Help me pls UoU Uwu<br> \djjn

Answer:

y = 4x + 14

Step-by-step explanation:

slope-intercept form: y = mx + b

Slope formula: $\frac{y2-y1}{x2-x1}$

To write the equation in y = mx + b form, we need to find the slope(m) and the y-intercept(b) of the equation.

To find the slope, take two points from the table(in this example I'll use points (0, 14) and (1, 18)) and input them into the slope formula:

$\frac{18-14}{1-0}$

Simplify:

18 - 14 = 4

1 - 0 = 1

$\frac{4}{1}=4$

The slope is 4.

To find the y-intercept, input the values of the slope and one point(in this example I'll use point (1, 18)) into the equation format and solve for b:

y = mx + b

18 = 4(1) + b

18 = 4 + b

14 = b

The y-intercept is 14.

Now that we know the slope and the y-intercept, we can write the equation:

y = 4x + 14

HELP I WILL GIVE BRAINLEIST OR WHATEVER 50 POINTS

Ilya [14]

answer:

a. scarf costs today = $6

b. scarf costs 3 days from now = $3

step-by-step explanation:

1/2 off means you would multiply the amount by 1/2 then subtract

a. original price of scarf: $12

12 X 1/2 = 6

12 - 6 = 6

— scarf costs today = $6

do the same thing but this time it is a different number

b. 12 X 3/4 = 9

12 - 9 = 3

— scarf costs 3 days from now = $3

Find the probability for the given situations, and then match the situations with the number of times each event is predicted to

Ulleksa [173]

Answer:

(a)3

(b)4

(d)5

Step-by-step explanation:

(a)Josie rolls a six-sided die 18 times.

P(she rolls a two)=1/6

Therefore, the estimated number of times she rolls a two in 18 trials

=1/6 X 18

(b)Slips of paper are numbered 1 through 10.

P(the number 10 appear)=1/10

If one slip is drawn and replaced 40 times, expected number of 10

=1/10 X 40

(c)A spinner consists of 10 equal- sized spaces: 2 red, 3 black, and 5 white.

P(red)=2/10

If the spinner is spun 30 times, expected number of red space

=2/10 X 30

(d)A card is picked from a standard deck

P(drawing an ace)=4/52

If the card is picked 65 times and replaced each time.

Expected Number of Aces =4/52 X 65 =5

Paula walks 1/12 mile in 5/3 minutes. What rate is equivalent to the rate she walked?

mel-nik [20]

The rate that is equivalent to the rate Paula walked is 1/20 mile/minute OR 0.05 mile/minute

<h3>Calculating Rate </h3>

From the question, we are to determine the rate which is equivalent to the rate Paula walked

Using the formula,

$Rate = \frac{Distance}{Time}$

From the given information,

Distance = 1/12 mile

Time = 5/3 minutes

Putting the parameters into the formula, we get

$Rate =\frac{\frac{1}{12} }{\frac{5}{3} }$

$Rate = \frac{1}{12} \div \frac{5}{3}$

$Rate = \frac{1}{12} \times \frac{3}{5}$

$Rate = \frac{3}{60}$

$Rate = \frac{1}{20}$ mile/minute

Hence, the rate that is equivalent to the rate Paula walked is 1/20 mile/minute OR 0.05 mile/minute
