
1 5
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
\2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
-8t + 5 • 5 25 - 8t
——————————— = ———————
EQUATION AT END: (25 - 8t)
(7 - 3t) - (5 • —————————)
5
STEP 3: (7 - 3t) - (25 - 8t)

60 °
Answer:
[tex]\bf{50 \degree }[/tex]
Step-by-step explanation:
Given:
[tex]\begin{aligned}&\sf \triangle \ ABC \\&\sf \angle B \ \cong \angle C \end{aligned} [/tex]
Solve for x
[tex]\begin{aligned}&\sf 5x-10=4x+5 \\&\sf 5x-4x=5+10 \\&\sf x=15 \end{aligned} [/tex]

[tex]\begin{aligned}&\sf (5x-10)\degree \\=&\sf \ (5(15)-10)\degree \\=&\sf \ (75-10)\degree \\=&\sf \ 65 \degree \end{aligned} [/tex]
Solve for m
[tex]\begin{aligned}&\sf m=180 \degree -(\angle B + \angle C) \\&\sf m=180 \degree -(65 \degree + 65 \degree ) \\&\sf m=180 \degree - 130 \degree \\&\boxed{\bf{m=50 \degree }} \end{aligned} [/tex]
Autumn takes 39 minutes to walk to work.
After getting a new job, the time it takes
Autumn to walk to work has decreased by
35%. How many minutes does it take
Autumn to walk to work now?
We are required to calculate how many minutes does it take Autumn to walk to work now
The number of minutes does it take Autumn to walk to work now is 25.35 minutes
Time taken to walk to work = 39 minutes
Percentage decrease = 35%
Decrease in time = 35% of 39 minutes
= 35/100 × 39 minutes
= 0.35 × 39 minutes
= 13.65 minutes
Number of minutes does it take Autumn to walk to work now
= 39 minutes - 13.65 minutes
= 25.35 minutes
Therefore, the number of minutes does it take Autumn to walk to work now is 25.35 minutes

At midnight, the temperature was 31.2 degrees above 0, and in the morning, it was 6.7 degrees lower.
At midnight, the temperature was 31.2 degrees below 0, and in the morning, it was 6.7 degrees higher.
At midnight, the temperature was 31.2 degrees above 0, and in the morning, it was 6.7 degrees below 0.
At midnight, the temperature was 31.2 degrees below 0, and in the morning, it was 6.7 degrees above 0.
Answer:

Describe what is meant by the slope of a non-vertical line. Explain how your description relates to the definition of slope.
Answer: A verticle line does not have a slope.
Step-by-step explanation: Slope is the rate of change of y for each change in x. y = 2x is a line with slope of 2. Each time x is incremented by 1, y will increase by twice (2x) that amount. There is no slope to a verticle line, unless you want to call it infinite. The value of y is not defined by x.

d=2r show all steps pls
Answer:
Step-by-step explanation:
1.1 Solve d-2r = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line d-2r = 0 and calculate its properties
