Answer:

Step-by-step explanation:
1. (x² - 4x - 10) + (x² - 9x + 3)
= x² - 4x - 10 + x² - 9x + 3
= x² + x² - 4x - 9x + 3 - 10
= 2x² - 13x - 74. (3x² - x + 1) + (15 - 9x - 2x²)
= 3x² - x + 1 + 15 - 9x - 2x²
= 3x² - 2x² - x - 9x + 1 + 15
= x² - 10x + 167. (6 - 2x + 7x²) - (10x - 3 + 3x²)
= 6 - 2x + 7x² - 10x + 3 - 3x²
= 7x² - 3x² - 2x - 10x + 6 + 3
= 4x² - 12x + 9Related Questions

Step-by-step explanation:
because A<C are the only angle ur missing.
Answer:
DC ≅ AB
Step-by-step explanation:
Because AC ≅ AC is given, I'm gonna assume its DC ≅ AB
I know kind of weird that I'm gonna have to assume when I've given 148 answers and I'm of the rank expert, however I looked at that triangle and all of those answers are correctly proving congruence, so it makes no sense to mark you wrong because technically ALL of the sides are given
HELPPP

Answers
Answer:
HL (Hypotenuse Leg)
Step-by-step explanation:
You have BC=CD (Because of reflexive property), AC=DC, and measure of BAC is equal to the measure of BDC, which is 90 degrees. Since these triangles are right and they have a hypotenuse and a leg congruent, you can say that they are congruent because of HL.

Answer:
[tex]a_{n}[/tex] = 22 - 7n
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
8 - 15 = 1 - 8 = - 7
This indicates the sequence is arithmetic with explicit formula
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 15 and d = - 7 , then
[tex]a_{n}[/tex] = 15 - 7(n - 1) = 15 - 7n + 7 = 22 - 7n ← explicit formula

Answer:
19) D (-8, -2)
20) B (0, 8)
Step-by-step explanation:
-x - y = 10
-6x + 11y = 26
-x - y = 10
-x = 10 + y
x = -10 - y
-6x + 11y = 26
-6(-10 - y) + 11y = 26
60 + 6y + 11y = 26
60 + 17y = 26
17y = -34
y = -2
-x - y = 10
-x - (-2) = 10
-x + 2 = 10
-x = 8
x = -8
_______________
-x + y = 8
3x + 2y = 16
-x + y = 8
y = 8 + x
3x + 2y = 16
3x + 2(8 + x) = 16
3x + 16 + 2x = 16
5x + 16 = 16
5x = 0
x = 0
-x + y = 8
-0 + y = 8
y = 8
Bradley estimated the height of a tree at 2.5 meters. Carla estimated that tree's height at 8 feet.
How could a conversion ratio be used to compare Bradley's and Carla's estimates of the tree's height when measured in feet? (1 foot = 0.305 meters)
Answers
Answer: 4.1 feet : 4 feet
Step-by-step explanation:
From the question, we are informed that Bradley estimated the height of a tree at 2.5 meters. Carla estimated that tree's height at 8 feet.
The conversion ratio be used to compare Bradley's and Carla's estimates of the tree's height when measured in feet goes thus:
Since 1 feet = 0.305 meters
2.5 meters will be = 2.5/0.305 = 8.2 feet
Therefore the conversion ratio will be:.
= 8.2 : 8
Reducing to lowest term will be
= 4.1 feet : 4 feet.
= 4.1 : 4

What is the value of y in the equation 9 + y = 8? this is extremely time sensitive
Answers
You have to switch the 8 to the left and the y to the right which would change the equation to 9-8=y
y=1
Answer: y =-1
Step-by-step explanation:y =-1
Last option is correct.
Step-by-step explanation:
The given equation is
In order to solve for y, we need to isolate y.
In this equation 9 is added with y and hence in order to eliminate 9 from the left hand side, we do reverse operation of addition.
The reverse operation of addition is subtraction. Hence, we subtract 9 to both sides of the equation

If n/8 has a remainder of 5, then which of the following has a remainder of 7?
A) n+1/8
B) n+2/8
C) n+5/8
D) n+7/8
Answers
Answer:
[tex]\frac{n+2}{8}[/tex] has a remainder of 7 ⇒ B
Step-by-step explanation:
In m ÷ n = c + [tex]\frac{r}{n}[/tex] ,
m is the dividendn is the divisorc is the quotientr is the remainderm = (n × c) + rLet us use the facts above to solve the question
∵ [tex]\frac{n}{8}[/tex] has a remainder of 5
→ Let us find the first number divided by 8 and give a reminder of 5
that means let the quotient = 1
∵ n = (8 × 1) + 5 = 8 + 5
∴ n = 13
∵ [tex]\frac{n+x}{8}[/tex] has a remainder of 7
→ Let us find the first number divided by 8 and give a reminder of 7
that means let the quotient = 1
∵ n + x = (8 × 1) + 7 = 8 + 7
∴ n + x = 15
∵ n = 13
∴ 13 + x = 15
→ Subtract 13 from both sides
∴ 13 -13 + x = 15 - 13
∴ x = 2
∴ [tex]\frac{n+2}{8}[/tex] has a remainder of 7
