Find the value of x.
Answer:
x= 37.5°
Step-by-step explanation:
∠CBD
= 180° -75° (adj. ∠s on a str. line)
= 105°
∠BCD= ∠BDC (base ∠s of isos. △BCD)
∠BCD= x
∠BCD +∠BDC +∠CBD= 180° (∠ sum of △BCD)
x +x +105°= 180°
2x= 180° -105°
2x= 75°
x= 37.5°
Alternative working:
∠BDA= (180° -75°) ÷2 (base ∠s of isos. △ABD)
∠BDA= 52.5°
∠BDA +∠BDC= 90°
52.5° +x= 90°
x= 90° -52.5°
x= 37.5°

how to solve -6x+5y=16 and x=5-3y using subsituation
Answer:
you already have x solved for so you plug 5-3y into the x in -6x and you get -6(5-3y)+5y=16
-30+18y+5y=16
-30+23y=16
23y=46
y=2
x=5-3(2)
x=5-6

Solve the following algebraic expressions
1) n(n-4) -n(5-n)
2)
Answer:

Hope it helps
Answer:
[tex]\huge\boxed{1) 2n^2-9n}[/tex]
[tex]\huge\boxed{2) 6c\³ + 4c\²}[/tex]
Step-by-step explanation:
Part 1:
= n(n-4)-n(5-n)
By distributive property
= n² - 4n - 5n + n²
= 2n² - 4n - 5n
= 2n² - 9n
Part 2:
= 4c(3c-c²)-2c²(4-5c)
Distributing brackets
= 12c² - 4c³ - 8c² + 10c³
Combining like terms
= 12c² - 8c² - 4c³ + 10c³
= 4c² + 6c³
= 6c³ + 4c²

Answer:
y = 6/7x - 37/7
Step-by-step explanation:
m = 6/7
(5, -1)
y - y1 = m(x - x1)
y + 1 = 6/7(x - 5)
y + 1 = 6/7x - 30/7
y = 6/7x - 37/7
Answer:
Step-by-step explanation:
Start by the point-slope form and given slope = 6/7 and point (5, -1)
(y-(-1)) / (x-5) = 6/7
7(y+1) = 6(x-5)
7y = 6x - 37
y = 6x/7 - 5 2/7
which is the answer in slope-intercept form

Which equation represents a line that is parallel to the line represented by
4x + y = 7 and passes through the point (1, 8)?
Answer:
y = -4x + 12
Step-by-step explanation:
For a line to be parallel, it needs to have the same slope.
Point intercept form: y - y₁ = m (x - x₁)
Where y and x are just kept as y and x, y₁ and x₁ are the parts of a coordinate, and m = slope.
So, in order for the line to be parallel, it needs to have the same slope as the first equation. The slope of the line (which is the "m" in y = mx + b) is..
4x + y = 7
y = -4x + 7
So, m, or the slope, is -4.
Plug this, along with the coordinate the problem gives you into point-intercept form.
y - y₁ = m (x - x₁)
y - 8 = -4 (x - 1)
Simplify.
y - 8 = -4x + 4
Add 8 to both sides.
y = -4x + 12
I need help finding the slope
y2- y1 / x2 - x1

Devonte opens a savings account by making a deposit of $249.45. Every week, he deposits another $31.75 in the account. Which expression shows the amount of money that will be in the account w weeks after the account is opened? 249.45 w + 31.75 249.45 w minus 31.75 249.45 + 31.75 w 249.45 minus 31.75 w
Answer:
249.45 + 31.75w
Step-by-step explanation:
Opening deposit = $249.45
Weekly deposit made into account = $31. 75
Amount of money which will be in account w weeks after opening :
Opening deposit + (weekly deposit * number of weeks)
Amount after w weeks :
$249.45 + (31.75 * w)
$249.45 + 31.75w

Which exponential function matches the table?
Answer:
B: f(x) = 27[tex](\frac{1}{3})^{x}[/tex]
Step-by-step explanation:
If you substitute 0 and 1 into each given exponential function. The first, second and fourth value with 0 substituted will give 27 as such, so we can eliminate the third exponential function. But, if you substitute 1 into all of the remaining possible exponential functions, the only function that will give you 9, when x = 1 is substituted, is B: f(x) = 27[tex](\frac{1}{3})^{x}[/tex].
I hope this helps you!! ^-^
