Step-by-step explanation:
We need to use inverse operations to isolate x by itself.
The inverse of addition is subtraction so we can subtract 2 from both sides
[tex]5x + 2 - 2 = 22 - 2[/tex]
[tex]5x = 20[/tex]
Divison is the inverse of multiplication so we can divide 5 by both sides to find the answer of x.
[tex] \frac{5x}{5} = \frac{20}{5} [/tex]
[tex]x = 4[/tex]
We can plug 4 in for a to verify it
[tex]5(4) + 2 = 22[/tex]
[tex]20 + 2 = 22[/tex]
[tex]22 = 22[/tex]
So it is true.
How can all the solutions to an equation in two variables be represented?
How are solutions to a system of nonlinear equations found?
How do linear, quadratic, and exponential functions compare?
How can solutions to a system of nonlinear equations be approximated?
How do linear, quadratic, and exponential functions compare?
Answer:
How can all the solutions to an equation in two variables be represented?
The solution to a system of linear equations in two variables is any ordered pair x,y which satisfies each equation independently. U can Graph, solutions are points at which the lines intersect.
How can all the solutions to an equation in two variables be represented?
you can solve it by Iterative method and Newton Raphson's method.
How are solutions to a system of nonlinear equations found?
Solve the linear equation for one variable.
Substitute the value of the variable into the nonlinear equation.
Solve the nonlinear equation for the variable.
Substitute the solution(s) into either equation to solve for the other variable.
How can solutions to a system of nonlinear equations be approximated? U can find the solutions to a system of nonlinear equations by finding the points of intersection. The points of intersection give us an x value and a y value. Using the example system of nonlinear equations, let's look at how u can find approximate solutions.
Answer:
How do linear, quadratic, and exponential functions compare?
Use differences or ratios to tell whether the table of values represents a linear function, an exponential function, or a quadratic function.

Find the missing angle measurement.
Answer:
X=69
Step-by-step explanation:
Angle cab is found by subtracting 127 from 180 (will make 53), angle cba is vertical angles with fbe (which has the value of 58) so it is also 58 degrees. Subtract 58 and 53 from 180 to get 69.

A 22.5 cm straw fits diagonally inside an 18 cm high can of soft drink what is the radius of the can
Answer:
6.75cm
Step-by-step explanation:
The straw fits diagonally inside the can so it makes a right angled triangle with height and base of the can ( which is the diameter of the can)
So, hypotenuse = length of straw = 22.5cm
perpendicular = 18cm
base = diameter of can(d)
Using pythagoras theorem
h² = p² + b²
(22.5)² = 18² + d²
506.25 = 324 + d²
d² = 506.25 - 324
d² = 182.25
d = 13.5cm
Now radius = d/2 = 13.5/2 = 6.75cm
Tyler spent a relaxing afternoon watching movies. He watched movies for 2 1/2 hours. His brother watched the movies for 3/4 of the amount of time that Tyler did. What equation can be used to find out how much time Tyler’s brother spent watching movies?
Answer:
1 3/4
Step-by-step explanation:
Frist he turned the proper fraction into an inproper which came to be 5/2. Then he subtracted 5/2 out of 3/4 Then after that you get 7/4 but then you make it a proper fraction you will get 1 3/4

Step-by-step explanation:
Top Right:
Find the angles in the triangle to find y
180-112= 68 - this is the top angle of the triangle
x = must be corresponding to the angle next to 127
so do 180 -127 = 53 = x
180 - (53 + 68) = 59 = y
Answer:
The bottom right
x = 129
180-59 = 129
129 = x (vertically opposite angles)
y = 47

After 5 games Adrian Peterson has rushed for 498 yards. If he gains 4.5 yards per carry, how many carries will it take for him to reach 1200 yards
Answer:
156 carries
Step-by-step explanation:
Given that:
5 games = 498 yards
Number of yards Gained per carry = 4.5 yards
Target number of yards = 1200
Number of yards left to reach target :
1200 - 498 = 702 yards
Number of carries required = number of yards / yards per carry
Number of carries required = 702 / 4.5
= 156 carries

13. A cone with a radius of 3 inches and a height of 7 inches has the same radius as a cylinder. If the cylinder's volume is two times the volume of the cone, what is the height of the cylinder? Use 3.14 for pi
Answer:
Step-by-step explanation:
r = 3 in
h = 7 in
volume of cone = ⅓πr²h = 21π in³
cylinder has radius r = 3 and height h.
volume of cylinder = πr²h = 9πh in³
volume of cylinder is two times the volume of cone
9πh = 2×21π
9h = 42
h = 42/9 = 4⅔ in

Answer:
r = [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
The common ratio (r) of a geometric sequence is the ratio of any term divided by the previous term , then
r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{160}{640}[/tex] = [tex]\frac{1}{4}[/tex]

Naomi‘s parents want to have $50,000 say to her college education if they invest $20,000 today in earn 7% interest compounded annually about how long will it take them to save the $50,000
Answer:
13 years
Step-by-step explanation:
Given data
A=50,000
P=20,000
r= 7%
t=??
The compound interest formula is given as
A=P(1+r)^t
Calculate time, solve for t
t = ln(A/P) / r
t= ln(50000/20000)/0.07
t= ln(2.5)/0.07
t= 0.916/0.07
t= 13.0
Hence the time is 13 years
