Answer:
So draw a straight line. This measures as 180 degrees on your protractor. Align your protractor to the straight line, with the circle point in the middle of the line and notice the labels on the side. One of them, between 90 and 180 on the outer scale will measure as 135. Mark this on top of the paper, and remove the protractor. When you remove it, extend your mark to the middle of your line, and this gives you an obtuse angle of 135 degrees. Be sure to recheck!

Solve the system of linear equations by elimination.
−x+y=4
x+3y=4
please explain
Answer: y = 2 x = -2
Step-by-step explanation:
-x + y = 4
x + 3y = 4
Since x and -x are opposite, we can use the system of elimination
To do that, we add the first equation and the second equation together
-x + y = 4
+
x + 3y = 4
↓
4y = 8
Now we solve for y
4y = 8
Divide both sides by 4
y = 2
Since we now know y, we can solve for x by substituting y for 2 in one of the equations.
x + 3y = 4
Substitute y for 2
x + 3 (2) = 4
x + 6 = 4
Subtract 6 from both sides
x = -2

which of the options is a solution for the following system of inequalities
(2x+y>3 (x-y>1
(5,-2)
(0,5)
(0,0)
(0,-5)
Answer:
(5, - 2)
Step-by-step explanation:
2x+y>3
x-y>1
2x + y > 3 - - - - (1)
x - y > 1 - - - (2)
Using trial and error method :
Using :
(5,-2)
2x + y > 3
2(5) + (-2) > 3
10 - 2 > 3
8 > 3 (true)
x - y > 1
5 - (-2) >1
5 + 2 > 1
7 > 1 (True)
For 0,5
2x + y > 3
2(0) + (5) > 3
0 + 5 > 3
5 > 3 (true)
x - y > 1
0 - (5) >1
-5 > 1
--5 > 1 (false)
Also, all other options do not hold true for bitb inequality statements, hence answer is (5, - 2)

Consider the polynomial -4x+7x^3-5x^2+10
What is the degree of the polynomial? Explain. (1 point)
How many terms are in the polynomial? Explain. (1 point)
Write the polynomial expression in standard form.(
Answer:
Step-by-step explanation:
first lets put this in standard form to make it easier
[tex]7x^{3}[/tex] - [tex]5x^{2}[/tex] - 4x + 10
this form is the standard form (exponents go from greatest to least)
The degree in this polynomial is the highest exponent
So the degree is 3
There are 4 terms in this equation
7x^3
-5x^2
-4x
and 10

2. Bob the plumber charges $15 per hour plus a service fee of $40 for coming out to your house. Which function models this situation?
A) y=15x-40
B).y=15x+40
C) y=40x+15
D) y=15x
Answer:
B
Step-by-step explantion:
X is the amount of hours. Since they are charging 15 per hour you would have to multiply how many hours (x) by 15. Then add 40. And y equals the total amount pls mark brainliest

Step-by-step explanation:
A 12-foot ladder is leaning against a wall. The distance from the base of the wall to the base of the ladder is 6 StartRoot 2 EndRoot feet. Given this information, what can be determined about the triangle formed by the ground, wall, and ladder? Check all that apply. The triangle is isosceles. The leg-to-hypotenuse ratio is 1:StartRoot 2 EndRoot. The leg-to-hypotenuse ratio is 1:StartFraction StartRoot 2 EndRoot Over 2 EndRoot. The nonright angles are congruent. The ladder represents the longest length in the triangle.
Answer:
The leg-to-hypotenuse ratio is 1/√2
The ladder represents the longest length in the triangle.
Step-by-step explanation:
The set up in the question will b a right angled triangle
Length of the ladder will be the hypotenuse
The distance from the base of the wall to the base of the ladder is the adjacent
Height of the wall will be the opposite
Note that the longest side is always the hypotenuse (length of the ladder)
Given
length of the ladder = 12foot
The distance from the base of the wall to the base of the ladder = 6√2
The ratio of leg to hypotenuse = 6√2/12 = √2/2
√2/2 = √2/2 * √2/√2
√2/2 = √4/2√2
√2/2 = 2/2√2
√2/2 = 1/√2
Hence the leg-to-hypotenuse ratio is 1/√2
From the calculation the following are correct:
the leg-to-hypotenuse ratio is 1/√2
The ladder represents the longest length in the triangle.
Answer:
The leg-to-hypotenuse ratio is 1/√2
The ladder represents the longest length in the triangle.
The nonright angles are congruent

solve this .....................
Answer:
Step-by-step explanation: 3root5x^2 + 25x - 10root5 = 0
3xroot5 + 25x - 10root5 = 0 [ root x^2 = x]
28x root5 = 10 root5 [ -10root5 turns to 10 root5 when transferred to RHS]
28x root 5/root5 =10
28x=10
x = 10/28
x = 0.35

Y varies with x. When y=39, x=3. Find the value of y when x=2
Answer:
[tex] \frac{39}{y} = \frac{3}{2} \\ y = \frac{39 \times 2}{3} \\ \boxed{y = 26}[/tex]
26 is the right answer.The line AB is shown on the grid.
b)Find the equation of the line
perpendicular to AB and passing
through the midpoint of AB.
Step-by-step explanation:
a)
first step: find the gradient slope of line AB
A(-1,-2) B(7,2)
gradient=change in y/change in x
M=[2-(-2)]/[7-(-1)
M=4/8
M=1/2
the gradient of the straight line is given by
M1*M2=-1
1/2*M2=-1
multiply both sides by the reciprocal of 1/2
2*1/2*M2=-1*2
M2= -2.
b)
first find the mind point of line AB
A(-1,-2) B(7,2)
M.P=(x1+x2)/2 ,(y+y2)/2
M.P=(-1+7)/2 ,(-2+2)/2
M.P=6/2 ,0/2
M.P=3,0
ALSO THE GRADIENT PERPENDICULAR TO LINE AB IS;
M= -2
equation of a line perpendicular to AB and passes through the midpoint of AB
Y-Y1=M(X-X1). (3,0). M=-2
y-0=-2(x-3)
y= -2x+6
Melba buys 15 shirts for a total of
$60. Express this as an equation,
using 'x' as the cost of each shirt.
Then, solve the equation for the
value of 'x'.
Answer:
x = 4
Step-by-step explanation:
We need to divide:
(total cost) ÷ (number of shirts) = (cost per shirt)
$60 ÷ 15 = 4
