Answer: 1=65° and 5=43
Step-by-step explanation:
Question 1:
Angles on a straight line always add up to 180°.
So to find the angle of x on the first question you have to do 180-115=65°
You would have to use this method for questions 2, 3 and 4 as well.
Question 5:
Right angles always add up to 90° so to work out what x is you would have to do 90-47=43
You would have to use this method for questions 6, 7 and 8.
Hope this helps :)

Answers
Answer:
a=6
Step-by-step explanation:
write the equation as y=mx+b
y=-5/3x+b
solve for b
1=-5/3*-3+b
1-5=b
b=-4
Plug in -14 and solve for x
-14=-5/3x-4

FD≈25.94.. rounded = 26
Step-by-step explanation:
FD²=12²+(4x+11)²
FD²=144+16x²+88x+121
FD²=265+16x²+88x
also
FD²=12²+(13x-16)²
FD²=144+169x²-416x+256
FD²=400+169x²-416x
thus
265+16x²+88x = 400+169x²-416x
16x²-169x²+88x+416x+265-400 = 0
-153x²+504x-135 = 0
we will solve this quadratic equation by suing the quadratic formula to find x
x=(-504±sqrt(504²-4(-153)(-135)))/2(-153)
x=(-504±[tex]\sqrt{504^{2}-4(-153)(-135) }[/tex])/2(-153)
x=(-504±[tex]\sqrt{254016-82620 }[/tex])/-306
x=(-504±[tex]\sqrt{171396}[/tex])/-306
x=(-504±414)/-306
x=(-504+414)/-306 and x=(-504-414)/-306
x=-90/-306 and x=-918/-306
x= 5/17 , 3
substituting x by the roots we found
check for 5/17:
4x+11 = 4×(5/17)+11 = (20/17)+11 = (20+187)/17 = 207/17 ≈ 12.17..
13x-16 = 13×(5/17)-16 = (65/17)-16 = (65-272)/17 = -207/17 ≈ -12.17..
check for 3:
4x+11 = 4×3+11 = 12+11 = 23
13x-16 = 13×3-16 = 23
thus 3 is the right root
therfore
ED=23 and CD=23
FD²=FE²+ED² or FD²=FC²+CD²
FD²=12²+23²
FD²=144+529
FD²=673
FD=√673
FD≈25.94.. rounded = 26
Answer:
FD = 25.94 or 26Step-by-step explanation:
ED = CD ...... ( Tangent secant Property)
4x + 11 = 13x - 16
11 + 16 = 13x - 4x
27 = 9x
27÷9 = x
3 = x
so,
ED = 4x + 11 = 4(3) + 11
ED = 23
FE = 12 ...... ( given )
ΔFED = 90° ...... ( tangent property )
so,
FD² = FE² + ED²
FD² = 12² + 23²
FD² = 144 + 529
FD² = 673
FD = √673
FD = 25.94
FD = 26 (approx )
For what values of x is the expression below defined?
Sqrt x+5 divided by sqrt 1-x
Answers
Answer:
D. - 5 ≤ x < 1
Step-by-step explanation:
The numerator cannot be the square root of a neg. no.
So, x + 5 ≥ 0 or x ≥ -5
The denominator cannot be a neg. no. or 0.
So, 1 - x > 0
1 > x or x < 1
So, altogether - 5 ≤ x < 1
Therefore, D is the correct answer.

Complete question :
A pair of designer sneakers was purchased for $120. Since they were purchased, their price has increased by 15%. What is the new price?
Answer:
$138
Step-by-step explanation:
Given that :
Initial price = $120
Percentage increase in price = 15%
The new price of sneakers:
Initial price + (percentage increase in price * initial price)
New price :
$120 + (15% * $120)
New price :
$120 + (0.15 * $120)
New price of sneakers :
$120 + $18

Answer:
y = 2x - [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2 and c = - [tex]\frac{3}{4}[/tex] , then
y = 2x - [tex]\frac{3}{4}[/tex] ← equation of line
Answer: [tex]y=2x-\frac{3}{4}[/tex]
Step-by-step explanation:
We are going to have to put this into slope-intercept form
"y=mx+b"
m=slope
b=y-intercept
slope=2
y-intercept= [tex]-\frac{3}{4}[/tex]
Now we can put it all together, and remember the will always stay in the equation as it does not stand for anything.
[tex]y=2x-\frac{3}{4}[/tex]
