what is (3x² + 5x - 9) + (7x² + 2x + 10)?
I will give brainiest to the answer with step-by-step explanation :
Answer:
10x^2+7x+1
Step-by-step explanation:
Let's simplify this step-by-step.
3x^2+5x−9+7x^2+2x+10
=3x^2+5x+−9+7^x2+2x+10
After, combine like terms. (Simplify the expression)
Here is a step-by-step row.
= 3x^2+5x+-9+7x^2+2x+10
= (3x^2+7x^2)+(5x+2x)+(-9+10)
= 10x^2+7x+1
That is the most simplified form, I hope this helped!

Parallel lines intersect at exactly one point. ,
Parallel lines intersect infinitely many times.
Parallel lines intersect infinitely many times. ,
Parallel lines have equal slopes.
Parallel lines have equal slopes. ,
Parallel lines have negative reciprocal slopes.
Answer:
Step-by-step explanation:
Parallel lines have identical slopes and different y intercepts.
y = 3x + 2
y = 3x + 9
These lines are parallel with the same slopes (3) and different y intercepts (2 and 9)

Step-by-step explanation:
Answer:
34 1/2
if you use the distributive property and multiply 11×3 you would get 33 then multiply 1/2×3 you get 3/2 or 1 1/2 then add 33+1 1/2 and you get 34 1/2. hope this helped.
Which statement accurately describes the vector shown?
Answer:
magnitude of √61 and a direction angle equal to approximately 40°
Step-by-step explanation:
I inserted the x,y axis into a vector calculator to get the magnitude and angle :D
The magnitude of the vector is √61 and the direction of the angle is 40 degrees option (C) magnitude of √61 and a direction angle equal to approximately 40° is correct.
What is a vector?It is defined as the quantity that has magnitude as well as direction also the vector always follows the sum triangle law.
We have a vector shown in the picture.
The coordinate of the vector are:
The tail coordinate = (0, 0)
The head coordinate = (6, 5)
We can find the magnitude of the vector using the distance formula:
The distance formula can be given as:
[tex]\rm M=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]\rm M=\sqrt{(6-0)^2+(5-0)^2}[/tex]
M = √61
The direction of the angle:
tanA = 5/6
tanA = 0.8333
A =39.80 ≈ 40 degrees
Thus, the magnitude of the vector is √61 and the direction of the angle is 40 degrees option (C) magnitude of √61 and a direction angle equal to approximately 40° is correct.

6. What are the solutions for p2 - 16 = 0 ?
A) {-4,4} B) {4}
C) {-8, 8} D) {8}
Answer:
A
Step-by-step explanation:
Given
p² - 16 = 0 ( add 16 to both sides )
p² = 16 ( take the square root of both sides )
p = ± [tex]\sqrt{16}[/tex] = ± 4
Thus solution is { - 4, 4 } → A
Which expression is equivalent to 8x - 12y + 32?
A. 16(0.5x 4y +32)
B. 16(0.5x - 0.75y + 32)
C. 16(0.5x - 0.75y + 2)
D. 16(0.5x + 4y +2)
Answer:
It's the third
16(0.5x - 0.75y +2)
Step-by-step explanation:
You just divide everything by 16
8x/16= 1/2x=0.5x
-12y/16 = -3/4x=-0.75x
32/16=2

Find the length of arc AB. Use 3.14 for T,
Round to the nearest tenth.
20
1 ? ]cm
Please help
Answer:
12.4 cm
Step-by-step explanation:
Length of an arc AB = [tex] \frac{\theta}{360} \times 2 \pi r [/tex]
Where,
[tex] \theta = 90 [/tex]
[tex] \pi = 90 [/tex]
r = 7.9 cm
Plug in the values
Length of an arc AB = [tex] \frac{90}{360} \times 2 \times 3.14 \times 7.9 [/tex]
[tex] = \frac{90 \times 2 \times 3.14 \times 7.9}{360} [/tex]
Length of an arc AB = 12.4 cm (nearest tenth)
Answer:
Step-by-step explanation:
answer is 12.4cm !

Fiona can make 8 cards in 12 hour. She divides to find the number of cards she can make per hour, but she makes a mistake. Three of these reasons explain why her answer must be wrong. Which does NOT?
Answer:
2/3 card per hour
Step-by-step explanation:
The correct calculation is given below
The number of cards she can make per hour is :
12 hours = 8 cards
1 hour = x cards
Cross Multiply
12 hours × x cards = 8 cards × 1 hour
x cards = 8 cards × 1 hour/12 hours
x cards = 2/3 card
She can make 2/3 card per hour

x -2y = 1
-x -4y = -13
-6y = -12 divide both sides by -6
y=2
x-2y=1
x -2*2 =1
x=1+4=5
Answer:
(5,2)
Step-by-step explanation:
x=1+2y and x+4y=13
1+2y+4y=13
y=2
x=1+2*2
x=5

What additional piece of information would prove DABD ≅ DCBD?
Answer:
∠BAD ≅ ∠BCD
Step-by-step explanation:
The complete equation is attached.
Two triangles are congruent to each other if all their three sides are equal to each other and all their three angles are equal to each other.
The angle side angle (ASA) congruence theorem states that two triangles are congruent if two angles of one triangle is equal to two angles of the other triangle and also if their included side are equal.
Since AB = BC, ∠ABD = ∠CBD. For ∠ABD ≅ ∠CBD based on ASA then ∠BAD ≅ ∠BCD
3(x + 10) + 6 = 3(x + 12)
Answer:
x = infinite amount of solutions
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
3(x + 10) + 6 = 3(x + 12)
Step 2: Solve for x
Distribute 3: 3x + 30 + 6 = 3x + 36Combine like terms: 3x + 36 = 3x + 36Subtract 36 on both sides: 3x = 3xDivide 3 on both sides: x = xHere we see that x does indeed equal x. We can plug in any number x and it would render the equation true.
∴ x = infinite amount of solutions
Answer:
infinitely many solutions / all solutions
Step-by-step explanation:
you distribute 3x+30+6 = 3x+36combine like terms 3x+36 = 3x+36realise the 2 terms are the same so x can be anythingDetermine if the function is even, odd, or neither.

Jessica rented a truck to move into another apartment. The rental charge is $140 per day plus $0.35 per mile. Write an equation to determine x, the number of miles she can drive the truck if the cost is y.
Answer:
y=0.35x+140Step-by-step explanation:
Step one:
given data
The rental charge is $140 per day
additional charges per mile driven = $0.35 per mile
Step two:
Required
The expression for the total charges
let the number of miles be x, and the total charges be y
the expression for the total charges is
y=0.35x+140
Mrs.Stone is three times older than her younger daughter, Joyce, but only two times older than her older daughter, Alex. How old is Mrs.Stone now, if 9 years ago Alex was two times okder than Joyce? Mrs.Stone is three times older than her younger daughter, Joyce, but only two times older than her older daughter, Alex. How old is Mrs.Stone now, if 9 years ago Alex was two times okder than Joyce?
Answer:
54 years
Step-by-step explanation:
Joyce age = x
Alex age = y
3x = 2y - - - (1)
y - 9 = 2(x - 9)
y - 9 = 2x - 18
-9 + 18 = 2x - y
9 = 2x - y
y = 2x - 9 - - (2)
3x = 2y
3x = 2(2x - 9)
3x = 4x - 18
18 = 4x - 3x
18 = x
Hence,
Mrs stone is 3 * 18 = 54 years
