what is an equation of the line that passes through the points (6,5) and (7,7)
Answer:
The slope of the line is m = 2.
The y-intercept is (0,7).
The equation of the line in the slope-intercept form is y = 2 x - 7.
Step-by-step explanation:
The slope of a line passing through two points [tex]P = \left(x_{1}, y_{1}\right)[/tex] and [tex]Q = \left(x_{2}, y_{2}\right)[/tex]
is given by [tex]m=\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]
We have that [tex]x_{1} = 6[/tex] , [tex]y_{1} = 5y[/tex] , and [tex]y_{2} =7.[/tex]
Plug the given values into the formula for a slope: [tex]m=\frac{7-5}{7-6} =2[/tex].
Now, the y-intercept is [tex]b=y_{1} -mx_{1}[/tex] (or [tex]b =y_{2} -mx_{2}[/tex], the result is the same).
[tex]b=5-(2)*(6)=-7[/tex]
Finally, the equation of the line can be written in the form [tex]y=b+mx[/tex]:
[tex]y=2x-7[/tex]
Answer:
[tex]\Large\boxed{\sf{y=2x-7}}[/tex]Step-by-step explanation:
The slope formula is used to find the equation of the line that passes through the points in this problem.
SLOPE FORMULA:
[tex]\Longrightarrow: \sf{\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{RISE}{RUN} }[/tex]
y₂=7y₁=5x₂=7x₁=6[tex]\Longrightarrow: \sf{\dfrac{7-5}{7-6}=\dfrac{2}{1}=2 }[/tex]
Use the slope-intercept form.
SLOPE-INTERCEPT FORM:
[tex]\Longrightarrow: \sf{Y=MX+B}[/tex]
[tex]\Longrightarrow: \text{The M represents the "slope".}[/tex]
[tex]\Longrightarrow: \text{The B represents the "y-intercept".}[/tex]
y=2x-7Therefore, the slope is 2 and the y-intercept is 7.The correct answer is y=2x-7.I hope this helps. Let me know if you have any questions.

[tex]x^2 -3x -70\\\\=x^2 -10x +7x -70\\\\=x(x-10)+7(x-10)\\\\=(x+7)(x-10)[/tex]
Answer:
(x - 10)(x + 7).
Step-by-step explanation:
This is a quadratic expression and the factors are of the form (x + a)(x + b).
We have x^2 - 3x - 70.
- to find the values of a and b in this expression we need 2 numbers whose product is -70 and whose sum is -3.
They are -10 and +7 , so the factors are:
(x - 10)(x + 7).
Medical assistants are to receive a 9% increase in wages per hour. If they were making $16.75 an hour, what is the new wage per hour to the nearest cent?
A percentage is a way to describe a part of a whole. The new wage per hour to the nearest cent if it is increased by 9% will be $18.26.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that the Medical assistants are to receive a 9% increase in wages per hour. While the current wage of Medical assistance is $16.75 an hour.
Therefore, the new wage per hour to the nearest cent will be,
New wage = Old wage + 9% of old wage
= $16.75 + 0.09($16.75)
= $18.26
Hence, the new wage per hour to the nearest cent will be $18.26.

if z 2 square equal 49 what are the solutions
z = 7, z = -7
Calculations ↓z² = 49
Take the square root of both sides to find what z equals
z = 7
Is that the only solution? Is 7 the only number that can be multiplied by itself and have a result of 49? No, there's another number. This number is -7.
So the solutions are ↓7, -7

9. You are installing a swimming pool. Write a polynomial that represents the area of the walkway
8 ft width of the pool
(6x-4) ft length (of the pool)
(2x + 6) ft length of the Walk way
10x ft width of the Walk way
Answer:
(10x² +12x +32) ft²
Step-by-step explanation:
The area of the walkway around the pool is the difference between the area of the entire rectangle, and the area of the pool. The area of each rectangle is found by multiplying its length and width.
__
Overall area:
((2x +6) ft) × (10x) ft = (10x² +60x) ft²
Pool area:
((6x -4) ft) × (8 ft) = (48x -32) ft²
Walkway area:
overall area - pool area = ((10x² +60x) ft²) -((48x -32) ft²)
= (10x² +12x +32) ft²
