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
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)

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

Find the distance ab give your answer correct to 1. Decimal place
Answer:
AB=10
AB=7.2
Step-by-step explanation:
AB= √{(9-1)²+(8-2)²} = √{8²+6²}=√{64+36}=√100 =10
AB= √{(6-2)²+(2-8)²} = √{4²+(-6)²}=√{16+36}=√52 =7.2
The distance between points A(1, 2) and B(9,8) is 10 and the distance between points A(2, 6) and B(8, 2) is 7.2.
What is a coordinate plane ?A coordinate plane is a plane in which a set of two number lines are represented, horizontal line is called x-axis and vertical line is called y-axis.
In the first coordinate plane,
The coordinate of point A is (1, 2) and coordinate of point B is (9,8),
To find distance, use distance formula between two points (x₁, y₁) and (x₂, y₂) is [tex]\sqrt{(x_2 - x_1)^2+ (y_2 -y_1)^2)}[/tex]
Thd distance between A(1, 2) and B(9,8),
AB= [tex]\sqrt{{(9-1)^2+(8-2)^2}}[/tex] = [tex]\sqrt{{8^2+6^2}}[/tex]=[tex]\sqrt{{64+36}}[/tex]=[tex]\sqrt{100}[/tex] =10
In the second coordinate plane,
The coordinate of point A is (2, 6) and coordinate of point B is (8, 2),
To find distance, use distance formula between two points (x₁, y₁) and (x₂, y₂) is [tex]\sqrt{(x_2 - x_1)^2+ (y_2 -y_1)^2)}[/tex]
The distance between A(2, 6) and B(8, 2),
AB= [tex]\sqrt{{(8-2)^2+(2-6)^2} }[/tex]= [tex]\sqrt{6^2+(-4)^2}}[/tex]=[tex]\sqrt{{36+16}}[/tex]=[tex]\sqrt{52}[/tex] =7.2

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
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.

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.
