12. Which line has an x-intercept of -1 and a
y-intercept of 1?
A. y = -x
B. x - y = 1
C. x - y = -1
D. x + y = 1
Answer:
#4
Step-by-step explanation:
1) The y intercept is 0.
2) Convert to slope-intercept form:
2x + 3y = 12
3y = -2x + 12
y = -2/3 x + 4
So the y-intercept is 4.
3) Write in point-slope form:
y + 4 = 2 (x - 1)
Now convert to slope-intercept form:
y + 4 = 2x - 2
y = 2x - 6
So the y-intercept is -6.
4) The y-intercept is 5.
So of the four lines, #4 has the largest y-intercept.
The line with an x-intercept of -1 and a y-intercept of 1 is C. x - y = -1
A linear equation is of the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept
Given the line x - y = -1, the x intercept is at y = 0, hence:
x - 0 = -1
x = -1
The y intercept is at x = 0, hence:
0 - y = -1
y = 1
The line with an x-intercept of -1 and a y-intercept of 1 is C. x - y = -1

Find the value of x in each case:
Answer:
x=19°
Step-by-step explanation:
Angles ∡DBE ≅ ∡ACD= 3x reason - angles with parallel arms
Angles ∡ADC and ∡ADB=95° are supplemental angles which means
∡ADC + ∡ADB=180° => ∡ADC = 180° - ∡ADB= 180°-95°= 85°
In the triangle we have ∡ADC + ∡ACD + ∡CAD = 180° =>
85 + 3x + 2x = 180 => 85 + 5x = 180 => 5x= 180-85 => 5x=95
x=95/5 => x=19°
Good luck!!!

0.7(3s+4)−1.1s=7.9 I need a answer
First, expand the bracket
2.1s + 2.8 - 1.1s = 7.9
Next, collect like terms
s + 2.8 = 7.9
Lastly subtract 2.8 from 7.9 to get your answer.
s = 5.1
(Hope this helps! ^^)
Answer:
[tex]\boxed {s = 5.1}[/tex]
Step-by-step explanation:
Solve for the value of [tex]s[/tex]:
[tex]0.7(3s + 4) - 1.1s = 7.9[/tex]
-Use Distributive Property:
[tex]0.7(3s + 4) - 1.1s = 7.9[/tex]
[tex]2.1s + 2.8 - 1.1s = 7.9[/tex]
-Combine like terms:
[tex]2.1s + 2.8 - 1.1s = 7.9[/tex]
[tex]s + 2.8 = 7.9[/tex]
-Subtract [tex]2.8[/tex] to both sides:
[tex]s + 2.8 - 2.8 = 7.9 - 2.8[/tex]
[tex]\boxed {s = 5.1}[/tex]
So, the value of [tex]x[/tex] is [tex]5.1[/tex].

factors of 30=1,2,3,5,6,10,15,30
factors of 48= 1,2,3,4,6,8,12,16,24

A $240 suit is marked down by 10% what the sale price
Sales price of suit is equals to $216 after applying 10% discount.
What is discount?
" Discount is deduction by some percent or amount in the original price of any product."
Formula used
Sales price = Marked price - discount amount
Discount = ( Marked price × discount %) /100
According to the question,
Marked price of the suit= $240
Discount % on the suit =10%
Substitute the value in the formula we get,
Discount = (240 × 10) / 100
= $24
Sales price = $240 - $24
= $216
Hence, Sales price of suit is equals to $216 after applying 10% discount.

Can anybody help me on this math question for number 3 and Find the measure of each interior angle of the regular polygon?
Answer:
the measure of each angle is 150.
Step-by-step explanation:
in order to find this you need to find the measure all the degrees which can be found with (n-2)x180
in this case this is (12-2) x 180
so you would get the total degrees in the inside is 1,800
then there are a total of 12 interior angles so divide 1,800 by 12 to get 150 for each interior angle (btw this is only possible since this is a regular polygon meaning that every one of the angles are the same )
Can you help me please (x-2)(x-3)=0
=====================================================
Explanation:
Use the zero product property. This is the idea where if A*B = 0, then either A = 0 or B = 0.
This works because 0 times any number is always 0.
In this case A = x-2 and B = x-3
So,
(x-2)(x-3) = 0
x-2 = 0 or x-3 = 0
x = 2 or x = 3
------------------
If we plugged x = 2 back into the original equation, we get
(x-2)(x-3) = 0
(2-2)(2-3) = 0
(0)(-1) = 0
0 = 0
Which confirms x = 2
Let's do the same for x = 3
(x-2)(x-3) = 0
(3-2)(3-3) = 0
(1)(0) = 0
0 = 0
So x = 3 is confirmed as well.
what is the measure of angle MBT
Answer : The measure of angle MBT is 28°.
Step-by-step explanation :
As we see that the ∠NBM is equal to ∠MBT.
That means,
∠NBM = ∠MBT
Given:
∠NBM = (17x - 6)°
∠MBT = (5x + 18)°
According to question:
∠NBM = ∠MBT
(17x - 6)° = (5x + 18)°
17x - 5x = 18° + 6°
12x = 24°
x = 2°
So,
∠NBM = (17x - 6)° = [(17 × 2) - 6]° = 28°
∠MBT = (5x + 18)° = [(5 × 2) + 18]° = 28°
Hence, the measure of angle MBT is 28°.
Answer:
the answer is 28

I just need 8 and 9 pls help been stuck here forever
Answer:
8: C
9: D
10: C
11: D
Step-by-step explanation:
On number 8, the pattern is by starting from 3, and squaring it. Then you take that square and square it again. So 3 squared is 9, and then you square 9 which is 9 times 9 giving you 81. Then you square 81 giving you 6561.
9: Negative exponents work by flipping the number upside down, and then doing normal exponential work on the now denominator.
If the number is 5 to the power of -3, you are flipping 5 to 1/5 and then doing 5 to the power of 3 which is 5x5x5 giving you 125. Therefore the answer would be 1/125.
10 is the same thing as number 9 except backwards, so you flip 1/2^3 to 2^-3
11 is similar, except you have 3.471 times 1/10000
So you add 4 zeros in front of the 3.471 turning it into 0.0003471
