a )
[tex]angle \: 4 = 62°[/tex]
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
b )
[tex]8x + 6 = 62[/tex]
Subtract sides 6

Answer:
4 = 15.5 degrees
Explanation:
180 degrees - 118 degrees = 62 degrees
62/4= 15.5 degrees
Answer:
x = 7 degrees
Explanation:
8x+6=62
62-6=56
8x=56
x=7

Given: AC and BD bis, each other.
Prove: ABCD is a parallelogram
Answer:
because AC and BD bis => AX = XC; BX = XD
ΔAXD ≅ ΔCXB (SAS) because: AX = CX
DX = BX
m∠AXD = m∠BXC ( 2 opposing angles)
because ΔAXD ≅ ΔCXB (SAS)
=> AD = BC and m∠DAX = m∠BCX
because m∠DAX = m∠BCX => AD//BC
ABCD has AD = BC and AD//BC => ABCD is a parallelogram
Step-by-step explanation:
Write the equation in slope-intercept form through the point (-5, 3) and is perpendicular to the line y = 2x - 3 and graph
Slope intercept form: y = mx + b
When a line is perpendicular to another line, its slope is the negative reciprocal to that slope.
From this information, we already know that the slope of our new line is -1/2, because -1/2 is the negative reciprocal to 2 (which is the slope of the original line).
y = -1/2x + b
Because the point (-5,3) is given, we can simply plug the x and y coordinates into our incomplete equation.
3 = -1/2(-5) + b
3=2.5 + b
b = 0.5
ANSWER: y = -1/2x + 0.5
THE GRAPH IS LINKED; RED LINE IS y=2x-3 AND BLUE LINE IS y=-1/2x + 0.5
Find the slope from the points given:
(18, -5), (18, 20)
Answer:
UNDEFINED
Step-by-step explanation:
change in y over the change in x is how you'd find slope, however, x is the same in both of these, making this a limitation not an equation, therefore the slope is undefined 18-18 = 0 -> Anything divided by zero as a slope is undefined.
Rearrange the area formula to solve for |
A=lw
Answer: L=A/W
Or you can plug in the values for Area and width.
Step-by-step explanation:
If you divide the total area by the width, you get the length
A: 400
L: ?
W: 50
400=50L
400/50=50L/50
8=L
L=400/50
L=8

Find the slope of the line through the pair of points.
(17,-7) and (13,-4)]
Answer:
3/4
Step-by-step explanation:
(17,-7) And (13,-4). First take -4 and subtract it from-7. When you do that you get 3. Then Subtract 13-17. You get 4. Write 3 and 4 as a fraction. 3/4. The 3 is the x-value and the 4 is the y value. So 3/4 is your slope

what is the solution to this problem? 2x+3(x-10)=45
Answer:
x= 15
Step-by-step explanation:
2x+3(x-10)=45
2x+3x-30=45
Combine like terms:
2x+3x-30 turns into 5x-30= 45
5x-30=45
+30 +30
5x = 75
x = 15
Answer:
x = 15
Step-by-step explanation:
2x+3(x-10)=45
2x+3x-30 =45
5x-30 =45
5x =45+30
5x =75
x =75/5
x =15
Um I don’t really understand math. But I have a test and I need to. know what is the least common multiple of 15 and 45 but can u show your work plz and thank you

If the perimeter of a triangle is 7x + 13, and two sides measure -6x + 12 and 5x – 5. Find the missing side.
Answer:
6x+20
Step-by-step explanation:
7x+13= (-6x+12) + (5x-5) + y
7x+13= -1x+ 7 + y
6x+20=y
I hope im right!
5. Which of the following equations would
have no solutions?
A. 10x + 3 = 3 + 10x
B. -8 + 16x = 16x - 8
C. 4(2x - 3) = 8x - 12
D. 12 - 6x = -6x - 12
Answer:
D
Step-by-step explanation:
for A if you subtract 3 from both sides and divide by 10 from both you get x = 0 so that has infinate solutions
for B you add 8 to both sides and divide by 16 getting the same thiong as A
For C you ditribut 4 to 2x and -3 getting 8x-12=8x-12 if you solve it you get the answer as A & B
For D if you subtract 12 from one side you get -6x = -6x -12 (-12)
causing you not to be able to solve it

Use the scenario below to answer questions 2 - 4
A Tech Software salesperson earns a base salary of $40,000 plus a commission of $3000 for every subscription to the software they sale.
2. Write an equation, in slope-intercept form, that shows the total amount of income the salesperson earns if he sells x subscriptions in a year.
3. What does the y-intercept of the equation represent in the context of the problem?
a) the base salary of the salesperson
b) the total salary of the salesperson per year
c) the amount of money the salesperson makes per software sale.
d) none of these
4. What does the slope of the equation represent in the context of the problem?
a) the commission per subscription
b) the total amount of money the salesperson makes
c) a one time, yearly commission for all the subscriptions
d) the base salary of the sales person
WANT A EXTRA 10 PTS?
comment on this and ill make another problem for 10 pts!
Answer:
y = 3000x + 40000a) the base salary of the salespersona) the commission per subscriptionStep-by-step explanation:
Slope intercept form is found by [ y = mx + b ] where m = slope and b = y-intercept. We are given that a salesperson gets $40000 as a base salary. Since this value doesn't change it is the starting value, in other words the y-intercept. The salesperson also gets $3000 for every subscription they sell. Since this amount grows at a constant rate, that is the slope. Now, we can write the slope intercept form of [ y = 3000x + 40000 ].
Best of Luck!
Answer:
1. y = 3000x + 40000
2. Option A: base salary of the salesperson
3. Option A: the commission per subscription
Step-by-step explanation:
1. The commission of $3000 will be the first number, then will come the salary. Now, since it has to be in slope form, it is on the y-intercept, so we write y.
2. It is the base salary because it is the only number that does not have a missing value, 3000x does.
3. The commission per subscription is the answer because the context of the whole slope is the commission per subscription. Question 2 was the y-intercept.
