Answer:

I think the answer is

$x = \frac{9}{7}$

Step-by-step explanation:

Reason :

$4x - 2 + 3x - 7 = 0 \\ collect \: like \: terms \\ 4x + 3x - 7 - 2 = 0 \\ 7x - 9 = 0 \\ 7x = 9 \\ x = \frac{9}{7}$

Therefore

$x = \frac{9}{7}$

Find the slope of the line through each pair of points.<br><br> (19, −2), (−11, 10)

Stels [109]

Answer:

slope = $-\frac{2}{5}$

Step-by-step explanation:

1) Calculate the slope using slope formula, $\frac{y_2-y_1}{x_2-x_1}$ . Use the two points given, substitute their x and y values into the formula, and solve.

$\frac{(10)-(-2)}{(-11)-(19)} \\= \frac{10+2}{-11-19} \\= \frac{12}{-30}\\= -\frac{2}{5}$

Thus, the slope is $-\frac{2}{5}$ .

Please help with algebra

Rudiy27

Sorry, mate but it cannot be solved. m is a complicated number like $\sqrt{-1}$

But if you really want the answer, here it is:
m = (5 ± 3 $\sqrt{-7}$ ) / 4

If it helps, can you give me the brainliest answer? I need it...

Thank you very much.

I need major help with #2 and #3. Those are main concerns. If #5 could be done as well I’d appreciate it. It’s on Circles

jekas [21]

Answer:

2. 40.83 or 13π

3. a) 6π/5

b)21.6π

Step-by-step explanation:

2. Use the proportion arc length over angle measure:

x/360 = 7.94/70

x = 360 * .113 = 40.83 or 13π in exact form

3. a) 24π/20 because circumference divided by the total number of slices which reduces to 6π/5

b) 360/20 = 18 degrees per slice, so 13 slices have an angle measure 234 degrees

Set up a proportion between the area of the full pizza over the angle measure and the area of the pizza (the unknown value being solved) and its angle measure

144π/360 = x/234

(234*144π)/360 = 21.6π
