A line passes through the points (–3, –4) and (6, 2)
What is the x-intercept of this line?
please help ahhh
Answers
9514 1404 393
Answer:
(3, 0)
Step-by-step explanation:
The line through these points intersects the x-axis at x=3.
The x-intercept is (3, 0).
_____
The x-intercept can be computed from ...
x-intercept = x1 -y1(x2 -x1)/(y2 -y1)
= -3 -(-4)(6-(-3))/(2-(-4)) = -3 +4(9/6) = -3 +6
x-intercept = 3
__
Here, it is simple enough to plot the points and see where the line crosses the x-axis.

A recipe says it produces the best sweet tea. In addition to using tea bags, the recipe calls for 1/2 cup of sugar for every 1 1/2 cups of water. Write an equation that shows the relationship between the number of cups of sugar to the number of cups of water in this recipe. Let x represent the number of cups of sugar and y represent the number of cups of water
Answers
Answer:
y = 3x
Step-by-step explanation:
In this case, the ratio between sugar and water is 0.5 : 1.5 or 1 : 3.
That means that you need three cups of water for every cup of sugar.
In order to put this into an equation, the slope would be 3/1 or simply 3, and the y-intercept is 0. Even if you used the 0.5 : 1.5 ratio, the slope would be the same since 1.5 / 0.5 = 3.

A flying disc in the shape of a circle has a circumference of 8 inches. What is the radius of the flying disc.
Answers
Answer:
A.
Step-by-step explanation:
Recall that circumference is given by:
[tex]C=2\pi r[/tex]
We know that the circumference is 8π inches. Thus, we can substitute 8π for C:
[tex]8\pi =2\pi r[/tex]
To solve for r, the radius, we can divide both sides by 2π. Hence:
[tex]\displaystyle r = \frac{8\pi}{2\pi}=4[/tex]
Therefore, the radius is four inches.
Our answer is A.
A random sample of hybrid vehicle fuel consumptions has a sample mean of x¯=53.2 mpg and sample standard deviation of s=4.8 mpg. Use the Empirical Rule to estimate the percentage of hybrid vehicle fuel consumptions that are less than 43.6 mpg. Round your answer to the nearest tenth.
Answers
Answer:
2.5%
Step-by-step explanation:
Since the mean is 53.2, a fuel consumption of 43.6 mpg is 53.2−43.6=9.6 mpg less than the mean, which is 2 standard deviations.
By the Empirical Rule, we know that about 95% of the data lies within 2 standard deviations of the mean. Therefore, 100%−95%=5% of the data lie more than 2 standard deviations away from the mean.
Since the distribution of hybrid vehicle fuel consumptions is symmetric, about half of the remaining 5% will lie to either extreme. So about 2.5% of fuel consumptions are less than 43.6 mpg.
The normal distribution is a symmetric probability distribution about the mean. The percentage of hybrid vehicle fuel consumption that is less than 43.6 mpg is 2.5%.
What is Normal Distribution?The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data distant from the mean. The normal distribution will show as a bell curve on a graph.
Given that the mean is 53.2, while the standard deviation is 4.8 mpg. Therefore, Accoding to the emperical rule, we can write the values as,
μ+3σ = 67.6
μ+2σ = 62.8
μ+σ = 58
μ = 53.2
μ-σ = 48.4
μ-2σ = 43.6
μ-3σ = 38.8
Therefore, The percentage of hybrid vehicle fuel consumption that is less than 43.6 mpg is,
Percentage = (0.15 + 2.35)% = 2.5%
Hence, The percentage of hybrid vehicle fuel consumption that is less than 43.6 mpg is 2.5%.

Step-by-step explanation:
If the original image is Q ( -7, -6 ) and you are looking for Q' ( A translated version of the original image )
If the translation is ( x, y ) --> ( x + 12, y + 8 )
If coordinates are ( x , y ) and the original image is ( - 7, -6 )
Then that means:
x = -7
y = -6
Use the original coordinates you have and add them with the translation given to you

Step-by-step explanation:
Divide 3 by 15 to get 1/5. If you divide 1 by 5, you will get a decimal answer of 0.2. To convert a decimal to a percent, you must multiply the decimal by 100, which basically means to move the decimal place to the right twice. You will then get the product and final answer of 20%.

Find the dimensions of the rectangle of largest area that has its base on the x-axis and its other two vertices above the x-axis and lying on the parabola. (Round your answers to the nearest hundredth.)
Answers
Complete question is;
Find the dimensions of the rectangle of largest area that has its base on the x-axis and its other two vertices above the x-axis and lying on the parabola. (Round your answers to the nearest hundredth.) y = 6 - x²
Answer:
height = 4 and base = 2√2
Step-by-step explanation:
Area of a rectangle is given by;
A = base(b) × height(h)
To start off, we will first have to consider half of the rectangle.
Due to the fact that it is bounded by a parabola which is symmetric over the y-axis, it means that the rectangle will have the same area on the right and left hand sides.
So if we maximize the area of the first quadrant, it means that we are also maximizing the area of the entire rectangle.
Now, since we are dealing with the base and other 2 vertices on the x-axis, it means that the base(b) of this half rectangle will be x.
The height of this rectangle is the y coordinate of the corner that is directly above the x coordinate, which is also on the rectangle.
Therefore, the coordinates of the upper corner will be (x, y), or (x, 6 - x²). Thus our half base is x and full height is 6 - x². Area will be;
A = x(6 - x²)
A = 6x - x³
We will maximize this area by finding the derivative and equating to zero.
Thus;
A' = 6 - 3x²
At A' = 0,we have;
6 - 3x² = 0
3x² = 6
x² = 6/3
x² = 2
x = √2
Thus, from y = 6 - x², we have;
y = 6 - (√2)²
y = 6 - 2
y = 4
Since x is half base, it means our full width is 2x = 2 × √2 = 2√2
So, height = 4 and base = 2√2

Charlie knows that 3 blocks are needed to make a tower that is 0.5 foot high.
How many blocks will be needed to make a tower that is 4 feet high?
Answers
Answer:
24 blocks will be needed to make the tower that is 4 feet high
Step-by-step explanation:
Let us use the ratio method to solve the question
∵ Charlie knows that 3 blocks are needed to make a tower that is
0.5 foot high
∵ He needs to make a tower that is 4 feet high
→ By using the ratio method
→ Blocks : height (ft)
→ 3 : 0.5
→ x : 4
→ By using the cross multiplication
∵ x × 0.5 = 3 × 4
∴ 0.5x = 12
→ Divide both sides by 0.5 to find x
∵ [tex]\frac{0.5x}{0.5}[/tex] = [tex]\frac{12}{0.5}[/tex]
∴ x = 24
∵ x represents the number of blocks
∴ 24 blocks will be needed to make the tower that is 4 feet high
