Answer:
-4.
Step-by-step explanation:
5(m - 1) = -25
m - 1 = -5
m = -4.
Answer:
m = -4
Step-by-step explanation:
Divide both sides by the numeric factor on the left side, then solve.
m = -4
What is the range of the function for the given domain?
y = 2x - 5
D: (-2,0, 2,4}
Select the correct answer.
OR: {-9, 0,-1,3}
OR: {9,-5, 9, 13}
OR: {-9, -5, -1,3}
OR: {-9, 0, 9, 13}
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{ - 9 \: , \: - 5 \: , - 1 \: , \: 3 \: }}}}}[/tex]
Option C is the correct option.
Step-by-step explanation:
Here, y = 2x - 5 and domain ( D ) = { -2 , 0 , 2 , 4 )
when, x = -2 , Range = 2 × (- 2)- 5 = - 4 - 5 = -9
when, x = 0 , range = 2 × 0 - 5 = 0 - 5 = -5
when x = 2 , range = 2 × 2 - 5 = 4 - 5 = -1
when, x = 4 , range = 2 × 4 - 5 = 8 - 5 = 3
Range = { -9 , -5 , -1 , 3 }

The length of each edge of a cube is x centimeters. If x is an integer, why can't the volume of the cube equal 15cm. Show work please
Let's try some integer values of x to see what volumes we get
If x = 0, then x^3 = 0^3 = 0*0*0 = 0If x = 1, then x^3 = 1^3 = 1*1*1 = 1If x = 2, then x^3 = 2^3 = 2*2*2 = 8If x = 3, then x^3 = 3^3 = 3*3*3 = 27We do not get 15 as a result in that list above. So there are no integer solutions to x^3 = 15
In other words, the value [tex]\sqrt[3]{15}[/tex] is not an integer.
Find the area of the polygon with the given vertices. N(-2,1), P(3,1), Q(3, -1), R(-2, -1)
Answer:
10
Step-by-step explanation:
N(-2,1), P(3,1), Q(3, -1), R(-2, -1)
The polygon is the rectangle with sides 2 and 5
So the area is 2*5 = 10

Beth enlarged the triangle below by a scale of 5. She found the area of the enlarged triangle. Her work is shown below.
What was Beth’s error?
She should have divided One-half (4) (3.5) by 5.
She should have divided One-half (4) (3.5) by 5 squared.
She should have multiplied (4) (3.5) by 5.
She should have multiplied One-half (4) (3.5) by 5 squared.
Answer:
The possible error made by Beth is directly multiplying scale of 5 to area of original triangle and getting area of enlarged triangle, which is wrong.
Step-by-step explanation:
Originally Triangle has height =3.5cm and width=4cm
Beth enlarged the same triangle by scale of 5 and calculate area of triangle
The area of triangle as given as A= $$\frac{1}{2} \texrm{ (base) (height)}$$
Area of original triangle is A =$$\frac{1}{2}(3.5 \times 4)$$
Since, The triangle is enlarged by scale of 5
New height =3.5x5 = cm and new width=4x5cm
Area of new triangle is
A' = $$\frac{1}{2} (\textrm{new width} ) ( \textrm{new height})$$
A' = $$\frac{1}{2}(3.5 \times 5)(4\times 5)$$
A' = $$\frac{1}{2}(3.5 \times 4)(5^{2})$$
A' = $$A (5^{2})$$
Now, Looking what error beth made is:
Beth found Area of new triangle is A' = $$\frac{1}{2}(3.5)(4)(5)$$
The possible error made by Beth is directly multiplying scale of 5 to area of original triangle and getting area of enlarged triangle, which is wrong.

5^(9 - 3x) = 1255^(9 - 3x) = 5^39 - 3x = 33x = 9 - 33x = 6x = 6/3x = 2find the distance between each pair of points (-6,-5) (2,0)
Answer: The distance is about 9.43
Step-by-step explanation:
To find the distance between these numbers find the difference in the x and y values then square them and add them together and finally find the square root of the number you got after adding them.
-5 - 0 = -5
-6 - 2 = -8
-5^2 + -8^2 = d^2 where d is the distance
25 + 64 = d^2
89 = d^2
d = [tex]\sqrt{89}[/tex]
d= 9.43

Utilize PEMDAS to solve the problems.
[tex]\frac{-44.288-31.6}{-3.1(6-1.2)}[/tex]
[tex]\frac{-75.888}{-3.1(4.8)}[/tex]
[tex]\frac{-75.888}{-14.88}[/tex]
[tex]5.1[/tex]
Hope this helps.
頑張って!
Answer:
5.1
Step-by-step explanation:
first you subtract -44.288 - 31.6= -75.888
then subtract 6-1.2= 4.8
then multiply -3.1x4.8= -14.88
then divide -75.888/-14.88= 5.1

Given the points R(-4, 5) and S(2, -1). Find RS, the midpoint of RS, and point P which is 13 of the distance from R to S. Leave your answer as a simplified radical.
Answer:
Step-by-step explanation:
Given the points R(-4, 5) and S(2, -1), to get the distance between the points, we will use the formula;
D = √(x2-x1)²+(y2-y1)²
Given x1= -4, y1 = 5, x2 = 2 and y2 = -1
RS = √(2-(-4))²+(-1-5)²
RS = √(6)²+(-6)²
RS = √36+36
RS = √72
RS = √2×36
RS = 6√2units
To get the midpoint, we will use the formula M(X,Y) = (x1+x2/2, y1+y2/2)
(X,Y) = (-4+2/2, -1+5/2)
(X,Y) = (-2/2, 4/2)
(X,Y) = (-1,2)
Hence the midpoint is (-1,2)
To get a point P 1/3 of the distance of RS, we will multiply 1/3 with the the distance RS as shown
P = 1/3 × 6√2
P = 2√2
Solve for x. 4x+7y+5xy=0
Answer:
x = -7y/(4 +5y)
Step-by-step explanation:
You can treat y as though it were a constant. As in any 2-step linear equation, you separate the variable term(s) from the constant term, then divide by the coefficient of the variable.
4x +5xy = -7y . . . . . subtract 7y
x(4 +5y) = -7y . . . . . factor out x, so we can see its coefficient
x = -7y/(4 +5y) . . . . divide by the coefficient of x

10v-3v=35 what is the answer to this.
answer is v=5
Step-by-step explanation:
10v-3v=7v
7v=35
v=35/7
v=5
Answer: [tex]v=5[/tex]
Simplify both sides of the equation
[tex]10v+-3v=35[/tex]
[tex](10v+-3v)=35[/tex] (Combine Like Terms)
[tex]7v=35[/tex]
Divide both sides by 7
