Answer:
see below
Step-by-step explanation:
Add 4 to find the solution:
z ≤ 7
The value 7 is included in the solution set, so there will be a solid dot at that point. Numbers less than 7 are also included in the solution set, so the number line will be shaded to the left of that solid dot.
Answer:
33/4
Step-by-step explanation:
Let the first number be x, and the second number be y.
x - y = 4
x + y = -7
Solve for x in the first equation.
x - y = 4
x = 4 + y
Put x as (4 + y) in the second equation and solve for y.
4 + y + y = -7
4 + 2y = -7
2y = -7 - 4
2y = -11
y = -11/2
Put y as -11/2 in the first equation and solve for x.
x - y = 4
x - (-11/2) = 4
x + 11/2 = 4
x = 4 - 11/2
x = -3/2
Their product is:
-11/2 × -3/2
33/4
Answer:
B
Step-by-step explanation:
The base angles are congruent because it's an isosceles triangle the base angles would both equal 81
Answer:
Step-by-step explanation:
We want to find the equation of the line that goes through: !6,-10) and is perpendicular to the line
Let's simplify the equation of the line to get:
The slope of this line is -5.
The perpendicular to this line has a slope of
The equation going through (6,-10) is
We substitute to get;
Expand;
