Write the equation for the following graph:
Slope (m)
Y-intercept (b)=
Equation: y =
X +
Answer:
y = - 3x - 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 4) and (x₂, y₂ ) = (0, - 2) ← 2 points on the line
m = [tex]\frac{-2-4}{0+2}[/tex] = [tex]\frac{-6}{2}[/tex] = - 3
The line crosses the y- axis at (0, - 2 ) ⇒ b = - 2
y = - 3x - 2 ← equation of line

David wants to buy a bowling ball that has a price of $120. As a member of a bowling league, he is entitled to a 15% discount off the price of the bowling ball. He will also have to pay 6% sales tax on the discounted price of the bowling ball. What is the final price David pays for the bowling ball, after the sales tax and discount applied?
Answer:
$109.2
Step-by-step explanation:
Given data
Cost of bowling ball= $120
DIscount= 15%
Tax= 6%
let us calculate the discount and tax
=15/100*120
=0.15*120
=$18
=6/100*120
=0.06*120
=$7.2
In all the bill is 120-18+7.2
=102+7.2
=$109.2

Divide both sides by 4
[tex]\frac{4x}{4} = \frac{24}{4}[/tex]
[tex]x = \frac{24}{4}[/tex]
[tex]x = 6[/tex]

In the parallelogram below,
x = [? ]°
Z
339
1249
Answer:
23
Step-by-step explanation:
Angle x and the two given angles form a triangle. The interior angles of a triangle add up to be 180.
so
[tex]124 + 33 + x = 180[/tex]
[tex]157 + x = 180[/tex]
[tex]x = 23[/tex]
In the parallelogram below, the value of x is [tex]23^o[/tex] using the angle sum property .
The angle sum property states that:
The sum of all the interior angles of a triangle is [tex]180^o[/tex].
A parallelogram is a four sided figure in which opposite sides are equal and parallel.
Given that:
A parallelogram in which the measurement [tex]124^o[/tex] and [tex]33^o[/tex] is given.
The parallelogram is divided into two triangles.
The value of x can be calculated as:
[tex]x+ 33^o + 124^o = 180^o[/tex] (Angle sum property)
[tex]157^o +x = 180^o[/tex]
x =[tex]180^o- 157^o[/tex]
x = [tex]23^o[/tex]
Thus, the value of x is [tex]23^o[/tex].

A small submarine starts at –1,260 feet in relation to sea level. Then it descends 5 feet per minute for 12 minutes.
What expression represents the new position of the submarine in relation to sea level?
Answer:
We know it's at -1260 feet and descends 5 per minute
The expression of this would be: -1260 - 5x, where x would be the time in minutes, as from -1260 feets it descends 5 per min.
Then, if we need to calculate it when it passes 12 minutes, we can replace the x by 12, and get the distance it would be
-1260 -5*12 = -1320 feet
And the answer would be -1320 feets
pls this is a simultaneous equation- one linear one quadratic a-2b =2 -------- (1). a²+b²+2a -3b =19 --------(2). pls I need it urgently thanks
Answer:
Hence a = 3.66 and -3.628
b = 0.834 and -2.634
Step-by-step explanation:
Given the equations
a-2b =2 -------- (1)
a²+b²+2a -3b =19 --------(2).
From 1;
a = 2 + 2b
Substitute into 2
(2+2b)²+b²+2a -3b =19
Expand
4 + 8b + 4b²+b²+2(2+2b)-3b = 19
4b²+b²+8b+4b+4+4-3b = 19
5b²+9b+8 = 19
5b²+9b-11 = 0
b = -9±√81+4(55)/2(5)
b= -9±√301/10
b = -9+17.34/10 and -9-17.34/10
b = 8.34/10 and -26.34/10
b = 0.834 and -2.634
Since a = 2+2b
a = 2+2(0.834)
a= 2 +1.668
a = 3.668
Also
a = 2+2(-2.634)
a = 2 - 5.628
a = -3.628
Hence a = 3.66 and -3.628
b = 0.834 and -2.634

HALF of the rooms are filled. How
many rooms are still available?
Answer:
225
Step-by-step explanation:
450 ÷ 2 = 225
Answer:
225 rooms

Find 1/2 or 50% of 450. 50% of 450 is 225. So 225 rooms are full, and 225 are empty.
Line CD contains points A (4, 6) and B (4, 3). The slope of line CD is (2 points)
positive
undefined
negative
zero
Answer:
slope is undefined
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = A(4, 6) and (x₂, y₂ ) = B(4, 3)
m = [tex]\frac{3-6}{4-4}[/tex] = [tex]\frac{-3}{0}[/tex]
Division by zero is undefined thus the slope of CD is undefined

A certain brand of shampoo contains 12 ounces in a bottle. The company
decides to redesign the shape of the shampoo bottle. The new type of
bottle contains 15 ounces of shampoo. What is the percent of increase in
the amount of shampoo the new bottle contains?
Answer: 15% I think
Step-by-step explanation:
The percent of increase in the amount of shampoo the new bottle contains is 25%.
Given that, a certain brand of shampoo contains 12 ounces in a bottle and the new type of bottle contains 15 ounces of shampoo.
What is the percentage of increase?Percentage increase is the difference between the final value and the initial value, expressed in the form of a percentage.
Percentage increase = (Final value - Initial value) / Initial value × 100
Now, initial value = 12 and final value = 15
Percentage increase = (15-12)/12 × 100
= 3/12 × 100
= 1/4 × 100
=25%
Therefore, the percent of increase in the amount of shampoo the new bottle contains is 25%.
