what is this plx help???/?
Answer:
B) 9 square units
Step-by-step explanation:
Split the shape into a right triangle and a rectangle.
The rectangle is 2 by 3, so multiply 2 x 3 for the area: 6.
The triangle has a height of 3 and a base of 2. Multiply to get 6. Then divide by 2 to get: 3.
Add 6 + 3 to get 9 square units.
Hope it helps!
Determine the maximum or minimum value of the following quadratic function. LaTeX: f\left(x\right)=-3\left(x+5\right)^2-1f ( x ) = − 3 ( x + 5 ) 2 − 1
Answer:
Step-by-step explanation:
[tex]y=-3(x^2+10x+25)-1\\ \\ y=-3x^2-30x-76\\ \\ dy=-6x-30\\ \\ d^2y=-6\\ \\ \text{Since the second derivative is always negative, when the first derivative is equal to zero the function will be at a global maximum.}\\ \\ dy=0=-6x-30\\ \\ x=-5\\ \\ f(-5)=-1\\ \\ \text{So the global maximum occurs at the point (-5,-1)[/tex]

2(3x -8y) - 6 =
Answer:
6x - 16 y -6
Step-by-step explanation:
okay so first you have to distribute the 2 to the number inside the parenthesis
2(3x-8y) -6
you do 2 x 3x, which is 6x
then 2 x -8y, which is -16y
Now the new equation is 6x - 16 y -6
There you go!!

Sorry I’m only in 8th grade and can’t figure it out
Step-by-step explanation:
Consider the following expression and determine which statement are true.
Answer:
A and B
Step-by-step explanation:
A is correct because the three terms are x², 5yz, and -8.
B is 100% correct I guarantee it.
C is incorrect because ² is not a coefficient.
D is incorrect because there are three factors in that multiplication term: 5, y, and z.

You put $500 in an account. The
account earns $55 simple interest in 5
years. What is the annual interest
rate?
HURRY HELP
Answer:
2.2% per year
Step-by-step explanation:
Problem:
You deposit $500 into a bank account and received $55 simple interest after 5 years. What had been the interest rate?
Result:
The interest rate was 2.2% per year.
Explanation:
Find interest rate by using the formula I = P*i*t , where I is interest, P is total principal, i is rate of interest per year, and t is total time in years. In this example I = $55, P = $500 and t = 5 years, so
i = 55/500*5
i=0.022 = 2.2% per year
Hope it helps XD

How do I complete the square for 4x^2+ 8x-5= 0?
Answer:
man I have no idea dude I don't really know squares if you're talking about square root I really don't know
Answer:
x = [tex]\frac{1}{2}[/tex], - [tex]\frac{5}{2}[/tex]
Step-by-step explanation:
This is not so fun!
[tex]4x^{2} + 8x - 5 = 0\\[/tex]
Step 1: Move the 5 to the right side
[tex]4x^{2} +8x = 5[/tex]
Step 2: Divide thru by 4
[tex]x^{2} + 2x = \frac{5}{4}[/tex]
Step 3: Divide 2 (from 2x) by 2 and square the result and add that to both sides of the equation.
2/2 = 1 1 squared = 1
[tex]x^{2} + 2x + 1 = \frac{5}{4} +1 = \frac{9}{4}[/tex]
Step 4: Factor the left side
[tex](x + 1)^{2} = \frac{9}{4}[/tex]
Step 5: Take the square root of both sides
x + 1 = ±[tex]\sqrt{\frac{9}{4} }[/tex] = ± [tex]\frac{3}{2}[/tex]
Step 6: Move the 1 to the right side and add the results
x = -1 ± [tex]\frac{3}{2}[/tex] = -1 + [tex]\frac{3}{2}[/tex] or -1 - [tex]\frac{3}{2}[/tex]
= [tex]\frac{1}{2}[/tex] or - [tex]\frac{5}{2}[/tex]
And bingo, you have the solutions by completing the square. Lot of fun, huh.
A box contains 315 half inch conduit couplings and weighs 119 pounds . An identical box also contains half-inch conduit couplings and weighs 47 pounds . How many coupling are in the second box ?
Answer: See explanation
Step-by-step explanation:
Let the coupling that are in the second box be represented by x.
We are informed that a box contains 315 half inch conduit couplings and weighs 119 pounds and that an identical box also contains half-inch conduit couplings and weighs 47 pounds. This can be represented in an equation as:
315/119 = x/47
Cross multiply
119 × x = 315 × 47
x = (315 × 47) / 119
x = 14805/119
x = 124.4
There are about 124 couplings in the box.
Can someone tell me which ones in first place and which ones in last place?
Find the class mark of the class 160- 165
Answer:
the classmark of the class is 162.5
Step-by-step explanation:
The computation of the class mark is shown below:
Given that
160 - 165
So, the class mark of the class is
= (Upper limit + lower limit) ÷ 2
= (160 + 165) ÷ 2
= 162.5
Hence, the classmark of the class is 162.5
please help me with this angle question :)
Answer:
its an acute angle
Step-by-step explanation:
its an acute angle be cause its small than a right angle
Answer:
angle AED = 70 degrees
angle x = 10 degrees
Step-by-step explanation:
since angle ABD = 110 degrees, major arc AED = 2(110) = 220 degrees
since angle ADB = 40 degrees, minor arc AB = 2(40) = 80 degrees
minor arc BD = 360 - 220 - 80 = 60 degrees
arc AB + arc BD = arc ABD
arc ABD = 80 + 60 = 140 degrees
angle AED = 1/2 (140) = 70 degrees
angle EAD = angle AED because isosceles
arc ED = 2(70) = 140 degrees
arc AE = arc AED - arc ED = 80 degrees
angle x = 1/2(arc AE - arc BD) = 1/2(80 -60) = 10 degrees
Evaluate: 4 + 13 - 2^2
Answer: 13
Step-by-step explanation:
According to pemdas (parenthesis, exponents, multiplication and divisions (from left to right)x aditioncand subtraction (left to right)
So first you would do 2^2 which 4
So now the equation would be 4+13-4
Positive 4 and negative 4 cancel out

The perimeter of a quadrilateral is 336.
The ratio of the sides is 2: 3: 2: 5. Find
the side lengths.
Just trying to win the CONTEST BUT GOOOOD LUCK
Answer:
56 units, 84 units, 56 units, 140 units
Step-by-step explanation:
Since you have the ratios, you can multiply each by x, because you do not know the actual values.
2x+3x+2x+5x=336
12x=336
÷12 ÷12
x=28
Then, plug in the values of x.
So 2*28= 56
3*28=84
2*28=56
5*28=140

Answer:
A
Step-by-step explanation:
We want to find the equation of the line in slope-intercept form.
From the graph, we are given the two points (-5, 1) and (0, -3).
We can find the slope between them. The slope formula is given by:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We will let (-5, 1) be (x₁, y₁) and (0, -3) be (x₂, y₂). Substitute:
[tex]\displaystyle m=\frac{(-3)-(1)}{(0)-(-5)}[/tex]
And evaluate:
[tex]\displaystyle m=\frac{-4}{5}=-\frac{4}{5}[/tex]
Next, notice that the point (0, -3) is already the y-intercept, so we do not need to find it.
Slope-intercept form is given by:
[tex]\displaystyle y=mx+b[/tex]
Therefore, our equation is:
[tex]\displaystyle y=-\frac{4}{5}x-3[/tex]
Our answer is A.
