Find the values of < and y. (8x + 7) 5yº (7y -- 34) = (2x - 4)^

Lilit [14]

Answer:

x = 11

y = 17

Step-by-step explanation:

We know that opposite angles (or vertical angles) are equal.

8x + 7 = 9x - 4

Subtract 8x from both sides of the equation

8x - 8x + 7 = 9x - 8x - 4

7 = x - 4

Add 4 to both sides of the equation

7 + 4 = x - 4 + 4

11 = x

Looking at the other 2 angles,

5y = 7y - 34

Subtract 7 y from both sides of the equation

5y - 7y = 7y - 7y - 34

-2y = -34

Divide both sides by -2

-2y/-2 = -34/-2

y = 17

Find the following when a = -1, b = 2, c = -1/4 (4b - 3)/(2a) -1

Katena32 [7]

We substitute the given into the equation
given: a=-1, b=2, c= $\frac{-1}{4}$
=( $\frac{4b-3}{2a}$ -1
= $\frac{4(2)-3}{2(-1)}$ -1
= $\frac{8-3}{-2}$ -1
= $\frac{5}{-2}$ -1
to continue, we can either find a common denominator or change the fraction to decimal.
Fraction to Decimal:
$\frac{5}{-2}$ =-2.5
Equation=-2.5-1=-3.5
OR Common Denominator:
= $\frac{5}{-2}$ $\frac{-1}{1}$ × $\frac{-2}{-2}$ (denominator should be -2=common)
= $\frac{5}{-2}$ + $\frac{2}{-2}$
= $\frac{7}{-2}$
which also = to -3.5

Determine the equation of the graph and select the correct answer (-4,-1)

Snowcat [4.5K]

Answer:

(-4,-1)

Step-by-step explanation:

Assuming the graph is the one shown in the attachment.

The forward sloping line has a slope of 1 and a y-intercept of 3.

The equation of this line is y=x+3

The horizontal line has a slope of 0 and y-intercept of -1.

It's equation is y=-1

The two lines intersect at (-4,-1)

At the age of 22, Vicki opened an IRA. At the beginning of each year, she deposits $1100 into her IRA, which earns 9% annual int

jeyben [28]

Answer:

$51,557.00

Step-by-step explanation:

1100 times 9% = 99 a year

99 times 43 = 4257

1100 times 43 =47,300

then you add 47,300 + 4257 = 51,557

you take your total that she put into the ira and multiply it by 9%

then you multiply that total by the number of years before she retires which is 43

so 99 times 43 = 4257

then you will multiply how much she put in the ira at the beginning of the year which is 1100 by the 43 years before she retires which is 47,300

then you add your totals together

4257 + 47,300 = 51,557
