Blake knows that one of the solutions to x2 – 6x + 8 = 0 is x = 2. What is the other solution?
x = –6
x = –3
x = 4
x = 8
Solve for x
9 (x +2) < 3(3-5)
Step-by-step explanation:
9x+18 < 9-15
1)9-15= -6
9x+18 < -6
9x+18= -5
9x= (-5) - 18
9x= -23
x= 23/9=2 5/9
X=2,55556
Which linear equation is best represented by the graph?
Answer:
y=2/3x-2
Step-by-step explanation:
A linear equation is in the form of y=mx+b
You need to find the slope and y-intercept.
The slope is 2/3 Up 2, over 3 to the right.
The y-intercept is (0,-2)
So the equation would be, y=2/3x-2

Answer:
x = 21
Step-by-step explanation:
The angle T is an exterior angle to the ∆RST, so will be equal to the sum of the remote interior angles:
T = 4x° +2x° = 6x°
T is also a same-side exterior angle with the one marked 54°, so is supplementary to that:
T + 54° = 180°
6x° + 54° = 180°
x + 9 = 30 . . . . . . . . divide by 6

Their sum is 84° +42° +54° = 180° . . . as it should be.
To make 5 gallons of cleaning solution, 3 cups of bleach is mixed in with water.
Which table shows the relationship between the gallons of cleaning solution made and the cups of bleach used?
Answer:
Option B.
Step-by-step explanation:
Let 'g' represent the number of gallons of cleaning solutions.
Let 'c' represent the number of cups of bleach.
From the question given above, we were told that:
To make 5 gallons of cleaning solution, 3 cups of bleach is mixed in with water.
This implies that number of gallons (g) of the cleaning solution is directly proportional to the number of cups (c) of the bleach mixed with water i.e
g ∝ c
g = Kc
K is the constant of proportionality.
Next, we shall determine the relationship between g and c as follow
g = 5
c = 3
K =?
g = Kc
5 = K × 3
Divide both side by 3
K = 5/3
g = Kc
K = 5/3
g = 5/3 c
Thus, the relationship between g and c is:
g = 5c / 3
Next, we shall make c the subject of the formula. This is illustrated below:
g = 5c / 3
Cross multiply
3g = 5c
Divide both side by c
c = 3g/5
Next, we shall determine c when g = 10, 15, and 20.
This is illustrated below:
g = 10
c =?
c = 3g/5
c = (3 × 10)/5 = 30/5 = 6
g = 15
c =?
c = 3g/5
c = (3 × 15)/5 = 45/5 = 9
g = 20
c =?
c = 3g/5
c = (3 × 20)/5 = 60/5 = 12
Summary:
Num. of gallon (g) >> Num. of cup (c)
5 >>>>>>>>>>>>>>>> 3
10 >>>>>>>>>>>>>>> 6
15 >>>>>>>>>>>>>>> 9
20 >>>>>>>>>>>>>>> 12
Therefore, option B gives the correct table.

It takes you 7 minutes to do 2 math problems. How long will it take you to do one of Mr. Bruno’s homework assignments with 27 questions?
Answer:
94.5 minutes or 1 hour and 34.5 minutes
Step-by-step explanation: If it takes you 7 minutes for 2 math problems then that means it takes you 3.5 minutes for one problem. Then you multiply it by 27 and you get 94.5 minutes you can convert it into 1 hour and 34.5 minutes if you want.
If P=2L+2W, solve for W.
Answer:
W = (P-2L)/2
Step-by-step explanation:
Isolate W
P = 2L + 2W
subtract 2L from each side
P - 2L = 2W
divide each side by 2
(P-2L)/2 = W
Write an equation of the line in slope-intercept form f(0)=2,f(2)=4
Answer: y=2x-2
Step-by-step explanation: First you plot those two points and make a line, then find the rest below. Slope formula is y=mx+b. M is the slope, rise over run, which is 2, and b is the y-intercept, where it meets the y-axis, which is -2.

What is an equation in slope intercept form of a line that passes through points (0,5) and (4,0)
Answer:
y = -5/4x + 5
Step-by-step explanation:
If you use rise/run it rises down 5 and runs to the right 4, therefore your slope is -5/4x and for your Y-intercept its 5 because (0,5) is already on the Y-axis, so your answer is y = -5/4x + 5
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\ m=\frac{0-5}{4-0} \\m=\frac{-5}{4} \\m=-\frac{5}{4}[/tex]
Therefore the slope is m = -5/4
Find the equation
Let [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
Substitute m = -5/4 in the equation,
[tex]y=-\frac{5}{4}x+b[/tex]
Substitute any ordered pairs that are given. I'll use (4,0) instead.
Substitute y = 0 and x = 4
[tex]0=-\frac{5}{4}(4)+b\\ 0=-5+b\\5=b\\[/tex]
Thus, the y-intercept is 5 (b is 5)
Therefore, the equation is [tex]y=-\frac{5}{4}x+5[/tex] #

Mr. Bell wants to plant a rectangular garden in his backyard. He has 100 feet of fence to
enclose his garden. He wants the length to be 5 feet more than the width. What are the
dimensions, in feet, of the garden?
What is the total LENGTH in feet?
Answer:
The dimensions of the garden are 22.5ft by 27.5ft
Step-by-step explanation:
Here, we want to calculate the dimensions of the garden.
let the length be x ft
we are told that the he wants the length to be 5 feet more than the width;
That means the width will be (x-5) ft
Mathematically;
Since the shape is rectangular, the perimeter will be 2( l + w)
Thus; 2(x + x-5) = 100
2(2x-5) = 100
divide both sides by 2
2x-5 = 50
2x = 50 + 5
2x = 55
x = 55/2
x = 27.5 ft
The width is thus; 27.5ft - 5ft = 22.5ft
the dimensions of the garden are 27.5 ft by 22.5 ft

The sum of three consecutive number is 54
Find the first two
number.
a = 17
b = 18
c = 19
Step-by-step explanation:Hi there !
a + b + c = 54
b = a + 1
c = a + 2
replace b ; c
a + (a + 1) + (a + 2) = 54
3a = 54 - 3
3a = 51
a = 51 : 3
a = 17
b = 18
c = 19

H is the circumcenter, or point of concurrency, of the perpendicular bisectors of ΔACE.
Triangle A C E is shown. Point H is the circumcenter of the triangle. Lines are drawn from each point of the triangle to point H. Lines are drawn from point H to the sides of the triangle to form right angles. Line segments H B, H F, and H D are formed.
Which statements must be true regarding the diagram?
Answer:
∠HDC ≅ ∠HDE, AB ≅ BC, HC ≅ HE
Step-by-step explanation:
yup
The circumcenter describes the point of intersection of three perpendicular bisectors. Any point on the perpendicular bisector is equidistant from the endpoint of the segment. Hence, the true statements are :
HC ≈ HE∠HDC ≈ ∠HDEAB = BCThe intersection point H is equidistant from the vertices of the triangle A, C and E
Therefore, HA ≈ HC ≈ HE ; Hence, the expression ;
HC ≈ HEB is the midpoint of the line AC ; Hence, using the midpoint rule ; AB = BC
∠HDC ≈ ∠HDETherefore, only the three statements are true.

Which of the following is the valid classification of the system given below?
$ 7x + 2y = 24
| 2x + 1 = y
Answer:
Step-by-step explanation:
The system of equation given is a simultaneous equation
7x + 2y = 24 ...... 1
2x + 1 = y ......... 2
Rearrange
7x + 2y = 24 .... *1
| 2x - y = -1 ..... * 2
Use elimination method
7x + 2y = 24
4x - 2y = -2
add
7x+4x = 24-2
11x = 22
x = 22/11
x = 2
Substitute x = 2 into 2
2x+1 = y
y 2(2)+1
y = 4+1
y = 5
Hence x = 2, y = 5
The system of equation is a simultaneous equation
The perimeter of the square kitchen floor measures 48 feet what is the area of the kitchen floor
Answer:
the answer is 144 feet
Step-by-step explanation:
to find the how long each sides of the square is divide 48 by 4 (because that's how many sides there are on a square). by doing that you get 12
to find the area of the square you do A= lw which in this case it would look something like this:
A= 12(12) you use 12 twice because square sides are always equal
then you multiply which gives you A= 144

Which value of n makes this equation true?
3n + 3/5 = 5n-1/9
A.
n=-16
B.
n=-2
c.
n= 2
D
n = 16
The value of n makes this equation true is -16.
How can we find the solution to an equation?We do same operations on both the sides so that equality of both expressions doesn't get disturbed. Solving equations generally means finding the values of the variables used in it for which the considered equation is true.
Sometimes we can find such value, and sometimes it is not possible at all, or sometimes, there are infinite number of solutions.
WE have been given an expression as;
3n + 3/5 = 5n-1/9
Combine the like terms;
3n + 3/5 = 5n-1/9
3n - 5n = -3/5 -1/9
-2n = -27 - 5 / 45
n = -16
The value of n makes this equation true is -16.
