Answer:
last option is correct
Step-by-step explanation:
A step that could be used to find the solution is substitution.
We can directly substitute for c in equation F
Since c= 2d + 1 from equation E, we can substitute directly in equation F and we will have 2d + 1 = 3d + 7

Answer:
1
Step-by-step explanation:
You have to rewrite this into slope intercept.
Find Y
Therefore, the y intercept is 1
Alisha's Answer:
The Slope ( m ) = 6
Answer:
Alisha might have not taken respective input values with the output values and the correct slope is 3.
Step-by-step explanation:
The general form of a linear relationship is given by the equation
Here m is the rate of change of the linear relationship which is calculated as:
Change in y is given by the difference of two outputs and x is given by difference of two inputs
So taking the set of outputs and inputs
(1,2) and (2,5)
Alisha might have not taken respective input values with the output values and the correct slope is 3.

Answer:
a. Rational number 1.26
Simplest radical 3−√3
b. Simplest radical 28+10√3
Rational number 45.32
c. Rational number 89
Step-by-step explanation:
a. √3(√3-1)
To get the simplest radical
Apply the distributive property.
√3*√3-√3
Combine using the product rule for radicals.
√3*3+√3*−1
Move −1 to the left of √3.
√3*√3*3-1*√3
Multiply 3 by 3.
√9−1*√3
Rewrite 9 as 3^2
√3^2-1 *√3
Pull terms out from under the radical, assuming positive real numbers.
3−1*√3
Rewrite −1√3 as −√3.
3−√3
Rational number 1.26
b. (5+√3)²
Expand
(5+√3)²= 25 +5*√3+5*√3+3= 28 +10√3
Simplest radical 28+10√3
Rational number 45.32
c. (10+√11)(10-√11)
Expand
(10+√11)(10-√11)= 10*10+ 10*-√11+10*√11+√11*-√11
=100+ 10*-√11+10*√11- 11
=89- 10*√11+10*√11
=89
