Answer:

The formula for percent change is $\frac{new-old}{old}(100)$ . Because she scored 13 points and scored 22 points in the next game, the new value is 22 and the old value is 13. Plug in the values to get $\frac{22-13}{13}$ or $\frac{9}{13}(100)$ . Multiply the values to get 69.23 or 69.23%.

The sum of the first 5 terms of an AP is 30 and the sum of the four term from T6 to T9 (inclusive) is 69. Find the AP

Ainat [17]

Answer: The AP = 1, ⁷/₂, 6, ¹⁷/₂, 11 ..............

Step-by-step explanation:

From the first statement,

S₅ = ⁵/₂(2a + ( n - 1 )d } = 30

5(2a + 4d )d = 60

10a + 20d = 60

reduce to lowest term to easy calculation by dividing through by 10

a + 2d = 6 -----------------------------------1

second statement

sum of the next 4 terms inclusive

T₉ = ⁹/₂(2a + 8d ) = 69

9(2a + 8d ) = 30 + 69

18a + 72d = 99 x 2

18a + 72d = 198

divide through by 18 to reduce to lowest time

a + 4d = 11 ------------------------------------------2

Now solve the two equation simultaneously to find a and d

a + 2d = 6

a + 4d = 11

-2d = -5

d = ⁵/₂.

Now substitute for d to get a

a + 2(⁵/₂) = 6

a + 5 = 6

a = 6 - 5

a = 1.

Therefore the AP = 1 , ⁷/₂ , 6 , ¹⁷/₂ , 11 , ..............

Find the x-intercept of the line 3x - 9y = 15.

erastovalidia [21]

Answer:

The x-intercept is 5.

Some people prefer you right it as a point (5,0).

Step-by-step explanation:

The x-intercept can be found by setting y=0 and solving for x.

Just like to find the y-intercept you can set x=0 and solve for y.

Let's find the x-intercept.

So we will set y=0 and solve for x:

3x-9y=15

3x-9(0)=15

3x-0 =15

3x =15

Divide both sides by 3:

x =15/3

x =5

So the x-intercept is (5,0).

Help please it’s due hella soon also please leave a small explanation

murzikaleks [220]

1) y=3x-4
When x increases by 1, y increases by 3 so the slope is rise/run → 3
y-int is -4 bc y-value is -4 when x=0

2)y=-3x+4
When x increase by 2, y decreases by 6 so the slope is rise/run → -3
y-int is 4 bc y-value is 4 when x=0

3)y=-1/3x+4
When x increase by 3, y decreases by 1 so the slope is rise/run → -1/3
y-int is 4 bc you now have the equation y=-1/3x+b and u just have to plug in random point from the graph, so ex, 6 into x and 2 into y. You can get 4 as b in the equation.

4)y=1/3x-4
When x increases by 6, y decreases by 2 so the slope is rise/run → 1/3
y-int is -4 bc u do the same thing as 3)
For ex, plug in 6 for x and -2 for y and you can get -4 as the b in the equation.

16x^4-24x^3+20/-4x<br> need help on this problem

Mama L [17]

Assuming ya mean
$\frac{16x^4-24x^3+20}{-4x}$
remember
$\frac{a+b}{c}=\frac{a}{c}+\frac{b}{c}$
and
$\frac{x^m}{x^n}=x^{m-n}$

so
$\frac{16x^4-24x^3+20}{-4x}=$
$\frac{16x^4}{-4x}+\frac{-24x^3}{-4x}+\frac{20}{-4x}=$
$-4x^3+6x^2+\frac{-5}{x}=$
$-4x^3+6x^2-\frac{5}{x}$
that's the best I can do
