Answer:
(- 1, 4 )
Step-by-step explanation:
Given the 2 equations
3x + 4y = 13 → (1)
2x - 2y = - 10 → (2)
Multiplying (2) by 2 and adding to (1) eliminates the term in y
4x - 4y = - 20 → (3)
Add (1) and (3) term by term to eliminate y, that is
7x + 0 = - 7
7x = - 7 ( divide both sides by 7 )
x = - 1
Substitute x = - 1 into either of the 2 equations and solve for y
Substituting into (1)
3(- 1) + 4y = 13
- 3 + 4y = 13 ( add 3 to both sides )
4y = 16 ( divide both sides by 4 )
y = 4
solution is (- 1, 4 )
Solve for a: 3a + 11 > 5 Which graph shows the solutions?
Answer: The first one
Step-by-step explanation:
3a + 11 > 5
Subtract 11 from both sides:-
3a > 5 - 11
3a > -6
a > -2
Answer:
It would be the first one
Step-by-step explanation:
problem---> 3a + 11 > 5
FIND a
1. Subtract 11 from both sides:-
which would look like this "3a > 5 - 11"
=3a > -6
a > -2
ANSWER; C.
Find the value of X AND Y: Show your work.
We are given:
AB = 7x + 10
BD = 9x - 2
∠DBC = 9y - 9
∠ABC = 90°
AB = BD
Solving for x:
We are given that AB = BD
7x + 10 = 9x - 2 [since AB = 7x+10 and BD = 9x-2]
10 = 2x - 2 [subtracting 7x from both sides]
2x = 12 [adding 2 on both sides]
x = 6 [dividing both sides by 2]
Hence, x = 6
Solving for y:_______________________________________________
We know that AD is a straight line,
So, ∠ABC and ∠DBC must form a linear pair
∠ABC + ∠DBC = 180°
90 + 9y-9 = 180
9y - 9 = 90 [subtracting 90 from both sides]
9y = 99 [adding 9 on both sides]
y = 11 [dividing both sides by 9]
Hence, y = 11
Simplify the expression:
4+4+7d
Answer:
8+7d
Step-by-step explanation:
So forest you combine like terms
4+4=8
There are no longer any like terms so your finished product is 8+7d
what is 9 : 45 = 6 : ?
Answer:6:45
Step-by-step explanation:
Answer:
x = 30
Step-by-step explanation:
a ratio is just a fraction
9:45 = 9/45
6:x = 6/x
now you have 9/45 = 6/x
cross multiply:
9 * x = 45 * 6
9x = 270
divide both sides by 9
9x/9 = 270/9
x = 30

Carla and Andrew have 29 chocolate chip cookies. Andrew has 8 more than twice Carla’s cookies. How many cookies does each person have?
Step-by-step explanation:
29 cookies
Carla has X cookies
Andrew has 8+ 2X cookies
x + 8 + 2x = 29
3x = 29-8
3x= 21
x = 7 / Carla has 7 cookies
8+ 2x = 8+2•7= 8+14=22 / Andrew has 22 cookies
what is 0.45 divide by 0.3 please show work.
Step-by-step explanation:
We can use standard form to make it simpler to deal with.
0.45=45×10^-2
0.3=3×10^-1
Now 45÷3=15
10^-2÷10^-1=10^-1
So the answer is 15×10^-1 OR 1.5
State the degree and end behavior of the following polynomial f(x)=4x^3+3x^5-x^2 - 2
Answer:
Degree
Five Degree
End Behavior
When x approaches negative infinity, f(x) approaches the negative infinity as well.
When x approaches positive infinity, f(x) approaches positive infinity.
Step-by-step explanation:
[tex]y = 4 {x}^{3} + 3 {x}^{5} - {x}^{2} - 2[/tex]
A five-degree polynomial function. Rearrange the terms.
[tex]y = 3 {x}^{5} + 4 {x}^{3} - {x}^{2} - 2[/tex]
Because it is an odd-degree function, the graph increases from negative infinity and ends by increasing at positive infinity.
Graph / End Behavior
When x approaches negative infinity, f(x) approaches the negative infinity as well.
When x approaches positive infinity, f(x) approaches positive infinity.

Read the excerpt from Heart of a Samurai and then answer the question.
The strangers leaped out of their boats and pulled them up on the small beach. By signs, they made it clear the castaways should climb aboard.
The fishermen exchanged frightened glances and whispered to one another,
“What about Denzo and Jusuke?”
Gesturing, Manjiro communicated to the strangers about the two men in the cave. Denzo and Jusuke were retrieved, both of them so weak they had to be carried to the boats. Everyone found a place and the sailors shoved off. The two boats rowed away from the island toward an unknown future.
The sun flickered on the restless waves just as it always did. The wind blew just as steadily as it always had. Yet everything had changed. They had been rescued from the island, only to be taken captive by barbarians.
Manjiro stared at the strangers when he thought they weren’t looking. Sometimes he caught them staring at him when they thought he wasn’t looking.
What do the details in this excerpt help readers to infer about the barbarians?
A. They are just as mean and monstrous as the fishermen expect them to be.
B. They are suspicious creatures who seem to be from a place other than Earth.
C. They have a plan to humiliate the fishermen and are waiting for the right time.
D. They are just as curious about the fishermen as the fishermen are about them.
Answer:
D
Step-by-step explanation:
"Manjiro stared at the strangers when he thought they weren’t looking. Sometimes he caught them staring at him when they thought he wasn’t looking."
"The fishermen exchanged frightened glances and whispered to one another,"

Answer:
Option D is correct .
Step by step explanation:
A function is given to us and we need to find its inverse . The function is g(x) = -2x⁵ - 2.
So for finding its inverse , exachange x with y .
⇒ g(x) = -2x⁵ - 2 .
Let g(x) = y ,
⇒ y = -2x⁵ - 2 .
Replace x with y ,
⇒ x = -2y⁵ - 2
⇒ x + 2 = -2y⁵
⇒ y⁵ = x+2 / -2
⇒ y⁵ = (-1) ( x + 2) / (-1)(-2)
⇒ y⁵ = -x - 2/ 2
⇒ y = ⁵√ [ ( -x -2)/2 ]
Hence the inverse of the function is ,
[tex]\boxed{\red{\bf f^{-1}(x)=\sqrt[5]{\dfrac{-x-2}{2}}}}[/tex]
Hence the correct option is (D) .

Answer:
One solution
Step-by-step explanation:
maybe
Answer:
There is only one solution to the equation.
x = 0
Step-by-step explanation:
Let rewrite the following equation so that x will be separated from the other numbers. So we do the following......
[tex]\frac{x+4}{4} = \frac{x +3}{3}[/tex]
[tex]12(\frac{x+4}{4}) = 12(\frac{x +3}{3})[/tex]
[tex]3(x +4) = 4(x+3)[/tex]
[tex]3x +12 = 4x +12[/tex]
[tex]12 = 4x - 3x +12[/tex]
[tex]0 = x[/tex]

Lisa needs 250 yards of yarn to knit a hat. She has 185 yards of yarn and needs to buy the rest. How many yards of yarn does she need to buy?
Use the variable y to represent the number of yards of yarn she needs to buy.
Which equation represents this situation and its solution?
250y = 185; y = 55
y + 185 = 250; y = 65
y + 250 = 185; y = 65
185y = 250; y = 55
Answer:
it's answer is y + 185 = 250; y = 65

You go to Macy’s and buy a watch costing $150. The watch is on sale for 60% off. What is the sale price after both discounts?
Answer:
Sale price of the watch = $60
Step-by-step explanation:
Given that:
Cost of the watch at Macy's = $150
Discount on watch = 60%
Amount of discount = 60% of cost
Amount of discount = [tex]\frac{60}{100}*150[/tex]
Amount of discount = 0.60*150 = $90
Price after discount = 150-90
Price after discount = $60
Hence,
Sale price of the watch = $60

what is the value of 4(2f-3d)+2(2d+e)
Answer:
8f - 8d + 2e
Step-by-step explanation:
8f-12d+4d+2e = 8f - 8d + 2e
Answer:
−8d+8f+5.436564
Step-by-step explanation:
Let's simplify step-by-step.
4(2f−3d)+2(2d+2.718282)
Distribute:
=(4)(2f)+(4)(−3d)+(2)(2d)+(2)(2.718282)
=8f+−12d+4d+5.436564
Combine Like Terms:
=8f+−12d+4d+5.436564
=(−12d+4d)+(8f)+(5.436564)
=−8d+8f+5.436564
Answer:
=−8d+8f+5.436564
6 (2n + 5 ) = 66
solve for n
Answer:
n=3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6(2n+5)=66
(6)(2n)+(6)(5)=66(Distribute)
12n+30=66
Step 2: Subtract 30 from both sides.
12n+30−30=66−30
12n=36
Step 3: Divide both sides by 12.
12n/12 = 36/12
n=3
Answer:
n = 3
Step-by-step explanation:
Distribute 6 into 2n+5, which is 12n +30
Subtract 30 from 66, which is 36
Divide 36 by 12
You're left with n = 3
Or in numbers:
6(2n+5)=66
12n+30=66
12n=36
n=3
