What is the slope of the line shown below? • (3,9) O A. -3 ch (1,3) O B. -6 O c. 6 O D. 3 # SUBM
The slope of the line with the coordinate points (-3, 9) and (1, 3) is -1.5.
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The formula to find the slope of a line is slope = (y₂-y₁)/(x₂-x₁).
The given coordinate points are (-3, 9) and (1, 3).
Substitute, (x₁, y₁)=(-3, 9) and (x₂, y₂)=(1, 3) in the slope formula, we get
Slope = (3-9)/(1-(-3))
= -6/4
= -3/2
= -1.5
Therefore, the slope is -1.5.

Answer: 8x+7
Step-by-step explanation:
The first thing you need to do is multiply (x+1) by 7 (this is the part where you use the distributive property). x times 7 is 7x and 1 times 7 is 7. So now you should have x+7x+7. Now just combine like terms. You can add x and 7x but you can't add the one because there is no variable (x) in it. Your final answer should be 8x+7. Hope this helps!

plz help
Answer:
5x+32y+76
Step-by-step explanation:
First, distribute.
4 x 2x = 8x
4 x 8y = 32y
4 x 9 = 36
Then, combine like terms.
8x - 3x = 5x
36 + 40 = 76

Charmaine drives a truck for a soft drink company. Her truck is filled with 20 ounce cans and 80 ounce bottles. Let x be the number of 20 ounce cans the truck is carrying, and let y be the number of 80 ounce bottles.The truck must be carrying at most 48,000ounce). Using the values and variables given, write an inequality describing this
9514 1404 393
Answer:
20x +80y ≤ 48000
Step-by-step explanation:
If x is the number of 20-ounce cans, then the number of ounces in the cans is 20x.
If y is the number of 80-ounce bottles, then the number of ounces in the bottles is 80y.
"At most 48,000 ounces" means the total of ounces of cans and ounces of bottles must be less than or equal to 48000.
20x +80y ≤ 48000

A marathon race participant walks at a rate of 2.5 miles per hour and runs at a rate of 5 miles per hour. The combined distance that the marathon race participant walks and runs is 12.5 miles. Write a linear equation in standard form that models this situation.
Answer:
2.5x + 5y = 12.5
Step-by-step explanation:
The solution is 2.5x + 5y = 12.5
The equation representing the total distance by the participant who runs and walks is given by 2.5x + 5y = 12.5 where x is the time required to walk and y is the time required to run
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is given by
The total distance ran by the marathon participant = 12.5 miles
Let the time taken by the participant to walk be = x
Let the time taken by the participant to run be = y
Now , the speed of the participant when walking = 2.5 miles per hour
The speed of the participant when running = 5 miles per hour
So , the equation will be
The distance traveled when walking = speed of the participant when walking x time taken by the participant to walk
Substituting the values in the equation , we get
The distance traveled when walking = 2.5x
And ,
The distance traveled when running = speed of the participant when running x time taken by the participant to run
Substituting the values in the equation , we get
The distance traveled when running = 5y
Now ,
The total distance ran by the marathon participant = The distance traveled when walking + The distance traveled when running
Substituting the values in the equation , we get
2.5x + 5y = 12.5
Therefore , the equation will be 2.5x + 5y = 12.5
Hence , the equation is 2.5x + 5y = 12.5 where x is the time required to walk and y is the time required to run

According to a posting on a website subsequent to the death of a child who bit into a peanut, a certain study found that 4% of children younger than 18 in the United States have at least one food allergy. Among those with food allergies, about 43% had a history of severe reaction. (a) If a child younger than 18 is randomly selected, what is the probability that he or she has at least one food allergy and a history of severe reaction
Answer:
0.0172 = 1.72% probability that he or she has at least one food allergy and a history of severe reaction
Step-by-step explanation:
We are given these following probabilities:
4% probability of that a child younger than 18 in the United States has at least one food allergy.
If a child has at least one food allergy, 43% probability of having a history of severe reaction.
If a child younger than 18 is randomly selected, what is the probability that he or she has at least one food allergy and a history of severe reaction
The multiplication of the probabilities. So
0.04*0.43 = 0.0172
0.0172 = 1.72% probability that he or she has at least one food allergy and a history of severe reaction

In a right triangle, the hypotenuse has endpoints XY, shown on the graph.

If Z represents the third vertex in the triangle and is located in the second quadrant with integer coordinates, what is the length of YZ?

9514 1404 393
Answer:
5
Step-by-step explanation:
A graph can be helpful. It shows possible integer coordinates of Z could be ...
(-1, 2) or (-5, 1)
These have distances 5 and 4√2 from Y, respectively. Of these, only the length YZ = 5 appears on your list of possible answers.
__
The hypotenuse of a right triangle is the diameter of the circumcircle. That is, the right angle vertex (Z) appears on a circle whose center is the midpoint of the hypotenuse. Here, that circle center is C = (-4-1, 2-3)/2 = (-5/2, -1/2). The given point Y differs from this by C - Y = (-5/2 -(-1), -1/2 -(-3)) = (-3/2, 5/2). So, a point with integer coordinates will be 2×(5/2) = 5 units above point Y, which puts it in the 2nd quadrant.
__
Adding any of the 8 combinations (±3/2, ±5/2) or (±5/2, ±3/2) to the circle center coordinates will result in integer coordinates for the right angle vertex. Of these, only the ones listed above are in the second quadrant. A couple are on the y-axis, and two of the possibilities are X and Y. The other two are in the third quadrant.
