y = 10x + 3
y = 5x + 2
Is it one solution, no solutions, or infinitely many solutions?
Answer:
one solution: (x, y) = (-0.2, 1)
Step-by-step explanation:
The y-coefficients are the same and the x-coefficients are different. That means the lines have different slopes, so they must intersect. The solution is at the one point of intersection.
4. A local Internet provider offers a plan
in which you pay a flat fee of $5.95 per
month plus $0.20 per hour of use.
For how many hours of use were you
billed if your monthly bill is $8.95?
Answer:
15 hours
Step-by-step explanation:
If you use the slope intercept form (y = mx + b), the equation for the internet provider would be:
f = 0.20h + 5.95
where f = the fee, and h being the hours.
8.95 - 5.95 = 3
3 / 0.2 = 15 (hours)
You would need to have 15 hours of use if your monthly bill was $8.95.

Given h(x)=5x-5h(x)=5x−5, find h(2)h(2). it is not 3
Answer:
h(2) = 5
Explanation:
Given h(x)=5x-5
to find h(2) ......replace x with 2
h(2)=5(2)-5
h(2) = 10 - 5
h(2) = 5

Step-by-step explanation:
As we can see it a right angled triangle
so <y =90°
Now
3x + 11° + 25° + 90° = 180°{being sum of angles of triangle}
3x + 126° = 180°
3x = 54°
X = 18°
Use the image from problem 11 to answer this problem.
If angle 1 measures 146°, what is the sum of angles 2 and 4?
Answer:
34.
Step-by-step explanation:
All angles of a triangle combined equal 180, so if 1 angle measures 146, subtract 146 from 180. 180-146=34

This recipe makes a cake big enough to serve 12 people.
Gareth has 22 eggs and plenty of the other ingredients.
He makes the largest cake he can following this recipe.
How many people does his cake serve?
Recipe: Serves 12
140 g butter
240 g sugar
4 eggs
280 g flour
60 ml milk
Answer:
66
Step-by-step explanation:
The recipe states that a 4 egg cake mixture will serve 12 people.
To find the number of people a 1 egg cake mixture will serve: 12 ÷ 4 = 3 ⇒ 1 egg will make a cake big enough to serve 3 people.
If Gareth has 22 eggs, then 22 x 3 = 66
So a 22 egg mixture will be able to serve 66 people.
Answer:
About 60 people
Step-by-step explanation:
1.) Garret has 22 eggs and the recipe calls for four eggs to serve 12.
2.) Garret Can make this cake 5 times with 22 eggs (4 x 5=20)
3. Thus his cake can serve about 60 people
12 (people fed per cake) x 5 (cakes he could make) = 60 people

The product of the ages of three children is 1872. The age of the middle child is the average of the ages of the other two children. What is the sum of their ages
When the product of the ages of three children is 1872, the age of the middle child is the average of the ages of the other two children, then the sum of their ages is 57.
Let, the ages of the three children as A, B, and C.
Given that the product of their ages is 1872, we have:
A * B * C = 1872
Given that the age of the middle child is the average of the ages of the other two children, we can write:
B = (A + C) / 2
Now we have a system of two equations:
A * B * C = 1872
B = (A + C) / 2
We can substitute the value of B from the second equation into the first equation:
A * ((A + C) / 2) * C = 1872
Simplify the equation:
A * (A + C) * C = 3744
Now, we have a quadratic equation in terms of A and C.
[tex]A^2 * C + AC^2 = 3744\\AC(A + C) = 3744\\AC^2 + AC^2 = 3744\\2AC^2 = 3744\\AC^2 = 1872\\C^2 = 1872 / A[/tex]
Since the ages are positive integers, we need to find a pair of positive integers A and C such that [tex]A * C^2 = 1872[/tex].
Let's look for factors of 1872 that can work for [tex]C^2[/tex]:
[tex]1872 = 2^4 * 3^2 * 13[/tex]
The possible pairs of A and C are:
A = 1, C = 1872
A = 2, C = 936
A = 3, C = 416
A = 4, C = 234
A = 6, C = 104
A = 8, C = 58
A = 12, C = 26
Since A and C are ages, we'll choose A = 12 and C = 26.
Now we can find B using the equation B = (A + C) / 2:
B = (12 + 26) / 2 = 38 / 2 = 19
The sum of their ages is:
A + B + C = 12 + 19 + 26 = 57
Therefore, the sum of their ages is 57.

Step-by-step explanation:
Initial value is the y-intercept:
b = 1200Rate of change is the difference in the charge amount per year:
m = (1350 - 1200) / (8 - 5) = 150 / 3 = 50The equation would be:
y = 50x + 1200Initial value
b=1,200
Rate of change is the difference in the charge amount per year:
m = (1,350 - 1,200) / (8 - 5) = 150 / 3 = 50
The equation would be:
y = 50x + 1200

Which statement describes the end behavior of the function?
f(x)= x squared-4/x squared-9
ОА.
The function approaches O as x approaches - and co.
OB.The function approaches 4/5 as x approaches -- and co.
OC. The function approaches 2/3 as x approaches - and co.
OD. The function approaches 1 as x approaches -co and co.
Answer:
D. The function approaches 1 as x approaches [tex]-\infty[/tex] and [tex]\infty[/tex]
Step-by-step explanation:
When evaluating end behavior, take the limit as the function goes to negative and positive infinity.
When evaluating limits to infinity, terms less than the highest degree are irrelevant:
[tex]\displaystyle \lim_{x\rightarrow \infty}\frac{x^2-4}{x^2-9}=\frac{\infty^2}{\infty^2}=1\\\\\lim_{x\rightarrow -\infty}\frac{x^2-4}{x^2-9}=\frac{(-\infty)^2}{(-\infty)^2}=1[/tex]
Therefore, the function approaches 1 as x approaches [tex]-\infty[/tex] and [tex]\infty[/tex]

Lisa typed a 165-word paragraph in three minutes. Use the ratio table to
determine how many minutes it will take for Lisa to type 55 words.
Answer:
1 minute
Step-by-step explanation:
We can see that Lisa types 165 words in 3 mins.
So she types 55 words in 1 minute.
How did I work that out?
Well, all you really do is [tex]\frac {165}{3}[/tex] which is equal to [tex]\frac{55}{1}[/tex] if you divide top and bottom by 3. Anything divided by 1 is itself.

An angle measures 18.6° less than the measure of its complementary angle. What is the measure of each angle?
Answer:
X = 35.7 Y=54.3
Step-by-step explanation:
Let the 2 angles be called X and Y were X is the smaller angle
we know that both angles are complementary therefore
X+Y=90
X = Y - 18.6 ( Given )
Y - 18.6 + Y = 90 ( substitution)
2Y = 90 + 18.6
Y = 108.6/2
Y=54.3
X= Y-18.6= 54.3-18.6 = 35.7
Check : X + Y = 35.7+54.3=90
