Explain what is the difference between the solutions to 2x=10 and 2x > 10
Answer:
See explanation below
Step-by-step explanation:
Explain what is the difference between the solutions to 2x=10 and 2x > 10
Given the equations;
2x = 10
x = 10/2
x = 5
For the equation 2x > 10
x > 10/2
x > 5
The first equation has only one solution which is 5 while the second equation has infinite number of solutions since the values of x can take any value that is greater than 5

Andre says that 3 divided by 2/3 equals 4 and 1/3 because there are four groups of 2/3 and 1/3 left. Do you agree with Andre? Explain your reasoning.
Answer:
No I do not agree with Andre
Step-by-step explanation:
Andre says that 3 divided by 2/3
Solving for 3 ÷ 2/3
3 ÷ 2/3
= 3 × 3/2
= 9/2
= 4 1/2
Therefore, 3 divided by 2/3 is 4 1/2
Andre's reasoning is wrong.

Answer:
y = 0.2·0.5^x
Step-by-step explanation:
An exponential function is generally of the form ...
y = a·b^x
where 'a' is the function value when x=0, and b is the ratio between values for x=1 and x=0.
In the given table, y = 0.2 for x = 0, so a = 0.2.
We find that the value for x = 1 is 0.1, so the value of b is ...
b = 0.1/0.2 = 0.5
Then the exponential function is ...
y = 0.2·0.5^x

tan^2 70° -sec^2 70°
Answer:
-1
Step-by-step explanation:
We need to find the value of tan² 70° -sec² 70°.
We know that,
[tex]\sec^2\theta-\tan^2\theta=1[/tex] ...(1)
We can write the given expression as :
tan² 70° -sec² 70° = -(-tan² 70° +sec² 70°)
=-(sec² 70°-tan² 70°)
Using identity (1)
=-(1)
= -1
Hence, the value of the given expression is -1.

The points (0,4) and (1, 9) fall on a particular line. What is its equation in slope-intercept
form?
Answer:
The equation is y = 5x + 4.

Step-by-step explanation:
☆Remember: [tex]m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
☆Slope-intercept: [tex]y = mx + b[/tex]
---
☆We need to find the slope first. So just plug in according to the slope formula!
[tex]m = \frac{9 - 4}{1 - 0} = \frac{5}{1} = 5[/tex]
---
☆Now we need to find the y-intercept. We are going to plug in the slope and a set of coordinates to find the y-intercept.
[tex]y = mx + b \\ 9 = 5(1) + b \\ 9 = 5 + b \\ \frac{ - 5 = - 5 \: \: \: \: \: \: \: \: \: \: \: \: }{4 = b \: \: \: \: \: \: \: \: \: } [/tex]

☆Now all we need to do is plug in and we are done!

Find The sum or difference. Simplify 3/16 + 7/16
Find the equation of the linear function represented by the table below in slope-intercept form.
x y
-1 8
2 -1
5 -10
8 -19
Answer:
y = -x -3
Step-by-step explanation:
y value is decreasing which means negative slope
you can use slope formula to find slope
(y2-y1)/(x2-x1) = m
(-4-(-2))/(1-(-1)) = -1
m = -1
you can find y -intercept by plugging in slope and one coordinate into y=mx+b
-2 = -1(-1) + b
b = -3
The line passes through the point (-7,-5) and has slope of -8
Answer:
[tex]y=-8x-61[/tex]
Step-by-step explanation:
The slope-intercept form of the equation is y=mx+b where m is the slope and b is the y intercept. We know so far, that the slope is -8. We plug that in for m.
[tex]y=-8x+b[/tex]
Now, we need to find the y-intercept. The question gives us the point (-7,-5). We plug in -7 for x, and -5 for y.
[tex]-5=-8(-7)+b[/tex]
Then, we solve.
[tex]-5=56+b[/tex]
Subtract 56 from both sides.
[tex]-61=b[/tex]
Finally, we get this equation:
y=-8x-61

Consider the equation and the following ordered pairs: (−4,y) and (x,2).
y=2x+8
Step 1 of 2 : Compute the missing x and y values so that each ordered pair will satisfy the given equation.

Complete the table below.

row 1−4 Answer
row 2 Answer
2
Answer:
(-4, 0) and (-3, 2)
Step-by-step explanation:
Substitute each value into the equation.
Since x = -4 in the first ordered pair, to find y, you just put it into the equation as x:
y = 2(-4) + 8
y = -8 + 8
y = 0
The first ordered pair is (-4, 0)
Now, do the same for the second ordered pair. Substitute 2 for the y and solve for x:
2 = 2x + 8
-6 = 2x
x = -3
The second ordered pair is (-3, 2)
I hope this helps!
The missing coordinates in the ordered pairs are (-4, 0) and (-3, 2).
What are ordered pairs?An ordered pair (x, y) is used to represent the location of a point in coordinate geometry where x is the horizontal distance and y is the vertical distance of the point.
Given that, a line y = 2x+8, passes through two points (-4, y) and (x, 2) we need to find the value of x and y,
Since, the line is passing through the points therefore, the points will satisfy the equation of the line,
Put x = -4, in the equation,
y = 2(-4)+8
y = 0
So, the point is (-4, 0)
Put y = 2, in the equation,
2 = 2x+8
2x = -6
x = -3
So, the point is (-3, 2)
Hence, the missing coordinates in the ordered pairs are (-4, 0) and (-3, 2).
