How many solutions does this equation have? –10 − 9z = –4 − 10z
Answer:
1 solution
Step-by-step explanation:
-10 - 9z = -4 - 10z
Isolate z:
-9z + 10z = -4 + 10
z = 6
This is the only solution, so the equation has 1 solution.
Answer:
z = 6
1 solution
Step-by-step explanation:
–10 − 9z = –4 − 10z
Add 10z to each side
–10 − 9z+10z = –4 − 10z+10z
-10 +z = -4
Add 10 to each side
-10 +z +10 = -4+10
z = 6

1-3x = 1 - x
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{0}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{1 - 3x = 1 - x}[/tex]
Move x to left hand side and change it's sign
Similarly, move 1 to right hand side and change it's sign
[tex] \dashrightarrow{ \sf{ - 3x + x = 1 - 1}}[/tex]
Collect like terms

A damsel is in distress and is being
held captive in a tower. Her knight in
shining armor is on the ground below
with a ladder. When the knight stands
15 feet from the base of the tower and
looks up at his precious damsel, the
angle of elevation to her window is 60
degrees. How long does the ladder
have to be?
Answer:
30 feet
Step-by-step explanation:
Let x be the length of the ladder. Then, x cos(60) = 15
If we divide both sides by cos(60), then x = 30 feet.
The length of ladder to be used by knight will be of 30 feet
What is angle of elevation?The angle of elevation is an angle that is formed between the horizontal line and the line of sight. If the line of sight is upward from the horizontal line, then the angle formed is an angle of elevation.
According to the question
The knight stands 15 feet from the base of the tower and the
angle of elevation to her window is 60 degrees.
Therefore, In figure
AB = Height of tower
CA = Distance between knight and tower = 15 feet
BC = Length of the ladder
angle of elevation = 60°
Now ,
Cos(60°) = [tex]\frac{Base}{Hypotenuse} = \frac{distance between knight and tower}{Length of the ladder } = \frac{15}{BC}[/tex]
[tex]\frac{1}{2} = \frac{15}{BC}[/tex]
BC = 30 feet
Length of the ladder = 30 feet
Hence, the length of ladder will be used is 30 feet .

Dwayne buys 1 loaf of bread and 6 eggs for $4.45. Sheila buys 1 loaf of bread and 1 dozen eggs for $5.65. Let x be the cost, in dollars, of a loaf of bread. Let y be the cost, in dollars, of an egg.
Answer:
cost of bread = $3.25
Cost per egg = $0.2
Step-by-step explanation:
Given the following :
Cost of a loaf of bread and 6 eggs = $4.45 - - (1)
Cost of a loaf of bread and a dozen eggs ( 12 eggs) = $5.65 - - - (2)
Let x = cost of bread and y = cost of egg
x + 6y = 4.45
x + 12y = 5.65
Subtract 1 from 2
6y - 12y = 4.45 - 5.65
-6y = - 1.2
y = $0.2
Hence,
From x + 6y = $4.45
Where y = $0.2
x + 6($0.2) = $4.45
x + $1.2 = $4.45
x = $4.45 - $1.2
x = $3. 25
Hence, cost of bread = $3.25
Cost per egg = $0.2

point r is rotated about the center shown by 270 clockwise which point is the image of r choose one answer
please help
Answer: D
Step-by-step explanation:
1/3) Let’s imagine a circle that passes through point R with the given center.
2/3) A 270 ángel takes up 3 on 4 of the circle.
3/3) D is the image of point R.
Clockwise rotation means rotating in the same way or direction as the hands of a clock move.
If point R is rotated about the center by 270 clockwise the image of point R is point D.
What is clockwise rotation?Clockwise rotation means rotating in the same way or direction as the hands of a clock move.
We have,
Point R is rotated clockwise about the center by 270 degrees.
We need to find the position of the R after the rotation.
i.e the image of the point R.
We know that the whole circle rotation is considered to have a 360-degree rotation.
270-degree rotation means it has rotated 3/4th of the circle.
So from the given figure, if the point R is rotated 3/4th of the figure in a clockwise direction the point R will be in the position of point D.
i.e the image of point R will be Point D.
Thus the image of point R is point D.
