Answer:
x = -8, x = 5
Step-by-step explanation:
This can be solved using Factorization method:
[tex] 40 = 3x + {x}^{2} \\ \\ \implies \: {x}^{2} + 3x - 40 = 0 \\ \\ \implies \: {x}^{2} + 8x - 5x- 40 = 0 \\ \\ \implies \: x({x} + 8) - 5(x + 8) = 0 \\ \\ \implies \: ({x} + 8) (x - 5) = 0 \\ \\ \implies \: ({x} + 8) = 0 \: \: or \: \: (x - 5) = 0 \\ \\ \implies \: x = - 8 \: \: or \: \: x = 5 \\ \\ x = - 8, \: \: 5[/tex]

Celeste knows that there are 5,280 feet in 1 mile. What proportion can she use
to find the number of feet in 7 miles?
Answer:
[tex]\frac{1mile}{5,280ft} =\frac{7miles}{"x"feet}[/tex]
Step-by-step explanation:
so there are 5,280 feet in 1 mile
We want to find the number of feet in 7 miles
if we were to set up a proportion it would look something like this :
[tex]\frac{1mile}{5,280ft} =\frac{7miles}{"x"feet}[/tex]
This is a gardener's floor plan of their backyard. Enter the amount of grass, in square yards
needed to completely cover the backyard.
Answer:
39 yd^2
Step-by-step explanation:
First, we must divide the shape into quadrilaterals. The best, and easiest, way to do this is to cut along the line in the middle, below the lower 2 yd mark. This will give us a 1 yard by 3 yard rectangle, 4 yard by 8 yard rectangle, and 2 yard by 2 yard square. The next thing to do is to find the area of each location of the backyard using the A = l x w equation. 1 x 3 = 3, 2 x 2 = 4, 4 x 8 = 32. The final step is to add these individual areas, giving us 39 square yards.
Write 10 3 8 as an improper fraction.
Answer (if the number is 10 3/8):
83/8
Step-by-step explanation:
to find out we multiply the whole number (10) by the denominator (x/8) as shown below
10 * 8 = 80
then we just add the product to the numerator (3/y)
3 + 80 = 83
usually we would simplify the new expresion given -wich is 83/8- by finding the least common denominator, however this improper fraction is already in simplest form

What expression is equivalent to 1-2 sin^2x?
I know the answer is 2cos^2x-1, but unsure how to solve it. Do I use the Pythagorean identity to start?
Thanks!
Answer:
1-2*sin^2 (x) = 2cos^2(x) -1
Step-by-step explanation:
1-2sin^2(x)
= 1-2(1-cos^2(x)) =2cos^2(x)-1; Pythagorean identity, sin^2(x)=1-cos^2(x)
=1-2+2cos^2(x)=2cos^2(x)-1; distribute
= -1+2cos^2(x)=2cos^2(x) -1; collect and rearrange terms
= 2cos^2(x)-1 = 2cos^2(x)-1

What is the perimeter of this rectangle?
Answer:
6√17 units
Step-by-step explanation:
A property of rectangles is that their opposite sides are equal in length.
Hence, to find the perimeter :
AB + BC + CD + DA2(AB) + 2(BC)2(AB + BC)Finding AB by applying distance formula :
AB = √(1 + 3)² + (4 - 3)²AB = √4² + 1²AB = √16 + 1AB = √17Finding BC :
BC = √(3 - 1)² + (-4 - 4)²BC = √2² + (-8)²BC = √4 + 64BC = √68BC = 2√17Perimeter :
P = 2(AB + BC)P = 2(√17 + 2√17)P = 2(3√17)P = 6√17 unitssolve this question please
The value of y in y = 5x if the value of x doubles itself is y also doubles itself; option A
How to solve equation?y = 5x
if x = 2
y = 5(2)
y = 10
if the value of x doubles, for instance, if x = 4
y = 5(4)
y = 20
y = 5/x
if x = 0.5
y = 5/0.5
y = 10
if the value of x triples, for instance, if x = 0.125
y = 5/x
= 5/0.125
y = 40
The value of y in y = 5/x if the value of x triples itself is y also triples itself; option B

What is line?A line is a one-dimensional figure, which has length but no width. A line is made of a set of points which is extended in opposite directions infinitely.
Given function: y = 2x + 7.
As the graph of function 1 is not given.
the rate of change of function 2 : y = 2x + 7.
As the the value of m or rate of change of above equation is 2
m=2.

Which one represents y as a function of x.
Answer:
the graph
Step-by-step explanation:
The statement "*Remember ..." tells you how to identify the functional relations.
__
In the top diagram, each x-value maps to more than one y-value. Effectively, that means x is repeating (not a function).
In the set of ordered pairs, the value 3 shows up as an x-value more than once. It repeats (not a function).
In the graph, each value of x is shown as corresponding to exactly one value of y. The graph shows y as a function of x.
On the mapping one
0 has two ranges i.e 0 and 12
As it doesn't has unique range it's not a functionWhere as in the graph
Every x has unique y f(x)=yGraph represents a function
