Point H is on the line segment GI. Given HI=6x, GH=x^2+5x and GI 7x+21. Find the values of x and determine the length of HI.
Answers
Answer:
x=3
HI=18
Step-by-step explanation:
Equations
Suppose a segment with endpoints G, I. Somewhere in between lies point H, in such a way that:
GI = GH + HI
Every segment is given as an expression with variable x:
[tex]HI=6x[/tex]
[tex]GH=x^2+5x[/tex]
[tex]GI=7x+21[/tex]
Substituting:
[tex]7x+21=x^2+5x+6x[/tex]
Moving everything to the right side:
[tex]0=x^2+5x+6x-7x-21[/tex]
Swapping sides and simplifying:
[tex]x^2+4x-21=0[/tex]
Factoring:
[tex](x+7)(x-3)=0[/tex]
Solving, we have two possible solutions:
x=-7, x=3
The negative solution is discarded because it would result in negative lengths. Thus the solution is
x=3
Determine the length of HI:
HI=6x=6*3=18
HI=18

The m∠ 13 = 29x - 2 and the m∠ 9 = 27x + 6
What is the m∠ 12?
Answers
Answer:
x=4
m<12 = 66
Step-by-step explanation:
Answer:
x = 4
m∠12 = 66
m∠13 and m∠12 are linear pairs (supplementry angles)
Step-by-step explanation:
m∠9 ≈ m∠15 (Vertical angle)
m∠15 ≈ m∠13 (Corresponding angle)
m∠9 ≈ m∠13
29x - 2 = 27x + 6
2x - 2 = 6
2x = 8
x = 4
m∠13 = 29(4) - 2
m∠13 = 114
m∠13 + m∠12 = 180
180 - m∠13 = m∠12
180 - 114 = 66
m∠12 = 66

1. A line goes through the points (0,7) and (1,9). Write the following equation forms:
Point-Slope Form (using the point (1,9):
Slope-Intercept Form:
Standard Form:
2. Write the following equation forms given that f(−3)=4 and f(−1)=−4 are true of the line: Slope-Intercept Form:
Standard Form:
Answers
So the options are in y=mx+b aka slope intercept form, so since the slope is 1/2, and passes through (2,-3) the equation will be y=1/2x+2. So the answer is y = one-half x + 2.
Where m=slope
Y1 is any y value from a point on the graph
X1 any x value from the same point on the graph
The first thing to do is find the slope
M= (9-7)/(1-0)=2/1=2
Next is to sun in values
the point given is (1,9)
So we put 9 in place of y1 and 1 in place of x1
So the line in point slope form is
Y-9=2(x-1)
Y intercept formula: y=mx+b
The only new letter is b which is the y intercept value (0,b)
The y intercept is the point where x is 0 which the problem says is (0,7)
So, keeping the same slope
The answer is
Y=2x+7
Standard form: Ax+By=C
Where A,B, and C are integers (can’t be fractions)
If you reorder the slope intercept form
You get
-2x+y=7
You have to flip the signs because a needs to be positive
So the answer is
2x-y=-7
2)
When you see something like f(-3)=4
That is saying when x is equal to -3, the whole equation is equal to 4
So f(x)=n
So when x is -3, y is 4 and when x is -1, y is -4
M=(4+4)/(-3+1)=8/-2=-4
Sub in points to find b
4=-4(-3)+b
4=12+b
b=-8
So,
Y=-4x-8
Std form
Move -4x to the left with addition to get
4x+y=-8

The jazz band has m(variable) members. To raise money for a tour, each member sold 12 raffle tickets. Write an expression that shows the number of raffle tickets sold.
Answers
Answer: 12m
Step-by-step explanation:
Each member sells 12 tickets, so you would have to multiply the amount of tickets(12) by the amount of members(m).
=============================================
Explanation:
1 person sells 12*1 = 12 tickets
2 people sell 12*2 = 24 tickets
3 people sell 12*3 = 36 tickets
....
m people sell 12*m = 12m tickets
m is a placeholder for a positive whole number (1,2,3,...)

now you know that each side is 9, so 6x-3=9
when you solve that, x=2
4(6x-3)= 36

For 6 chairs, 72 screws and for 9 chairs, 108 screws.
Step-by-step explanation:
So, for every 2 chairs, he needs 24 screws.
By Unitary Method,
We get screws needed for one chair, that is, 24/2 = 12 screws for one chair.
So, for 6 chairs,
6 × 12 = 72 screws.Similarly, for 9 chairs,
9 × 12 = 108 screws.Answer:
The ratios to this would be:
[tex]\left[\begin{array}{ccc}2&24\\6&72\\9&108\end{array}\right][/tex]
Step-by-step explanation:
Ratios are similar to fractions, in some ways, ratios are to show the relation between two numbers, such like a proportion:
For example:
4:3
or the ratio of men' jobs to women's' is 8 to 1 (8:1)
In this case, it is said that:
Gary needs 24 screws for every 2 chairs.
The ratio of this is 24: 2
Also meaning:
[tex]\frac{24}{2}[/tex]
and [tex]2\sqrt{24}[/tex], the quotient is = 13
Now we multiply 12 to '6' and '9'
You will get:
12(6) = 72
12(9) = 108
This will be your answer.

In a group of 45 students at a school, all students must study at least one science. Physics is compulsory, but students may also opt to study chemistry or biology or both. 9 students take all three sciences. 24 take both physics and biology (with or without chemistry). 12 students take only physics. How many are studying chemistry and physics but not biology?
Answers
Answer:
9 students
Step-by-step explanation:
Let x be the number of students taking only Physics and Chemistry
Number of students :
All 3 sciences = 9
Only physics = 12
Both Physics and Biology( without Chem ) = 24 -9 = 15
15+ 9 + 12+x = 45 , since Physics is compulsory
36 + x = 45
x = 45 - 36
x = 9

The red dot is located between 12 and 13. The red dot is about half way between 12 and 13, but a little below the half way point, so the red dot represents a little below half way between the two square roots. Since the square root of 144 is equal to 12 and the square root of 169 is equal to 13, then the red dot is located between the two square roots. By extension, to the nearest integer, the approximate value of the dot will be a little below half way between and , which is about the square root of .
Answers
Answer:
The answer is "156".
Step-by-step explanation:
According to the question, the 144 square root equals 12. The 169 square root equals 13, and by extending the estimated price of blackness, only at the nearest entry, has been a little or less halfway between both the 144 square root and the 169 square root estimated, at 156 square root, that's why 156 is the correct answer.

Answer:
x = 12 and y = 24 Can I get brainiiest
Step-by-step explanation:
We know (3x + 34) and (2x + 46) are vertical to each other so they equal the same measure. We will solve it like this.
3x + 34 = 2x + 46 (subtract 34 on each side)
3x = 2x + 12 (subtract 2x on both sides)
x = 12
Now plug in
3(12) + 34 = 2(12) + 46
36 + 34 = 24 + 46
70 = 70
Now all you have to do is do the other pair of angle
4y + 14 + 70 = 180 (we are using what we already know about 70)
(collect like terms)
4y + 84 = 180 (subtract 84 on both sides)
4y = 76 (divide by 4)
y = 24
(plug in)
4(24) + 14 = 6(24) - 34
96 + 14 = 144 - 34

Answer:
with 2 sides, we can assume that the 25 inch side is the hypotenuse.
7^2 + 25^2 = 49 + 625 = 674
674 is NOT a perfect square so we'll make the 25 side as the hypotenuse.
7^2 +n^2 = 625
n^2 = 625 - 49
n^2 = 576
square root (576) = 24
So the 3 sides are
7 24 and 25
