the sum of the second and fourth of four consecutive integers is 110
Answer:
The integers: 53, 54, 55, 56
Step-by-step explanation:
Consecutive integers increase by 1, so if x is the smallest one, then the numbers are:
x, x+1, x+2, x+3
the sum of the second and fourth: x+1 + x+3 = 2x+4
so: 2x + 4 = 110 ⇒ 2x = 106 ⇒ x = 53
So the integers we are looking for:
53, 54, 55, 56
If f(x) and r1(x) are inverse functions of each other and f(x)=2x+5 , what is f^-1(8) ?
PLEASE HELP!!
Answer:
3/2
Step-by-step explanation:
Given y = 2x + 5, let's rewrite the equation in terms of x;
y = 2x + 5 => Bring 5 to the other side
2x = y - 5 => Divide either side by 2
x = (y - 5)/2
If we want to take the inverse, simply swap the variable's positions...
We have y = (x - 5)/2
Now let's determine f^-1(8), substituting for "y" provided y is our inverse, f^-1
f^-1(8) = (8 - 5)/2 = 3/2
Solution: 3/2

What is an equation of the line that passes through the point (5,-5) and is parallel to the line x+5y=20
Answer:
y = [tex]-\frac{1}{5}[/tex]x - 4
Step-by-step explanation:
Given parameters:
Coordinates = (5, -5)
Equation of the line, x + 5y = 20
Unknown:
Equation of the line parallel to this= ?
Solution:
To find the equation of the line, we must first understand that parallel lines are lines having the same slope. They do not cross each other at any point.
The equation of any straight line is given as;
y = mx + c
y and x are the coordinates
m is the slope
c is the y- intercept
Now,
x + 5y = 20
Let us find the slope of this line;
5y = -x + 20
Divide through by 5;
y = [tex]-\frac{1}{5}[/tex]x + 4
The slope of the new line is the coefficient of x;
Slope = [tex]-\frac{1}{5}[/tex]
So, let us find the y-intercept of the new line;
-5 = [tex]-\frac{1}{5}[/tex] x 5 + c
-5 = -1 + c
c = -5 + 1 = -4
Now,
y = [tex]-\frac{1}{5}[/tex]x - 4
Answer: y = -(1/5)x - 4

Step-by-step explanation:
Triangle A B C is shown with centroid G. Lines are drawn from each point of the triangle through the centroid and to the midpoint of the opposite side to form line segment A D, line segment B E, and line segment C F. The length of line segment D G is x minus 15 and the length of line segment G A is x + 7.
G is the centroid of triangle ABC.

The length from the vertex to the centroid is twice the length from the
centroid to the midpoint of the opposite side.
x is 37Segment [tex]\overline {DG}[/tex] is 22Segment [tex]\overline {GA}[/tex] is 44Segment [tex]\overline {AD}[/tex] is 66Reasons:
The known parameters are;
The centroid of ΔABC = Point G
Segments [tex]\overline {AD}[/tex], [tex]\overline {BE}[/tex], and [tex]\overline {CF}[/tex] are the medians of ΔABC
Length of line segments [tex]\overline {DG}[/tex] = x - 15
Length of line segments [tex]\overline {GA}[/tex] = x + 7
Required:
The value of x, and lengths of the segments of median [tex]\overline {AD}[/tex]
The median is divided at the centroid of the triangle to ratio 2:1
[tex]Length \ of \ line \ segment \ \overline{GA} = \dfrac{2}{3} \times \overline{AD}[/tex]
Therefore;
[tex]\overline{AD} = \mathbf{\dfrac{3}{2} \times \overline{GA}}[/tex]
[tex]Length \ of \ line \ segment \ \overline{DG} = \mathbf{\dfrac{1}{3} \times \overline{AD}}[/tex]
Therefore;
[tex]\overline{AD} = 3\times \overline{DG}[/tex]
Which gives;
[tex]\dfrac{3}{2} \times \overline{GA} = 3\times \overline{DG}[/tex]
Therefore;
[tex]\dfrac{3}{2} \times (x + 7) = 3\times (x - 15)[/tex]
3·x + 21 = 6·x - 90
21 + 90 = 6·x - 3·x
111 = 3·x
3·x = 111
[tex]x = \dfrac{111}{3} = 37[/tex]
x = 37
[tex]\overline {DG}[/tex] = x - 15
The length of line segment [tex]\overline {DG}[/tex] = 37 - 15 = 22
[tex]\overline {GA}[/tex] = x + 7
Length of line segment [tex]\overline {GA}[/tex] = 37 + 7 = 44
[tex]\overline {AD}[/tex] = [tex]\overline {DG}[/tex] + [tex]\overline {GA}[/tex]
Therefore;
Length of line segment [tex]\overline {AD}[/tex] = 22 + 44 = 66

write an equation of the line passing through the point (8,7) that is perpendicular to the line y+7=-7/17(x+8)
A.y= -7/17x+63/17
B.y=7/17x+7
C.y= -17/7x-87/7
D.y= -17/7x + 7
Plz help asap!!!
Answer:
y= 17x/7 - 87/7
The answer would be C is the slope is positive so I'm assuming it's a typo
Step-by-step explanation:
1.) When a slope is perpendicular that means that you do an opposite reciprocal so -7/17 turns into 17/7
2.) Use point slope form and solve for y
y-y1= m(x-x1)
y-7= 17/7 (x-8)
y-7= 17x/7 - 136/7
y= 17x/7 - 87/7

what is the answer for x+7=2(x-15)
Answer:
x=37 Hope this helped <3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x+7=2(x−15)
x+7=(2)(x)+(2)(−15)(Distribute)
x+7=2x+−30
x+7=2x−30
Step 2: Subtract 2x from both sides.
x+7−2x=2x−30−2x
−x+7=−30
Step 3: Subtract 7 from both sides.
−x+7−7=−30−7
−x=−37
Step 4: Divide both sides by -1
Answer:
[tex]\boxed {x = 37}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]x + 7 = 2(x - 15)[/tex]
-Use Distributive Property:
[tex]x + 7 = 2(x - 15)[/tex]
[tex]x + 7 = 2x - 30[/tex]
-Take [tex]2x[/tex] and subtract it from [tex]x[/tex]:
[tex]x + 7 - 2x = 2x - 2x - 30[/tex]
[tex]-x + 7 = -30[/tex]
-Subtract [tex]7[/tex] to both sides:
[tex]-x + 7 - 7 = -30 - 7[/tex]
[tex]-x = -37[/tex]
-Divide both sides by [tex]-1[/tex]:
[tex]\frac{-x}{-1} = \frac{-37}{-1}[/tex]
[tex]\boxed {x = 37}[/tex]
So, the value of [tex]x[/tex] is [tex]37[/tex].

Write a system of linear equations that has (-4, 8) as the solution. Once you have made your system of equations, solve it algebraically to show that you do indeed get the solution (-4, 8).
Answer:
See below
Step-by-step explanation:
(-4, 8) has to be the solution.
1st equation: -4x+8y = 1
2nd equation: 8x - 4y = 1
These should work. Do the matrix-substitution combo method to see:
-4 8 1
.8 -4 -1
Reduce and and matrix-substitution combo:
1 0 -4
0 1 8
The reduced eckerd form of the matrix shows that the solutions are (-4, 8)
Therefore it -4x + 8u = 1 and 8x - 4y = 1 are the two equations for the system.

Rena’s grandfather opened a savings account as a college fund for her. His initial deposit and the yearly simple interest rate are shown.
A college graduate is shown walking up stairs. The bottom step represents three thousand five hundred dollars. The value of the top step is unknown. The distance up the stairs is labeled four years. The simple interest rate is three point two five percent.
How much will Rena have in this account after 4 years?
Enter the correct answer in the box.
Answer:
Total amount (A) = $3,955
Step-by-step explanation:
Given:
Initial deposit (P) = $3,500
Rate of interest (r) = 3.25%
Number of years (t) = 4
Find:
Total amount (A)
Computation:
Simple interest = (p)(r)(t)
Simple interest = (3,500)(3.25)(4)
Simple Interest = $455
Total amount (A) = Initial deposit (P) + Simple Interest
Total amount (A) = 3,500 + 455
Total amount (A) = $3,955

The value of [b] if a = 1/8 and c = 4 will be 33/16.
What is the mean of two numbers?
The mean of two numbers [a] and [b] is -
[M] = (a + b)/2
Given is that a = 1/8 and c = 4.
We have the following values -
a = 1/8
c = 4
Therefore, we can write the value of [b] as -
b= (1/8 + 4)/2
b = (33/8)/2
b = 33/8 x 1/2
b = 33/16
Therefore, the value of [b] if a = 1/8 and c = 4 will be 33/16.
