Dawn has two bank accounts she has been using to save money for a car. The difference between account A and account B is $100. If she uses StartFraction 3 Over 8 EndFraction of account A and StartFraction 7 Over 8 EndFraction of account B, Dawn will have a down payment of $2000. Choose the statements that are true when solving for the amount Dawn has in each account. Check all that apply.
One of the equations that represents this scenario is A – B = 100.
One of the equations that represents this scenario is StartFraction 3 Over 8 EndFractionA + StartFraction 7 Over 8 EndFractionB = 2000.
To eliminate the A variable, multiply the first equation by 3 and the second by 8.
To eliminate the B variable, multiply the first equation by 7 and the second by 8.
To eliminate the B variable, multiply the first equation by 7 and the second by –8.

3x + y - 3

Step-by-step explanation:

Like Terms: In algebra, like terms are terms that have the same variables and powers.

To simplify this expression and get an expression that is eual to 5x + 3y - 2x - 2y - 3 I used like terms :

(5x - 2x) + (3y - 2y)

(5x - 2x = 3x) + (3y - 2y = 1y or y)

3x + y

Then we add the - 3 at the end giving us:

3x + y - 3

Apply l'Hopital's rule:

[tex]\displaystyle\lim_{x\to\pi}\frac{\displaystyle\int_\pi^x (1+\tan(t))\,\mathrm dt}{\pi\sin(x)}=\lim_{x\to\pi}\frac{1+\tan(x)}{\pi\cos(x)}=\frac{1+\tan(\pi)}{\pi\cos(\pi)}=\boxed{-\frac1\pi}[/tex]

where

[tex]\displaystyle\frac{\mathrm d}{\mathrm dx}\left[\int_\pi^x(1+\tan(t))\,\mathrm dt\right]=1+\tan(x)[/tex]

follows from the fundamental theorem of calculus.

Answer:

x=y/12

Step-by-step explanation:

I took the variable and flipped it. Instead of solving for y inches, I solved for x feet.

We want to find the width of a rectangle, we will find that the width is 10 inches.

So we know that the perimeter of a rectangle is just given by:

P = 2*(L + W)

Where L is the length and W is the width.

Here we know that:

P = 24 inches

L = 2 inches

Replacing that we get:

24 in = 2*(2 in + W)

(24in)/2 = (2 in + W)

12 in = 2 in + W

12 in  - 2 in = 10 in = W

So the width is 10 inches.

Answer:

Option B: 4

Step-by-step explanation:

From the image, the correct function is;

f(x) = x³ -5x² - 8x + 48

Now, the x-intercept occurs when y = 0.

Thus;

x³ - 5x² - 8x + 48 = 0

So we are looking for values of x that will make y = 0.

Let's try the options;

Let's try x = -4;

(-4)³ - 5(-4)² - 8(-4) + 48 = -64 - 80 + 32 + 48 = -64 ≠ 0

So, x = -4 is not an x - intercept

Let's try x = 4;

(4)³ - 5(4)² - 8(4) + 48 = 64 - 80 - 32 + 48 = 0

So,x = 4 is an x-intercept

Let's try x = - 2;

(-2)³ - 5(-2)² - 8(-2) + 48 = -8 - 20 + 16 + 48 = 36 ≠ 0.

So, x = -2 is not an x-intercept.

Let's try x = 2;

(2)³ - 5(2)² - 8(2) + 48 = 8 - 20 - 16 + 48 = 20 ≠ 0

So, x = 2 is not an x-intercept

Answer:

y = -2.5x + 2.5

Step-by-step explanation:

Put the equation into y = mx + b form by isolating y:

2x - 5y - 10 = 0

2x - 5y = 10

-5y = -2x + 10

y = 2/5x - 2

Perpendicular lines have opposite reciprocal slopes, so the line's slope will be -5/2, or -2.5

Plug in the slope and given point into y = mx + b, and solve for b:

y = mx + b

5 = -2.5(-1) + b

5 = 2.5 + b

2.5 = b

Plug in the slope and y intercept:

y = mx + b

y = -2.5x + 2.5 is the equation of the perpendicular line

The value of h(-4) for the given function is -13.

The given function is h(t) = 2t - 5.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

Part A:

Put t=-4 in the given function, we get

h(-4) = 2(-4)-5

= -8-5

= -13

Part B:

Substitute h(t)=23 in the given function, we get

23=2t-5

⇒2t=23+5

⇒2t=28

⇒t=14

Part C:

Put t=13 in the given function, we get

h(13)=2(13)-5

= 26-5

= 21

Substitute h(t)=-33 in the given function, we get

-33=2t-5

⇒2t=-33+5

⇒2t=-28

⇒t=-14

Therefore, the value of h(-4) for the given function is -13.

Answer:

d is greater than c, since at [tex]x = 0, g(x) > f(x)[/tex]

Step-by-step explanation:

We are given two exponential functions, f(x) and g(x).

Since f has the higher base(3 instead of 2 in g), it increases faster, so initially, g is greater than f, and after point (p,q), f is greater than g.

The values of c and d are found when [tex]x = 0[/tex]. At this point, we have that  function g is greater than function f, which means that d is greater than c.

Step-by-step explanation:

Multiply the speed of the turtle ( 0.69 miles per hour) by the number of hours it takes ( 1.75 hours)

Answer: 1.2075

Step-by-step explanation:

multiply 0.69*1.75 and u will get 1.2075

The domain is the set of all x-coordinates and

the range is the set of all y-coordinates.

So the domain for this relation is {0, 1, 2, 3, 4}

and the range is {0, -1, -4, -9, -16}.

Now, I graph these points below.

For the relation tobe a function, it must pass the vertical line test.

If we can draw a vertical line that passes through only one point

anywhere on the graph, the relation is a function.

Notice that if you were to draw a vertical line,

no line would intersect two points on the same line.

Step-by-step explanation:

Answer:

B = 31°

a = 18.9

b = 11.3

Step-by-step explanation:

✔️B = 180° - (90° + 59°) (sum of triangle)

B = 31°

✔️Use trigonometric ratio to find a:

Reference angle = 59°

Side opposite to reference angle = a

Hypotenuse = 22

Thus,

Sin 59 = a/22

Multiply both sides by 22

22*sin 59 = a

18.9 = a

a = 18.9 (nearest tenth)

✔️Use trigonometric ratio to find a:

Reference angle = B = 31°

Side opposite to reference angle = b

Hypotenuse = 22

Thus,

Sin 31 = b/22

Multiply both sides by 22

22*sin 31 = b

11.3 = b

b = 11.3 (nearest tenth)
