Answer:
2.) yes
3.) x=3
Step-by-step explanation:
2.) if u plug in 2 into the x-value, then the y-value equals to 5 (so it's correct)
3.)
y = 6
2x + 6 = 12
x = 3
Answer:
a. x=8
b.Step 1: Simplify both sides of the equation.
2(2x−2)=4x−4
(2)(2x)+(2)(−2)=4x+−4(Distribute)
4x+−4=4x+−4
4x−4=4x−4
Step 2: Subtract 4x from both sides.
4x−4−4x=4x−4−4x
−4=−4
Step 3: Add 4 to both sides.
−4+4=−4+4
0=0
Answer:
All real numbers are solutions.
c. Step 1: Simplify both sides of the equation.
3(x+1)=4x+7−x
(3)(x)+(3)(1)=4x+7+−x(Distribute)
3x+3=4x+7+−x
3x+3=(4x+−x)+(7)(Combine Like Terms)
3x+3=3x+7
3x+3=3x+7
Step 2: Subtract 3x from both sides.
3x+3−3x=3x+7−3x
3=7
Step 3: Subtract 3 from both sides.
3−3=7−3
0=4

Answer:
amount = £1415.57
Step-by-step explanation:
given data
computer buy = £1600
depreciates rate = 4% per year
time = 3 year
solution
we get here amount that is express here as
amount = P × ...................................1
here r is rate and t is time put here value
amount will be
amount = 1600 ×
solve it we get
amount = £1415.57
Answer:
The missing side is 18 inches
Step-by-step explanation:
Since in the smaller rectangle the sides are 2.5in x 6in and one side for the larger rectangle is given, you can make an equation.
Then you can cross multiply.
2.5x=45
Divide by 2.5 on both sides.
x= 18
Answer:
a) Bar chart
b) Histogram
c) Bar chart
d) Histogram
Step-by-step explanation:
a) Trash pick-up DAY for each HOUSEHOLD in Ames - This is categorical data because, we are talking about days of the week. For instance, Household 1 might have Sunday as Trash pick-up day and that could be accumulated into frequency. Hence, BAR chart is the most appropriate.
b) Patient WAIT-TIME at ISU. This is continuous (quantitative) data. And the most appropriate is HISTOGRAM.
c) Number of trips taken during a GIVEN SCHOOL YEAR by EACH ISU STUDENT. Let say we have 5 ISU STUDENTS. Student 1 had 5 trips, student 2 had 10 trips, etc.
We want to see which student has the most and least trip in that particular school year. Although is count data but the most appropriate graphical display is BAR chart.
d) TAX BRACKET of ALL Iowa RESIDENTS. This is a continuous (quantitative) data. The most appropriate graphical display is HISTOGRAM.
