The effect that 'h' have on the graph of a parabola is Horizontal shift or translation .

<h3>What is translation?</h3>

A translation is the movement of a shape up, down , this can also be movement from side to side.

Even though there is movement, its appearance remains the same in any other way, hence, h values cause left or right movement with respect to the graph.

What is an equation of the line that passes through the point (8,-8)(8,−8) and is perpendicular to the line 4x-3y=184x−3y=18?

Kitty [74]

Answer:

The equation of the line is $y = -\frac{3x}{4} - 2$

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

$y = mx + b$

In which m is the slope and b is the y-intercept.

Perpendicular lines:

When two lines are perpendicular, the multiplication of their slopes is -1.

Perpendicular to the line 4x-3y=18

First, we place this line into the format, to find the slope:

$4x - 3y = 18$

$3y = 4x - 18$

$y = \frac{4x}{3} - 6$

This line has slope 4/3. So, for the perpendicular line, the slope will be of m as such:

$\frac{4m}{3} = -1$

$4m = -3$

$m = -\frac{3}{4}$

So the desired line will have an equation in the following format:

$y = -\frac{3x}{4} + b$

Passes through the point (8,-8)

We use this to find b. This point means that when $x = 8, y = -8$ . So

$y = -\frac{3x}{4} + b$

$-8 = -\frac{3*8}{4} + b$

$-8 = -6 + b$

$b = -2$

$y = -\frac{3x}{4} - 2$

Twenty-one is 25% of what number?<br><br> A. 5.25<br> B. 84<br> C. 10.5<br> D. 63

musickatia [10]

Answer: 84

Step-by-step explanation:

When substituting this question into an algebraic equation you can write it as:

21=.25x

(x clearly represents the number you are trying to find)

When you divide both sides by .25 to isolate x you get x=84

7. Tyson obtained a loan from the bank at 7.5% simple interest for 2. 5 years. If the simple interest was

9966 [12]

Answer:

7.He borrowed $1853.33

8.She received $28990.936

Step-by-step explanation:

7.Let x be the amount borrowed by Tyson

Rate of interest = 7.5%

Time = 2.5 years

Simple Interest = 347.50

Formula : $Si = \frac{P \times T \times R}{100}$

Where SI = simple interest

P = Principal

T = Time

R = Rate of interest

Substitute the values in the formula :

$347.50=\frac{x \times 2.5 \times 7.5}{100}\\\frac{347.50 \times 100}{2.5 \times 7.5}=x\\1853.33=x$

Hence he borrowed $1853.33

8) Principal = 20000

Rate of interest = 9.5%

No. of compounds per year = 2

Time = 4 years

Formula : $A=P(1+\frac{r}{n})z^{nt}$

Where A= amount

r = Rate of interest

n = no. of compounds

t = time

Substitute the values in the formula :

So, $A=20000(1+\frac{9.5}{200})^{2(4)}$

A=28990.936

Hence she received $28990.936

15 of 20 answer

expeople1 [14]

Answer:

8 bags

Step-by-step explanation:

You divided them by 20 which gives you 4. So you take the 3 and multiply by 4 which is 12 bags. And then you do the same for your bags which makes you do 2 times 4 which gives you 8. You take 20 - 12 and that leaves you with 8.
