If f(x) = - 4x + 3 and g(x) = 3 x2 + 2x - 4, find (f+ g)(x).

Answer:

No

Step-by-step explanation:

No, because the perimeter of a rectangle is 2(x+y). Justin added the sides. Then he should have multiplied by 2 but he didn't so Justin is incorrect.    

Hope this helps plz mark brainliest :D

Answer:

No, his answer should have been 6x+2

Step-by-step explanation:

The equation for perimeter is 2L+ 2W=P

so 2 (2x-3) + 2 (x+4) = 6x+2

Answer:

y=mx+b

Step-by-step explanation:

Answer:

y=mx+b

Explanation:

The slope-intercept formula is y=mx+b. The b represents the y-intercept, which is the point where a line on a graph meets the y-axis. The coordinates for this would be (0,b). The m represents the slope, which is the rate of change. The x represents any x variable that you plug in. The y represents the y variable.

Answer: I think its Consine

Step-by-step explanation:

Answer:

y=5

Step-by-step explanation:

That is literally what horizontal lines' equations would be like.

The slope would be 0, so y=0x and the y-intercept would be 5 so y=0x+5 which is useless to keep the 0x so it becomes y=5.

Answer:

I think the answer is y=5

Answer:

x=20

Step-by-step explanation:

7+0.20x=5+0.30x              

then take the 7 and subtracet the 2 from it, then take the 0.30 and subtract the 0.20 from it then you should get 2=0.10x      

then to get rid of the 0.10 you take it and divide it from the 2 which gives you 20 then you have 20=x and thats your answer

Answer:

whats the question?????

Step-by-step explanation:

Answer:

6 for $24.96

Step-by-step explanation:

$5.90 * 3 = $17.70

Therefore 4 books would be $17.70 because you get one for free

$24.96/6 = $4.16

Therefore if you got 4 books it would be $16.64

So, buying 6 books would be cheaper.

This is my other acount that I just made

Step-by-step explanation:

Answer:

Yes, congruent by SAS

Step-by-step explanation:

We already know two sides and two angles are congruent, and since the triangles share the same congruent side with an angle in between both pairs of congruent sides, then yes it is congruent by SAS.

Answer:

1. 115; obtuse

2. 130; obtuse

3. 50; acute

4. 108; obtuse

Step-by-step explanation:

m<1 = 115, corresponding

m<2 = 130, alternate exterior angles

m<4 = 50, alternate interior angles

m<1 = 108, supplementary

Answer:

A. 6

Step-by-step explanation:

The reciprocal is the fraction flipped

1/6 would become 6/1

6/1 is basically 6

(You said the opposite reciprocal so I don't know if you meant the oppisite of the reciprocal but. . . . oh well. If you did mean that, then the answer would be C. 1/6)

Hope this helps :)

Answer:

11.39

Step-by-step explanation:

Have a great day! :)

Answer:

m= -1/2

Step-by-step explanation:

Answer:

the amount of water she drinks is x, the mileage is y:

   x          y          

2 miles     5 oz

4 miles     10 oz

6 miles     15 oz

the ratios would be 4/10 and 6/15

Step-by-step explanation:

for every 2 miles Holly runs, she drinks 5 oz of water, right? the ratio is 5:2, so if you were to come up with other numbers that match the ratio, they have to be divisible by the parts of the ratio. so if she runs 2 miles, she drinks 5 oz. if she runs 4 miles, then she drinks 10 oz.

think of a ratio like a fraction (in this case it would be 2/5). if you were to make equivalent ratios, then the two fractions would have to be equal, right? well, when you simplify all of the numbers listed in the table above after making them into fractions, they would all go back to 2/5, so the numbers i came up with above are equivalent ratios, meaning they have the same value when simplified.

hopefully that helps and isn't too confusing! if you need other help, let me know! :)  

Answer:

I am pretty sure it is 10.5

Step-by-step explanation:

Answer:

10.5

Step-by-step explanation:

your equation: DT = DH + HT

HT = 2DH

so now your equation is DT = DH + 2DH

plug in your values: 3.5 + 2(3.5)

you get DH = 10.5

Answer:

I will answer in English, you can translate it after, as this is math, will be easier to read.

This can be translated to:

Present the fraction:

a) - 7/9 as a fraction with 27 denominator

b) 7/17 as a fraction with 102 denominator

c) 13/16 as a fraction with 80 denominator

d) 11/13 as a fraction with 78 denominator

a) We can multiply both numerator and denominator by the same number, and the quotient remains the same:

We know that 9*3 = 27

then: (-7/9)*(3/3) = -21/27

b) Here we can use that 102 = 17*6

Then we multiply the numerator and denominator by 6:

(7/17)*(6/6) = 42/102.

c) We can use that 16*5 = 80.

Then we should multiply both denominator and numerator by 5.

(13/16)*(5/5) = 65/80

d) We can use that 6*13 = 78, then we can multiply both denominator and numerator by 6.

(11/13)*(6/6) = 66/78
