1.sum of three consecutive even numbers is 12 the number are
0,5,7
1,3,8
2,4,6
Answer:
The third number is two more than the second number, so it is x+2+2, or simply x+4. Solve for x by combining like terms. The first number is 2, the second is 4, and the third is 6. When we add them together, we have 2+4+6=12.
Answer:
2,4,6
Step-by-step explanation:
first consecutive even number is X , then X+ 2 and X+4
sum = X + X+ 2 + X +4 = 12 then solve
Given f(x)= x-3 and g(x)= 2x+1
Find (fºg) (-10)
Answer:
- 66
Step-by-step explanation:
Evaluate g(- 4) then substitute the value obtained into f(x) , that is
g(- 4) = - 2(- 4)² = - 2 × 16 = - 32, then
f(- 32) = 2(- 32 - 1) = 2 × - 33 = - 66

- What is the slope of a line parallel to the line whose equation is 8x − 6y = −24. Fully simplify your answer.
Slope of the new line parallel to the line whose equation is 8x − 6y = −24 will be 4/3
What is slope in straight line?
Generally, the slope of a line gives the measure of its steepness and direction. The slope of a straight line between two points says (x1,y1) and (x2,y2) can be easily determined by finding the difference between the coordinates of the points. The slope is usually represented by the letter 'm'.
y-y1=m(x-x1)
Given line,
8x − 6y = −24
6y = 8x +24
y = (8/6)x + 24/6
y = 4/3x + 4
slope, m=4/3
Since, the new line that passes is parallel to the line 8x − 6y = −24, the slope of the new line will be the same.
Therefore, Slope of the new line parallel to the line whose equation is 8x − 6y = −24 will be 4/3

What is 7/8 + 8/45 =
Step-by-step explanation:
1.05277777778
hope it helps!
Answer:
1 19/360
Step-by-step explanation:
What we know:
The addends in this equation are 7/8 and 8/45.
First, find the LCM of 8 and 45. Since 8 and 45 don't have any common factors other than 1, just multiply the two numbers.
8 * 45 = 360
After that, find the equivalent fraction for both addends
7/8 * 45/45 = 315/360
8/45 * 8/8 = 64/360
Then, add the two new fractions together, and simplify if needed.
315/360 + 64/360 = 379/360 = 1 19/360
Write a linear function f with the values f(0) = 8 and f(4) = 20.
Step-by-step explanation:
f(0)=8
Coordinate: (0,8)
y intercept,c: 8
f(4)=20
Coordinate: (4,20)
gradient, m
= (20-8)/(4-0)
=3
Y=mx+c
f(x)=3x+8
f(x)=3x+8 is the linear function f with the values f(0) = 8 and f(4) = 20.
What is Linear Function?A linear function is a function that represents a straight line on the coordinate plane.
The given functions are f(0)=8 and f(4) =20
For f(0)=8
Coordinate: (0,8)
y intercept, c: 8
For f(4)=20
Coordinate: (4,20)
gradient or slope, m when x₁=0,y₁=8,x₂=4, y₂=20
=( y₂-y₁)/(x₂-x₁)
= (20-8)/(4-0)=12/4
=3
The linear equation is in the form, y=mx+c
So f(x)=3x+8, where 3 is the slope and 8 is y intercept.

Answer:
1 mile
Step-by-step explanation:
Step one:
given
total distance = 15miles
Jack walks at a pace of 1.5 miles per hour
after 4 hours he will cover a distance of
1.5*4= 6 miles
Jill walks at a pace of 2 miles per hour
after 4 hours he will cover a distance of
2*4= 8 miles
Step two:
The total distance jack and jill must have covered after 4 hours is
8+6= 14 miles
the distance apart will be 15-14= 1 mile

Which statement is correct?
The circumference of a circle is 13π m. What is the area, in square meters? Express your answer in terms of π π.
Answer:
13×(22/7)whole square
Answer:
42.25π
Step-by-step explanation:
The circumference is the diameter times pi.
This means that 13π/π=13 (the diameter)
The radius is diameter/2, so it is 13/2 which is 6.5
The area is the radius squared times pi
6.5^2 = 42.25
42.25π is the area
