400x
1000x
Answer:
Simplify: (4x2 - 2x) - (-5x2 - 8x).
Solution:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
Answer: 3x(3x + 2)

What equation represents the slope intercept form of the line below Y intercept =(0,-2) slope = 2/3
Answer: [tex]y = \frac{2}{3} x - 2[/tex]
Step-by-step explanation:
The slope intercept form is y = mx + b
Where m is our slope and b is our y-intercept
We're given a slope of 2/3
We're given a y-intercept of -2
Substituting into y = mx + b gives
[tex]y = \frac{2}{3} x - 2[/tex]
Answer:
y = (2/3)x - 2
Step-by-step explanation:
Use the slope-intercept form y = mx + b. Here b = -2 and m = 2/3. Making these replacements, we get:
y = (2/3)x - 2

Isabel’s class has collected 90 cans in a food drive. They plan to sort the cans into n bags, with an equal number of cans in each bag. Write an expression to show how many cans there will be in each bag.
Answer:
90/n
Step-by-step explanation:
There are 90 cans, and each bag MUST have an equal amount of cans, so if we had, let's say 2 bags, then there would be 45 bags. We got this by doing 90/2. 2 being n, the expression would be 90/n.

Evaluate the following expression: 7 + 3b + 4b use a=3 and b=5
Answer:
222222222222224.705876
Answer:
42
Step-by-step explanation:
You would substitute B where is needs to go, 7 + 3(5) + 4(5). First multiply 3 x 5 to get 15, and then multiply 4 x 5 to get 20, 7 + 15 + 20. 7 + 15 = 22 + 20 = 42. I hope this helps.
3(3v-5) = 39
Simplify your answer as much as possible.
Answer:
v = 6
Step-by-step explanation:
Given
3(3v-5) = 39
So,
3v - 5 = 39 / 3
=> 3v - 5 = 13
=> 3v = 13 + 5
=> 3v = 18
=> v = 18 / 3
=> v = 6
#HopeItHelps
Answer:
V=6
Step-by-step explanation:
Hope this helped! :)
Simplifying
3(3v + -5) = 39
Reorder the terms:
3(-5 + 3v) = 39
(-5 * 3 + 3v * 3) = 39
(-15 + 9v) = 39
Solving
-15 + 9v = 39
Solving for variable 'v'.
Move all terms containing v to the left, all other terms to the right.
Add '15' to each side of the equation.
-15 + 15 + 9v = 39 + 15
Combine like terms: -15 + 15 = 0
0 + 9v = 39 + 15
9v = 39 + 15
Combine like terms: 39 + 15 = 54
9v = 54
Divide each side by '9'.
v = 6
Simplifying
v = 6

Solve the system by substitution.
3x-8y=-50
6y+=x
Answer:
substitution method is tricky until u get the hang of it. 6y=x so 3x-8y=-50 can be rewritten as 3(6y)-8y=-50.
Step-by-step explanation:
3x-8y=-50.........(1)
6y= x ..............(2)
Substituting x = 6y in (1)
3(6y) - 8y = -50
multiply 3(6y)
18y - 8y = -50
subtract 8y from 18y
10y = -50
divide to get y alone
y = -50/10
y = -5
now substitute. you know what y is. 6y=x / 6(-5)=x
solve :)
6y = x
6(-5) = x
-30 = x
x = -30
passes through (-1, -5) and (2, 6)
Answer:
[tex]y = \frac{11}{3}x + -\frac{4}{3}[/tex]
Step-by-step explanation:
[tex]y = mx + b\\m = \frac{-5 - 6}{-1 - 2} = \frac{-11}{-3} = \frac{11}{3} \\\\y = \frac{11}{3}x + b\\6 = \frac{11}{3}(2) + b\\6 = \frac{22}{3} + b \\6 - \frac{22}{3} = b \\b = -\frac{4}{3}\\\\y = \frac{11}{3}x + -\frac{4}{3}[/tex]

A line passes through the points (-4,-1) and (4,3) a second line passes through the points (-2,-2) and (2,6) at what point do the two lines intersect
Answer:10
Step-by-step explanation:
ASAP. Triangle ABC has angle measures as shown. complete sentences
(a) What is the value of x? Complete sentence. Show your work.
(b) What is the measure of each angle? Do the 3 angles add to 180 degrees? Show your work
In a triangle, the three angles ALWAYS add up to 180°
x + (6x + 10) + (x + 2) = 180
8x + 12 = 180
8x = 168
x = 21
To calculate the measure of each angle, substitute x in:
Angle A: 21
Angle B: 6(21)+10
Angle C: 21 + 2
Do the angles add up to 180 degrees? Just add the answer for A B and C and see if the sum is 180. It should be 180, if it isn't something is wrong with the calculation.
How to solve 3 3/5 - 2/3?
The value of the expression 3 ³/₅ - 2/3 in mixed fraction number will be 2 ¹⁴/₁₅.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The expression is given below.
⇒ 3 ³/₅ - 2/3
Convert the mixed fraction number into a fraction number. Then we have
⇒ 3 ³/₅
⇒ 18 / 5
Then the expression is written as,
⇒ 3 ³/₅ - 2/3
⇒ 18/5 - 2/3
⇒ (18 x 3 - 2 x 5) / 15
⇒ (54 - 10) / 15
⇒ 44 / 15
⇒ 2 ¹⁴/₁₅
The worth of the articulation 3 ³/₅ - 2/3 in the blended part number will be 2 ¹⁴/₁₅.

Which equation shows how (-10,8) can be used to write the equation of this line in point-slope from?
Options :
y – 8 = –0.15(x – 10)
y + 8 = –0.15(x – 10)
y – 8 = –0.2(x + 10)
y + 8 = –0.2(x – 10)
Answer:
y – 8 = –0.2(x + 10)
Step-by-step explanation:
(-10, 8)
General equation in point - slope form:
y - y1 = m(x - x1)
m = slope
Given the points : ( - 10, 8)
x1= - 10 ; y1 = 8
y - y1 = m(x - x1)
Substitute the values of x and y into the equation :
y - 8 = m(x - - 10)
y - 8 = m(x + 10)
The best option which fits is :
y – 8 = –0.2(x + 10)
