Explain the steps you would take to graph 2x-3y>15
Answer:
Step-by-step explanation:
In order to graph this properly, you will have to rewrite the inequality first
To do this you will have to get y by itself
First subtract 2x from both sides of the inequality
This will give you -3y>15-2x
Then you will divide -3 from both sides. When dividing by a negative, both sides of the inequality will flip
-3y/-3 < 15/-3 + -2x/-3
This should end up looking like this once it's divided
y < -5+ 2x/3
Rewrite in slope intercept form
y < 2/3x -5
Your slope= 2/3
Your y-intercept=(0,-5)
In order to graph this you will have to mark your y-intercept at (0,-5) From there you will plot the points going up and down using your slope 2/3.
Remember 2/3= rise over run, meaning you will go up 2 and across right 3 to receive your second point going up. When you are graphing down it will be two down and across left 3.
What is the y-intercept? O (0, -5) O (0-2) O (0, 2) O (0, 4)
Answer:
(0,-5)
Step-by-step explanation:
the y-intercept is when the line passes through the y-axis
Answer:
(0,-5)
Step-by-step explanation:
the y-intercept is when the line passes through the y-axis
Ben drinks tea at an incredible rate. He drinks 3\
123 2 1
Answer:
He drinks 5 1/4 liters of tea in one hour.
Step-by-step explanation:
Ben drinks 3 1/2 liters of tea every 40 minutes.
This means that he would drink 1 3/4 of tea every 20 minutes (divide both sides by 2).
Now, let's multiply each side by 3.
1.75 * 3 = 5.25 (aka 5 1/4)
20 * 3 = 60 minutes (an hour)

4. Solve 5x + 25 = 250 x = ?* Enter the number value only.
Answer: x = 5/49 ; 0.102041
Step-by-step explanation:
Subtract 5x on both sides. 25 = 245xDivide by 245 on both sides. x = 5/49. As a decimal, it is approximately 0.102041.What is the expression [tex]x^2+14x+40[/tex] in factored form?
Answer:
b
Step-by-step explanation:
since x is squared, you would put that into both parenthesis, so you should have (x)(x) right now
then you need to find factors of 40 that add to 14
factors of 40: 40 and 1, 20, and 2, 4 and 10, 5 and 8
4 and 10 multiply to equal 40 and add to equal 14
put each factor into a parenthesis
so now you should have (x+10) (x+4)
side note: if the number 40 was negative then one of the factors would have to be negative, this would result in (x+10) (x-4) or (x-10) (x+4)

1. SOLVE FOR X 3x + 2 = 2x + 9
O x = 9
O x = 7
O x = 5
X = 3
Answer:
x =7
Step-by-step explanation:
Answer:
x = 7
Step-by-step explanation:
Given
3x + 2 = 2x + 9 ( subtract 2x from both sides )
x + 2 = 9 ( subtract 2 from both sides )
x = 7
heelppppppppppp pleaseee
Answer:
x = -1
Step-by-step explanation:
6 -8x = 6x -9x +11
Combine like terms
6 -8x = -3x+11
Add 8x to each side
6-8x +8x = -3x+8x +11
6 = 5x+11
Subtract 11 from each side
6-11 = 5x+11-11
-5 =5x
Divide each side by 5
-5/5 = 5x/5
-1 =x

R
Answer:
9
Step-by-step explanation:
H=1/2 * B
N=H-5= 1/2 * B-5
B+H+N= B+(1/2 *B) + (1/2 *B-5)=31
2B-5=31
B=18
H=1/2 *B=9
Find the equation of the line that contains the points (6,3) and (9,4) Write the equation in the form y=mx+b HELP ASAP
Answer:
y = 1/3x + 1
Step-by-step explanation:
find the slope by using y2-y1/x2-x14-3/9-6
1/3. slope = 1/3 = m
2. plug the values into the equation to find y-int. You can use whichever point is given to you
I'll use (6,3)
y = mx + b
3 = 1/3(6)+b
1/3(6)=2
3 = 2 + b
3. subtract 2 from both sides and you get b
b = 1
So, the equation of the line would be
y = 1/3x + 1

Josie makes fruit punch by mixing fruit juice and lemonade in the ratio 3:4. She needs to make 49 liters of punch for the party. How much of each ingredient does she need
She would need 21 liters of fruit juice and 28 liters of lemonade.
Answer:
juice = 21lemonade = 28
Step-by-step explanation:
given:
ratio of juice and lemonade = 3:4
She needs to make 49 liters of punch for the party.
find:
How much of each ingredient does she need
solution:
add the ratio 3 + 4 = 7
total punch divide by the total ratio
49 / 7 = 7 (coefficient)
juice 3 x 7 = 21
lemonade 4 x 7 = 28
total = 49

7. Work out the gradient of the line y + 7x = 8
Is anyone able to help much appreciated
Answer:
[tex]gradient \: = - 7[/tex]
Step-by-step explanation:
[tex]y + 7x = 8 \\ y = - 7x + 8[/tex]
According to,
[tex]y = mx + c \\ [/tex]
m = gradient
So,
[tex]y = - 7x + 8[/tex]
[tex]m = - 7[/tex]
Answer:
-7
Step-by-step explanation:
equation=y+7x=8
y=-7x+8
the gradient is always the x co-efficient
therefore the gradient is -7
