7^7/7^3 = 7^x
Answer: x = 4
Step-by-step explanation:
First, we must divide the two, its in a fraction, and as you should know, when we divide exponents, you subtract the exponent on the numerator by the exponent on the denominator. So in this case we are doing 7 - 3 which is equal to 5.
[tex]7^5 = 7^x[/tex]
[tex]7^5 = 7^5[/tex]
Then we still need to subtract [tex]7^1[/tex] from [tex]7^5[/tex].

Triangle a'b'c' is result of dilating abc about point a by a scale factor of 2/3. Determine whether each claim about the properties of abc and a'b'c' is true or false
Answer:
True , because all properties preserved under dilation from triangle abc to a'b'c'.
Step-by-step explanation:
Given : A triangle abc is dilated by a factor of 2/3 , result triangle a'b'c'
To find :After dilation, properties of triangle abc and a'b'c' is true or false.
Solution:
Dilation of a triangle are result either decrease or increase the corresponding length of triangle , its depends on by which scale factor triangle is dilated ,and dilation does not affect the angle measures of triangle.here scale factor is 2/3 so corresponding sides of triangle a'b'c' decreases.
So, dilation of triangle are not congruent but similar to the original triangle abc
Therefore , basic properties of triangle preserved under dilation of triangle by a scale factor.

Write the coordinates of the vertices after a dilation with a scale factor of 1/5, centered at the origin.
Answer:
The coordinates of the vertices after the dilation by a scale factor 1/5 centered at the origin will be:
U'(-1, -2)V'(0, -2)W'(-1, 2)Step-by-step explanation:
We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.
If the scale factor > 1, the image is enlarged
If the scale factor is between 0 and 1, it gets shrunk
If the scale factor = 1, the object and the image are congruent
Rule to calculate the dilation by a scale factor 1/5 centered at the origin
P(x, y) → P'(1/5x, 1/5y)
Here, P'(1/5, 1/5y) is the image of P(x, y).
Given the vertices of the triangle UVW
U (-5, -10)
V (0, -10)
W (-5, 10)
so
Rule to calculate the dilation by a scale factor 1/5 centered at the origin
P(x, y) → P'(1/5x, 1/5y)
U (-5, -10) → U'(1/5(-5), 1/5(-10)) → U'(-1, -2)
V (0, -10) → V'(1/5(0), 1/5(-10)) → V'(0, -2)
W (-5, 10) → W'(1/5(-5), 1/5(10)) → W'(-1, 2)
Therefore, the coordinates of the vertices after the dilation by a scale factor 1/5 centered at the origin will be:

Step-by-step explanation:

y - 5 = - 3(x + 1)
y = - 3x + 2
Write the equation of the line in slope intercept form that passes through the point (-3, 5) and is parallel to y= - 2/3x
Answer:
The equation of the line in slope intercept form that passes through the point (-3, 5) and is parallel to y= - 2/3x is [tex]\mathbf{y=-\frac{2}{3}x+3 }[/tex]
Step-by-step explanation:
We need to Write the equation of the line in slope intercept form that passes through the point (-3, 5) and is parallel to y= - 2/3x
The equation in slope-intercept form is: [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
Finding Slope:
The both equations given are parallel. So, they have same slope.
Slope of given equation y= - 2/3x is m = -2/3
This equation is in slope-intercept form, comparing with general equation [tex]y=mx+b[/tex] where m is slope , we get the value of m= -2/3
So, slope of required line is: m = -2/3
Finding y-intercept
Using slope m = -2/3 and point (-3,5) we can find y-intercept
[tex]y=mx+b\\5=-\frac{2}{3}(-3)+b\\5=2+b\\ b=5-2\\b=3[/tex]
So, we get b = 3
Now, the equation of required line:
having slope m = -2/3 and y-intercept b =3
[tex]y=mx+b\\y=-\frac{2}{3}x+3[/tex]
The equation of the line in slope intercept form that passes through the point (-3, 5) and is parallel to y= - 2/3x is [tex]\mathbf{y=-\frac{2}{3}x+3 }[/tex]
Answer:
[tex]\displaystyle y = -\frac{2}{3}x + 3[/tex]
Step-by-step explanation:
5 = –⅔[–3] + b
2
[tex]\displaystyle 3 = b \\ \\ y = -\frac{2}{3}x + 3[/tex]
Parallel equations have SIMILAR RATE OF CHANGES [SLOPES], so –⅔ remains as is.

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the first number be = A
Let the second number be = B
Now , the value of A = 4.12
And , the value of B = 4.21
Now , we can clearly see the value of B is greater than A
So , the equation will be
Therefore , the value of B > A
And , 4.21 > 4.12

Answer:
Sabrina bought 3 pounds of bananas.
Step-by-step explanation:
Given equations are:
a + b = 8 Eqn 1
0.95a + 1.10b = 8.05 Eqn 2
As we have to find the number of pounds of bananas bought, we will eliminate the variable a from the equation.
Multiplying Eqn 1 by 0.95
0.95(a+b=8)
0.95a+0.95b=7.60 Eqn 3
Subtracting Eqn 3 from Eqn 2
(0.95a+1.10b)-(0.95a+0.95b)=8.05-7.60
0.95a+1.10b-0.95a-0.95b=0.45
0.15b = 0.45
Dividing both sides by 0.15
[tex]\frac{0.15b}{0.15}=\frac{0.45}{0.15}\\b = 3[/tex]
Hence,
Sabrina bought 3 pounds of bananas.

A company that offers tubing trips down a river rents tubes for a person to use and "cooler" tubes to carry food and water. A group spends $270 to rent a total of 15 tubes. Write a system of linear equations that represents this situation. Use $x$ to represent the number of one-person tubes rented and $y$ to represent the number of cooler tubes rented. How many of each type of tube does the group rent?
Answer:
the group rents is 11 person tubes and there is 4 cooler tubes
Step-by-step explanation:
The computation is shown below:
The equation are as follows:
x + y = 15
y = 15 - x
And, the cost of person tube is $20
The cost of the cooler tube is $12.50
The total spending is $270
Now the equation is
20x + 12.50y = 270
Now put the value of y in the above equation
20x + 12.50(15 - x) = 270
20x + 187.50 - 12.50x = 270
20x - 12.50x + 187.50 = 270
7.50x + 187.50 = 270
7.50x = 270 - 187.50
7.50x = 82.50
x= 11
Now put the value of y in any of the equation
y = 15 - 11
= 4
So, the group rents is 11 person tubes and there is 4 cooler tubes

Answer:
y = 4x - 9
Step-by-step explanation:
Take 2 points:
(0,-9) and (4,7)
Find the slope:
(7 - (-9))/(4 - 0)
16/4 = 4
so we have y = 4x + b
Now find b:
Insert a point for y and x:
7 = 4(4) + b
7 = 16 + b
b = -9
y = 4x - 9

(5 pts) A quadratic function f is given by f(x) = ax2 + bx + c where a is not 0. Select all
the statements that must be true about the graph of f.
a.
The y-intercept of the graph is at (0,c).
b.
The graph has an x-intercept at (c,0).
C.
When a < 0 the graph is open downward.
d.
The graph has two x-intercepts.
e.
If b = 0, then the vertex is on the y-axis.
Answers:
a) True. Plug in x = 0 and it leads to y = c. Therefore, the point (0,c) is on the parabola.b) False. Plug in y = 0 and apply the quadratic formula. One x intercept may sometimes be x = c, but it could easily be other values as well. Or perhaps you may not get any real number solutions at all. See part d) below.c) True. If a < 0, then the leading coefficient is negative. Overall, both endpoints will tend toward negative infinity to produce a parabola that opens downward.d) False. The quadratic may have one x intercept or it may not have any x intercepts at all. It depends on what the discriminant d = b^2 - 4ac is equal to. If d < 0, then we have no x intercepts. If d = 0, then we have exactly 1 x intercept. If d > 0, then we have two different x intercepts.e) True. The vertex's x coordinate is -b/(2a). If b = 0, then the x coordinate of the vertex is 0. The vertical line x = 0 is directly on top of the y axis.If the value of a is less than zero then the parabola is open downward. Then the correct option is C.
What is a quadratic equation?It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.
