Answer:
Step-by-step explanation:
-29 +14 =-15
The biggest number "29" has minus "-" in front, so in the final the sigh will be minus. The final sigh on the answer dibents on the biggest number.
If you have this exercise :
-14 +29 =15
The biggest number has "+" in front of it

Select the two binomials that are factors of
81x2 - 36
0 9x - 6
9x + 12
9x + 6
9x - 3
Factors are 9x-6 and 9x+6
=================================================
Explanation:
We use the difference of squares rule
m^2 - n^2 = (m-n)(m+n)
In this case we have
m = 9xn = 6So,
m^2 - n^2 = (m-n)(m+n)
(9x)^2 - 6^2 = (9x-6)(9x+6)
81x^2 - 36 = (9x-6)(9x+6)
Answer:
9x + 6 and 9x -- 6
Step-by-step explanation:
81x2--36 = (9x) 2 -- (6)2 = a2 -- b2 = (a+ b )(a--b) = (9x+6)(9x-6)

Which describes the graph of y = (x - 4)2 - 1?
-
A. Opens up with a vertex at (4,-1)
B. Opens down with a vertex at (4,-1)
C. Opens up with a vertex at (-4,-1)
D. Opens down with a vertex at (-4,-1)
C opens up with a vertex at (-4,-1)
Answer:
A
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
y = (x - 4)² - 1 ← is in vertex form
with vertex = (h, k ) = (4, - 1 )
• If a > 0 then the graph opens up
• If a < 0 then the graph opens down
Here a = 1 > 0 then graph opens up
Thus option A

Answer:
B, or -75
Step-by-step explanation:
f(x) is a function of x.
If f(x) = 50 when x = -10, you can rearrange this information.
f(-10) = 50
f = -5
If f = -5...
-5 ( 15) = -75

Write a fraction setting the vertical length of the smaller triangle and the bigger triangle over its horizontal length. What do these fraction represent?
To see if the slopes are the same, write an equation setting the two fractions equal to each other. Is this equation true? Why or why not? What does that mean about the slope between points E and A and the slope between the points A and C?
Step-by-step explanation:
Vertical length of the smaller triangle is:
2 - 0 = 2Horizontal length of the smaller triangle is:
3 - 0 = 3The fraction:
2/3This fraction is same for the larger triangle, which is 4/6 = 2/3.
It means the slopes are same.
Since the slopes are same, the segments are part of same red line.
What is the relationship between Ingles 9 and 17
corresponding angles, Alternate exterior angles, constructive interior angles, or vertical angles
Answer:
alternative anglesmmmmnnyrrrt
Please help with this question I will give points
Answer:
46.8
Step-by-step explanation:
The missing angle in ∆PQR is 180° -76° -41° = 63°. Two angles are the same between the triangles, so we know they are similar. Side lengths of similar triangles are proportional.
Corresponding sides of the triangles are ...
ST ⇔ PQ ratio ST/PQ = 16.8/14 = 1.2
TU ⇔ QR ratio TU/QR = x/10 = 1.2 ⇔ x = 12
US ⇔ RP ratio US/RP = 18/15 = 1.2
The perimeter of ∆STU is the sum of its side lengths ...
16.8 +12 +18 = 46.8 . . . units
_____
Additional comment
The perimeter of PQR is 14 +10 +15 = 39. The scale factor applies to the perimeter, just as it does to the side lengths.
The perimeter of STU is 1.2×39 = 46.8.
ALL MY QUESTIONS GETTING IGNORED PLS HELP
Triangle XYZ is a scale drawing of triangle ABC.
What is the value of x?
Answer:
x=9
Step-by-step explanation:
a scale drawing means all the sides are multiplied by the same amount. to find this amount, you can divide the larger side by the bigger side by the smaller side.
15/5 = 3
12/4 = 3
therefore the scale factor is 3. to get the value of x, multiply the value of the third side by 3.
3*3=9
x=9

Steve set up a business making friendship bracelets. He earned $70 in January. He is projected to earn 120% more in February. How much is Steve projected to make in February? PLS HELP!
$84
$98
$154
$190
Answer:
its 84 dollars sorry I'm late
Step-by-step explanation: Make a proportional relationship.
make 120% into a fraction. 120/100
then make 70 into a fraction using a variable. For example, x/70
Then cross multiply 120 and 70. 120x70=8,400
Last divide 8,400 by 100 and that equals $84.

Estimate 11.92 x 3.21
11.92 × 3.21 = 38.2632
Answer:
-If you need to round to the whole number, you would round down to 38
-If your answer needs to be a decimal, it would be 38.30
If you don't have a specific way you need to round it, estimates are usually whole numbers, so your answer would be 38

2 factors that add to 6 but multiply to 60
Answer:
The short answer is there isn’t.
Start by writing each of these as an expression:
x * y = 60
x + y = 7
Next, solve each for the same variable; in this case, y:
(x * y) / x = 60 / x
.: y = 60 / x
(x + y) - x = 7 - x
.: y = 7 - x
Next, replace y of the second expression to the first
y = 60 / x & y = 7 - x
.: 7 - x = 60 / x
Now, solve for x:
(7 - x) * x = (60 / x) * x
.: x * 7 - x^2 = 60
This is quadratic, so write it in the form of ax2 + bx + x = 0
(-1)x^2 + (7)x + (-60) = 0
.: a = -1, b = 7, c = -60
Finally solve for b:
x = (-b +- sqrt(b^2 - 4*a*c)) / 2a
.: x = (-7 +- sqrt(7^2 - 4*-1*-60)) / (2 * -1)
.: x = (-7 +- sqrt(49 - 240)) / -2
.: x = (-7 +- sqrt(-191)) / -2
The square root of a negative value is imaginary and thus there’s no real answer to this problem.
