solve the system by substitution 3x-y=10 2x=y
Answer
X=10 and y=20
Step-by-step explanation:
since y=2x, you need to substitute that into the equation to get:
3x-(2x)=10
And evaluate:
x=10
Then substitute 10 into the equation: 2x=y:
2(10)=y
evaluate:
20=y
Now go back to the original equation to check your answer and substitute the values in:
3(10)-(20)=10
30-20=10
10=10
M(-5,2) and N(5,2) are the endpoints of the sedment MN on the cordinate plane what is the length of MN
Answer:
10 units
Step-by-step explanation:
Given data
The points are
M(-5,2) and N(5,2)
x1=-5
y1= 2
x2=5
y2= 2
The expression for the distance between two points is
d=√((x_2-x_1)²+(y_2-y_1)²)
substitute
d=√((5-(-5))²+(2-2)²)
d=√10²+0²
d=√100
d=10
Hence the distance is 10 units
Pls help. I really don’t understand how to do this.
Answer:
k = 6
Step-by-step explanation:
Given f(x) then f(x + a) is a horizontal translation of f(x)
• If a > 0 then a shift to the left of a units
• If a < 0 then a shift to the right of a units
Here g(x) is the graph of f(x) shifted 6 units to the left
Then
g(x) = f(x + 6) → with k = 6

Find the length of side x in simplest radical form with a rational denominator.
Answer:
x = 4
Step-by-step explanation:
Using the sine or cosine ratio.
Using the sine ratio in the right triangle and the exact value
sin30° = [tex]\frac{1}{2}[/tex] , then
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{2}{x}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
x = 4
You spin the spinner twice,
What is the probability of landing on an 8 and then landing on an 8?
Answer:
The probability of landing on 8 twice is 1/64
Step-by-step explanation:
If you spin the spinner once, there are 8 possibilities each time (1-8). The possibility of landing on the number 8 is 1 of these 8 possibilities. Its probability is therefore 1/8
Each spin is independent. In other words, the spins do not affect each other. The number you land on during the first spin does not impact the second spin's number. The probability of landing on 8 the second time is the same as the first time: 1/8
Because the two events are independent, we find the probability of them both occurring by multiplying them together.
1/8 times 1/8= 1/64
hope this helps:)

what two numbers multiply to 20 and add up to 9
Answer:
4 and 5
Step-by-step explanation:
The solution of the numbers 4 and 5 that gives multiplied by 20 and adds up to 9.
Used the concept of the equation that states,
An equation is a group of numerical variables and functions that have been combined using operations like addition, subtraction, multiplication, and division.
Given that,
The multiplication of two numbers is 20.
And, the addition of both numbers is 9.
Let us assume that the numbers are x and y.
Hence the equation for the given conditions,
[tex]x \times y = 20[/tex] ... (i)
[tex]x + y = 9[/tex] ... (ii)
From (ii);
[tex]x = 9 - y[/tex]
Substitute in (i);
[tex](9 - y) \times y = 20[/tex]
[tex]9y - y^2 = 20[/tex]
[tex]y^2 - 9y + 20 = 0[/tex]
[tex]y^2 - (5 + 4)y + 20 = 0[/tex]
[tex]y^2 - 5y - 4y + 20 = 0[/tex]
[tex]y (y - 5) - 4 (y - 5) = 0[/tex]
[tex](y - 5) (y - 4) = 0\\[/tex]
This gives,
[tex]y = 5\\y = 4[/tex]
From (i);
Substitute y = 5;
[tex]x = 9 - 5\\x = 4[/tex]
Substitute y = 4;
[tex]x = 9 - 4\\x = 5[/tex]
Therefore, the numbers are 5 and 4.

Answer: Y-(-1)= 3/4(x-1)
Step-by-step explanation:
*First find the slope*
y2-y1/x2-x1 ==> 2-(-1)/5-1 ==> 3/4
Point-slope form ==> y-y1=m(x-x1)
y-(-1)=3/4(x-1)

20/3=2(w+2/3)
What’s the value of w
Answer: w=8/3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
20 /3 =2(w+ ( 2 /3 )
20 /3 =(2)(w)+(2)( 2 /3 )(Distribute)
20 /3 =2w+ 4 /3
Step 2: Flip the equation.
2w+ 4 /3 = 20 /3
Subtract 4/3 from each side: 2w+ 4 /3 − 4 /3 = 20 /3 − 4 /3
Divide both sides by 2: 2w/ 2 =16 3 /2
Answer w=8/3
Answer:
w=8/3

Classify the polynomial 30x
Answer:
C: monomial
Step-by-step explanation:
You need to classify the polynomial. But before we start, let's recall the basic classifications of polynomials:
Monomials
Binomials
Trinomials
Polynomials
What are monomials?
- expressions with only one term
What are binomials?
- expressions with two terms
What are trinomials?
- expressions with three terms
What are polynomials?
- expressions with four or more terms
30x is an expression with only one term, so it's a monomial.
∴ letter C: monomial
The length of a rectangle can be rpresented by the expression x+6. If the area of the rectangle is 2x^2+8x-24, what is the expression for the width.
Answer:
2(x − 2)
Step-by-step explanation:
The length of a rectangle can be rpresented by the expression x+6. If the area of the rectangle is 2x^2+8x-24, what is the expression for the width.
The formula for the area of a rectangle = Length × Width
Area of the rectangle = 2x² + 8x - 24
Length = x + 6
We can find the width of the rectangle be factoring the Area
Hence, factorising
2x² + 8x - 24
= 2(x − 2)( x + 6)
Therefore, the Width of the rectangle =2(x − 2)
