Answer:
15. x = 112 degrees
18. x = 120 degrees
Step-by-step explanation:
15.
A triangle's angles always equal 180 degrees so we can find the two unknown angles by subtracting 44 from 180 and then dividing it by 2.
2a + 44 = 180
2a = 136
a = 68
Each unknown angle equals 68 degrees. The line from 44 degrees to x degrees segments a line that has a 180 degree angle so we can subtract 68 from 180 to get x.
x + 68 = 180
x = 112
18.
We can use the same concept here but now every angle equals each other so we can divide 180 by 3 to get the measure of those angles.
3a = 180
a = 60
Now we do the same thing as last time to find x.
x + 60 = 180
x = 120

2x^2-y if x=3 and y=8
Answers
Answer:
= 10
Step-by-step explanation:
x = 3
y = 8
just replace that x and y with the values given
[tex]2x^{2}[/tex] - y
2 ([tex]3^{2}[/tex]) - 8
2 (9) -8
18 - 8
= 10
Because of PAMDAS you do 3 to the second power first which equals 9. 9x2 is 18. And then 18 - 8 = 10. In all, You just plug x and y in and then solve by PAMDAS.

Find the measures of the indicated angles pictures included!!!
Answers
Answer:
25
Step-by-step explanation:
The angles b and 65 are complementary, meaning they sum to 90 degrees. You know this because those 2 angles and the right angle are sitting on a straight line. So, together they equal 180 and 180-90 is 90. Therefore, angle b+65 must equal 90. So, simply subtract 65 from 90 to get the answer, 25.

Use the drop-down menus to complete the statements about whether each student's
answer is an equivalent expression.
Then choose an expression that is equivalent
Answers
Answer:
Tessa's expression is false because -7 times -4 is positive 28, not -28.
Bernette's expressionis false because you must distribute the -7 before subtracting 7 from 2 (peMdas)
Lucy's expression is true because she correctly distributed the -7 to each of the terms in the parentheses and used PEMDAS.
2-21x+28
The equivalent expression for the given expression is 2-21x+28.
What is an equivalent expression?Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.
Tessa:
2-7(3x-4)=2-21x-28
Tessa's equivalent expression is wrong. Because -7×(-4)=28 not -28.
Bernette:
2-7(3x-4)=-5(3x-4)
Bernette's equivalent expression is wrong. Because, you can not 2 and 7, since 7 is multiplied to the term 3x-4
Lucy:
2-7(3x-4)=2-21x+28
Lucy's equivalent expression is correct.
Therefore, the equivalent expression is 2-21x+28.

Answers
Answer:
A. the slope value is 1/4
B. 0
C. y = 1/4x
Step-by-step explanation:
A: the slope can be calculated with the formula
[tex]m = \frac{rise}{run} = \frac{y2 - y1}{x2 - x1} [/tex]
m is the slope
(x1, y1) is your first coordinate point (any point will work)
(x2, y2) is your second coordinate point (any point will work)
Plug in your values, in this case I chose (0,0) and (4,1) as the two coordinates:
[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{1 - 0}{4 - 0} = \frac{1}{4} [/tex]
B: the y-intercept is the y-coordinate of where the graph touches the y-axis and in this case the coordinate is (0,0) where the y coordinate is 0.
C:
the equation of the graph is y = mx + b.
m is the slope = 1/4
b is the y-intercept = 0
Therefore the equation is y = 1/4x

determine b so that the line with equation 5x + by - 6 = 0 is perprdicular to the line with equation 7y = 4x + 7
Answers
9514 1404 393
Answer:
b = 20/7
Step-by-step explanation:
The slope of the first line can be found by solving for y:
by = -5x +6 . . . . . . add 6-5x
y = -5/b +6/b . . . . . divide by b
The slope is -5/b.
The slope of the second line can be found by solving for y:
7y = 4x +7
y = 4/7x +1 . . . . . . divide by 7
The slope is 4/7.
For the lines to be perpendicular, the product of these slopes must be -1:
(-5/b)(4/7) = -1
-20/(7b) = -1 . . . . simplify
b = 20/7 . . . . . . . multiply by -b
The lines will be perpendicular when b = 20/7.

C.
x-intercept = 3, y-intercept = -2
D.
x-intercept = 4, y-intercept = 3
Answers
Explanation:
Notice that when x = 0 the value of y is 3/-1 so this line "cuts" the y axis at y=-3.00000
y-intercept = 6/-2 = 3/-1 = -3.00000
When y = 0 the value of x is 2/1 Our line therefore "cuts" the x axis at x= 2.00000
x-intercept = 6/3 = 2

y=-x+2
y=-3x-2
Answers
Answer: (-2, 4)
Concept:
There are three general ways to solve systems of equations:
Elimination: using addition/subtraction to cancel out variables.Substitution: when two variables appear in both equations and are isolated, they could substitute each other.Graphing: graph the equations to find the intersection for the solution.Here we are going to use substitution since the variable [y] is being isolated in both equations.
Solve:
Given equations
y = -x + 2
y = -3x - 2
Using the method of substitution to combine the equations
-x + 2 = -3x - 2
Add 3x on both sides
-x + 2 + 3x = -3x - 2 + 3x
2x + 2 = -2
Subtract 2 on both sides
2x + 2 - 2 = -2 - 2
2x = -4
Divide 2 on both sides
2x / 2 = -4 / 2
[tex]\boxed{x=-2}[/tex]
