Answer:
Step-by-step explanation:
• The y-intercept represents a starting salary of $32,500 for a new employee. • The slope represents an additional $2,500 in salary for each additional year of employment. • If the starting salary for a new employee is changed to $35,000 and the yearly salary increase is unchanged, the new equation would be y = 2,500 x + 35,000 . • If the yearly salary increase is changed to $3,000 , the new equation would be y = 3,000 x + 32,500 .

after completing the square what are the solutions to the quadratic equation below
x²-5x-6=3
Answer:
x = 5/2 + sqrt(61)/2 or x = 5/2 - sqrt(61)/2
Step-by-step explanation:
Solve for x over the real numbers:
x^2 - 5 x - 6 = 3
Hint: | Solve the quadratic equation by completing the square.
Add 6 to both sides:
x^2 - 5 x = 9
Hint: | Take one half of the coefficient of x and square it, then add it to both sides.
Add 25/4 to both sides:
x^2 - 5 x + 25/4 = 61/4
Hint: | Factor the left hand side.
Write the left hand side as a square:
(x - 5/2)^2 = 61/4
Hint: | Eliminate the exponent on the left hand side.
Take the square root of both sides:
x - 5/2 = sqrt(61)/2 or x - 5/2 = -sqrt(61)/2
Hint: | Look at the first equation: Solve for x.
Add 5/2 to both sides:
x = 5/2 + sqrt(61)/2 or x - 5/2 = -sqrt(61)/2
Hint: | Look at the second equation: Solve for x.
Add 5/2 to both sides:
Answer: x = 5/2 + sqrt(61)/2 or x = 5/2 - sqrt(61)/2

Step-by-step explanation:
here this might help a little Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.

B.the expression 10w+2w shows the length of is 10 times the width
C.the expression 5(w+w+w+w+w) shows the perimiter is 5 times the width
D.the expression 2(5w)+2w shows the length is 5 times the width
E. the expression 10+w shows the perimiter is 10 plus the width
Answer: The answer choice I concluded from this problem was, letter [tex]\textbf{B” The expression 10w+2w shows the length of is 10 times the width”}[/tex]
Step-by-step: Hope this helps <3
Answer and Step-by-step explanation:
D is the correct answer.
This is because we see that there are two 5w, and two w
So 2(5w) represents two of the sides combined, and 2w represents two of the other sides combined (the length and width respectively).
The length 5w represents One side, and the width w represents the other side.
This correlates to the answer, which says that the length is 5 times the width, which it is since we see that there is a 5 times w, which w is the width.
A is also correct.
12w is all of the sides added together. 5w + 5w = 10, + w + w equals 12w. 12w is the perimeter.
B, C, and E are incorrect.
B says that the length is 10 times the width, which isn't true. In this situation, the length is 10 times 2w, or 10 times twice the width.
C says 5 times (w + w + w + w + w), which isn't true. If we distributed 5, we would get 5w + 5w + 5w + 5w + 5w, which would equal 25w, which is NOT the perimeter.
E says that 10 + w is the perimeter, which isn't true. We know the perimeter is 12w, so 10 + w can't be what the perimeter is.

Shelby paid $1.75 for a notebook at a big 75% off sale. What was the original price of the notebook?
Answer:
$7.00
Step-by-step explanation:
The discount is 75% off. To answer this question, multiply n (the original price) by (1.00 - 0.75): 0.25n = $1.75.
Solving this for n, we get $7.00

What are functions?A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively. Initially, functions represented the idealized relationship between two changing quantities.
Given
f(x) = - x² + 6x -1
g(x)=3x² - 4x - 1
(f-g)(x) = - x² + 6x -1 -(3x² - 4x - 1)
(f-g)(x) = - x² + 6x -1 - 3x² + 4x + 1
(f-g)(x) = - 4x² + 10x
(f-g)(x) = - 4x²+ 10x

Convert €90.50 to pounds give your answer rounded to 2 DP
Answer: £67.88
Step-by-step explanation:
From the estimation, we are informed that £3 = €4. This means that:
£1 = €4/3
Therefore, to convert €90.50 to pounds will then be:
= 90.50 ÷ 4/3
= 90.50 × 3/4
= 90.50 × 0.75
= 67.875

The value of x is 42 of three parallel lines intersected by two transversal lines
To solve for x in the given scenario of three parallel lines intersected by two transversal lines, we'll first determine the relationship between the corresponding angles.
According to the properties of parallel lines, corresponding angles are congruent. Thus, if we have an equation involving the corresponding angles, we can solve for x.
In this case, we have the equation:
x/35 = 30/25
To solve for x, we can cross-multiply:
25x = 30 * 35
25x = 1050
Dividing both sides by 25:
x = 1050/25
x = 42
Therefore, in the given scenario, the value of x is 42.

what is the correct expanded form and value of (1 over 5 ) 4
Answer:
1/625
Step-by-step explanation:
y=-3x + 10
y = -2x + 6
Substitution method
Answer:
x=4 and y=−2
Step-by-step explanation:
y=−3x+10;y=−2x+6
Step: Solve y=−3x+10for y:
Step: Substitute−3x+10foryiny=−2x+6:
y=−2x+6
−3x+10=−2x+6
−3x+10+2x=−2x+6+2x(Add 2x to both sides)
−x+10=6
−x+10+−10=6+−10(Add -10 to both sides)
−x=−4
-x/-1 = -4/-1 (Divide both sides by -1)
x=4
Step: Substitute4forxiny=−3x+10:
y=−3x+10
y=(−3)(4)+10
y=−2(Simplify both sides of the equation)
Answer:
Solution is the point (4, -2)
Step-by-step explanation:
use the expression for y from the first equation in the second equation:
then the equation y = - 2 x + 6 becomes:
- 3 x + 10 = - 2 x + 6
add 3 x to both sides
10 = 3 x - 2 x + 6
10 = x + 6
subtract 6 from both sides
x = 4
Now replace x with 4 in the first equation to find y:
y = - 3 x + 10 = - 3 (4) + 10 = - 12 + 10 = -2
Therefore this is the point solution to the system:
(4, -2)
please help me ASAP thank you
101+ 6x-5=180
6x=84
x=14
hope this helps!
Answer:
x = 14
Step-by-step explanation:
Since m || n, the two adjacent angles (101° and (6x-5)) must add up to 180°.
180° - 101° = 79°. Therefore, 6x - 5 = 79.
Add 5 to both sides, and the equation is 6x = 84.
Then divide both sides by 6 to get x = 14.
