Answer:
-14x² +19x
Step-by-step explanation:
You want the sum of the expressions (-8x² +9x) and (-6x² +10x).
SimplificationThe sum is found by adding like terms: terms with the variable to the same power.
(-8x² +9x) + (-6x² +10x)
= (-8 -6)x² +(9 +10)x
= -14x² +19x

Write a real world problem that you can model with the two step equation 5x+7=10.
The equation can be expressed as the product of 5 and a number increased by 7 is equal to 10.
Solving linear equationLinear equation are equations that has a leading degree of 1. The standard linear equation is given as y = mx + b
Given the expression 5x + 7 = 10
Subtract 7 from both sides to have:
5x+ 7 - 7 = 10 -7
5x = 10 - 7
5x = 3
5x - 3 = 0
5x = 3
x = 3/5
The equation can be expressed as the product of 5 and a number increased by 7 is equal to 10.

In the figure, the angle x° is an alternate angle with angle 54° so the measure of angle x° is 54°.
We have,
From the figure,
Line m and line n are parallel.
Line t is the transversal line.
Now,
Alternate angles are a pair of angles that are formed when a transversal (a line that crosses two other lines) intersects two parallel lines.
When this happens, the alternate angles are on opposite sides of the transversal and are congruent, which means they have the same measure.
Angle 54° and angle x° are alternate angles.
Alternate angles are equal.
So,
x° = 54°
Thus,
The measure of angle x° in the figure is 54°.

The graph below shows the solution to a system of inequalities: Solid line joining ordered pairs 0, 3.75 and 15, 0. Shade the portion of the graph above the line in the first and second quadrant Which of the following inequalities is modeled by the graph? (5 points) Group of answer choices x + 4y ≥ 15; y ≥ 0 x − 4y ≥ 15; y ≥ 0 x + 4y ≤ 15; y ≥ 0 −x − 4y ≥ 15; y ≥ 0
Answer:
x + 4y ≥ 15; y ≥ 0
Step-by-step explanation:
The solid line signifies it is a ≤ or ≥.
The equation of the line joining 0, 3.75 and 15, 0 is gotten using the formula:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\Substituting:\\\\y-3.75=\frac{0-3.75}{15-0}(x-0)\\\\ y-3.75=-\frac{1}{4}x\\\\y=-\frac{1}{4}x+3.75\\\\4y=-x+15\\\\4y+x=15[/tex]
Since the first and second quadrant are shaded, this represents y ≥ 0.
Also, above the solid line of 4y + x = 15 is shaded, this represents 4y + x ≥ 15.
Hence the inequality modeled is x + 4y ≥ 15; y ≥ 0

Lynne needs to borrow $9500 for cosmetic surgery she obtains a loan from her grandmother for 24 months at a simple interest rate of 9.3% what is the loans future value?
Answer:
$11267
Step-by-step explanation:
Loan Future value = amount borrowed + interest
Amount borrowed = 9500
Interest = Principal * Rate * Time/100
Interest = 9500*9.3 * 2/100
Interest = 95*9.3 * 2
Interest = $1767
Loan Future amount = 9500 + 1767
Loan Future amount = $11267

What number is represented by point A?
Answer:
Third choice, 3/4
Step-by-step explanation:
There's 3 lines in the middle before it's the number 1, if u count 1 into the lines then there's 4, 1 divided by 4 is 0.25 or 1/4, so each small line is going up or down by 1/4. So it's 0 -> 1/4 -> 2/4 -> 3/4 which is A -> 4/4 which is 1
So A is 3/4
Justify why the sum of 3a and
2b cannot be represented as 5ab.
Answer:
You cannot add two numbers that have different variables.
Step-by-step explanation:
You can multiply them, but since 3 is multiplied by "a" or a different number than "b" then the answer would be incorrect.
Answer:
because 3a and 3b have different variables. You can't add "unlike terms" to each other because the variables have different values. by writing 3a+2b as 5ab, you're completely changing the meaning of the problem. You would get a totally different answer than you would by just adding the two terms together.

The length of the kite string is 16. 984m
A kite is currently flying at an altitude of 9 meters above the ground.
and, the angle of elevation from the ground to the kite is 32 degrees.
To find the length of the kite string to the nearest meter.
Now, According to the question:
Let the length of the kite string be x m.
From the diagram, the length of the kite string x m is hypothesis
The altitude is 9 m is opposite
and, horizontal line is adjacent.
Formula is:
Sin θ = opposite / hypotenuse
where Sinθ = 32 degree
opposite = 9 m
Hypotenuse = x m
Hence, Sin 32 = 9/x
x = 9/ sin 32 , and Sin 32 degree = 0.5299(approx.)
x = 9/ 0.5299
x = 16. 984 (approx.)
Hence, The length of the kite string is 16. 984m

Cost price of an item is Rs 600. If the selling price is Rs 780, then the profit percent is
Answer:
Profit percentage=30%
Step-by-step explanation:
The profit percentage=profit/cost price×100%
but we can calculate profit as=selling price-cost price
profit=Rs780-Rs600=Rs180
Now substitute the profit value into the formula
Profit percentage=Rs180/Rs600×100%=30%
C.P of an item= Rs.600
S.P of an item = Rs. 780
Profit = SP- CP
= Rs. 780- Rs.600
=Rs.180
Now, profit percent= profit÷ CP × 100%
= 180 ÷ 600 × 100%
