Reduce to simplest form
Alina [70]

Answer:

-1 5/28

Step-by-step explanation:

-3/7 + (-3/4)

Get a common denominator of 28

-3/7 *4/4 = -12/28

-3/4 *7/7 = -21/28

-12/28 + -21/28

-33/28

-28/28 - 5/28

-1 5/28

A function g(x) has x-intercepts at (StartFraction 1 Over 2 EndFraction, 0) and (6, 0). Which could be g(x)? g(x) = 2(x + 1)(x +
Tcecarenko [31]

Answer:

g(x) = (x-6)(2x-1)

Step-by-step explanation:

g(x) intercepts the x-axis at these 2 points:

(6,0) ;(1/2,0)

⇒ 6 and 1/2 are roots ie; if you insert x=6 or x=1/2 into the equation of g(x) you will obtain a 0.

g(6) = g(1/2) = 0

now in order for 0 to appear we should have x-6

now in order for 0 to appear we should have x-1/2

but  x-1/2 doesn't appear in any of these, but its multiple of 2 is there:

2(x-1/2) = 2x-1

Therefore the function;

g(x) = (x-6)(2x-1)

If f(x) = 2x2 + 5x - 8 and f(x) = -10,<br> which of the following could be a<br> value for x?<br> -2
alexdok [17]

Answer:

x = -2 or x = -1/2

Step-by-step explanation:

We can just set up an equation where the quadratic is equal to -10, and then solve the equation:

2x^2+5x-8=-10\\2x^2+5x+2=0\\\\

Now, factor:

(2x+1)(x+2) = 0\\x=-2 \text{ or } x=-1/2

Drag the tiles to the correct boxes to complete the pears. Match the values based on parallelogram ABCD, shown in the figure.
faust18 [17]

Answer:

L$ength of \overline{BC} \rightarrow 4$ units\\Value of y\rightarrow44^\circ\\m\angle DAB\rightarrow56^\circ\\$Value of x \rightarrow 2$ units

Step-by-step explanation:

In parallelogram ABCD, BC=AD

Given:

BC=(6-x) units

AD =(x+2) units

Therefore:

6-x=x+2

x+x=6-2

2x=4

x=2

BC=(6-x) units

=(6-2) units

BC=4 units

The opposite angles of a parallelogram are equal. Therefore:

m\angle BCD=m\angle BAD\\12^\circ+y^\circ=100^\circ-y^\circ\\y^\circ+y^\circ=100^\circ-12^\circ\\2y^\circ=88^\circ\\y=44^\circ

m\angle DAB=100^\circ-y^\circ\\=100^\circ-44^\circ\\m\angle DAB=56^\circ

Therefore, the match is:

L$ength of \overline{BC} \rightarrow 4$ units\\Value of y\rightarrow44^\circ\\m\angle DAB\rightarrow56^\circ\\$Value of x \rightarrow 2$ units
