Answer 1

Answer:

f(2) = -2

Step-by-step explanation:

plug in 2 to wherever x is in this statement:

f(2) = -2(2^2) - 2(2) + 10

f(2) = -2(4) - 4 + 10

f(2) = -8 - 4 + 10

f(2) = -2

Answer 2
f(2)= -2x^2 -2x +10
-2(4) -2(2) +10
-8 -4 +10
=-2

Answers

Answer:

36/40 or 90%

Step-by-step explanation:

First convert it to a fraction, which in this case is 36/40.

To find the percentage, we need to find an equivalent fraction with the denominator of 100. Multiply both numerator & denominator by 100.

36/40 × 100/100

= (36 × 100/40) × 1/100 = 90/100

Therefore, the answer is 90%.

If you are using a calculator, simply enter 36÷40×100, which will give you 90 as the percentage.

How many square yards of carpet are needed to cover the floor of a related 15 feet long and 12 feet wide

Answers

Answer:

20 yards squared.

Step-by-step explanation:

First, you should convert your units. Three feet make a yard, so 15 feet = 5 yards and 12 feet = 4 yards.

The area of a square is found by multiplying the length and width, so 5 yards x 4 yards = 20 yards.

A line passes through the point (4, - 7) and has a slope of
--
4
Write an equation in slope-intercept form for this line.

Answers

Answer: y = 4x-23

Step-by-step explanation:  I'm assuming the question asks:  "A line passes through the point (4, - 7) and has a slope of 4."  I had difficulty understanding the format of the question.  Slope intercept form is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).

We can start with y = 4x + b, since we are given the slope.  We can then use the given point (4,-7) to find b, since this point is on the line and thus satisfies the equation.

y = 4x + b

-7 = 4(4) + b

-7 = 16 + b

b = - 23

The equation is y = 4x-23

One angle of an isosceles triangle is known to be 68°. What would be one of the other angles?
a 44°
b 55°
c 66°
d 112°

Answers

Answer:

44

Step-by-step explanation:

Isosceles triangles have two angles that are equal.  If the two equal angles are 68

We have  68, 68, and an unknown angle x

They add to 180

68+68+x = 180

136+x=180

x =180-136

x =44

A student writes the equation for a line that has a slope of -6 and passes through the point (2, –8).

y -(-8) = -6(x - 2)

y -(-8) = -6x + 12

y -(-8) + 8 = -6x + 12 + 8

y = -6x + 20

Explain why the work is not correct.

Answers

Answer:

The student should subtract 8 from each side not add 8

Step-by-step explanation:

Point slope form is

y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line

y - -8 = -6(x -2)

y+8 = -6(x-2)

Distribute

y+8 = -6x+12

Subtract 8 from each side

y+8-8 = -6x+12-8

y = -6x+4

The student should subtract 8 from each side not add 8

Answer:

y -(-8) = -6(x - 2)

y -(-8) = -6x + 12

y -(-8) + 8 = -6x + 12 + 8 (this step is incorrect as minus into minus is plus therefore when taking 8 to the right hand side we must subtract it from the left hand side

y = -6x + 20

the correct equation would be : y= -6x+4
