in a xy-coordinate system line 1 has a slope of -3. If the points (2,16 and (5,t) are on line 1, what is the value of t?

1 answer:

8 0

We can use the formula y2-y1/x2-x1 to find our answer. So, we have : t-16/5-2 = -3. We simplify that to t-16/3 = -3. We can then multiply both sides by 3 to get t-16 = -9. Then we can add 16 to both sides to get t = 7.

Using the order of operations, what are the steps for solving this expression? 40/8+3^2+(15-7)*2 Arrange the steps in the order

Answer:

simplify parentheses
evaluate the exponential term
divide 40/8
multiply 8*2
add 5+9
add 14+16

Step-by-step explanation:

40/8+3^2+(15-7)*2 . . . . given

The order of operations tells you to start by evaluating expressions in parentheses. Here, that is the subtraction of 7 from 15.

40/8 +3^2 +8*2 . . . . (15-7) = 8

Then you evaluate exponential terms.

40/8 +9 +8*2 . . . . . 3^2 = 9

Then perform multiplication and division, left to right. Here, division is first, then multiplication.

5 +9 +8*2 . . . . . divide 40/8 = 5

5 +9 +16 . . . . . . multiply 8*2 = 16

Finally, perform addition and subtraction, left to right.

14 +16 . . . . add 5+9

30 . . . . . . . add 14+16

Alexa spins a spinner that is divided into equally sized red, green, and blue sections. What is the probability that Alexa spins

vesna_86 [32]

The probability that Alexa spins an orange is zero. Since there is no orange on the spinner, there is no way for her to get an orange. Hope this helped!

Solve the equation. Check for extraneous solutions.<br><br> <img src="https://tex.z-dn.net/?f=2%7C7-7x%7C%3D2x%2B4%20" id="TexFo

lakkis [162]

2(7-7x) = 2x + 4
14 - 14x = 2x +4
16x = 10
x = 10/16
x = 0.625

2[-(7-7x)] = 2x + 4
-14 +14x = 2x + 4
12x = 18
x = 18/12
x = 1.5

answer:
solutions x = 0.625 and x = 1.5

Which equation represents the graphed function ?

goldenfox [79]

Answer:

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (1, 1)

m = $\frac{1-3}{1-0}$ = - 2

note the line crosses the y- axis at (0, 3) ⇒ c = 3

y = - 2x + 3 → A

What is 1 3/8 close to?

kozerog [31]

It depends what your trying to get close to. If your trying to get close to a number that is easier to work with 1 4/8 is good because its the same as 11/2 but the closest whole number is 1.
