Answer:
x=2,y=5
Step-by-step explanation:
y=8x-11 ----(1)
y=-7x+19----(2)
Replace (1) in (2)
8x-11 =-7x+19
8x+7x=19+11
15x =30
x =30÷2
x =2
If x=2,then replace x=2 in (1)
y=8(2)-11
y=16-11
y=5

A recipe calls for 3 cups of flour to make two batches of dinner rolls. One batch mix 15 rolls. Where is making dinner for 12 people and only needs one roll per person. What proportion will help Laura find how much flowers need to make 12 dinner rolls? A 3/30=x/12 B 3/2=x/12 C 3/15=x/12 D 12/15=x/3
Answer: A. [tex]\dfrac{3}{30}=\dfrac{x}{12}[/tex]
Step-by-step explanation:
According to the recipe,
For 2 batches, 3 cups of flour required.
One batch has 15 mix rolls
Then 2 batches will have 2 (15) = 30 rolls
Each person gets one roll, so 3 cups of flour is required for 30 people.
The quanity of flour is proportional to the number of people.
Let x be the quantity of flour required for 12 people.
By proportion,
[tex]\dfrac{\text{Quantity of flour}}{\text{Quanity of person}}=\dfrac{3}{30}=\dfrac{x}{12}[/tex]
Required proportion: [tex]\dfrac{3}{30}=\dfrac{x}{12}[/tex]
The correct option is A. [tex]\dfrac{3}{30}=\dfrac{x}{12}[/tex]

150 times what number divided by 3 would give you 500?
Must be a whole number!
Answer:
10 because if you multiply 500 by 3 you get 1500 and how many times doe 150 go into it...10 times doing it backwards is sometimes easier :)
Step-by-step explanation:
Answer:
150n÷3=500
150n÷3×3=500×3
150n=1,500
150n÷150=1,500÷150

A triangle with sides of 14 15 and 29 does it form a right triangle 
Answer: No.
Step-by-step explanation: This triangle does not form a right triangle because it does not have a 90 degree angle.
Answer:
No
Step-by-step explanation:
Use Pythagorean Theorem: (a^2 + b^2 = c^2)
a^2 + b^2
(14)^2 + (15)^2
196 + 225 = 421
Now for c:
29^2 = 841
841 does not 421 so its not a right triangle

B. vertical and congruent
C. adjacent and congruent
D. vertical and adjacent
Please help
Answer:
D
Step-by-step explanation:
It d because D is for dogs
Two given angles cannot be both vertical and adjacent which is the correct answer would be option (D)
What are supplementary angles?The supplementary angles are defined as when pairing of angles addition to 180° then they are called supplementary angles. There are two types of supplementary angles.
When two angles are congruent, or equal in size, and they are immediately opposite one another, they are said to be vertical.
Vertical angles do not share a common side, but rather a common vertex or point.
A vertex and a common side are shared by adjacent angles.
Since vertical angles can not have a common side when they are immediately opposite one another, two given angles cannot be both vertical and adjacent.
Hence, the correct answer would be option (D)

A Family travels at a constant rate and drove 420 miles in 7 hours.If they drive at the same speed ,How many miles will they drive in the next four hours.?
Answer:
240 miles
Step-by-step explanation:
Step 1
We find the constant rate at which the family travels
Speed(Rate) = Distance/Time
A Family travels at a constant rate and drove 420 miles in 7 hours.
Speed(Rate) = 420 miles/7 hours
= 60 miles per hour
Step 2
If they drive at the same speed ,How many miles will they drive in the next four hours.?
We are to finally calculate the distance for the next 4 hours
Distance = Speed × Time
Speed = 60 miles per hour
Time = 4 hours
Distance = 60 miles per hour × 4 hours
Distance = 240 miles
Therefore, for the next 4 hours the number of miles they would drive is 240 miles
There are 15 girls in your class this year. That is a 15% increase from last year.
a. Write a proportion to solve for the number of girls in the class last year.
b. Solve the proportion in part (a).
Answer:
13 girls
Step-by-step explanation:
100 + 15 = 115%
115% = 15 girls
1% = 0.13
100% = 0.13 x 100 = 13

It took Ciera 24 minutes to drive 18 miles. It took chains of one hour to drive 46 miles. Who is driving at a faster rate?
Answer:
Ciera is driving at a faster rate.
Step-by-step explanation:
You calculate speed, by dividing distance by time.
So 18 divided by 24 is 0.75. That is Ciera's speed.
And then to calculate the other person/thing's speed you have to divide 46 by 60 minutes (equal to one hour). The speed calculates to 0.7666666667
Therefore, Ciera is driving faster.

Answer:
C. the slope of f(x) is less ...
Step-by-step explanation:
"Slope" is a signed number, so comparison using words like "less than" or "greater than" are expected to be used as they are in the context of signed numbers.
The slope of f(x) is the "rise" divided by the "run" of the graph. From left to right, the two points on the graph of f(x) have a "rise" of -2 for a "run" of +1. The slope of f(x) is ...
m = rise/run = -2/1 = -2
The slope of g(x) is the coefficient of the x-term, -7.
__
In the context of signed numbers, the slope of f(x) is -2 and the slope of g(x) is -7. We know -2 is greater than -7, so the slope of f(x) is greater than the slope of g(x).
However ...
In the real world, the slope of a hill is measured in the same way: rise is divided by run. The slope of a hill is always a positive number, because we're not concerned about what compass direction we're going. We're only concerned with how high we need to raise our foot to take the next step up the hill. That is, we're concerned with the "steepness" of the slope, its magnitude.
In that sense, the function g(x) changes 7 units for a change in x of 1 unit, and the function f(x) changes 2 units for the same change in x. Considered in this way, the "steepness" of the g(x) line is greater than that of the f(x) line. We can say the slope of f(x) is less than the slope of g(x).
_____
If the question is asking about the algebraic relation of the slopes of the lines, then the answer is ...
A. The slope of f(x) is greater ... (-2 > -7)
If the question is asking about the steepness of the lines, as we expect is the case, then the answer is ...
C. The slope of f(x) is less ... (2 < 7)
