How many points of intersection are on the graph of the following system?lbrace y = x2 + 3x − 7
y − x = 9

The linear-quadratic system has
(select)
points of intersection.

Answers

Answer 1

Answer:

Answer:

2 points of interception of (3.12 , 12./12) and (-5.12 , 3.87)

Step-by-step explanation:

y − x = 9

y = x + 9

x+9 = x²+3x-7

x²+2x-16=0

x = (-2±√2²-4(1)(-16)) / 2 = (-2 ± √68) / 2 = -1 ± √17

x = 3.12 or x = -5.12

y = 12.12 or y = -3.87

myra's stamp collection consisted of 120 stamps in october. By the following march, her collection had grown to 138 stamps. By how much did her collection increase between october and march

Answers

Answer:

18 stamp increase

15 % increase

Step-by-step explanation:

To find the increase in number , we take the number of stamps in march and subtract the stamps in october

128-120 = 18

To find the percent increase, we take the number of stamps that we gained over the original amount of stamps * 100%

percent increase = 18/120 * 100%

.15 * 100%

15% increase

Which angle measure less than or equal to 360° is equivalent to an angle of 17pi/4

Answers

Answer:

Therefore, The required measure of the angle is 45°

Step-by-step explanation:

$\text{The angle is given to be : }(17\pi)/(4)$

Now, the value of angle π is equivalent to 180°

So, finding the value of the given angle in degrees

$\implies\text{The degree measure of the given angle = }(17)/(4)* 180=765$

Now, the angle is 765°

We need to find the angle which measures less than or equal to 360° and is equivalent to 765°

765 = 360 × 2 + 45°

So, 360° angle is 45° less than the given angle.

Therefore, The required measure of the angle is 45°

The correct answer is

45 degrees

A sequence is defined by the recursive formula f(n + 1) = 1.5f(n). Which sequence could be generated using the formula? –12, –18, –27, ... –20, 30, –45, ... –18, –16.5, –15, ... –16, –17.5, –19, ...

Answers

Formula f(n+1) = 1.5 f(n) => f(n+1) / f(n) = 1.5. That means, that you have to search for a sequence where the ratio of two consecutive terms is 1.5. The first sequence is the only one that meets that: - 18 / - 12 = 1.5 and - 27 / - 18 = 1.5. So, the answer is the first option: -12, -18, -27, ...

Answer: –12, –18, –27, ... [ A.K.A: (A.) ]

Express 64% as a fraction in simplest form.

Answers

The given percentage in simplest form of fraction as 16/25.

What is the fraction?

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

The given percentage is 64%.

To change a percent to a fraction, put the percentage over 100 (after removing the % sign) and simplify if necessary

Now, 64/100

= 16/25

Therefore, the given percentage in simplest form of fraction as 16/25.

64% = 64 / 100

2 into 64 is 32, and 2 into 100 is 50

64 / 100 = 32 / 50

2 again into 32 is 16 and 2 into 50 is 25

= 16 / 25

64% = 16 / 25
