help me plz bc i don't understand this and this is from 2 weeks ago and I have straight F's in school
Answer:
y = -3x + 3
Step-by-step explanation:
So, basically I can't remember how to do this the long way but I used a calculator on Desmos (the graphing one to be specific). You should be able to find tutorials on how to use it and graph problems to find their answers but if not, you can just message me and I'll walk you through how to use it.
As for the form it asked for in the question, slope-intercept form is just:
y = mx + b
m is the slope, and b is the y-intercept (the place where the line crosses the y-axis)
what does rotation about (-3,-4) mean
Answer:
Step-by-step explanation:
Depends on what kind of rotation you would be doing. But for example, if you are rotating 90 degrees about a point on a graph, your point (x, y) changes to (-y, x). Then another 90 degrees would be (-x, -y).
Help please!!! Which graph represents a system of equations with NO SOLUTION. Explain how you know.
Answer:graph B
Step-by-step explanation:because if a line is parallel they have no solutions with a certain slope
If two lines intersect then they must have at least a solution
5(2a-6b+8)
Please helppp
Answer:
10a - 30b + 40
Step-by-step explanation:
Multiply each term inside the ( ) by the 5 outside the ( ).
5 x 2a = 10a
5 x -6b = -30b
5 x 8 = 40
Add the terms together (don't forget that it's negative 30b)
10a + -30b + 40 = 10a - 30b + 40

-4x + 16 = y
2x - 32 = 2y
Step 2: Solve for x
Substitution
Substitute in y: 2x - 32 = 2(-4x + 16)Distribute 2: 2x - 32 = -8x + 32[Addition Property of Equality] Add 8x on both sides: 10x - 32 = 32[Addition Property of Equality] Add 32 on both sides: 10x = 64[Division Property of Equality] Divide 10 on both sides: x = 32/5Step 3: Solve for y
Define original equation: -4x + 16 = ySubstitute in x: -4(32/5) + 16 = yMultiply: -128/5 + 16 = yAdd: -48/5 = yRewrite/Rearrange: y = -48/5The perimeter of a triangle is 26 feet. The second side is twice as long as the first. the third side is 1 foot longer than the second side. What is the length of the 3 sides?
Answer:
5, 10 and 11 feet.
Step-by-step explanation:
Let length of first side be x feet then
second side = 2x feet
third side = 2x + 1 feet.
So we have the equation:
x + 2x + 2x + 1 = 26
5x + 1 = 26
5x = 25
x = 5 feet.
So first side = = 5 feet, second = 10 and third = 11 feet.

What fratcion is equal to 50% of 1 third
Answer:
1/6
Step-by-step explanation:
To know what fraction is equal to 50% of 1/3, we have to convert the percentage into a fraction first.
50% = 50/100
So 50% of 1/3 = 1/3 * 50/100
= 50/ 300
= 5/30
= 1/6
Answer:
1/6

Plentiful Pies determines its annual profits
in dollars using p(x) = 65x - 0.3x2 where x
represents the numbers of pies sold. If Plentiful
Pies sells 175 pies in a year, what will their
annual profits be?
Answer:
The annual profits will be 2187.5
Step-by-step explanation:
p(x) = 65x - 0.3x^2
I am guessing that the 2 was supposed to be a square.
Simply plug in the number of pies sold:
p(175) = 65(175) - 0.3(175)^2 = 11375 - 0.3*30625 = 11375 - 9187.5 = 2187.5
The diameter of a circle has endpoints of (2, 5) and (-4, 13). What is the correct equation of this circle? Pls explain and I will mark brainliest!
Answer:
Option 4Step-by-step explanation:
Midpoint of the diameter is the center.
Use midpoint formula to determine the coordinates:
x = (2 - 4)/2 = -1y = (5 + 13)/2 = 9Find the radius using the midpoint and one of the endpoints and the distance formula:
r = [tex]\sqrt{(-1 - 2)^2 + (9 - 5)^2} = \sqrt{9+16} = \sqrt{25} = 5[/tex]Use the equation of the circle:
(x - (-1))² + (y - 9)² = 5²(x + 1)² + (y - 9)² = 25Correct choice is 4
What is the equation of the line that passes through the point (-5, 7) and
has a slope of - 1/5?
Answer:
[tex]y=-\frac{1}{5}x+6[/tex]
Step-by-step explanation:
We have the following equation
y=mx+b
where m is the slope
and b is the y intercept
we know that the slope is -1/5 (or -.2)
which means that so far our equation looks like this
y= -.2x+b
which means we need to solve for b
we know that when x= -5 y= 7 which means we can plug in those values and solve for b
we have
7= (-.2*-5)+b
7=1+b
b=6
which means our equation is as follows
y= -1/5x+6

Algebra 1 need help (Solving exponents equations)
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the exponents and indices.
here, we should remember one thing that,
3 ^3 = 27 and 1/3^x = 3^-x
so we get as,
(3^-3)^4-x = (3^3)^2x-1
==> 3^-12+3x = 3^6x-3
since the base is same that is 3 , we equate their powers.
-12x+3=6x-3
==> 3+3 = 6x+12x
==> 6 = 18x
hence ===> x = 6/18 = 1/3
hence, x = 1/3

5 and2/3 divide by 4?
Answer:
The answer is 1 5/12 or 17/12.
Step-by-step explanation:
First we turn 5 2/3 into a Improper fraction.
5 2/3 = 17/3
Next we change 4 to 1/4 then multiply 1/4 by 17/3.
17/3 * 1/4 = 17/12
17/12 = 1 5/12
Hope this helps! :)
Answer:
17/12
