Answer:

38

Step-by-step explanation:

To find the value of 7x^2 + 3x + 4 when x=2. We have to plug in x. So plugging x in, we have

7(2)^2 +3(2) +4

and this becomes

7(4) + 6 +4

or

8(4)+6

which is 38

What is <br> A= 3000(1+.036/12)^72<br> Algebra 2 compound interest
mihalych1998 [28]

First we need to simplify \frac{.036}{12} to 0.003.

We get 3000(1+0.003)^{72}

Now we simplify 1+0.0031+0.003 to 1.0031.003.

3000×1.003^{72}

Simplify {1.003}^{72}1.003 to 1.2407011.240701.

3000×1.240701

Then we simplify to <u>3722.103387.</u>

Hi, can you please solve that fast?​
Elenna [48]

Answer:

A.

Step-by-step explanation:

4 < 6t + 1 ≤ 43 (Given)

3 < 6t ≤ 42 (Subtracted 1 on both sides)

1/2 < t ≤ 7 (Divided 6 on both sides)

You are looking for an open dot on 1/2 and a shaded dot on 7 with a line between them. Therefore, the answer is A.

!!!I WILL MARK BRAINLIEST! PLZ ANSWER ASAP AND EXPLAIN! VERY IMPORTANT!!
Nata [24]

Answer: Check explanation

Step-by-step explanation: (3,-5), because that's the point where the two lines intersect.

Y=-2x+1

Y=-3/2x-1/2

Substitute the Y to get -2x+1=-3/2x-1/2

1/2x=3/2

x = 3

Now plug x into first equation: y=-2*3+1=-5

so the intersection point is (3,-5)
