Answer:
4, -1
Step-by-step explanation:
We can let x and y represent the two numbers. The first relation is ...
2x + 4y = 4
The second relation is ...
x - y = 5
Subtracting the second relation from half the first gives ...
1/2(2x +4y) -(x -y) = 1/2(4) -(5)
3y = -3
y = -1
From the second relation, ...
x = 5 +y = 5 -1 = 4
The two numbers are 4 and -1.

Point P is located on the segment between point A (1,4) and point D (7,13). The distance from A to P is twice the distance from
Pto D. What are the coordinates of point P?
Answer: Point P is at (3, 7)
Step-by-step explanation: the distance from point a to point B is 10.8. 10.8 divided by 3 is 3.6, so you have to find a point that 3.6 from point a. Using a graph, I found the answer to be (3,7)
In a litter of 7 kittens, each kitten weighs less than 3.5 ounces. Find all of the possible values of the combined weights of the kittens.
3.4 x 7 = 23.8 ounces
3.3 x 7 = 23.1 ounces
3.2 x 7 = 22.4 ounces
3.1 x 7 = 21.7 ounces
3 x 7 = 21 ounces
and so on, use a calculator and go until hit 0.1 btw all these answers r written in bold. :)

Hello! answer: x = 94
Step-by-step explanation:
Triangles add up to 180 degrees so we just add up the two measures we do have so 48 + 38 = 86
Now we subtract that from 180 to find x so
180 - 86 = 94 So 94 is x Hope that helps!
You would burn about 200 calories by walking for 1 hour. About how many calories would you burn if you walk for 15 minutes? PLS HELP ME!!!
Answer:
50
Step-by-step explanation:
So first just sort the times, and the number of calories:
200 calories -> 1hr
x -> 15 mins
So an hour is 4 times the amount of 15 mins, so all you need to do is divide 200 by 4. The answer is 50

The width of a rectangle measures (4d – 8) centimeters, and its length measures
(7d – 3) centimeters. Which expression represents the perimeter, in centimeters, of
the rectangle?
Answer:
(22d-22) cm
Step-by-step explanation:
perimeter= 2×(4d-8+7d-3)
= 2× (11d-11)
(22d - 22) cm
Answer:
(22d-22)cm
Step-by-step explanation:
Perimeter = 2 x (width + Length)
= 2 x [(4d – 8) + (7d – 3)]
= 2 x (11d-11)
= (22d-22)cm

Which description best summarizes the correlation between the calls made and the texts sent
Mm
Answer:
Weak positive
Step-by-step explanation:
From. Visual inspection of the scatter plot, the line of best fit will have a positive slope has values of x tends to increase with a corresponding increase in the value of y.
However, the points are scattered across the plotting area meaning that most of the points will be a bit farther away from the regression line. This means a weak correlation between the x and y variables will be obtained. Since the slope is positive, theb the relationship between the variables based on the scatterplot interpretation is a weak positive correlation.

Answer:
Not gonna do the whole thing for you for 5 points
Step-by-step explanation:
The formula for Circumference is C = 2πr or C = dπ
r (radius) is the length of halfway across the circle
d (diameter) is the length across the whole circle (also it's equal to 2r)
You can solve it with that info
Don't forget to round if you need to
Which statement best describes the association between variable X and variable Y?
Answer:
weak, negative association
Step-by-step explanation:
If variables have a strong association, the points will form a clear line/curve. Since the graph's points are scattered and fairly chaotic, we can say the association is weak.
Positive associations trend upwards and negative associations tend downwards. This graph seems to overall tend downwards, so we can say the association is negative.
does anyone know the answer for this?
Answer:
8 cm
Step-by-step explanation:
The area of the shaded portion is:
[tex]a = \pi \times (( {r1)}^{2} - {(r2}^{2})) [/tex]
A=39π cm^2
r1 is the radius of the large circle
r2=5 cm
So,
[tex]39\pi = \pi \times (( {r1)}^{2} - {5}^{2} ) \\ r1 = 8 \: cm[/tex]
