Step-by-step explanation:
a^2+b^2=c^2
12^2+5^2=c^2
144+25=c^2
169=c^2
c=13
Answer:
13
Step-by-step explanation:
I am a little rusty on this but I think to solve youd do
12^2 which is 144 plus 5^2 which is 25, add together and get 169 and then find that the square root of 169 is 13.

Describe the difference between slope and y-intercept
Answers
Answer:
The difference between slope and y-intercept, is y-intercept is a specific point. Y-intercept is when the line crosses the y-axis, or when x = 0. Slope is how much the y value changes when the x has changed +1, or -1, if that makes sense.

What is the equation of the line that passes through the point (-5, -2) and has a
slope of -6/5
Answers
Answer:
Step-by-step explanation:
you are given the slope m = -6/5 and one point (x1,y1) as (-5,-2)
next use the point-slope formula [y-y1 = m(x-x1) ] and plug in the point and the slope
y-(-2) = -6/5(x-(-2)) ( they are making this tuff with all the minus signs :/ )
y+2 = -6/5(x+2) ( nice looks better, distribute the -6/5 )
y + 2 = -6/5x -12/5 (move the 2 over )
y = -6/5x - 12/5 -2 ( 2 = 10/5 )
y = -6/5x -12/5 - 10/5 (add the fractions )
y = -6/5x -22/5
that's in the form of the slope-intercept now [ y = mx + b ] so you're done :)
What is the equation for the graph shown below?
A. x^2 – 3x – 25
B. x^2 – 7x – 25
C. x^2 + 7x – 21
D. x^2 + 2x - 25
Answers
9514 1404 393
Answer:
D. x^2 + 2x - 25
Step-by-step explanation:
The y-intercept is -25, eliminating choice C. The axis of symmetry is negative, eliminating choices A and B. (The axis of symmetry is x = -b/(2a), so the coefficient of x must be positive for a negative axis of symmetry.)
The only viable choice is D:
x^2 + 2x - 25
_____
Additional comment
Though the y-intercept is in the right place, it seems to me the vertex and x-intercepts are slightly too far left for the given equation. That is why I chose to eliminate non-viable answers, rather than try to determine the equation directly. That is also why I elected to show a better graph of equation D.

How many students attend the school? (Please also write the equation)
Answers
Answer:
254/2=127
127*3=381
381+1=382
Step-by-step explanation:
254/2 because 2/3 of the students is 254 and this is to simplify it
127*3 because 127 is 1/3 of the total number of students so 127*3 would be 3/3 of the students or all of them
381+1 because we had to take out 1 of the students because there was an aditional vote so we add him back in
The Answer Is: 382
Equation: (254/2)*3+1

Which graph has an x-intercept of -2 and a y-intercept of 4?
Answers
Answer:
The first graph
Step-by-step explanation:
the first graph crosses through -2 on the x-axis and 4 on the y-axis
The required graph that shows an x-intercept of -2 and a y-intercept of 4 is graph A. Option A is correct.
What is the intercept in the equation?In the equation intercept is the value of the linear function where either of the variables is zero.
Here,
X intercept is the value of the line where y ordinate is zero, from observation it is found that graph A has x intercept of -2 and y-intercept of 4.
Thus, the required graph that shows an x-intercept of -2 and a y-intercept of 4 is graph A. Option A is correct.

The missing angle U is 86°, the value that makes the total be 360°. Then the top two angles total 180°, as do the bottom two angles. This means sides SV and TU are parallel, but sides UV and ST are not.
The figure has one pair of parallel sides, so is a trapezoid.

We can see two main triangles from the image which are;
ΔVWX and ΔYZX
The two triangles are similar and using ratio of similar triangles, we have;
VW/WX = YZ/ZX
Plugging in the relevant values gives;
10/6 = YZ/3
Cross multiply to get;
YZ = 3 * 10/6
YZ = 5 miles
Since speed is given as 3.2 miles per hour and we know that formula for time is;
time = distance * speed
Then; time = 5 * 3.2
time = 16 hours

ABC congruent DEF find the measure of the given angles or the lengths of the given sides
Answers
Answer:
BC = 8 and EF = 8
Step-by-step explanation:
Congruent triangles have equal angles, equal sides, equal perimeters, and equal areas.
Let us solve the question
∵ The two triangles ABC and DEF are congruent
∴ BC = EF
∵ BC = 3z + 2
∵ EF = z + 6
→ Equate their length
∴ 3z + 2 = z + 6
→ Subtract z from both sides
∵ 3z - z + 2 = z - z + 6
∴ 2z + 2 = 6
→ Subtract 2 from both sides
∵ 2z + 2 - 2 = 6 - 2
∴ 2z = 4
→ Divide both sides by 2
∴ z = 2
→ Substitute z by 2 in the length of sides BC and EF to find them
∵ BC = 3(2) + 2 = 6 + 2
∴ BC = 8
∵ EF = 2 + 6
∴ EF = 8
