Answer:
72.7
Step-by-step explanation:
complementary angles: either of two angles whose sum is 90°.
90-17.3 = 72.7
Answer:
Complementary angle of 17.3° is (90°-17.3°)=72.7°
72.7° is the right answer.3х + 4y = - 23
х = 3y+1
Solve systems of equations!
Answer:
[tex]3(3y + 1) + 4y = - 23 \\ 9y + 3 + 4y = - 23 \\ 9y + 4y = - 23 - 3 \\ \frac{13y}{13y} = \frac{ - 26}{13} = - 2[/tex]
Hari's weekly allowance varies depending on the number of chores he does. He received $20 in allowance the week he did 10 chores, and $16 in allowance the week he did 2 chores. Write an equation for his allowance in slope-intercept form.
Answer:
y=1/2x+12
Step-by-step explanation:
Answer:
y = 2x + (-30)
Step-by-step explanation:
Find the slope, then find the y-intercept.
But that is for if the points are, (20,10) and (16,2)
If you were finding the equation for the points, (10,20) and (2,16) the equation would be y = 0.5x + 15

Identify the a,h,k and vertex for each quadratic function
9514 1404 393
Answer:
a = -2, h = -3, k = -1
vertex = (-3, -1)
Step-by-step explanation:
Compare the given equation ...
g(x) = -2(x +3)² -1
to the vertex form ...
g(x) = a(x -h)² +k
You see that ...
a = -2
-h = +3 ⇒ h = -3
+k = -1 ⇒ k = -1
The vertex is (h, k), so is ...
vertex = (-3, -1)
Kathy jumped 16 1/2 ft at the long jump event. Nadia jumped 18 1/8 ft at the long jump. How much farther did Nadia jump than Kathy?
Answer:
12 ft
Step-by-step explanation:
First you do 16 x 2 +1 and you get 133, second you do 18 x 8 +1 = 145 third you need to subtract 145 - 133, and you get 12 feet.

3,1,-2,-4,-1, least to greatest
Answer:
-4, -2, -1, 1, 3
Step-by-step explanation:
Because some of these numbers are negative, they will be getting smaller as they get bigger. Think of it like this:
When you are determining whether the negative number is bigger or smaller, take the negative sign off or pretend its not there. Then, as the numbers get bigger, they become less. For example, you have these numbers:
-1, -5, -8, -3, and -2
To find out what the order is from least to greatest, you do this:
take the negative sign off
1,5,8,3, and 2
then put them in order from least to greatest
so its
1, 2, 3, 5, 8
Then flip it so its from greatest to least
so its
8,5,3,2,1
Now put the negative signs back
making it:
-8, -5, -3, -2, and -1
That is how you find out what the numbers are from least to greatest.
Hope this helps!

Answer:
m∠J = 85°
Step-by-step explanation:
Angles G and H are congruent to angles Q and R, respectively. The sum of angles in a quadrilateral is 360°, so we have ...
∠J +∠F +∠G +∠H = 360°
∠J +109° +122° +44° = 360°
∠J = 360° -275°
m∠J = 85°
Solve the given equation for y. Enter DNE if there is no solution. Enter R if all numbers are the solution. 7y+5=6y+1.
How would I solve this?
Answer:
I think the answer is Y= -4. I'm not really sure what you are asking for though.
Step-by-step explanation:
7y + 5= 6y + 1
7y = 6y - 4
y = -4

How come two negatives make a positive, but three negatives makes a negative? Does this have to do with there being an odd/even amounts of negatives and cancelling each other out?
Okay well work step by step. If there is three negatives, you first want to multiply the first two negatives. Your number will come out positive but you are still left with one more negative. so you will multiply the positive number with the negative number which comes out with a negative number.

Answer:
2
Step-by-step explanation:
(x)(y) = k Inverse relationship
(4)(3) = k
12 = k
(6)(y) = 12
y = 2
Answer:
When y=3, x=4 but when x=6, y is :---
[tex] \frac{3}{4} = \frac{y}{6} \\ y = \frac{3 \times 6}{4} \\ y = \frac{9}{2} \\ \boxed{ y = 4.5}[/tex]

Answer:
The slope of the line = m = 3
Step-by-step explanation:
Given the table
x 3 6 8 12
y 7 16 22 34
Taking any two points let say (3, 7) and (6, 16)
(x₁, y₁) = (3, 7) (x₂, y₂) = (6, 16)Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [16 - 7] / [6 - 3]
= 9 / 3
= 3
Therefore, the slope of the line = m = 3
