PLEASE HELP!!

what is true about the graph of the line y= -3x + 4?


a) the line has a slope of 4

b) the line has a slope of -4

c) the line crosses the y-axis below the origin

d) the line crosses the y-axis above the origin

Answer:

2x + y = 12 & x = 9 - 2y --- (x = 5, y = 2)

x + 3y = 16 & 2x - y = 11 --- (x = 7, y = 3)

y = 11 - 2x & 4x - 3y = -13 --- (x = 2, y = 7)

2x + y = 11 & x - 2y = -7 --- (x = 3, y = 5)

Step-by-step explanation:

Answer:

y=1/13x - 4/13

Step-by-step explanation:

Just follow the slope intercept form formula-

Formula: y= mx+b

Key:

y = y-coordinate

m = slope

x = x-coordinate

b = y-intercept

Feel free to ask if you have any questions, hope this helps!(:

Answer:

28.6 inches

Step-by-step explanation:

3 percent of 52 is 1.56 so it is melting at a rate of 1.56 inches per minute

15x1.56 is 23.4

52-23.4=28.6 so after 15 minutes the sculpture will be only 28.6 inches tall

Answer:

Draw a line of a givens point

Answer: b = 8

Step-by-step explanation: You have to divide (-4) on both sides and -32/-4= 8 so b =8

Answer:

Step-by-step explanation:

-32=4b

divide -4 by both sides

-4/-4=1

-32/-4=8

therefore, b=8

Step-by-step explanation:

General line equation: y = mx + c

When x = 0, y = 3. => (3) = m(0) + c, c = 3.

When x = -4, y = 5. => (5) = m(-4) + c,

5 = -4m + (3), -4m = 2, m = -0.5.

Hence the answer is y = -0.5x + 3.

Answer:

y=-[tex]\frac{1}{2}[/tex]+3

Step-by-step explanation:

To write the equation of the line in slope-intercept form, first calculate the slope of the line (m)

m=[tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]

=[tex]\frac{5-3}{-4-0}[/tex]

=2/-4

=-[tex]\frac{1}{2}[/tex]

next, calculate b by substituting a point (0, 3) into the equation

y=mx+b

3=(-1/2)(0)+b

b=3

final equation of line is: y=-[tex]\frac{1}{2}[/tex]+3

Answer:

19 units.

Step-by-step explanation:

Consider the below figure attached with this question.

From the below figure it is given that MN=PQ.

It is given that MP = 6x – 5, QR = 3x + 1, and RN = 6.

Since non parallel sides are equal, therefore it is an isosceles trapezoid.

The diagonals of an isosceles trapezoid are equal.

Substitute the given values.

The value of x is 4.

Hence, the measure of QN is 19 units.

The number of

Small candles = x = 12 candles

Large candles = y = 16 candles

Step-by-step explanation:

You sell small and large candles at a craft fair. You collect $144 selling a total of 28 candles. How many of each type of candle did you sell? A photo shows a small candle labeled 4 dollars each and a large candle labeled 6 dollars each.

Let the number of

Small candles = x

Large candles = y

Our system of equations is:

x + y = 28 .......... Equation 1

x = 28 - y

A photo shows a small candle labeled 4 dollars each and a large candle labeled 6 dollars each.

4x + 6y = 144......... Equation 2

Substitute 28 - y for x in Equation 2

4(28 - y) + 6y = 144

112 - 4y + 6y = 144

- 4y + 6y = 144 - 112

2y = 32

y = 32/2

y = 16 candles

x = 28 - y

x = 28 - 16

x = 12 candles

Therefore:

The number of

Small candles = x = 12 candles

Large candles = y = 16 candles

Answer:

24:8

Step-by-step explanation:

Given the following data;

Batch = eggs + sticks of butter

4 batches = 12:4

8 batches = 2 * 4 batches

Therefore, 8 batches = 2*(12:4)

8 batches = 24:8

Hence, the equivalent ratio Sierra would use if she wants to make 8 batches is 24 eggs to 8 sticks of butter.

Answer:

Step-by-step explanation:

the answer is 24:8

Answer:

-1/2

Step-by-step explanation:

according to what I learnt, the general form of every equation is y=mx+c where y is the y value, x is the x value, m is the slope and c is the y-intercept so the equation y-3= -1/2(x - 2) in the general form wil be :

y= -x/2+4 and so m= -x/2 ,that is -1/2

Answer:

Adult tickets sold =  225

Student Tickets sold =  375

Step-by-step explanation:

Let:

Adult tickets sold = x

Student Tickets sold = y

Total tickets sold = 600

So, we can write: x+y = 600

Total money collected = 3037.50

Cost of 1 Adult ticket = $6.00

Cost of one Student ticket = $4.50

So, we can write: 6x+4.5y=3037.50

Now, we get a system of equations, that if solved we can find values of x and y

Let:

[tex]x+y = 600--eq(1)\\6x+4.5y=3037.50--eq(2)[/tex]

We can solve using substitution method.

Finding value of x from eq(1) and putting it in eq(2)

[tex]We\:have\\x+y=600\\x=600-y[/tex]

Put in eq(2)

[tex]6x+4.5y=3037.50\\6(600-y)+4.5y=3037.50\\3600-6y+4.5y=3037.50\\-1.5y=3037.50-3600\\-1.5y=-562.5\\y=\frac{-562.5}{-1.5}\\y=375[/tex]

So, we get value of y = 375

Now put value of y in eq(1) to find value of x

[tex]x+y=600\\Put\:y=375\\x+375=600\\x=600-375\\x=225[/tex]

So, we get value of x = 225

The Tickets sold will be:

Adult tickets sold = x = 225

Student Tickets sold = y = 375
