The slope-intercept form is

y = mx + b,

where m = slope, and b = y-intercept

Now we get the y-intercept and the slope from the graph.

The y-intercept, b, is 4.

To find the slope, start at (-2, 0). Go up 4 and right 2 to point (0, 2). That is a rise of 4 and a run of 2.

m = slope = rise/run = 4/2 = 2

Equation:

y = mx + b

y = 2x + 4

Answer: y = 2x + 4

There are 38 roses, 35 tulips, and 22 lilies. The Commutative

Sever21 [200]

there isnt a list of options given but should be something like

38 + 35 + 22 = 22 + 35 + 38

or maybe

38r + 35t + 22l = 22l + 35t + 38r

it equals 95

It takes ten identical pieces to form a circular track for a pair of toy racing cars. If the inside arc of each piece is 3.4 inc

dsp73

Length of outer track = sum of length of 10 pieces = circumference of the outer circle

if R is the Radius of outer circle then...

Circumference of the outer track = 2pi*R

Similarly the circumference of the inner track (with radius r) = 2pi*r

length of each outer piece is 3.4 inch more than length of inner piece

So total outer length is 10*3.4 =34 inches more than the inner length.

=> Outer Circumference - Inner Circumference = 34 inches

=> 2pi*R - 2pi*r = 34

=> 2pi(R -r) = 34

=> R-r = 34/2pi = 5.41 inches

=> R-r = Width of the track = 5.41 inches

A new car is purchased for 22400 dollars. The value of the car depreciates at 11% per year. To the nearest tenth of a year , how

m_a_m_a [10]

Answer:

t= 12.9 years

Step-by-step explanation:

Value after t years = initial value ( 1 - r )^t

Where,

Value after t years= $5000

Initial value = $22,400

r= depreciation rate = 11%

t= length of time (years)

Value after t years = initial value ( 1 - r )^t

5000 = 22,400 ( 1 - 0.11)^t

5000 = 22,400(0.89)^t

Divide both sides by 22,400

(0.89)^t = 5000 / 22,400

(0.89)^t = 0.2232

Take the log of both sides

t log 0.89 = log 0.2232

t= log 0.2232 / log 0.89

= -0.6513 / -0.0506

= 12.87

t= 12.9 years

△WPJ∼△DNJ What is PWPW ? Enter your answer in the box.

Kruka [31]

Use CPCTC and make ratios and proportionalities to find the value of segment PW:

If △WPJ∼△DNJ, then according to CPCTC, WP must be proportional to DN and PJ must be proportional to JN. Now, we can make a ratio:

$\frac{WP}{DN}= \frac{PJ}{NJ}$

Substitute the values that are given in the diagram.
DN=87.5
NJ=56
PJ=64

$\frac{WP}{87.5}= \frac{64}{56}$

Solve for x. You can do it by cross-multiplication.

$\frac{WP}{87.5}= \frac{64}{56} \\ 56*WP=64*87.5 \\ 56*WP=5600 \\ WP=100$

The measure of segment WP is 100 meters.
