Answer:
x< -8.125
Step-by-step explanation:
7(x+4) < 2(x-5) -3(x+9)
distribute 7, 2, -3 to the parentheses to the right
7x+28<2x-10-3x-27
add like terms
7x+28<x-37
add x to 7x and subtract -28 to -37
8x<-65
divide both sides by 8
x<-8.125 or (-65/8)

{2y=x−4
{4x+3y=5
Answers
Answer:
(2, -1)
Step-by-step explanation:
We can subtract x from both sides from the first equation, then multiply the first equation by 4, so it's easier to solve later:
-4x+8y = -16
4x+3y = 5
Then, we can add the 2 equations, so the x cancels out:
11y = -11
y=-1
Now, we can plug y as -1 to any of the equations above:
4x+3*(-1)=5
4x=8
x=2
Therefore, the solution to these 2 equations are (2, -1)
The value of the variables 'x' and 'y' will be 2 and negative 1, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The system of equations is given below.
x = 2y + 4 ...1
4x + 3y = 5 ...2
From equations 1 and 2, then we have
4(2y + 4) + 3y = 5
8y + 16 + 3y = 5
11y = - 11
y = -1
Then the value of 'x' is given as,
x = 2 (-1) + 4
x = - 2 + 4
x = 2
The value of the variables 'x' and 'y' will be 2 and negative 1, respectively.

Which function has a zero with a multiplicity of 2?
Answers
Answer:p(x)=(x-1)(x-3)²
Step-by-step explanation:
The polynomial p(x)=(x-1)(x-3)² is a 3rd degree polynomial, but it has only 2 distinct zeros. This is because the zero x=3, which is related to the factor (x-3)², repeats twice. This is called multiplicity. It means that x=3 is a zero of multiplicity 2, and x=1 is a zero of multiplicity 1.

A standard paper clip is 1 1/4
inches long. If you laid 75 paper
clips end to end, how long would
the line of paper clips be?
Answers
The line of 75 paper clips end to end would be 93 3/4 inches long.
To calculate the total length of the line formed by laying 75 paper clips end to end, we need to find the sum of the lengths of all the paper clips.
Each paper clip is 1 1/4 inches long. To add these lengths together, we can convert 1 1/4 to an improper fraction, which is 5/4 inches.
Now, multiply the length of one paper clip (5/4 inches) by the number of paper clips (75):
Total length = (5/4) inches * 75
Next, multiply the whole number (75) by the numerator (5) and add it to the product of the denominator (4) and the whole number:
Total length = (75 * 5 + 0) / 4
Total length = 375/4
Now, we can simplify the fraction:
Total length = 93 3/4 inches
The line of 75 paper clips end to end would be 93 3/4 inches long.

what is negative one eighth of a number is -3/4 as an equation?
will name the brainliest!
Answers
Answer:
The equation is [tex]-\frac{1}{8}[/tex] x = [tex]-\frac{3}{4}[/tex]
Step-by-step explanation:
The Equation is formed from two sides equal to each other
In the algebraic statement "is" means equalIn the algebraic statement "of" means times (×)∵ One eighth means [tex]\frac{1}{8}[/tex]
∴ Negative one eighth means [tex]-\frac{1}{8}[/tex]
→ Assume that the number is x
∵ "of" means times
∴ Negative one eighth of a number = [tex]-\frac{1}{8}[/tex] × (x)
∴ Negative one eighth of a number = [tex]-\frac{1}{8}[/tex] x
∵ Negative one eighth of a number is [tex]-\frac{3}{4}[/tex]
→ "is" means equal, so the left side is [tex]-\frac{1}{8}[/tex] x and the right side is [tex]-\frac{3}{4}[/tex]
∴ [tex]-\frac{1}{8}[/tex] x = [tex]-\frac{3}{4}[/tex] ⇒ Equation
∴ The equation is [tex]-\frac{1}{8}[/tex] x = [tex]-\frac{3}{4}[/tex]

the sum of 2 number is 64,twice the large number plus five times the smaller number is 20 find the 2 numbers
Answers
Answer:
The two numbers are: - 36 and 100
Step-by-step explanation:
let the smaller number = x, let the larger number = y
then...
x + y = 64
5x + 2y = 20
use substitution: y = (64 - x)
5x + 2(64 - x) = 20
3x = 20 - 128 = - 108
x = - 36
So the two numbers are: - 36 and 100
