Graph the function need ASAP help
Is it a, b , c or d?
Answer:
D
Step-by-step explanation:
(the line is a / shape, so the slope is positive)
(the line crosses the y axis at (0,-2)
(using the above information, the equation is y=2x-2)
Answer:
y = 2x - 2
Step-by-step explanation:
Start with
y = mx + b
The graph shows the y-intercept -2.
We have y = mx - 2
slope = m = rise/run
The slope is rise of 2 and run of 1, so m = 2.
y = 2x - 2
Please help explanation if possible
Answer:
y = 4x-31
Step-by-step explanation:
parallel lines, slope is the same.
two ways to solve it,
y=4x+c
sub y = -11. x =5
-11 = 4(5) + c
c = -31
OR
y-(-11) = 4(x-5)
y+11=4x-20
y=4x-20-11
y=4x-31
Answer:
The equation is y = 4x - 31
Step-by-step explanation:
y - y1 = m (x - x1)
y - (-11) = 4 (x - 5)
y + 11 = 4x - 20
y = 4x - 20 -11
y = 4x - 31

Mary spent $15. If this was 20% of her earrings, how much money did she earned?
Hi, I'm happy to help!
First off, we need to arrange an equation for what is being asked. 15 is 20% of her earnings and we don't know her total earnings.
15=20%×__
We can write this percentage as
15=0.2×__
We then change the equation to do the inverse operation, which is division, this makes it easier to solve.
15÷0.2=__
Now, we solve
15÷0.2=75
She earned $75
I hope this was helpful, keep learning! :D

Bao Yu is completing the square to solve the polynomial equation.
x2 – x – 3 = 0
What should be her first step?
adding –x to both sides of the equation
adding –3 to both sides of the equation
isolating the first term, x2
isolating the constant, –3
[tex]\\ \sf\longmapsto {x}^{2} - x - 3 = 0 \\ \\ \sf\longmapsto {x}^{2} - x = 3 \\ \\ \sf\longmapsto 4( {x}^{2} - x) = 4 \times 3 \\ \\ \sf\longmapsto 4 {x}^{2} - 4x = 12 \\ \\ \sf\longmapsto {(2x)}^{2} - 2 \times 2x \times 1 = 12 \\ \\ \sf\longmapsto {(2x)}^{2} - 2 \times 2x \times 1 + {1}^{2} = 12 + 1 {}^{2} \\ \\ \sf\longmapsto {(2x - 1)}^{2} = 12 + 1 \\ \\ \sf\longmapsto {(2x - 1)}^{2} = 13 \\ \\ \sf\longmapsto 2x - 1 = \pm \sqrt{13} \\ \\ \sf\longmapsto 2x = 1 \pm \sqrt{13} \\ \\ \sf\longmapsto x = \frac{1 \pm \sqrt{13} }{2} [/tex]
Bao Yu first step to solve the equation is,
⇒ adding –3 to both sides of the equation
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The polynomial is,
⇒ x² - x - 3 = 0
Now,
We can solve the equation as;
⇒ x² - x - 3 = 0
⇒ x² - x - 3 + 3 = 3
⇒ x² - x = 3
⇒ x² - x + 1/4 = 3 + 1/4
⇒ (x - 1/2)² = 13/4
⇒ x - 1/2 = ±√13 / 2
⇒ x = ±√13 / 2 + 1/2
Hence, Bao Yu first step to solve the equation is,
⇒ adding –3 to both sides of the equation

Step-by-step explanation:
Since AC is a tangent and PB is the raduis
[tex]\angle PBC= 9[/tex]
By pythagoras
[tex]PC^{2} =PB^{2} +BC^{2}[/tex]
[tex]41^{2} =9^{2} +BC^{2}[/tex]
[tex]1681-81=BC^{2}[/tex]
[tex]1600=BC^{2}[/tex]
[tex]BC=\sqrt{1600}[/tex]
[tex]BC=40[/tex]
OAmalOHopeO
Answer:
40
Step-by-step explanation:
A tangent to a circle is perpendicular to the radius intersection by definition. That makes BPC a right triangle at B. BP and PD are both equal (9) because every radius of a circle is equal. So
PC**2 = BP**2 + BC**2 or
41**2 = 9**2 + BC**2
1681 = 81 + BC**2
1681 - 81 = BC**2
1600 = BC**2
40 = BC

What is the inverse of the function y = -8x + 15?
A. y = 1/8x + 15
B. y = -8x - 15
C. y = (x - 15)/-8
D. y' '= -1/8x + 1/15
Answer:
c) ( x-15)/-8
Step-by-step explanation:
c) (x-15) / -8
Answer:
Solution given:
y = -8x + 15
interchanging role of x and y
we get
x=-8y+15
solve for y
x-15=-8y
divide both side by-8
we get
-8y/-8=(x-15)/-8
y=(x-15)/-8
:.
C. y = (x - 15)/-8 is a required inverse.

a man sells an article at rupees 600 and makes a profit of 20% of selling price calculate is profit percentage
Answer:
25%
Step-by-step explanation:
profit percentage = (profit/cost price) * 100
selling price = 600
profit = 600 * 20/100 = 120
cost price = 600-120 =480
profit percentage = (120/480) * 100 = 25
