Answer:
Step-by-step explanation:
Let the consecutive integers be x - 1 , x , x + 1
Equation
2*(x - 1 + x) = 3*(x+1) - 2
Solution
2(2x - 1) = 3(x + 1) - 2 After the first two have been combined remove the brackets.
4x - 2 = 3x + 3 - 2 Combine the right
4x - 2 = 3x + 1
4x - 2 + 2 = 3x + 1 + 2 Add 2 to both sides
4x = 3x + 3 Subtract 3x from both sides
4x-3x = 3x - 3x + 3 Combine
x = 3
Check
Left hand side
2(2 + 3)
2(5)
10
Right hand side
3*(x+1) - 2
3*(4) - 2
12 - 2

Jodi owes $38,000 in students loans for college. The interest rate is 7.25% and the loan will be paid off over 10 years. How much will Jodi pay TOTAL?
Answer:
Jodi will have to pay $38,000 in principal plus $27,550 in interest for a total of $65,550.00.
Step-by-step explanation:
Solution:
P = $38,000, R = 7.25% and T = 10
I = P*R*T
I = (38000)*(.0725)*(10) = $27,550.00
Answer: Jodi will have to pay $38,000 in principal plus $27,550 in interest for a total of $65,550.00.
Answer: Jodi will pay $65,550.00 in total.
Steps: 7.25% of $38,000 is $2,755.00
Multiply 2,755.00 times 10: 2,755 × 10 = 27,550
$38,000.00 + $27,550.00 = $65,550.00

Help please ? What’s the inequality?
9514 1404 393
Answer:
-1 < x < 5
Step-by-step explanation:
The open circle at -1 and the shading to its right tells you ...
-1 < x
The open circle at 5 and the shading to its left tells you ...
x < 5
Both of these are true together, so the compound inequality representing that is ...
-1 < x < 5
_____
Additional comments
If the circle were filled, the relation would include the "or equal to" case: ≤.
I like to use the "left-pointing" relation symbols (<, ≤) because they put the numbers and variables in the same relationship they are on the number line. That is, -1 is on the left end of the shaded segment; the shading (variable value) is in the middle, and 5 is on the right end--the same as ...
-1 < x < 5
At noon, a tank contained 8 in. of water. After several hours, it contained 2 in. of water. What is the
percent decrease of water in the tank?
Answer:
75%
Step-by-step explanation:
To find the percent decrease, use the percent change formula:
(difference / original) x 100
8 - 2 = 6, so the difference is 6.
Plug in the difference and original:
(6 / 8) x 100
= 75
So, the percent decrease is 75%

ΔABC is dilated using a scale factor of 12 to produce ΔA'B'C'. Select all of the statements that apply to the transformation.
Answer:
Options (3) and (6)
Step-by-step explanation:
ΔABC is a dilated using a scale factor of [tex]\frac{1}{2}[/tex] to produce image triangle ΔA'B'C'.
Since, dilation is a rigid transformation,
Angles of both the triangles will be unchanged or congruent.
m∠A = m∠A' and m∠B = m∠B'
Since, sides of ΔA'B'C' = [tex]\frac{1}{2}[/tex] of the sides of ΔABC
Area of ΔA'B'C' = [tex]\frac{1}{2}(\text{Area of triangle ABC})[/tex]
Area of ΔABC > Area of ΔA'B'C'
Since, angles of ΔABC and ΔA'B'C' are congruent, both the triangles will be similar.
ΔABC ~ ΔA'B'C'
Therefore, Option (3) and Option (6) are the correct options.
Answer: The Third option and the sixth option.

Help with trigonometry homework
By definition of tangent,
tan(A - π/4) = sin(A - π/4) / cos(A - π/4)
Expand the numerator and denominator using the angle sum identities for sin and cos:
tan(A - π/4) = (sin(A) cos(π/4) - cos(A) sin(π/4)) / (cos(A) cos(π/4) + sin(A) sin(π/4))
Divide through everything on the right by cos(A) cos(π/4):
tan(A - π/4) = (sin(A) / cos(A) - sin(π/4) / cos(π/4)) / (1 + (sin(A) sin(π/4)) / (cos(A) cos(π/4)))
Simplify the sin/cos terms to tan:
tan(A - π/4) = (tan(A) - tan(π/4)) / (1 + tan(A) tan(π/4))
tan(π/4) = 1, so we're left with
tan(A - π/4) = (tan(A) - 1) / (1 + tan(A))
Replace tan(A) with -√15:
tan(A - π/4) = (-√15 - 1) / (1 - √15)
Then the last option is the correct one.

Which relation is a function?
a.
{(5,3), (2,8), (-5, -1),(4,7), (2, 1)}
b. {(5,3), (2,8), (-5,-1), (4,7), (-2, 1)}
{(5,3), (2,8), (-5, -1), (4,7), (5,7)}
d. {(-5,3), (2,8), (-5, -1), (4,7), (
2, 2)}
Answer: b
Step-by-step explanation:
You can determine which is a function by looking at the x values. If an x value repeats, it is not a function. In A, the x variable 2 repeats so it is not a function. In C, the x variable 5 repeats. In D, the x variable -5 repeats. The only answer choice where none of the x values are the same is B, so the answer is B. Hope this helps!

what is the volume
Answer:
The volume is 227.5
Step-by-step explanation:
The volume for a triangular prism, such as this is, (lxwxh)/2. Because in all shapes volume equals the area multiplied by the height or depth. And an area of a triangle is l or base multiplied by the altitude or w, divided by 2. So the area would be 5x7/2, 35/2, 17.5. And the volume would be 17.5x13, 227.5

i will give lots of points and brainly please help asap What is the equation of the quadratic of the quadratic graph with a focus of (1,3) and a directex of y= 1 show your work please
check the picture below.
now, we know the directrix is at y = 1, and the focus point is at 1,3, well, notice the picture, the distance between those fellows is just 2 units.
the vertex is half-way between those fellows, therefore, the vertex will be at 1,2.
the distance "p", from the vertex to either the directrix or focus, is really just 1 unit. Since the focus point is above the directrix, is a vertical parabola, and it opens upwards, like in the picture, and since it opens up, the "p" value is positive, or +1.
