9(r - 5)(r - 1)
Step-by-step explanation:
9r^2 - 36r - 45
First, factor out 9
9(r^2 - 4r - 5)
Then you can factor what's inside the parentheses
9(r - 5)(r -1 )
help please!!! i’ll give brainiest!
=================================================
Explanation:
Replace every x with -3
Then use the order of operations (PEMDAS) to simplify
y = -2x^2 + x - 5
y = -2(-3)^2 + (-3) - 5 ... x replaced with -3
y = -2(9) - 3 - 5
y = -18 - 3 - 5
y = -21 - 5
y = -26
Answer:
-26
Step-by-step explanation:
1. plug in -3 for all x's
-2(-3)^2 + (-3) -5
2. combine like terms
-2(-3)^2 - 8
3. pEmdas. deal with exponent first (remember: only affect the 3, since it's in parentheses! also when you square a negative number, it becomes positive!)
-2(9) - 8
4. peMdas. multiply -2 and 9 next.
-18 - 8
5. pemdaS. subtract 8 from -18.
-18 - 8 = -26

Dillon deposited 3/4 of his paycheck into the bank. If he deposited $46.50 into his bank account, what was the amount of the paycheck?
Answer:
$62
Step-by-step explanation:
Take $46.50 and divide it by 3 to get 1/4 of the paycheck
46.50/3 = 15.50
Then multiply 15.50 by 4 to get the whole pay check
15.50 x 4 = 62
Casey is using a recipe that requires 23cups of flour for every 2 cups of milk. If Casey uses 5 cups of milk, how many cups of flour are needed?

Find the distance between the two points in simplest radical form.
(0, –4) and (-3,-1)
Answer:
3[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (- 3, - 1)
d = [tex]\sqrt{(-3-0)^2+(-1+4)^2}[/tex]
= [tex]\sqrt{(-3)^2+3^2}[/tex]
= [tex]\sqrt{9+9}[/tex]
= [tex]\sqrt{18}[/tex]
= [tex]\sqrt{9(2)}[/tex]
= [tex]\sqrt{9}[/tex] × [tex]\sqrt{2}[/tex] = 3[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Hey there!
Given;
The points are;(0,-4) and (-3,-1).
Use formula for distance between the two points.
[tex]d = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } [/tex]
Put all values.
[tex]d = \sqrt{( { - 3 - 0)}^{2} + ( { - 1 + 4)}^{2} } [/tex]
Simplify to get answer.
[tex]d = \sqrt{9 + 9} [/tex]
[tex]d = \sqrt{18} [/tex]
[tex]d = 3 \sqrt{2} [/tex]
Therefore, the distance is 3√(2) units or 4.24 units.

How do you know if a girl like you and what is x+10 divided by 6 = 1
Answer:
x = -2/3
Step-by-step explanation:
x + 10 ÷ 6 = 1
Divide
x + 1 2/3 = 1
Subtract 1 2/3
x = -2/3
Also, as a girl, we do give some signs to people that we like, we start conversations with the person, we make eye contact and then look away (at least that what I do lol), flirts with you, agrees with you, wants to spend time with you, etc.
With the equation 3z+3=2z+6
Answer:
z = -3
Step-by-step explanation:
Simplifying
3z + -3 = 2z + -6
Reorder the terms:
-3 + 3z = 2z + -6
Reorder the terms:
-3 + 3z = -6 + 2z
Solving
-3 + 3z = -6 + 2z
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Add '-2z' to each side of the equation.
-3 + 3z + -2z = -6 + 2z + -2z
Combine like terms: 3z + -2z = 1z
-3 + 1z = -6 + 2z + -2z
Combine like terms: 2z + -2z = 0
-3 + 1z = -6 + 0
-3 + 1z = -6
Add '3' to each side of the equation.
-3 + 3 + 1z = -6 + 3
Combine like terms: -3 + 3 = 0
0 + 1z = -6 + 3
1z = -6 + 3
Combine like terms: -6 + 3 = -3
1z = -3
Divide each side by '1'.
z = -3
Simplifying
z = -3
Answer:
=3z+3=2z+6
=3z-2z=6-3
=z=3

Answer:
good luck
Step-by-step explanation:
Write an equation for the line that is parallel to the given line and passes through the given point . Write the equation of the line in y=mx+b form
y=5x-7;(2,-2)
A parallel line has the same slope as the original equation. Therefore, the slope (m in y=mx+b) will be 5. From there, we can use the point-slope formula and convert it into the slope-intercept formula (y=mx+b).
Point-slope is:
y-y₁=m(x-x₁)
Plug in our known values:
y-(-2)=5(x-(2))
Distribute and set it equal to y:
y+2=5x-10
y=5x-12

What is the equivalent ratio to the ratio 4:6.how do I know the ratio is equivalent?
Since you asked, simply, to know how a ratio is equivalent to another.
Ratios are like fractions in the way that they can be multiplied and simplified. 1:2, for example, can also be 10:20, 5:10, etc. This is inherent to the way a ratio works - say, for every 1 person, there are two cheese slices. This means that when the group gets larger, so does the amount of cheese slices.
Now, to find an equivalent ratio. You can simplify 4:6 by finding the GCF (greatest common factor) of these two numbers - something you can divide both of them by evenly. In this case, the GCF is 2. We divide both 'sides' by 2, and we get a simplified ratio of 2:3. You can then multiply this by different numbers (ones that are logical and could reasonably lead you to an answer on your worksheet or whatnot) until you find an equivalent ratio.

Answer:
they won 52 games
they lost 19 games
the equation is 2x + 33= 71
Step-by-step explanation:
they played 71 games in total
say the amount of games they won is y
say the amount of games they lost is x
using the variables, you can form this equation:
y + x = 71
you also know that they won 33 more games then they lost.
so, y = x + 33
now, you can substitute y for x + 33 in the original equation
x + x + 33 = 71
combine like terms
2x + 33 = 71
subtract 33 from both sides of the equation
2x + 33 - 33 = 71 - 33
2x = 71 - 33
2x = 38
divide both sides of the equation by 2
2x/2 = 38/2
x = 38/2
x = 19
they lost 19 games.
now substitute 19 for x in the equation
y = x + 33
y = 19 + 33
y = 52
they won 52 games

So I'm practicing writing Standard and Slope Intercept equations. Can anyone help me on writing both equations if the points are (3,5) and (0,0)?
Answer:
standard: 5x-3y=5
slope intercept: y=5/3x-5/3
Step-by-step explanation:
so standard form is: ax+by=c
(a must be positive)
slope intercept form is: y=mx+b
(m is the slope of the line that the two points form)
first, find the slope:
(y1-y2)/(x1-x2)
(5-0)/(3-0)
slope=5/3=m
to do slope intercept, b is the y-intercept
to find that plug in one of your pairs of numbers like so,
y=mx+b
0=5/3x+b
b=-5/3
now we have slope intercept form!!
y=5/3x-5/3
to do standard form:
first, take your slope intercept form; y=5/3x-5/3
then subtract 5/3x from both sides making:
-5/3x+y=-5/3
multiply everything by -3 to get rid of the fraction and the negative like so:
5x-3y=5
and boom! standard form!
I always prefer going from slope-intercept to standard because its easier but its your choice! I hope I helped you!! Please mark brainliest!! Have a supertastic day

You are about to graph the linear equation y=1/4x+8 but you need to determine the scale of the x and y axes first. Select the best option for a scale for both the x-axis and y-axis (one of each). A) x scale of -5 to 5 B) x scale of -15 to 15 C) y scale of 0 to 15 D) y scale of -30 to 30 (10 POINTS AND BRAINLIST IF RIGHT WILL REPORT WRONG ANSWERS)
Answer:
B) x scale of -15 to 15
C) y scale of 0 to 15
Step-by-step explanation:
The change in y-value is 1/4 of the change in x-value, and the y-intercept is 8. That means a y-scale of -30 to 30 would not be well-utilized over a small range of x. (It would take an x-range of about 200 to make much use of that y-scale.)
An appropriate y-scale is one that has 8 near its middle. The corresponding x-scale is then roughly ±4 times half the y-scale. The closest choices are ...
-15 ≤ x ≤ 15 . . . . choice B
0 ≤ y ≤ 15 . . . . . . choice C
