EFGH is translated 5 unite to the left and 2 units up.
What the coordinates of E'?
A. E' (6,-6)
B. E'(-1,1)
C. E'(-1,-3)
D. E' (9,-3)
Answer:
B. E'(-1,1)
Step-by-step explanation:
Change the X value of each of the points by -5, as this represents 5 units left.
Change the Y value of each of the points by +2, as this represents 2 units up.
For E:
X: 4 - 5 = -1
Y: -1 + 2 = 1
Coordinate: (-1,1)

Need help with this asap!
Step-by-step explanation:
step 1. m: m is the variable, 1 is the coefficient, 1 is the degree, constant is 0.
step 2. 3t^2 +4t - 6: t is the variable, 3 and 4 are the coefficients, 2 is the degree, -6 is the constant.
step 3. 2 - h: h is the variable, -1 is the coefficient, 1 is the degree (highest variable exponent), the constant is 2.
step 4. -7a^2: a is the variable, -7 is the coefficient (before the variable), 2 is the degree, the constant is 0.
each of equal sides of an isosceles triangle is 4cm greater than its height .If the base of triangle is 24 cm ,calculate the perimeter and the area of the triangle
192 cm²
Step by step explanation :-Let us take the height be x , then its side = x + 4. Now half of base will be 12 cm .
According to Pythagoras Theorem :-
=> base² + perpendicular ² = hypontenuse ²
=> 12² + x² = (x+4)²
=> 144 + x² = x² + 16 + 8x
=> 8x = 144-16
=> 8x = 128
=> x = 128/8
=> x = 16 cm .
Hence the height of ∆ is 16 cm .So the area will be half the product of base and altitude.
= 1/2 * 16 cm * 24cm .
= 192 cm²
★ Hence the area of the triangle is 192 cm² .Find the value of each variable round your answer to the nearest 10th
Answer:
10 for x and y
Step-by-step explanation:
Because the triangle adds up to 30 deggrees
So... you want to take 4 out.
30- 4 = 24
Than...You want to divided 24 by 2.
And that equals 12
Than round 12's by tenth
Which equals 10

which function has the steepest slope 2x-12 and y= 9- 3x
x+y =0
3x+y=16
x-y+4=8
will give brainliest if correct
Answer:
A
Step-by-step explanation:
For the function y = f(x), a reflection in the y axis is y= f(-x)
(-x)^3 = -x^3 so negate that term
(-x)^2 = x^2 so leave that as is
(-x)^1 = -x so negate that term too
Solve the equations 2x + 2 = x + 9
Answer:
x=7
Step-by-step explanation:
Answer:
x = 7
Step-by-step explanation:
Given
2x + 2 = x + 9 ( subtract x from both sides )
x + 2 = 9 ( subtract 2 from both sides )
x = 7
which equation would be the easiest to solve first by using the substitution method? EXPLAIN WHY
equation 1: 3x+5y= -8
equation 2: x- 2y=1
Answer:
Equation 2: x - 2y = 1
Step-by-step explanation:
The equations easiest to use substitution are the ones that have the variable multiplied by one, as in the case of Eq. 2 where x is 1x, so if you substitute a zero for x, we know that y has to be -1/2 for the equation to be true. Furthermore, if you substitute a 0 for y you automatically know that x = 1.
If you try to substitute anything for x in equation 1, let's say x = 1, you still have to multipy by 3, then the rest of the problem would be more steps.
f(x) = x2 – x + 11
g(x) = -x – 4
Find: (gof)(x)
Answer:
g(f(x)) = -x^2 + x - 15
Step-by-step explanation:
g(f(x^2 - x + 11) = -1 * (x^2 - x + 11) - 4 = -x^2 + x - 11 - 4 = -x^2 + x - 15

Answer:
x=72 degrees
Step-by-step explanation:
180-108=72
it is 180 because a straight angle is 180 degrees.
then you subtract 108, which is an alternate interior angle, to get 72, which is an alternate exterior angle.
Answer:
x=72
Step-by-step explanation:
Since the whole angle is 180 you have to do 180-108 which you get 72.
Then since x and 72 are vertical angles they have to be the same so x=72
