Answer: If you are given ordered pairs and asked if they are solutions to the equation, substitute the values in for X and Y. See if the 2 sides equal. If they do equal, then that ordered pair is a solution. If they don't equal, then the ordered pair is not a solution.

Evaluate using the functions f(x) = 3x–8 and g(x) = -x2+ 4x–11.
1 . f(10+10
2. g(-9)+7
3. -2xg(4)
4. f(-4)-g(7)
5. Given f(x)= 9 –2x, if f(x)= 19, find the value of x.
The value of f(10)+10 for the given function is 32.
The given functions are f(x) = 3x-8 and g(x) = -x²+ 4x-11.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
1) Put x=10 in the function f(x) = 3x-8, we get
f(10)=3(10)-8
= 22
So, f(10)+10
= 22+10=32
2) Put x=-9 in the function g(x) = -x²+ 4x-11, we get
g(-9)=-(-9)²+4(-9)-11
= -81-36-11
= -128
So, g(-9)+7
= -128+7
= -121
3) Put x=4 in the function g(x) = -x²+ 4x-11, we get
g(4) = -(4)²+4(4)-11
=-16+16-11
=-11
Now, -2xg(4) =-2x(-11)
=22x
4) Put x=-4 in the function f(x) = 3x-8, we get
(-4)=3(-4)-8
= -20
Put x=7 in the function g(x) = -x²+ 4x-11, we get
g(7)=-(7)²+4(7)-11
= -49+28-11
= -32
5. Given f(x)= 9 –2x, if f(x)= 19
Now, 9-2x=19
⇒ -2x=10
⇒ x=-5
Therefore, the value of f(10)+10 for the given function is 32.

The ratio of blondes to brunettes in Ms. Sarni's class is 2:3. If there are a total of 25 students, how many of the have blonde hair? *
Answer:
the number of blonde hair is 10
Step-by-step explanation:
The computation of the number of blonde hair is shown below;
Given that
Ratio of blonde to brunetees is 2:3
And, there is total of 25 students
So, the number of blonde hair is
= 25 × 2 ÷ (2 + 3)
= 25 × 2 ÷ 5
= 10
Hence, the number of blonde hair is 10

Find the areas of these parallelograms, drawn on a centimetre grid.
b)
a)
Answer:
a-16cm
b-12cm if not iwill look again
Step-by-step explanation:
Area of the parallelograms are :(a) = 16 cm² and (b) = 12 cm² which is drawn on a centimeter grid.
What is Parallelogram?A parallelogram is defined as a special type of quadrilateral that has both pairs of opposite sides parallel and equal. A parallelogram is a square and a rhombus is a square.
The formula to calculate the area of a parallelogram can thus be given as,
Area of parallelogram = b × h square units
where b is the length of the base and h is the height or altitude
For parallelogram (a),
length of the base = 4 cm
the height or altitude = 4 cm
Area of parallelogram (a) = b × h = 4 × 4
Area of parallelogram (a) = 16 cm²
For parallelogram (b),
length of the base = 2 cm
the height or altitude = 6 cm
Area of parallelogram (b) = b × h = 2 × 6
Area of parallelogram (b) = 12 cm²

You are taking a trip at the same time as another
family. Your family traveled 1.900 miles in 2 days,
their family traveled 2.700 miles in 3 days. Who is
traveling fastera
Answer:
My family is traveling faster, since it is traveling at the rate of 950 miles per day, while the other family travels at 900 miles per day.
Step-by-step explanation:
Since I am taking a trip at the same time as another family, and my family traveled 1,900 miles in 2 days, while their family traveled 2,700 miles in 3 days, to determine who is traveling faster the following calculation must be performed:
1,900 / 2 = 950
2,700 / 3 = 900
Thus, my family is traveling faster, since it is traveling at the rate of 950 miles per day, while the other family travels at 900 miles per day.
Shivani played a video game with three levels. It took her 30 minutes to beat the first level and 1 hour and 45 minutes to beat the second level. Shivani played the final level for 30 minutes to finish the game. She beat the final level and stopped playing at 12:15 P.M. What time did Shivani start playing the game?
Answer:
9:30 am
Step-by-step explanation:
Add 30 minutes + 30 minutes to get 60 minutes, which is one hour. Add 1 hour to 1 hour and 45 minutes to get 2 hours and 45 minutes. Subtract 2 hours from 12:15 pm, to get 10:15. That'll leave you with just 45 minutes left. To make it easier than subtract 45 minutes from 10:15, subtract 15 minutes from 10:15, to end up at 10:00 am. 45 minutes - 15 minutes = 30 minutes, so then you subract 30 minutes from 10:00 am, and you end up at 9:30 am, which is your final answerThe diagram shows three angles at a point.

What exactly is a phrase?
One or more terms in an equation can be added, subtracted, multiplied, or divided.
When we simplify an expression, we always merge similar terms in the expression.
If an expression has two sides, we also preserve all similar terms on one side of the expression.
Example:
An expression is 1 + 3x + 4y = 7.
3 + 4 is a formula.
A formula is 2 x 4 + 6 x 7 - 9.
There is an expression: 33 + 77 - 88.
We can determine the angle in a circle given two angles of 168 degrees and 123 degrees.
168°+123°+x°=360°
291°+x°=360°
291°-x°=360 °

x + 2y = 2
2x + 2y = 4
2x + y = 2
x + y = 4
Answer:
x+y=4
Step-by-step explanation:
No solution means that the lines will never intersect. We know that the slope of line A is -1, and it's y intercept is 2. If you look at the last option for the answer choices, it's slope is also -1, but it's y intercept is at 4. These lines have the same slope, also known as parallel, so they will never intersect, thus giving no solution
