1.)
x + (x + 1) = 145
2x + 1 = 145
2x = 145 - 1
2x = 144
x = 72
if x is equal to 72
72 + 1 = 73
therefore the 2 integers is 72 and 73
2.
x + (x + 1) + (x + 2) = 54
3x + 3 = 54
3x = 54 - 3
3x = 51
x = 17
numbers are, 17, 18 and 19
Step-by-step explanation: To solve for x when the equation includes an exponent, start by isolating the term with the exponent. Then, isolate the variable with the exponent by dividing both sides by the coefficient of the x term to get your answer. If the equation has fractions, start by cross-multiplying the fractions.
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
y=x+2.05
This is a linear equation ( equation of a line)
To graph the line find the intercepts
<u>The y-intercept</u> is the value of y when the value of x is equal to zero
For x=0
y=0+2.05=2.5
The y-intercept is the point (0,2.05)
<u>The x-intercept</u> is the value of x when the value of y is equal to zero
For y=0
0=x+2.05
x=-2.05
The x-intercept is the point (-2.05,0)
To graph the line plot the intercepts and then join the points
using graphing tool
see the attached figure
Answer:
true
Step-by-step explanation:
you must assume its false and if said statement leads to an impossibility then its proved to be true
