Answer:

D. 8.8

Step-by-step explanation:

As the pythagorean theorem.

A² + B² = C²,

5.4 × 5.4 + 7 × 7 = C²,

29.16 + 49 = C²,

78.16 = C²,

8.8 ≈ C

Step-by-step explanation:

Use y-intercept (0, -6) and slope -3/4 and put into y=mx+b form to solve for b

Remember that m is also known as slope!

-6=(-3/4 * 0) + b

b= -6

y= -3/4x - 6

A lawn-mowing company is trying to grow its business. it had 30 clients when they started its business and wants to increase by
Leona [35]

The function to represent the problem is f(x)=6x+24 and the range is 30\leqy\leq48.

<h3>What is arithmetic sequence formula?</h3>

If the terms of a sequence differ by a constant, we say the sequence is arithmetic. If the initial term (a_{0}) of the sequence is a and the common difference is d, then we have,

a_{n}=a+(n-1)d

Initial number of clients=30

Number increase per week= 6

So, we can make an arithmetic sequence fir six weeks

30,36,42,48

Here, first term, a=30

Common difference, d=6

Range is [30,48]

The explicit formula of an arithmetic sequence is

a_{n}=a+(n-1)d

Put a=30, d=6, n=x

a_{x}=30+(x-1)6

a_{x}=30+6x-6

a_{x}=6x+24

Therefore, The function to represent the problem is f(x)=6x+24 and the range is 30<=y<=48

I need help please with this math problem.
dezoksy [38]

Answer:

They are equal

Both answer is 65

Step-by-step explanation:

5x -30 = 2x +27

5x -2x = 27 +30

3x = 57

x = 57/3 = 19

5x -30 = 5(19) -30 = 65

2x +27 = 2(19) +27 = 65
