Answer:

The equation is linear

Step-by-step explanation:

You can determine the type of equation based on the degree of the equation.

The degree is the value of the greatest exponent for a term. (Terms are numbers that are not separated by addition/subtraction).

In 4x-2y=8, there are no exponents but there are variables, meaning the degree is 1.

Table of degree vs equation types:

Degree       Equation type

1                   Linear

2                  Quadratic

3                  Cubic

Write the equation of the line with x-intercept 3 and passing through the point (5.4)
kykrilka [37]

Answer: y=(1/5)m+3

Step-by-step explanation:

Start with the standard form of an equation of a straight line:  y=mx+b, whre m is the slope and b the y-intercept (the value of y when x=0).

y=mx+b

We know b (3), so:

y=mx + 3

To find the slope, m, we can use the one given point, (5,4):

y=mx + 3 for (5,4) would be:

4 = m*5+3

1 = 5m

m = (1/5)

y=(1/5)m+3

c.

x = 130° (exterior opposite angles)

y + x = 180° (linear pair of angles)

=> y + 130° = 180°

=> y = 180° - 130°

=> y = 50°

d.

z = 100° (corresponding angles)

a = 100° (corresponding angles)

x + 100° = 180° (linear pair of angles)

=> x = 180° - 100°

=> x = 80°

y = x (interior opposite angles)

=> y = 80°

b = y (corresponding angles)

=> b = 80°

g.

a = 112° (vertically opposite angles)

b = a (interior opposite angles)

=> b = 112°

x = 78° (vertically opposite angles)

x + y = 180° (interior angles on the same side of transversal)

=> 78° + y = 180°

=> y = 180° - 78°

=> y = 102°

h.

f = 120° (vertically opposite angles)

e = 105° (vertically opposite angles)

c = 120° (corresponding angles)

d = 105° (corresponding angles)

a + d = 180° (linear pair of angles)

=> a + 105° = 180°

=> a = 180° - 105°

=> a = 75°

b + c = 180° (linear pair of angles)

=> b + 120° = 180°

=> b = 180° - 120°

=> b = 60°

The ratio of mango ice cream to strawberry ice cream is 2 : 5 .Total no. of ice cream is 49.what is the no. of strawberry ice cr
WARRIOR [948]

Answer:

35

Step-by-step explanation:

First, we add the ratio of the mango to strawberry ice cream and we're going to end up with 2+5=7. If we divide 49 by 7, we're going to find out how much we need to multiply to both sides of the ratio to get the specific amounts. So, if we multiply 7 (49/7) to 5, we're going to get 35. Therefore the number of strawberry ice cream is 35.

Also, we can check this by multiplying 7 to 2 as well, where we will end up with 14. 35 + 14 = 49 so we know this is correct!

What is the common ratio of the geometric sequence; *
Tanya [424]

Answer:

C

Step-by-step explanation:

The common ratio r of a geometric sequence is

r = \frac{a_{2} }{a_{1} } = \frac{\frac{10}{3} }{10} = \frac{10}{3} × \frac{1}{10} = \frac{1}{3} → C

If the midpoint between (x, 6) and (-9, 14) is (8, 10), find the value of x
Romashka-Z-Leto [24]
Mid point is found by summation of x
Then divide by 2
And same for y

Since mid point for x is 8
So x+(-9) /2 = 8
X - 9 = 16
X=16+9
X= 25
