Answer:
The correct linear equation is;
f(x) = 10x + 8
Step-by-step explanation:
To choose the correct linear function, we just need to take a specific point, then substitute in each of the equations given to get the one right
The correct one will be the one in which when the x-value is substituted, we will get the y-value
Let us pick (1,18)
Let us begin testing;
A. f(x) = 10x + 8
f(1) = 10(1) + 8 = 10 + 8 = 18
Let us use another point to test this
The second point is (1.5,23)
f(1.5) = 10(1.5) + 8
= 15 + 8 = 23
Liza’s age is two more than thrice the age of her younger sister.if her sister is 5 years old, how old is Liza?
Answer:
17 years old.
Step-by-step explanation:
sisters age:5
5×3+2=17.
Answer:
Liza is 17 years old.
Step-by-step explanation:
Ley 'x' be the age of Liza's younger sister
As Liza’s age is two more than thrice the age of her younger sisterso the equation of Liza's age will be:
Liza's age = 3x+2
As x = 5 years is Liza's younger sister age
so
Liza's age = 3(5)+2
= 15+2
= 17 years
Therefore, Liza is 17 years old.

Solve: 2.3 = v + 0.47 v = _____
Answer:
2.3=v+0.47v=
We move all terms to the left:
2.3-(v+0.47v)=0
We add all the numbers together, and all the variables
-(+1.47v)+2.3=0
We get rid of parentheses
-1.47v+2.3=0
We move all terms containing v to the left, all other terms to the right
-1.47v=-2.3
v=-2.3/-1.47
v=1+0.83/1.47
Answer:
[tex]v = 1.564[/tex]
Step-by-step explanation:
[tex]1v + 0.47v = 2.3[/tex]
[tex] = > 1.47v = 2.3[/tex]
[tex] = > v = \frac{2.3}{1.47} = 1.564[/tex]
The time, t, required to empty a tank varies inversely as the rate, r, of
pumping. If a pump can empty a tank in 2.5 hours at a rate of 400 gallons per
minute, how long will it take to empty a tank at 500 gallons per minute?
Answer:
2 hours
Step-by-step explanation:
2.5 * 400 = 1000
1000 / 500 = 2

A cylinder has a height of 18 millimeters and a radius of 18 millimeters. What is its volume? Use ≈ 3.14 and round your answer to the nearest hundredth.
Answer:
18312.5mm³
Step-by-step explanation:
Given parameters:
Height of cylinder = 18mm
radius = 18mm
Unknown:
Volume of the cylinder = ?
Solution:
The volume of cylinder is given as;
Volume = π r ² h
Insert the given parameters and solve;
Volume = 3.14 x 18² x 18
Volume = 18312.5mm³

Answer:
x = 35 y = 82
Step-by-step explanation:
all triangles add up to 180
the tick mark shows that 2x = y - 12
2x + 2x + 40 = 180
4x + 40 = 180
4x = 140
x = 35
y - 12 + y - 12 + 40 = 180
2y - 24 + 40 = 180
2y + 16 = 180
2y = 164
y = 82
Check:
40 + 2(35) + (82 - 12) = 180
Solve this equation.
24 + 0.44x = 19 + 1.69x
Answer:
x = 4
Step-by-step explanation:
24 + 0.44x = 19 + 1.69x
24 + 0.44x - 1.69x = 19
-1.25x = 19 - 24
-1.25x = -5
x = 4
Step-by-step explanation:
24 + 0.44x = 19 + 1.69x
24 - 19 = 1.69x - 0.44x
5 = 1.25x
1.25x = 5
x = 5/1.25
= 4

Answer:
-8968680
Step-by-step explanation:
If this is what your looking for if not sorryyyy
87789-8977609-78860 all you have to do is use a calculator(if you can) or do it the old school way. First, what I did was subtract the first two numbers 87789 and 8977609 to get -8889820 and then subtracted 78860 from that to get a total of -8968680.
The graph below shows the distance, y, in miles, of a bird from its nest for a certain amount of time, x, in minutes:
Graph titled Distance Vs Time is shown with Time in minutes along the x axis and Distance from Nest in miles along the y axis. The scale on the x axis shows the numbers 0 to 25 at increments of 5, and the scale on the y axis shows the numbers 1 to 8 at increments of 1. A straight line joins the ordered pairs 0, 3 and 5, 4 and 10, 5 and 15, 6 and 20, 7.
Based on the graph, what is the initial value of the graph and what does it represent? (1 point)
a
3 miles per minute; it represents the speed of the bird
b
0.2 mile per minute; it represents the speed of the bird
c
0.2 mile; it represents the original distance of the bird from its nest
d
3 miles; it represents the original distance of the bird from its nest
Answer:
(d).
Step-by-step explanation:
The y-intercept (0, 3) is initial value of graph ⇒ (d). 3 miles; it represents the original distance of the bird from its nest
Answer:
0.2 mile; it represents the original distance of the bird from its nest

If the hot air balloon rises at the same rate each second, what is the hot air balloon’s rate per second?
200
feet per second
4
feet per second
4 feet per second
−4
feet per second
negative 4 feet per second
−200
feet per second
Answer:
4 ft per second
Step-by-step explanation:
We are given that it takes 50 seconds to go 200 feet
in order to find the ft/second, we divide by 50
50/50=1
200/50=4
so 4 ft/ 1 second

If c varies diráctly as (1 + 1) and c= 8, when r = 3, calculate the value ofr when c= 20.
(4marks)
c = k(r + 1)
8 = k(3 + 1)
8 = 4k
8/4 = k
2 = k
c=2(r + 1)
When c = 20, then
20 = 2(r + 1)
20 = 2r + 2
20 - 2 = 2r
18 = 2r
18/2 = r
9 = r
Therefore, the value of r is 9 when c is 20.

How many 1/8-inch pieces of ribbon can be cut from a piece of ribbon that is 3/4 inch long? *
Answer:
the answer is 6
Step-by-step explanation:
Find what's 1/8 divided by 3/4 in fraction form?
step 1 Address formula, input parameters & values.
Input parameters & values:
1/8 and 3/4
Step 2: change the problem
Remember, always do KCF(Keep,Change,Flip)
First i keep 1/8
1/8 ÷ 3/4
Then I change the sign to multiplication because you need to need to find the answer and simplified it
1/8 x 3/4
Make sure u always flip the other fraction because you are multiplying
1/8 x 4/3
then you do the rest
Step 3:solve
1/8 x 4/3=4/24
Step 4: simplified
24/4=6
Now your answer is 6

Conditional Statement: If two lines are parallel, then they do not intersect. Converse: If two lines do not intersect, then they are parallel. Inverse: If two lines are not parallel, then they intersect. Contrapositive: If two lines intersect, then they are not parallel. Which statements are true? A) Converse and Inverse B) Inverse and Contrapositive C) Conditional Statement and Converse D) Conditional Statement and Contrapositive
Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect.
Two or more lines which have no intersections but are not parallel, known as skew lines.
Option D is correct.
Conditional Statement: If two lines are parallel, then they do not intersect.
Converse: If two lines do not intersect, then they are parallel.
Inverse: If two lines are not parallel, then they intersect
Contrapositive: If two lines intersect, then they are not parallel.
Thus, option (D) Conditional Statement and Contrapositive , is correct.
Converse and Inverse are false because skew lines are a type of lines which are neither parallel nor intersecting in 3D
