Answer:
5x+6
Step-by-step explanation:
(1/3*9x)+(1/3*16)+(1/3*2)+2x=
3x+16/3+2/3+2x=
5x+18/3=
5x+6
Answer:
the above photo is what you should do. multiply every term with every other term in each bracket.
Answer:
Lower left.
Step-by-step explanation:
To determine if a graph is a function the "vertical line test is used. If any point on a graph has one x value go to two y values it is not a function.
Witht he four pictures, the two on the right use a horizontal line, so it doesn't tell at all, on the leftthe upper one is vertical but it doesn't show that one x value has two corresponding y values. So it must be the lower left one.
The lower left picture has a line at x=1, and it passes through the line of the graph at two different y values, 4 and -4. So this has two y values with one x value.
Answer:
Final cost = $3070.90
Step-by-step explanation:
First we need to find the discount
Discount = original price * percent off
Discount = 2200 * .15
Discount = 330
Sale price = original price - discount
Sale price = 3200-330
Sale price = 2870
Now we need to calculate tax
Tax = sales price times tax rate
Tax = 2870 * .07
= 200.90
Final price = sales price plus tax
Final price = 2870 + 200.90
3070.90
The squares are shown in the attached picture.
As you can see, JC is half the diagonal of ABCD and JH is half the diagonal of EFGH.
In order to find the area of the shaded figure, we need to subtract the area of the white square (EFGH) from the area of the big square (ABCD).
The area of a square know the diagonal is given by the formula:
A = d² ÷ 2
A(ABCD) = (2×JC)² ÷ 2
= (2×9)² ÷ 2
= 162 cm²
A(EFGH) = (2×JH)² ÷ 2
= (2×4)² ÷ 2
= 32 cm²
Therefore:
A = A(ABCD) - <span>A(EFGH)
= 162 - 32
= 130 cm</span>²
The area of the shaded region is
130 cm².
