Find the slope of the line that passes through the points (-7,-5) and (4, -3).
Answer:
y = (-2/9)x
Step-by-step explanation:
Rise over run so between (-7,-5) and (4,-3) it goes up -2 and over 9 so -2/9. Put this next to x and boom you have the slope equation.
The Y- intercept form from the line whose slope is 2 and passes through (-7,11)
Answer:
y = 2x + 25
Step-by-step explanation:
Slope-Intercept Form: y = mx+b
Slope: m = 2
y = 2x + b
Solve for b:
y = 2x + b
11 = 2(-7) + b
11 = -14 + b
b = 25
y = 2x + 25

Answer:
1, 210.
2. 72 minutes.
3. 42 minutes
4. 2 inches.
5. 3 cents.
Step-by-step explanation:
1. First, divide 240 by 8, which will get you 30, now multiply 30 by 7 and you will get 210 which is your answer.
2. Your keyword here is times. So you know you will multiply. So just multiply 8 and 9, and your product is 72, so 72 minutes.
3. Multiply 3 1/2 by 12, or convert your fraction to a decimal, which in decimal form is 3.50. Your product would be 42.
4. Multiply 1/7 by 14, you should get 14/7, which is an improper fraction. Divide 14 by 7 and you will get 2 inches.
5. So here you have to find the unit rate. Divide the price by the quantity.
4.86/16.2=0.297530865
Round the number up, which would be 3. So it would be 3 cents

Answer:
Y=112 x=45
Step-by-step explanation:
y+68=180
so 180-68=112
y=112
y+(4x-2)+30=180
112+(4x-2)+30=180
140+4x=180
-140 to both sides
4x=180
divide by 4 to both sides
x=45

Step-by-step explanation:
1cm = 5km
?cm = 45km.
Solve by dividing 45 by 5.
If the distance is 45km, on the map this will be 9cm.
Solve the system of equations..
y=x +45
y= 5x + 13
Answer:
x = 8
y = 53
Step-by-step explanation:
Sub y = x + 45 into the second equation
x + 45 = 5x + 13
Rearrange by collecting the like terms
45 - 13 = 5x - x
32 = 4x
Divide both sides by 4
x = 8
Sub x = 8 into first equation (y = x + 45)
y = 8 + 45
y = 53

Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
The first step you should take is to distribute the 2, so if you do that it'll leave you with... [tex]12=-4v+2v+4[/tex]
Then you notice the like terms and then you have to combine them and that'll give you... [tex]12=-2v+4[/tex]
Now you subtract the 4 to both sides and get... [tex]8=-2v[/tex]
Lastly the fun step is to divide the -2 to both sides and to get the answer of...
[tex]v=-4[/tex]

If a=6 b=24 what is ab
Answer:
144
Step-by-step explanation:
Since a is 6 and b is 24 we would have to multiply both of those numbers which would give you 144.
Hope this helps and good luck!!
When a = 6 and b = 24, the value of the equation ab will be 144.
What is Algebra?Algebra is the study of mathematical symbols, while logic is the manipulation of those signifiers.
Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction is referred to as the PEMDAS rule. To answer the problem properly and accurately, this rule should be followed.
The expression is given below.
⇒ ab
If the values of "a" and "b" are 6 and 24, respectively. The expression's value is then provided as,
⇒ a × b
⇒ 6 × 24
⇒ 144
When a = 6 and b = 24, the value of the equation ab will be 144.
