10x^2+15x+5??? Rewrite the question by completing the square factor
Answer:
5 • (2x + 1) • (x + 1)
Step-by-step explanation:
Step 1 :
Equation at the end of step 1 :
((2•5x2) + 15x) + 5
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
10x2 + 15x + 5 = 5 • (2x2 + 3x + 1)
Trying to factor by splitting the middle term
3.2 Factoring 2x2 + 3x + 1
The first term is, 2x2 its coefficient is 2 .
The middle term is, +3x its coefficient is 3 .
The last term, "the constant", is +1
Step-1 : Multiply the coefficient of the first term by the constant 2 • 1 = 2
Step-2 : Find two factors of 2 whose sum equals the coefficient of the middle term, which is 3 .
-2 + -1 = -3
-1 + -2 = -3
1 + 2 = 3 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 1 and 2
2x2 + 1x + 2x + 1
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (2x+1)
Add up the last 2 terms, pulling out common factors :
1 • (2x+1)
Step-5 : Add up the four terms of step 4 :
(x+1) • (2x+1)
Which is the desired factorization
So the answer is:
5 • (2x + 1) • (x + 1)

Maya biked for 3 hours and then ran for 1 hour and 30 minutes. What distance did she cover?
PLZ HELP IN A BIG RUSH PLZ PLZ PLZ
Answer:
36 miles
Step-by-step explanation:
Maya can bike 9 miles in one hours, meaning that she can bike 27 miles in 3 hours. Since Maya can run 18 miles in 3 hours, and half of 3 is 1.5, she can run 9 miles in 1.5 hours.
Biking Miles + Running Miles= Total Miles
27 + 9= 36 total miles

∠a and ∠b are complementary angles. ∠a measures 24∘. What is the measure of ∠b?
Answer:
66°
Step-by-step explanation:
Complementary angles are those that add up to 90 degrees. Since a and b are complementary, we can write:
∠a + ∠b = 90
We already know that ∠a = 24°, so we can plug this in:
24 + ∠b = 90
∠b = 90 - 24 = 66°
Thus, the answer is 66°.
Find an ordered pair (x, y) that is a solution to the equation.
2x-y=7
Answer:
(0,−7)
Step-by-step explanation:
Since this is the equation of a straight line, there are no restrictions on what you could choose for a value of x. In "official" terms, we say the domain of the function is all real numbers.
Say you pick something simple like x=1. Now, insert this value, and the equation becomes
2−7=y
or y=−5
This means (1,−5) must be a point on the line, and it is also an ordered pair that satisfies the equation.

Answer:
I agree
Step-by-step explanation:
1>m just states that 1 is greater than the variable
m<1 States that the variable is less than 1
They both say that the variable is less than 1 so that basically mean they're the same

Answer: B. 140 cubic inches.
Step-by-step explanation:
The question is asking you to find the volume of the rectangular prism.
You can find this by using this formula:
[tex]V = w*h*l[/tex]
Where w is the width, h is the height, and l is the length.
Substitute the sides of the rectangular prism into the equation:
[tex]V = 3.5 * 10 * 4\\\\V = 140[/tex]
The volume of the prism is 140 cubic inches.
The correct answer is B.

A house is listed for sale at $235,000, but the listing does not include square
footage of the house. Based on the comps, the line of best fit is
y=0.06x + 60.5. If the price is fair, what size (in square feet) should the house
be?
A. 2850 ft^2
B. 2900 ft^2
C. 20,000 ft^2
D. 2350 ft^2
Answer:
Option B.
Step-by-step explanation:
If the cost of the house (y) is in thousands and area of the house is x ft².
Cost of the house is modeled by the equation given,
y = 0.06x + 60.5
By substituting the values in the line of best fit,
235 = 0.06x + 60.5
0.06x = 235 - 60.5
0.06x = 174.5
x = [tex]\frac{174.5}{0.06}[/tex]
x = 2908.33 ft²
x ≈ 2900 ft²
Therefore, Option B will be the correct answer.

If θ is an angle in standard position and its terminal side passes through the point (-9,-5), find the exact value of
cot
θ
cotθ in simplest radical form.
Answer:
Step-by-step explanation:9/5 is the answer
(-5)^2 + (-9)^2 =c^2
25 + 81 = c^2
106= c^2
Sqr rt 106 = c
By using trigonometric relations, we will see that:
cot(θ) = 9/5.
How to get the cotangent?We know that if an angle's terminal side passes through the point (x, y), then we can write the tangent as:
tan(θ) = y/x
In this case, we know that the terminal side passes through (-9, -5), then the tangent is:
tan(θ) = -5/-9 = 5/9
And the cotangent is the inverse of the tangent, then:
cot(θ) = 1/tan(θ) = 9/5.

Step-by-step explanation:
Take away the negative signs:
-80/-20
80/20
Now, divide normally.
80 ÷ 20 = 4
Since a negative number divided by another negative number is positive, the quotient is still 4.
Therefore, the simplified fraction is 4.

Hello hello!
Solving this is simple, just remember the vertical angles theorem. Due to this theorem, you are able to conclude that x+40 and 60 are equal in terms of their angle measure. This means that to solve this, we need to set both sides equal to each other and solve for x, and plug it in!
STEP ONE: 60 = x + 40
DO: Subtract 40 from both sides.
STEP TWO: 20 = x
DO: You've answered the question!

Answer:
C
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Gradient=
[tex] \frac{y1 - y2}{x1 - x2} [/tex]
[tex]m = \frac{ - 12 - ( - 15)}{ - 5 - ( - 1)} \\ m = \frac{15 - 12}{1 - 5} \\ m = - \frac{3}{4} [/tex]
y= -¾x +c
To find c, substitute a coordinate.
When x= -1, y= -15
[tex] - 15 = - \frac{3}{4} ( - 1) + c \\ c = - 15 - \frac{3}{4} \\ c = - 15\frac{3}{4} [/tex]
Thus the equation of the graph is
[tex]y = - \frac{3}{4} x - 15 \frac{3}{4} [/tex]
Therefore the answer is C.

The equation of the line in this graph is y = __x +___.
Answer:
The line equation is y = 1.5x + 3
Fill the first space with '1.5' and the second with '3'
Step-by-step explanation:
The generic model for a line equation is:
y = ax + b
To find the parameters 'a' and 'b', we can use two points of the graph in the equation.
Using the point (0, 3), we have:
3 = 0*a + b
b = 3
Using the point (-2, 0) and the value of b above, we have:
0 = -2*a + b
2a = 3
a = 1.5
So the line equation is y = 1.5x + 3

Aquarium one contains 4.6 gallons of water. Louise will begin filling aquarium one at a rate of 1.2 gallons per minute.
Aquarium two contains 54.6 gallons of water. Isaac will begin draining aquarium to at a rate of 0.8 gallons per minute.
After how many minutes will both aquariums contain the same amount of water?
Answer:
25
Step-by-step explanation:
4.6 + 1.2g = 54.6 -.8g
1.2g + .8g = 54.6 - 4.6
2g = 50
g = 25
Answer:
Hideki is draining a 45-gallon aquarium at a rate of 15 gallons per minute. Let's solve for the initial value of the linear function that represents thissituation. => 45 gallon aquarium at rate of 15 gallons per minute.

The volume of oblique cone, to the nearest tenth is,
⇒ 142.3 units³
What is the volume of an object?The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.
Since, WE know that,
Volume of oblique cone = (1/3) x π x r² x h
Given that,
Radius (r) = 4 units
Height (h) = 8.5 units
Thus:
Volume of oblique cone = (1/3) x π x 4² x 8.5
Volume of oblique cone = 1/3 × 3.14 × 16 × 8.5
Volume of oblique cone = 142.3 units³
