Answers
Answer:
Yes
Step-by-step explanation:
So we substitute the point given x=-5 and y = -3 to see if this solves both equations at the same time so
3(-5) - 9(-3) = 12 -> -15+27 = 12 -> 12 = 12 [this one works]
8(-5) - 14 (-3) = 2 -> -40 + 42 = 2 -> 2=2 [this one works also]
Since (-5,-3) is a solution to both equations, then this is a solution to this system
Answer: Yes
Step-by-step explanation:
Here
x = -5
y = -3
3x - 9y = 12
Here if you substitute x and y,
3 * (-5) - 9 * (-3)
(-15) - (-27)
=12
8x - 14y = 2
8 * (-5) - 14 * (-3)
(-40) - (-42)
= 2

A circular plate has a circumference of 119.32cm. Calculate the diameter.
Answers
Answer:
Diameter is equal to 38 cm.
Step-by-step explanation:
We know that the circumference equals πd (where d is the diameter).
If we round the value of π to 3.14 then we will get...
πd = 119.32
(3.14)d = 119.32
d = 119.32 / 3.14
d = 38 cm
Therefore the diameter is equal to 38 cm
convert 3300 cg to mg scientific notation and decimal notation
Answers
Answer:
[tex]3300cg = 330mg[/tex] --- decimal
[tex]3300cg = 3.3 * 10^2mg[/tex] --- scientific
Step-by-step explanation:
Given
3300 cg
Required
Convert to mg
cg to mg is gotten my multiplying cg by 100
So:
[tex]3300cg = 3300 * 0.1mg[/tex]
[tex]3300cg = 330mg[/tex] ---- decimal notation
Express 330 as 3.30 * 100
[tex]3300cg = 3.3 * 100mg[/tex]
Express 100 at 10^2
[tex]3300cg = 3.3 * 10^2mg[/tex]

C. After 2 yearsthe value will be $605.
D. The rate of change of the value will decrease over time
E.The value will increase by $50 in the first year
Answers
Answer:
C and E
.................
The true statements are (C) After [tex]2[/tex] years the value will be $[tex]605[/tex] and (E) The value will increase by $[tex]50[/tex] in the first year.
Compound Interest:Compound interest (or compounding interest) is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods.
In the first year, the value[tex]=[/tex] $[tex]500+500\times \frac{10}{100}[/tex]
[tex]=500\left ( 1+\frac{10}{100} \right ) \\ =\left ( 500\times 1.1 \right )[/tex]
[tex]=[/tex]$[tex]550[/tex]
Change in price=$[tex]50[/tex]
After 2 years, the price is=$[tex]550+[/tex]$[tex]550 \times\frac{10}{100}[/tex]
=$[tex]550\times(1+\frac{10}{100} )[/tex]
=$[tex]550\times(1.1)[/tex]
=$[tex]605[/tex]
After 3 years, the price=$[tex]605+605\times\frac{10}{100}[/tex]
[tex]=605(1+\frac{10}{100} )[/tex]
[tex]=(605\times1.1)[/tex]
[tex]=[/tex]$[tex]665.5[/tex]
Rate of change[tex]=\frac{(665.5-500)}{500} \times100[/tex]%
[tex]=\frac{165.5}{5}[/tex]%
[tex]=33.1[/tex]%
[tex]\neq 30%[/tex]%
According to the problem, an exponential pt model provides the best fit.
Therefore, the true statements are an option C and E.

Subtract 3
-5y is less than and equal to -3x+25
Then divide by -5
Flip since we divide
Y more than and equal to 3/5x-5

1. A bag of 12 oranges costs $2.99. What is the cost per orange?
2. 4 slices of pizza cost $10.50. At this rate, what is the cost of 10 slices of pizza?
3. 4 pieces of candy cost $0.99. At this rate, what is the cost of 7 pieces of candy?
Answers
Answer:
1- $ 0.25.
2- $ 26.25.
3- $ 1.73.
Step-by-step explanation:
1- Given that a bag of 12 oranges costs $ 2.99, to determine what is the cost per orange, the following calculation must be performed:
2.99 / 12 = X
0.249 = X
Thus, the cost of each orange is $ 0.25.
2- Given that 4 slices of pizza cost $ 10.50, to determine what is the cost of 10 slices of pizza at this rate, the following calculation must be performed:
10.5 / 4 x 10 = X
2.625 x 10 = X
26.25 = X
Thus, the cost of 10 slices of pizza is $ 26.25.
3- Given that 4 pieces of candy cost $ 0.99, to determine what is the cost of 7 pieces of candy at this rate, the following calculation must be performed:
0.99 / 4 x 7 = X
0.2475 x 7 = X
1.7325 = X
Thus, the cost of 7 pieces of candy is $ 1.73.

this is a math question find the complement of 50 degree
Answers
Given:
The measure of an angle is 50 degrees.
To find:
The complement of the given angle.
Solution:
We know that the sum of an angle and its complement is 90 degrees.
Let x be the complement angle of 50 degrees.
[tex]x+50^\circ=90^\circ[/tex]
[tex]x=90^\circ-50^\circ[/tex]
[tex]x=40^\circ[/tex]
Therefore, the measure of complement of the given angle is 40 degrees.
