Pls help me 35 points in total

Answer:

Quadrants I and II

Step-by-step explanation:

y = x²

y = 3x + 10

x² = 3x + 10                     Substitute x² for y

x² - 3x - 10 = 0                 set the equation = 0

(x - 5) (x + 2)                     Factoring

x - 5 = 0 ; x + 2 = 0

x = 5 or x = -2

Now solving the y

y = x²     or     y = x²

y = (5)²   or y = (-2)²  

y = 25   or  y = 4

The points of interception is points (5, 25) or (-2, 4)  

(5, 25)  in Quadrant I ; (-2, 4) in Quadrant II

Answer:

2nd option

Step-by-step explanation:

given a quadratic in standard form

y = ax² + bx + c

• If a > 0 then minimum vertex

• If a < 0 then maximum vertex

Here a = - 1 < 0 then maximum

The maximum value is the value of the y- coordinate of the vertex

The x- coordinate of the vertex is

x = - [tex]\frac{b}{2a}[/tex]

Here a = - 1 and b = 3 , then

x = - [tex]\frac{3}{-2}[/tex] = [tex]\frac{3}{2}[/tex]

Substitute this value into the equation for corresponding y- value

y = - ([tex]\frac{3}{2}[/tex] )² + 3([tex]\frac{3}{2}[/tex] ) - 1 = - [tex]\frac{9}{4}[/tex] + [tex]\frac{9}{2}[/tex] - 1 = - [tex]\frac{9}{4}[/tex] + [tex]\frac{18}{4}[/tex] - [tex]\frac{4}{4}[/tex] = [tex]\frac{5}{4}[/tex]

Then maximum value of [tex]\frac{5}{4}[/tex]

Answer:

A

Step-by-step explanation:

the x intercept is -1

Answer:

72m

Step-by-step explanation:

since 5cm is 6m, just take 5 and make it 6, so 10cm is 12m and 5cm is 6m

multiply, and you get the answer

Answer:

shortest to longest -

B-77

A-59

C-44

Step-by-step explanation:

To put the sides in order of longest to shortest, first find the largest angle -- the longest side is opposite this angle. Then, find the second largest angle and the side opposite from it to find the next largest angle, and finally, the shortest side will be opposite the smallest angle.

Step-by-step explanation:

Answer: 6x^2+1

(very sorry if this is wrong lol)

Step-by-step explanation:

Substitute all the given numbers into the equation, by doing so this should give you 2x-1+3x+2+x^2.

Since we have a group of x’s add them together, which would make 6x^2, this leaves our -1 and +2 add these these two numbers together to make plus one and finally you will have 6x^2+1

Let x = 0.757575... . Then

100x = 75.757575...

and so

100x - x = 75.757575... - 0.757575...

99x = 75

x = 75/99 = 25/33

Answer:

(8 × 3) + (8×2)

Step-by-step explanation:

Answer:

C = 4s + 6a

C = 4(3) + 6(2)

C = 12 + 12

C = 24

may this answer helps you dear

Step-by-step explanation:

2b - 3/3 - 5 = 10

2b - 1 - 5 = 10

2b - 6 =10

2b -6 +6 = 10 +6

2b = 16

b = 8

Answer:

Sara's mother age : 40 years

Sara's age : 10 years

Step-by-step explanation:

Let Sara's mother age be x

and Sara age be y

Given , Sara's mother is now four time as old as Sara

• x = 4y ...1

also, in five years , she will be three times as old as Sara

In five years , Sara's mother age :- ( x + 5 )

Sara age :- ( y + 5 )

according to the question,

x + 5 = 3 ( y + 5 )

x + 5 = 3y + 15

x - 3y = 10 ... 2

putting value of x from 1 into 2

4y - 3y = 10

y = 10

putting y value in 1

x = 4y = 4 ( 10 ) = 40

So, Sara's mother age is 40years

and Sara's age is 10years .

Answer:

b=-1

Step-by-step explanation:

given.3b+(-5)=(2b)³(-3)2+6=?

3b-5=8b-6+6

3b-5=8b

-5=8b-3b

-5=5b

-5/5=5b/5

b=-1

-3-5=-8-6+6=?

-8=-8=-8

Step-by-step explanation:

-3m-2m<_ 11-76

-5m<_-65

m>_13

therefore, option 1, 13.
