Answer:
m∠A = 90°
Step-by-step explanation:
In isosceles triangle base angles are congruent. That means we can equate measurments of angle B and angle C and solve for x!
m∠B = m∠C
11x - 10 = 7x + 10
4x - 10 = 10
4x = 20
x = 5
Now let's insert x back in the expressions for angles.
m∠B = (11x − 10)° = (11(5) − 10)° = 45°
m∠C = (7x + 10)° = (7(5) + 10)° = 45°
<u>Sum of all angles in the triangle is 180°.</u> Let's make an equation.
m∠A + m∠B + m∠C = 180°
m∠A + 45°+ 45° = 180°
m∠A = 90°

Step-by-step explanation:
84 = 2 * 2 *3 * 7
Answer:
-3(4 - 6x)
-12 +18x
=18x - 12
Step-by-step explanation:
You multiple the negative 3 with positive 4 to get negative 12.
An you also multiple the negative 3 with negative 6x (a negative multiple a negative changes into positive) giving you 18x as your answer
Answer:
The top one I'm pretty sure.
Answer:
(a) and (f)
Step-by-step explanation:
Given
See attachment for table and options
First, we calculate the slope of the table
Using:
So, we have:
The equation is then calculated using:
This gives:
So, we have:
--- The given equation
and
--- The equation of the table
An equation is represented as:
Where:
m = slope or rate of change
b = y intercept
So, for the given equation:
Rate of change = 5
y intercept = 12
For the table:
Rate of change = 12
y intercept = 5
In conclusion:
(a) has the greater rate of change:
and
(f) has the greater y intercept
