Perform the operation.
(x^2 + 8x + 8) + (-10x2 + 5x)
Answer:
-9x^2+13x+8
Step-by-step explanation:
Combine like terms-
(x^2 + 8x + 8) + (-10x^2 + 5x)
8x+5x = 13x
(x^2 + 8x + 8) + (-10x^2 + 5x)
-10x^2+x^2 = -9x^2
(x^2 + 8x + 8) + (-10x2 + 5x)
and 8 is just left over, so we put that all together and get...
-9x^2+13x+8
Good luck, have a great day!

Kylie invested $290 in an account paying an interest rate of 2.5% compounded continuously. Assuming no deposits or withdrawals are made, how long would it take, to the nearest tenth of a year, for the value of the account to reach $390?
Answer:
t= 11.9
Step-by-step explanation:
Compounded Continuously:
A=Pe^{rt}
A=Pe
rt
A=390\hspace{35px}P=290\hspace{35px}r=0.025
A=390P=290r=0.025

solve the system by substitution y+X=3 2y+x=-5
Answer:
Step-by-step explanation:
We have the system:
y+x=3
2y+x=-5
the question asks us to solve by substitution..
Let's subtract y from both sides of the first equation
y+x=3
-y -y
x=3-y
now, let's substitute 3-y as x into the second equation
2y+3-y=-5
combine like terms
y+3=-5
subtract 3 from both sides
y=-8
so the value of y is -8
now let's use that information to solve for x; we know that x is 3-y, so let's substitute the value of y to find x
x=3-y
x=3--8
x=11
the value of x is 11
as a point, your answer is (11,-8)
Hope this helps! :D

Jenny's great-grandmother is 86 years old. Jenny is 11 years old. What percent of Jenny's great-grandmother's age is Jenny's age
Answer:
12.79%
Step-by-step explanation:
Let :
Great grand mother = 86 years
Jenny = 11 years
Let the percentage = x
x % of great grandmother's age = Jenny's age
x% * 86 = 11
x/ 100 * 86 = 11
86x / 100 = 11
86x = 100 * 11
86x = 1100
x = 1100/86
x = 12.79
x = 12.79%

What is the equation of the line that passes through the point (-4,4) and has a
slope of 3/4 ?
Answer:
y = 3/4x + 7
Step-by-step explanation:
Put it in point-slope form:
y - 4 = 3/4(x - -4)
y - 4 = 3/4(x + 4)
y - 4 =3/4x + 3
y = 3/4x + 7

What shape(s) have congruent diagonals?
** You may have more than one correct
answer!
****
Square
Trapezoid
Rhombus
Rectangle
Kite
Answer:
Step-by-step explanation:
A B
definition of a parallelogram a quadrilateral with both pairs of opposite sides parallel
five properties/theorems for parallelograms opposite sides are parallel, diagonals bisect each other, opposite sides are congruent, opposite angles are congruent, consecutive angles are supplementary
definition of a rectangle a quadrilateral with four right angles
rectangle theorems if a parallelogram is a rectangle, then its diagonals are congruent; if the diagonals of a parallelogram are congruent, then the paralellogram is a rectangle
five properties of a rectangle opposite sides are congruent and parallel; opposite angles are congruent; consecutive angles are supplementary; diagonals are congruent and bisect each other; all four angles are right angles
definition of a rhombus a quadrilateral with four congruent sides
rhombus theroems the diagonals of a rhombus are perpendicular; if the diagonals of a parallelogram are perpendicular, then the paralellogram is a rhombus; each diagonal of a rhombus bisects a pair of opposite angles
properties of a rhombus all parallelogram properties apply; all four sides are congruent; diagonals are perpendicular; the diagonals bisect opposite angles
definition of a square a quadrilateral with four right angles and four congruent sides
properties of a square the properties of a rectangle plus the properties of a rhombus; four right angles; all four sides are congruent
definition of a trapezoid a quadrilateral with exactly one pair of parallel sides
definition of an isosceles trapezoid a trapezoid with the legs congruent
isosceles trapezoid theroems both pairs of base angles are congruent; the diagonals are congruent
trapezoid median theorem the median of a trapezoid is parallel to the bases and its measure is one-half the sum of the measures of the bases, or median=1/2(x+y)
in these quadrilaterals, the diagonals bisect each other paralellogram, rectangle, rhombus, square
in these quadrilaterals, the diagonals are congruent rectangle, square, isosceles trapezoid
in these quadrilaterals, each of the diagonals bisects a pair of opposite angles rhombus, square
in these quadrilaterals, the diagonals are perpendicular rhombus, square
a rhombus is always a... parallelogram
a square is always a... parallelogram, rhombus, and rectangle
a rectangle is always a... parallelogram
a square is never a... trapezoid, because trapezoids only have one pair of parallel sides
a trapezoid is never a... parallelogram, rhombus, rectangle, or square, because trapezoids only have one pair of parallel sides
these quadrilaterals always have all four congruent sides rhombus, square
these quadrilaterals always have all four right angles rectangle, square
these quadrilaterals always have perpendicular diagonals rhombus, square
if you divide a square into four right triangles by drawing its two diagonals, the measure of each of the angles in the triangles that is not a right angle is... 45 degrees
the diagonals of a rhombus... are not always congruent, but they are always perpendicular and they do always bisect each other, and they do always bisect the pairs of opposite angles
the diagonals of a rectangle... are not always perpendicular, but they are always congruent and they always bisect each other
the diagonals of a parallelogram... always bisect each other
Answer:
squares, rectangles, trapeziods (only if isoceles)
Step-by-step explanation:
Squares are rectangles and rectangles always will have diagonals that are congruent. Trapezoids, if isoceles, will have congruent diagonals.

How much annual income would you need to have if, using the 28/36 ratio, your maximum allowable recurring debt is $500? A. $21,430 b. $30,000 c. $62,500 d. $75,000
Answer: $75,000
Step-by-step explanation:
The 28/36 rule is that the maximum that the person is to spend on household expenses is 28% of their monthly income. 36% of their monthly income is the maximum they can spend on debt and their household expenses.
This means that the maximum they are allowed to spend on debt is:
= 36 - 28
= 8%
If their maximum allowable debt is $500, this is 8% of their gross income. This Gross monthly income is therefore:
500 = x * 8%
= 500/ 8%
= $6,250
Their gross annual income is:
= 6,250 * 12
= $75,000
Answer:
$75,000

Answer:
1. No, Lin is incorrect. If you change both numbers to regular notation, you get that Panama has 4,000,000 residents, and Thailand has 70,000,000 residents. 4 million times 20 is 80 million, not 70 million.
2. 10^8. You need to put 10 to the 8th power because 1 × 10^7 is too little, so it is the next power to use that isn't too small
3. Label each increment 10^7, 2 × 10^7, 3 × 10^7... 9 × 10^7, 10^8.
4. Panama's point would be located 2/5 of the way between 0 and 10^7. Peru's point would be located 1/5 of the way between 3 × 10^7 and 4 × 10^7. Thailand's point would be located right on 7 × 10^7.

Answer:
It should be Ratio and Proportions .
Answer:
Step-by-step explanation:
a proportion. Both ratios are the same thing. If you divide 15000 by 30 you get 500
If you divide 210 by 30, you get 7
It is always true that a proportion will have equal equal ratios on either side of the equal sign.

You wre flying a drone at a height of twelve yards. It has traveled a horizontal of twenty eight. What is the angle of depression from the drones current location down to its starting point
Answer:
23.19°
Step-by-step explanation:
Given that,
The height of a drone = 12 yards
It has traveled a horizontal of 28 yards
We need to find the angle of depression from the drones current location down to its starting point. It can be calculated as :
[tex]\tan\theta=\dfrac{P}{B}\\\\\theta=\tan^{-1}(\dfrac{P}{B})\\\\=\tan^{-1}(\dfrac{12}{28})\\\\=23.19^{\circ}[/tex]
So, the angle of depression is equal to 23.19°.

Give the coordinates of the point that would divide AB into a ratio of 2:1. A(4,4) B(2,-5)
Answer:
(10/3, 1)
Step-by-step explanation:
Give the coordinates of the point that would divide AB into a ratio of 2:1. A(4,4) B(2,-5)
The formula for calculating the coordinate of a point divided in the ratio a:b is expressed as;
X = ax1+bx2/a+b
Y = ay1+by2/a+b
Given the coordinates A(4,4) B(2,-5) divided in the ratio 2:1
X = 2(4)+1(2)/2+1
X = 8+2/3
X = 10/3
Similarly;
Y = 2(4)+1(-5)/2+1
Y = 8-5/3
Y = 3/3
Y = 1
Hence the required coordinate is (10/3, 1)
