Answer:

equation is the best model of the data: y=0.5x+2.4

Step-by-step explanation:

y=2.8(1.1^x)

try two points (2,3.5) and(1,3)

find m=y2-y1/x2-x1

m=3-3.5/1-2=

m=0.5

find b at point 1,3

y=mx+b

3=0.5(1)+b

b=3-0.5

b=2.5

konstantin123 [22]

Answer: x = -17

Step-by-step explanation:

4x-13=5x+4

(4x-13)+(13-5x)=(5x+4)+(13-5x)

4x-13+13-5x=5x+4+13-5x

4x-5x-13+13=5x-5x+4+13

-x=17

joe scored less than four times the amount of baskets peter scored. How many did they each score if l together they scored 32 ba
slava [35]

Let us assume the amount of baskets Joe scored = x baskets.

4 times of x is 4x.

4x+x = 5x.

Therefore, Peter scored = 5x.

Together they scored = 32 baskets.

Sum of Peter score and Joe score = 32.

x+5x = 32.

6x = 32.

Dividing both sides by 6, we get

x = 32/6

= 16/3.

x= 16/3.

<h3>Joe scored = 16/3 baskets.</h3><h3>Peter scored = 5 × 16/3 = 80/3 baskets.</h3>

What’s five and one-half less than 3 times a number ?
notka56 [123]

The equation is 3n - 5 1/2. 5 1/2 = 5.5

3n - 5.5

n could equal 1 so, 3 x 1 - 5.5 = -2.5

3n - 5 1/2 = -2.5

Please help me with this I’m confused please explain
Maksim231197 [3]

Answer:

25. If you look at angle B from the first figure you see a square that indicates a 90 degrees angle, thus the figure shown is a right triangle. You can also see that angle C is said to have 60 degrees. a right triangle has a total angle of 180 degrees. so, 180 - 90 - 60 = 30 degrees. Therefore, angle A is 30 degrees.

27. Now you want the measure of the hypotenuse, and you know this a right triangle. so, simply use the law of sines to find the measure of AC :

4cm/sin(60) = AC/Sin90

AC = 4.62 cm

29. angle z is in the other figure and same stuff, just substract the angles, you have 90 degrees and 30 degrees... 180 - 90 - 30 = 60 degrees

31. Angle Y = 90 degrees

this value is already given, it's the little square that indicates a 90 degrees angle.

26. 5 cm

28. 90 degrees

30. You already found AC, use the pythagorean theorem. sqrt((4.62)^2 - 4^2) = 2.31 cm

32. use pythagoras again, square root(5^2 - 3^2) = 4

So as you can see all the measurements are the same because if you see at the very top of your figures it says ABC = XYZ which means pretty much that they have the same values (notice that there is a little something added to the = sign, watch out for that because that's what indicates that two figures are equal in terms of angles and measures.
