-2x + 4 < 16
Help me please I didn’t pay attention
Answer:
I think it’s done like this, I’m not sure
First, collect the like terms
-2x<16-4
-2x<12
x<12/-2
x<-6
So, you substitute -6 instead of x to find which is greater
12+4<16
16<16
Which makes it false
Step-by-step explanation:
I hope I explained well, please give me brainliest
The solution of the inequality - 2x + 4 < 16 will be;
⇒ - 6 < x
What is Inequality?
A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
The inequality is,
⇒ - 2x + 4 < 16
Now,
Solve the expression as;
⇒ - 2x + 4 < 16
Subtract 4 both side, we get;
⇒ - 2x + 4 - 4 < 16 - 4
⇒ - 2x < 12
Divide by 2 , we get;
⇒ - x < 6
Multiply by - 1, we get;
⇒ x > - 6
⇒ - 6 < x
Thus, The solution of the inequality - 2x + 4 < 16 will be;
⇒ - 6 < x

1-12 <1-20). Is Leslie correct? Explain why or why not.
Answer:
Leslie is NOT correct
Step-by-step explanation:
Leslie thinks that the number closer to 0 that's in the negatives it smaller because the number is smaller. But actually, the number farther from 0 that's in the negatives is smaller. So, -12 °C is warmer than -20 °C

s/-4 = 6
what is the value of s?
Answer:
s = −24
Step-by-step explanation:
Step 1 : Move the negative sign to the left.
[tex]-\frac{s}{4} =6[/tex]
Step 2 : Multiply both sides by 4.
−s = 6 × 4
Step 3 : Simplify 6 × 4 to 24.
−s = 24
Step 4 : Multiply both sides by −1.

Judy has 2 3/4 bags of rock that she wants to use in her yard. Each bad will cover 310.2 sq ft. How many square feet will Judy be able to cover if she used all the bags of rocks? Round up your answer to the neatest tenth place.
Answer:
853.1 sq ft
Step-by-step explanation:
Total bags of rock = 2 3/4
Each bag will cover 310.2 sq ft
How many square feet will Judy be able to cover if she used all the bags of rocks?
Total Square feet covered = number of bags of rock × area covered by each bag
= 2 3/4 × 310.2 sq ft
= 11/4 × 310.2 sq ft
= 853.05 sq ft
To the nearest tenth
= 853.1 sq ft

The graph of g is a horizontal stretch by a factor of 2 and a translation 2 units up, followed by a reflection in the y-axis of the graph of
f(3) = 8x2 - 6. Write a rule for g. Then identify the vertex.
The vertex is
Answer:
f(x)=8x^2-6
f(x) = a (x -h)2 + k
horizontal stretch by a factor of 2 -> 1/2 x
2 units up -> k = 2
reflection in y axis -> x value is negative
g(x) = 8*(1/2 x)2 - 6 + 2
g(x) = 2 x2 -4
Step-by-step explanation:
The vertex will be at g(x) = 2x² -4.
What is a graph?A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data. A function is defined as the expression that set up the relationship between the dependent variable and independent variable.
Given that the graph of g is a horizontal stretch by a factor of 2 and a translation 2 units up, followed by a reflection in the y-axis of the graph of
f(3) = 8x² - 6.
f(x)=8x²-6
f(x) = a (x -h)2 + k
Horizontal stretch by a factor of 2 -> 1/2 x
2 units up -> k = 2
Reflection in y axis -> x value is negative.
g(x) = 8 x (1/2 x)² - 6 + 2
g(x) = 2x² -4
Therefore, the vertex will be at g(x) = 2x² -4.

You are at a fruit stand to get some fresh produce. You notice that the person in front of you gets 5
apples and 4 pears for 10 dollars. You get 5 apples and 5 pears for 11 dollars. Write a system of
equations that could be used to find the price of an apple and the price of a pear.
Answer:
[tex]5A + 4P = 10[/tex]
[tex]5A + 5P = 11[/tex]
1 apple costs $1.2
1 pear costs $1
Step-by-step explanation:
Represent Apples with A and Pears with P
For the person in my front, the expression is:
[tex]5A + 4P = 10[/tex]
For me, the expression is
[tex]5A + 5P = 11[/tex]
Hence, the system of equation is:
[tex]5A + 4P = 10[/tex]
[tex]5A + 5P = 11[/tex]
Solving for the values of A and P.
Substract equation (2) from (1)
[tex]5A - 5A + 4P - 5P = 10 - 11[/tex]
[tex]-P = -1[/tex]
[tex]P = 1[/tex]
Hence, 1 pear costs $1
Substitute 1 for P in [tex]5A + 4P = 10[/tex]
[tex]5A + 4 * 1 = 10[/tex]
[tex]5A + 4 = 10[/tex]
[tex]5A = 10 - 4[/tex]
[tex]5A = 6[/tex]
[tex]A = \frac{6}{5}[/tex]
[tex]A = \$1.2[/tex]
Hence, 1 apple costs $1.2

Transform the equation.
Stretch y=5x by a factor of 3
What is the transformed equation?
Transform the equation.
Shift y=5√x+5 horizontally, 5 units to the right and a stretch by a factor of 4
What is the transformed equation?
Answer:
1. I assume that stretching vertically by factor of 2 means that every point on the transformed curve is twice as far from the x axis as the original curve.
Imagine that you have plotted y=5x. you want to change the y scale so that each point on the original curve is two times as high. For example, one point on the original curve is (1,5). This point must be relocated to (1,10). Similarly, the point (2,10) on the original curve must be relocated to (2,20).
You can see that these relocations are accomplished if we transform the function to y=2(5x)=10x.
