Answer:
<h2>84°</h2>
Step-by-step explanation:
There are two properties we need to understand to solve this:
1. The angles of a triangle always add up to 180°
2. The angles along a straight line must add up to 180°
Let's solve!
Notice that the bottom angle is 134°, but we want to know the other angle. Since they add up to 180°` (because this is a straight line) we will subtract 134 from 180, to get an answer of 46°.
To solve the next angle we will do the same process:
180 - 130 = 50
50°
Now that we have two angles of the triangle, we can solve for x. Remember that the three angles of the triangle add to 180°.
Adding the two angles together:
50 + 46 = 96
And subtracting them from 180:
180 - 96 = 84
The value of x is 84°
I'm always happy to help :)
Answer:
-4 ≤ x ≤ -2, 4 ≤ x ≤ 7
Step-by-step explanation:
A function shows the relationship between two or more variables. A function is said to be constant over an interval if its output value is same for every input value within that interval.
As seen in the question, the x variable is the input while the y variable is the output. The function is constant from x = -4 to x = -2. Also, the function is constant within the interval from x = 4 to x = 7. Hence, the interval is:
-4 ≤ x ≤ -2, 4 ≤ x ≤ 7
Answer:
The answer is $8.13
Step-by-step explanation:
subtract $2.12 from $10.25
Since a pound of sugar increases proportionally to the total cost of sugar bought, then the function can be written as:
c(p) = 0.42p
Where: c(p) = total cost of sugar bought
p = pounds of sugar
c(p) is a function of p, because c(p) depends on p.
Ax²+bx+c
when a=1 then it is easy
find what 2 numbers myltiply to get c and add to get b
example, if they were d and e then it would factor to
(x+d)(x+e)
if it was -d and e then
(x-d)(x+e)
so
x²+8x+12
what 2 numbers multiply to get 12 and add to get 8?
6 and 2
(x+6)(x+2)
w²+2w-24
what 2 numbres multiply to -24 and add to 2?
-4 and 6
(w-4)(w+6)
x²-11x+24
what 2 numbers multiply to get 24 and add to get -11?
-3 and -8
(x-3)(x-8)
x²-5x-36
what 2 numbers multiply to get -36 and add to get -5?
-9 and 4
(x-9)(x+4)
