2x - y = -5 solve for y
Answer:
y=5+2x
Step-by-step explanation:
The Solution of the given 2x - y = -5 expression for y will be y = 2x 5.
What is algebraic Expression?Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.
Given, an algebraic expression 2x - y = -5
Solution of the given expression for the variable y
=> 2x - y = -5
Simplifying the equation
=> 2x - y = -5
add variables y and 5 on both sides
=> 2x - y +y + 5 = -5 + y + 5
=> 2x +5 = y
Therefore, the Solution of the given expression for y will be y = 2x + 5.

Theresa is making bracelets with beads she has 64 red beads and 40 yellow beads each of the braces will have the same number of red beads and yellow beads that wants to use up all of the beads she has for the bracelets what is the largest number of braces she can make
Answer:
8 bracelets
Step-by-step explanation:
Given
Yellow = 40 beads
Red = 64 beads
Required
Highest number of bracelets
To answer this question, we simply need to determine the highest common factor of the given parameters.
40 = 2³ * 5
64 = 2⁶
HCF = 2³
HCF = 2 * 2 * 2
HCF = 8
Hence, the maximum number of bracelets is 8

O FIX) - - 2x + 9
O f(x) = -2x - 6
Of(x) - 2x - 6
O f(x) = 2x + 9
Answer:
[tex]f(x)= -2x + 9[/tex]
Step-by-step explanation:
The table is not properly formatted:
We have:
x ------- y
0 ------- 9
1 ------- 7
2 ------- 5
3 ------- 3
4 ------- 1
Required
Determine the linear equation
Since, it is a linear equation.
We need to first determine the slope.
Take any to corresponding values of x and y
[tex](x_1,y_1) = (0,9)[/tex]
[tex](x_2,y_2) = (4,1)[/tex]
Slope is then calculated as thus:
[tex]m = \frac{y_1 - y_2}{x_1 - x_2}[/tex]
[tex]m = \frac{9 - 1}{0 - 4}[/tex]
[tex]m = \frac{8}{- 4}[/tex]
[tex]m = -2[/tex]
The linear equation is then calculated as thus:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 9 = -2(x - 0)[/tex]
[tex]y - 9 = -2x[/tex]
Add 9 to both sides
[tex]y - 9 + 9= -2x + 9[/tex]
[tex]y = -2x + 9[/tex]
[tex]f(x)= -2x + 9[/tex]

Resuelve para k.
35 - k = 4
Answer:
k = 31
Step-by-step explanation:
Solve for k:
35 - k = 4
Subtract 35 from both sides:
(35 - 35) - k = 4 - 35
35 - 35 = 0:
-k = 4 - 35
4 - 35 = -31:
-k = -31
Multiply both sides of -k = -31 by -1:
(-k)/(-1) = 31
(-1)/(-1) = 1:
Answer: k = 31
Trent and Vivian go to the basketball court at the park for 45 minutes after school to practice shooting free throws. Each person shoots for an equal amount of time, while the other person rebounds the ball. How long does each person shoot free throws? Write your answer as a proper fraction or mixed number.
Answer:
22¹/₂ minutes
Step-by-step explanation:
If Trent and Vivian go to the basketball court at the park for 45 minutes after school to practice shooting free throws, the total time it takes for the both of them to shoot free throws is 45 minutes.
Let the amount of time Trent and Vivian shoot the free throws be t₁ and t₂ respectively.
Since they both throw at equal times, t₁ = t₂ = t.
Now t₁ + t₂ = 45 the total time it takes to shoot the free throws.
Since, t₁ = t₂ = t.
t₁ + t₂ = 45
substituting t into the equation, we have
t + t = 45
adding the t's, we have
2t = 45
dividing both sides by 2, we have
t = 45/2
t = 22¹/₂ minutes
So, it takes each person 22¹/₂ minutes to shoot free throws.
Answer:
22 1/2 minutes
Step-by-step explanation:
45 divided by two =22 1/2

What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the expression is 4(x+3)=52. To prove put the value of x = 10,
4(x+3)=52
4 ( 10 + 3 ) = 52
4 x 13 = 52
52 = 52
Hence, the expression is true for the value of x = 10.
