Step-by-step explanation:
[tex] {3}^{q - 7} = {27}^{q - 7} [/tex]
[tex] {3}^{q - 7} = {3}^{3(q - 7)} [/tex]
[tex]q - 7 = 3(q - 7)[/tex]
[tex]q - 7 = 3q - 21[/tex]
[tex]q - 3q = - 21 + 7[/tex]
[tex] - 2q = - 14[/tex]
[tex]q = \frac{ - 14}{ - 2} [/tex]
[tex]q = 7[/tex]
Answer:
16
Step-by-step explanation:
3(q - 7) = 27
3q - 21 = 27
3q = 27 + 21
3q = 48
q = 48/3
q = 16

Find the slope between:
(4,5)
(3,5)
Answer:
If a line goes through both points, the slope of that line would be [tex]0[/tex].
Step-by-step explanation:
The slope of a line is equal to the ratio between the vertical change of this line "rise" and the corresponding horizontal change "run":
[tex]\begin{aligned}\text{slope} &= \frac{\text{rise}}{\text{run}}\end{aligned}[/tex].
If a non-vertical line goes through two distinct points [tex](x_{0},\, y_{0})[/tex] and [tex](x_{1},\, y_{1})[/tex] where [tex]x_{0} \ne x_{1}[/tex], the vertical change (rise) would be [tex](y_{1} - y_{0})[/tex]. The corresponding horizontal change would be [tex](x_{1} - x_{0})[/tex]. Thus, the slope of that line would be:
[tex]\begin{aligned}\text{slope} &= \frac{\text{rise}}{\text{run}} \\ &= \frac{y_{1} - y_{0}}{x_{1} - x_{0}}\end{aligned}[/tex].
In this question, [tex]x_{0} = 4[/tex] and [tex]y_{0} = 5[/tex] for the first point, whereas [tex]x_{1} = 3[/tex] and [tex]y_{1} = 5[/tex] for the second point.
The rise (vertical change) of this line from the first point to the second would be [tex](y_{1} - y_{0}) = 5 - 5 = 0[/tex]. The corresponding run (horizontal change) would be [tex](x_{1} - x_{0}) = 3 - 4 = -1[/tex].
Thus, the slope of this line would be:
[tex]\begin{aligned}\text{slope} &= \frac{\text{rise}}{\text{run}} \\ &= \frac{y_{1} - y_{0}}{x_{1} - x_{0}} \\ &= \frac{5 - 5}{3 - 4} \\&= \frac{0}{-1} \\ &= 0\end{aligned}[/tex].
In other words, the slope of this line is [tex]0[/tex]. Geometrically, a slope with a slope of [tex]0\![/tex] would be horizontal. The vertical coordinate of all points on such line would be the same ([tex]5[/tex] for points on the line in this question.)
Rashid solves the following system of equations using the elimination method.
6x−5y=−31
5x+3y=10
What value does he correctly determine for x?
Enter you answer in the box. x =
Answer:
X = -1 & and for some additional information Y = -5
Step-by-step explanation:
6 x (-1) = (-6)
5 x (-5) = (-25)
(-6) - (-25) = (-31)
_____________
5 x (-1) = (-5)
3 x (-5) = (-15)
(-5) + (-15) = 10
Answer:
x = -1
Step-by-step explanation:
Rashid may have used elimination to solve the problem, but we can use any method we like to find the correct value of x. One method we like is graphing. The attached graph shows the solution is (x, y) = (-1, 5), so we know Rashid found ...
x = -1
__
If we go down Rashid's path, we multiply the first equation by 3 and add that to the second equation multiplied by 5. (This choice of multipliers results in a positive coefficient for x.)
3(6x -5y) +5(5x +3y) = 3(-31) +5(10)
18x -15y +25x +15y = -93 +50 . . . . . . eliminate parentheses
43x = -43 . . . . . . . . . . . . . . . . . simplify

Base Salary: $48,000
Applications: 910
Fee: $1.75 per application
what’s the total earning
Answer:
$49,592.50
Step-by-step explanation:
First, to find the total fee of application you times 910 by $1.75 which will give you
910 × 1.75 = 1592.5
Then you add 48,000 with 1,592.5
which will give you an answer of
48,000 + 1,592.5 = $49,592.50

how do i solve this
Step-by-step explanation:
multiple ways are possible.
but the easiest might be equation arithmetic, because the y terms are so nicely related.
we multiply the second equation (the whole equation) by 3, and then we add both equations fully :
4x - 6y = 13
-15x + 6y = 15
---------------------
-11x + 0 = 28
-11x = 28
x = -28/11
and that we use in any of the two original equations to get y :
-5x + 2y = 5
-5(-28/11) + 2y = 5
140/11 + 2y = 5 = 55/11
2y = -85/11
y = -85/11 / 2/1 = -85/22
let's make the check :
4×-28/11 - 6×-85/22 = 13
-112/11 + 510/22 = 13
-112/11 + 255/11 = 13
143/11 = 13
13 = 13
correct.

Include explanation!!
Answer:
Angle ABE = 58
Step-by-step explanation:
This would fulfill the AAA theorem, or 3 angles needing to be congruent. We got 58 by subtracting 89 and 62 from 180, then multiplying that answer by 2 (because it occupies both triangles).

In plane ABC the measure of angle A equals 42° the measure of angle B is five times the measure of angle C find the measure of angle B and the measure of angle C.
Step-by-step explanation:
I think what is meant in the triangle ABC we have the three angles.
the sum of all angles in a triangle is airways 180 degrees.
so,
180 = A + B + C
180 = 42 + B + C
now, we know also that
B = 5×C
so, we can use that above
180 = 42 + 5×C + C
138 = 6×C
C = 138/6 = 23 degrees
B = 5×C = 5×23 = 115 degrees

Find the surface area of a cube
with side length 8.5 cm.
=========================================================
Explanation:
A cube has 6 identical faces, all of which are squares.
Each square has a side length of 8.5 cm, so its area is (8.5)^2 = 72.25 sq cm.
The overall surface area, aka the area of all 6 faces combined, is 6*72.25 = 433.5 square cm
Answer:
A=433.5cm²
Step-by-step explanation:
A=6a2=6·8.52=433.5cm²

the midpoint of (3 x, -2) and (-4, 5y) is (1,4). find x, -y
Answer:
(x,-y): (2,-2)
Step-by-step explanation:
M=(x+x)/2,(y+y)/2
Given (1,4)=
[tex] \frac{3x - 4}{2} [/tex]
This implies:
[tex]1 = \frac{3x - 4}{2} [/tex]
[tex]3x - 4 = 2 \\ 3x = 2 + 4 \\ \frac{3x }{3} = \frac{6}{3} \\ x = 2[/tex]
In a similar way,
[tex]4 = \frac{ - 2 + 5y}{2} \\ - 2 + 5y = 8 \\ 5y = 10 \\ y = 2[/tex]
The question demanded (x,-y)
Hence(2,-2) is the answer

S2x+3y=-12
(4x-4y=4
Answer:
I'll assume "S2x+3y=-12" is actually 2x+3y=-12 and that the question is to solve for x and y.
x = -(9/5)
y = -(14/5)
Step-by-step explanation:
2x+3y=-12
4x-4y=4
---
2x+3y=-12
8x+12y=-48 [Multiply the 1st equation by 4]
12x-12y=12 [Multiply the second equation by 3]
20x = -36 [Now we can add the two equations to remoce the y term]
x = -(36/20)
x = -(9/5) [The value for x]
====
2x+3y=-12 [Take either equation and s=use x=-(9/5) to find y]
2(-9/5)+3y=-12
-(18/5) + 3y = -12
+ 3y = -12 + (18/5)
y = -4 + (6/5)
y = -(20/5)+(6/5)
y = -(14/5) [This is the value of y that will work for both equations]
These equations both have the point (-9/5, -14/5) in common: they intersect here.
This problem can also be solved by graphing each equation and finding the point they inersect on the graph (attached).
