Factor the following expression: 14b + 7a.
Answer:
7(a+2b)
Step-by-step explanation:
To factor an expression, you want to find the greatest common factor (GCF). I know that 7 can go into both 14 and 7, so my GCF would be 7. If I divide both 7a and 14b by 7, I get a and 2b. This means that my answer would be 7(a+2b) as that simplifies to 7a+14b. Hope that was helpful!
Answer:
2(7b + a)
Step-by-step explanation:
to factorize u should take the hcf of both number and put it outside the bracket. if u solve it u can see that 2(7b + a) also equals to 14b + 7a when u use distributive property

Write the equation of the line passing through the given points (-4,2) (-4,7)
Answer:
Step-by-step explanation:
The x value is always going to be - 4. The y value will vary quite a bit.
x + 4 = 0 is the equation of the line. The slope is undefined. There is no y intercept. There is an x intercept; it is minus 4.
If k is the midpoint of, jk=11x-7 and kl=6x+2, find jl
Answer:
JL = 118/5
Step-by-step explanation:
Because K is the midpoint, we know that JK and KL are going to equal each other because of the Segment Addition Postulate.
JK + KL = JL
So we know that JK = 11x-7 and KL = 6x+2
Now, we solve for X.
11x-7 = 6x+2
In order to get X alone, we must get the X's all to one side and the numbers to one side.
11x-7 = 6x+2
+7 +7
11x = 6x + 9
-6x -6x
5x = 9
x = 9/5
Now, we plug X into the equations.
JK = 11x - 7
JK = 11(9/5) - 7
JK = 99/5 - 7
JK = 64/5
KL = 6x + 2
KL = 6(9/5) + 2
KL = 54/5
Now, we add the numbers (fractions, really) together so that we can get the whole value of the line.
64/5 + 54/5 = 118/5
After swimming 60 feet below the surface of water, a whale swims up 30 feet. Use a number line to help you create an equation that shows the new location of the whale in relation to the water service.
A. The equation is -60 + (-30) = -90. The whale is 90 feet below the waters surface.
B. The equation is -60 + (-30) = -30. The whale is 30 feet below the water surface.
C. The equation is -60 + 30 = -30. The whale is 30 feet below the water surface.
D. The equation is -60 + 30 = -90. The whale is 90 feet below the water surface.
Answer:
C. The equation is -60 + 30 = -30. The whale is 30 feet below the water surface
Step-by-step explanation:
At the surface of the water in the swimming pool, the height of elevation is 0.
Thus, if you swim 60 ft below the surface, it means you are going in the negative direction when we consider a number line. Thus, distance = -60 ft
Now, when you swim back up by 30 ft, it is in the positive direction. Thus, total distance is now; -60 + 30 = -30 ft
Thus value denotes a negative direction and it means you are 30 ft below the surface of the water.
A sequence has an initial term a1=22 and a recursive formula an=an−1−10.

The correct options are a and d.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given:
The value of X increased by 35%.
Here, we will use the percentage formula.
The value is increased by 35%.
That means,
100 + 35 = 135%
135% in decimal form is 1.35.
In expression form as subject to X,
X(1.35)
In expressed form,
= X + 0.35X
= 1.35X
Therefore, equivalent expressions are 1.35X and (1+0.35)x.

slove the equation below for y :
6x-4y=12
Answer:
[tex]y=-\frac{3(x +2)}{2}[/tex]
Step-by-step explanation:
We have an equation, and the question is asking for us to solve y. So to solve, we have to isolate y.
6x - 4y = 12
Subtract 6x from both sides :
-4y = 12 - 6x
Divide both sides by -4 :
[tex]y=-\frac{3(x+2)}{2}[/tex]

[tex]\frac{dy}{dx} = (x+3)^{4} (7)(x-5)^{6} + (x-5)^{7} (4)(x+3)^{3}[/tex]
The values of x are x = -3 ,5 and [tex]x = \frac{-1}{11}[/tex]
Step-by-step explanation:
Step(i):-
Given that the function
y = (x+3)⁴(x-5)⁷ ...(i)
Apply UV formula
[tex]\frac{dy}{dx} = U^{l} V+ U V^{l}[/tex]
Differentiating equation (i) with respective to 'x ', we get
[tex]\frac{dy}{dx} = (x+3)^{4} (7)(x-5)^{6} + (x-5)^{7} (4)(x+3)^{3}[/tex]
Step(ii):-
Given that
[tex]\frac{dy}{dx} = 0[/tex]
[tex](x+3)^{4} (7)(x-5)^{6} + (x-5)^{7} (4)(x+3)^{3} =0[/tex]
[tex](x+3)^{3}(x-5)^{6} (7(x+3)+4(x-5))[/tex] =0

(4ad) - 16/169c -1.
Step-by-step explanation:
Alright. Let's start.
(4ad) - [tex]\frac{1}{13}[/tex]b * [tex]\frac{16a}{13abc}[/tex] -1 is the expression.
So, by PEMDAS, we need to do the multiplication first. We can also say that 1/13b is the same as b/13.
(4ad) - 16ab/169abc -1 Now let's cancel out the b and a on numerator and denominator.
(4ad) - 16/169c -1.

Ana es una vendedora de bombones tenía 295 cajas y ha vendido 67 de ellas si cada caja contiene 24 bombones¿ cuántos bombones le quedaron sin vender?
Answer:
the number of chocolates remains unsold is 5,472
Step-by-step explanation:
The computation of the number of chocolates remains unsold is given below:
= (Total boxes - sold boxes) × number of chocolates in each box
= (295 - 67) × 24
= 228 × 24
= 5,472 chocolates
hence, the number of chocolates remains unsold is 5,472
1) A puppy eats a sausage 5 seconds faster than a kitten eats an identical sausage. If they share one sausage, they can eat it in 6 seconds. How long does it take each animal to eat a sausage alone?
2) A tourist ignores the warning signs and leaves food in his car while he goes for a hike. A mama bear and her cub open the car door in 6 seconds. How long would it take each bear to open the car door alone if the cub needs 9 more seconds than the mama bear?
3) A superhero and his sidekick simultaneously leave the city and fly toward a secret hideout that is 1800 km away. The superhero's speed is 100 km/h slower than the sidekick's speed, and so he arrives at the hideout 36 minutes after his sidekick. Find the speed of each.
4) A bear loves visiting his friend, the piglet. The distance between their houses is 300m, and the bear always walks from his house to the piglet's house in exactly the same amount of time. But today, the bear stops at a beehive after walking 1/4 of the distance. He eats honey for 2.5 minutes and then continues to the piglet's house at a speed 15 m/min faster than usual. The total journey to the piglet's house takes the exact same amount of time as it usually does, when the bear does not stop for honey. How long does the journey take?
Answer:
1) The puppy takes 10 minutes, the kitty takes 15 minutes.
2) The mama bear takes 9 minutes, the cub takes 18 minutes
3) The sidekick goes at 600 mph, the hero goes at 500 mph.
4) 10 Minutes
5) RSM is so hard, amiright?
Step-by-step explanation:
1) You can simplify the word problem into the equation 1/x + 1/x+5 = 1/6. For problems like these, you have to simplify the last part to a fraction, not a whole number. Then you just solve.
2) Same thing. 1/x + 1/x+9 = 1/6. Solve. Boom. Done.
3) A bit different, but it simplifies to 1800/x-100 - 1800/x = .6. Solve. C'mon, you should've been able to do this one.
4) Harder, simplifies to 75/x+225/x+15+2.5 = 300/x. You get the last part because the time the bear took is equal to the time it would normally take, which is the entire distance over the normal pace. Then you solve and there we go, most of your RSM homework is done.
