Select the description that is true of the equation 3x + y = 7. x-intercept equals -7 x-intercept equals 7 y-intercept equals 7 < is it this? y-intercept equals -7

If x is 6, then 7x= a. 13 b. 42 c. 42x d. 76

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.

The length of an intercepted arc of a central angle of a circle is 4 cm. if the radius of the circle is 5 cm what is the measurement of the central angle to the nearest whole degree
