Answer:

Q2: slope = -½

Q3: slope = 1

Step-by-step explanation:

If the equation of the line is in the form y = mx+b, then m is the slope of the line and b is the y-intercept (the point where the line crosses the x-axis).

y = -½x, so the slope of the line is -½

y = x+15, so the slope of the line is 1

Answer:

36.45

Step-by-step explanation:

tan 32 = a/35

x = 23.1

tan 70 = b/23.1

y = 28.2

x^2 = a^2+b^2

= 23 .1^2 + 28.2^2

= 36.45

An investment of 11,000 is made into an account that earns 4.25% annual compound interest for 30 months. Assuming no other depos
LenKa [72]

Answer:

It should be $12168.75

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4.25%/100 = 0.0425 per year,

then, solving our equation

I = 11000 × 0.0425 × 2.5 = 1168.75

I = $ 1,168.75

The simple interest accumulated

on a principal of $ 11,000.00

at a rate of 4.25% per year

for 2.5 years is $ 1,168.75.

1,168.75 + 11000 = 12168.75

What is the rule to represent the number of tiles in figure x?
dezoksy [38]
Figure 1 has 8 tiles
figure 2 has 14 tiles
figure 3 has 22 tiles

I'm guessing the 2 on the side hints for us to do something+2
the inside parts are
figure 1: 6
figure 2: 12
figure 3: 20

hmm, the width is 1+number figure
height is 2+figure number

so therefor, figure x is (1+x)(2+x)+2

so the rule is figure x has (x+1)(x+2)+2 or x^2+3x+4 tiles



a. the rule is figure x has (x+1)(x+2)+2 or x^2+3x+4 tiles
b. it is quadratic because it has x^2 in it
