Answer:
[tex] - \frac{5}{2} [/tex]
Step-by-step explanation:
4x -10y= 40
Let's rewrite this equation in the slope-intercept form (y= mx +c) so that we can obtain it's slope.
10y= 4x -40
Divide both side by 10:
[tex]y = \frac{2}{5} x - 4[/tex]
The product of the gradients of perpendicular lines is -1.
⅖(gradient of line)= -1
Gradient of perpendicular line
[tex] = - 1 \div \frac{2}{5} [/tex]
[tex] = - 1 \times \frac{5}{2} [/tex]
[tex] = - \frac{5}{2} [/tex]

The length of a rectangle is 1 foot more than twice the width. The area is 55 square feet. Find the length of the dimension of the rectangle.
Answer:
11 ft
Step-by-step explanation:
The formula for the area of a rectangle of length L and width W is
A = L * W.
Represent the length, L, by 2W + 1 ("1 more than twice the width"). Then the area formula (above) becomes:
A = 55 ft^2 = (2W + 1)(W), which, when simplified, results in:
2W^2 + W - 55 = 0, whose coefficients are {2, 1, -55}. Let's use the quadratic formula to solve this for W:
The discriminant, b^2 - 4ac, is 1^2 - 4(2)(-55), or 441. The square root of 441 is 21. Thus, the quadratic formula gives us:
-1 ± 21
W = ------------- = (1/4)(-1 + 21), or W = 5 and W = -22/4 = -11/2
2(2)
A measure of length can't be negative, so we reject W = -11/2 in favor of W = 5.
Then, according to the formula for L that we found earlier, L = 2W + 1, or
L = 2(5) + 1, or L = 11.
Check: Does L * W result in an area of 55 ft²? Yes
The length dimension of the rectangle is 11 ft

simplify 3a x 2b x 2
Answer:
[tex]12ab[/tex]
Step-by-step explanation:
3a × 2b = 6ab
6ab × 2 = 12ab
Therefor, the answer is 12ab.
3a × 2b × 2 = 12ab
The expression expects us to find the product . Therefore,
3a × 2b × 2Let's do it step by step
3a × 2b = 6ab
Then,
6ab × 2 = 12ab
Therefore,
3a × 2b × 2 = 12ab

what is the slope of 2x-4y=5
Answer:
1/2 or .5
Step-by-step explanation:
Hey There!
So the first step of this problem is to get y on one side and everything else on the other side
to do so we use inverse operations
so to get rid of the 2x we subtract 2x from each side
we would end up with -4y=5-2x
now want to get rid of the -4 on the y
to do so we would divide each side by -4
we would end up with
[tex]y=\frac{1}{2}x -\frac{4}{5}[/tex]
so we can conclude that the slope is 1/2 or .5
Triangle congruence and similarly (picture included) SAS, ASA, SSS, or AAS?
Answer:
SAS
Step-by-step explanation:
SAS Postulate: "If two sets of corresponding sides on two triangles and there included angle are congruent, then the triangles are similar".
We see that line segments XY-ST and XZ-SR are congruent along with the included angles X and S. Therefore, we can justify that SAS fits the situation.

This month a band has 6 musicians. This is a 50% increase from the number of
musicians in the band last month. How many musicians were in the band last month?
Answer:
4
Step-by-step explanation:
okay since there was a 50% INCREASE, 6 is (100%+50%) greater than last months amount.
100%+50%=150%=1.5
let's say that x is last months amount
6=1.5x
x=6/1.5
x=4
There were 4 musicians in the band last month.

Answer:
g(n) = 18 - 4n
Step-by-step explanation:
Given the recursive formula
g(n) = g(n - 1) - 4 with common difference d = - 4 and g(1) = 14
The explicit formula for an arithmetic sequence is
g(n) = g(1) + (n - 1)d , then
g(n) = 14 - 4(n - 1)
= 14 - 4n + 4
= 18 - 4n

Of 42 cities, 5 have a lake and 29 have a river running through them what fraction of these 42 cities have a lake or river running through them
Answer: 17/21
Step-by-step explanation:
Number of cities = 42
Fraction of cities that has lake = 5/42
Fraction of cities that have rivers = 29/42
The fraction of these 42 cities that have a lake or river running through them will then be:
= 5/42 + 29/42
= 34/42
= 17/21

Solve for x. 6x-20 4x+50
Answer: Simplifying
4x + 50 = 6x + 20
Reorder the terms:
50 + 4x = 6x + 20
Reorder the terms:
50 + 4x = 20 + 6x
Solving
50 + 4x = 20 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
50 + 4x + -6x = 20 + 6x + -6x
Combine like terms: 4x + -6x = -2x
50 + -2x = 20 + 6x + -6x
Combine like terms: 6x + -6x = 0
50 + -2x = 20 + 0
50 + -2x = 20
Add '-50' to each side of the equation.
50 + -50 + -2x = 20 + -50
Combine like terms: 50 + -50 = 0
0 + -2x = 20 + -50
-2x = 20 + -50
Combine like terms: 20 + -50 = -30
-2x = -30
Divide each side by '-2'.
x = 15
Simplifying
x = 15
A triangle has one angle that measures 61 degrees, one angle that measures 44 degrees, and one angle that measures 75 degrees. what kind of triangle is it?
choices
1.right triangle
2.obtuse triangle
3.acute triangle
Answer:
Acute triangle
Step-by-step explanation:
All the three angles of the triangle is less than 90, all angles are acute. So, it is acute triangle.
If any one of the three angles is 90, then it is right triangle.
If any one of the three angle is more than 90, then it is obtuse triangle.
