Whatever the highest exponent is determines the degree.
9e + 4=-5e + 14 + 13e
Answer:
e= -10/9
Step-by-step explanation:
Answer:
e = 10
Step-by-step explanation:
1.) We need to manipulate the equation to get e by itself.
2.) To solve the equation, do the following steps;
9e + 4 = −5e + 14 + 13e
9e + 4 = 14 + 8e (Combine like terms)
9e + 4 − 8e = 14 + 8e − 8e (Subtract 8e from each side)
e + 4 = 14 (Combine like terms)
e + 4 - 4 = 14 - 4 (Subtract 4 from each side)
e = 10 (Combine like terms.
3.) Answer: e = 10.
Now lets check our work. To check your work, do the following steps;
9e + 4 = −5e + 14 + 13e
9e + 4 = 14 + 8e
9(10) + 4 = 14 + 8(10)
90 + 4 = 14 + 80
94 = 94
By doing those steps we can confirm the answer, e = 10, is true.
Write an equation in slope intercept form (y=max+b) for the line passing through the points. Show your algebraic solving steps.
(-2, -1) and (2,3)
Find the gradient first
m = (y2-y1)/(x2-x1) = 3-(-1)/2 - (-2) = 4/4 = 1
then find the equation of the... slope ._.
y - y1 = m(x - x1)
y - (-2) = 1(x - 3)
y + 2 = x - 3
y =x -3 - 2
y = x - 5
So the equation is y = x - 5
find the product of (x-3)^2
Answer:
x^2 - 6x + 9
Step-by-step explanation:
(x-3)^2
(x-3)(x-3)
x^2 -3x -3x + 9
x^2 - 6x + 9
^2 means (x - 3) times itself twice.
(x - 3)(x - 3) multiplying polynomials- Firsts, Outs, Inners, Lasts (FOIL)
Firsts (x* x) Outs (x*-3) Inners (-3 * x) Lasts (-3*-3)
xx -3x -3x +9 Combine like terms.
-3x -3x Adding/subtracting integers- same signs means you add
and keep the sign.
x^2 -6x + 9
Calcuate the 2 unit rates for the following 150 gallons in 50 seconds. this answer has 2 answers. please help the teacher is going to ask me for this question!!!
If f(1) = 9 and f(n) = 4f(n − 1) then find the value of f(4).
Answer:
576
Step-by-step explanation:
f(2) = 4f(1) = 4*9 = 36
f(3) = 4f(2) = 4 * 36 = 144
f(3) = 4f(3) = 4 * 144 = 576
if you could anwser the second question that would be great caus e i only get to do this proble once :) no explanation needed
Angle 1 and 2 are equal because of correspondence angle
so , (78-2x) = (89-3x)
x = 89 - 78
x = 11
hence angle 1 = ( 78 - 2*11) = 56
and angle 2 = ( 89-3*11) = 56
So, both of angle is 56
hope it help and your day will full of happiness

Answer:
yearly cost for housing expenses = $11,400, average monthly cost for food = $650
yearly clothing cost = $900,
average monthly cost for transportation= $500,
Yearly cost for insurance & medical= $14,400
yearly cost for emergency fund = $600
average monthly college saving = $50
Step-by-step explanation:
Yearly housing = monthly cost * 12 = 950 * 12 = 11400
Food, monthly = 7800 /12 = 650
Clothing, yearly = 75 * 12 = $900
Monthly transport = 6000 / 12 = $500
Insurance and medical = 1200*12 =14400
Emergency fund = $50 * 12 = $600
College saving = $600 / 12 = $50

2/3x + 1/4 = 46/6x - 1/3
Answer:
x = 1/12
Step-by-step explanation:
2/3x + 1/4 = (8x+3) /12 (create equivalent fractions with a denominator of 12)
23/3x - 1/3 = (23x - 1) /3 *(46/6x = 23/3x)
8x + 3 = 23x - 1
12 3
now cross-multiply:
3(8x + 3) = 12(23x - 1)
24x + 9 = 273x - 12
9 = 252x - 12
21 = 252x
x = 21/252 which reduces to 1/12

7. What is the slope of the line that passes through the points (14, -18) and (5, -12)?
Answer:
slope =[tex]-\frac{2}{3}[/tex]
Step-by-step explanation:
Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex] to find the slope, or [tex]m[/tex]. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point, and the [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point. So, substitute the x and y values of the points (14, -18) and (5, -12) into the formula and solve:
[tex]m = \frac{(-12)-(-18)}{(5)-(14)}\\m = \frac{-12+18}{5-14}\\m = \frac{6}{-9} \\m = -\frac{2}{3}[/tex]
Thus, the slope is [tex]-\frac{2}{3}[/tex].

common factor
Answer:
Greatest common factor of 17
So, the prime factors of 45 are 3, 3, and 5. The Greatest Common Factor is the greatest number that is common (that is, in both lists). It is 17. Since 17 is a factor of itself and of 51 -- which is 3 x 17 -- then the greatest possible common factor is 17!
Step-by-step explanation:
Add and subtract the second term to the expression and factor by grouping.
- (m - 1 )( 7m + 17 )

Camille's birthday party will cost $32 if she invites 16 guests. How many guests can there be, at most, if Camille can afford to spend a total of $48 on her birthday party? Assume the relationship is directly proportional.
Answer:
I think its gon be 24 guests
Answer:
24 people can be there at most :)
Step-by-step explanation:
$32 divided by 16(guests) is $2
so its $2 per person
so 48$ divided by $2 is 24
So Camille can invite 24 people at the cost of 48$ being her total at most :)

2-(3x+5)=5-2x
i have too answers but need the right one lol
Answer:
x = -8
Step-by-step explanation:
2 - (3x + 5) = 5 - 2x
Subtract 2 from each side.
-(3x + 5) = 3 - 2x
Apply the negative sign in front of the parentheses.
-3x - 5 = 3 - 2x
Add 5 to both sides.
-3x = 8 - 2x
Add 2x to both sides.
-x = 8
We can't have a negative x value, so we'll need to multiply each side by -1.
x = -8
Hopefully, this helped and wasn't too confusing!
Answer:
Solution given;
2-(3x+5)=5-2x
2-3x-5=5-2x
-3-5=3x-2x
x=-8 is your answer
