Answer:

cubic

Step-by-step explanation:

The degree of a term with one variable is the exponent of that variable. When there is no exponent, the degree is 1. When there is no variable, the degree is 0.

The degrees of the terms in this expression are, left to right, ...

2, 3, 1, 0

The largest of these numbers is the degree of the polynomial: 3.

A polynomial of degree 3 is called a cubic.

A line that passes through (-7, 5) has a slope of 1/2. Which is another point that the line passes through?

d1i1m1o1n [39]

Answer:

(1, 9)

Step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = $\frac{1}{2}$ and (a, b) = (- 7, 5), hence

y - 5 = $\frac{1}{2}$ (x + 7)

y - 5 = $\frac{1}{2}$ x + $\frac{7}{2}$

y = $\frac{1}{2}$ x + $\frac{17}{2}$ ← equation of line

To find another point on the line choose any value of x and substitute into the equation for the corresponding y- coordinate

x = 1 : y = $\frac{1}{2}$ + $\frac{17}{2}$ = 9

Thus (1, 9) is another point that the line passes through

Please i need help whats 1/5x - 2 = 4

Orlov [11]

$\frac{1}{5} x - 2= 4 \\$

Add sides 2

$\frac{1}{5} x - 2 + 2 = 4 + 2 \\$

$\frac{1}{5} x = 6 \\$

Multiply sides by 5

$5 \times \frac{1}{5} x = 5 \times 6 \\$

$x = 30$

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$\frac{1}{5x} - 2 = 4 \\$

Add sides 2

$\frac{1}{5x} - 2 + 2 = 4 + 2 \\$

$\frac{1}{5x} = 6 \\$

Inverse both sides

$5x = \frac{1}{6} \\$

Divide sides by 5

$\frac{5x}{5} = \frac{1}{6} \div 5 \\$

$x = \frac{1}{6} \times \frac{1}{5} \\$

$x = \frac{1}{30} \\$
