So in this equation we have to solve using PEMDAS, or parentheses, exponents, multiplication, division, addition, then subtraction, going from left to right. So first, i deal with whats in the parentheses, but since it cannot be subtracted, I next go on to the next step. Since there are no exponents, our next step is to multiply or distribute 2 into (-3-6x). In other words, i multiply 2 by -3 and 2 by -6x. This is going to be -6 -12x. After that, i add and subtract common factors, so 3x-12x is -9x, and -4-6 is -10. This leaves us with -9x-10=0. I add 10 to each side according to addition property of equality. Thus, the equation is -9x=-10. Divide both sides by -9, by the division property of equality, and u get 10/9. If you want a decimal answer, type it into a calculator.

For the given right triangle, find the value x to the nearest tenth:
What’s the measurement of
Step-by-step explanation:
4x and 6x sit on a straight line therefore must equal to 180°
4x+6x = 180° (∠'s on str. line)
10x = 180
x= 180/10
x= 18
Then we need to find ∠UYV
∠UYV = 4x
=4(18)
=72°
So ∠UYV = 72°
1. Annual sales for a fast food restaurant are $650,000 and are increasing at a rate of 4% per year
Use an exponential function to find the annual sales after 7 years.
Answer:
The value after 7 years is $ 855355.65
Solution:
Given that, Annual sales for a fast food restaurant are 650000 and are increasing at a rate of 4% per year
To find: exponential function to find the annual sales after 7 years
The exponential growth function is given as:
Where,
"a" is the initial amount
"y" is the future value
"r" is the rate of interest in decimal
"t" is the number of years
Here in this given question,
a = 650000
t = 7 years
Substituting the values in given formula,
Thus the value after 7 years is $ 855355.65

In ARST, r = 52 cm, s = 55 cm and ZT=48°. Find the length of t, to the nearest
centimeter.
9514 1404 393
Answer:
44 cm
Step-by-step explanation:
The law of cosines is applicable.
t^2 = r^2 + s^2 -2rs·cos(T)
t^2 = 52^2 +55^2 -2·52·55·cos(48°) ≈ 1901.57
t ≈ √1901.57 ≈ 43.607
The length of t is about 44 cm.
Hey there!
[tex]\dagger \: \sf\red{Question:}[/tex]In ARST, r = 52cm, s = 55cm and ZT = 48°. Find the length of T, to the nearest centimeter. [tex]\dagger \: \sf\blue{Solution:}[/tex]By the law of cosines,
[tex]{\underline{\boxed{\frak{\pmb{\quad {t}^{2} = {r}^{2} + {s}^{2} - 2rs \times cos(T) }}}}} [/tex][tex]\implies\tt[/tex] t² = (52)² + (55)² - 2 × 52 × 55 × cos(48°)
[tex]\implies\tt[/tex] t² ≈ 1901.57
[tex]\implies\tt[/tex] t² = √1901.57
[tex]\implies\tt[/tex] t² = 43.607

Ulet rolls 2 fair dice and adds the results from each. Work out the probability of getting a total of 7.
Answer:
7/ 36
Step-by-step explanation:
Roll of 2 fair six sided die :
Sample space = 6² = 36
Sum of 7:
(1,6) ; (6,1) ; (3,4) ; (4,3) ; (2,5) ; (5,2) = 6
Probability = required outcome / Total possible outcomes
Required outcome = 7
Total possible outcomes = 36
P(obtaining a sum of 7) = 7 / 36

The real answer is y=5
Step-by-step explanation:
because its horizontal
y=5 represents a line which is perpendicular to the y-axis
What is Straight line?A line is an infinitely long object with no width, depth, or curvature. Thus, lines are one-dimensional objects
We need to find the equation which represents a line that is perpendicular to the y-axis
A line perpendicular to the y axis will be a horizontal line, the equation of any horizontal line is y=b where b is the y-intercept.
In the given options
x=-6
y=x-4
y=5
and x=-2y
The only horizontal line is y=5
Hence, y=5 represents a line which is perpendicular to the y-axis
