Help me please, i need to get my grade up from a 28 in my class
Answers
Answer:
y = f(x+3) - 5.
Step-by-step explanation:
In general, the equation y = f(x-h) + k shifts the graph of f(x) h units to the right and k units upward. This graph shifts f(x) 3 units to the left (-3 units to the right) and 5 units downward (-5 units upward).
Therefore, the equation for the shifted graph is y = f(x-(-3)) + (-5), or simply y = f(x+3) - 5.

One variable linear equation is an equation that has a variable and the exponent number is one.
Can be stated in the form:
or
ax + b = c, where a, b, and c are constants, x is a variable
Whereas the two-variable linear equation is a linear equation that has 2 variables and the exponent is one
Can be stated in the form:
x, y = variable
In the statement of the task:
Kevin is 3 times as old as Daniel.
Let Kevin = K, Daniel = D
then the age comparison :
K = 3D ⇒ equation 1
4 years ago, Kevin was 5 times as old as Daniel
then the equation becomes
K-4 = 5 (D-4)
K-4 = 5D-20
K = 5D-16 ⇒ equation 2
Both of these equations are equations that have 2 variables, so the solution can be used in 3 ways:
1. graph system
the solution is the intersection point of the two equations / lines.
2. substitution
the solution is we change one variable into another variable form of an equation, then substitutes that variable in another equation
3. elimination
the solution is to eliminate one variable from the equation system.
to determine the variable x we eliminate the variable y first, or vice versa.
We use the second method: substitution

I will give brainiest to the answer with step-by-step explanation :
Answers
Answer:
10x^2+7x+1
Step-by-step explanation:
Let's simplify this step-by-step.
3x^2+5x−9+7x^2+2x+10
=3x^2+5x+−9+7^x2+2x+10
After, combine like terms. (Simplify the expression)
Here is a step-by-step row.
= 3x^2+5x+-9+7x^2+2x+10
= (3x^2+7x^2)+(5x+2x)+(-9+10)
= 10x^2+7x+1
That is the most simplified form, I hope this helped!

Show and explain how you found the answer to this problem. Carla has 152 pictures to put in a scrapbook. If she can fit 12 pictures on a page, how many pages will she need to use?
Someone explain how did it in there answer :)
I’ll also mark as you know that
Answers
Explanation:
You make the equation. If she can put 12 on each page then you would multiply 12 by p (pages) and have it equal to 152
152=12p
To solve this, you would divide 12 from both sides
152/12=12.666
Therefore, 12.6=pages but since there aren’t 12.6 pages and you need to keep it a whole number you would round up to 13 because if you kept it at twelve pages you would have those pictures left over.
Answer:
13 pages

The length of a rectangle is 4 more than the width. If the perimeter is 36 inches, what’s the width and length of the rectangle?
Answers
Answer:
7 inches
Step-by-step explanation:
Answer:
The width and the length of the rectangle is...
Step-by-step explanation:
If we are looking at the total Perimeter of the rectangle, which is 36 inches, then we have to take in the information of the '4 more than the width'. so we need to think of the numbers that would make sense in this scenario. the formula to solve this would be:
w + (l + 4 ) x 2 = 36
So we would need to look at the different scenarios that don't go over 18.
if the width = 7
and the length = 11
7 + 11 = 18
18 x 2 = 36.

Eight more then seventimes a number (x) is atleast twenty nine
Answers
Answer:A number increased by seventeen is equal to seventy-three. x + 17 = 73
Some number decreased by seven is thirty-three. x - 7 = 33
A number increased by twelve is forty. x + 12 = 40
A number increased by fifteen is sixty-two. x + 15 = 62
Eight less than a number is nine. x - 8 = 9
A number divided by 11 is 4. x/11 = 4
Seven more than three times a number is 19. 3x + 7 = 19
Four more than five times a number is thirty-six. 5x + 4 = 35
Eight less than nine times a number is eleven. 9x - 8 = 11
Twelve more than four times a number is seven. 4x + 12 = 7
Seven more than triple a number is fifteen. 3x + 7 = 15
Seven times a number increased by eight equals twenty-three. 7x + 8 = 23
Eight more than six times a numbers is eleven. 6x + 8 = 11
Nine times a number increased by thirteen is twelve. 9x + 13 = 12
The quotient of a number and four is seventeen. x/4 = 17
A number increased by seven is twenty-five. x + 7 = 25
Fifty-five is the sum of a number and sixteen. x + 16 = 55
The product of a number and eleven is seventy-five. 11x = 75
Eight times a number increased by eleven is thirty-seven. 8x + 11 = 37

In the rectangular prism, PQ is the diagonal. Find the length of
PQ given PR = 7, RS = 4, and QS = 4.
A 4
B 9
C 12
D 15
Answers
Answer:
Option (B)
Step-by-step explanation:
Length of PR = 4
RS = 4
QS = 4
For the length of PT,
PT² = RT² + PR² [Since, PT is the diagonal of rectangle PRT]
PT² = QS² + PR² [Since, RT ≅ QS]
PT² = 4² + 7²
PT² = 16 + 49
PT² = 65
Now for the length of PQ,
PQ² = QT² + PT²
PQ² = RS² + PT² [Since, QT ≅ RS]
PQ² = 4² + 65
PQ² = 16 + 65
PQ = √81
PQ = 9
Therefore, length of diagonal PQ is 9 units.
Option (B) will be the answer.
