Answer:
y = 1/3x + 26/3
Step-by-step explanation:
Original equation: y = -3x + 2
Perpendicular lines have the "opposite reciprocal" slopes of each other, meaning you flip the numbers and reverse the sign.
Slope of original equation: -3
Slope of perpendicular line: 1/3
How: Reciprocal, flip the numbers: -3/1 to -1/3, then reverse sign -1/3 to 1/3
Then you substitute (-2, 8) into the new equation: y = 1/3x + b
*there's b because you don't know the y-intercept yet
Substitute: 8 = 1/3(-2) + b
8 = -2/3 + b
Add 2/3 on both sides
b = 24/3 + 2/3
b = 26/3
*this is the y-intercept
Therefore, the perpendicular equation is: y = 1/3x + 26/3
Find the measure of the angle indicated in bold (18x)
Answer:
x=5
Step-by-step explanation:
That is a right angle, so 18x=90. To find x, you have to divide 90 by 18, which gives you 5.

What is the account balance if the principle is $350 the annual rate is 4% and the time is 3 years.
Answer:
393.70
Step-by-step explanation:
350x.04= 14 for 1st year
350+14= 364 for 1st year
364×.04= 14.56 for 2nd year
364+14.56= 368.56 for 2nd year
368.56×.04= 15.14 for 3yr
368.56+15.14= 393.70 yr 3 yrs
Answer:
The answer is 42.
Step-by-step explanation:
We start by using the Simple Interest Formula.
I=P x R x T
Key
P: Principal, R: Rate and T: Time
>P=$350
>R=4% or .04
>T= 3 (for 3 years)
Finally, multiply everything (350)(.04)(3)
| I= 42 |
Lines x and y are parallel. Write an equation that represents the relationship between b and e. Explain how you know this equation is always true. Your explanation should use AT LEAST TWO of the following terms: vertical angles, corresponding angles, congruent, supplementary.
please help
Answer:
m∠b + m∠e = 180°
Step-by-step explanation:
Lines x and y are the parallel lines and a transversal line is intersecting these lines.
∠b ≅ ∠h [Vertical angles]
∠h ≅ ∠f [Corresponding angles]
Therefore, ∠b ≅ ∠f [Congruent angles]
m∠f + m∠e = 180° [Supplementary angles]
m∠b + m∠e = 180° [Since, ∠b ≅ ∠f]
Therefore, equation representing the relation between ∠b and ∠e is,
m∠b + m∠e = 180°
The required equation that represents the relationship between b and e is m<b + m<e = 180
From the given diagram, we can see that the line x and y are cut by a transversal. This shows that the following statements are true;
m<b and m<g are supplementary i.e m<b + m<g = 180
Also m<b and m<f are equal (alternate interior angle)
m<b = m<d (vertically opposite angle)
Also, since m<d and m<e are supplementary angles (angle on a straight line), then m<b and m<e are also supplementary
Hence the required equation that represents the relationship between b and e is m<b + m<e = 180

Garcia's Grill offers 7 side dishes, 5 types of steak, and 8 toppings. How many different smothered steak dinners can be made if a smothered steak dinner consists of the customer's choice of steak served with 3 different toppings and 4 different side dishes?
Answer:
The number of smothered steak dinners that can be made is 9,800
Step-by-step explanation:
A smothered steak dinners consist of customer’s choice of steak with 3 different toppings and 4 different side dishes.
What this means is that;
Customer will select 1 steak out of 5 types
3 toppings out of 8
4 out of 7 side dishes
Thus, the number of steak dinners would be;
5C1 * 8C3 * 7C4
= 5 * 56 * 35 = 9,800

Solve the compound inequality 2x − 3 < 7 and 5 − x ≤ 8. A. x ≥ 3 and x < 2 B. x ≥ 3 and x < 5 C. x ≥ −3 and x < 2 D. x ≥ −3 and x < 5
Given:
The compound inequality [tex]2x-3 < 7[/tex] and [tex]5-x \leq 8[/tex].
To find:
The solution for the given compound inequality
Solution:
We have, compound inequality [tex]2x-3 < 7[/tex] and [tex]5-x \leq 8[/tex].
For [tex]2x-3 < 7[/tex],
Add 3 on both sides.
[tex]2x < 7+3[/tex]
[tex]2x < 10[/tex]
Divide 2 on both sides.
[tex]x< 5[/tex] ...(i)
For [tex]5-x \leq 8[/tex],
Subtract 5 from both sides.
[tex]-x \leq 8-5[/tex]
[tex]-x \leq 3[/tex]
Divide both sides by -1. So, the sign of inequality is changed.
[tex]x \geq -3[/tex] ...(ii)
Using (i) and (ii), we get the solution of given compound inequality as
[tex]x \geq -3[/tex] and [tex]x< 5[/tex]
Therefore, the correct option is D.

The point-slope form of the equation of the line that passes through (-9, -2) and (1, 3) is y – 3 = {(x - 1). What is the
slope-intercept form of the equation for this line?
Oy=1x+2
Oy={x-4
O y = x + 3/2
Oy=2x-
2.
Option A is the correct answer, y = x + 2
y - 3 = x-1
If you bring the 3 to the R.H.S, it becomes y = x + 2
If you substitute the values,
3 = 1 + 2
3 = 3
Thus, e equation is correct
The slope-intercept form of the equation for this line is y = 1/2 x + 5/2
First, we need to get the slope of the equation passing through the coordinate (-9, -2) and (1, 3)
m = 3+2/1+9
m = 5/10
m = 1/2
The equation in point slope form is given as y - 3 = 1/2(x - 1)
2(y - 3) = x - 1
Write in slope intercept form
2(y - 3) = x - 1
2y - 6 = x - 1
2y = x + 5
y = 1/2 x + 5/2
Hence the slope-intercept form of the equation for this line is y = 1/2 x + 5/2

Answer:
f(2) = -5
Step-by-step explanation:
For this problem, we are evaluating the graph of f(x), meaning at the value of x, we want the y-value.
Note, when x = 2 on the graph, the only y coordinate available is y = -5.
Hence, when we evaluate f(x) for x = 2, we get y = -5. f(2) = -5.

Let's see what to do buddy...
_________________________________
Step (1)
We know that the sum of the interior angles of any n-sided figure is obtained from the following equation :
[tex](n - 2) \times 180[/tex]
Our figure has 5 sides ;
So , sume the interior angles of it equals :
[tex](5 - 2) \times 180 = 3 \times 180 = 540 \\ [/tex]
_________________________________
Step (2)
First look at the photo which I post.
According it we have :
[tex](180 - x) + 120 + 85 + (2x - 10) + 90 = 540 \\ [/tex]
[tex]2x - x + 475 - 10 = 540[/tex]
[tex]x + 465 = 540[/tex]
Subtract the sides of the equation minus 465 :
[tex]x = 540 - 465[/tex]
[tex]x = 75[/tex]

And we're done.

im failing Geometry if anyone is good at Geometry and want to help me i attached 5 problems i greatly appreciate anyone that helps
Answer:
x = 12
Step-by-step explanation:
Here we go!
What we know:
So 7x and 8x are part of a same side interior angle. meaning, they add up to 180°!
[tex]8x + 7x = 180[/tex]
Combine like terms
[tex]15x = 180[/tex]
Divide 15 from both sides
[tex]x = 12[/tex]
Let's check our work:
plug in x
7(12) + 8(12) = 180
multiply
84 + 96 = 180
add
180 = 180
