Answer:
(- 2, 0 )
Step-by-step explanation:
to find where the line crosses the x- axis, let y = 0 in the equation and solve for x.
0 = 3x + 6 ( subtract 6 from both sides )
- 6 = 3x ( divide both sides by 3 )
- 2 = x
the line crosses the x- axis at (- 2, 0 )
Instead of y write 0:
0=3x+6
Now all we have to do is solve for x :0=3x+6
Subtract 6 on both sides :
-6 = 3x
Switch the order :
3x = -6
Divide by 3 on both sides :
x = -2
Now that we know the x coordinate of the point, we should find the y coordinate, which is always equal to 0.
Coordinates of the point ↓(-2, 0)

A f(x) = x8
B f(x) = 8*
C f(x) = 64(2)*
D f(x) = 8x
Answer:
B. f(x) = 8*
Step-by-step explanation:
putting the value given in table

Line M is represented by the following equation: x - y = 8
Which equation completes the system that is satisfied by the solution (18, 10)? (4
points)
1) 2x - y = 26
2) x + y = 18
3) 2x - 2y = 36
04) x - y = -28
Answer:
1) 2x - y = 26.
Step-by-step explanation:
Solution = (18, 10)
2x - y = 26 fits the bill
as 2(18) - 10
= 36 - 10
= 26.
What is the range of the given function?
{(-2, 0), (-4, -3), (2, -9), (0, 5), (-5, 7)}
{x | x = -5, -4, -2, 0, 2}
{y l y = -9, -3, 0, 5, 7}
O (x | x = -9, -5, -4, -3, -2, 0, 2, 5, 7}
O tyl y = -9, -5, -4, -3, -2, 0, 2, 5, 7}
Answer:
{-9, -3, 0, 5, 7}
Step-by-step explanation:
Well, you already have the relation of the function. The domain of a function are its x coordinates and the range are all the y coordinates:
0, -3, -9, 5, 7
We write them in ascending order:
-9, -3, 0, 5, 7
And this way we get the range
It is important to check if the coordinates you are given can form a function. In this case they do, but in other cases they might not.
If you have coordinates where for example there are two equal values of x but the y is different in both, for example (1, 2) and (1, 5), this cannot be a function because y can be on two possible destinations for the same value of x.

Jerry hiked along a path. From his starting position, he hiked downhill to a valley where the elevation dropped 25 meters below his starting position. Then, he hiked up to a hill that was 40 meters higher than the valley.
The following equation describes this situation.
-25 + 40 = 15
CHOOSE 1 ANSWER
1. Jerry hiked a total of 15 meters
2. the hill was 15 meters higher than the elevation of his starting point
3. None of the above
Answer:
15 represents where Jerry is after the elevation dropped 25 meters and then rose 40 meters.
Step-by-step explanation:
It's given that Jerry hiked downhill to a valley where the elevation dropped 25 meters below his starting position. Then, he hiked up to a hill that was 40 meters higher than the valley
Hiked downhill = 25 meters
Hiked up = 40 meters
The given equation is
Here, hiked downhill represented by negative sign and hiked up resents by positive sign.
So, 15 represents that Jerry hiked up 15 meters from his starting position.
(2, the hill was 15 meters higher than the elevation of his starting point)
Answer:
2.
Step-by-step explanation:
The hill was -25 + 40 = 15 meters highe than starting point.

Two sides of a parallelogram are 170 feet and 650 feet. The measure of the angle between these sides is 113°. Find the area of the parallelogram to the nearest square foot.
The area of the parallelogram is equal to 101716 ft².
QuadrilateralsThere are different types of quadrilaterals, for example: square, rectangle, rhombus, trapezoid and parallelogram. Each type is defined accordingly to its length of sides and angles. For example, the opposite sides of a parallelogram are equal and parallel.
Parallelogram AreaYou can find the parallelogram area from two formulas:
A=b * h , where b=base and h=height;A= a*b* sin(Θ), where a=side 1, b=side 2 and Θ=angle between the sides;The question gives: the length of both sides (170 ft and 650 ft) of the parallelogram and the angle between these sides (113°).
Thus, you can apply the formula: A= a*b* sin(Θ). Therefore:
A= 170 * 650* sin (113°)
A=101716 ft²

Volume of a Cone Level 1
The volume of the cone is the amount of space in it
The volume of the cone is 264.3 cubic inches
How to determine the volume?The given parameters are:
Height, h = 9.9 inDiameter, d = 10.1 inThe volume of a cone is then calculated as:
V = 1/3π(d/2)²h
This gives:
V = 1/3 * 3/14 * (10.1/2)² * 9.9
Evaluate the product
V = 264.256905
Approximate
V = 264.3

Select all the expressions that are equivalent
Answer:
B, C, D
Step-by-step explanation:
One of the rules of exponents is that an exponent in the numerator is equivalent to the opposite of the same exponent in the denominator. That means ...
[tex]4^{-3}=\dfrac{1}{4^3}\qquad\text{matches C.}[/tex]
Another rule of exponents is that an exponent represents repeated multiplication. If a factor can be written using an exponent, the exponents are effectively multiplied.
[tex]4^{-3}=(2^2)^{-3}=2^{2(-3)}=2^{-6}\qquad\text{matches B.}[/tex]

A) A
B) B
C) C
D) D
Answer:
Answer is D
Step-by-step explanation:
Day 1 = 60
Day 2 = 120
Day 3 = 180
Day 4 = 240
Day 5 = 300
Day 6 = 360
Day 7 = 420
Day 8 = 480
The graph D will show the best relationship between the number of days and the number of frozen treats sold.
What is graph?In math, a graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.
It is given that he sells 60 frozen treats per day so everyday the frozen treats are multiplied by 60.
We can see the linear relationship between frozen treats and number of days.
Day 1 - 60
Day 2 - 120
Day 3- 180
Day 4- 240
Day 5- 300
Day 6- 360
Day 7- 420

What is the experimental probability of rolling a number less than 4?
A: 1/2
B: 16/33
C: 1/22 D: 17/33
what is the answer?
HELP
Answer:
A. 1/2
Step-by-step explanation:
For the question, it says what is the experimental probability of rolling a number less than 4, meaning it is asking for the experimental probability of rolling a 1, 2, or 3. Assuming this is a fair 6-sided dice, the probability of rolling any number is 1/6. The probability of rolling a 1, 2, or 3 is also 1/6. Adding all those the probabilities of 1, 2, and 3 together gets 3/6, which simplifies to 1/2.
Therefore, the experimental probability of rolling a number less than 4 is 1/2.
