Clare failed to flip the inequality when dividing by a negative number
Step-by-step explanation:
-4x+3 < 23
Subtract 3 from each side
-4x+3-3 < 23-3
-4x < 20
Divide each side by -4, remembering to flip the inequality

PLEASE HELP I WILL GIVE BRIANLIEST 15 POINTS!!! What is the equation in slope-intercept form of the line that crosses the x-axis at 36 and is perpendicular to the line represented by y = -4/9x+5
Answer
A y = 4/9x+16
B y = 4/9x-16
C y= 9/4x+81
D y = 9/4x-81
Answers
Answer:
Choice D
Step-by-step explanation:
First we should find the slope of the equation, so since it's perpendicular to the other equation that means it's the opposite and the reciprocal of that slope. So the slope is [tex]\frac{9}{4}[/tex].
Now we have to find the y-intercept. We already know the x-intercept, so we could use that to find the y-intercept. For that we need to know the slope and one ordered pair, which is (36,0). Then we plug into this formula [tex]y=mx+b[/tex].
[tex]y=mx+b\\0=\frac{9}{4}(36)+b\\0=81+b\\b=-81[/tex]
So now that we found the y-intercept we just have to put it all together....
[tex]y=\frac{9}{4}x-81[/tex]

C is the midpoint of segment AB D is the midpoint of segment BC A is located at (4,8) and B is located at (-12,4) what are the coordinates of D
Answers
Answer:
coordinates of D are ( -8, 5)
Step-by-step explanation:
- the formula of the coordinates of the midpoint is (x1+x2)/2 & (y1+y2)/2
- first we find midpoint C by using coordinates of points A and B
C => (4 - 12)/2 & (8 + 4)/2
calculate, coordinates of C are ( -4, 6 )
- now find midpoint D by using the coordinates of B and C
D => ( -12 - 4 )/2 & (4 +6)/2
calculate and the coordinates of D are ( -8, 5 )

Write a function for the graph of y=3x+7 after the slope is doubled.
Answers
Answer:
Please check the explanation.
Step-by-step explanation:
Given the function
[tex]y=3x+7[/tex]
As we know that the slope-intercept of the line equation is
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
so comparing the equation [tex]y=3x+7[/tex] with the slope-intercept of the line equation, we conclude that
[tex]y = 3x+7[/tex]
[tex]m = 3[/tex]
So, the slope of the line is [tex]m = 3[/tex]
As the function is
[tex]y = 3x+7[/tex]
Now, if we double the slope,
The slope will become: 2m = 2(3) = 6
Therefore, the function of the graph after doubling the slope will become:
[tex]y = 6x+7[/tex]

parallel lines A B and C D are cut by a transversal forming 8 angles labeled 1 to 8. The transversal intersecting line A B form angles 1, 2, 3, and 4 clockwise from top left. The transversal intersecting line C D form angles 5, 6, 7, 8 clockwise starting from top left.
Answers
Answer:
m∠8 = 30°
Step-by-step explanation:
Since line AB is parallel to line CD, and m∠4 = 30°, therefore:
m∠4 and m∠8 are corresponding angles.corewslinding angles are congruent.
Therefore, this means that their measure would be equal to each other, since they are congruent.
Thus:
m∠8 = 30°

gave her the right advice for how to fix it. What advice did Jennifer give to Ruby?
O
Multiply both sides of the equation by 3. The standard form of the equation is 12x - 2y = 21.
Oь
Jennifer told Ruby her equation is already in standard form and there is nothing to correct.
Oc
Multiply both sides of the equation by 3. The standard form of the equation is 12x - 2y = 7
Multiply both sides of the equation by 3 and then divide both sides by 2. The standard form of the equation is 6x - y = 10.5.

En la sala de una casa hay una gran ventana de vidrio, por la que se presenta una pérdida significativa de calor; las medidas de la ventana son 2,5 m x 1,5 m y 2,8 mm de espesor. Hallar la variación de calor en la unidad de tiempo si la temperatura exterior del vidrio es 16°C y la temperatura interior del vidrio es 20°C
Answers
Answer:
La variación de calor por unidad de tiempo es 4285.714 watts, es decir, joules por segundo.
Step-by-step explanation:
Asumamos que la transferencia de calor es enteramente por conducción, en estado estable y unidimensional´y que la ventana es representada por una placa plana. Bajo estas consideraciones, la ecuación de conducción es la siguiente:
[tex]\dot Q = \frac{k\cdot w\cdot h}{l}\cdot (T_{i}-T_{o})[/tex] (1)
Donde:
[tex]\dot Q[/tex] - Tasa de transferencia de calor, medida en watts.
[tex]k[/tex] - Conductividad térmica, medida en watts por metro-grado Celsius.
[tex]w[/tex] - Ancho de la ventana de vidrio, medido en metros.
[tex]h[/tex] - Altura de la ventana de vidrio, medida en metros.
[tex]l[/tex] - Espesor de la ventana de vidrio, medida en metros.
[tex]T_{i}[/tex] - Temperatura interior del vidrio, medida en grados Celsius.
[tex]T_{o}[/tex] - Temperatura exterior del vidrio, medida en grados Celsius.
Si conocemos que [tex]k = 0.8\,\frac{W}{m\cdot ^{\circ}C}[/tex], [tex]w = 2.5\,m[/tex], [tex]h = 1.5\,m[/tex], [tex]l = 2.8\times 10^{-3}\,m[/tex], [tex]T_{o} = 16\,^{\circ}C[/tex] y [tex]T_{i} = 20\,^{\circ}C[/tex], entonces la tasa de transferencia de calor es:
[tex]\dot Q = \left[\frac{\left(0.8\,\frac{W}{m\cdot ^{\circ}C} \right)\cdot (2.5\,m)\cdot (1.5\,m)}{2.8\times 10^{-3}\,m} \right]\cdot (20\,^{\circ}C-16\,^{\circ}C)[/tex]
[tex]\dot Q = 4285.714\,W[/tex]
La variación de calor por unidad de tiempo es 4285.714 watts, es decir, joules por segundo.
