Answer:
She needs to run down 4.5 flights of stairs to represent an additive inverse
Step-by-step explanation:
Having an additive inverse means that she will be back at point zero.
The point zero in this context simply refer to her starting point.
So if she has run up 4.5 flights of stairs, then to be back at her starting point, she needs to run down also 4.5 flights of stairs

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

–6x2 - 235 = -48x + 11
Answer:
6(x-5)2+288
Step-by-step explanation:
6x2-60x+438 Factor out a 6 from the first 2 terms.
6(x2-10x )+438 Do (b/2)2 to find the c term. (-10/2)2 = 25
6(x2-10x+25)+438-150 Adding 25 inside the parenthesis is really like adding 6(25)=150 to that side of the equation. To keep the equation in balance, you have to subtract 150 from the other term. Simplify

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 )

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

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].
What is the value of y in the following system?
4x - 10y = -3
12x + 5y = 12
Y=3/5
First, set it up so they cancel. I recommend multiplying the second equation by 2, getting
[tex]4x-10y=-3[/tex]
[tex]24x+10y=24[/tex]
add them together, and you get
[tex]28x=21[/tex]
so
[tex]x=3/4[/tex]
then, you plug x into one of the equations (first because it's easier) and get
[tex]3-10y=-3[/tex]
so
[tex]-10y=-6[/tex]
and
[tex]y=3/5[/tex]

first you’ll want to do 4/7 times 21 (a number or fraction in front of a parenthesis without a “+” or ”-“ sign must be multiplied) which is 12, then you add 12+5 to get 17. Next you subtract 17 from 41 to get 24, then you will divide 24 by 3x to get 8 = x.

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

sean said that the slope of the line is 3. is he correct?
Answer:
yes
Step-by-step explanation:
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!!!

Answer:
6x + 14
Step-by-step explanation:
Original Equation:
