Draw graphs of the following inequalities.
a.) X>3
Answer:
Step-by-step explanation:
Jamal uses factoring to find the zeros of the equation x2+4x−32=y. He concludes that the graph intersects the x-axis at x=−4 and x=8.
Which statement BEST explains whether Jamal is correct or incorrect?
A
Jamal is correct because x2+4x−32 is equivalent to (x+4)(x−8).
B
Jamal is correct because x2+4x−32 is equivalent to (x−4)(x+8).
C
Jamal is incorrect because x2+4x−32 is equivalent to (x−4)(x+8).
D
Jamal is incorrect because x2+4x−32 is equivalent to (x+4)(x−8).
Answer:
c)
Step-by-step explanation:
x^2+4x-32 = (x-4)(x+8)
hence,
(x-4)(x+8) = 0
x = 4 or x = -8
the graph intersects at 4 not -4
Jamal is incorrect because x2+4x−32 is equivalent to (x−4)(x+8). Option C is correct.
Jamal uses factoring to find the zeros of the equation x²+4x−32=y. He concludes that the graph intersects the x-axis at x=−4 and x=8.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
x²+4x−32=y
Let y = 0
x²+4x−32=0
x² + 8x - 4x - 32 = 0
x (x + 8) - 4 (x + 8) = 0
(x - 4)(x + 8) = 0
Thus, Jamal is incorrect because x2+4x−32 is equivalent to (x−4)(x+8). Option C is correct.

A paper factory needs to ship an order for 4,500 sheets of yellow paper. The factory will put 50 sheets in each box. How many boxes will the paper factory need to us
Answer:
90
Step-by-step explanation:
If they put 50 sheets per box, then it is just simple division.
4,500 divided by 50 is 90.
Answer:
90 boxes
Step-by-step explanation:
They need to ship 4500 sheets of paper.
They put 50 pages in each box.
# of boxes they will need = amount of paper / amount of paper they put in each box
# of boxes they will need = 4500 / 50 = 90

knowledge about triangles.
A. 5.3yds
B.3.7yds
C.1.9yds
D.2.6yds
Answer:
h=2.142
Step-by-step explanation:
Area of triangle(a)=1/2 b* h
Area of scalene traingle(a)=√s(s-a)(s-b)(s-c)
Semi perimeter(s)=(a+b+c)/2=(6+10+14)/2=15 yd
√s(s-a)(s-b)(s-c)=√15(15-6)(15-10)(15-14)=√15*9*5*1=√225=15 yd
Area of triangle(a)=1/2 b* h

Answer:
the answer is b, 8 units right, and 5 units up
Step-by-step explanation:
The image of △JKL after a translation of 8 unit right and 5 units up to △J"K" L directly.
What is translation?The act of moving a figure or shape from one location to another is known as translation. A figure can move up, down, right, left, or anywhere else in the coordinate system during translation. The only thing that changes about the object in translation is its position; its size stays the same.
Given Graph △JKL with vertices J(-3, 4) K (4, 4), and L (6, -2)
and Graph the image of △JKL after a translation of 1 unit left and 10 units up. Label the image △J'K'L',
and Then translate △JKL 9 units right and 5 units down. Label this image △J"K"L.
from graph coordinates of △J"K"L are J"(5, 9), K"(4, 1) and L"(14, 3)
change in J to J" is (5 - (-3), 9- 4) =(8 , 5),
same for K to K" and L to L"
ΔJKL moves 8 units right and 5 units up to △J"K"L"
Hence 8 units right and 5 units up translation would move △JKL to △J"K" L directly.

The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 10 and h = 9 , then
A = [tex]\frac{1}{2}[/tex] × 10 × 9 = 5 × 9 = 45 in² → a
45
The area (A) of a parallelogram is
A = bh ( b is the base and h the perpendicular height )
Here b = 2 and h = 4 , then
A = 2 × 4 = 8 m² → a

I was told that 3x- was -12 but I can’t understand how they got -12:/
Answer:
6
Step-by-step explanation:
They got 3x-12 because they took
3(x - 4)
and they distrubuted the 3 to the numbers in parenthesis,
how they did this was they multiplied 3 by x and got 3x then they kept the subtraction sign that is in the parenthesis. Then they multiplied 3 by the 4 and got 12.
then the equation was 3x - 12/2 = 6
Answer:
x=8
Step-by-step explanation:
[tex] \frac{3(x - 4)}{2} = 6[/tex]
Multiply 3 by what's in the bracket
[tex] \frac{3x - 12}{2} = 6[/tex]
Multiply through by the LCM of all the denominators
[tex] \frac{2(3x - 12)}{2} = 2 \times 6[/tex]
=The numerator 2 will cancel the denominator 2
[tex]3x - 12 = 12[/tex]
Grouping like terms
[tex]3x = 12 + 12[/tex]
Dividing both sides by 3
[tex] \frac{3x}{3 } = \frac{24}{3} [/tex]
[tex]x = 8[/tex]

Find X round to the nearest tenth.
Answer:
x= 31.8
Step-by-step explanation:
22/sin(75) = 12/sin(x)
or, 22/(12×sin(75)) = 1/sin(x)
or, sin(x) = 12×sin(75)/22
or, x = arcsin(12×sin(75)/22)
or, x = 31.8 (rounded to the nearest tenth)
