Slope-Intercept Form: y = mx+b, with m = slope/rate of change and b = y-intercept.

So for this to be slope-intercept form, we first have to divide both sides by 2: $y=\frac{5}{2}x+5$

Now that it's slope-intercept form, we see that the rate of change is 5/2, or 2.5.

Hey guys please help find the area

V125BC [204]

Answer:

70.15 ft²

Step-by-step explanation:

The figure consists of two adjacent equilateral triangles (all angles are 60 degrees and all outer edges are 9 ft).

If we focus on one of these equilateral triangles, we can get the final area by multiplying the area of that one triangle by 2.

The formula for the area of a triangle is (1/2)(base)(height). Remembering to multiply this by 2, we get

area of figure = (base)(height)

√3

= (9 ft)(9 ft)(--------) = (81 ft²)(1.732) = 70.15 ft²

nlexa [21]

Answer:

4.06

Step-by-step explanation:

Given :

Scores Number of students

0 1

1 2

2 5

3 3

4 6

5 7

6 9

To Find: Mean

Solution:

Mean = $\frac{\text{Sum of all scores}}{\text{number of students}}$

Mean = $\frac{0 \times 1+1\times 2+2\times 5+3\times 3+4\times 6+5\times 7+6\times 9}{1+2+5+3+6+7+9}$

Mean = $\frac{134}{33}$

Mean = $4.06$

Hence, The Mean of baseball score is 4.06 .

Whats 2x + y = 10 5x - y = 18 in elimination method

Naya [18.7K]

2x + y = 10
5x - y = 18

7x = 28

x = 4

2(4) + y = 10

8 + y = 10

y = 2
