Answer:

x=8 y=21

Step-by-step explanation:

7x+12=12x-28

x=8

plug in x

12x8-21=68

68+9y-77=180

y=21

The values of [x] and [y] will be 8 and 21 respectively.

This term indicates that the line 'l' is parallel to the line 'm'.

Given is the image and the measurement of angles.

It can be seen in the figure that, ∠(7x + 12) and ∠(12x - 28) from alternate interior angles as line 'l' and 'm' are parallel. These angles will be equal to each other. Therefore, we can write -

7x + 12 = 12x - 28

12x - 7x = 12 + 28

5x = 40

x = 8

Now, ∠(12x - 28) and ∠(9y - 77) form a straight angle. Therefore, we can write -

(12x - 28) + (9y - 77) = 180

(12 x 8 - 28) + (9y - 77) = 180

68 + 9y - 77 = 180

9y = 180 + 9

9y = 189

y = 21

Therefore, the values of [x] and [y] will be 8 and 21 respectively.

Answer:

y = 22.5 - 0.2t

Step-by-step explanation:

Given;

total number of candle, n = 22.5 ounce

Rate of candle burn, R = 1 ounce per 5 hours  [tex]= \frac{1 \ ounce}{5 \ hours} = 0.2 \ \frac{ounce}{hour}[/tex]

The amount of candle left = total initial value - amount burnt

let the amount let = y

y = 22.5 - 0.2t

where;

t is the time in which the candle is burnt

Thus, the equation for the amount of candle left is given by;

y = 22.5 - 0.2t

Answer:

the y-intercept in “y = -3x + 8 (slope-intercept form of the given line),” is 8.

Step-by-step explanation:

to find a parallel line to a given line, you must know how to write an equation of a line. You must also know how to put the equation of a line in slope-intercept form. Additionally, you must know how to identify the slope and the Y-intercept in the equation of a line. It is important to remember that parallel lines have equal slopes. Learn how to be able to find a parallel line.

Look at the equation of the line. Let’s say “3x + y = 8” is the equation of the given line. Put the equation of the given line in slope-intercept form: y = mx + b. Using “3x + y = 8” as the equation of the given line, put the equation in slope-intercept form by solving for "y" (subtracting -3x from both sides). You will get “y = -3x + 8.”

Identify the slope. The slope is the "m" in “y = mx + b.” Therefore, the slope in “y = -3x + 8 (slope-intercept form of the given line),” is -3. Identify the y-intercept. The y-intercept is the b in “y = mx + b.” Therefore, the y-intercept in “y = -3x + 8 (slope-intercept form of the given line),” is 8.

Answer:

-1170

Step-by-step explanation:

I hope this helps! :)))

Answer:

-45*26-1170

Step-by-step explanation:

Answer:

it would be 750/500

Step-by-step explanation:

150% of 500 is 750

Step-by-step explanation:

(a) If M is a function of G (M is the y-axis and G is the x-axis), then the linear function is approximately:

M = 20G

(b) If G is a function of M (G is the y-axis and M is the x-axis), then the linear function is approximately:

G = M / 20

(c) The two functions are inverse of each other.  The first function tells us how many miles she can drive with a certain number of gallons.  The second function tells us how many gallons she needs to drive a certain number of miles.

(d) There are multiple things that affect fuel mileage.  These include:

Speed - idling at a red light or driving at high speeds will lower your mileage.

Weather - high winds will lower your mileage.

Weight - adding weight (even the weight of the gas itself) will lower your mileage.

Tires - low pressure in the tires will lower your mileage.

The given table is an illustration of a linear scatter plot, where:

(a) M as a function of G

From the table, we have the following points:

[tex](G_1,M_1) = (1,19)[/tex]

[tex](G_2,M_2) = (11,218)[/tex]

Calculate the slope (m)

[tex]m = \frac{M_2 - M_1}{G_2 - G_1}[/tex]

[tex]m = \frac{218-19}{11-1}[/tex]

[tex]m = \frac{199}{10}[/tex]

[tex]m = 19.9[/tex]

The equation is then calculated using the following linear equation formula:

[tex]M = m(G - G_1) + M_1[/tex]

[tex]M = 19.9(G - 1) + 19[/tex]

[tex]M = 19.9G - 19.9 + 19[/tex]

[tex]M = 19.9G -0.9[/tex]

(b) G as a function of M

From the table, we have the following points:

[tex](M_1,G_1) = (19,1)[/tex]

[tex](M_2,G_2) = (218,11)[/tex]

Calculate the slope (m)

[tex]m = \frac{G_2 - G_1}{M_2 - M_1}[/tex]

[tex]m = \frac{11-1}{218-19}[/tex]

[tex]m = \frac{10}{199}[/tex]

The equation is then calculated as follows:

[tex]G = m(M - M_1) + G_1[/tex]

[tex]G = \frac{1}{19.9}(M - 19) + 1[/tex]

[tex]G = \frac{1}{19.9}M - \frac{19}{19.9} + 1[/tex]

[tex]G = \frac{1}{19.9}M - \frac{19-19.9}{19.9}[/tex]

[tex]G = \frac{1}{19.9}M - \frac{-0.9}{19.9}[/tex]

[tex]G = \frac{1}{19.9}M + \frac{0.9}{19.9}[/tex]

[tex]G = \frac{10}{199}M + \frac{9}{199}[/tex]

(c) How (a) and (b) compares

Functions (a) and (b) are both inverse functions of one another;

Because they both represent inverse functions, both are useful models

(d) Reasons points do not fit in the equation

Some reasons why the points do not fit are:

When any of these happens, the mileage will be affected because she won't be able to capture the accurate data by the time she continues her trip.

Answer:

y = -3/2x + 3

Step-by-step explanation:

If two lines are parallel to each other the slopes are the same.

So line w's  slope would be the same as line g's -3/2

Now all we have to do is pug in the points to find the y-intercept.

-3 = -3/2(4) + b (b represents the y-intercepts)

-3 = -6 + b (add 6 on both sides)

3 = b

y = -3/2x + 3 is the equation for w.

Answer:

the second one is false

Answer:

Answer B is false.

Step-by-step explanation:

The left side  "2"  is less than the right side  "8" , which means that the given statement is false.

If f(1) = 1 that means c is -2 because when you substitute x = 1 and when c = -2, you'll get f(1) = -2(1)+3 = -2+3 = 1

So the constant c is -2 and that means the value of f(-4) is

f(-4)=-2(-4)+3=8+3=11

Thus, the value of f(-4) is 11.

About why does "c" have to be -2, here's the proof.

 Given y = f(x), therefore.

y=cx+3

Since when x = 1 and y = 1, then Substitute x = 1 and y = 1, thus 1 = c+3

1 - 3 = c and therefore, -2 = c #

So this is the proof that c = -2
