In which quadrant(s) do the graphs of y=x^2 and y=3x+10 intersect?
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

Sara’s mother is now four times as old as Sara. In five years, she will be three times as old as Sara. What are their ages now?
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 .
The bookstore sold m books on Monday and t books on Tuesday. But on Wednesday, r books were
returned. Write the expression for the total books sold.
Answer:
m+t-r
Step-by-step explanation:
∠A and \angle B∠B are supplementary angles. If m\angle A=(7x-15)^{\circ}∠A=(7x−15)
∘
and m\angle B=(2x-3)^{\circ}∠B=(2x−3)
∘
, then find the measure of \angle A∠A.
Answer:
m ∠ A = 139° ; m ∠ B = 41°
Step-by-step explanation:
Supplementary angles sum = 180°
m ∠A + m ∠ B = 180°
(7x - 15) + (2x - 3) = 180°
9x - 18 = 180°
9x = 180 + 18
9x = 198°
x = 22
m ∠A = 7x - 15 = (7·22) - 15 = 154 - 15 = 139°
m ∠ B = 2x - 3 = (2·22) - 3 = 44 - 3 = 41°
Check: m ∠ A + m ∠ B = 180°
139° + 41° = 180

A scale drawing for a plot of land is shown below.
In the drawing, 5 cm represents 6 m.
Assuming the backyard is rectangular, find the area of the real backyard.
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
What is the rule that would be used to go from the pre-image to the image?
a
\large \left(x,y\right)\rightarrow\left(x+6,y\right)
b
\large \left(x,y\right)\rightarrow\left(x-6,y\right)
c
\large \left(x,y\right)\rightarrow\left(x,y+6\right)
d
\large \left(x,y\right)\rightarrow\left(x,y-6\right)

f(x) = -2x^2- 1; Find f(-4)
Answer:
-33
Step-by-step explanation:
write the repeating decimal as a fraction 0.75
the 75 is repeating
Let x = 0.757575... . Then
100x = 75.757575...
and so
100x - x = 75.757575... - 0.757575...
99x = 75
x = 75/99 = 25/33

2b - 3 / 3 (fraction) - 5 = 10.
Solve for B
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

(8x3+3x-2)+(9x2-7+3x-2x3)
Answer:
10x^3+9x^2-9
Step-by-step explanation:
8x^3+2x-2+9x^2-7+2x-2x^3 - Combine like terms
10x^3+9x^2-9
Answer:
[tex]\boxed{\boxed{\sf 6x^3+9x^2+6x-9}}[/tex]
Step-by-step explanation:
[tex]\sf \left(8x^3+3x-2\right)+\left(9x^2-7+3x-2x^3\right)[/tex]
[tex]\sf 8x^3+3x-2+9x^2-7+3x-2x^3[/tex]
Note: If there is a negative sign in front of parentheses, each term within the expression changes sign.
[tex]\Longrightarrow \sf 8x^3+3x-2+9x^2-7+3x-2x^3[/tex]
Now, we need to organize expression into groups like terms:
[tex]\Longrightarrow \sf (8x^3, -2x^3)\: (3x, 3x)\:(-2,-7)[/tex]
[tex]\longmapsto\sf 8x^3-2x^3=6x^3[/tex]
[tex]\longmapsto\sf 3x+3x=6x[/tex]
[tex]\longmapsto\sf -2-7=-9[/tex]
[tex]\boxed{\sf 6x^3+9x^2+6x-9}[/tex]
_____________________________
[tex]\sf 2(4+9m)[/tex]
Rearrange terms

18m+8
Solution
Solution18m+8
[tex]2(4+9m)[/tex]
[tex]2(9m+4)[/tex]

(Therefore, 18m+8 is the final answer)
