Which measurements could not represent the side lengths of a right triangle?
A 6 cm, 8 cm, 10 cm
B 12 cm, 35 cm, 37 cm
C 4 cm, 6 cm, 10 cm
D 10 cm, 24 cm, 26 cm
6,8,10
Answer:
C
Step-by-step explanation:
It says COULD NOT so you just compare them. 10+4=14 so thats one side
6+10=16 so another side BUT 6+4=10 so that automatically cancels out the last side because it is equal to 10. It has to be above 10. So C is te correct answer.

Write an equation for the line that has a rate of change of 2 and passes through the point (-1, -5).
Answer:
An equation for the line that has a rate of change of 2 and passes through the point (-1, -5) will be:
[tex]y=2x-3[/tex]Step-by-step explanation:
As the equation for the line in the point-slop form is given by
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope (rate of change).
As we know that when we talk about 'slope', it means we are talking about 'rate of change'.Now given the values
Rate of change = slope = m = 2point (-1, -5)substituting the values m = 2 and the point (-1, -5)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-\left(-5\right)=2\left(x-\left(-1\right)\right)[/tex]
[tex]y+5=2\left(x+1\right)[/tex]
[tex]y+5-5=2\left(x+1\right)-5[/tex]
[tex]y=2x-3[/tex]
Therefore, an equation for the line that has a rate of change of 2 and passes through the point (-1, -5) will be:
[tex]y=2x-3[/tex]The equation of the line that passes through (-1, -5) and has a slope of 2 is;
[tex]\mathbf{y + 5 = 2(x + 1)}[/tex] (point-slope form)or
[tex]\mathbf{y = 2x - 3}[/tex] (slope-intercept form)Recall:
Equation of a line can be written either in the slope-intercept form as y = mx + c, or in point-slope form as y - b = m(x - a).m = slope; c = y-interceptRate of change = slopeGiven:
Slope (m) of the line is 2
Point on the line is (-1, -5)
Write the equation in point-slope form by substituting m = 2, and (a, b) = (-1, -5) into y - b = m(x - a).
Thus:
[tex]y - (-5) = 2(x - (-1))\\\\\mathbf{y + 5 = 2(x + 1)}[/tex]
Rewrite in slope-intercept form
[tex]y + 5 = 2x + 2\\\\y = 2x + 2 - 5\\\\\mathbf{y = 2x -3}[/tex]
Therefore, the equation of the line that passes through (-1, -5) and has a slope of 2 is;
[tex]\mathbf{y + 5 = 2(x + 1)}[/tex] (point-slope form)or
[tex]\mathbf{y = 2x - 3}[/tex] (slope-intercept form)Learn more here:

Horizontal and parallel lines e and f are cut by transversal b. At the intersection of lines b and e, the uppercase right angle is (2 x + 18) degrees. At the intersection of lines b and f, the top right angle is (4 x minus 14) degrees and the bottom right angle is y degrees. What is the value of y? 16 50 130 164
Answer:
130
Step-by-step explanation:
From the FIQURE of the question, we can see that line "e" is parallel to line "f" then we can say (2x + 18)=( 4x - 14)
Then we can collect like terms
2x-4x= -14-18
-2x=-32
The negatives cancelled out we have
x = 16
From the question, At the intersection of lines b and f, the top right angle is (4 x minus 14) degrees
Angle on a straight line is 180° then we can calculate "y" as
y = 180 - (4x - 14)
= 180-4x+14
= 180+14-4x
But x= 16, then substitute we have
= 180 +14 - 14(16)
= 130
Hence, the value of y is 130

4/5 w+13=25 please show work
Answer:
w=15
Step-by-step explanation:
4/5*w+13-(25)=0
STEP 1
4
Simplify —
5
Equation at the end of step1
4
((— • w) + 13) - 25 = 0
5
2.1 Adding a whole to a fraction
Rewrite the whole as a fraction using 5 as the denominator :
13 13 • 5
13 = —— = ——————
1 5
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
4w + 13 • 5 4w + 65
——————————— = ———————
5 5
Equation at the end of step2
(4w + 65)
————————— - 25 = 0
5
STEP 3
Rewriting the whole as an Equivalent Fraction :
3.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 5 as the denominator :
25 25 • 5
25 = —— = ——————
1 5
Adding fractions that have a common denominator :
3.2 Adding up the two equivalent fractions
(4w+65) - (25 • 5) 4w - 60
—————————————————— = ———————
5 5
STEP4
Pulling out like terms :
4.1 Pull out like factors :
4w - 60 = 4 • (w - 15)
Equation at the end of step
4 • (w - 15)
———————————— = 0
5
STEP 5
When a fraction equals zero :
5.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
4•(w-15)
———————— • 5 = 0 • 5
5
Now, on the left hand side, the 5 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
4 • (w-15) = 0
Equations which are never true:
5.2 Solve : 4 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
5.3 Solve : w-15 = 0
Add 15 to both sides of the equation :
w = 15
